AI OBD2 Scanner Overview →

AI OBD2 Scanner Privacy PolicyAI OBD2 Scanner Logo

Effective date: November 3, 2026•Contact: support@kukkabu.com

AI OBD2 Scanner is a smart, read-only vehicle diagnostic application published by Kukkabu Studios. We believe your vehicle telemetry is personal. Our application operates on a local-first architecture where vehicle diagnostic readings remain on your device and are never sold or shared with insurers.

1. Local-First Vehicle Telemetry

AI OBD2 Scanner connects directly to your physical ELM327 OBD-II adapter via Bluetooth or local Wi-Fi. All vehicle telemetry — including Vehicle Identification Numbers (VIN), Diagnostic Trouble Codes (DTCs), sensor parameters (RPM, coolant temperature, speed, fuel trim), Freeze Frame snapshots, and battery voltages — is processed locally in temporary memory on your device. We do not track your GPS location, driving routes, driving behavior, or acceleration profiles. We never sell, rent, or monetize your vehicle data to auto insurers, brokers, advertisers, or third parties.

2. Optional User Accounts & Authentication

You can use all core diagnostic functions of AI OBD2 Scanner (reading and clearing trouble codes, viewing live sensor gauges, checking battery health, and running I/M emissions tests) entirely offline without creating an account or signing in. If you choose to use the AI Diagnostic Assistant or synchronize diagnostic credit balances across devices, you can sign in using Google Sign-In (OAuth). When you sign in, we receive and store: • Your Google User ID • Your email address and display name • Your diagnostic analysis credit balance and transaction timestamps Authentication and cloud balance storage are handled securely through Supabase with Row Level Security (RLS) and encrypted transport (TLS 1.3).

3. AI Diagnostic Assistant Processing

When you explicitly tap "AI Diagnosis" to analyze a vehicle trouble code, the app transmits relevant technical context — the DTC code (e.g. P0420), vehicle make, year, model (if entered), and freeze frame sensor readings — to our secure backend Edge Functions powered by Google Gemini API. This diagnostic context is transmitted securely over HTTPS and is used solely to generate mechanical repair suggestions, severity assessments, and troubleshooting steps. Prompts do not contain personal identifiers, payment details, or location data.

4. In-App Advertising (Google AdMob)

To provide free access to AI diagnostics, AI OBD2 Scanner integrates Google Mobile Ads (AdMob) for optional rewarded video ads. Users only see an ad when they voluntarily choose to watch one to unlock extra AI diagnostic analyses. The Google Mobile Ads SDK may collect and process device identifiers, including the Android Advertising ID (com.google.android.gms.permission.AD_ID), IP address, and interaction data to serve ads, prevent invalid click fraud, and monitor performance. Users can reset their Advertising ID or opt out of personalized ads at any time via Android Settings → Google → Ads.

5. In-App Purchases (Google Play Billing)

Users may purchase optional AI diagnostic credit packages via Google Play In-App Billing. All payment transactions, card processing, and billing operations are handled exclusively by Google Play. Kukkabu Studios never receives, handles, or stores your credit card or financial account numbers.

6. Permissions Used by the App

The app requests only permissions strictly necessary for its functionality: • Bluetooth & Nearby Devices (BLUETOOTH_SCAN, BLUETOOTH_CONNECT): Required to discover, pair, and communicate with wireless ELM327 Bluetooth OBD-II adapters. • Internet (INTERNET, ACCESS_NETWORK_STATE): Required for optional Google Sign-In, AI diagnosis queries, Google Play in-app purchases, and AdMob rewarded ads. • Foreground Service (FOREGROUND_SERVICE): Allows uninterrupted sensor data streaming while the user keeps the diagnostic session active.

7. Data Retention & Account Deletion

Diagnostic sensor data is processed in real time and is not retained on remote servers. If you create an account, your profile and credit balance are retained in Supabase as long as your account is active. You have the right to request the permanent deletion of your account and all associated records at any time. You can submit a deletion request via our web portal at https://kukkabu.com/delete-account?tab=ai-obd2-scanner or by emailing support@kukkabu.com. All account identifiers and stored records will be permanently purged within 30 days.

8. Children's Privacy

AI OBD2 Scanner is a vehicle diagnostic tool and is not directed at children under the age of 13. We do not knowingly collect personal information from children.

9. Contact Us

If you have questions, concerns, or data privacy requests regarding AI OBD2 Scanner, please reach out to our privacy team at support@kukkabu.com.

Looply Overview →

Looply privacy policyLooply Logo

Effective: October 20, 2026•Contact: support@kukkabu.com

What the Android app and these website pages process, why, and how you can request deletion.

1. Operator and contact

Looply is operated under the independent developer name Kukkabu Studios. For service, privacy or account requests, contact support@kukkabu.com.

2. Sign-in and account data

Google is the only sign-in method. Supabase Auth verifies Google identity tokens and manages sessions. Looply stores your Google account identifier, verified email, display name, profile-image URL, user ID and terms acceptance version. We do not receive your Google password. Android session and refresh tokens use secure local storage.

3. Device registration and integrity

Registration sends the app-scoped Android device identifier over HTTPS for server-side keyed hashing. The database stores its hash, device model, Android version and verification time, not the raw identifier. Google Play Integrity processes package, certificate, licensing, device, timestamp and request-binding signals. Tokens are not intentionally logged or retained after verification. Integrity is a risk signal, not an immutable phone identity or guarantee against fraud.

4. Testing and Android Usage Access

Looply stores listings, enrollments, daily check-ins, foreground seconds and credit transactions. Android Usage Access can expose broader usage events on your phone. Looply processes these locally to measure the assigned test package within its testing window, accounting for screen lock/device state. Only the enrollment, device reference, time window and foreground-second total are uploaded, not your complete usage-event stream or full app-use history. Usage Access is requested after an in-app explanation and can be revoked in Android settings. Without it, measured check-ins cannot succeed.

5. Information not requested

The current app does not request contacts, messages, call logs, phone numbers, location, microphone or camera access. It does not record screens, keystrokes or tested-app contents. There are no advertising, analytics or crash-reporting SDKs in the current Android implementation. For troubleshooting, the app writes short diagnostic lines to the phone's own system log: an event name, the error type and a reason code, never message text. Looply does not collect that log. Processing a Google profile-image URL is not access to your photo library.

6. Why we process data

Data supports sign-in, testing coordination, device registration, measured check-ins, internal credits and refunds, security, abuse prevention, support and deletion. We process account and participation data to provide the requested service and security data to protect users and prevent repeated starter grants. Optional Play-account email sharing requires a separate affirmative choice for each listing. Contact support for questions about the legal basis or choices available where you live.

7. Visibility and providers

Listing names, descriptions, package names, Play links and Google Group membership links and addresses are visible to signed-in users who can see the listing. An optional listing logo is stored as a public image that anyone with its link can open. Owners can see participant names, readiness and testing progress. For an email-list test, a reserved tester may enter their Play-account email and explicitly consent to sharing it with that listing owner for test access. It may differ from the Google email used to sign in to Looply. Only that tester and that owner can read it through the participation API; other testers and unrelated owners cannot. Owners must use it only to manage the requested Play test, never for marketing, sale or unrelated contact. Google and developers separately process information when you join their Group or Play test. Supabase processes authentication, database and function data; the current database region is Singapore (ap-southeast-1). Google processes sign-in and Integrity requests. Cloudflare hosts this website, which loads Google Fonts. Zoho Mail handles support correspondence and Zoho Forms handles website contact submissions. Providers may process network/device metadata and information in other countries. We do not sell personal data.

8. Website storage, contact form and external links

The Kukkabu website stores theme, accent, calm-mode and display preferences locally in your browser. Its source does not add advertising trackers. Google Fonts receives font network requests. The homepage contact form sends the name, email, message and referring-page URL you supply to Zoho Forms when submitted so we can handle your inquiry; Zoho may also process network metadata. Zoho support emails and contact submissions stay in our account until we delete them manually; no automatic deletion period is configured. You can request their deletion by emailing support. The deletion page loads Google sign-in only when you choose to verify; Google may use its own cookies or storage. Infrastructure providers can process IP addresses and operational/security logs. Google Play, Groups and independent apps are separate services with their own notices.

9. Active-data retention and deletion

Active account and participation records remain while needed to provide the service, unless removed through supported actions. A submitted Play-account email can be corrected while your place is reserved; correction resets the owner confirmation. To withdraw sharing after readiness, leave the test or contact support. Looply clears the shared email and access confirmation when participation ends, including withdrawal, campaign closure or account deletion. An owner may already have added it to a Google Play list; leaving Looply does not remove that external copy. Owners must remove access-list copies when no longer needed, and you can ask that owner to remove yours. Listing logos are deleted when the owner's account is deleted or moderation removes the listing. Verification challenges expire after five minutes; hourly maintenance removes expired challenges and rate-limit records. Account deletion ends listings and participation, reconciles unused credits and removes the Auth account, profile and linked active device, listing, enrollment, check-in and ledger records. Other participants keep independently earned credits and their own participation history, including a snapshot of a deleted owner's listing. Minimal accounting events containing record IDs, amounts and timestamps survive deletion to reconcile credits and prevent duplicate adjustments; they contain no names, emails, device data or usage proof and have no configured automatic expiry. Uninstalling or removing Google authorization alone does not delete your account.

10. Retained security hashes

The backend retains keyed Google-account and device hashes plus the starter-grant timestamp after deletion solely to prevent repeated starter grants. If an account is suspended when it is deleted, a keyed hash of its Google account identifier is also kept so the suspension continues if that Google account signs in again; deleting an account after a lifted suspension removes it. These hashes can still be personal data; they are not anonymous, not a profile copy, and not used to contact you. There is currently no automatic expiry. Contact support to request review or deletion of retained information; removing a grant record may affect whether a future account can receive starter credits.

11. Support, logs and backups

Zoho support correspondence and contact submissions remain in our account until manually deleted; there is no configured automatic deletion period. You may request deletion from support. Operational logs and backups can remain under Supabase, Cloudflare, Google and Zoho provider settings after active account data is deleted; they are not necessarily erased immediately. We do not promise a fixed backup or log purge period that we cannot verify. Restored data must remain subject to prior deletion requests.

12. Rights, age and changes

Looply is intended for adults aged 18 or older. Contact support if a child supplied account data. Depending on your location, you may have rights to access, correct, export, delete, restrict or object to processing, withdraw consent, or complain to a privacy authority. Requests may require proportionate identity verification, never your Google password. Material changes will be published here and, where needed, explained in the app with renewed acceptance or consent.

13. Safety reports, blocks and moderation

Looply stores abuse reports with the reporter, reported user, related listing, reason, optional details and review decision. Reports are available only to designated moderators, not other testers or the reported user. User-block relationships hide listings and prevent testing between the accounts. Blocking ends active participation between the pair; already-earned credits stay and unused funding is refunded. Unblocking does not restart tests. Moderation can remove a listing or suspend an account, with a recorded decision reason. A moderator cannot decide a report they filed. A removed listing's logo is deleted from public storage. Report records remain until a linked account/listing is deleted; linked blocks and moderator assignments are removed on account deletion. Deleting an independent reviewer account clears that reviewer reference. Do not include passwords, tokens or unrelated personal information in reports. Appeals go to support@kukkabu.com.

14. Activity, issues and notifications

Looply stores service notices, their read status, access problems, outage reports, appeals and moderation decisions. Your notices and issues are private to your account; designated moderators can review submitted issues. Avoid including passwords or unrelated personal information. Account deletion removes your linked notices and issues. Android notifications are optional local reminders controlled by the Profile switch and Android permission settings. The app does not ask for notification permission at sign-in: after your first test or listing it explains reminders and opens Android's permission request only if you agree (Android 13 and later). Refusing notification permission does not prevent participation; you remain responsible for checking your test windows.

Wall Jumper Overview →

Wall Jumper Privacy PolicyWall Jumper Logo

Effective date: July 23, 2026•Contact: support@kukkabu.com

1. Information We Collect Automatically

Wall Jumper is built as a free-to-play, ad-supported game. We do not require users to create accounts, and we do not collect personal information such as names, addresses, or phone numbers directly. However, the Game integrates third-party software development kits (SDKs) that automatically collect certain information from your device. Specifically, we use Google AdMob to serve advertising. The Google AdMob SDK may collect: Device Identifiers (Advertising ID), Device Metadata (model, OS, screen size, IP address, network provider), and Usage Statistics (ad clicks/views and performance logs).

2. Third-Party Service Providers

Third-party service providers collect and process data in accordance with their own privacy policies. You can read the privacy policy of our service provider here: Google Play Services & Google AdMob Privacy Policy (https://policies.google.com/privacy). Google's use of data is further described at https://policies.google.com/technologies/ads.

3. How We Use the Collected Information

  • Ad Delivery: To display ads (personalized or non-personalized based on your consent and device settings).
  • Ad Performance & Bug Fixing: To monitor ad performance, diagnose crashes, and optimize game flow using logs provided by the Google AdMob SDK.
  • Fraud Prevention: To prevent invalid ad impressions and click spam.

4. Consent (EEA, UK, and Switzerland)

If you are located in the European Economic Area, the United Kingdom, or Switzerland, we will show a consent form (via Google's User Messaging Platform) before serving personalized ads. You may choose to receive non-personalized ads instead. You can change your consent choice at any time from within the game under Settings → Ad Consent.

5. Children's Privacy (COPPA & GDPR Compliance)

Wall Jumper is not designed or intended for use by children under the age of 13. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided personal information to third-party services within the game, please contact us at support@kukkabu.com so we can request removal from our partners' servers.

6. Data Retention & Deletion

Because the Game runs locally on your device and does not store user accounts or personal profiles on external servers, the Developer does not hold any user data that can be deleted. Device identifiers collected by Google AdMob are managed directly by Google and can be reset or disabled in your device's operating system settings under "Ads".

7. Your Choices & Control

You can opt out of personalized ads or reset your advertising identifier directly on your device:

  • On Android: Open Settings → Google → Ads → Opt out of Ads Personalization, or Reset advertising ID.
  • On iOS: Open Settings → Privacy & Security → Tracking → turn off "Allow Apps to Request to Track."

EEA/UK/Switzerland users can also reopen the consent form at any time from the game's Settings → Ad Consent screen.

8. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Effective date" above.

9. Contact Us

Numlink Flow Overview →

Numlink Flow Privacy PolicyNumlink Flow Logo

Effective date: October 7, 2026•Contact: support@kukkabu.com

1. Information We Collect Automatically

Numlink Flow is built as a free-to-play, offline-first logic puzzle game. We do not require users to create accounts, and we do not directly collect personal information such as your real name, email address, postal address, or phone number. All puzzle progress, star counts, daily streaks, and game settings are stored locally on your device. However, the game integrates third-party software development kits (SDKs) to serve optional rewarded ads for hints. Specifically, we use Google AdMob, which may automatically collect: Device Identifiers (Advertising ID), Device Metadata (model, OS, screen size, IP address, network carrier), and Usage Statistics (ad clicks, views, and crash performance logs). Google Play Games (optional): if you sign in to Google Play Games Services, Google shares your Play Games profile with the game — your gamer name, avatar, and player ID — and the game sends your leaderboard scores (Daily Flow solve times, Time Blitz scores, and total stars) and unlocked achievements to Google Play Games. Your gamer name and scores may be shown to other players on leaderboards, according to the visibility settings of your Play Games profile. The game is fully playable without signing in. We do not receive your email address, and we do not run our own servers to store this data.

2. Third-Party Service Providers

Third-party service providers collect and process data in accordance with their own privacy policies. We use two services provided by Google: Google AdMob (optional rewarded hint ads) and Google Play Games Services (optional sign-in, leaderboards, and achievements). Both are governed by the Google Privacy Policy (https://policies.google.com/privacy). Google's use of advertising data is further described at https://policies.google.com/technologies/ads, and the data handled by the Play Games SDK is described at https://developer.android.com/games/pgs/data-collection.

3. How We Use the Collected Information

  • Ad Delivery: To display optional rewarded hint ads (personalized or non-personalized based on your consent and device settings).
  • Ad Performance & Diagnostics: To monitor ad delivery, diagnose runtime crashes, and optimize game flow using telemetry provided by the Google AdMob SDK.
  • Fraud Prevention: To prevent invalid ad impressions and automated spam.
  • Leaderboards & Achievements: If you sign in to Google Play Games, to post your scores, show your ranking against other players, record your achievements, and filter out scores that fall outside the leaderboard limits.

4. Consent (EEA, UK, and Switzerland)

If you are located in the European Economic Area, the United Kingdom, or Switzerland, we present a consent form (via Google's User Messaging Platform) before serving personalized ads. You may choose to receive non-personalized ads instead. You can modify your consent choice at any time from within the game under Settings → Ad privacy options.

5. Children's Privacy (COPPA & GDPR Compliance)

Numlink Flow is not designed or intended for use by children under the age of 13. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided personal information to third-party services within the game, please contact us at support@kukkabu.com so we can request removal from our partners' servers.

6. Data Retention & Deletion

Because the game runs locally on your device and does not store user accounts or personal profiles on external servers, the Developer does not hold any user data that can be deleted. Device identifiers collected by Google AdMob are managed directly by Google and can be reset or deleted in your device's operating system settings under 'Ads'. Leaderboard scores, achievements, and your Play Games profile are stored by Google Play Games, not by us; you can delete your Play Games data for this game, or your whole Play Games profile, from the Google Play Games app settings ('Delete Play Games account & data').

7. Your Choices & Control

You can opt out of personalized ads or reset your advertising identifier directly on your device:

  • On Android: Open Settings → Google → Ads → Opt out of Ads Personalization, or Reset advertising ID.
  • On iOS: Open Settings → Privacy & Security → Tracking → turn off 'Allow Apps to Request to Track.'
  • Google Play Games: signing in is optional. You can decline it, and choose who can see your gamer profile and activity in the Google Play Games app.

EEA/UK/Switzerland users can also reopen the consent form at any time from the game's Settings → Ad privacy options screen.

8. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the 'Effective date' above.

Sumo Showdown Overview →

Sumo Showdown Privacy PolicySumo Showdown Logo

Effective date: October 30, 2026•Contact: support@kukkabu.com

1. Summary

Sumo Showdown is a wrestling game for all ages, including children. It has no accounts, no ads, no in-app purchases, no chat, and no third-party advertising or analytics SDKs. We do not collect names, email addresses, phone numbers, photos, contacts, precise location, or advertising IDs. Players aged 13 and over may use Google Play Games for leaderboards and achievements (section 6); younger players never do.

2. Information Stored on Your Device

Your settings, unlocked wrestlers, Tournament stars, trophies, daily missions and win/loss records (including your online record) are saved only on your device. So is whether you answered the first-launch age question as 13 or over; your age itself is not saved anywhere. While an online match is in progress, the game also keeps a short record of it (the room, a random rejoin code and the two wrestlers) so you can reconnect if the game closes; it is deleted when the match ends. We cannot see any of this. You can erase it with Settings → RESET PROGRESS, by clearing the app’s storage, or by uninstalling the game.

3. Online Play

Online play is optional. When you choose ONLINE, the game connects to our online server over an encrypted connection (TLS). The server:

  • Passes your moves (button presses) to the other player in real time. It does not store them.
  • Passes your online name and the face of the wrestler you last played to your opponent. Online names are random, made from a fixed list of friendly words (for example “MIGHTY PANDA 27”), picked again each time you start the game, and sent as word numbers, never typed text.
  • Creates random 6-digit friend codes that stop working when the room closes.
  • For PLAY ANYONE, uses the continent your connection comes from (worked out by our hosting provider from your IP address) to pair nearby players first. The continent is kept only while you wait.
  • For an ONLINE CUP, keeps the players’ online names, wrestler faces, a random rejoin code for each player and the cup’s results while the cup runs, so every player can see their path through the cup. All of it is deleted 10 minutes after the cup ends.
  • Gives your phone a random one-time code so it can rejoin a match within 15 seconds after a dropped connection. It is deleted when the match ends.
  • Receives each phone’s report of who won a match, to count agreed and disputed results (section 4). Results are not linked to players.
  • Uses your IP address to deliver the connection and to limit how many rooms one address can try, which stops people guessing codes. For that limit, the address is turned into a one-way scrambled code and kept in memory for about a minute. We do not log or store IP addresses, and request logging is switched off.

4. Anonymous Online Statistics

To keep online play working well, our server keeps daily totals for each game version: how many online matches were started (with a friend code, with Play anyone or in an Online Cup), how many pairings were on the same or different continents, how many matches finished and how much the game had to correct for lag, how many were stopped because the two phones disagreed, how many results both phones agreed on, forfeits, opponents who never started, reconnects and dropped connections, which input delay was used, and how many Online Cups were started and finished. These totals are counts only. They are not linked to any player, device, IP address, or code, and they are deleted after 90 days.

5. No Chat

There is no chat in Sumo Showdown: no typed text, voice, images, or preset messages. Players only see each other’s random online name and wrestler.

6. Google Play Games (13 and over only)

The first time the game starts, it asks how old you are, in a neutral way that does not hint at any answer. If you are under 13, the game never starts Google Play Games and nothing is sent to it. If you are 13 or over and use Google Play Games on your device, the game signs you in to Google Play Games Services. Google then shares your Play Games profile with the game (your gamer name, avatar and player ID). The game shows your gamer name only to you, in the Online menu; other players in matches see only your random online name. The game sends your trophy total, your number of Online Cups won and the achievements you unlock to Google Play Games. Your gamer name and scores may be shown to other players on Google’s leaderboards, according to the visibility settings of your Play Games profile. We do not receive your email address, and we do not store any of this data on our servers.

7. Service Providers

Our online server runs on Cloudflare, which processes connection data on our behalf to deliver online play: https://www.cloudflare.com/privacypolicy/. The game is distributed through Google Play, which may share aggregated crash and performance reports with us from users who allow it in their Android settings. Leaderboards and achievements for players 13 and over are provided by Google Play Games Services. Google’s services are governed by the Google Privacy Policy (https://policies.google.com/privacy), and the data handled by the Play Games SDK is described at https://developer.android.com/games/pgs/data-collection.

8. Children's Privacy

Sumo Showdown is designed for all ages, including children under 13, and follows the Google Play Families Policy. We do not knowingly collect personal information from anyone, including children: there are no accounts, ads, chat, or tracking, and Google Play Games is only offered, behind a neutral age question, to players who say they are 13 or over. If you are a parent or guardian and have questions, please contact us at support@kukkabu.com.

9. Data Retention & Deletion

Progress on your device stays there until you reset it or uninstall the game. Online Cup data is deleted 10 minutes after each cup ends. The online statistics are anonymous totals that are deleted after 90 days; because they cannot be linked to a person, we cannot find or delete any individual’s share of them. Test versions before 1.5.0 also kept a Weekly League and a Daily Challenge board on our server (a random player ID made by the phone, the generated online name and scores); that data is kept only for a limited time and is deleted entirely when those test versions are retired. Leaderboard scores, achievements and your Play Games profile are stored by Google Play Games, not by us; you can delete your Play Games data for this game, or your whole Play Games profile, in the Google Play Games settings (“Delete Play Games account & data”). We store no other data about you.

10. Changes to This Privacy Policy

If the game changes how it handles data (for example, if ads or purchases are added in the future), we will update this policy before releasing that update and change the 'Effective date' above.
