Privacy Policy (Piyodoko)
Effective date: October 7, 2026 / Last updated: October 29, 2026
"Piyodoko" (the "App") is a logic puzzle game in which you place chicks on a color-divided board. This policy explains what information the App handles and why.
1. Accounts
The App does not ask for your email address, phone number or real name. To provide online features (rankings, friends, daily puzzle records), a random anonymous user ID is issued automatically on first launch (Supabase anonymous authentication). This ID is not linked to your name, email or other personal details.
If you use “Transfer data”, a random transfer code and a password you choose are attached to this ID (the password is stored encrypted; the developer cannot read it). No email address is registered.
2. Information stored on your device
- Level progress, earned stars, the board of a level in progress
- Hint balance, challenge points and their recovery time
- Daily puzzle results and streaks
- Settings such as sound volume and vibration on/off, and your selected user icon
This data is stored in the App's local storage and is deleted when you uninstall the App.
3. Information sent to and stored on our server (online features)
To provide rankings and friend features, the following is sent to and stored in a Supabase database operated by the developer:
- Anonymous user ID
- Username (2–10 characters, chosen by you), user icon and its background color, friend code
- Cleared level numbers, clear time, mistakes, hints used and clear timestamps
- Daily puzzle start/finish times, time, and the submitted placement (verified to prevent cheating)
- Weekly score
- Friend relationships (requests, acceptances, blocks), challenges and their results, cheers sent and received
- Friend battle records (opponent, the puzzle played, start/finish times, time, mistakes, result, win/loss record)
- Reports (user IDs of the reporter and the reported user, the reported user's username at that time, reason, optional note (up to 200 characters), the screen it was sent from, handling status, date and time)
- Counters used for rate limiting and abuse prevention
- Only if you create a transfer code (“Transfer data”): a copy of the information stored on your device (section 2), used to move your data to another device and updated automatically after that
Information visible to other players
- Rankings: username, avatar, rank and score / clears / time (visible to all players)
- Username search and friend code: username and avatar
- Friends: highest level, today's daily time, weekly score, streak and battle record
- Your opponent in a friend battle: during the battle, in real time, the number of chicks you have found, remaining hearts and connection status; afterwards, the result (time and mistakes)
Please do not use your real name or contact details as your username.
Prohibited conduct and reports
Inappropriate usernames (offensive or obscene words, personal information, etc.), harassing other players and cheating are prohibited. You can report them with "Report" in the App (the reported user is not told who reported them). The developer reviews reports and may rename or hide a username or restrict the use of online features. A username reported by several users may be automatically replaced with another name until it has been reviewed. Report records are used only for handling reports and are deleted within one year after the report has been handled. Deleting your account also deletes reports you made and reports about you.
4. Advertising (Google AdMob)
The App uses Google AdMob, provided by Google LLC, to show optional rewarded video ads that you can choose to watch to receive hints or challenge points. No ads are shown without your choice.
AdMob may collect the advertising ID (Android Advertising ID / iOS IDFA), IP address, device and OS information, and ad view/interaction data to deliver and measure ads and prevent fraud. For users in the EEA, the UK and Switzerland, consent is obtained through Google's consent management tool before ads are served. You can change ad personalization in your device settings or via "広告の設定（プライバシー）" (Ad privacy settings) in the App.
See Google's Privacy Policy (https://policies.google.com/privacy) and How Google uses information from sites or apps that use its services (https://policies.google.com/technologies/partner-sites).
5. Camera
The camera is used only to scan a friend's QR code. Scanning happens on your device; images are neither stored nor sent.
6. Purposes of use
- Saving game progress and providing rankings, friends, challenges and the daily puzzle
- Preventing cheating and handling abuse
- Serving ads
- Investigating bugs and improving the App
7. Sharing with third parties
Except for advertising as described in Section 4 and where required by law, we do not share or sell your information to third parties.
8. Storage location and retention
Our server (Supabase) is hosted in the Tokyo region. Online feature data is kept until you request deletion. Abuse-prevention records are deleted after a limited period.
9. Deleting your information
- Information stored on your device can be deleted by uninstalling the App.
- You can delete your server data (username, records, friends, challenges, cheers, etc.) and the data on your device at any time from My Page → "アカウントとデータを削除" (Delete account and data) in the App.
- If you can no longer use the App (for example, after uninstalling it), contact us at the address below with your friend code or username, and we will delete your data after verification.
10. Children
The App is intended for users aged 13 and over. We do not knowingly collect personally identifiable information from children under 13.
11. Changes to this policy
This policy may be updated due to changes in law or new features. Important changes will be announced in the App or on this page.
