Privacy Policy — BlackNWhite

1. Who we are

BlackNWhite is developed and published by AIRIZZ (“we”, “us”, “our”). This policy applies to:

the BlackNWhite mobile app for Android (package co.airizz.blacknwhite) and iOS,
the web version of the app at https://game.blacknwhite.io, and
this website, blacknwhite.io,

together, the “Services”. For anything in this policy, contact us at support@airizz.co.

2. Information we process

The app does not ask for, and we do not collect, your name, email address, phone number, contacts, precise or approximate location, advertising ID, or any account credentials. The table below lists everything that leaves your device when you use the app.

What	When	Why	Kept for
Chess position & engine settings — the board as a FEN string, plus difficulty, search depth or think time	Only when you use online engine analysis or play the online AI	To calculate moves and evaluations and send them back to you	Processed in memory and discarded once the response is sent. Not stored or linked to you.
Technical request data — IP address, time of request, user-agent, and request status	With every request to our engine server	To deliver the response, prevent abuse (rate limiting), keep the service secure and fix errors	Rate-limit counters are held in memory for about a minute. Hosting-provider request logs are kept for up to 30 days.

The app works without a connection. If you are offline, or the server can't be reached, the app uses its built-in engine and nothing is sent.

Photos and images

When you choose to scan a board, the photo you take or pick is analyzed by a recognition model that runs entirely on your device. The photo is never uploaded to us or anyone else, and it isn't saved by the app after recognition. Only the resulting position may be sent for analysis, as described above.

Clipboard

The app reads your clipboard only when you tap Paste to import a position or game (FEN/PGN), and writes to it only when you tap Copy. Clipboard contents are not sent to us.

Sharing

If you share a position, game or board image, the app hands it to your device's share sheet. What happens next is controlled by the app you choose to share with and its own privacy policy.

3. Data stored on your device

Your game history, saved positions and app settings (for example board theme, piece set, sound and difficulty) are stored in a local database on your device, or in your browser's storage on the web. This data is not uploaded or backed up to our servers. We cannot see or recover it.

4. Device permissions

Internet: to reach our engine server for online analysis.
Camera and photos: used only when you choose to scan a board. On Android the app uses the system camera and photo picker, so it doesn't ask for broad access to your photo library. On iOS you'll be asked for camera or photo access the first time you scan. You can refuse or withdraw it in your device settings at any time. Every other feature keeps working.

5. This website & beta list

This website uses no cookies, analytics or third-party trackers, and its fonts are served from our own host. Like any website, our hosting provider (Netlify) processes your IP address and browser details to deliver pages and protect against abuse.

If you join the beta list, we collect the email address you enter. We use it only to tell you about the BlackNWhite launch and major beta updates. Submissions are stored with Netlify Forms. You can unsubscribe from any email or ask us to delete your address at any time. We process it because you consented, and you can withdraw that consent whenever you like.

6. How we use information

We use the information described above only to:

provide the Services, including calculating engine moves and analysis;
keep the Services secure and reliable, prevent abuse and diagnose errors;
send launch updates to people who joined the beta list; and
comply with legal obligations.

We don't use your information for advertising, profiling or automated decisions about you, and we don't use it to train machine-learning models.

If you're in the EEA or UK, our legal bases are: performance of a contract (providing the analysis you request), legitimate interests (security, abuse prevention and service reliability), and consent (the beta email list).

8. Data retention

Chess positions sent for analysis: not stored. They're discarded as soon as the response is returned.
Server request logs: deleted automatically within 30 days.
Rate-limit counters: held in memory for about one minute.
Beta-list emails: kept until the app launches and launch updates have been sent, or until you unsubscribe or ask us to delete them, whichever comes first.
On-device data: kept on your device until you delete it (see Deleting your data).

9. Security

All traffic between the app and our servers is encrypted in transit using HTTPS (TLS). Our server accepts only valid chess positions, limits request sizes and rates, and keeps no database of user data. No method of transmission or storage is completely secure, but because we collect so little, there is very little to put at risk.

10. Your rights & choices

Depending on where you live, including the EEA, the UK, California and other US states, India and Brazil, you may have the right to access, correct, delete or get a copy of your personal information, to object to or restrict its processing, and to withdraw consent. We honor these requests wherever you live.

To make a request, email support@airizz.co. We'll respond within 30 days. Because the app has no accounts, we hold almost no information that identifies you. For beta-list requests, please write from the email address you signed up with. You also have the right to complain to your local data protection authority.

We do not sell or “share” personal information as those terms are defined under California law, and we do not process sensitive personal information.

11. Deleting your data

There is no account to delete. To remove everything BlackNWhite stores, delete it from your device:

Android: Settings → Apps → BlackNWhite → Storage → Clear storage, or uninstall the app.
iOS: uninstall the app.
Web: clear site data for game.blacknwhite.io in your browser settings.

To remove your beta-list email, use the unsubscribe link in any email or write tosupport@airizz.co. See also our data deletion page.

12. Children

BlackNWhite is a general-audience chess app and isn't directed at children under 13. We don't knowingly collect personal information from children. The app itself collects no personal information from anyone, and the beta list is meant for adults. If you think a child has given us their email address, contact us and we'll delete it.

13. Purchases

If we offer Premium features in the app, purchases will be processed by Google Play or the Apple App Store. We never receive your card or payment details. We only receive confirmation of what you've bought so we can unlock it. We'll update this policy before any purchase feature launches if it changes how we handle your information.

14. International transfers

Our service providers may process information in countries other than yours, including Japan and the United States. When we transfer personal information out of the EEA or UK, we rely on appropriate safeguards such as the European Commission's Standard Contractual Clauses.

15. Changes to this policy

We may update this policy as BlackNWhite evolves. We'll post the new version on this page and change the effective date at the top. If a change is significant, such as collecting a new type of data, we'll also tell you in the app or on this website before it takes effect.
