1. Scope
This policy applies to the Backranq website, web application and related messages. It does not govern the independent services you connect, such as Lichess, Chess.com, an identity provider or Stripe.
2. Information we handle
- Account information. Your name, email address, profile image and provider account identifier when you sign in.
- Chess information. Public chess usernames, imported games, PGN data, ratings, analysis, training positions and the attempts you make in Practice.
- Preferences and progress. Linked-account settings, sync and analysis choices, notification preferences and learning history.
- Plan and billing information. Your plan, credit balance and subscription status. Payment card details are handled by Stripe and are not stored by Backranq.
- Device and service data. Basic logs, error information, security events and product events needed to operate and improve the service. Offline Coach games and downloaded model assets may remain on your device until you remove them.
The landing-page username search uses public games to prepare a position. The username is not included in onboarding analytics.
3. Why we use information
We use information to:
- provide sign-in, game import, analysis, Practice, Coach and Progress;
- save your settings, training history and subscription entitlements;
- send service, training or product notifications you have enabled;
- protect accounts, prevent abuse and diagnose failures;
- understand aggregated product performance and improve Backranq.
Depending on where you live, these activities rely on performing our agreement with you, legitimate interests in operating a safe and useful service, your consent, or legal obligations.
5. Public chess sources
When you connect or search for a public Lichess or Chess.com username, Backranq requests public profile and game data from that provider. Removing a linked account stops future sync; games already imported remain in your library until you delete them.
6. Retention and deletion
We keep account and training information while your account is active and as reasonably needed to provide the service, meet legal obligations, resolve disputes and protect the service. Retention can vary by record type. You can remove individual games in Backranq and request account-data deletion through Support.
7. Your choices and rights
- Change connected chess accounts and Practice, analysis or notification preferences in Settings.
- Disable browser push notifications through Backranq or your browser.
- Ask to access, correct, export or delete personal information, subject to applicable exceptions.
- Withdraw consent where processing is based on consent.
- Object to or ask us to restrict certain processing where local law provides that right.
Contact us through Support to make a privacy request. We may need to verify your account before completing it.
8. Security and international processing
We use technical and organizational safeguards intended to protect information. No online service can promise absolute security. Providers may process data in countries other than your own; where required, appropriate transfer safeguards apply.
9. Children
Backranq is not directed to children under 13. Do not create an account if you are below the minimum age required in your country without the authorization required by local law.
10. Changes and contact
We may update this policy as Backranq evolves. Material changes will be communicated in the service or by another appropriate channel. Questions can be sent to support@backranq.com.
