User Agreement

1. Your account

• Keep sign-in credentials confidential; do not share accounts.
• Do not share, sell, transfer, or pool accounts or paid entitlements once paid plans exist.
• For Lichess/Chess.com imports, use only your own public usernames or PGNs you have the right to upload. Never enter someone else's password anywhere in the Service.

2. Fair use

Free tiers carry reasonable usage limits so the Service stays fast for everyone. You must not:

• Scrape, crawl, or bulk-extract content (including the puzzle library) outside the app's normal features.
• Abuse, automate, or resell API-backed features such as AI explanations, game analysis, or imports, including routing other people's traffic through your account.
• Probe, circumvent, or disable rate limits, access controls, or security features.
• Interfere with other users' use of the Service (spam, flooding, denial-of-service behavior).

3. Content rules

Your uploads (games, PGNs, repertoire names, profile details, and anything posted in community areas) must be lawful and must not:

• Infringe anyone's copyright, trademark, or privacy.
• Contain malware, phishing, or anything designed to harm devices or accounts.
• Harass, threaten, or expose the personal data of others.
• Misrepresent games or results (e.g. uploading engine-played games as your own to manipulate training data).

We may remove content that breaches these rules and will tell you when we do, unless the law or an investigation prevents it.

4. Third-party services

Imports and any future integrations (Lichess, Chess.com, Polar billing) are subject to those providers' own terms. Do not use the Service to violate them, and do not misrepresent your affiliation with any chess platform.

5. Enforcement

Breaches are handled proportionately:

1. Warning: we explain the issue and how to fix it.
2. Restriction: temporary limits on the affected feature (e.g. imports or AI explanations).
3. Suspension or termination: for serious, repeated, or harmful breaches.

Obvious fraud, security attacks, or illegal content may skip straight to suspension. If you believe enforcement was a mistake, appeal within 30 days at support@chessry.com. Appeals are reviewed by a human, not an automated filter. Termination does not extinguish your data rights (see Privacy Policy §8).

6. Reporting abuse

Report violations at support@chessry.com with a description and, where possible, links or screenshots. We act on every report and confirm the outcome to the reporter to the extent privacy law allows.
