Privacy & trust
Your board, your data.
Chaturanga is built so the things you'd expect to stay private, stay private — in plain language, not fine print.

Full game records, PGNs, and move history stay on your device.
Only what needs to sync
Aggregate stats — XP, level, ELO, wins, losses, draws — and progress can sync when you're signed in.
Your API key stays yours
AI keys are stored securely on device and are never synced by Chaturanga.
