Privacy
Plytica is built to need as little of your data as possible. This page says plainly what is stored and why.
What we store
Your email address, display name and preferences; the usernames of the chess platforms you link; the games you import by hand; the analyses, drills and progress you generate. Nothing else.
What we never store
Passwords for Chess.com or Lichess — we never ask for them. Lichess access tokens are used once to read your username and then discarded. Payment details are handled by the payment provider, never by us.
Where analysis happens
Stockfish runs inside your browser. Positions are not sent to a server to be evaluated; only the finished report is saved to your account.
Your control
You can export everything as JSON or delete your account and all attached data from your profile, at any time and without asking us.
