Help & feedback
Questions, bugs, and ideas — we read everything at support@flexichess.com. We aim to reply within a business day.
Common questions
- Do I need an account?
- Not to explore — the board, engine analysis, and Game Search on the game database all work without signing in. You do need a free account to import your own games and build a library (which then backs up and syncs across devices), and for Pro features.
- Where is my data stored?
- Your library is held in your browser, which is what makes opening a game instant — analysis runs on your machine rather than on ours. Once you're signed in with a verified email address, it also backs up to your account automatically, so your games are on every device you use and survive clearing your browser. That backup is automatic and can't be switched off — your library lives in your account, and the copy in your browser is a working cache of it. Nothing is uploaded while you're signed out, before your email is verified, or for a collection larger than your plan's cloud limit; the Library marks those as "This device only". Accounts are secured by Clerk. (Building a library requires a free account.)
- How do I share a position?
- Use Board → Copy position link in the workbench. Anyone opening that URL loads the same FEN in FlexiChess.
- What is Pro?
- Pro is the edge: a coach sized for daily prep (up to 35 questions a week), and a cloud library across all your devices (the exact numbers are in the Plan limits table below). If you do reach the coach ceiling, you can buy a top-up rather than wait for the reset. The full workstation — database search, FSRS training, game review — is free, with sync via a free account. See /pricing.
- How does Pro billing work?
- Pro is a monthly or annual subscription processed by Polar, our Merchant of Record. You can cancel anytime from your account or Polar's customer portal — or just email support@flexichess.com and we'll cancel it for you; your plan stays active until the end of the paid period. If Pro isn't right for you, email support@flexichess.com within 14 days of your first payment — monthly or annual — and we'll refund it in full, no reason needed. Later renewals aren't covered by that guarantee, so cancel before a renewal date if you don't want to be charged. Your rights under consumer law apply on top of this either way.
Plan limits
Coach quotas reset weekly (Monday UTC). Pro limits are fair-use ceilings sized for daily prep; run past the coach ceiling and you can buy a top-up instead of waiting for Monday. Cloud caps are total storage, not monthly. See pricing.
