Games and analysis
Why are my newest games missing?
Confirm the correct public username under Settings, then open Games and use Sync. Provider delays and rate limits can postpone a sync without removing games already in your library.
Why is a game not producing Practice positions?
The game needs current analysis and a stable, meaningful decision that passes Backranq's verification. A completed analysis can legitimately produce no saved position.
Can I analyze without server credits?
Yes. Browser analysis runs locally while the tab stays open. Server analysis can continue after you leave and may use plan credits or limits.
Practice and Coach
How is my Practice move graded?
Backranq compares the move with verified engine evidence for that exact position. Good alternatives can be accepted even when they differ from the move played in the source game.
What happens when grading cannot finish?
Your legal move is not silently marked wrong. Backranq shows an unresolved state and lets you retry local analysis or reveal the verified line where available.
How does offline Coach work?
Open Play online once to prepare the engine and device access. The active game is saved locally. When you reconnect, completed games can be saved and analyzed in your library.
Plans and billing
Where can I manage my subscription?
Open Settings and go to Plan & billing. If your plan is managed by Stripe, the billing portal lets you update payment details or cancel future renewal.
My Pro invitation does not work. What should I check?
Sign in with the exact invited email address. Invitation links can expire or be replaced when resent; ask the sender for the newest link.
Still stuck?
Email support@backranq.com. Include the affected page, your chess provider, approximate time and a screenshot if possible. Never send a password or payment-card number.
