Planned capacity

These are the planned limits for each plan. They are being measured against real storage costs and may change before billing starts. Whichever of the game count or the data allowance you reach first applies, and the import screen shows both before you import.

  • Engine analysis runs in your browser and has no usage meter. Your device and browser still set the limits.
  • No paid cloud analysis is included in any plan.
  • Imports follow each provider’s rate limits and resume if interrupted.

What every plan keeps

  • The same board, the same grading and the same interaction quality. Correctness, privacy and interface do not depend on the plan.
  • You can view, export and delete everything you own, on any plan, at any time.
  • If you move to a lower plan, nothing you made is deleted or hidden. You stop adding past the lower plan’s limits until there is room.
  • No gems, hearts or hints for sale.

How paying will work

A 14-day Pro trial is planned: no card, clear expiry, for an early group of testers. It is not active yet. This page will say when it is.

  • At checkout you will see the tax, the billing currency, the full amount charged and the renewal date before you pay.
  • Prices are in US dollars. An annual plan is charged in full once a year.
  • Cancel from your account settings in one step, with no retention screen. A paid plan keeps working to the end of the period you paid for.
  • Card details go to the payment provider and never reach ChessPillar.

The terms and the privacy notice say the rest. Anything unclear, ask on the contact page.
