Terms of use
Working draft — last updated July 3, 2026.
The deal
FeynmanFSRS is a study tool provided as-is, without warranties. The core is free; Pro is a one-time purchase when payments launch. We'll never sell your data or show ads.
Your content
You own everything you create here. By publishing a deck to the hub you grant other users the right to view and copy that deck within the app; unpublishing stops new copies but doesn't recall ones already made.
Acceptable use
Don't upload content you don't have rights to share, don't harass people in comments, and don't attempt to break or abuse the service (including the AI endpoints). Accounts doing so can be removed.
Honest limits
Scheduling uses FSRS, which is calibrated on recall grades; explanation self-grades are noisier. It works well, but treat intervals as good estimates, not clinical guarantees. The service may change or have downtime; your export always works.
Liability
To the maximum extent permitted by law, FeynmanFSRS is not liable for indirect or consequential damages arising from use of the service.
