Latest updates
3.3.3
New:
- Resetting your learning stats now syncs safely across devices: your other devices notice the reset and ask whether to reset too, keep their data and restore your account, or decide later.
Improved:
- While that choice is pending, syncing pauses and a clear indicator shows why - no more silent merging of old progress back into a freshly reset account.
