Písmenka is a free, ad-free early-reading app for children. If something
does not work as expected, send the device model, iOS version, and a short
description of what happened.
✓Gameplay and learning work offline on the device.
✓Each child profile has independent progress and settings.
✓Profiles can practice in Czech or English.

✓The app is free, has no ads, and does not sell data.
Common fixes
•If audio is quiet, check the device mute switch and volume.
•Use the parent settings screen to review audio and backup status.
•If a child is stuck, adaptive practice simplifies and revisits the unit.
•Optional cloud backup requires Google Sign-In from the parent settings area.
Privacy and source code
Písmenka is local-first. Learning progress stays on the device unless a
parent turns on optional backup. The app is intended to be fully open
source, so families can inspect how practice and progress work.
