Chord Trainer (“the App”) is a music education application. We respect your privacy.
We do not collect, transmit, or sell personal data. The App does not require an account and does not use analytics, advertising, or tracking.
Practice statistics (scores, streaks, achievements, chord history, difficulty, key, and language) are stored locally on your device. This data never leaves your device unless you back up the device through Apple’s standard backup services.
The App may offer optional Support tips through Apple In-App Purchase. Payment is processed by Apple. We do not receive your card number, Apple ID password, or billing address. Tips do not unlock extra features; the App works fully without them.
Practice works fully offline. Optional In-App Purchases contact Apple’s servers. The App does not load third-party analytics, advertising, or remote fonts.
The App synthesizes piano sounds locally with Web Audio. It does not access your microphone, camera, or location.
The App is suitable for all ages and does not knowingly collect information from anyone.
We may update this policy. The updated date above will change when we do.
