PitchGarden Privacy Policy

Last updated: 23 September 2026

The short version PitchGarden collects nothing about you. Audio is analysed on-device and immediately discarded. No account, no cloud, no ads, no tracking.

What this policy covers

This policy describes how the PitchGarden iOS app (the "App"), published by Ilia Filiaev (the "Developer"), handles your information.

Data we collect

None. The App does not have user accounts, does not require sign-in, and sends nothing to the Developer. Its only network connection is to validate in-app purchases through RevenueCat, described under Third parties.

Data the App reads on your device

Microphone audio. While the tuner screen is open and the App is in the foreground, the App reads short audio buffers from the microphone via Apple's AVAudioEngine. Each buffer is fed through an on-device pitch detector and immediately discarded — no audio is recorded, saved, transcribed, or transmitted.
Session history. Summary outcomes (interval correct/incorrect, tuner minutes, dominant note) are stored on your device using SwiftData. Raw audio is never persisted. This data never leaves your device.

Permissions the App may request

Microphone — required only to use the tuner screen. The ear-training game does not need it.

Third parties

The App uses RevenueCat (revenuecat.com) to validate in-app purchases. RevenueCat receives the App Store purchase receipt, an anonymous app user ID created on your device, and the basic technical details any network request carries, such as IP address, app version and device model — never your name, email address or payment details. It processes them under its own privacy policy: revenuecat.com/privacy. The App contains no advertising, attribution or tracking SDKs. Nothing else is shared with or sold to anyone.

Children's privacy

The App is suitable for all ages and does not knowingly collect any information from children or any other users.

Your rights

Because we do not collect or store your data on our servers, there is nothing to access, export, or delete. You can remove all on-device data by deleting the App from your iPhone.

Changes to this policy

If we change this policy, we will update the "Last updated" date above. Material changes will be announced in the App release notes.
