Privacy Policy
Effective date: March 22, 2026 · App: jAMSKOOL Ear Trainer (iOS)
jAMSKOOL Ear Trainer does not collect, store, transmit, or share any personal information. Your data stays on your device. Always.
Who we are
jAMSKOOL Ear Trainer is an iOS application developed and published by jAMSKOOL. If you have any questions about this privacy policy, you can contact us at [email protected].
What information we collect
We collect no personal information whatsoever. The app does not require you to create an account, provide your name, email address, or any other identifying information.
The only data the app stores is your training progress — quiz scores, streaks, and session history. This data is:
- Stored locally on your device only
- Never transmitted to any server
- Never accessible to us or any third party
- Deleted permanently when you delete the app
Microphone access
The app requests access to your device's microphone solely to enable the singing quizzes and tuner — features that detect the pitch of your voice in real time.
Your microphone audio is processed entirely on your device. It is never recorded, never stored, and never transmitted anywhere. We have no access to it. No audio data leaves your device under any circumstances.
You can revoke microphone permission at any time in your iPhone's Settings. Revoking access disables the singing quiz features but does not affect the rest of the app.
Purchases
jAMSKOOL Ear Trainer is a one-time purchase made through Apple's App Store. All payment processing is handled entirely by Apple. We do not receive, store, or process any payment card or financial information. Apple's privacy policy governs how your purchase data is handled: apple.com/legal/privacy.
Third-party services
The app does not integrate any third-party analytics, advertising networks, social media SDKs, or tracking tools. There are no third parties with access to any data generated by your use of the app.
Children's privacy
jAMSKOOL Ear Trainer is suitable for users of all ages. Because we collect no personal information from anyone, there are no special considerations for users under the age of 13. We do not knowingly collect any data from children or adults.
Changes to this policy
If we ever make material changes to this privacy policy — for example, if a future version of the app adds any data collection — we will update this page and revise the effective date at the top. We encourage you to review this page periodically.
