Privacy Policy
Effective 30 September 2026
The short version
- No account, no sign-up: we don’t know who you are.
- Microphone audio is analysed on your device, in real time. It is never recorded, stored, or sent anywhere.
- Your settings, streaks, and practice stats live only on your device.
- No ads inside the app. We use anonymous usage statistics, and share limited install and subscription events with Meta to measure our own ads. We never sell your data.
1. No accounts, no personal data
RootNote has no sign-up. We don’t collect your name, email address, contacts, or location, and we run no servers of our own that receive data from the app. The limited technical data described in section 5 goes to two service providers.
2. The microphone
The app asks for microphone access for exactly one reason: to hear the notes you play and check them against the scale or chord on screen. The audio is converted to pitch information on your device the instant it is heard, then discarded. No audio is recorded, saved, or transmitted, and the microphone is only active during a practice session.
You can withdraw microphone access at any time in iOS Settings → Privacy & Security → Microphone. The app will keep working, but it won’t be able to hear your playing.
3. Data stored on your device
Your preferences (like mic sensitivity and fingering hints), your onboarding answers, and your practice history (streaks, stats, records) are stored locally on your device only. They are included in your normal device backups, and deleting the app deletes them.
4. Purchases
Subscriptions are processed entirely by Apple. We never see your payment details. The app checks your subscription status on-device through Apple’s StoreKit framework; that check doesn’t send us any information about you.
5. Analytics and third parties
The app shows no advertising. It uses two third-party services:
- TelemetryDeck (anonymous usage statistics). The app sends events such as which onboarding steps you reach, your onboarding answers (goal and skill level), and whether the paywall was shown or a purchase attempted, tagged with an identifier that is hashed on your device, so neither we nor TelemetryDeck can tell who you are. See TelemetryDeck’s privacy policy.
- Meta (Facebook) SDK (ad measurement). We advertise RootNote on Facebook and Instagram. To learn which ads work, the app tells Meta when it is installed and opened, and when a free trial or subscription starts (with its price and currency). With these events Meta receives technical data: device model, OS version, app version, IP address, and an app-specific device identifier. The app does not ask to track you across other companies’ apps and websites, and does not access your device’s advertising identifier. Meta processes this data under its own privacy policy.
We do not sell your data, and we share it only as described above.
6. Children
RootNote is not directed at children under 13, and we do not knowingly collect personal data from them.
7. Your rights
Privacy laws such as the GDPR give you rights over personal data a company holds about you. We hold nothing that identifies you, so there is nothing for us to access, correct, export, or erase. For data Meta holds, use Meta’s data request form. To remove everything the app stores locally, delete the app from your device.
8. Changes to this policy
If the app’s data practices ever change, we’ll update this page and its effective date before the change takes effect.
