Privacy policy

1. Data controller

Cedrik Razafimanantsoa, sole trader (entrepreneur individuel) trading as NotePrecision, 54 rue de la Bonne Aventure, 78000 Versailles, France. Business registration number (SIRET) 951 096 072 00016.

2. Data collected by the website

This website sets no cookies, uses no trackers and collects no browsing data.

If you write to us, your email address and the content of your message are kept for as long as it takes to handle your request, and for no more than three years.

3. Data processed by the app

The app works without an account and without registration, and training works without an internet connection. Only the in-app purchase goes through the store, which needs the network to process it. You can use all of the app without giving us any information whatsoever.

The following is stored on your device only:

• the profiles you create: the first name or nickname you choose, and an avatar picked from the catalogue the app offers;
• your settings: enabled intervals, playback mode, practice goals, instrument;
• your training history: sessions, answers given, accuracy, response times, playback mode heard;
• your progress: streaks, unlocked achievements, journey advancement;
• the sessions you schedule in the app’s built-in planner;
• the recommendations computed by the ZDP engine from that history.

This data exists solely to run your training and compute your statistics. NotePrecision has no access to it. It is passed to no one, is neither sold nor rented, and serves no advertising purpose.

The app contains no audience measurement tool, no tracker, no advertising kit and no third-party analytics or crash-reporting service.

iOS and macOS

Storage is local (SwiftData), with no iCloud synchronisation: your data is not replicated across your devices.

Any analysis offered by Apple Intelligence, where your device supports it, runs on the device itself. Nothing is sent to a server.

If you choose to add a session to your calendar, the resulting event then follows your calendar account’s own synchronisation, like any other event in your calendar.

Android

The app declares five permissions. Three are tied to the in-app purchase and added by Google’s payment library: internet access, network state and Google Play billing. They are used only to process the purchase. The other two serve session reminders, if you turn them on: showing notifications, requested only when you schedule a session with a reminder, and device startup, to reschedule your reminders after a restart. None of the app’s own code uses the network: your training data never leaves your device. It is written to the app’s private storage area, which other apps cannot read.

The app is also excluded from Android’s automatic backup: its data is copied nowhere, neither to your Google Drive storage nor during a device-to-device transfer. The trade-off is that moving to a new phone means starting over, as on iOS.

4. Purchases

The app offers a single purchase that unlocks every feature. There is no subscription.

Payment is handled entirely by the store, Apple’s App Store or Google Play depending on your device. We receive no payment data: no card number, no purchaser identity. The app only records, on your device, the fact that the purchase was made.

How those stores process your data is governed by their own privacy policies (Apple, Google).

5. Children

The app is aimed in part at music students, including minors. Since no data is collected or transmitted, no personal information about a child ever reaches us. The app requires no account and displays no advertising.

6. Your rights

The General Data Protection Regulation (GDPR) grants you rights of access, rectification, erasure, objection, restriction and portability.

Because the app’s data is stored on your device and is inaccessible to us, you control it directly: deleting a profile in the app erases the data attached to it, and uninstalling the app erases everything.

For the data we do hold, namely the messages you send us, write to contact@noteprecision.com.

You may also lodge a complaint with the French data protection authority, the Commission nationale de l’informatique et des libertés (CNIL), www.cnil.fr.

7. Changes

This policy may change, in particular when new versions of the apps are released. The date of the latest update appears at the top of this page.
