Privacy Policy

Atelier

Last updated: November 8, 2026

10HALF LLC ("we", "us") respects your privacy and is committed to protecting your personal information. This Privacy Policy explains what information the iOS app Atelier ("the App") handles and how.

1. Information We Collect

We do not collect your name, email address, phone number, location or any other personal information through the App. There is no account and no sign-in.

2. Data Kept on Your Device

The App stores and uses the following data on your device only. None of it is sent to us.

• The progress of the movement's assembly, and the phenomena of the mechanism you have found (the Logbook)
• The modules you have fitted, the dial you have chosen and other settings
• The state of the features you have purchased (the purchase records themselves are handled by RevenueCat, Section 3)

The automatic winding module reads your device's motion sensor (acceleration) to turn the rotor as you move. These values are used for the calculation at that moment only; they are neither stored nor sent.

3. Third-Party Services

• Apple App Store: Apple processes in-app purchase payments. We never receive or store payment information such as card numbers. See the Apple Privacy Policy.
• RevenueCat: We use RevenueCat, Inc. (United States) to manage purchases (confirming and restoring them, and deciding which purchased features are active). The App checks your purchases with RevenueCat when it starts and when you open the module list, so it communicates with RevenueCat even if you have bought nothing. An anonymous user ID issued by RevenueCat, the device identifier for vendors (IDFV, shared by apps from the same developer), your App Store purchase history (product, purchase date, price, currency and so on), the device model, the app and OS versions, your device's language and region settings, your App Store country, and your IP address are sent to RevenueCat and processed in the United States. Your name and email address are never sent. See the RevenueCat Privacy Policy.

The App contains no analytics or advertising services (SDKs), and it does not track you.

4. Retention and Deletion

The data on your device is deleted completely when you delete the App. Purchased features can be recovered with the same Apple ID through "Restore Purchases" in the App.

RevenueCat keeps the purchase history to confirm and restore purchases; deleting the App does not delete it. To request its deletion, contact us at the address in Section 8 with the Order ID from your App Store receipt.

5. Device Permissions

The App does not ask for access to the camera, microphone, photos, location, contacts or notifications.

6. Children's Privacy

The App does not knowingly collect personal information from children under 13.

7. Changes to This Policy

We may update this Privacy Policy as needed. Significant changes will be announced on this page.
