Privacy Policy

Effective date: June 15, 2026 — Last updated: June 15, 2026

Madeleine is a French vocabulary learning app published by Aesso ("we", "us", "our"). It is private by design: there is no account, no server, and we collect nothing about you.

The short version

Madeleine has no user accounts and no backend server. Everything you do in the app — your vocabulary progress, review scheduling, profile, and settings — is stored only on your device. We operate no servers that receive your data, and we cannot see it.

What we collect

Nothing. Madeleine has no backend, requires no account or login, and does not transmit your personal information or learning data anywhere.

No analytics or usage telemetry
No crash reporting or diagnostics sent to us
No advertising identifiers or tracking frameworks
No cookies or fingerprinting
No location data
No account, no email, no sign-in
Your data is never sold, shared with third parties, or used for advertising

Where your data lives

Your vocabulary progress, review scheduling, profile name and photo (if you add one), and preferences are stored locally on your device as ordinary files in the app's own on-device storage. There is no account and no server: this data does not leave your device, and we have no access to it.

Vocabulary audio is bundled inside the app for offline use. Madeleine does not send your progress, vocabulary state, or any other data to an AI service, a text-to-speech provider, or any external service.

Subscriptions

Madeleine is a paid app with an auto-renewing subscription processed entirely by Apple through the App Store. We do not receive or store your payment information. Subscription status is verified on your device using Apple's StoreKit framework. Apple's handling of your purchase is governed by Apple's own privacy policy.

Notifications

If you opt in to study reminders, Madeleine schedules local notifications on your device. They are generated and delivered on-device by iOS; no reminder content or schedule is sent to us or to any server. You can turn reminders off at any time in Settings.

Deleting your data

Because everything is stored locally, you are always in control:

Delete My Data in Settings permanently erases your learning progress, profile, and preferences from the device.
Deleting the app removes all of its data from your device.

There is no server-side copy to delete, because there is no server.

Children's privacy

Madeleine is not directed at children under 13. We do not knowingly collect personal information from children — and, in fact, collect no personal information from anyone.

Changes to this policy

We may update this policy from time to time. The "last updated" date above reflects the most recent revision. Continued use of Madeleine after changes constitutes acceptance.
