Privacy Policy

Effective date: June 15, 2026 — Last updated: October 14, 2026

Madeleine is a French vocabulary learning app published by Aesso ("we", "us", "our"). The app is private by design: there is no account, and we collect no learning data.

The short version

Madeleine has no user accounts. Everything you do in the app — your vocabulary progress, review scheduling, and settings — is stored only on your device, and we cannot see it. The only records we keep are Apple's subscription records and, for installs that came from one of our App Store ads, which ad it was. Neither includes your name, email address or Apple Account.

What the app collects

No personal information and no learning data. Madeleine requires no account or login, and your learning data never leaves your device.

  • No usage analytics: we never see what you study or how you use the app
  • No crash reporting or diagnostics sent to us
  • No advertising identifier (IDFA), no tracking frameworks, and no tracking across other companies' apps or websites
  • 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

Subscription and ad records

When a subscription starts, renews, is canceled, fails to renew or is refunded, Apple sends us a record of it: the plan, price, currency, App Store country, dates and Apple's transaction number. The record does not include your name, email address, Apple Account or payment details.

From version 1.7, if you install Madeleine after tapping one of our ads on the App Store, the app sends us Apple's ad attribution token and a random install ID that the app makes, one time. We ask Apple which ad campaign and search keyword led to the install, and keep that with the install ID. When you subscribe, the same install ID is attached to the purchase, so we can see which ads lead to subscriptions. Apple provides this without the tracking prompt, and it is not tracking across other companies' apps or websites.

We use these records only to learn which marketing works. They are stored with Cloudflare, kept for at most 400 days, and never sold or shared.

Website analytics

This policy page and madeleineapp.com use Visitors.now to measure page views, repeat visits, performance, referral sources, App Store clicks, and audio-sample plays. Visitors stores a first-party visitor identifier in your browser. The website has no account, so it does not send a name, email, or Madeleine learning data to Visitors. Visitors does not send analytics when Global Privacy Control or Do Not Track is enabled in your browser.

Where your data lives

Your vocabulary progress, review scheduling, and preferences are stored locally on your device as ordinary files in the app's own on-device storage. There is no account: 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.

The widget and Spotlight

Madeleine and its Word of the Day widget share a private container on your device. The widget shows one French word a day from the curriculum bundled in the app, in the masculine or feminine form you chose, on the Home Screen or the Lock Screen. Madeleine also adds the words you have mastered to Spotlight, so iPhone search can find them. Both stay on your device and send nothing anywhere. Delete My Dataremoves the Spotlight entries and resets the form preference the widget reads.

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 also sends us the subscription records described above. 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 and preferences from the device.
  • Deleting the app removes all of its data from your device.

There is no server-side copy of your learning data. The subscription and ad records hold no name or contact details, so we cannot match them to you, and they are deleted after 400 days.

Children's privacy

Madeleine is not directed at children under 13. We do not knowingly collect personal information from children.

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.
