Privacy Policy

The short version

• No account is needed, and we never ask for your name, email or phone number.
• Your learning progress stays on your device and, if you use iCloud, in your own private iCloud storage. We can't see it.
• The App sends anonymous usage data so we can improve it. It isn't linked to you, isn't used for advertising or tracking, and you can switch it off in Settings.

1. Your learning data

Your review progress, starred words, study streak, settings and the optional name you enter for greetings are stored on your device.

If you're signed in to iCloud, your review progress, starred words, streak and study days are also synced between your devices through Apple's iCloud, using your private iCloud database. This data belongs to you. Ambela Labs cannot access, view or sell it. The name you enter is never synced or sent anywhere. Apple's handling of iCloud data is covered by Apple's Privacy Policy.

2. Anonymous usage data

To understand which features are useful, the App sends anonymous usage events to TelemetryDeck, a privacy-focused analytics service. These include:

• When the App is opened, with a snapshot of which levels are active, your streak length, how many words you've studied and mastered, whether reminders are on and whether a widget is installed.
• When a flashcard session or quiz is completed, with the number of cards or the quiz score.
• When levels are changed, reminders are answered, or the Rate or Donate buttons are tapped.
• Standard technical details: app version, iOS version, device model, and language and region settings.

This data does not include your name, email, contacts, location or any of the words you study. TelemetryDeck receives an anonymised identifier (a one-way hash) instead of any identifier that could be traced back to you. The data is not linked to your identity, not combined with data from other companies, and not used for advertising or tracking.

To opt out, go to Settings → Privacy in the App and switch off Share anonymous usage data. The App then stops sending usage data.

3. Notifications

If you allow reminders, they are scheduled on your device. No notification data is sent to us.

4. Links to other services

The App links to its App Store page so you can leave a rating, and to the Ambela Labs page on Ko-fi if you choose to donate. Those services are run by Apple and Ko-fi under their own privacy policies. The App doesn't share any of your data with them.

5. Children's privacy

The App is suitable for all ages. We don't knowingly collect personal information from anyone, including children under 13.

6. Changes to this policy

If this policy changes, the updated version will be posted on this page with a new date.
