Datenschutz

1Who is responsible

UberTuga is the controller under the EU General Data Protection Regulation (GDPR) for the app ÜberDeutsche and the website uberdeutsche.app.

2What stays on your phone

The app keeps the following in its own storage on your device. It is never sent to us or to anyone else, and we cannot see it.

• Your progress: the lessons you have done, your scores, Macht and days in a row, and the cards of the Üben deck.
• Your settings: the look you chose (Hell or Dunkel), the day of your free lesson, and whether your subscription was active at the last check, so the app opens correctly without a connection.
• Your photo, if you choose one: with your permission the app opens your photo library, and you pick a picture. The app keeps a small square copy (256 pixels) to show beside your lines in the talk. You can remove it on the Ich tab at any time.

Deleting the app deletes all of this.

3The subscription: RevenueCat

To sell the subscription and to know whether it is active, the app uses RevenueCat, a service of RevenueCat, Inc., USA. RevenueCat works for us as a processor, under a data processing agreement.

When the app starts, and when you buy or restore a subscription, RevenueCat receives:

• a random ID that the app creates on your phone; it does not contain your name or email address;
• your purchases in this app from Apple or Google: the product, its dates, price and currency, the store country, and whether it is active;
• technical data: the type of device, the version of its operating system and of the app, and your IP address.

We use this only to give you the subscription you bought (Art. 6(1)(b) GDPR). RevenueCat may process the data in the USA; the data processing agreement provides the safeguards the GDPR requires for transfers outside the EU. See RevenueCat's privacy policy.

Payment: Apple (App Store) or Google (Google Play) take the payment, under their own privacy policies. We never see your payment details, your name or your Apple or Google account.

4Corrections over the air: Expo

When it starts, the app asks the update service of Expo (650 Industries, Inc., USA) whether there are corrections to its texts. The request contains the app's project ID, a random installation ID, the version and platform of the app, and, like every request on the internet, your IP address. It contains nothing that names you. We use it to send out corrections quickly (our legitimate interest, Art. 6(1)(f) GDPR). See Expo's privacy policy.

Without a connection, the app works as before and sends nothing.

5This website

uberdeutsche.app is served by Cloudflare (Cloudflare, Inc., USA). When you open a page, Cloudflare processes your IP address and the request (page, time, browser) to deliver the page and to protect it from attacks (Art. 6(1)(f) GDPR). See Cloudflare's privacy policy.

The website sets no cookies, has no analytics and loads nothing from other services: its fonts and pictures come from this site. The look you choose here is kept in your browser's local storage and never leaves it.

6When you write to us

If you write to contact@uberdeutsche.app, we use your address and your message to answer you (Art. 6(1)(b) or (f) GDPR) and delete them once the matter is closed, unless the law requires us to keep them. The mail reaches us through Cloudflare's email routing and is kept in our mailbox at Google (Gmail).

7Your rights

You have the right to access your data, to have it corrected or deleted, to restrict its processing, to receive it in a portable form, and to object to processing based on legitimate interest (Art. 15–21 GDPR). You can also complain to a data protection supervisory authority, in particular in the country where you live.

Most of what the app knows never reaches us. For your purchase data, write to us; your purchase history is also in your Apple or Google account.

8Changes

When the app or the law changes, this page changes with it. The date at the top tells you which version you are reading.
