This policy applies to the Verbindung Android application, published by Pluto Studio.
Verbindung has no accounts, no sign-in and no server of its own. Everything you study stays on your device. The only data that leaves your phone is what the advertising and billing services built into the app send, and both are described below.
Your progress is stored locally on your device in an on-device database. That covers which collocations you have seen, their spaced-repetition stage, review counts, your daily streak, and any entries you add or edit yourself.
None of it is transmitted to us, because there is no server to transmit it to. If you have Android's system backup switched on, Android may include this database in your own Google account backup. That backup is controlled by you and by Google, not by us. Uninstalling the app removes the local data from your device.
The app shows advertising supplied by Google AdMob. To do that, AdMob may access your device's Advertising ID and related device information, and may set identifiers used for advertising and measurement.
Where it is required, for example in the EEA, the UK and Switzerland, the app shows a consent form from Google's User Messaging Platform before requesting any personalised advertising.
Verbindung Plus, the optional one-time purchase, is handled by Google Play Billing, and so is the ad-free subscription that was sold before October 2026. Payment details are handled by Google and never reach us. We receive no card numbers and store no payment information. An exam date you enter for the exam plan stays on the device, like the rest of your learning data.
Example sentences are read aloud using the text-to-speech engine already installed on your device. Which engine that is, and what it does with the text it is given, is a matter between you and that engine's provider. Verbindung sends nothing to a speech service of its own.
The Report button on a card opens your own email app with a prepared message: the German collocation, the meaning shown, the example sentence, the screen and the app version. Nothing is sent unless you send that email yourself. If you do, we receive your email address and what you wrote, use them only to check and fix the card and to reply to you, and do not pass them on.
Verbindung is not directed at children under 13 and we do not knowingly collect personal information from them.
If this policy changes, the updated version appears on this page. Material changes will be noted in the app's release notes rather than only here.
