Privacy Policy for Ionika
Last updated: November 11, 2026
Ionika keeps your learning progress, watchlists, and settings on your device only. There is no account and no server of ours, so nothing about your learning leaves your device through the app.
The app does not need an account, and we do not run any servers where your data could end up.
Everything you create (learning progress, watchlists, and settings) stays on your device.
You get the app through the Apple App Store. Apple is responsible for download, payment, and updates; we have no access to that data. Apple's privacy policy applies: https://www.apple.com/legal/privacy/
If you have turned on "Share with App Developers" in the iOS settings, Apple provides us with anonymous crash reports and usage statistics. They do not identify you.
The app is also available on Google Play. Google is responsible for download, payment, and updates there; we have no access to that data. Google's privacy policy applies: https://policies.google.com/privacy
Whatever happens only on your device or in your private iCloud does not reach us; we do not process that data.
If you e-mail us, we process your address and message to answer you (Art. 6(1)(b) GDPR for questions about a purchase, otherwise Art. 6(1)(f) GDPR).
What the app stores on your device stays there until you delete it in the app or remove the app. Data in your iCloud can be deleted in your device's iCloud settings.
We delete e-mails to us once your request has been resolved, unless statutory retention obligations apply.
You have the right to access (Art. 15 GDPR), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20), and to object to processing based on legitimate interests (Art. 21). You can withdraw consent at any time with effect for the future (Art. 7(3)).
Since we do not keep accounts and the app does not identify you, we often cannot attribute data to a person (Art. 11 GDPR). Write to us anyway; we are happy to help.
You can lodge a complaint with a data protection supervisory authority (Art. 77 GDPR), for example the one responsible for us: the data protection authority of Lower Saxony (LfD Niedersachsen), Prinzenstraße 5, 30159 Hannover, Germany, https://www.lfd.niedersachsen.de
