Privacy Policy
Lingon
Last updated: March 23, 2026
Lingon respects your privacy. This policy explains what data the app accesses and how it is handled.
Data Stored on Your Device
Your saved articles, reading preferences, and settings are stored locally on your device. No account or sign-in is required.
On-Device Translation
Translations are processed on-device using Apple Foundation Models whenever possible. No text is sent to external servers for standard translations.
News Content
The app fetches news articles from public RSS feeds (SVT, TV4, Expressen, 8 Sidor). Firebase is used to deliver pre-translated article data.
Pro Features & Third-Party Services
Pro subscribers may have article text sent to Google's Gemini API for cloud translation, AI simplification, and AI chat. Only the article text and your chat messages are sent — no personal information is included.
Subscriptions
Subscription purchases are handled entirely by Apple through StoreKit. Lingon does not process or store any payment information.
No Tracking or Advertising
Lingon does not include advertising, does not use tracking frameworks, and does not collect personal data.
Data Deletion
Deleting the app removes all locally stored data.
