Privacy Policy

Last updated: March 2026

Lexiklar is a fully offline German dictionary app. This policy describes what data the app handles and how.

Data stored on your device

Lexiklar stores the following data locally on your device only:

• Search history — recently visited and frequently viewed words
• Favorites — words you have saved
• Preferences — theme, language, and display settings

This data never leaves your device and is never transmitted to any server. You can clear it at any time in Settings.

No account required

Lexiklar does not require an account, login, or any personal information to use.

No analytics or advertising

The app contains no analytics, crash reporting, advertising SDKs, or third-party tracking of any kind.

Data reports

The app includes optional "Report missing word" and "Report incorrect data" features. When you submit a report:

• The word name, any details you type, and the app/database version are sent to a server operated by us (Cloudflare Workers).
• Reports are stored privately and are only visible to the app developers.
• No personal information (name, email, IP address) is stored with your report.
• Your IP address is temporarily processed for rate limiting and is not stored permanently.

Reports are voluntary and the app functions fully without them.

Dictionary updates

The app periodically checks for dictionary updates by making a network request to our CDN (Cloudflare R2). On the web version, the dictionary database (~50 MB) is downloaded on first use after your confirmation. These requests may cause your IP address to be logged by Cloudflare as part of their standard server logging. No personal data is sent by Lexiklar in these requests.

Dictionary data

The dictionary content is stored entirely on your device after the initial download. It is derived from German Wiktionary (CC BY-SA 4.0) and frequency corpora. No user data is associated with or transmitted alongside this data.
