What Etyr collects
Etyr is built to be local-first. It has no accounts, no sign-in, and no profile. It does not collect browsing history, page content, bookmarks, or any personal information.

Network requests
Etyr makes network requests to public dictionary APIs (such as the Free Dictionary API) and optionally AI fallback services (Google Gemini, Hugging Face) to fetch definitions when you look up a word. No other data is transmitted. Definitions are cached locally so repeat lookups happen offline.

Local storage
Everything else lives in your browser’s local storage on your device:

Words you save to your vocabulary
Your lookup history
Your settings (theme, pronunciation, site exclusions)
The dictionary cache described above
What is intentionally not collected
No analytics, trackers, or cookies
No advertising identifiers
No reading history or page content
No keyboard or form input beyond the words you explicitly look up
Changes
If this policy changes, the version on this page will be updated with a new “last updated” date.
