YOUR DATA
Where everything lives
Arty is a desktop app with no backend of mine. This page is the whole story, not a summary of a longer policy.
Stays on your machine
- Your saved words, with the sentences you met them in
- Books, pasted texts, bookmarks and reading position
- Conversation transcripts and written drafts
- Practice time and streaks
Leaves your machine
- The text or audio of the turn you are practising, sent to your model provider
- The word or passage you look up, for the same reason
- YouTube requests, when you search or play a video
That traffic goes from your computer to the service you chose, under their terms. Arty is not in the middle of it and keeps no copy. If you run a local model instead, none of it leaves at all.
Things Arty does not do
- No accounts, so there is nothing to log in to and nothing to leak.
- No analytics, no crash reporting, no phone-home version check.
- No ads and no data sold, now or under any future funding model.
- No data collected from children, or from anyone else — there is nothing to collect.
If you want to verify any of this rather than take my word for it, the source is public and the network calls are easy to find.
This website
arty.caraus.eu is a static site with no analytics, no tracking pixels and no advertising. It sets no cookies. Your light or dark theme choice is remembered in your browser's own local storage and is never sent anywhere. Fonts come from Google Fonts and the download page embeds a Ko-fi button; both are third parties that see your IP address as part of serving those files, as any web request does.
Changes and contact
If this policy changes, the new version is published on this page and the date below changes with it. For any question about it — including a request to delete data, though there is none of yours to delete — you can reach me through about.caraus.eu ↗.
