Privacy

up103 is run by one person, and this page says plainly what happens with your data — on this website and in the app.

This website (up103.com)

This site uses Google Analytics to count visits and see which pages get read. Google sets cookies for that. Nothing else is tracked here: no mailing list, no ads, no other third-party scripts.

The app (app.up103.com)

You sign in with your email address — it's used for the magic-link sign-in and for nothing else. When you log a study session, your note photos or typed notes are processed with AI services (Anthropic Claude for text, ElevenLabs for audio) to build your grammar profile and generate your listening decks. Your entries and profile are stored in your private account on EU servers.

Your notes stay yours. They aren't shared, sold, or used for anything beyond making your own decks.

Removing your data

If you want your account and data deleted, say so via the feedback option in the app and it will be removed.
