Gloss is a minimalist reader for the things you already read — DRM-free EPUBs, PDFs, text and Markdown notes, and web articles — that adds AI "margin notes" in the voice of an author or an expert guide. This policy explains exactly what leaves your device.
Files and articles you import — EPUBs, PDFs, text/Markdown, and saved web pages — are stored only on your device. The full document is never uploaded to our servers or anyone else's.
When you highlight a passage and ask for a margin note, we send only:
This is sent over an encrypted connection to our backend (Supabase), which calls Anthropic's Claude API to generate the note. We never send the whole document — only the highlighted passage and its bounded context, regardless of whether the source is a book, a PDF, a personal note, or a web article.
To sign in and meter usage we store your email address and a user ID. We keep a usage log (timestamp, model, token counts) to enforce limits and understand cost. We do not sell data, run ads, or use third-party trackers.
Author "voices" in Gloss are an AI interpretation, not the real author, and may be inaccurate. Notes are generated by Anthropic's Claude; see Anthropic's policies for how they handle API data.
You can delete your highlights and notes in-app, and request account deletion and a data export from Settings. Subscriptions are managed in your Apple Account.
