This covers both adabreader.com and the Adab Reader browser extension — they share the same backend and the same practices, so one document covers both.
When you generate a reading — by pasting text, uploading a file, or pasting a link on the website, or automatically via the browser extension on a page where it's enabled — the article text is sent to Claude (Anthropic's language model) through our own server-side proxy, solely to generate that one reading. It is not used to train or fine-tune any model, and we do not retain a copy of it on our servers beyond what's needed to serve that single request.
The extension reads the visible text of a page only to detect whether it qualifies as a substantial article and, if so, to extract that text for a reading. It only does this on pages you're browsing while the extension is enabled — you can pause it for a specific site or turn it off globally at any time from the extension popup. It does not read pages while disabled, and it does not track your browsing history.
localStorage on the website, and in chrome.storage.local in the extension — so revisiting the same piece doesn't require regenerating it. This cache never leaves your device.Two services process data as part of how this works: Anthropic (generates the reading from the article text you provide) and Cloudflare (hosts the site and stores shared readings, if you choose to share one). Neither receives anything beyond what's described above.
No accounts, no advertising, no analytics or tracking scripts on the site as of this writing, and we don't sell or share your data with anyone beyond the processing described above.
This is a small, actively-developed project. If anything here is unclear or you have a concern, reach out: contact@adabreader.com.
