Privacy & Data

Quick Answer

The atlas is a single self-contained page with no accounts and no server-side profile of you. The only data it keeps is your own study progress — spaced-repetition state and bookmarks — and that is stored locally in your browser, on your device, never transmitted to us. There is nothing to log in to, and nothing about your reading is sent anywhere.

What is stored, and where

A few features remember your activity so they can be useful across visits: the spaced-repetition scheduler, any bookmarks or "My Atlas" selections, and your light/dark theme preference. These are written to your browser's local storage on your own device. They are not uploaded, not shared, and not visible to anyone but you. Clearing your browser's site data — or using the reset control inside a feature — erases them completely.

No accounts, no tracking cookies, no ads

The atlas has no login system, so it never collects a name, email, or password to use the reference. It sets no advertising or cross-site tracking cookies, shows no advertising, and does not sell or share data — there is no data to sell. The browser storage described above is functional, not tracking: it exists only to make your own tools work.

Analytics, if any

If the hosted atlas ever uses analytics, the intent is privacy-preserving, aggregate usage counts only — the kind that record that a page was viewed without cookies and without identifying the reader. Any such measurement, and its provider, would be named here before it is used. As shipped, the file performs no analytics of its own.

External links

The atlas links out to primary sources — journal DOIs, guideline pages, trial registries. Once you follow a link you are on that third party's site, under their privacy practices, which we do not control. Verifying a claim against its primary source is encouraged; just be aware the destination sets its own terms.
