Cookies Policy
Last updated: 8 October 2026
This page explains the cookies and browser storage that Medical Study Atlas uses, and why. In short: we use only what the site needs to work and to remember your choices. There are no advertising cookies, no tracking cookies and no third-party cookies.
1. Cookies
A cookie is a small text file a website saves in your browser. We use one cookie:
| Cookie | What it does | How long it lasts |
|---|---|---|
sb-access-token |
Keeps you signed in, so protected pages and lecture files open for your account. Set by this site only (first-party), sent only over HTTPS. | About 1 hour, renewed automatically while you use the site; removed when you sign out |
This cookie is strictly necessary: without it you cannot stay signed in.
2. Browser storage
Like cookies, the site also saves a few small values in your browser's local storage (and one in session storage). They never leave your device except where noted.
| Name | What it does | How long it lasts |
|---|---|---|
sb-…-auth-token |
Your sign-in session (including the automatic guest account during free-access periods). Used to talk to our sign-in provider, Supabase. | Until you sign out or clear site data |
atlas-university, atlas-stage |
Remembers which university and stage you chose, so you don't have to pick again | Until you change it or clear site data |
atlas-theme |
Remembers light or dark mode | Until you change it or clear site data |
atlas-visits |
Counts your visits so the "install the app" suggestion is only shown to returning visitors | Until you clear site data |
atlas-install-dismissed |
Remembers that you closed the install suggestion, so it stays hidden for 14 days | Until you clear site data |
atlas-streak |
Old copy of your daily streak from before streaks were saved on your account; deleted automatically | Removed on your next visit |
atlas-reloaded-for (session storage) |
Lets the installed app update itself once when a new version of the site is published, without reloading in a loop | Until you close the tab or app |
3. Visitor statistics
We use Vercel Web Analytics and Vercel Speed Insights to count page views and measure how fast pages load. They do not use cookies and do not store anything in your browser. Visitors are counted in an anonymous way that is reset every day, and we only see totals (for example, how many people visited a page), never who you are.
4. Things we do not use
- No advertising or marketing cookies.
- No social-media buttons or trackers.
- No third-party cookies. Our fonts are served from our own site, not from Google.
5. Your choices
- Because we only use cookies and storage that the site needs, we do not show a cookie banner.
- You can delete or block cookies and site data at any time in your browser settings. If you do, you will be signed out, and your choices (university, stage, theme) will be reset. Your study streak is saved on your account, so it comes back when you sign in again.
6. Contact and changes
