Cookie Policy
Last updated 3 November 2026
In short
PFA doesn't use advertising or analytics cookies, and it has no third-party trackers. Even its fonts come from PFA's own servers. It uses only the cookies and browser storage it needs to work, or that keep a setting you chose. Those don't need your consent, so PFA doesn't show a cookie banner.
What PFA stores in your browser
- Sign-in session (local storage, a key starting "sb-" and ending "-auth-token"): keeps you signed in. Kept until you sign out.
- pas-shared-computer (local storage): remembers that you ticked "shared or public computer" at sign-in, so PFA signs you out after 15 minutes of inactivity. Removed when you sign out.
- pas_shared_alive (cookie): set on a shared computer so that closing the browser ends your session. Deleted when the browser closes.
- theme (local storage): your choice of light or dark mode. Kept until you clear it.
- sidebar_state (cookie): whether the app's sidebar is open or closed. Kept for 7 days.
- oda:handoff (session storage): carries a lab's starting values into a tool when you open it from the lab. Deleted when you close the tab.
Controlling them
You can block or delete cookies and site data in your browser's settings. If you block them, you won't be able to stay signed in, and some features won't work.
Because PFA doesn't track you, Global Privacy Control and Do Not Track signals don't change anything here.
Changes
If PFA starts using any cookie that isn't needed to run it, we'll update this policy first and ask for your consent where the law requires it.
