Cookies are small text files a website stores in your browser. Some are needed for the site to work at all; others protect our forms from bots. This page lists every cookie and similar technology DoRevision uses and explains how you can control them. It should be read alongside our Privacy Policy.
1. Essential cookies
These are set by DoRevision itself and are needed to keep you logged in and to keep forms secure. They do not track you across other websites, and the site cannot work without them, so they are set on every visit.
| Cookie | Purpose | Lifetime |
|---|---|---|
dorevision-session | Identifies your session so the site knows who you are between pages and can save your progress. | 2 hours, refreshed while you are active |
XSRF-TOKEN | Protects forms and actions from cross-site request forgery. | 2 hours |
remember_web_… | Keeps you logged in when you tick "Remember me" so you do not have to sign in on every visit. | Up to 5 years, or until you log out |
invite_ref | Set only when you open a friend's invite link. Remembers who invited you so we can connect you when you sign up. | 30 days |
We also store your light or dark appearance preference in your browser's local storage. It never leaves your device.
2. Bot protection
Sign-up, login and password-reset forms are protected by Cloudflare Turnstile, which checks
that a person rather than an automated script is submitting the form. Turnstile may set a cookie on the
cloudflare.com domain and receives technical information about your browser and connection to
make that decision. See Cloudflare's privacy policy for details.
3. Analytics (no cookies)
We use Cloudflare Web Analytics to count page views. It does not set cookies or store anything else in your browser, and it does not identify individual visitors or follow them across sites. Our own page-view and search records use a one-way hashed session fingerprint rather than anything that identifies you. Because none of this uses cookies or tracks you across sites, no consent is required.
4. No advertising cookies
DoRevision does not show adverts, so it sets no advertising cookies and loads no advertising scripts. No advertising network can set cookies through our pages.
5. How to control cookies
- Browser settings: every modern browser lets you block or delete cookies, and block third-party cookies specifically. Guides: Chrome, Firefox, Safari and Edge.
- Blocking all cookies will stop you logging in, because the essential cookies above are what keep you signed in.
6. Changes
If we add or remove a cookie, we will update this page and the date at the top. Questions about cookies can go to [email protected].
