1. What cookies are
Cookies are small text files a website stores in your browser. They let a site remember things between requests — for example, that you are logged in.
2. The cookies we use
1 Sign uses only strictly-necessary cookies needed to run the service securely. We do not use advertising or third-party tracking cookies.
| Cookie | Purpose | Expiry |
|---|---|---|
SIGNOFFSESS | Keeps you signed in to your account during a session (authentication). | When you close your browser |
| CSRF token | Protects forms against cross-site request forgery. | Session |
Because these cookies are essential to provide a service you have requested (logging in and using your account), they do not require consent under UK rules. We do not currently run analytics or marketing cookies; if that changes, we will update this policy and ask for consent where required.
3. Managing cookies
You can delete or block cookies in your browser settings. If you block the strictly-necessary cookies above, you will not be able to log in or use your account.
4. Changes
We may update this policy. The “last updated” date above shows the latest version.
