Cookie Policy
Last updated: 3 October 2026
1.What Are Cookies
Cookies are small text files placed on your device by a website when you visit it. They are widely used to make websites work, remember your preferences, and provide information to site owners.
Exaim uses strictly necessary cookies — those that are essential for you to use the platform, such as signing in and maintaining your session — and, only if you agree, analytics cookies that help us understand how the site is used. We ask for your choice on your first visit, and analytics cookies are never set unless you accept them. If you open our support chat from your account menu, our chat provider sets its own cookies to keep that conversation going. We do not use cookies for advertising or for any form of behavioural tracking or profiling.
2.Cookies We Use
Our essential cookies keep you securely signed in, remember your cookie choice, and carry out things you have asked for, such as returning you to the page you were on after signing in. The sign-in cookies are set by Supabase, our authentication and database provider; the rest are set by Exaim. None of them is used for analytics or advertising.
| Cookie | Purpose | Duration |
|---|---|---|
| sb-[ref]-auth-token | Stores your encrypted authentication session so you remain signed in between page loads. The session inside it is renewed every hour. | Up to 400 days, or until you sign out |
| sb-[ref]-auth-token-code-verifier | Temporary PKCE code verifier used during the OAuth sign-in flow. Deleted once sign-in completes. | Until sign-in completes |
| exaim_consent | Remembers whether you accepted analytics cookies, on both www.exaim.ai and app.exaim.ai, so we only ask once. | 6 months |
| exaim_return_to | Remembers the page you were opening when we asked you to sign in or sign up, so we can take you back to it. | 1 hour |
| exaim_course | Remembers the course you were looking at when you signed up, so it is ready for you when you set up your account. | 1 hour |
| exaim_active | A short-lived, signed record that your account was checked and is in good standing, so we do not re-check on every page. | 1 minute |
| learn-last | Remembers the course, topic and tab you last studied, so we can offer to continue where you left off. | 30 days |
| studio-nav | Remembers whether you collapsed the side menu in the student app. | 1 year |
| exaim_impersonate | Exaim staff only: used when our support team views the platform as a user to help with a problem. | 1 hour |
Where is data stored?
The sign-in cookies reference a session token whose underlying data is stored in Supabase's EU data centre (Frankfurt, Germany). The cookie itself contains only an encrypted reference — no personally identifiable information is stored inside the cookie value.
Analytics cookies — only with your consent. If you accept analytics on the cookie banner, we use Google Analytics to understand how visitors use the site — which pages they read and how they arrived — so we can improve it. These cookies are not set unless you accept them, and you can decline with no loss of functionality.
| Cookie | Purpose | Duration |
|---|---|---|
| _ga | Set by Google Analytics to distinguish one visitor from another. Set only after you accept analytics cookies, and deleted if you withdraw consent. | 13 months (400 days) |
| _ga_[id] | Set by Google Analytics to keep track of your session. Set only after you accept analytics cookies, and deleted if you withdraw consent. | 13 months (400 days) |
3.Cookies We Do Not Use
Exaim does not use any of the following:
- Advertising or retargeting cookies
- Third-party social media cookies
- Session-replay or behavioural-profiling cookies (e.g. Hotjar)
- Any analytics cookies before you have given consent
- Support-chat cookies before you open the chat
Our strictly necessary cookies are exempt from consent under UK GDPR and the Privacy and Electronic Communications Regulations (PECR), and we display a notice on your first visit so you are aware of them. Our analytics cookies are not exempt, so we never set them unless you choose "Accept all". Choosing "Essential only" keeps analytics off, and the platform works in exactly the same way.
4.Managing Your Cookies
Change your choice
You can change or withdraw your analytics choice at any time — here, from "Cookie settings" at the foot of every page, or under Privacy in your account settings. Your choice applies to both www.exaim.ai and app.exaim.ai and is kept for 6 months, after which we ask again. Withdrawing consent switches Google Analytics off straight away and deletes its cookies.
You can also control or delete cookies through your browser settings. Most browsers allow you to refuse new cookies, delete existing cookies, or be notified when a cookie is set.
Browser cookie settings
Important
Blocking or deleting the session cookies listed above will prevent you from remaining signed in to Exaim. You will need to sign in again each time you visit.
5.Changes to This Policy
We may update this Cookie Policy from time to time. Any changes will be published on this page with an updated "Last updated" date. If we introduce any non-essential cookies in the future, we will seek your consent before setting them.
