Cookie Policy
Last updated: 4 March 2026
This Cookie Policy explains how Fernly Digital Services (“Fernly”, “we”, “us”) uses cookies and similar technologies when you visit our website or use our platform. It should be read alongside our Privacy Policy.
1. What are cookies?
Cookies are small text files placed on your device by websites you visit. They are widely used to make websites work, or work more efficiently, and to provide information to the website owner. Cookies set by the website operator are called “first-party cookies”. Cookies set by parties other than the website operator are called “third-party cookies”.
2. How we use cookies
Fernly uses essential cookies only. These are strictly necessary for the platform to function — without them, core features such as signing in and navigating your dashboard would not work.
We do not use advertising cookies, tracking cookies, or third-party analytics cookies. Under UK GDPR and the Privacy and Electronic Communications Regulations (PECR), strictly necessary cookies are exempt from the requirement to obtain prior consent, though we are required to inform you of their use.
3. Cookies we set
| Cookie name | Purpose | Duration | Type |
|---|---|---|---|
| next-auth.session-token | Keeps you signed in to your Fernly account. Contains an encrypted JWT with your session data. | 30 days | Essential |
| __Host-next-auth.csrf-token | Protects against cross-site request forgery (CSRF) attacks on authentication endpoints. | Session | Essential |
| next-auth.callback-url | Remembers where to redirect you after signing in. | Session | Essential |
| cookie-consent | Records that you have acknowledged this cookie notice so we do not show it again. | 1 year | Essential |
* On production, the session token cookie name is prefixed with __Secure- and transmitted over HTTPS only.
4. How to control cookies
You can control or delete cookies through your browser settings. The links below explain how to manage cookies in the most common browsers:
Please be aware that blocking or deleting essential cookies will prevent you from signing in and using the Fernly platform. Session cookies and CSRF cookies are required for the service to function.
5. Changes to this policy
We may update this Cookie Policy from time to time. Any changes will be posted on this page with an updated “Last updated” date. We encourage you to review this policy periodically.
