Cookie Notice
Tidal AI uses only the cookies and browser storage it needs to work. No analytics, no advertising, no tracking across sites.
The short version
We use strictly necessary cookies only: to keep you signed in (to one account, or to several if you add more than one on the same browser) and to remember which workspace you are in. Because they are essential to the service you asked for, the law (UK PECR, the EU ePrivacy Directive) doesn't require us to ask for consent, so you won't see a cookie banner. We don't use analytics, advertising or social media cookies, and nothing tracks you across other websites.
Cookies we set
| Name | Purpose | Set by | Lasts |
|---|---|---|---|
tidal.session_token (or __Secure-tidal.session_token on secure connections) | Keeps you signed in. Signed, HttpOnly (scripts can't read it), SameSite=Lax | Our API, when you sign in | 30 days after you last used Tidal AI, or until you sign out |
tidal.acct_… (with a __Host- or __Secure- prefix on secure connections), one per account you are signed in to on this browser, up to five | Keeps each account signed in so you can switch between them without signing in again. Each holds that account's own signed session value, never anything we can read about you. Signed, HttpOnly, SameSite=Lax | Our API, when you sign in or add an account | 30 days after you last used that account, or until you sign out of it |
tidal.accts (with a __Host- or __Secure- prefix on secure connections) | Remembers which accounts this browser has been signed in to (their names and email addresses, and the workspace each was last in), so an account that has signed out can be shown as "Sign in again" and switching returns you to where you were. Signed, HttpOnly, SameSite=Lax | Our API, when you sign in, switch or sign out | 180 days, or until you sign out of all accounts |
tidal_ws | Remembers which workspace (personal or organization) you're working in | Our API | Until you sign out of the account (it is kept per account when you switch) |
tidal_uid | Development only: lets a developer try the product as different test people. Never set on the live service | Our API, in development builds | Session |
Google and GitHub may set their own cookies on their own sites if you sign in with them; those are covered by their policies.
Other storage in your browser
The app also keeps a few settings in your browser's local storage, such as layout, graphics quality, sound, your cookie choices and a random id used only to record a "do not sell or share" request if you make one while signed out. This never leaves your device except for that request, and is not used to track you.
Your choices
You can delete cookies in your browser at any time; you will be signed out. If we ever add optional cookies (for example analytics), we will ask first, they will stay off unless you agree, and you can change your mind here:
Your choices in this browser
Strictly necessary: always on (they keep you signed in and remember your workspace).
We treat a Global Privacy Control signal from your browser as a refusal of any optional tracking.
