Cookie Policy
Last updated October 12, 2026
This policy describes the cookies and similar technologies used on Firefly. Our Privacy Policy explains how we handle the information they collect.
About cookies
Cookies are small files that a website stores in your browser. Local storage and session storage work in a similar way; session storage is cleared when you close the tab. In this policy, “cookies” covers all of these technologies.
We use two kinds. Necessary cookies make the Service work and keep it secure, so they are always on. Analytics cookies help us understand how the Service is used so we can improve it. We don’t use advertising cookies.
Necessary cookies
| Cookie | Purpose | Duration |
|---|---|---|
better-auth.session_token | Keeps you signed in | 7 days, renewed while you use the Service |
better-auth.state, better-auth.oauth_state | Secure sign-in with Google or Apple | Up to 10 minutes |
ff_consent | Remembers your cookie choice | 12 months |
theme (local storage) | Remembers whether you chose light or dark mode | Until you clear it |
| Cloudflare Turnstile | Protects the sign-up and password reset forms from bots | Up to 1 hour |
| Sign-up security check | Generates a device identifier when you sign up, which we store with your account to prevent fraud and abuse | Kept with your account |
Analytics cookies
In the European Economic Area, the UK and Switzerland, these cookies are off unless you allow them. Elsewhere they are on unless you turn them off.
| Cookie | Purpose | Duration |
|---|---|---|
ff_aid | A random identifier that connects your visits to the Service | 13 months |
ff_attr | Records the page and campaign that brought you to the Service | 90 days |
ff_sid (session storage) | Groups the pages you view during one visit | Until you close the tab |
When you turn analytics off, we delete these cookies from your browser.
Cookies set by other companies
Creem’s checkout and the Google and Apple sign-in pages are run by those companies on their own websites and use their own cookies under their own policies. We don’t load third-party advertising or analytics scripts.
Your choices
You can allow or turn off analytics cookies at any time using Cookie settings at the bottom of every page. If your browser sends a Global Privacy Control signal, analytics stays off. You can also block or delete cookies in your browser settings, although the Service will not work properly without necessary cookies.
Changes to this policy
We will update this policy and its date when the cookies we use change. If we add a new purpose that needs your consent, we will ask again.
