Cookie policy
Last updated 2026-10-10.
What we use
Very little. We do not run advertising cookies and we do not allow third parties to track you across other sites from here.
| Cookie | Purpose | Type | Lifetime |
|---|---|---|---|
fmsc_session | Keeps you logged in. Secure, HttpOnly, SameSite. | Strictly necessary | 30 days, or until logout |
fmsc_csrf | Protects forms against cross-site request forgery. | Strictly necessary | Session |
fmsc-theme | Remembers whether you chose light or dark. Stored in localStorage, not sent to us. | Preference | Until cleared |
Analytics
We use Cloudflare Web Analytics, which is aggregate and cookieless — it does not set a cookie, does not fingerprint you, and does not build a profile. We use it to see which pages are useful and whether the free tools lead anyone to sign up.
Stripe
When you reach a payment page, Stripe may set cookies necessary for payment processing and fraud prevention. That is governed by Stripe's own privacy policy, and it only happens if you go to checkout.
Your choices
The strictly necessary cookies are required for login and form security; without them the logged-in parts of the Service cannot work. You can block or delete cookies in your browser at any time, and you can browse every guide, every county page and every calculator on this site without accepting anything, because none of it requires an account.
