What we store in your browser

Information stored in your browser
What	Why	How long
Sign-in session (browser storage)	Keeps you signed in. The access part is short-lived and renewed automatically while you use the site.	Until you sign out, after 30 minutes without activity, or at most 7 days
Preferences: last portal and page, map layers, light or dark theme	So the site opens where you left off	Until you clear your browser data
Certificate order link	Lets you download a certificate you paid for without an account	30 days
Cloudflare security check (on sign-in, sign-up, password reset and card payment only)	Tells people from bots to stop password guessing and fake accounts	Set by Cloudflare for the check itself

These are strictly necessary for the service to work, so they don't need your consent. You can clear them at any time in your browser settings; you will then be signed out.

Outside services a page loads

To show the website, your browser connects to: our hosting provider (Netlify); our database and sign-in service (Supabase); OpenStreetMap for map images (and Esri, only if you choose satellite imagery on the map); Cloudflare for the security check on sign-in forms and card payments; and Stripe when you choose to pay by card. Our typefaces are served from our own website, so no font service sees your visit. Each of these sees your IP address and browser type when it delivers content, and handles them under its own privacy policy. None of them receives your account details from us except Stripe, when you pay. See the privacy notice.
