Privacy

Seafarer Index does not use analytics, trackers, or third-party scripts that identify you. There are no advertising cookies. We do not attempt to fingerprint your device.

What we store

• Anonymous visitors: nothing on our servers. The two cookies we set client-side are the theme preference (theme) and low-data mode (ldm) — both optional, both first-party, both opt-in via the toggles in the header.
• Forum members: the email you register with (Supabase Auth — used for sign-in and password reset only) and the handle / optional rank / optional nationality / optional bio you choose. You can delete your account from /account; deletion removes your auth row, profile, and any newsletter subscription.
• Newsletter subscribers: email address and a confirmation token. Every newsletter contains an unsubscribe link with a unique token; clicking it removes your row.

Third-party services on page

• OpenStreetMap — port and seafarer-centre detail pages embed an OSM minimap via an iframe to openstreetmap.org/export/embed.html. OpenStreetMap may log the IP that loads the iframe (per their privacy policy). No personal data is transmitted by us.
• flagcdn.com — flag images on flag-state pages.
• Resend — auth and newsletter emails are sent through Resend (smtp.resend.com). Open-tracking pixels are disabled. Click-tracked links are disabled.
• Supabase — Postgres + Auth provider. Forum posts and account data live there. Hosting region: Singapore (ap-southeast-1).

Cookies

First-party only: theme (light/dark), ldm (low-data mode), Supabase auth cookies if you sign in. No tracking cookies, no advertising cookies, no third-party cookies. Browser Do Not Track is respected by virtue of us not having anything to track.

Your rights

• Access: sign in to /account to see what we have on you.
• Delete: the "Delete account" button on /account removes everything in one click. Newsletter unsubscribes are one-click via every email.
• Export: not available via the UI yet — email [email protected] and we'll dump your forum posts + profile within 30 days.
