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.
Google S2 favicon service — company logos use www.google.com/s2/favicons?domain=… to render the company's site icon. Loading the icon makes a request to Google with the domain only; no user identifier is sent by us. If you'd rather opt out, we'd need to stop showing logos — let us know.
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).
