Marin Tides

Privacy

What we collect

Nothing personal unless you sign up for alerts. There are no accounts and no advertising trackers. Tide times are worked out in your browser from data delivered with the page.

Email alerts

If you sign up for tide alerts, we store your email address, the spots you picked and the alerts you want. We use them only to send those alerts, through our email provider Resend. We never sell or share your address. Every email has a one-click unsubscribe link, and unsubscribing stops all email.

Analytics

We use Clicky to count visits and see which pages people read. Cookies are turned off, so nothing is stored on your device, and we never sell or share the data.

Maps

Station maps load tiles from OpenStreetMap when you scroll to them. OpenStreetMap sees your IP address, as with any web request.
