Privacy

TideTime has no user accounts, sets no tracking cookies, and runs no analytics that identify you. Your settings live in the page URL, not on our servers.

Third-party requests

To work, your browser (or our server on your behalf) contacts these services:

• NOAA CO-OPS — tide predictions for the station you select (via our cached API).
• OpenStreetMap Nominatim — geocoding the text you type in the search box; the query is sent to OSM.
• Map tiles (Leaflet/OpenStreetMap) — tile requests reveal the map area you view.
• Google Calendar — only when you click “Subscribe,” the subscription URL is opened on google.com.

We don’t sell data because we don’t collect it. Each third party has its own privacy policy.
