Privacy Policy

Last updated: 2 November 2026

TidesMap is a free tide times website. This policy explains, in plain words, what happens to your information when you use it. In short: there are no accounts, no tracking cookies, and we do not sell or share your data.

Who we are

The data controller is TidesMap. You can reach us at hello@tidesmap.com.

What we collect

• Nothing you have to give us. There is no sign-up, login or account, and you never need to enter personal details to use the site.
• Cloudflare Web Analytics. We count visits with Cloudflare Web Analytics. It does not use cookies or local storage and does not follow you across other sites. We only see totals, such as page views, pages visited, referring sites, countries and device types. We cannot identify individual visitors from it.
• Emails you send us. If you write to hello@tidesmap.com, we receive your email address and whatever you include in the message. We use it only to read and reply to you, and we keep it only as long as needed for that.

What stays in your browser

• Favourites and recently viewed stations are saved in your browser’s local storage on your own device. They are never sent to us. You can remove them at any time by clearing this site’s data in your browser settings.
• “Near me” asks your browser for your location only when you press it, and only with your permission. The location is used on the page to find the closest stations and is not sent to us or stored.
• Sunrise, sunset and the moon phase are calculated in your browser.

Services your browser connects to

To show the site, your browser connects to the services below. Like any website, each of them receives your IP address and basic browser information when your browser requests something from it.

• Cloudflare hosts and delivers TidesMap. Cloudflare processes IP addresses and request details to deliver pages and protect the site from abuse. See the Cloudflare privacy policy.
• OpenFreeMap supplies the map tiles when a map is shown. See openfreemap.org. The map software (MapLibre) is served from our own site.
• NOAA CO-OPS (the US National Oceanic and Atmospheric Administration) supplies the latest water temperature and wind readings, which your browser requests directly from NOAA’s public data service. See the NOAA privacy policy.

We do not use advertising networks, social media plugins or web fonts from third parties.

Cookies

TidesMap does not set cookies. See our Cookie Policy for details.

Your rights (UK and EU)

Under the UK GDPR and the EU GDPR you have the right to ask what personal data we hold about you, to have it corrected or deleted, to object to or restrict its use, and to receive a copy of it. In practice the only personal data we may hold is an email you sent us. Our legal basis for handling it is our legitimate interest in replying to you. To use any of these rights, email hello@tidesmap.com. You can also complain to your data protection authority, such as the Information Commissioner’s Office (ICO) in the UK.

Your rights (United States)

If you live in California or another US state with a privacy law, you have the right to know what personal information we collect, to ask us to delete it, and to opt out of its sale or sharing. We do not sell or share personal information, and we do not use it for targeted advertising. To make a request, email hello@tidesmap.com. We will not treat you differently for using these rights.

Children

TidesMap is a general audience site and does not knowingly collect personal information from children.

Changes

If what the site does with data changes, for example if advertising is added, we will update this page first and change the date at the top.
