Last updated 22 September 2026
Find My Tide collects nothing that identifies you. There is no account to create, no advertising, and no third-party SDK beyond the one minimal, anonymous analytics tool described below.
Your location
On this website, “Near me” asks the browser for a coordinate and uses it to sort the station list by distance. That coordinate stays in the browser: the station catalogue is downloaded to your device and the distance sort runs there, so it is never sent to us.
The app behaves the same way, and explains why it wants your location before the system asks. You can refuse on either. Search and the map both work without it — you simply do not get distances.
Usage analytics
Find My Tide uses PostHog to keep an anonymous, aggregate record of how the product is used. The website collects one anonymous, randomly generated ID that your browser keeps for this site, plus which screen you're viewing, and whether you're reading heights in metres or feet — and, when you open a station or star it as a favourite, that station's published ID, name and region, so we can see which stations are actually used, and, when you follow one of our links to the App Store or Google Play, which of the two it was and where on the page you tapped it. None of it is linked to your identity, none of it is a device identifier like an advertising ID, and none of it is shared for advertising. The ID exists so that one person coming back counts as one person rather than two. It is not a cookie, and clearing this site's data in your browser deletes it — a later visit simply starts a new one. In Europe and the UK we ask before keeping it at all; anywhere else, the switch further down this page turns it off. The app sends one anonymous, randomly generated install ID, plus which screen you're viewing, and whether you're reading heights in metres or feet — and, when you open a station or star it as a favourite, that station's published ID, name and region, so we can see which stations are actually used, and which version of the app you are running — the build you installed, and whether an over-the-air update has replaced its code since — so we can tell a release that reached people from one that did not, and spot an update that had to be rolled back, and when you installed the app — the exact time, not just the day — so we can see whether people who install it go on using it. None of it is linked to your identity, none of it is a device identifier like an advertising ID, and none of it is shared for advertising. Both also send your approximate country and device type. Our hosting provider, Cloudflare, keeps a log of the requests made to our server for a few days — what was asked for, including the published position of the station whose weather was shown, and technical details about where the request came from — so we can keep the service running. We do not use it for analytics. There is still no advertising, no data broker, and no account.
What our server does see
Find My Tide talks to one server we run, at api.findmytide.com, for three things: the station catalogue, tide predictions for Canadian stations, and current weather.
The weather request carries a coordinate — the published coordinate of the tide station you are looking at, taken from the public catalogue, not a reading from your device. These are fixed, public locations; thousands of people request the same handful of them.
Like any web server, ours processes the IP address your request arrives from in order to answer it. We do not log requests to build a profile, we do not join them to anything, and there is no identifier in a request that would let us do so.
AI assistants
When an AI assistant connects to our MCP server, we record that a session started and the name and version the assistant gives for itself. For each question it asks, we record which tool it used, whether that worked, and which station it was about. That goes to PostHog, with the approximate country the request came from, under a random ID that lasts only for that session. What the assistant sends to search with — a place name or a position — is used to answer and is not recorded, and your conversation never reaches us. This applies only if you connect an assistant to Find My Tide.
What we store about you
No database of user accounts — there is no account to have. The anonymous usage data described above is the only thing we keep, and it is not tied to a person.
Your choice of metres or feet and your colour scheme override are stored in your own browser or on your own device so the product opens the way you left it. The colour scheme stays there and is never sent anywhere. The unit is part of the anonymous usage data described above — we start you in the one your region reads tides in, and the only way to know whether that was right is to see which one people end up reading.
Stored alongside them is the random analytics ID described above. It is the only thing we keep that lasts longer than a visit, and all it does is let us count one person twice on two days rather than as two people. You can end it at any time by clearing this site’s data in your browser; nothing else about the site changes if you do, and a later visit starts a fresh one. If your browser refuses storage, we keep no ID at all and the visit is simply counted and forgotten.
This website still sets no cookies.
Who else is involved
- Cloudflare hosts our server and this site, and processes requests as our infrastructure provider.
- Open-Meteo supplies weather. Our server calls them with the station coordinate; your device never contacts them, and they never see your IP address.
- PostHog processes the anonymous, aggregate usage counts described above, on our behalf. What it receives is the random ID described above and the activity attached to it — never a cookie, never an advertising or device identifier your phone or browser hands out to anyone else, and never a name, an email or an account, because there is no account here to have one.
- Apple and Google distribute the app, and report their own aggregate install and crash statistics to us. That is their collection under their policies, not ours — we cannot identify you from it.
There is still no advertising network.
Children
Find My Tide is suitable for all ages and collects nothing from anyone, of any age.
Changes
If this policy changes, the date at the top changes with it. A change that affects what leaves your device would come with an app update, not a quiet edit here.
