Privacy policy
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.
The app explains why it wants your location before the system asks, and uses it to sort the station list by distance and to centre the map on you. That coordinate never leaves your device. The distance sort and the nearest-station lookup both run on the phone, against a station catalogue the app already has.
You can refuse. The app does not degrade into an error screen — the station list stays searchable by name and region, and the map still lets you drop a pin anywhere.
Find My Tide uses PostHog to keep an anonymous, aggregate record of how the product is used. The website collects anonymous page views — no cookies, no identifier that outlives your visit. The app sends one anonymous, randomly generated install ID, plus which screen you're viewing — and, on a station's detail screen, that station's published ID and name, so we can see which stations are actually used. 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. There is still no advertising, no data broker, and no account.
The app 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. If you dropped a pin, it is the coordinate of the nearest station to that pin, not the pin. 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.
No database of user accounts — there's no account to have. The anonymous usage data described above is the only thing we keep, and it isn't tied to a person.
Your choice of metres or feet, your colour scheme override, and the fact that you have already been asked for location are stored on your own device so the app opens the way you left it. None of them is ever sent anywhere, and deleting the app removes them.
This website sets no cookies.
- 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. It never receives a cookie, a device identifier, or anything else that identifies you.
- 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.
The app is suitable for all ages and collects nothing from anyone, of any age.
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.
