Our privacy promise
Fairy Doors is for children, so privacy comes first. Here is everything the app and this website do with your information, in plain English.
No accounts
You don't need an account to look for doors. The app gives each phone a random ID so our server knows requests come from the real app. It isn't linked to your name, your Apple ID or your children.
Your children stay on your phone
Nicknames, fairy looks, stickers and fairy dust are kept on your phone. They are never sent to us. Resetting or deleting a child removes their stickers and fairy dust from the phone. A grown-up can send them to another of your phones as a file, by AirDrop or Messages. It goes straight there and never through us.
Where you are
Your exact position stays on your phone. The heat meter, search circles and hints all work on the phone. To find doors near you, the app sends only your rough area, a square about 1 km across, and nothing during a hunt. If a grown-up turns on warmer and colder nudges, the app keeps using your location on the phone during a hunt while it's locked, for up to an hour, and iOS shows a blue badge while it does. The nudges are made on the phone and nothing is sent.
When you find a door
We record that a door was found, on which day, how many children were there and which hints were used. We don't record where you were, your phone's ID or the time of day, and we can't link your finds together.
We ask first
If anything more is ever needed, like helping fix a door's pin, a grown-up is asked every time, with No as the answer unless you tap Yes. There is no "always" option.
Maps
The app draws its own map from OpenStreetMap data. Map pieces only ever come from us and are kept on your phone, so the map works without signal. The app fetches them for about 2.5 km around you, and if you move the map somewhere else, it asks for the pieces it needs to draw there. Zoomed right out, the app shows how many doors there are in each area, using a list that's the same for everyone. If you zoom in on another town, the app also asks for the doors there. That tells us roughly which area you're looking at, not where you are, and we don't keep it. A grown-up can also download a whole region, with its map and its fairy doors, to hunt there without signal. That tells us only which region was chosen and which large squares of map were fetched, each about 25 km across, and we don't keep that either. Nothing is fetched during a hunt. No map company sees where you are. Walk times are worked out on your phone along the map's paths and never sent anywhere. If a grown-up taps Directions, Apple Maps opens with the door's search circle as the destination, so Apple knows where you're heading.
No tracking, no ads
No ads, no analytics, no third-party code and no social features. Nobody else can see your children or what they have found.
This website
This website has no cookies, no analytics and no third-party code, fonts or scripts. Like any website, our host Cloudflare handles your device's internet address to send you the page; we don't switch on any visitor logs. If you tap a door's chip without the app, the page you see is the same for every door, and the door's secret code in the link is never sent to us.
Who we are
Details of who runs Fairy Doors, and how to get in touch, will be here before the app is released.
