Privacy
The short version: Sleep Map has no analytics, no advertising and no tracking, and we run no server that holds anything about you. Your sleep history and map stay on your phone. You sign in with Apple; the app keeps only Apple’s anonymous identifier for you, on your phone, and never sends it anywhere. The app uses the network to search Apple Maps for your hometown and to download public card images and content updates. If you join a Circle, a name you choose and the places you have claimed are shared through your own iCloud with the people in that Circle — and with nobody else, including us.
What is collected
We collect nothing. Sleep Map has no analytics, no advertising, no third-party SDKs, and no tracking of any kind.
Sleep Map asks you to sign in with Apple. It requests no name and no email; Apple gives the app a random identifier that means nothing outside Sleep Map, and the app keeps it in your phone’s Keychain so it can check the sign-in is still valid. It never leaves your phone and we never see it. Settings › Account › Delete account erases your map, nights, settings and Circle membership from your phone and signs you out.
There is no server of ours holding your sleep history, hometown, or map, and the app sends none of that information to us. Requests for public card images and content updates go to our asset host, but contain no account, sleep data, claimed territory, or app-created identifier.
Circles are the one place information leaves your phone, and it goes to the people you invited rather than to us. That is described in full below.
What is stored, and where
Everything the app knows lives in its own storage on your device:
- Your hometown, and the target bedtime and wake time you set
- A record of each night — when you started, when you woke, whether you kept it
- The places you have claimed
- A few settings, such as whether Apple Health is switched on
None of it is ever sent to us, and none of it is used for anything but drawing your own map. Deleting the app deletes all of it. There is no backup on our side to delete, because there is no account or user-data server on our side. Hometown searches and requests for public card images and content updates use the network as described below, but none of the data in this list travels with those requests.
Circles
A Circle is a private group of up to sixteen people who grow one map together. It is entirely optional, and if you never start or join one, nothing in this section applies to you and nothing ever leaves your phone.
When you are in a Circle, your device publishes exactly two things, and only these:
- The display name you type for yourself, and the colour you pick
- The places you have claimed — which map areas, and the date and place of your most recent claim
What is never published: your sleep times, how long you slept, any Apple Health data, and any night you missed. A Circle shows successes only. There is no field for a missed night, so a broken streak is simply silence rather than something other people are told about.
This travels over Apple’s iCloud, using a shared area inside your own iCloud account that only the members of your Circle can read. It does not pass through any server of ours, and we cannot see it. Apple’s handling of it is covered by Apple’s privacy policy.
Anyone holding your Circle’s join code or invite link can join it, so share those the way you would share the address of a private gathering. You can remove a member, and you can leave a Circle at any time — leaving deletes the information you published to it. Leaving never affects your own map: the places you have claimed are yours, kept on your device, and no Circle can take them away.
Apple Health
Sleep Map can read sleep analysis samples from Apple Health, and only that category. It is used for one purpose: to work out when you actually fell asleep and woke, so a night can be confirmed without relying on you putting the phone down and picking it up.
It is optional. If you decline the permission, or never turn it on, the app works completely — it falls back to the manual “phone down at bedtime, pick it up in the morning” flow, and no feature is withheld.
Health data is read on your device, used there, and never transmitted, shared, sold, or used for advertising or marketing. Sleep Map does not write anything to Apple Health.
You can withdraw access at any time in Settings › Health › Data Access & Devices › Sleep Map, or in Settings › Privacy & Security › Health. The app keeps working; it goes back to the manual flow.
Searching for your hometown
When you pick your hometown, the app searches for it using Apple Maps(MapKit, built into iOS). What you type in that field is sent to Apple’s mapping service to return matching places.
That search is handled by Apple under Apple’s privacy policy. We never see it, never store it, and never receive the result. The app does not ask for your device’s location — it has no location permission at all, so your hometown is only ever a place you typed, not somewhere you were detected.
Once your hometown is set, stories, the map, and your progress work without a connection. An uncached photograph may still need the network; the card uses its built-in artwork when that image is unavailable.
Notifications
If you allow them, Sleep Map can remind you when your bedtime is approaching and prompt you in the morning. These are scheduled on your device from the times you chose. Nothing is sent from anywhere, and you can turn them off in iOS Settings.
Photographs and stories
The place photographs and the text they are drawn from come from Wikimedia Commons and Wikipedia, used under their licenses, with the photographer and license shown beside each image in the app. Photographs download from our asset host, assets.sunlitgamestudio.com, as you reach them and are cached on your device. The request identifies the public image URL and carries ordinary connection information such as an IP address; it does not include your sleep history, map progress, hometown, or an account identifier. The app also checks for signed updates to its stories, translations, place names and image catalogs. These requests identify the public content package and the app’s content baseline, with the same ordinary connection information, and contain no account identifier, sleep history, hometown or map progress. Downloaded content is stored on your device; bundled stories remain available offline if an update cannot be downloaded.
Children
Sleep Map collects no personal information from anyone, of any age, including children under 13. Signing in with Apple shares nothing with us, and there is nothing to submit.
Changes
If this policy changes, the revised version will be posted here with a new effective date. Sleep Map will continue to describe its network use and data practices plainly.
