Privacy Policy
Last updated 27 October 2026
In short:
- Your maps stay on your devices and in your own iCloud Drive. We can't see them.
- Only maps you choose to share are kept on our server, so the people you send the link to can open them.
- To share, you sign in with Apple or Google. We keep your name, your email address and the maps you share.
- The apps send anonymous usage counts, such as how often maps are opened, and the country they came from, so we know what to improve. They never include what's in your maps or who you are, and you can turn them off in Settings.
- We don't sell your data, show ads, or track you across other companies' apps and websites.
- You can delete your account in the app at any time, and the maps you shared go with it.
This policy covers the Mai Map apps for Mac, iPad and iPhone, and the website at maimap.app, including shared maps opened there. "Mai Map", "we" and "us" mean the people who make Mai Map.
Maps you don't share
Maps you make in Mai Map are files on your device, or in your iCloud Drive if you keep them there. iCloud is Apple's service, covered by Apple's privacy policy. We never receive these maps.
Your account
You need an account only to share maps, or to edit a map someone shared with you. You sign in with Apple or Google; Mai Map has no passwords of its own. When you sign in, we receive and keep:
- an identifier for your Apple ID or Google account, which tells us it's you next time;
- your name, as Apple or Google gives it (you can change it with them);
- your email address, if Apple or Google gives one. With Sign in with Apple you can choose to hide your email, and Apple gives us a private relay address instead.
Signing in also makes a session, so you stay signed in. The app keeps it in your device's keychain, and the website in your browser's local storage. We store only a scrambled form of it (a hash).
Maps you share
When you share a map, a copy goes to our server, and changes made to it while it's shared go there too, so that everyone with the link sees the latest version.
- Anyone with the link can see the map and its notes, and download a copy.
- People who accept your invite can edit it. You see their names in the app.
- If you edit a map someone else shared, your edits become part of their map.
You can stop a link, or replace it with a new one, at any time; the old link stops working for everyone. The copy on our server is deleted when you delete your account.
Usage counts
The apps send anonymous counts of what happens in them, such as "the app was opened", "a map was opened", "a map was shared" or "an import finished". They're on unless you turn them off. A count says which kind of event happened, plus plain facts such as the file format imported, a rough map size ("10 to 49 topics"), the app version, the kind of device, and the country it came from.
Each install is told apart by a random number made on your device and scrambled before it's sent, so we can see things like how many people come back to Mai Map after a few weeks, how many bring in maps from other apps or share one, and how often Mai Map crashes. It never includes what's in your maps, file names, your name, email or account, or anything else that identifies you, and we look at the counts only in total, never person by person.
The counts go to PostHog, an analytics service, and are kept in its European Union data centre. They're sent as anonymous events: PostHog makes no profile of you from them.
Country. As a count arrives, PostHog uses the internet address it came from to work out the country (and so the continent). It keeps only that: no city, region, postal code or coordinates. It then discards the address; your internet address is never stored with the counts.
You can turn the counts off at any time in Mai Map's Settings, under Privacy; nothing is sent after that.
Problem reports
If Mai Map crashes, your device's system gives Mai Map a report the next time it opens. The report stays on your device unless you choose to share it from Settings ▸ Problem Reports. Only an anonymous count that a crash happened, with its type, is included in the usage counts above. If you test Mai Map through Apple's TestFlight, Apple collects crash logs and feedback under its own terms.
The website
When you visit maimap.app or open a shared map, our hosting provider handles your request and may keep short-lived records of it, such as your IP address and browser type, to deliver the page and to keep the service working and secure. The website uses no cookies for tracking and no advertising. If you choose to sign in on the website, it loads Apple's or Google's sign-in from them, under their own privacy policies.
Who handles your data for us
- Cloudflare runs our server and stores accounts and shared maps.
- Apple and Google sign you in, when you choose them.
- PostHog receives the anonymous usage counts, works out each one's country, and keeps them in the EU.
They process data only to provide their service to us. Cloudflare's network is worldwide, so your data may be processed in countries other than yours.
Deleting your data
In the app, go to Settings ▸ Sharing ▸ Delete Account. This deletes your account, your sessions, the maps you shared from our server (their links stop working for everyone), and your ability to edit maps others shared. Copies of maps on your devices, and on other people's, aren't touched. You can also email us to ask what we hold about you, to correct it, or to delete it.
Children
Mai Map isn't directed at children under 13, and we don't knowingly collect their personal information.
Changes
If this policy changes, we'll update this page and the date at the top. If a change affects what we collect, we'll say so in the app before it applies.
