If you create an account: your email address and, for Google sign-in, your Google account's basic profile. We store your subscription tier and credit balance, and a log of credit transactions (purchases and spends) so we can answer billing questions. We'll also send you a one-time welcome email when you sign up — replying is optional and won't subscribe you to anything further; we don't send any other marketing email.
Using the map sends tile requests to OpenFreeMap (our map data provider), place search queries to Geoapify, and, if you use the satellite/terrain basemaps, tile requests to MapTiler. Like any web host, they see your IP address. We don't sell or share your data with anyone else.
Payments are processed by Stripe. Your card details go directly to Stripe and never touch our servers. We store only your Stripe customer reference.
Account and billing data is stored in Google Firebase (Firestore/ Authentication) in the United States.
We use Firebase Authentication's session storage to keep you signed in. We use Google Analytics to understand how the tool is used (which features get clicked, how many free users go on to subscribe), and Google AdSense to show ads to free-tier users — both set cookies and may use your IP address for approximate location. Subscribing to Map Builder Pro ($5/mo) removes ads. Blocking these in your browser doesn't stop you from using the map.
If you publish a map as a hosted page (a mapbuilder.app/m/… link), we count its traffic in aggregate for the map's owner: total views per day, which shapes get clicked, and the website domain the map was viewed on. These counts set no cookies and store nothing about individual visitors (no IP addresses, no identifiers).
The default map is © OpenFreeMap © OpenMapTiles, data from OpenStreetMap contributors. The Satellite/Terrain basemaps (and the automatic backup basemap used if OpenFreeMap is briefly unreachable) are © MapTiler © OpenStreetMap contributors. Place search is powered by Geoapify © OpenStreetMap contributors.
