Local-first by design
Battlemap Slicer stores your dungeon projects and map images in your browser using IndexedDB. We do not upload your maps to our servers in this version of the app.
What stays on your device
Dungeon names, calibration settings, room polygons, and map image files are kept locally. Clearing your browser data or uninstalling the app will remove saved dungeons.
Accounts and sign-in
Signing in with Google is required to use the app. We store your email address, display name, and license status in Firebase (Google Cloud) to operate licensing. We never receive your Google password, and your map images are never uploaded.
Purchases
One-time purchases are processed by Lemon Squeezy, our merchant of record. Lemon Squeezy handles payment details under its own privacy policy; we receive only your order metadata (email, order number) to activate your license. Patreon-based access checks your membership tier through the FutureHax catalog using the email you sign in with.
