What we store

Your floorplans, walls, and access-point placements are saved entirely in your browser's localStorage. Nothing is uploaded to our servers.

What we collect

We log anonymous usage counters (number of renders, exports, and saves) plus the request IP, used only for aggregate usage stats and abuse prevention. IP addresses are never published or shared. We do not log file contents, floorplan images, or any other personally identifiable information.

Cookies

The free tier sets no cookies. When you activate Pro, we set a single HTTP-only, HMAC-signed cookie that links your purchase email to your Pro access so the editor knows to unlock Pro features. It contains no tracking data and is not shared with third parties.

Payments

Purchases are processed by Stripe. We store your purchase email and a Stripe reference in order to grant and verify Pro access; we never receive or store your card details. Stripe processes the payment and emails your receipt.

Analytics

We use Plausible Analytics, a privacy-respecting alternative to Google Analytics. No personal data is collected.
