Privacy policy

Your models and settings

Models are generated in your browser. Your dimensions and the STL files you create are never uploaded to us and we keep no copy. Settings live in the page address and in your browser only.

Anonymous statistics

We count page views and a few actions (generate, download, checkout click) using the PostHog capture API. Each event carries a random identifier stored in your browser (local storage, not a cookie), the page address, the referrer and any UTM tags. We do not collect your name, email or the contents of your designs. Like any web request, the analytics call reaches PostHog with your IP address, which PostHog may use to estimate an approximate location. We never link it to your name or email. If your browser sends Do Not Track or Global Privacy Control, no event is sent at all. Clearing site data resets the identifier.

Payments

Pro purchases are handled by Stripe, which collects your card and email under its own privacy policy. We never see your card number. To unlock Pro, the site asks Stripe whether your checkout session was paid; we store nothing about it except a flag in your browser.

Retention

We store no user files. Analytics events are kept in PostHog under its standard data retention and are never sold or used for advertising. Stripe keeps payment records as required by law.

Your choices

Turn on Do Not Track or Global Privacy Control in your browser to disable all statistics. For access or deletion of any record tied to your purchase, email matt@detroitwebagent.com.
