Privacy policy

Last updated: September 26, 2026

1. Information we collect

To understand and improve how the service is used, we use analytics tools (Cloudflare Web Analytics and PostHog). They record page views, features used (cutting, gluing, opening nets, etc.), browser and device type, approximate region, and referrer.

These tools are configured without cookies, and we do not collect names, e-mail addresses or other personally identifying information.

2. Your shapes

Shapes are computed entirely in your browser. A share link contains the shape data after the “#”, which browsers do not send to the server.

3. Purpose

The information is used only to improve the service, investigate problems, and compile usage statistics.

4. Third parties

We do not provide this information to third parties except as required by law. Analytics providers handle data under their own privacy policies.

5. Changes

We may update this policy and will publish changes on this page.

6. Contact
