Privacy Policy

This page explains the current Phase A version of Guilloché Dial Studio: a free, offline watch-dial design tool for the web, iPhone, and iPad.

Summary: Data Not Collected

Guilloché Dial Studio's current Phase A app does not collect personal data. There are no accounts, logins, in-app purchases, ads, analytics, tracking, or third-party SDKs that collect data.

Local-only designs and settings

Your dial designs, names, timestamps, geometry, colors, machine profile, cut settings, and first-run preferences are stored locally in browser storage or on your device. Guilloché Dial Studio does not automatically upload them.

Exports such as SVG, DXF, PNG, STL, STEP, or similar files are created locally and are shared only when you choose to save, share, or send them.

User-initiated network activity

Guilloché Dial Studio only makes outbound requests when you choose to start them:

  • Vendor links: You may open fabrication vendor websites such as OSH Cut, SendCutSend, xTool, or Bambu Lab in your browser or an in-app Safari view. Those third-party sites are not controlled by Guilloché Dial Studio and have their own privacy policies.

Fonts and app assets are bundled with Guilloché Dial Studio.

No tracking, analytics, or advertising

Guilloché Dial Studio does not use IDFA, cross-app tracking, advertising SDKs, analytics SDKs, crash-reporting SDKs, remote config, or beacons in the current Phase A app.

Website hosting

The public website is hosted on Cloudflare Pages. Hosting providers may process basic request information, such as IP address, user agent, timestamps, and request paths, for security and operations. Guilloché Dial Studio does not use this information for advertising or tracking.

Contact and support email

If you contact support by email, your email provider sends your email address and whatever information you choose to include. Guilloché Dial Studio uses support messages only to respond to your request.

Children's privacy

Guilloché Dial Studio is not directed to children under 13 and is not intended for the App Store Kids Category. Guilloché Dial Studio does not knowingly collect personal data from children.

Changes to this policy

This policy should be updated before Guilloché Dial Studio adds accounts, payments, cloud sync, analytics, crash reporting, feedback SDKs, or any other feature that changes data practices.
