Privacy & data choices
Use the tool without an account. Keep control of the information you enter.
Local processing
The app does not send form inputs, CSV files, JSON plans, G-code, or results to an application server. Calculations run on your device. Static hosting providers can still log normal page requests, IP addresses, and technical request metadata under their own policies. Source links lead to external websites.
Optional saving
Clicking Save on this browser explicitly stores the plan in localStorage. It is not encrypted, is not backed up, and is visible to other people using the same browser profile. Delete individual plans or all plans in Saved plans. Clearing browser storage also removes these records. Downloaded exports are separate files you manage yourself.
Sharing and sensitive information
Share fields places only scalar inputs in the URL fragment. Imported record tables are excluded. Anyone with the full link can read those fields. Do not include confidential information in a shared link. JSON exports contain the entire plan and should be handled as private files.
Ads and analytics
Advertising and analytics are disabled in this build. No advertising cookies, third-party fonts, remote analytics scripts, or behavioral tracking scripts are loaded by this app.
Operator contact and limitations
The operator has not configured a private contact address. Use the linked source repository only for non-sensitive bug reports. A production operator must configure an appropriate contact channel and review this policy for the chosen host and any added integrations.
