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. Clicking a quick-pick port, or Look up port and then selecting a match, sends the port coordinates and date to sunrise-sunset.org for daylight; a typed lookup also sends the text you typed to Open-Meteo (geocoding-api.open-meteo.com); neither request happens until you click. Clicking Load 7-day port weather & sea state sends the port's coordinates to the shared keyless weather feed at https://utility-live-data.dheerajnamburu.workers.dev, which relays MET Norway forecast data, and to Open-Meteo's marine API (marine-api.open-meteo.com) for wave height; this request happens only when you click that button.
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
The operator has enabled an advertising integration. No ad request is made until its consent-management integration signals allowed consent. The operator must publish vendor-specific notices, regional choices, withdrawal controls, and retention details before production use. Global Privacy Control suppresses the built-in ad loader. Google Analytics is configured and consent-gated.
Operator contact and limitations
Contact the operator at dheerajnamburu@gmail.com. Do not send sensitive source files without an agreed secure process.
