Calculator inputs and results stay in your browser. No advertising networks are embedded. Cloudflare supplies hosting, security and web performance analytics; its analytics beacon can collect page-view and performance metrics. Report-project files and explicit device saves remain on your device. Purchase handling keeps minimal server-side access records and a keyed email lookup; it does not receive your scenario figures or business branding. Free calculator data is not saved automatically. In the report builder, Save on this device and checkout explicitly preserve a local project; downloadable project files can move it between devices. Email recovery restores purchases, not unsaved project data.
Printing or saving a PDF uses your browser and device. Files you save are under your control. Following a source link opens a third-party website subject to that site’s policies.
Hosting and purchase preparation
Before live sales, the owner must finalize customer refund/support terms and approve the server-record retention policy. Temporary session/recovery credentials expire automatically. Cloudflare hosts this website and processes web requests. The application uses essential session cookies and access records for report-project access; it does not send your scenario figures or business branding to its purchase server. Paid checkout and purchase-recovery email are not yet active. This page will be updated when those services are enabled.
