Calculator and project data
Calculations run in your browser. Dimensions, quantities, product identifiers, project names and stock are not sent to an analytics service by this application. When you add an estimate to the material list, it is stored on this device using local storage. There is no account or cloud synchronization. Full project JSON backups can be imported on this device after validation and confirmation; the file is read locally and is not uploaded.
You can remove saved estimates in the material list. Clear this site’s browser data to remove all local records and stock. Downloads remain on your device until you delete them. Printing or sharing a downloaded file is under your control.
Analytics and advertising
Sumsible currently has no connected analytics collector or advertising scripts. It creates local browser events for tool use, valid calculations, additions, list generation, printing, downloading and navigation. Those events contain only a fixed event name and calculator identifier; the application does not transmit them. A future collector requires a separate configuration and privacy review.
Hosting and external references
The hosting provider receives the ordinary information needed to deliver a web page, such as network address and request details, under its own policies. This application does not claim that hosting is anonymous or log-free. Reference links lead to independent sites with their own policies; no project inputs are included in those links.
Changes to this policy
If analytics or advertising is added, this page will be updated to describe what is collected, which providers receive it and the choices available to visitors before those services are enabled. Using Sumsible does not imply advertising consent.
