Your calculations and saved plans
Calculator inputs are processed in your browser. We do not operate a server database for your projects. Choosing “Save project” stores the project name, inputs and display color in this browser’s local storage. Results are recalculated with the current formulas when you open or compare a saved plan. Saved plans are not automatically synchronized across devices. The cut-list planner has a separate single-plan browser backup with Restore and Remove controls. Sending a wall cut list to that planner temporarily stores the piece list and stock inputs in session storage and removes them after a successful import. The storage candidate comparison has one separate device backup with Restore and Remove controls; it is not listed in My projects. Articles search runs in your browser, and its query is included in the URL. Shower checklists are not saved; print them before leaving. Appliance care records are saved only when you choose Save, in a separate browser-local list. They include the fields you enter and can be exported as JSON or CSV, imported, or removed from the care-record tool. They are not synchronized to an account or sent to a site database. Obstruction boxes and worksheet notes are not saved by the site; export or print them before leaving.
You can delete individual saved projects or clear all projects on the My projects page. Browser controls can also remove this storage. CSV downloads remain on your device until you delete them yourself.
Sharing a plan
“Copy plan link” puts your tool settings into the URL query string. Anyone with the link can read those settings. URLs may appear in browser history and hosting access logs. Do not enter personal or confidential information into a plan name or shared link.
Cookies, analytics and advertising
The application does not install analytics trackers, advertising tags, or marketing cookies in this version. The hosting provider may process technical information needed to serve and secure the site, such as IP address, request URL and browser metadata. These tools are publicly accessible without a site account.
External links
Our guides link to manufacturer and public-agency resources. Those sites have their own privacy practices. Clicking an external reference takes you to a different service.
Future changes
If advertising, analytics, a contact form or other collection is added, this notice must be updated to describe the actual processing and any applicable consent choices before that feature is used.
