Calculator inputs
Calculations run in your browser. CalcReed does not create user accounts or store calculator inputs in a project database.
Share links
After you submit a calculation or copy its link, field values may be placed in the page URL so you can revisit the same estimate. Anyone who receives that URL can see those values. Do not place sensitive information in calculator fields.
Local device storage
The service worker may cache site files for performance and offline fallback. Calculator URL parameters are excluded from cache keys, and the cache is not a user profile.
If you use “Add to project list”, the saved estimates (calculator name, results and the calculator link with its values) are stored only in your browser under calcreed_project_v1. They are never sent to CalcReed or anyone else, and you can remove them at any time on the Project list page or by clearing your browser data.
Optional analytics
CalcReed uses Google Analytics 4 only after you choose “Allow analytics”. If you reject analytics, the Google Analytics tag is not loaded. The current Measurement ID is G-Y0V728B97P. Page-location data is sent without query strings so calculator values stored in share URLs are not included in the Analytics page URL. Google Signals and advertising personalization are disabled in this implementation. You can change your choice using “Cookie settings” in the footer.
Advertising
No advertising tags are enabled in this build.

Google Analytics data is kept for the retention period set in our Analytics property, and no longer than 14 months. Technical logs are kept only as long as our providers need them for security and reliability.
Your rights
You can ask for access to your data, its correction or deletion, restriction of processing, and you can object to processing. You can withdraw consent at any time without affecting processing carried out before. You also have the right to lodge a complaint with a supervisory authority; in Poland this is the President of the Personal Data Protection Office (UODO).
