What browser storage does
Cookies and browser storage can keep information on your device between interactions. Calcr uses them for specific functions rather than to store a public visitor account.
| Category | Purpose | What clearing it changes |
|---|---|---|
| Theme preference | Remember the selected appearance | The theme returns to its default or system preference |
| Language preference | Remember a language choice where available | The site may choose its default language again |
| Local game records | Keep best results in this browser | Local records can be lost |
| Privacy choices | Remember optional-service choices | A choice may need to be made again |
| Administrator session | Authenticate authorized administrators | The administrator may need to sign in again |
| Optional analytics cookies | Let Google Analytics associate visits and events with this browser after permission | Analytics browser/session identifiers can reset; the separately stored consent choice may remain |
Scientific calculation history stays in the current session rather than a synced account history. Calculator inputs and results are not included in analytics events.
Optional services and your choices
On your first visit, Google Analytics stays blocked until you choose Allow analytics. Choosing Reject optional services keeps it blocked. After permission, Google Analytics can write analytics cookies and use browser/session identifiers to associate visits and events. Advertising remains off. Calculators and games work when analytics is rejected or unavailable.
The application sends fixed published page addresses without the raw query string or fragment, a fixed page title and a blank page-referrer field. It does not include raw calculator inputs or results in analytics events. Google still receives the technical information needed for its network requests; see Google's privacy policy.
Open Privacy settings in the footer to change your choice. A saved permission can apply on later visits to eligible pages. Withdrawing stops subsequent analytics events from the Calcr application; it does not automatically delete existing analytics cookies or data Google already received. Reopening or changing these controls does not delete your theme preferences or local game records.
Manage data on your device
Use your browser's site-data controls to inspect, delete or restrict storage for calcr.app. Deletion can reset preferences and local game records. Restricting administrator session cookies can prevent signing in to the CMS, while ordinary public calculations do not need an administrator session.
See the privacy policy for information about page requests and administrator access, or contact for questions about your data.
