Site information
Privacy
This page explains what happens to information when you use Tollica’s Unit Converter and site preferences.
Calculations stay in your browser
Normal Unit Converter calculations run in your browser. The value and units you enter are not sent to a Tollica calculation service.
Information stored on this device
When browser storage is available, Tollica may save your theme and display preferences, current converter state, favorite units and conversions, recent conversions, selector preferences, and open or collapsed section choices. This information stays in this browser profile.
Hosting request information
Like other websites, Tollica’s hosting infrastructure may receive ordinary request information such as the requested URL, time, IP address, user agent, and operational or security logs. Retention and processing can depend on the hosting provider and deployment configuration.
External destinations
Standards references and optional social-sharing destinations open only after you choose them. Those external services apply their own privacy practices. Tollica does not load social-network SDKs or tracking pixels for the Share result feature.
Analytics, cookies, and monitoring
The current application does not include visitor analytics, advertising cookies or pixels, or a third-party error-monitoring service. If those practices change, this page will be updated before the service is introduced.
Clear locally stored information
Favorites and recent conversions can be cleared from the converter. To remove every Tollica preference and saved item, clear site data for tollica.com in your browser settings. This also resets the theme, display, selector, and section preferences stored in that browser.
