How we handle data and device settings

Current service scope

We do not offer user registration, brokerage connections, or server-side account storage. Investment conditions entered into a calculator are processed in your browser and are not sent to or stored on our server.

On-device theme and language settings

Your light or dark theme selection may be stored in your browser's local storage. This value is used only to remember your display preference.

Your language selection may be stored in the tujamap-locale cookie for up to one year. This cookie is used only to remember your selected display language.

Service usage analytics

We use Vercel Web Analytics to understand service usage and improve the interface. Anonymized usage statistics, such as pages visited, referral sources, browser, operating system, and device type, may be processed. We do not use custom user events, and values entered into calculators are not sent as analytics events.
