Privacy
This summary explains the main categories of data used to operate the app, measure product usage, and serve advertising on public pages.
Essential product data
We use essential cookies and related storage to keep users signed in, preserve calculator state, maintain security protections, and remember theme preferences.
If you create an account, we store the account details and saved scenarios needed to provide the service.
If you submit feedback, we may store the message, optional reply email, page context, and any calculator inputs you explicitly choose to share so we can review and improve the product.
Telemetry
We use Application Insights telemetry to understand feature usage, diagnose issues, and improve the product.
This includes operational telemetry for the service and browser telemetry such as route views and client-side failures.
Advertising
This site may display ads delivered by Google AdSense on public content and calculator pages.
Where required, consent for advertising is handled through Google Privacy & messaging rather than the app's own cookie banner.
Notice
The in-app banner is an informational telemetry notice rather than an analytics opt-in control.
For advertising in supported regions, Google Privacy & messaging provides the relevant consent and privacy controls.
