Privacy

Calculator inputs stay in your browser. This Worker does not provide an input-submission API. Advertising partners may process standard web request and consent signals according to their own policies.

What is stored

Temporary interface state may be stored locally only when a feature explicitly says so. Clearing site data removes it. Server logs may contain routine request metadata needed for security and reliability.

Advertising

This site uses Google AdSense. Consent controls and ad delivery can involve Google domains; ad blockers may prevent ad elements from loading.

Contact and corrections

If a method, example or compatibility note is wrong, verify the issue with a reproducible case before relying on the output elsewhere.
