Your numbers, answers, formulas and copied text stay in browser memory. They are not uploaded, saved to storage or placed in a link. Editing, clearing, navigating away or reloading removes the previous result.

Analytics

This version may send optional anonymous analytics only under calc.unboundcove.com; QA visits send none. This tool uses Umami only on its confirmed production or staging hostname for fixed page paths and action categories, including which of the four modes was used. No numbers, outputs, query strings, hashes or raw referrers are sent. Visits and actions are counts, not verified users or task satisfaction.

Analytics settings lets you opt out with a localStorage preference. QA uses a sessionStorage exclusion flag. Do Not Track, unavailable storage, localhost and unapproved hosts disable analytics. QA links keep qa=1 across site navigation. This does not hide hosting access logs.

Voluntary feedback

Only your chosen rating, fixed reason and optional message are sent. No calculation is attached. Ordinary feedback goes to the production service and database, retained for 90 days. QA feedback goes only to the independent test service and database, retained for 7 days. QA always uses the test service and database. Cloud submissions require Turnstile, loaded only when submitting. Cloudflare verification loads only when you choose to send feedback.

Support is optional and one-time. PayPal loads only after you open the support dialog and handles checkout under its own terms. Your numbers and results are never attached. The author button is shared with InvisiChar and may show “Support InvisiChar”. Calculations remain free.
