Privacy Policy

Last updated: July 2026

The short version

Every number you enter into a CalcInfinity calculator stays in your browser. Nothing you type — income, weight, dates, loan amounts, or anything else — is sent to a server, stored in a database, or seen by us. There are no user accounts, and calculators require no sign-up.

What we don't collect

We don't collect names, email addresses, phone numbers, or any other personal information through the calculators themselves. We don't require registration, and we don't build user profiles.

Cookies and local storage

CalcInfinity does not currently set any cookies. Your light/dark theme preference, favorited calculators, and recently used calculators are all stored locally in your browser (via local storage), not on our servers, and are never transmitted anywhere — they simply persist between visits on the same device. Clearing your browser data removes them.

Suggestions and feedback

The "Suggest a Calculator" form and the per-calculator "Was this helpful?" prompt don't submit anything to a server either — clicking send opens your own email client with a pre-filled message. Whether that email actually gets sent, and what it contains (your suggestion, an optional note, and an optional email address if you choose to include one), is entirely up to you at that point — it goes directly from your email provider to ours, not through CalcInfinity.

Analytics and advertising

CalcInfinity does not currently run any analytics or advertising scripts. If that changes in the future — for example, adding privacy-conscious usage analytics or ads to support the site — this page will be updated first, and any new tracking will be disclosed here along with what it collects and why.

Third-party links

Calculator pages sometimes reference external organizations (for example, tax authorities or health bodies) by name, without linking to them. Where we do link elsewhere, we aren't responsible for those sites' own privacy practices — check their policies separately.

Changes to this policy

If our data practices change, we'll update this page and update the "Last updated" date above. Continued use of CalcInfinity after a change means you accept the updated policy.
