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.
Analytics
CalcInfinity uses two third-party services to understand how the site is used and to catch performance problems — neither of them can see what you type into a calculator:
- Google Analytics 4 — records page views, general usage patterns, and approximate device/location information. It does not read the contents of any form field. See Google's Privacy Policy.
- Vercel Speed Insights — measures page-load performance (Core Web Vitals) anonymously. It sets no cookies and collects no personal data. See Vercel's Privacy Policy.
If we add any new tracking beyond what's described on this page, this page will be updated first, and what it collects and why will be disclosed here.
Advertising
CalcInfinity has applied to display ads through Google AdSense. The verification code Google requires is present on the site now, but ads will only actually appear once Google reviews and approves the site — until then, this section describes what will be true once ads go live.
Once ads are enabled, Google and its advertising partners may use cookies and similar technology to serve ads based on your visits to CalcInfinity and other websites, including for personalized advertising. We don't control what those partners collect or how they use it beyond what Google's own policies allow. You can review or opt out of personalized advertising at Google Ads Settings or aboutads.info/choices. See how Google uses information from sites that use its services for more detail.
Cookies and local storage
Google Analytics sets a small number of first-party cookies (the _gafamily) to distinguish visitors and sessions. Vercel Speed Insights sets no cookies at all. Once Google AdSense is approved and ads go live, Google and its advertising partners will also set cookies for ad delivery and personalization (see "Advertising" above) — we don't set those cookies ourselves and don't control their exact names or lifetimes. Your light/dark theme preference, favorited calculators, and recently used calculators are stored locally in your browser (via local storage, not cookies) — not on our servers, never transmitted anywhere — and simply persist between visits on the same device. Clearing your browser data removes all of the above.
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.
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.
