Privacy Policy

Your privacy matters. This policy explains what data Allcalcy does and does not collect. In short: the calculators run in your browser, and the numbers you type are not sent to us.

Last updated: 23 July 2026

Calculations stay on your device

Every calculator computes results in your browser. The values you enter are not transmitted to a server, and they are never included in analytics. Privacy-sensitive tools, such as the cycle, net worth, password, and text tools, go further: they load no analytics and no advertising at all, and their pages are served with a policy that blocks outbound connections entirely.

Local storage

Some tools may save your last inputs or preferences in your browser's local storage so they are there when you return. This stays on your device and you can clear it at any time from your browser settings.

Analytics

We use Google Analytics 4, provided by Google, to understand how many people visit the site, which calculators are useful, and how many visitors come back. We do not receive the figures you enter into any calculator, and we do not try to identify you personally.

Google acts as a third-party processor and may set cookies in your browser to recognise a repeat visit. You can read how Google handles data from sites that use its services in Google's own explanation.

How this behaves depends on where you are, because the rules differ:

  • In the EEA, the UK, and Switzerland: analytics storage is switched off by default. No analytics cookies are set and no identifiers are stored. Google receives only aggregated, cookieless signals, so we can still count page views but cannot recognise you across visits.
  • Everywhere else, including India: analytics storage is enabled, so a cookie is used to tell a first visit apart from a return visit.

Advertising and ad-personalisation storage are switched off in every country, without exception.

Advertising

We do not currently display ads. If we add them, they will never appear on the privacy-sensitive tools listed above, and in regions where the law requires consent they will load only after you have given it. We will update this policy before any ads go live.

Cookies

We keep cookie use to a minimum. The site itself sets no cookies for logins or profiles, because there are no accounts. Your theme and tool preferences are kept in local storage rather than cookies. The only cookies that may be set are Google Analytics cookies, and only in the regions described above.

Your choices

You can opt out of analytics in several ways, and none of them stop the calculators working:

  • Install Google's official opt-out browser add-on, which disables Google Analytics on every site you visit.
  • Block or clear cookies for this site in your browser settings.
  • Use a browser or extension that sends a Global Privacy Control or Do Not Track signal, or that blocks analytics scripts.
  • Clear local storage at any time to remove saved preferences.

Because we hold no accounts and store no personal profile, there is nothing on our side to export or delete. If you want data that Google holds about your use of this site removed, that request goes to Google through the controls linked above.

Children

This site is intended for a general audience and is not directed at children. We do not knowingly collect personal information from children.

Changes to this policy

If we change what we collect or who processes it, we will update this page and move the date at the top. Material changes will be reflected here before they take effect.
