Big Calculator

Privacy Policy

Last updated 4 August 2026

Big Calculator does not ask who you are, and it has no account to sign in to. What you type into it stays on your device.

This policy covers two apps: Big Calculator, which is free and supported by advertising, and Big Calculator Plus, the paid version, which shows no advertising. Where the two differ, it says so.

What the app collects

Nothing. Neither version asks for your name, your email address or any other personal detail, and neither creates an account.

Your calculations, and your choice of theme, sound and memory keys, are stored on the device itself and are not sent anywhere. Deleting the app removes them.

Advertising, in the free version only

The free version shows a banner advertisement supplied by Google AdMob. To do that, Google receives information from your device — this typically includes your device's advertising identifier, general location derived from your IP address, device model and operating system version. That data is handled by Google, not by us, under Google's privacy policy.

We do not see who you are, we receive no personal data from Google, and no advertising code runs in the paid version at all.

Your choices

• Tracking. On first launch, iOS asks whether the app may track you across other companies' apps and websites. Declining is fully supported — the app works exactly the same, and you will still see advertising, just advertising that is not personalised. You can change this later in iOS Settings → Privacy & Security → Tracking.
• Consent, in the EEA and the UK. Where the law requires it, the app presents Google's consent form before any personalised advertising is served, and your choice is passed to Google.
• No advertising at all. Big Calculator Plus is the paid version and contains no advertising code.

What the app does not do

• No analytics. The app does not measure how you use it.
• No accounts, no sign-in, no cloud sync.
• No access to contacts, photos, microphone, camera or precise location.
• No network requests of its own. Apart from the advertising described above, the app makes no connections to any server, including ours.
• Nothing is ever sold or shared for anyone else's marketing.

Children

The app is not directed at children and collects nothing that could identify one. If you believe a child's personal information has somehow reached us, write to the address below and it will be deleted.

Your rights

Because we hold no personal data about you, there is nothing for us to show you, correct or erase. For the advertising data Google holds, see Google's privacy policy and the controls in your Google account.

Changes

If this policy changes, the date at the top of the page changes with it.
