What we store if you sign in
If you sign in with Google, see exactly which details we store, what we never see, and what stays out of your account.
Updated · Sharing, accuracy and privacy
Signing in is optional
Calculators work the same with or without Google sign-in. If you do sign in, we store only what Google shares with us. The sign-in is protected by a reCAPTCHA check.
If you would rather not share these details, you can carry on without signing in. No sign-up is needed to use any calculator, and the answers are the same.
What we store
| Detail | What it is |
|---|---|
| Google account ID | The identifier Google uses for your account |
| Email address | The email on your Google account, and whether it is verified |
| Name | The name on your Google account |
| Profile picture address | The web address of your Google profile picture |
| Language setting | The language set on your Google account |
| Sign-in times | When you first and last signed in |
These are the details Google shares with us when you choose to sign in. Your sign-in happens on Google, so your password goes to Google and not to us.
What we do not store or see
- Your Google password. We never see it.
- Google's access or refresh tokens.
- The numbers you enter in calculators.
- Your favourites and history. They are not stored with your account.
Because favourites and history stay in your browser, signing in does not carry them to another device.
How these details are used
We do not sell these details or use them for advertising.
