Do I need to sign in?
No. Calculators work the same with or without an optional Google sign-in, which stores only a few details.

No, sign-in is optional
You do not need to sign in to use any calculator. Calcylator offers an optional Sign in with Google, and calculators work the same with or without it.
Signing in is simply a choice you can make. The sections below explain exactly what is kept if you do.
What we store if you do sign in
We store what Google shares with us:
- Your Google account ID.
- Your email address and whether it is verified.
- Your name and the address of your profile picture.
- Your language setting.
- Your first and last sign-in time.
What we do not store
- We never see your Google password.
- We do not store Google’s access or refresh tokens.
- Favourites and history are not stored with your account.
- The numbers you enter in calculators are not stored.
We do not sell these details or use them for advertising. Sign-in is protected by a reCAPTCHA check.
Should you sign in?
If you only want to calculate, there is no need. Favourites and recently used calculators are kept in your browser whether or not you sign in, and they are not synced between devices.
Calculators, results, formulas and worked examples are the same either way.
