2. Information We Collect

Information you provide: When you create an account using Google sign-in or magic link, we collect your email address and display name. When you use the calculator, you enter income figures and expense amounts — if you have an account, these may be saved to our servers.

Information collected automatically: We use cookies and similar technologies to collect analytics data including pages visited, browser type, device type, and general location. We also store your currency preference in your browser's local storage.

3. How We Use Your Information

We use your information to: provide and maintain the calculator service, save your calculator configurations if you have an account, remember your currency preference, analyse usage patterns to improve the service, and display relevant advertisements.

5. Google User Data

When you sign in with Google, we access your basic profile information (name and email address) solely to create and manage your account. We do not access any other Google account data.

We retain your account data for as long as your account is active. You may request deletion of your account and all associated data at any time by contacting us at the email below. Upon account deletion, all your saved configurations and personal data are permanently removed from our servers. Browser local storage data can be cleared through your browser settings at any time.
