Introduction
CalculatorDrive ("we," "us," or "our") operates calculatordrive.com and related pages that provide free online calculators, guides, and optional account features.
We respect your privacy. We collect only what we need to run the site, keep it secure, understand how it is used, and respond when you contact us. We do not sell your personal information.
By using CalculatorDrive, you agree to this Privacy Policy. If you do not agree, please do not use the site. For how we use cookies specifically, also read our Cookie Policy.
Who This Policy Applies To
This policy applies to visitors who browse our calculators without an account, users who create an optional CalculatorDrive account, and anyone who contacts us by email or through site features.
You can use most calculators without registering. An account is only needed for optional features such as saving favorite calculators.
Information We Collect
Information you provide directly
- Account details if you register — such as your email address, display name, and password (stored in hashed form)
- Profile or preference settings you choose to save
- Messages you send us — support requests, bug reports, or feedback
- Newsletter or blog subscription details, if you opt in
Information collected automatically
- Device and browser type, operating system, and screen size
- Pages and calculators you visit, referral source, and general site usage patterns
- Approximate location derived from IP address (such as country or region — not precise GPS)
- IP address, timestamps, and server logs used for security and troubleshooting
- Cookie and similar technology data as described in our Cookie Policy
Information from third parties
If you sign in through a third-party provider (where supported), we may receive basic profile information permitted by that provider and your account settings. We use it only to operate your CalculatorDrive account.
Calculator Inputs & Results
Most standard calculators process your inputs in your browser or in a single request to our servers to return a result. We do not require you to enter bank account numbers, government ID numbers, full medical records, or similarly sensitive identifiers to use a typical calculator.
We do not use calculator inputs to build a personal health or financial profile about you. We do not sell calculator usage data as a standalone product.
