Information we collect
When you create an account, we collect your name and email address and store a one-way password hash. We also record account creation, update, and last-login timestamps. We use this information to authenticate your account and let signed-in users save calculator inputs in the browser. Creating an account is not consent to marketing email.
Calculator inputs
The numeric, date, health, financial, and other values you enter into calculators are processed in your browser using JavaScript. Without an account, those values are not saved and are lost when you leave or refresh the page. Signed-in users can have calculator inputs stored locally in the browser for convenience on return visits.
Retention and deletion
Account records remain while the account is active. You may request access, correction, or deletion by emailing hello@calculatorsdepot.com from the account address. Residual backup copies may remain for up to 30 days. Historical calculator-access lead records collected by an earlier version of the site are deleted within 24 months.
How we protect information
Account records are stored in a restricted database and submitted over HTTPS. Passwords are processed with PHP’s recommended one-way password-hashing algorithm and are never stored as plaintext. No internet service can guarantee absolute security, but we use access controls, prepared database queries, CSRF protection, and session ID rotation to reduce risk.
Standard server logs
Like most websites, hosting providers may keep temporary technical logs containing an IP address, browser type, requested URL, and timestamp for security and reliability.
Cookies and analytics
We use a temporary, HTTP-only session cookie to keep you logged in, protect forms against forged submissions, and apply basic abuse limits. It expires when the browsing session ends. We do not set advertising cookies or use behavioral analytics.
External services
Our interface loads Tailwind CSS from its public content delivery network. That provider may receive standard request information such as your IP address.
