Privacy Policy
Last Updated: November 14, 2026
1. Browser-First Calculation Privacy
Public calculations on PureCalculator.net execute locally within your browser runtime. Inputs entered into mortgage, tax, loan, health, sleep, or math tools are not automatically transmitted to third-party data brokers or stored in marketing databases.
2. Optional Saved Workspace Data
If you voluntarily create a PureCalculator member account, we store only the account credentials (hashed using salted bcrypt), saved calculation snapshots, favorites, and progress logs you explicitly request to keep synchronized across sessions.
3. Operational Logs & Security
Our infrastructure records minimal anonymous aggregate telemetry (such as page view counts, device viewport category, and error diagnostics) solely to maintain uptime, enforce rate limiting against automated abuse, and improve broken routes.
4. Your Data Rights
You may request export or permanent deletion of any saved member workspace records at any time by writing to [email protected].
