Privacy Policy

Default Public Calculator Processing

Data We Collect

Account Information (Optional)

If you choose to register an account:

• Email address: For authentication and account recovery
• Password: Stored as a salted PBKDF2-SHA256 hash
• Account preferences: Tool settings and favorites

Calculation History (Optional)

If you are logged in and choose to save your calculation history:

• Tool type and input parameters
• Full input snapshots for restoring saved runs
• Result summaries and metadata for reviewing prior calculations
• Timestamps

Note: Saved sequences in your library are stored in the application database so they can be restored later. History, Library, membership, and API workflows each use explicit save or request paths, while default public calculator screens run in the browser.

Usage Analytics (Google Analytics)

We use Google Analytics to understand how visitors use our site:

• Page views and navigation patterns

• Approximate geographic location (city/country level)
• Referral sources

Analytics records aggregate site interactions, not sequence content or result rows.
