Data Collection
BizSecurityTools is designed with privacy as a core principle. Most of our calculators run entirely in your browser — no data leaves your device. When we do collect information, it is limited to:
- Anonymized analytics — We use privacy-friendly analytics (such as Plausible or Fathom) that do not track individuals, set cookies, or store IP addresses.
- Email newsletter signups — If you subscribe for updates, we collect only your email address and use it solely for sending tool announcements.
- Contact form submissions — Messages sent through our contact form are stored for response purposes and not shared with third parties.
Client-Side Calculations
The following tools perform all calculations client-side in your browser. No input data, results, or personal information is transmitted to our servers:
- Password Strength Analyzer
- Subnet / CIDR Calculator
- All other calculators except where noted
