Privacy Policy

Last updated: December 2024

Information Collection

SREcalc is designed with privacy as a core principle. We do not collect, store, or transmit any personal information or usage data to external servers. All calculations and data processing occur entirely within your browser using client-side JavaScript.

The only data stored is in your browser's local storage (localStorage), which is used solely to remember your preferences and input values for your convenience. This data never leaves your device and can be cleared at any time through your browser settings.

Data Usage

Since we do not collect personal data, there is no data usage, sharing, or selling of information. Your calculations remain private and are not accessible to us or any third parties.

Local storage data is used exclusively to:

  • Remember your input values between sessions
  • Preserve your selected preferences
  • Enhance your user experience

Cookies

SREcalc does not use cookies. We rely solely on browser localStorage for storing your preferences, which is more transparent and gives you full control over your data.

Third-Party Services (Analytics)

We do not use any third-party analytics services, tracking pixels, or advertising networks. Your visit to SREcalc is completely private and untracked.

If you access SREcalc through a hosting platform (such as Vercel), their standard access logs may record basic connection information (IP address, timestamp) as part of normal web server operations. This is standard practice and not under our direct control.

Your Rights

Since we do not collect personal data, there is no personal data to access, modify, or delete. However, you have full control over the data stored in your browser:

  • Clear localStorage data through your browser's developer tools or settings
  • Disable JavaScript to prevent any data storage
  • Use private/incognito browsing mode

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last updated" date. We encourage you to review this policy periodically.
