Information We Collect

The Regex Editor & Tester is designed with privacy in mind. We collect minimal information to provide and improve our service:

  • Usage Analytics: We may collect anonymous usage statistics to understand how the service is used and to improve functionality.
  • Technical Information: Basic technical information such as browser type, device type, and general location (country level) for service optimization.
  • No Personal Data: We do not collect names, email addresses, or other personal identifying information unless you voluntarily provide it through our contact form.

Your Regex Data

Important: We do not store, log, or transmit your regex patterns or test strings.

All regex processing happens entirely in your browser (client-side). This means:

  • Your regex patterns never leave your device
  • Your test strings are not sent to our servers
  • No regex data is stored in our databases
  • Your work remains completely private and secure

Cookies and Local Storage

We use minimal cookies and local storage for essential functionality:

  • Theme Preference: We store your dark/light mode preference locally in your browser
  • Essential Cookies: Necessary cookies for basic website functionality
  • No Tracking Cookies: We do not use cookies for tracking or advertising purposes

Third-Party Services

We may use third-party services for:

  • Analytics: Anonymous usage analytics to improve the service
  • CDN Services: Content delivery for faster loading times
  • Hosting: Reliable service hosting and delivery

These services may collect anonymous technical information as described in their respective privacy policies.

Data Security

We implement appropriate security measures to protect against unauthorized access, alteration, disclosure, or destruction of information. Since we don't store your regex data, the risk of data breaches affecting your patterns is eliminated. For more information about our security practices, please see our About page.

  • Use the service without providing personal information
  • Clear your browser's local storage at any time
