Privacy Policy

Last updated: 2026-05-03

1. About This Privacy Policy

This Privacy Policy explains how Regex Test Case Builder ("the Site," "we," "us") collects, uses, and shares information when you visit regex-test-case-builder.hub2.day. The Site is a focused utility for generating edge-case strings and expected matches to help developers and QA engineers validate regular expressions. We are committed to transparency and minimizing data collection.

2. Information We Collect

2.1 Information You Provide Directly

Contact email. If you reach out to us at hello@regex-test-case-builder.hub2.day, we receive your email address and any information you include in your message. We use this only to respond to your inquiry and do not add you to marketing lists.

2.2 Information Collected Automatically

Browser-local tool inputs. The regular expression patterns, test strings, and flags you type into the builder are processed entirely inside your browser. They are not sent to our servers and we do not see, store, or log them.

Server and security logs. Our hosting infrastructure may automatically record technical details such as your IP address, browser type, referring page, and timestamps. These logs are used solely for security, diagnostics, and aggregated traffic analysis, and are retained for up to 30 days.

Cookies and local storage. The Site itself uses a minimal amount of local storage to remember your tool preferences (such as dark mode or last-used flags) so the builder works smoothly across visits. This data stays on your device and is not transmitted to us.

3. Advertising and Third-Party Services

We use Google AdSense to display advertisements on the Site. Google AdSense uses cookies and similar technologies to serve ads based on your prior visits to this Site and other websites. Google’s use of advertising cookies enables it and its partners to serve ads based on your browsing activity.

We do not control the cookies or tracking technologies used by Google or other third-party advertisers. Their practices are governed by their own privacy policies.

4. GDPR, EEA, and UK Privacy Rights

If you are located in the European Economic Area or the United Kingdom, you have certain rights under the General Data Protection Regulation (GDPR) and UK GDPR, including:

  • Access and portability: You can request a copy of the personal data we hold about you.
  • Rectification and erasure: You can ask us to correct or delete your personal data.
  • Restriction and objection: You can ask us to limit processing or object to processing based on legitimate interests.
  • Consent withdrawal: Where we rely on consent (such as for non-essential cookies), you can withdraw it at any time.

We process personal data on the legal bases of consent (for advertising cookies), legitimate interest (for security logs and responding to contact requests), and contractual necessity where applicable. To exercise your rights, email hello@regex-test-case-builder.hub2.day. We will respond within one month.

5. CCPA / CPRA Privacy Rights (California)

If you are a California resident, you have the right to:

  • Know what personal information we collect, use, disclose, and sell.
  • Request deletion of your personal information.
  • Opt out of the sale or sharing of personal information.
  • Not be discriminated against for exercising your privacy rights.

We do not sell personal information in the traditional sense, but our use of Google AdSense may involve the sharing of cookie and device data for targeted advertising, which may be considered a “sale” or “sharing” under California law. You can exercise your opt-out rights by using the cookie consent controls presented on the Site or by emailing hello@regex-test-case-builder.hub2.day.

6. Service Providers

We may engage trusted third-party companies to assist with hosting, analytics, and advertising. These providers only access data as needed to perform their functions and are contractually obligated to protect it.

7. Data Retention

We keep contact emails and responses for up to 12 months for reference. Server logs are retained for up to 30 days. Local storage data remains on your device until you clear it through your browser settings.

8. Children’s Privacy

The Site is not directed to individuals under the age of 16, and we do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us so we can delete it.

9. Security

We implement reasonable technical and organizational measures to protect the limited data we process. However, no internet transmission is completely secure, and we cannot guarantee absolute security.

10. Third-Party Links

The Site may contain links to external resources or documentation. We are not responsible for the privacy practices or content of those third-party sites.

11. International Data Transfers

Your information may be transferred to and processed in countries outside your own, including the United States. We take steps to ensure that such transfers comply with applicable data protection laws.

12. Changes to This Policy

We may update this Privacy Policy from time to time. The “Last updated” date at the top will reflect the most recent changes. Continued use of the Site after changes constitutes acceptance of the revised policy.
