Introduction
UUIDGen ("we," "us," or "our") is committed to protecting your privacy. This Privacy Policy describes how we collect, use, and share information when you visit and use our website at uuidgen.pages.dev (the "Service"). By using the Service, you agree to the terms outlined in this policy.
UUIDGen is a free online tool that generates universally unique identifiers (UUIDs). The core functionality of the Service operates entirely within your web browser — no UUID data, generation parameters, or usage patterns are transmitted to our servers.
Information We Collect
Information We Do Not Collect
UUIDGen is designed with privacy as a fundamental principle. We do not collect:
- UUIDs that you generate — all generation occurs client-side in your browser
- Personal information such as names, email addresses, or phone numbers
- Account credentials — the Service does not require registration or login
- Generation settings or preferences you configure (case, format, version)
- Bulk generation data — the UUIDs you download or copy never reach our servers
Information Collected Automatically
When you visit UUIDGen, our hosting provider (Cloudflare) may automatically collect standard web server log data, including:
- IP address (anonymized after 24 hours)
- Browser type and version
- Operating system
- Referring URL
- Pages visited and time spent
- Date and time of access
This data is used solely for maintaining the security and performance of the Service. We do not use this data to identify individual users or build user profiles.
Cookies and Tracking Technologies
Essential Cookies
UUIDGen itself does not set any cookies. The core functionality of the Service works without cookies, and we do not use cookies for analytics, session tracking, or user identification.
Third-Party Cookies (Google AdSense)
To support the free operation of this Service, we display advertisements provided by Google AdSense. Google AdSense may use cookies and similar technologies to serve ads based on your prior visits to this or other websites. Specifically:
- Google uses the DoubleClick cookie to serve ads based on your browsing history
- You may opt out of personalized advertising by visiting Google Ads Settings

Third-Party Services
UUIDGen uses the following third-party services:
- Cloudflare Pages — Hosting and content delivery. Cloudflare may process access logs for security and performance purposes. See Cloudflare's Privacy Policy.
- Google AdSense — Advertising. Google may use cookies to serve personalized ads. See Google's Privacy Policy.
We do not sell, trade, or otherwise transfer your personal information to any other third parties.
Data Security
We take reasonable measures to protect the Service and its users:
- The Service is served exclusively over HTTPS, encrypting all data in transit
- No user data is stored on our servers, eliminating the risk of data breaches
- UUID generation uses the browser's cryptographic random number generator (
crypto.getRandomValues), ensuring generated identifiers are not predictable - The Service has no server-side code, backend database, or API endpoints, minimizing the attack surface
Children's Privacy
The Service is not directed to children under 13. We do not knowingly collect personal information from children. If you are a parent or guardian and believe your child has provided personal information through this Service, please contact us so we can take appropriate action.
Your Rights
Depending on your jurisdiction, you may have the following rights regarding your personal data:
- Right to access — You may request information about what data we hold about you. Since we do not collect personal data, there is typically nothing to disclose.
- Right to deletion — You may request deletion of any personal data we hold. Since we do not store personal data, this right is satisfied by default.
- Right to opt out of tracking — You may opt out of personalized advertising through the Google Ads Settings link above, or by using browser extensions that block third-party cookies.

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, or legal requirements. Any changes will be posted on this page with an updated "Last updated" date. We encourage you to review this policy periodically to stay informed about how we protect your privacy.
