UUID Generator
ZERO SERVER LOGS • 100% CLIENT-SIDE

Privacy Policy

Last updated: September 3, 2026. This policy explains our architectural commitment to privacy-by-design: we generate cryptographically strong UUIDs directly in your browser with zero telemetry.

Our Architecture at a Glance

01. Web Crypto API
100% In-Browser Execution

Every UUID is computed by your local CPU using hardware-backed CSPRNG.

02. Zero Network Logs
No Transmitted Keys

UUIDs never touch our backend, databases, or edge reverse proxies.

03. No User Tracking
Zero Tracking Cookies

We do not set profiling cookies, marketing pixels, or user fingerprints.

1. Information We Do Not Collect

Unlike traditional web generators that send HTTP requests to generate identifiers on remote servers, Bulk UUID Generator operates exclusively within your client environment.

  • No Generated Identifiers: We do not receive, store, or log any UUID, GUID, or cryptographic material generated by you.
  • No Personal Identifiable Information (PII): We do not require registration, login, email addresses, or payment information.
  • No IP or Device Logging of Tool Usage: Your batch configurations, version preferences, and inspection strings remain in memory on your device.

2. How Client-Side Generation Works

When you click "Generate" or use the bulk generator up to 5,000 items:

  1. Your browser invokes the standardized crypto.getRandomValues() interface provided by your operating system's cryptographic random number generator (CSPRNG).
  2. For large batch generation, processing occurs in a dedicated local Web Worker or batch loop that formats the output directly into browser memory.
  3. Exports (JSON, CSV, SQL, Plain Text) are compiled into local Blobs via URL.createObjectURL and downloaded directly to your disk without server interaction.

3. Local Storage and Client-Side State

We use browser localStorage solely to remember your user interface preferences:

  • theme: Stores your light or dark mode selection ("light" or "dark") to prevent visual flashing on subsequent visits.

No generated UUIDs or operational inputs are ever written to persistent storage unless you explicitly initiate a download. You can clear this preference at any time through your browser settings.

4. Infrastructure and Third-Party Hosting

Our application files (HTML, CSS, JavaScript, icons) are served statically via reputable global Content Delivery Networks (CDNs). Like all web servers, the hosting CDN may automatically record standard connection logs (such as request timestamps and HTTP status codes) to ensure DDoS mitigation, uptime monitoring, and protocol routing. These transient logs contain no user data from our application's cryptographic operations.

5. GDPR & CCPA/CPRA Compliance

Because we do not collect, process, or sell any personal data:

  • There is no personal information database subject to data breaches.
  • There are no marketing databases or tracking profiles to opt out of or request deletion for.
  • Your usage remains entirely anonymous, private, and self-contained.
