Privacy Policy

Last updated: November 2026

At CryptoTools Hub, we take your privacy seriously. This Privacy Policy explains how we handle information when you use our website and tools.

1. Information We Do Not Collect

The most important thing to know about CryptoTools Hub is that we do not collect, store, or transmit any data you enter into our tools. All of our tools run entirely within your web browser using client-side JavaScript. When you:

• Generate a password
• Check password strength
• Encode or decode Base64
• Encode or decode URLs
• Generate MD5 or SHA hashes
• Format JSON
• Generate QR codes

...the data you enter never leaves your device. There is no server-side processing of your input.

2. Information We May Collect

While we do not process the content you enter into our tools, our website may collect limited technical information necessary for the website to function:

• Browser type and version — to ensure compatibility
• Operating system — for technical support purposes
• Pages visited — to understand which tools are most popular
• Referral source — to understand how visitors find us

This information is collected through standard web server logs and does not include any personal identifiers or the content of your tool usage.

3. Cookies

CryptoTools Hub does not use cookies for tracking or advertising. We may use essential cookies or local storage only to remember your tool preferences (such as selected options) for convenience. We do not use third-party tracking cookies.

4. Third-Party Services

We may use third-party services for website analytics (such as Google Analytics) and to display advertisements. These services may collect anonymous usage data according to their own privacy policies. We encourage you to review the privacy policies of any third-party services.

Our QR code generator uses the qrcode.js library loaded from a CDN. No data is sent to the CDN — the library is simply downloaded and executed in your browser.

5. Data Security

Because all tool processing happens in your browser, your data is as secure as your own device. We recommend keeping your browser and operating system up to date and using reputable antivirus software.

6. Your Rights

Since we do not collect personal data, there is no personal information for us to provide, correct, or delete. If you have questions about your privacy, please contact us.

7. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by updating the "Last updated" date at the top of this page. Continued use of our website after changes constitutes acceptance of the updated policy.
