Welcome to our Online Image Blur Tool ("the Tool"). We understand the importance of your privacy and are committed to protecting your personal information. We strive to maintain your trust by adhering to the following principles to protect your information: consistency of rights and responsibilities, clarity of purpose, choice and consent, minimum necessity, security assurance, subject participation, and transparency.

1. How We Collect and Use Your Information

The core principle of this tool is "zero data upload."

• Image Data: All images you upload and process with this tool are handled entirely locally within your browser. The image files are not uploaded to our servers or any third-party servers. From the moment you select an image to the moment you download the processed result, the entire process occurs on your device.
• Personally Identifiable Information: We do not require you to register an account, nor do we collect any personally identifiable information such as your name, email address, or phone number.

2. Client-Side Processing Technology

This tool utilizes the powerful capabilities of modern browsers, using JavaScript technology to compute and render image data directly on the client-side (i.e., your browser). This means your original and processed image data always remain on your computer or mobile device. We cannot access, view, or store them.

3. Cookies and Local Storage

This tool does not use any cookies for user tracking or advertising purposes. We may use the browser's LocalStorage to save non-sensitive interface settings (e.g., the last blur intensity you used), but this is solely to enhance your user experience, and the data is also stored only on your local device.

4. Third-Party Services

To provide functionality and improve the interface, this website loads some resources from trusted third-party CDNs (Content Delivery Networks). These include:

• Tailwind CSS & Font Awesome: Used for the website's styling and icons.
• StackBlur.js: Used to implement efficient blur algorithms.

These third-party services are only used to load static front-end resources and cannot access your uploaded image data. For information on their own privacy policies, please refer to their official websites.

5. Data Security

Because we do not collect or store your core data (images), the risk of your image data being leaked from our servers is fundamentally eliminated. You are the sole controller of your own data.

6. Changes to This Privacy Policy

We may revise this privacy policy from time to time. When the terms of the policy are changed, we will post the updated version on this page and update the "Last updated" date at the top. We recommend that you periodically review this page for the latest information.

7. How to Contact Us

If you have any questions, comments, or suggestions about this privacy policy, you can contact us through the contact information provided in the footer of our website. We will review the issues involved as soon as possible and provide a response.
