Privacy Policy

This site (hereinafter “the Tool”) is a purely client-side image stitching/merging tool. We take your privacy and data security seriously. This policy explains what information we do or do not collect, how it is used, and your rights.

1. Core Principles

  • No upload: The image files you select and process are not uploaded to our servers.
  • No persistence: Images are handled only in browser memory or via temporary object URLs and disappear when the page is closed.
  • Minimization: Anonymous analytics scripts are used only to the minimal extent necessary to improve the product (see Section 5).
  • Verifiable: You can verify that no images are sent out by checking the Network panel in your browser’s developer tools.

2. What We Do Not Collect

  • We do not collect or store any uploaded image content.
  • We do not collect or store any merged image content.
  • We do not use any form of persistent storage (such as Cookies, localStorage, or sessionStorage).
  • We do not collect your personally identifiable information (name, email, phone, etc.) unless you proactively contact us via email.
  • We do not perform fingerprinting or cross-site tracking.

3. Local Processing

Reading images, calculating sizes, laying out, and final composition are all executed in your browser. The merged result is provided directly for download in Base64/Blob format without passing through any remote server.

4. Temporary Objects and Release

  • After a file is loaded, an object URL (window.URL.createObjectURL) is created.
  • When you delete images or refresh/close the page, these references are released.
  • You can also actively clear selected images to free memory immediately.

5. Analytics and Third-Party Scripts

To improve user experience, we integrate Microsoft Clarity and Google Analytics, which load asynchronously.

  • We do not send any image data to Clarity or Google Analytics.
  • Clarity may collect anonymous usage information (such as time on page and click areas) and is governed by its own privacy policy.
  • Google Analytics may collect anonymous usage information (such as visit duration and browser type) and is governed by its own privacy policy.
  • If you prefer not to be included in anonymous analytics, you can use browser tracking protection, content blockers (e.g., uBlock Origin), or visit in private/incognito mode.

6. Cookies and Local Storage

The Tool does not use Cookies or local storage (localStorage/sessionStorage) to save any user data or preferences. All operations are performed within the current session, and data is cleared when the page is closed.
