Wireframer Privacy Policy

Wireframer is a Chrome / Edge-compatible browser extension that opens a wireframing panel beside the current page so users can create layout drafts, preview them, export them as PNG images, and copy PNG images to the clipboard.

1. Single Purpose

Wireframer has a single purpose: helping users create wireframes in the browser's native side panel while viewing reference pages.

2. Information We Store

Wireframer does not send personal information, browsing history, page content, or authentication credentials to the developer's servers.

• It may store limited UI preferences in browser local storage (for example, left-rail text visibility).
• This data stays in the user's browser and is not transmitted to the developer.
• It does not use analytics, advertising trackers, or remote code execution.

3. External Image URLs

If a user enters an image URL, Wireframer attempts to load that image directly from the specified server for preview or PNG export. When needed, Wireframer requests optional host permission for that origin.

• Image requests are made without cookies or authentication credentials.
• The image host may receive standard technical request information required to deliver the image.
• If cross-origin restrictions prevent access, the image cannot be used for preview or export.

4. Local Files

If a user selects an image through the Local File feature, that file is processed locally in the browser. It is not uploaded to the developer.

5. Preview, PNG Export, and Clipboard

Preview, PNG export, and Copy PNG are generated locally in the browser from the user's current Wireframer layout. Generated images are not sent to the developer's servers.

• Preview renders the current layout for user review.
• PNG saves the generated image as a local download.
• Copy PNG writes the generated image to the clipboard only when the user clicks the Copy PNG button.
• Wireframer writes image data to the clipboard for this feature, but it does not read clipboard contents.

6. Why Permissions Are Needed

• sidePanel: required to open and control the Wireframer UI in the browser's native side panel
• optional_host_permissions (http://*/*, https://*/*): requested only when a user-provided remote image requires host access for rendering

7. Data Sharing and Sale

Wireframer does not sell user data and does not share user data with third parties on behalf of the developer.

8. Chrome Web Store Limited Use

Wireframer's use of information complies with the Chrome Web Store User Data Policy, including the Limited Use requirements. Wireframer uses data only to provide or improve its single purpose described above.

9. Data Retention

Local preference data remains in the browser until the user clears browser data or uninstalls the extension.
