Wireframer Privacy Policy

Wireframer is a Chrome extension that opens a wireframing panel beside the current page so users can create layout drafts, preview them, and export them as PNG images.

Last updated: March 14, 2026

1. Single Purpose

Wireframer has a single purpose: helping users create wireframes while viewing the current page in the same tab.

2. Information We Store

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

• It stores split-view preferences, such as panel width, in chrome.storage.local.
• 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.

• 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. Why Permissions Are Needed

• activeTab: used only after the user clicks the extension button, so the UI can open on the current tab
• scripting: used to inject the bundled CSS and JavaScript required to show and control the split view
• storage: used to save local UI preferences such as split-view width

6. Data Sharing and Sale

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

7. Data Retention

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