Design Jam — Privacy Policy

Last updated: February 21, 2026

Design Jam is a Chrome extension that lets designers annotate web pages and export structured prompts for AI coding agents. This policy explains how the extension handles data.

The short version

Design Jam does not collect, transmit, or store any personal data. Everything stays on your machine.

What data the extension accesses

When you activate Design Jam on a web page, the extension reads:

• DOM structure — HTML elements, CSS selectors, tag names, class names, and component identifiers (React/Vue) of elements you interact with.
• CSS properties — Computed styles (layout, typography, colors, spacing) of inspected elements.
• Page content for ASCII flattening — Bounding rectangles and text content of DOM subtrees you choose to capture onto the ASCII canvas.

This data is used solely to power the annotation overlay, CSS inspection panel, and DOM-to-ASCII canvas features.

Where data is stored

All data — annotation sessions, comments, pin positions, canvas states — is stored locally in your browser using IndexedDB within the extension's own origin. Nothing is sent to any external server.

What the extension does NOT do

• Does not collect personal information (name, email, age, etc.)
• Does not track browsing history or navigation patterns
• Does not monitor network activity, clicks, scrolling, or keystrokes outside the extension's own UI
• Does not transmit any data to external servers, APIs, or third parties
• Does not use analytics, telemetry, or tracking scripts
• Does not use cookies
• Does not use remote code

Speech-to-text

Design Jam offers an optional voice dictation feature using the browser's built-in Web Speech API. When activated by clicking the microphone button, audio is processed by your browser's speech recognition service (typically Google's servers on Chrome). Design Jam itself does not record, store, or transmit any audio data. You can choose not to use this feature.

Permissions

The extension requests the following Chrome permissions:

Permission	Purpose
activeTab	Detect and inspect page elements under the cursor when the overlay is active
storage	Persist annotation sessions and canvas data locally in IndexedDB
scripting	Inject the content script into tabs that were already open before installation
Host access	Run the annotation overlay on any web page you choose to activate it on

Third-party services

Design Jam does not integrate with any third-party services. Exported prompts are copied to your clipboard — where you paste them is your choice.

Changes to this policy

If this policy changes, the updated version will be posted at this URL with a revised date. Since Design Jam's architecture is local-first by design, meaningful changes are unlikely.
