What We Collect and Why

Effective Date: May 14, 2026 · Version 1.0

Short version: Kennr reads the design of the page you point it at — colors, fonts, spacing — and sends that to an AI for analysis. It does not collect personal information, does not track you, and does not sell anything. You control where the data goes.

What the Extension Reads

When you click the Kennr button, the extension reads the following from your active browser tab:

The page's HTML source (outerHTML) — used to extract design tokens like colors, fonts, and layout
The URL of the active tab — attached as a source reference on the analysis result
A screenshot of the visible portion of the tab — used for visual design analysis

The extension does not read any other tabs, your browsing history, cookies, form data, or login credentials.

What Is Stored Locally

Two settings are saved to Chrome's sync storage and synced across your signed-in Chrome profile:

Your backend URL (the Kennr Worker endpoint you configure)
Your project name

No page content is stored locally or in your Chrome profile.

What Is Sent to the Backend

The HTML source, page URL, and screenshot are sent to the backend URL you configure. By default this is the Kennr Cloudflare Worker at kristh-worker.justinaiark101.workers.dev. You can point the extension at your own backend instead — the extension does not hard-code any destination.

The backend processes your request through an AI model to produce the design analysis. Project records — the extracted design data and analysis results — are stored in a Cloudflare D1 database tied to the worker. No personal information is included in these records: only design data extracted from the page you analyzed.

What We Do Not Do

We do not collect your name, email, or any account information
We do not track you across sites or sessions
We do not use analytics or advertising pixels of any kind
We do not sell, rent, or share your data with third parties
We do not read pages you did not explicitly submit for analysis

Third-Party Services

The default backend uses Cloudflare Workers and Cloudflare D1 for compute and storage. Cloudflare's infrastructure privacy terms apply to data processed there. AI inference is handled by a large language model — the page content you submit is passed to that model for analysis and is not used for model training.

Your Control

You decide what gets analyzed. Nothing is sent automatically — every extraction is triggered by you clicking the button on a specific tab. You can point the extension at your own backend at any time by changing the backend URL in the extension popup.

To remove all locally stored settings, clear the extension's storage via Chrome's extension management page or uninstall the extension.

Changes to This Policy

If this policy changes materially, the effective date above will be updated. Continued use of the extension after a change constitutes acceptance of the updated policy.
