Context Search Assistant (CSA)
Last updated: November 5, 2026

In brief: CSA sends the question you submit to its backend hosted on Cloudflare, which forwards it to Google's Gemini API to generate an answer. Notes you save in CSA are stored locally in your browser using Chrome's extension storage. CSA does not intentionally maintain a server-side history of your questions or notes.

1. What CSA does

Context Search Assistant is a browser extension that opens a floating assistant panel on a webpage. You can submit a question to receive an AI-generated answer and save notes for later viewing in the extension.

2. Information processed when you ask a question

When you submit a question, the text of that question is sent from the extension to the CSA backend hosted by Cloudflare. The backend sends the question to Google's Gemini API and returns the generated answer to the extension.

Cloudflare processes the request to operate and secure the backend. Request and diagnostic metadata, such as IP address, browser/request information, timestamps and response status, may be processed or appear in platform logs. The CSA backend is designed not to store a separate history of the question text.

Google processes the question to provide the Gemini response. Its handling of API data is governed by Google's applicable terms and privacy documentation: Gemini API terms and Google Privacy Policy.

Please avoid submitting passwords, payment details, sensitive personal information, or confidential material unless you are comfortable sending it to these service providers.

3. Notes and local storage

When you choose to save a note, CSA stores it locally using the browser extension storage API (chrome.storage.local). Notes are not uploaded to the CSA backend by this feature. They remain in that browser profile unless you clear the extension's stored data or remove the extension. Local notes may not automatically sync between different browsers or devices.

4. Information we do not intentionally collect

CSA does not require an account and does not intentionally collect your name or email address, track your browsing history, or maintain an analytics-based profile of your activity. CSA does not sell personal information.

5. Permissions

activeTab: allows CSA to interact with the current tab when you activate the extension.
scripting: allows CSA to inject its panel into the active webpage when you activate it.
storage: stores your saved notes locally in the browser.
Host access to the CSA backend: allows the extension to send questions to the CSA Cloudflare Worker.

6. Data security and retention

The Gemini API key is kept as a secret in the Cloudflare Worker environment and is not included in the browser extension. Data sent to Cloudflare and Google is subject to their respective security, retention and processing practices. No method of transmission or storage is completely risk-free.

7. Children's privacy

CSA is not designed specifically for children and does not knowingly collect personal information from children.

8. Changes to this policy

This policy may be updated as CSA's features or service providers change. The latest version and its update date will be published at this page.
