Privacy Policy — AI Branch

Last updated: September 9, 2026

AI Branch is a browser extension that adds a branching/navigation layer on top of your conversations on ChatGPT, Claude, and Gemini. This policy explains what data the extension touches and what it does with it.

Summary

AI Branch does not collect, transmit, or sell any user data. It has no backend server, no analytics, no telemetry, and makes no network requests of its own. Everything it stores lives only in your own browser, on your own device, via the standard chrome.storage.local API, and is never sent anywhere by the extension.

What the extension does with page content

AI Branch reads the conversation already visible on chatgpt.com, chat.openai.com, claude.ai, and gemini.google.com — the question and answer text on those pages — in order to:

build the branching tree/navigation structure you interact with,
insert text you've composed into that page's own message box on your behalf, when you use a "branch" or "ask another AI" action.

This happens entirely inside your browser. AI Branch does not read pages outside these four sites, and never forwards anything it reads to any third party or server the extension's authors operate — there isn't one.

What's stored, and where

Your branch tree (questions, answers, and the navigation structure between them) is stored locally via chrome.storage.local.
Nothing is synced to any account, cloud service, or remote server.
Uninstalling the extension removes this data along with it (standard chrome.storage.local behavior).

Permissions, and why each is requested

Permission	Why
`storage`, `unlimitedStorage`	Store your branch tree locally in the browser — trees can grow large, so the unlimited variant avoids an arbitrary cap.
`tabs`	Open, focus, and coordinate between the browser tabs involved in branching (e.g. opening a new tab for "ask another AI").
`downloads`	Save a branch tree you export (Markdown, JSON, HTML, or PDF) to your own Downloads folder, only when you click Export.
Host permissions (chatgpt.com, chat.openai.com, claude.ai, gemini.google.com)	Read the conversation on the page and insert text into it — the extension's entire purpose. It does not run on any other site.

Third parties

None. AI Branch does not integrate any analytics SDK, ad network, or external API. The only network requests that happen while using it are the ones you'd already be making to ChatGPT/Claude/Gemini yourselves by using those sites normally.

Changes to this policy

If this policy changes, the "Last updated" date above will change with it. Material changes (e.g. adding a new permission or any form of data collection) will be reflected here before being submitted for store review.
