Privacy Policy

Last updated: November 14, 2026

Backtrack is a Chrome extension for claude.ai. It is built to work entirely inside your browser. This page explains, in plain words, what it reads, what it stores, and the few times it talks to the internet.

The short version

• Your chats never leave your browser. We never see them.
• There is no Backtrack account and no Backtrack server that stores your data.
• Backtrack has no analytics, no tracking and no ads.
• The only outside service it talks to is Polar, our payment provider, and only to check a Pro license key.
• We do not sell, share, or rent any data.

What Backtrack reads

On claude.ai, Backtrack reads your chat list and the chats you work with (titles, messages, every version of a chat, project names, and files Claude made in a chat) only to do what you ask: sort chats into folders, save a chat as a file, back up your chats, and show the versions of a chat. It reads them from the claude.ai page itself, the same way that page does, using your existing claude.ai sign-in. These requests go to claude.ai only.

What Backtrack stores, and where

Everything Backtrack keeps is stored on your computer, in your browser's extension storage:

• Your folders, which chats are in which folder, and the titles of those chats.
• Your settings, including your PDF style choices (for example, a name you type for a PDF cover page).
• Your Pro license key and its activation details, if you bought Pro.
• Small bookkeeping: when your last backup ran and how many chats it saved, how many free tries you have used, and short error notes that help Backtrack recover when claude.ai changes.

Backtrack does not keep copies of your chat messages in storage. Removing the extension deletes everything it stored.

Files you save

When you save a chat or run a backup, Backtrack creates the file inside your browser and hands it to Chrome's normal download feature. Files go to your Downloads folder (backups go to a Backtrack folder inside it), or wherever you choose. They are never uploaded anywhere.

Network requests

Backtrack makes only these requests:

• claude.ai: to load your chats, as described above. Never to us.
• Polar (polar.sh): only if you use Pro. When you activate, check, or deactivate a license key, Backtrack sends Polar your license key, our store id, and a generic label ("Backtrack (Chrome)"), plus an activation id after the first activation. It checks the key about once a week. Polar never receives your chats or chat titles. Polar handles payment on its own checkout page; Backtrack never sees your card details. Polar's privacy policy covers your purchase.

Backtrack also opens a few pages in a new tab: this website's welcome page after you install it, Polar's checkout or customer portal when you click Get Pro or Restore purchase, and a short "why did you leave?" page after you uninstall. That page sends nothing unless you choose to email us from it.

After you buy Pro

Polar sends you back to backtrackchats.com/thanks with a short-lived (one hour) Polar session code in the address. The page removes it from the address bar right away and uses it to ask Polar for your license key so it can show it to you. If Backtrack is installed, a small part of the extension that runs only on that page receives the same code, asks Polar for your key, and activates Pro for you. The code and key go only between your browser and Polar.

This website

backtrackchats.com is a static website with no cookies, no analytics and no trackers. Our host, Cloudflare, processes standard request data (such as your IP address) to deliver the pages. The free Export Viewer opens your Claude export file inside your browser; the file is never uploaded.

Chrome Web Store Limited Use

The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements.

In practice: Backtrack uses the data it can access only to provide the features described above, which you can see and control. It does not sell or transfer that data to anyone (the only data that leaves your browser is your license key, sent to Polar to check it), does not use it for advertising or to decide creditworthiness or lending, and no person reads it.

Children

Backtrack is not directed at children under 13 and does not knowingly collect information from them.

Changes

If this policy changes, we will update this page and the date at the top. Meaningful changes will also be noted in the extension's release notes.
