TagChannel Privacy Policy

Effective date: 2026-10-09 · Applies to the TagChannel Chrome extension (v1.0.0 and later) and its licensing API.

Summary

Your tags, tag assignments and conversation titles/links stay on your device (the extension's IndexedDB and chrome.storage).
Conversation content is read from the ChatGPT page only when you click “Sync to Notion” or “Preview”, and is sent only to your own Notion workspace. It is never sent to us.
If you buy Pro, your licence key is sent to our licensing API and to Lemon Squeezy to verify it.
No analytics, no telemetry, no advertising, no tracking, no sale of data.

What the extension handles

Data	Where it is stored	Where it is sent
Tags, colours, tag assignments, filter settings	Locally (IndexedDB / `chrome.storage`)	Nowhere, unless you export a JSON file yourself
ChatGPT conversation id, title and URL of chats you visit on chatgpt.com	Locally, so tags can be shown and filtered	To Notion, only for chats you sync
Conversation text and code blocks	Not stored by the extension	To the Notion database you chose, only when you click “Sync to Notion”. “Preview” only displays it locally.
Notion access token and target database id	Locally, in the extension's IndexedDB (not readable by web pages)	To `api.notion.com` when syncing. During “Connect Notion”, the one-time OAuth code is exchanged for the token through our API; we do not store the token.
Licence key and a random installation id	Locally	To our licensing API and Lemon Squeezy, to activate and periodically (about once a day) validate Pro

What we do not do

We do not collect browsing history; the extension only runs on chatgpt.com / chat.openai.com.
We do not send conversation content to our servers or to any third party other than your Notion workspace.
We do not use remote code, analytics SDKs or advertising.
We do not sell, rent or share personal data, and we do not use it for creditworthiness or lending purposes.

Third parties

Notion (notion.so) – receives the conversations you choose to sync. See Notion's privacy policy.
Lemon Squeezy (lemonsqueezy.com) – merchant of record for payments and licence verification. Payment card data never touches the extension or our API.
Cloudflare – hosts our licensing API. Standard request logs (IP address, timestamp) may be kept by Cloudflare for a short period for security.

Debug mode (optional, off by default)

If you enable “Debug mode” in the options and click “Download debug DOM”, the extension saves a file to your own computer containing the page structure of the last ChatGPT reply, with every text truncated to 80 characters. It is not uploaded anywhere.

Your choices

Export or import your local data as JSON from the side panel (exports never include tokens or licence keys).
Disconnect Notion in the side panel; you can also revoke access in Notion's settings.
Uninstalling the extension deletes all of its local data.

Children

TagChannel is not directed to children under 13.

Changes

We will update this page and the effective date when this policy changes. Material changes will be noted in the extension's release notes.
