Privacy note
Threadback is zero-upload and telemetry-free. This page restates that promise and explains the only two outbound requests.
No conversations or queries collected
The extension never collects, stores, or forwards your conversation content, search queries, or usage statistics. Conversations and the index are kept only in your local browser.
Outbound request 1: one-time semantic model download
When you enable semantic search, the extension downloads a semantic model that runs locally in your browser (only the model files are transferred — never any conversation or query): it tries Hugging Face first and falls back to our mirror if unreachable. After download, semantic search runs fully offline on your device; this request never happens if you don't enable semantic search.
Outbound request 2: license check
Only when you actively activate / re-validate / deactivate Pro does the extension contact the license service, and the request body contains only your License Key and a locally generated anonymous device id (instanceId) — never any conversation, query, or personal information.
Payment info never touches us
Checkout, payment methods, invoices, taxes, and refunds are all handled by the Merchant of Record (Dodo Payments). We never see or store your card number or billing address.
We store only three kinds of business data
To issue keys and manage devices, the server persists only the License Key, anonymous device id, and purchase email — never any conversation, query, or usage data.
No third-party tracking
Neither the website nor the extension includes any third-party analytics or ad scripts.
