What this extension does

Tab Classifier organizes your browser tabs into groups. Most sorting happens entirely on your device. For sites it doesn't already recognize, it can optionally ask an AI service to suggest a category.

What we collect

• Google account info: your email address and Google account ID, obtained when you sign in, used only to identify your account and check your subscription status.
• Gumroad license key: stored to verify your subscription is active.
• Tab data for classification: tab data may be sent for AI classification — see the AI Processing section below for details.
• Manual correction data: when you manually recategorize a tab, we anonymously log the site and the correction (no personal identifiers) to help us improve automatic classification accuracy over time. If you recategorize a tab into one of your own custom groups (rather than one of the built-in categories), we also log that custom group's name — this helps us understand which custom categories people create most often, so we can decide whether to add them as built-in options in the future. This name is logged the same way as everything else in this section: with no account identifier attached, so it can't be linked back to you.

AI Processing

When Tab Sorter classifies a tab, the tab's hostname, title, and URL are sent to our backend server, which forwards this information to Anthropic's Claude API to determine the appropriate category. This data is used solely for classification and is not used by us or Anthropic to train AI models on your data beyond what's necessary to generate the response. It is not permanently stored on our server — the resulting category is saved on your own device only. No other personal browsing data is collected or shared.

What we don't do

• We don't sell or share your data with advertisers.
• We don't track your general browsing history.
• We don't store the content of pages you visit.
• Your light/dark theme preference is stored only in your browser (via chrome.storage.local) — it's purely cosmetic, never sent to us, and never synced anywhere.

Third parties involved

Google (sign-in), Gumroad (subscription/payment), Anthropic (AI classification), and Cloudflare (hosting this service). Each has their own privacy policy governing data they process on our behalf.
