Data controller

TabSort is operated by David Kovář (IČO: 24344923), Popovice u Rajhradu, Czech Republic. Contact for privacy matters: support@tabsort.app.

What this extension does

TabSort 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.

Legal basis for processing (GDPR)

For users in the EU/EEA, the legal basis for each category above is:

• Google account info and Gumroad license key: processing is necessary to perform our contract with you (Art. 6(1)(b) GDPR) - we can't identify your account or verify your subscription without it.
• Tab data for AI classification: processing is necessary to provide the service you've subscribed to (Art. 6(1)(b) GDPR) - automatic categorization is the core function of TabSort.
• Anonymized manual-correction logs: these logs carry no account identifier and aren't linked back to you, so they fall outside the scope of "personal data" under GDPR (Recital 26) and don't require a separate legal basis.

AI Processing

When TabSort 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.

International data transfers

Anthropic, which processes tab data (hostname, title, URL) to generate classification suggestions, is a US company. This means your tab data is transferred outside the EU/EEA. This transfer relies on Standard Contractual Clauses (SCCs) approved by the European Commission.

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.

Data retention

Account records (email, subscription status) are retained as long as your account is active. You can request deletion by contacting support@tabsort.app.

Your rights (GDPR)

If you're in the EU/EEA, you have the right to:

• Access the personal data we hold about you.
• Rectification of inaccurate or incomplete data.
• Erasure of your data ("right to be forgotten").
• Restriction of how we process your data.
• Portability - receiving your data in a structured, machine-readable format.
• Object to processing based on our legitimate interests.
• Lodge a complaint with a supervisory authority. For the Czech Republic, that's the Office for Personal Data Protection (Úřad pro ochranu osobních údajů), uoou.gov.cz.

To exercise any of these rights, contact support@tabsort.app.
