TabStyr von latreon

TabStyr shows how you actually use your browser — privately. It tracks active time per tab and site, surfaces trends and an hourly heatmap, breaks time down by category and focus, and nudges you about stale tabs. Every byte stays on your device — nothing is ever uploaded.

Features
- Active time per site and per tab (not just "tab was open")
- Daily/weekly trends and an hourly activity heatmap
- Category and focus breakdowns
- Gentle stale-tab nudges to close what you forgot
- Encrypted local backup & restore (AES-GCM, passphrase-based)

Privacy
- 100% local. No servers, no accounts, no tracking.
- The extension makes zero network requests.
- Your data never leaves your device.
