Private browsing-time insights — active time per site, trends, heatmaps, focus, and stale-tab nudges. All local. TabStyr shows where your browser time actually goes — and keeps every byte of it on your own device. It quietly measures the time you spend actively on each tab and website, then presents it as a clear, private dashboard: trends, an activity heatmap, focus scoring, category breakdowns, and gentle reminders for the tabs you've left behind. No account, no servers, and no data ever leaves your machine. FEATURES • Today at a glance — active time versus your daily average, with a sparkline. • Trends — day, week, and month views. • Activity heatmap — the hours and days you browse most, over the last 7 days. • Categories — time grouped into Work, Dev, Finance, Social, Media, News, Shopping, and Other, with hundreds of sites recognized automatically. Reclassify any site, add your own rules, or create your own categories. • Focus score — a daily productive-versus-distracting percentage, with a streak. • Top sites and per-tab breakdown — with a detail view for any site. • Daily work log — pick a day and copy a clean list of sites, or export it as an image or CSV, for standups and invoices. • Stale-tab reminders — a badge count and an optional once-a-day nudge. • Comparisons — week-over-week and month-over-month, with per-category deltas. • Export, encrypted backup, and cross-device sync — download your full history as JSON, optionally passphrase-encrypted, and restore or merge it on any device. PRIVACY TabStyr is private by default: • 100% local. All data is stored in your browser (IndexedDB) and automatically pruned to a rolling 90-day window. • No servers, no accounts, no analytics, and no ads. The extension makes no automated network requests. • It never reads page content — only the URL and title of the focused tab, which the browser already provides. • Your data stays yours: export it, encrypt it, or erase everything in a single click. There is no cloud and no backend to upload to. COMPATIBILITY Works on Chrome and other Chromium-based browsers. Available in 11 languages. Learn more at https://tabstyr.com
