Personalized Profiler

100% local browsing personas, trends & privacy analytics. Your data never leaves your device.

Personalized Profiler turns your browsing history into an interactive picture of how you actually spend time online — computed entirely on your own device. Unlike every other analytics tool, this extension has no servers, no accounts, and no telemetry. It makes zero network requests. Nothing you browse ever leaves your computer, and you can verify that yourself in DevTools. WHAT YOU GET • Browsing persona — Ten data-driven personas (Full-Stack Builder, AI Explorer, Deep Scholar, Streaming Aficionado, Social Connector, Market Strategist, Productivity Maven, Creative Designer, Deal Hunter, Night Owl Gamer) scored from your real category mix, with a secondary "hint of" trait. • Shareable persona card — Export your persona as a polished image, rendered locally on canvas. Share it if you want to; nothing is uploaded. • Trends over time — Switch between 7, 30, and 90-day windows and see how each interest category is shifting compared with the previous period. • Accurate activity heatmap — A 24x7 map built from real per-visit timestamps, not estimates, so you can see exactly when you browse. • Digital wellbeing insights — Peak activity hour, most active day, late-night browsing share, and your deep-work focus hours. • Privacy inspector — See which domains store the most cookies, and the split between Secure, HttpOnly, session, and persistent cookies. • AI context profile — Generate a paste-ready "about me" summary of your interests and tools for Claude or ChatGPT custom instructions. Built on-device with per-section toggles, so you choose exactly what to include. • Five themes — Follows your browser's light/dark setting automatically, or pick Dark, Light, Minimal Dark, Minimal Light, or Rainbow. YOU CONTROL EVERY DATA SOURCE Only browsing history and top sites are used by default. Cookie, download, and bookmark analysis are entirely optional and off until you switch them on. Turn any source off and its data is deleted from the extension on the next refresh — your actual browser data is never modified. Built-in Privacy Policy, Terms of Use, and a Data Transparency page show you exactly what is read, where it is stored, how long it is kept, and how to erase it.
