Windows privacy agent

Every signal, under your own star.

On-device decisions, no cloud telemetry

AI traffic & LLM egress detection

OFFLINE CAPABILITIES

Productivity without interruption.

Sceptrum keeps your work flowing even when your internet fails. Everything you type is saved instantly, encrypted locally, and synced the moment your network returns—built for real-world conditions like unstable towers, travel routes, and low-end machines.

How Sceptrum behaves

What happens after you're back online.

Always catches up the moment you're back online.

When your connection returns, Sceptrum brings your dashboard back to full power automatically. Everything you created offline—edits, notes, saved pages, task updates—syncs quietly in the background without overwriting or interrupting your workflow. The dashboard simply continues as if nothing was ever disconnected.

Saved pages remain active everywhere you use Sceptrum.

Pages stored inside the app are treated as living documents. They stay available offline, update immediately as you work, and sync across your devices once you reconnect. Your workspace stays consistent and secure—no manual uploads, no reloading, no handling files.

System capabilities

Intelligence without intrusion.

Six core capabilities keep your Windows machine understandable: every signal mapped, every AI call labelled, every decision made on-device.

Unified visibility

Camera, microphone, file access and network requests, all mapped into one clear feed that makes sense in seconds, not hours.
