Precellence
Precellence Software
Wealth planning, personal library, travel planning and home surveillance — with no Precellence account and no Precellence server. Your data stays on your devices, or in your own iCloud.
Our apps
Net worth tracker, private & offline
Track and project your net worth — 100% on your device, no bank connection. Accounts, portfolios, crypto, property and loans, projected over 10 to 20 years — inflation included.
Personal library manager
Catalogue your books by scanning their ISBN, keep your favourite quotes, and ask an AI assistant about your own collection.
AI travel planner
Plan a trip end to end: flights, hotels, activities and companions, on a timeline, a calendar or a map.
Local Mac surveillance
Turn your Mac’s camera into a surveillance station whose video never leaves the machine — detection runs on device.
Screenshots coming with the Mac App Store release.
What they share
No Precellence account, no Precellence server. OneLedger and HomeCamCheck stay on your device; Bookscout and Voyel sync through your own iCloud, which we cannot read.
Built for each platform — light and dark themes, widgets, keyboard shortcuts.
Interfaces and documentation translated, not machine-dumped.
One-time purchases where a paid tier exists. You buy the app, not a rental.
Publisher
Carefully crafted apps — privacy by design.
Precellence is an independent publisher. OneLedger, Bookscout, Voyel and HomeCamCheck are built by the same hands, with the same rule: what you put into an app stays under your control.
