Everything, organized
Six areas cover the parts of life worth keeping track of — pick your dynasty back up wherever your household left off.
Treasury
Assets, commitments, credit cards, and subscriptions — one ledger for the whole dynasty.
Household
Your residence, energy, meals, maintenance, and belongings, all tracked in one place.
Health Center
Health care, food, sleep, and safety — the essentials, kept in view.
Baseline
A dashboard of status indicators — how well every domain of your life is holding steady.
Academy
Guided roadmaps for the milestones that matter — buying a home, building an emergency fund, and more.
Possessions & Properties
Inventory everything your household owns and everywhere your household lives, down to the room and the drawer.
How it works
Three steps, and nothing your household enters ever leaves your device unencrypted.
Sign in with your email
No password to invent or forget. We send a 6-digit code — enter it and your household is in.
Set a dynasty password
This unlocks your data, on-device. It's never sent anywhere, and we can't reset it for your household — that's the point.
Everything stays local
Your records are encrypted with the Web Crypto API and live in your browser's storage, not our servers.
Built local-first, on purpose
Your financial and household records are stored in your browser, encrypted with a password only your household knows. We only use a hosted account to sign your household in with a one-time email code — the dynasty data itself never touches our servers, so there's nothing of yours for a breach, a subpoena, or an ad network to find.
