What the products do — not a spec list, a day.
You’re not “using an app.” You’re guarded: something knows your context, stays local, and mirrors what matters. Castle is home — your server is your desktop; thin devices are mirrors. Core is what stays with you.
Purchases & money. Guardian sees patterns — subscriptions, drift, what you forgot you paid for — without shipping your ledger to a cloud ad engine.
Food intake. Not diet police — awareness: what you ate, what you planned, what actually happened. Health. Vitals and habits in one place that belongs to you, not a platform selling attention.
Meetings & projects. Context follows you: who you’re accountable to, what slipped, what’s next — without six siloed apps that don’t talk.
Out in the world you’re guarded — briefings, boundaries, the system that learns you. At home you land on Castle: the heavy compute, the archive, the truth. Phones and laptops are mirrors; the crown stays under your roof.
Core — wearable / pocket — so something is always there: not spying for someone else, knowing you for you. Privacy isn’t a setting; it’s architecture.
