enclose
Draw a line around what is yours. Notes, keys, whispers, plans. Anything inside is held in cipher.

a quiet perimeter for what is yours
enclosure as garden
Privacy is not a fortress. It is a garden — a place that holds you while letting you breathe.
penclo encloses your data the way a shoji screen encloses a room: with a thin, deliberate boundary that admits light and refuses intrusion. Nothing leaves the perimeter; nothing enters without permission; the inside remains quiet.
The interior of the garden is not empty. The empty space is the protection.
the quiet perimeter
Each piece of data is wrapped in a thin enclosure — a kekkai, a drawn line that knows itself. Around it, only the room of your choosing.
End-to-end encryption. Local-first storage. Keys that never leave the device. There is no central garden where everyone meets; there is your garden, and only your garden.
- local enclosure — keys held only by you
- stillness by default — no ambient telemetry
- thin walls, drawn deliberately — least privilege
- open seams — auditable, inspectable, leavable
a slow, considered practice
Privacy is a habit, not a switch. penclo asks little of you and remembers everything you ask of it.
A small ritual: open the screen, choose what you keep inside, close the screen. The system breathes around your decision and does nothing more.
attend
The garden tends itself. No ambient pings, no analytics rituals. The system remains quiet.
release
Open the screen only when you choose. What leaves the perimeter is what you carry, no more.
