Your life, privately filed.
Twelve quiet modules for the parts of life worth keeping track of — passwords, documents, money, meals, books, days. Everything stays on your devices. There is no account to make, no server to trust, and nothing watching.



Every module has a plain job
and a quiet name.
Each one keeps to itself, shares a spine with the others, and stays on your device. Turn off the ones you don't need; they leave without a fuss.
Seen, not described.
Drag through the rooms. Click any card to look closer.
The numbers that matter,
before you unlock anything.
Net worth, the next bill, what comes round this week — set out on the home screen the way a note is left on a hall table. Read-only, and rendered without opening the vault. Hold them in your hand on the shelf →
Two devices. Six digits.
Nothing in between.
Pair two of your devices on the same network and they keep each other in step — encrypted end to end, directly, with no relay and no rendezvous. Confirm a six-digit number on both screens once; after that, they simply know each other.
Sync does nothing until two devices agree to meet, and runs when you say so.
The six digits are derived on each device from the key exchange itself. You compare them; the network never carries them.
Each device pins the other's identity at pairing. An impostor with the right name and the wrong key gets silence.
Documents and book files transfer only when asked to — never automatically in the background.
Nothing to send.
Nowhere to send it.
decysp has no account, no server, and no analytics. A small number of optional lookups reach out when you use them — each one listed here, each one yours to turn off. That is the whole list, and it stays this short on purpose.
Sends the first five characters of a SHA-1 hash to the k-anonymity range API. No password, and no full hash, ever leaves the device.
Sends a VIN you typed to the public NHTSA vPIC API, and nothing else.
Fetches a favicon for a saved entry's domain. Sends only the hostname.
Fetches a URL you pasted, once, because you pasted it.
Software that fits like
your own handwriting.
Build colour themes from scratch, choose your greeting, reorder the home screen, switch app icons. These three ship with the app — and this page wears them too. Try one, or step into the site's own atelier →
Four platforms.
One quiet install.
No sign-up on the other side of the download — the app opens, asks you for a master password it will never see again in plain text, and gets out of the way. Try the demo vault first if you like; one tap ends it.
