Private coordination for trusted groups
SiloKeep is a local-first coordination tool for small trusted groups — shared rosters, responsibilities, calendars, and action items — where sensitive information never lives in a readable cloud.
Track who's in your group and what each person is responsible for — assignments, roles, and confirmations at a glance.
Coordinate dates — including recurring events — and share a single calendar with other groups without exposing anything else.
A live, shared task list so nothing falls off the radar — updates merge across devices, even offline.
A shared notebook for your group. Several people can type in the same note during a meeting — edits merge as you go.
The difference
Most tools promise privacy in a policy you have to trust. SiloKeep makes it structural — the same posture as an end-to-end encrypted messenger, applied to your group's coordination.
Every member's device holds the full data set and works fully offline. There is no central database of record to lose or leak.
Only intended members hold the keys. The sync server — even hosted — only ever sees ciphertext. It cannot read your data.
Sharing is structural, not a checkbox. A calendar shared with another group can't expose your private roster — the keys were never shared.
Identity is self-sovereign: an account is derived from a recovery phrase, with biometric unlock coming. There's no central account table to breach.
Every member's device holds the complete data. Stop paying, switch tools, or walk away — your group's data stays with you, never stranded on a server.
Because no server can read your data, a server breach exposes nothing readable. Revoking a member cuts off all future access.
Add people, assignments, and tasks. Everything is stored locally and works offline.
Changes merge across your group's devices as encrypted, unreadable data.
Our sync relay passes the encrypted data along. It holds no keys and no accounts — there's nothing on it to trust, and nothing readable to breach.
SiloKeep is free to use on your own device. One flat subscription — per group, not per person — unlocks encrypted sync for everyone in it.
$0
$20 / year per group
Cancel anytime — your group keeps syncing until the period ends. And because your data lives on your devices, not our servers, stopping a subscription never takes anything away from you: it's yours to keep, sync or no sync.
Set up your group in minutes. Invite the people you trust. Keep the data to yourselves.
