What you share
Shared accounts and transactions let the family follow its common finances. Information updates on members' devices according to their permissions.

Privacy and security
Household finances can be shared. Your personal details don't have to be.
FamiDeck helps you manage family finances together while preserving a personal space. Individual accounts, private accounts and encrypted financial data support family sharing.

Shared vs private
Together for household expenses.
A space for what's yours.
Shared and private accounts serve different purposes. FamiDeck keeps them separate even within the same family space.
What stays personal
Private account details remain confidential to the owner. An account may be identifiable as existing without showing its balance or other personal details.

The ADMIN's role
Managing the family doesn't mean seeing everything.
The ADMIN manages the family space and access. This role does not automatically grant access to other members' private details.
Accounts and devices
Every member has their own sign-in.
You can sign in with email and password or with Google. Joining the family and authorizing a device are part of accessing the shared space.
- 01
Individual account
Every member uses their own FamiDeck account.
- 02
Email verification
For an email/password account, the link sent by email verifies the address.
- 03
Family invitation
The member uses an invitation or code to join the family space.
- 04
Authorized device
The ADMIN authorizes a member's device for family access.
Every member also creates and keeps their own personal recovery key.
End-to-end encryption
Cloud syncs.
Financial data stays encrypted.
Synchronized financial data is encrypted on the device before it reaches the Cloud. The Cloud does not store financial content in plain text.
On your device
Financial data is encrypted.
In the Cloud
Encrypted content is synchronized without unencrypted financial data.
On authorized devices
Data is readable according to each member's permissions.
Syncing encrypted data preserves the distinction between shared and private information.
Recovery Key
Your recovery key
is yours to keep safe.
A Recovery Key is sensitive information. It differs from your password: changing or recovering a password does not replace or change the recovery key.
Personal key
Every member manages their own PERSONAL RECOVERY KEY and must store it securely. An ordinary member receives only their personal key, not the family's recovery key or recovery code.
The ADMIN's family key
The ADMIN may also have a FAMILY RECOVERY KEY, separate from their personal key. The two keys are for different purposes: personal and family recovery.
The family key does not automatically grant access to other members' private account details.
Never send passwords, Recovery Keys or recovery codes to FamiDeck Support.
Support must never ask you to send your recovery key. Do not show it in emails or screenshots.
Offline use · Local-first
Keep going even without internet.
FamiDeck works on your device first: you can use available data and save transactions even when temporarily offline.
While offline, changes cannot be shared with other devices. Once you reconnect, FamiDeck can sync them with the family space.
Temporarily offline
Use available data and save on your device.
Back online
Changes can sync with your family.
When devices are online, shared information updates in near real time. Private transactions follow their owner's privacy rules.
Removing a member
Access ends.
Shared history remains.
When a member is removed, their access to the family's Cloud space is revoked. They no longer have access to family data.
Access revoked
The removed member can no longer access the family's Cloud space.
Shared family history retained
Previously shared history stays with the family. It is separate from the member's personal data.
Future activities disabled
Future activities and recurring transactions associated with the member are disabled where applicable.
Removing a member does not reveal their private data to the family.
Exporting data
Your data, beyond FamiDeck.
You can export data you have access to in CSV or Excel format. Exports respect your permissions and do not give you another member's private data.
Exporting data does not automatically restore it to FamiDeck: an exported file does not replace the recovery process.
Export according to your permissions
