Tana for cooperatives
- One systemResidents, boards, and managers work in one shared space.
- Decisions with historyAgendas, votes, minutes, and corrections stay connected.
- Requests under controlOwners, deadlines, and statuses are clear to boards and residents.
- Understandable financesBudgets, charges, payments, and documents are organised per cooperative.
- Focused communicationHouse news, chats, and documents no longer disappear between services.
When decisions get lost
A home is hard to manage when everyone has a different version of events.
Tana brings official cooperative work into one place and preserves the origin of every important change.
Decisions without a clear history
Residents cannot see who published an issue or which rules were used.
Votes cannot be checked
A chat confirmation is not an independent receipt for an accepted vote.
Work is scattered
Expenses, requests, documents, and discussions live in different services.
One working order
From the property register to a verifiable result.
- 01
Set up the property
Import units, owners, and roles with a validation report.
- 02
Work in one system

Check the history
Residents see the author, authority, version, time, and an independent receipt.

Verification instead of promises
Important information cannot be changed unnoticed.
The system states exactly what technology proves, who entered the source data, and where those guarantees end.
Visible versions
A correction creates a new version with a reason and comparison.
Author and authority
Every official action has a name, role, and time.
External witnessing
An independent timestamp is connected for pilot votes. Until then, the interface shows a clear Pending state.
Receipts
An open verifier checks evidence without signing in to Tana.
Mobile first
Residents see only the actions they need.
The PWA works like a familiar app on a phone and uses the extra space on tablets and computers without hiding functions.
- A decision is no more than two taps away
- The sync state includes an exact time
- Offline supports reading and drafts, never critical submission

Common questions
Clear about capabilities and limits.
Does an online vote have legal force?
Technical capability does not automatically make a decision binding. The cooperative's bylaws, quorum, proxies, co-owner voting, and minutes procedure must be reviewed first.
Can a published document be changed?
The original version remains in history. A correction is published as a new version with its author, reason, and connection to the previous version.
What does Tana cost?
There are no public plans yet. Cost depends on property size, required modules, and data preparation. We clarify the scope after an application.
Can Tana read private messages?
Private conversations are designed with mandatory end-to-end encryption. If all keys are lost, old history may be unrecoverable, and the interface will say so plainly.
