Duka purchase
The paid promise arrives with its source.
For business
Sell a promise you can prove.
Turn a Duka purchase into controlled software, service, learning, or group access without spreadsheets.
Controlled access
Lango applies the promised doors—no more, no less.
Working group
Baraza, Darasa, and materials become available where they are owned.
Nothing hidden.
Archiving a group does not secretly revoke access. Revoking a door requires one calm confirmation. You can always see the source and the result.
