Data stays with you
Storage in your Nextcloud database on infrastructure under your control. Backups follow your existing policy — not our hosting.
Operations software that stays in your Nextcloud.
Five AGPL web apps for time, duty rosters, projects, budgets, and audio — free from the Nextcloud App Store. Companions and Check Partner support are optional.
From an idea to a working setup.
Install the free web apps, licence a companion, or talk through a custom project. One clear next step — no maze of forms.
Our apps
Five web apps. One Nextcloud. Full data control.
Each app covers a clearly defined task. Install only what you need — the apps run side by side in the same instance.

Why these apps
For organisations that need data control and traceable processes.
The apps run in your Nextcloud. Business logic and calculations stay server-side. This documentation site does not send app usage data to us.
Open source for the web apps
AGPL-3.0-or-later. You can inspect, audit, and fork the code. Using the web apps in your organisation does not require a licence fee.
No app telemetry to us
The web apps are documented for self-hosted operation without usage telemetry to Software by Design. This website uses self-hosted, cookieless analytics with an opt-out.
Three building blocks
Web apps free of charge. Companions licensed. Support optional.
The five web applications are under the AGPL: install, run, fork — without a licence fee. Official Mobile and Terminal apps are billed separately per organisation. If you want prioritised help and an annual hour pack, book Check Partner — separate from GitHub and separate from companion licences.

Deploy the web apps
Free of charge · AGPL-3.0-or-later
Install from the Nextcloud App Store or obtain the source from GitHub and run permanently on your infrastructure — without a vendor account with us and without a licence key for the web interface.
