Is ContractCheck really free?
Yes — AGPL-3.0-or-later, no paid tier and no licence key. There is deliberately no paid companion app; the web UI is responsive, and your contract register should not depend on a second binary.

ContractCheck
One register for every contract — notice periods, automatic renewals, linked documents and yearly costs — so auto-renewals never surprise you again.
We improve this app with real-world use. Bug reports, rough edges, and ideas help — open a GitHub Issue or write to info@software-by-design.de.

- Automatic renewals with full revision history

- CSV/PDF export and an ICS feed for your calendar
- Honest scope: no e-signature, drafting, or clause management

Frequently asked questions
Does it draft, sign or review contracts?
No — and that is deliberate scope. ContractCheck is a register for deadlines, documents and costs, not a CLM suite. Pair it with your existing drafting and signature tools; it keeps the dates you would otherwise miss.
How do reminders reach us?
Via the deterministic deadline engine plus an ICS feed you can subscribe to in any calendar — cancel-by dates appear where your team already looks.
Support this app
These apps are maintained in public. If ContractCheck helps your organisation, you can fund ongoing work through GitHub Sponsors. Want a feature shipped sooner or tailored to your setup? Contact us — we are happy to discuss sponsored feature development. Product feedback — bugs, rough edges, missing pieces — is always welcome via GitHub Issues or info@software-by-design.de; it directly shapes what we build next.
Companion licences fund the maintenance, updates, and support behind the free web apps — open source is free to use, not free to build.
