Licensing
Free for open source. Licensed for everything else.
PolytopicNotch is dual-licensed. Use it under the GNU GPL v3, or under a commercial license from Tech on Tires, LLC (Polytopic Systems). Not sure which? If you won’t publish your app’s source under the GPL, you need the commercial license.
Which do you need?
| Your app | License |
|---|---|
| Open source under the GPL v3 (or a compatible license), source published | GPL v3, free |
| Closed source, paid or free | Commercial |
| On the Mac App Store | Commercial: the App Store’s terms add restrictions the GPL v3 doesn’t allow |
| In-house tools your company doesn’t distribute | GPL v3 is enough; commercial if your policy forbids GPL code |
| Evaluating, prototyping, not distributed | GPL v3, free |

A “developer” is a person who writes code that uses PolytopicNotch. Prices are per year.
What the commercial license grants
- Use PolytopicNotch in your apps and ship them in binary form without the GPL’s obligations: no need to publish your source or license your app under the GPL.
- Change the package for your apps; you don’t have to publish the changes.
- Every release in the licensed major version (for example 1.x) for the term of the license.
- Apps shipped during the term may keep shipping and updating with the versions you had.
How buying works
- Indie and Team: self-serve checkout (coming soon). Enterprise: contact us.
- The receipt and the license agreement name your company and tier. That agreement is the license.
- The package has no license keys and checks nothing at runtime.
Contributing
Issues and pull requests are welcome. Pull requests need a signed Contributor License Agreement (a bot asks on your first one), so contributions can be offered under both licenses. See CONTRIBUTING.md.
