# Criteria

Each listed software has to meet following criteria:

1. Licensed as *Free and Open Source Software*
1. Source code available
1. Keeps Privacy – No Advertisement, no Spyware!
1. No proprietary elements
1. Stable (at least stable to use)
1. Actively developed, maintained or supported
1. Documentation available (Project website etc.)
1. Free of charge

F-Droid provides good [guidance](https://f-droid.org/docs/Anti-Features/) on *Anti-Features*.

Entries are sorted alphabetically.

## F-Droid links

If a package is available on [**F-Droid**](https://f-droid.org/) it can be linked using the `https://f-droid.org/app/<App ID>` URL.
If not yet, it's a good idea to promote F-Droid submission to the projects developer.

[**IzzyOnDroid**](https://apt.izzysoft.de/fdroid/) can be linked using `https://apt.izzysoft.de/fdroid/index/apk/<App ID>`, if the package is *not* marked by *NonFreeComp* or *NonFreeDepNonFreeDep*.

If the package is available on both, link F-Droid first, IzzyOnDroid second.

*Examples:*

```markdown
# Project page only: <Project>
* [**Example Project**](https://github.com/example/proj)

# F-Droid only: <Project> <F-Droid>
* [**Example Project**](https://github.com/example/proj) <sup>**[[F-Droid](https://f-droid.org/app/ex.ample.proj)]**</sup>

# IzzyOnDroid only: <Project> <IzzyOnDroid>
* [**Example Project**](https://github.com/example/proj) <sup>**[[IzzyOnDroid](https://apt.izzysoft.de/fdroid/index/apk/ex.ample.proj)]**</sup>

# F-Droid and IzzyOnDroid: <Project> <F-Droid> <IzzyOnDroid>
* [**Example Project**](https://github.com/example/proj) <sup>**[[F-Droid](https://f-droid.org/app/ex.ample.proj)] [[IzzyOnDroid](https://apt.izzysoft.de/fdroid/index/apk/ex.ample.proj)]**</sup>
```

Please do not submit other third party F-Droid repositories or Google Play Store.
