F-Droid is application & app store for android apps (alternative to Google Play) that accepts only FLOSS (free/libre and open-source) apps and doesn't require any account creation/login in order to download apps.

The requirements for being included into f-droid are here: https://f-droid.org/en/docs/Inclusion_Policy/

The process for getting an app published to f-droid is outlined here: https://f-droid.org/en/docs/Inclusion_How-To/ https://gitlab.com/fdroid/rfp#submission-queue https://gitlab.com/fdroid/fdroiddata/blob/master/CONTRIBUTING.md

You can open a RFP (Request For Packaging) ticket here: https://gitlab.com/fdroid/rfp or an user can do so, provided you agree to include this app in F-droid (a comment to this issue is enough for it)

Some users don't have play-store on their devices as they are degoogled devices or don't create/use google account (using aurora store app https://auroraoss.com/ in anonymous mode (which is available on f-droid) is solution to still get apps from google-play) or using OS/custom ROMs that don't have it included, such as: (Some bundle f-droid by default)

https://grapheneos.org/ GrapheneOS
https://calyxos.org/ CalyxOS
https://lineageos.org/ LineageOS
https://lineage.microg.org/ LineageOS for microG

Downloading APKs from official places like github releases or website, or from unofficial sources like APK downloading sites https://apk.support or https://apkpure.com/ etc... will avoid the play-store/google dependency but it's lack automatic update mechanism unless it's built in into the application, F-Droid solve this.

Once the app is published into f-droid add the below image code into
README.md to show that the app available on f-droid:
