You can patch some reddit apps like Sync and use your own api key. Even if you don't browse reddit, it's nice to be able to open the occasional link in a pleasing UI.
I also don't understand this. If I have my own, personal API key, and supposedly I can use it for free. Then if I write my own app, without releasing it on Play Store, I can't use it with my own API key? Why not? Is there any mentioning of this explicitly against the rules?
Afaik I can request my key on Reddit. Then I, all by myself, create an Android app for myself, completely from scratch, never release it to anywhere, just have it on my phone. So not Revance an existing , seriously program one from zero. It would be personal use, would it not?
Good question. Those API keys are supposed to be unique to the app using it. Patching in your own isn't something you're supposed to do, but it is indeed possible
Some apps taking serious steps towards a subscription model have been granted extra time by reddit. There were conditions, but there were at least a few of them (Infinity and Relay are the ones that come to mind, but there was at least one more that I can't remember right now).
