If you're on Android, you can delete the app's cache manually in the main system settings

Yeah I've done that several times. It would be great if this could be automated to delete cache when I exited the app. I don't know what is saved there but it does not seem to affect my experience when I log back in after deleting the cache
It saves previews of images and that kind of stuff. Deleting it automatically after every app restart can result in worse speed (because the images have to be redownloaded every time), increased network traffic usage (same reason) and even memory wear on some devices (it doesn't really like write cycles and can break down after a certain amount of them)
Ok. That makes sense. Thanks! Maybe a timeout for the saved previews? I expect people won't be looking at the same posts again after a week or so?
You can submit a feature request on Github but I think it already has some kind of a cache cleaning mechanism implemented. If it didn't, it would grow up to 20G+
