Ok, to start this off, Day 9 of every route is still yet to come. There's no specific date so far since, you know, life can get tricky for the side of Andy (the author of this vn). This version on itch (public version) is free, no charge needed, however you can pledge for Andy's patreon to access updates earlier than the public version, as well as giving support to the author. Lastly, I can't tell you specifically how to update the android version since giving direction is not my forte, you might wanna wait for others to teach you how. I guess I covered everything HAHA hope I can help..
Oh, I see, thank yor for all this info. I didn't mean to sound like I was putting pressure or something. It's a relief to hear that they are working on it, actually. About the price, i don't mind waiting for the public version to realese. I mean, I would pay the price for sure if I had the money, but being a student without any income doesn't help at all T_T. Anyway, about the loss of progression, I hope that someone could answer that question.
Thanks, again!
