Hello, I am open to discussion, and would like to thank you for taking such interest in my tool.
I've done my best to accurately describe the difference between our products. Unless I've misread, nothing you've said contradicts the content of this page.
Quest Game Tuner isn't just a copy of qgo. It serves a similar purpose, yes, but it was coded from the ground-up with many additional features and more to come.
I actually tried quite hard to set the two apart, but you updated your page shortly after my launch to mimic the marketing of my tool. QGO's page before Quest Game Tuner was very different.
Tuning: My AI is not perfect, but feedback from users has generally been positive. It generally achieves much higher than stock settings, but requires dynamic FFV / dynamic FPS to smooth over performance bumps.
Security: I'm not sure why SideQuest would treat you like that (they've always been very nice to me!) I trust Ellie (Basti564), so I'll add that info.
I didn't "copy" Ellie's code. I forked DreamGrid, which forked PiLauncher. The original creators of both now recommend LightningLauncher.
As you said, there's nothing nefarious about an accessibility service (it's a well documented feature of android) however I'm looking into making it optional as well.
Privacy: This matches what I said exactly. Thank you for confirming your use of personal emails for registration and profile sharing.
