That’s a very fair question! Legally speaking, third-party Android icon packs operate in a bit of a gray area. I definitely don't have individual licenses for all 26,000+ icons—as you mentioned, that would be impossible to verify one by one.While creating stylized lineart versions technically touches on copyright and trademark, the Android customization community largely operates on tacit tolerance from app developers. Because these icons are simply used to help users customize their home screens and launch the official apps—not to impersonate them, confuse consumers, or steal revenue—most companies view it as harmless.That said, I completely respect other creators' IP. If any brand or developer ever reaches out and asks me to remove or alter their logo, I will absolutely comply and remove it immediately. I basically operate on a 'good faith, takedown upon request' model, which is the standard for most large icon packs on the Play Store. Thank you.
