HoYoLAB will sometimes copy your phone's clipboard contents as soon as you open the app (i.e., you'll see the Android pop-up notice stating that you pasted from your clipboard). This is done without any user interaction and without explicit permission by the user. So, if you happened to have sensitive information in your clipboard... too bad? I know some password managers use your clipboard, so your mileage may vary. I've uninstalled the app until it is patched to better protect user privacy.
