+This is a Magisk module to delete the leak of IMEI, MEID, UUID and FP.UID in some devices' props.
+
+## How to use
+　　Just install it in Magisk Manager
+## Is there a leak in my device
+　　Use terminal application (such as Termux) run `getprop | grep imei`
+## How it works
+　　Use `resetprop` powered by Magisk
+## Delete at an earlier time
+　　change `"$(getprop sys.boot_completed)" != "1"` to others, such as `"$(getprop gsm.sim.operator.iso-country)" != "cn"`
