Get Fake Calculator old version APK for Android
사진을 숨길 수있는 가짜 계산기
The calculator functions as normal ones, but after you hit "clear" key followed by a "%" key, you will enter a secret place where you can upload one image(one image so far, It will hide more pictures), and hide it in the cloud. Pictures will upload to Google firebase, so please don't upload any private picture yet, I am still working on the privacy feature.
