The app. is used as a standalone Zip/Unzip application for all the files that are stored in your PC or in peripheral storage (such as optical discs, removable storage, usb flash memory, etc).
The files are transfered only to the RAM (the temporary memory of your PC) during accessing the contents. When you close the app the memory is cleared and we don't collect or save anything else. No extra info about the file type, the encryption method, or anything else is collected, stored, shared.
All your personal preferences, file access history, language selection preferences, etc. is never collected from the app, nor is distributed to any other third party outside the app. Everything that you do is stay inside the app.

When you close the app, then the password is forgeted!
