File conversion is done on a secure, encrypted conversion server instead of on your phone. There are a few reasons for this:

- A lot of types of conversions can not yet be done on smartphone processors.
- Converting large files (especially videos) on a phone would use an incredible amount of battery and may cause overheating
- We do not need to write separate conversion software for different smartphone operating systems, they can all use our same software on the server.

Your privacy is our #1 priority - your files are stored on encrypted cloud servers while they are converting and they are deleted immediately when your conversion is either complete or cancelled. We keep no permanent records of individual conversions, and your file is renamed before upload, so your filename is never sent over the internet at all.
