WHY ON-DEVICE

A password only works if no one else saw the file

Sending a contract to a website to lock it defeats the point. Stripix encrypts on the device, so neither the password nor the file goes anywhere.

How your data is handled
  1. 1Turn on Airplane Mode
  2. 2Convert or clean a batch
  3. 3Every tool keeps working
