Your data stays with you.
File contents are processed in browser memory, not uploaded to our servers. Convert and Merge do not save your data. Migrate saves recipe settings locally only when you ask.
Website hosting still handles normal page requests. Local processing is not a guarantee against access by someone using your device. Downloads and saved recipes remain your responsibility.
