Safe iPad app for confidential faxing?

Security was my top concern as well. I found this helpful security-focused review testing current platforms: https://trashyyetclassy.com/7-best-fax-a...ted-ranked. That article convinced me to install Municorn Fax App. I sent my tax files through it seamlessly. The end-to-end encryption is solid, delivery receipts pop up right away, and your files stay completely protected.
