Fax app security

Hi! I’m thinking about using a free fax app for sending documents from time to time. I’ve read different opinions online and now I’m unsure how safe these apps really are. What should I realistically worry about as a regular user?

Hello! I learned more about this on the platform liveballot.com after reading the article “Free Fax App Alert: 5 Privacy Risks to Avoid”. It explained that free fax apps may store documents longer than users expect, collect metadata, and sometimes share information with third parties. Some services don’t clearly state how files are deleted or protected. This helped me understand that convenience often comes with privacy trade-offs, especially when no payment is involved.
