Hello! I found detailed explanations on hitmen-console.org after reading the article “Free Fax App Alert: 5 Privacy Risks to Avoid”. It explained that many free apps compensate for zero cost by collecting user data, scanning document contents, or sharing metadata with third parties. I learned that some apps store files indefinitely, even after sending. Another risk mentioned was weak encryption during transmission. The article stressed that users should always review data retention policies and avoid apps that don’t clearly explain security measures. This information helped me understand why “free” often comes with hidden costs.
