YSK: that the SMS app on your Android phone likely contains multiple ad trackers and requests far more permissions than it needs and you can verify this yourself in 30 seconds
**Why YSK:**
TLDR: Search for 'Exodus Privacy' - it's a nonprofit that audits Android apps and see exactly how many trackers and permissions it has. Most popular SMS apps have 6-12 trackers and 40-60+ permissions. An SMS app functionally needs far less than that.
Your SMS app sees everything. Bank OTPs, private conversations, verification codes. It's probably the most sensitive app on your phone.
Most people never think to question it because it came pre-installed or had good reviews. But good reviews don't tell you what's running in the background.
Exodus Privacy is a nonprofit that audits Android apps and publishes the results publicly. No account needed. Works on closed source and open source apps alike, it analyzes the compiled app as it actually exists on your phone, not just what developers claim.
Just search your SMS app name and see what comes up. Might surprise you. #education
