How to Know If Your Ex Accessed Your Phone

By ForensAI Team · 2026-02-17 · 9 min

If you're asking "how to know if ex accessed my phone?" you're in a tough spot. Ex-partners sometimes have old passwords, shared devices, or access you forgot about. Research shows that around 40% of stalking cases involve a former intimate partner, and over 75% of stalking involves some form of digital surveillance—account access, location tracking, or monitoring. Getting clear answers quickly matters. Here's how to check without tipping them off, and how to get solid answers.

How to Know If Your Ex Accessed Your Phone: What to Check

Access can mean (1) physical use of your phone, (2) logging into your accounts from their device, or (3) spyware. Focus on account access first—it leaves a trail.

  • Google: Device activity and Security → Recent security activity (devices, locations)
  • Apple: appleid.apple.com → Sign-In and Security → Devices (and see where they signed in)
  • Instagram / Facebook: Settings → Security and Login → Where you're logged in / Login activity

Look for devices or locations tied to your ex—their phone, their city, or places they’ve been. If you see logins from their device or area when you weren’t there, that’s strong evidence.

Download Your Data So You Have Proof

In-app screens can change. To keep a record and run a proper check:

  • Request a copy of your data (Google Takeout, Apple, Instagram/Facebook download)
  • Don’t change passwords or log out everywhere until you’ve saved exports/screenshots if you need evidence

Then you can review the files yourself or run them through a tool that flags unknown devices, locations, and suspicious logins.

If you're in danger, contact local resources or law enforcement. ForensAI does not provide legal or safety advice.
