How to tell if someone went through your iPhone
You rarely get proof. Look for unexpected app states, notification history quirks, and Photos views—but focus on reducing what a passcode holder can see by vaulting sensitive files.
Weak signals
Battery drain, slightly moved icons, or open apps are noisy clues—not court evidence.
Stronger posture
Separate vault secret, empty Recently Deleted, limit notification previews, and stop leaving IDs in Screenshots.
FAQ
Is there an official viewer log for Hidden?
No. Do not rely on catching someone after the fact—reduce exposure.
