Guides
What your photos give away.
Every photo carries a second file inside it: where you stood, when you pressed the shutter, which phone you were holding. These guides explain what is in there, who receives it, and what you can do about it. They are sourced from vendor documentation and published testing rather than from other articles.
Guide
How do I check if a photo has GPS location data on my iPhone?
The two-second check in the Photos app, and the location fields it hides from you: altitude, compass heading, speed.
Guide
How do I remove location data from a photo on iPhone?
Apple's own share sheet method, what the Location toggle actually removes, and what it never promised to touch.
Comparison
Which apps remove EXIF data when you share a photo?
Sixteen platforms, rated by evidence quality. Includes three widely-repeated claims that turn out to be false, and four apps nobody has actually verified.
Reference
What is EXIF data in a photo?
Every field an iPhone writes, decoded, including the Apple MakerNote tags that record how long your phone had been awake and how you were holding it.
Guide
Can someone find your location from a photo you sent?
What is genuinely recoverable from a photo, what is myth, and the documented cases where metadata located someone.
Before you share
Read your own photo.
Image Inspector opens a photo on your iPhone and reads the whole file back. No account, no cloud, nothing kept.
