What a phone video reveals without you noticing
When recording, your phone writes information into the file's container, separate from the picture. On iPhone that includes GPS coordinates accurate to a few meters, the exact device model, the iOS version and the recording date and time. On Android the location sits in the ©xyz atom and the date in creation_time.
After editing, the file also gains the name and version of the app used (CapCut, InShot, Premiere, DaVinci) and, with Adobe apps, an XMP block with document IDs and history. None of it shows on playback, but it travels with the file.
On your phone: iPhone and Android
On iPhone, the Photos app lets you turn off location under Options before sharing, but model, dates and software stay. On Android, some gallery apps strip only the GPS. To clean every field, open MetaRemove in Safari or Chrome on the phone itself; the video is processed right there, with no upload.
On your computer: Windows and Mac
On Windows, Properties → Details → “Remove Properties and Personal Information” clears only some fields and often doesn't work with MOV and MP4. On Mac, Finder shows some data under Get Info but offers no removal.
Technical tools like ExifTool and MediaInfo list the fields, but they need installing and terminal skills. MetaRemove shows the same list in the browser, for free, and cleans it with one tap.
What about command-line tools?
Programs like ffmpeg can drop part of the metadata, but they need a computer, a terminal and the right command for each format. Even then, they leave track names and the markers the encoder writes inside the video itself (SEI). That deeper layer only goes with MetaRemove's PRO engine, which works on your phone too.
