Photo metadata is information stored with or about an image, such as capture time, location, device details, editing history, orientation, and color information.
Private information beyond the visible picture
A photograph can disclose a location through embedded coordinates even when the scene contains no obvious landmark. Conversely, a sign, reflection, face or document number may reveal information after all removable metadata is gone. These are different disclosure paths and require different checks.
EXIF is one family of metadata. Image files may also carry XMP, IPTC, comments, color profiles, and provenance information. Removing one family should not be described as removing every possible identifier.
Inspect a copy before sharing
Start with a duplicate and inspect the actual file you intend to send. Review removable fields, decide whether provenance information should be retained, and rescan the output. Then look at the image itself. Crop or redact identifying visual details only when appropriate, and verify that the exported copy actually contains the intended change.
NullVault's photo metadata tool processes supported files locally and reports removed and preserved structures. Its documented format limits explain why some information is preserved rather than silently discarded. Keep the original when you may need capture information later.
Storage protection and sharing cleanup are different
The NullVault app encrypts its app-managed content and metadata while locked. Importing a file does not remove metadata from a copy elsewhere, and exporting can create a new readable file. Use the secure export guidance to understand that boundary. For hidden copies and prior sharing, follow the private-photo copy audit.
