Your measurements live in your closet. Every garment you check afterwards is one screenshot and a couple of seconds, and the whole thing is yours to export or delete.
Numbers only, editable, with the date you last confirmed them.
The brand, size, and what the verdict was, so you can look it up later.
The photo is deleted once the numbers are out, and after thirty days at the very latest. There is no gallery, and there never was.
Export the lot as a file, or delete it. Deletion reaches the backups too, because the key that decrypts your data is destroyed with it.
