The photo is the proof. Stamp it.
Before, during, after: every job photo gets the job label, the time, and the location burned into the picture itself, so the proof cannot drift away from it. Grouped by job, out as one zip. Free, no account, and nothing uploads anywhere.
No photos yet. The label, the time, and the location get burned into each one, so the proof cannot drift away from the picture in a text thread.
The fine print, short as ever
Third gift from the people at House Calls. Photos live on your own device and nowhere else; the stamping also scrubs the photo's hidden metadata, so what it says is exactly what anyone can see on it. Location goes on the stamp only if you grant it, and a photo without GPS is still a stamped photo. Export the jobs that matter; clearing your browser clears the rest.
