Verify mobile uploads strip EXIF GPS

Original: Prove Your Mobile Upload Removed EXIF GPS Before the Retry Queue Keeps a Copy

Short summary

A testing protocol for verifying that mobile photo uploads strip EXIF GPS metadata before files enter retry queues. The approach uses synthetic JPEG/HEIC fixtures with known metadata and intercepts uploaded bytes at the server level, not just the UI preview. Key checks include background retry paths, app restarts, thumbnail caches, and cloud backup exclusion of temporary files.

  • Use synthetic JPEG/HEIC fixtures with known metadata—never personal photos
  • Intercept uploaded bytes at the server to verify GPS and timestamp removal
  • Check retry queues, app restarts, thumbnails, and backup exclusion for residual originals
