Show HN: SpacerMint – iPhone storage cleanup that never touches the cloud

Hey HN, my first post here. I built SpacerMint because every storage cleanup app I tried wanted access to my photos through their servers. That felt wrong.

SpacerMint runs entirely on-device. No cloud uploads, no user accounts, no third-party analytics. Scan history lives in a local SQLite database and disappears when you delete the app.

It finds duplicates using visual fingerprinting combined with metadata (file size, dimensions, GPS, timestamps), detects similar/burst photos, cleans up old screenshots, compresses video with adjustable quality tiers, and surfaces bloat from WhatsApp/Telegram/iMessage media.

Free on the App Store. Would love feedback on the detection accuracy and anything you'd want added.
