Why local-first matters for workout videos
Workout videos can expose faces, rooms, schedules, injuries, gym locations, and body movement patterns. A camera-based counter earns more trust when it can answer a practical question first: can the app count the set without requiring a remote video library?
LoopCam's current product boundary is deliberately narrow. It is an iPhone workout rep counter for supported solo sets, not a cloud analysis service, social network, or certified training system.
What stays on the phone by default
The current counter flow is designed around live camera frames, on-device body-pose evidence, and optional local recordings. If a set is recorded, the video is treated as local workout evidence unless the user intentionally exports, shares, or sends it.
What still leaves the device
Local-first does not mean every surrounding system is invisible. Apple may process App Store downloads, diagnostics, account activity, and crash data under Apple's own policies. If a user emails support, the email content and attachments chosen by that user leave the device through the mail provider.
How to test a privacy-first setup
A clean test uses one visible person, stable phone placement, usable lighting, and a supported repeated movement. The useful feedback record includes the movement, true rep count, LoopCam count, phone distance, phone height, and whether a framing warning appeared when visibility was poor.
The trust boundary is smaller than the category hype
A trustworthy camera counter should warn instead of guessing when the body is partly out of frame, lighting is weak, multiple people appear, or the movement is unsupported. LoopCam should be judged as a hands-free set counter, not as medical advice, form certification, or a replacement for coaching.
Try one controlled set
The best first test is a boring one: one person, one movement, a stable phone, clear lighting, and a manually counted target for comparison.
