I've been researching privacy tech and noticed something odd:
Camera slider cases exist (Spy-Fy, etc.) - they block physical camera access but offer no signal protection.
Faraday bags exist (SLNT, Mission Darkness, etc.) - they block all RF signals but you have to remove your phone from its case and put it in a pouch.
But nobody makes a form-fitting iPhone case that integrates both - a case you leave on your phone with a deployable Faraday shield you can toggle on/off without removing the device.
I spent some time doing market research and built out a full concept deck I'd be happy to share. The competitive gap seems real: - Current privacy case market: $30-40 camera sliders - Current Faraday bag market: $60-100 pouches - Integrated dual-mode case: Would sit at $149-249
The use case seems obvious: people who want on-demand full privacy (cameras + signals) without the friction of removing their phone from a case and putting it in a bag.
So my question for the HN community:
Why doesn't this exist?
Is it: - Engineering impossible? (Can't get proper RF seal with a deployable mechanism?) - Market too niche? (Demand overlap between camera privacy and signal blocking too small?) - Someone tried and failed? - Legal/regulatory issues? - I'm just missing something obvious?
I'm not looking to build this (no hardware experience), just genuinely curious why this white space exists.
