Privacy-first.
Craft-obsessed.
402Labs is a creative technology studio. We design and ship iOS apps that respect your privacy, run on-device, and feel great to use.
Why 402Labs existsToo much modern software treats you as the product — harvesting data, demanding accounts, and shipping features nobody asked for.
402Labs started to change that. We build apps like ReyBrowse, ReyLocalAI, and GrainyCam on a simple promise: your data stays yours, intelligence runs on your device, and every detail is crafted with care.
We believe great software should feel personal, not extractive. That philosophy runs through everything we ship — and everything still cooking in the lab.
Our Core Principles
Privacy by Default
No tracking, no accounts, no data harvesting. Your data never leaves your device unless you say so.
On-Device First
AI and processing run locally whenever possible — faster, private, and yours.
Obsessive Craft
Every interaction, animation, and pixel is considered. We ship when it feels right.
Human Support
When you email us, a real engineer who built the app answers — not a script.
