Stealth Launch, LLC operates as a one-person studio in San Juan, Puerto Rico. We build our own products and provide software development services. This page summarizes how we approach privacy across our work.

Studio approach

Local-first when possible. No cloud accounts unless they add real value. We do not sell your data or track you across products. Product-specific policies explain what each app or service collects and why.

Website

If you visit stealthlaunch.com, standard web logs (IP address, browser type, pages viewed) may be processed by our hosting provider. If you email us, we receive your message and email address so we can respond.
