Local-first
Your library and progress live on your device and work fully offline. Cloud sync is optional, and always to your own account.
Atlas Runtime Labs
Calm, durable software for the way you read & focus.
We design quiet tools that respect your attention and your data — local-first by default, beautifully built, and made to last.
What we do
Tools that earn their place on your home screen.
Atlas Runtime Labs is an independent studio. We ship a small number of focused apps and maintain them properly — no dark patterns, no data harvesting, no noise.
Private by default
No ads, no trackers, no third-party analytics. We don't build profiles, and we never sell data — because we never collect it.
Crafted to last
Considered typography, an accessible IBM Carbon interface, and an obsession with the small details of everyday use.
Featured
Dynamis — your reading library, done right.
A fast, distraction-free EPUB & PDF reader with reflow-proof highlights, fully customizable typography, light/dark themes, and optional Google Drive sync to your own account. Built on everything above.

How we build
Four commitments behind everything we ship.
01
Your data is yours
Content stays on your device. When you opt into sync, it goes to your own cloud storage — never to a server we control.
02
No surveillance economy
We don't embed ad networks or analytics SDKs. Our apps make no money from watching what you do.
03
Works offline, forever
An internet outage should never get between you and your library. Connectivity is a feature, not a requirement.
04
Designed for everyone
Readable type, strong contrast, keyboard and screen-reader support, and respect for reduced-motion preferences.
