Principles

Built for people who care about their data.

Not just features: these are rules every Rs app keeps, from the first line of code to release.

Offline-first

Every feature works without the internet. The network is only used when you ask for it, for example to sync.

Encrypted on your device

Data is encrypted before it is stored (XChaCha20-Poly1305, Argon2id). The keys never leave your device.

No accounts, no ads

No sign-up, no tracking, no ads. The apps don't know who you are, and they don't need to.

Native on every platform

SwiftUI on iPhone & Mac, Jetpack Compose on Android. No web views, so it feels fast and familiar.

One Rust Core

Business logic is written once in Rust, tested automatically, and shared by every platform.

Take your data anywhere

Export, back up and move devices any time with your own files. Nothing locks you in.

Technology

One Rust Core, native UI.

The app logic is written once in Rust with the Crux architecture. Each platform only draws the UI and passes actions along, so the apps behave exactly the same everywhere.

FAQ

Frequently asked questions.

Can't find your answer? Send me a message, I reply personally.

Ask me

Yes. Every core feature is free and ad-free. If a paid service such as Rs Cloud arrives later, it will be optional, and your data stays usable without a subscription.

Keep your life in order, calmly.
