Our Approach

Abstract background representing local-first design — Local-first whenever possible.

**We avoid servers, telemetry, and external dependencies.** Most of our tools work fully offline, and when a feature requires connectivity, it is explicit, minimal, and always under the user's control.

Abstract background representing privacy — Privacy without compromise.

**No analytics, no tracking, no profiling.** When cloud sync is offered, it is user-owned and encrypted, such as iCloud. We never collect personal data or build identity profiles.

Abstract background representing performance — Performance and simplicity.

**Rust, C++, Swift, and native development where it matters.** We write software that remains fast, predictable, and easy to understand — no unnecessary layers, no bloat.

Abstract background representing long-term reliability — Tools designed to last.

**We build focused tools with long-term stability.** Clear architectures, minimal dependencies, and a refusal to rely on fragile third-party infrastructure.

Built on real engineering

We build focused tools with a simple principle: do one thing well — and do it right. Local-first, private, efficient, and designed to last.
