Privacy-first by design

Software that keeps your inbox, contacts, and accounts yours.

A connected suite of local-first tools — email intelligence, contact hygiene, an account vault, and the infrastructure behind them — engineered so the people who depend on them never lose control of their data.

The Twin suite

Five tools, one privacy standard.

Each product runs local-first and shares one consent and security model. Use one or all — your data stays on your terms.

How we treat your data

Privacy is the product, not the tax.

Local-first

The core of each product runs on your device. Cloud features are opt-in, disclosed, and shown to you before anything leaves your machine.

Explicit consent

Every notification and cloud action is opt-in. Consent decisions are recorded as immutable, timestamped events you can review and revoke.

No data brokering

We don't sell or share your contacts or messaging consent with third parties or affiliates for marketing. Export your data anytime.
