Software that keeps your inbox, contacts, and accounts yours.
Twindevs builds a connected suite of local-first tools — email intelligence, contact hygiene, and an account vault — engineered so the people who depend on them never lose control of their data.
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.

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 channel is opt-in. Consent decisions are recorded as immutable, timestamped events you can review and revoke at any time.
No data brokering
We do not sell or share your contact details or messaging consent with third parties or affiliates for marketing. Export your data anytime.
