We use TLS to protect your emails while they’re being sent, and AES‑256 encryption to keep them safe when stored. It’s the same level of security trusted by banks—so your messages stay private and protected at all times.
Zenbox connects using OAuth2, the secure industry standard used by Google and Microsoft. Your email password is never stored or seen by Zenbox—your account stays safe and in your control.
Some emails are too sensitive to share—even with AI. With Zenbox, you can mark any message as private, and it will stay on your device only. It won’t be analyzed, summarized, or processed in any way. You decide what stays local and what gets AI support.
Zenbox is built with the same high standards trusted by leading businesses. We follow GDPR and apply strict security practices across our system. Your data is handled with care, transparency, and respect. Whether you're a solo user or a large team, your privacy matters just as much.
Your emails stay private—even when AI features are used. Zenbox AI reads your messages only to help you, not to learn from them. We never use your data to train AI models or improve third-party systems. What’s yours stays yours.
When you use Zenbox AI to summarize or reply, it happens in a secure, temporary environment. Your emails are not stored permanently during this process. There’s no long-term copy, no background saving—just smart help when you need it. We prioritize privacy every step of the way.
With Zenbox, you’re always in charge of what gets shared with AI. You can choose which emails to include and skip anything confidential. Nothing is processed without your say. AI works for you—not the other way around.
Zenbox follows ISO/IEC 27001 for information security and ISO/IEC 29110 for structured software development—ensuring both your data and our processes meet global best practices.
Zenbox is built on secure, scalable cloud infrastructure (hosted on AWS) and designed for reliability, performance, and data protection. Whether you're a solo user or an enterprise team, it’s built to scale with confidence.
