How We Disclose Your Information

We share your personally identifiable information only in the limited circumstances below. Zbox never sells your information or shares it with third-party advertisers.

With your permission. We may share your information with your consent, after letting you know what information will be shared and with whom.

In response to the law. We may disclose your information if we believe it is reasonably necessary to comply with a law, regulation, or valid legal process. If we are going to release your information, our policy is to provide you with notice unless we are prohibited from doing so by law or court order (e.g., an order under 18 U.S.C. § 2705(b)). We may disclose your information without giving you prior notice if we believe it’s necessary to prevent imminent and serious bodily harm to a person. Nothing in this policy is intended to limit any legal objections or defenses you might have to demands to compel disclosure of your information, including demands from the government.

With third parties helping us provide Zbox. We may share your information with third-party services helping us provide our products and services. Those third parties access and use the information we share with them only on our behalf. They include Amazon, Google, and Stripe. Please note that this Privacy Policy explains Zbox’s practices only, and doesn’t cover the practices of other services. Take a look at those companies’ privacy policies to learn more about their data practices.

  • A cookie is a small amount of data, which often includes an anonymous unique identifier, that is sent to your browser from a web site's computers and stored on your computer's hard drive.
  • Cookies are required to use the Zbox service.
  • We use cookies to record current session information, but do not use permanent cookies. You are required to re-login to your Zbox account after a certain period of time has elapsed to protect you against others accidentally accessing your account contents.

Account Termination

You can disable your Zbox account at any time by signing in and canceling it online. This means your user account will no longer be active on our service, and your data will be automatically deleted in the normal course of business with no further notice to you.

Data Security

Zbox service are designed to have several layers of security.

We encrypt files on client side before you upload to Zbox servers. We use the AES-256 or XChaCha20-Poly1305 algorithm. You control your encryption keys, and Zbox does not have access to them.

We use Secure Sockets Layer (SSL)/Transport Layer Security (TLS) to create a secure tunnel to protect data in transit between your apps and Zbox servers.

We don’t store your account passphrase on our servers in any form. Your passphrase is only on your device, and we hash and salt it to help protect it against possible compromise.

We limit the number of Zbox employees who have access to user data through policy and technical access controls.

No transmission over the internet is completely secure, so we can’t absolutely guarantee that unauthorized parties won’t be able to defeat our security measures. You use Zbox at your own risk, and are responsible for taking reasonable measures to secure your account (such as choosing a strong, unique passphrase and keeping it secret).

We are always on the lookout for vulnerabilities in Zbox. If you discover a vulnerability in our service, we would be grateful for your report and encourage you to let us know immediately. If you give us reasonable time to respond to your report before making any information public, and make a good-faith effort to avoid privacy violations, destruction of data, and interruption or degradation of our service during your research, we will not pursue any legal action against you or ask law enforcement to investigate your actions.
