Active Collection of Information

We may collect certain information that you voluntarily provide to us which may contain personal information. For example, if you opt in to receiving communications from Blockstream via email, we may collect your name and email address.

If you do not want this information to be collected, you may disable cookies in your web browser.

Additionally, we may use third-party analytics services to collect and analyze data automatically collected from site users; the type and nature of those services may change without notice. Data collected this way is governed by the terms and conditions of those third party services.

Some projects, tools, forums, or other publicly-available resources associated with Blockstream may be hosted on third-party websites. Additionally, we may provide links to third-party websites for informational purposes. The privacy practices of those sites may differ from our practices, are not controlled by Blockstream, and are not covered by this Privacy Policy. We do not make any representations about third-party websites. We encourage you to review their privacy policies before submitting your personal data to such sites.
