Xmark & Your Privacy

What We Collect (and What We Don't)

Xmark is designed to work with publicly available information from your X/Twitter profile. When active, it retrieves details about your two most recent posts, or your pinned post and the most recent one. This includes:

• The text content of your posts.
• Any images or videos included in those posts.
• Your public X/Twitter user ID.

Importantly, Xmark does not access any other private information from your X/Twitter account. We only collect data that is already publicly visible on X.com.

How We Protect & Use Your Content

Your content and privacy are paramount. We employ the following principles:

• Secure Server Storage: Your complete posts (text, images, videos) are stored securely on our servers. You can access and download them anytime using a unique code generated for you.
• Blockchain Verification: A condensed, verifiable "fingerprint" (hash) of your post is recorded on the Bitmark blockchain. This serves as proof that you owned that specific content at a specific time.
• Efficient Storage: Xmark is designed to avoid storing duplicate content, which helps save storage space and resources efficiently.
• Privacy-Focused by Design: Our system is built to retrieve only the necessary public information to provide the Xmark service.

Commitment to Transparency

Xmark prioritizes transparency in all its operations. The information collected by the browser extension is limited to publicly available details from your X/Twitter posts. This same information can typically be found directly on X.com or through other public X/Twitter archiving services.

We believe you have the right to control your digital creations, and Xmark is a tool to help you do just that, securely and transparently.
