Document GPS is a free Chrome add-on developed by ShelterZoom. It offers a secure and efficient way to track, modify, and delete attachments sent via email using blockchain-based security. With Document GPS, you can have complete control over who can access, download, and share your email attachments.

One of the key features of Document GPS is its blockchain-secure system, which ensures that your attachments are fully protected. You can give or revoke permission to recipients, allowing them to access, download, or share your attachments. This eliminates any worries about unauthorized access to your files.

Document GPS provides a timestamped log for each document, showing real-time activities such as views, shares, downloads, and permission changes by individual users. This gives you complete visibility and control over who sees your files. Additionally, the add-on offers the option to send files securely without tracking recipients using the GENERAL ACCESS feature.

The add-on also encrypts all files sent through Document GPS, providing an extra layer of security even if the email itself is not encrypted. It seamlessly links the desktop and mobile app, allowing you to track your files on the go and revoke access from any device.

Document GPS offers a free trial without the need for a credit card. It also provides a Private Library where recipients can securely upload files with immediate tokenization and encryption. This feature is especially useful for professionals in healthcare, finance, law, research, and more.

With Document GPS, you can have peace of mind knowing that your attachments are protected by blockchain security. Its intuitive interface and comprehensive features make it easy to manage and monitor your documents effortlessly.
