Remove hidden data and personal information from email attachments
MetaClean for Gmail automatically removes, adds, or modifies metadata in email attachments, preventing the leak of confidential information that occurs continuously in this type of communication and avoiding possible economic and reputational damages derived from the malicious use of metadata.

Why I should use MetaClean for Gmail?
Potential data breach: Hidden information in email attachments.
Every document contains metadata. For example, metadata is embedded in the file and is different to the information that is typed on the page – such as Author, track changes or comments. It can tell the reader who created the document, how long was spent editing it, and where the document is saved. Cleaning a document of metadata means that the recipient will only be sent what would be printed.
Removing potentially harmful forms of metadata from the attached files is a risk area that should be considered when investigating ways to prevent email-related data leaks.
