@lorenzomoon Hi there, Secure Links are end-to-end encrypted so only you and the people you share with can ever see your data. Not even Proton can access it: Secure Links are generated on your device, and when recipients open the link, the browser only sends the first part of the URL (before #decryptionkey) to the Proton servers. This means Proton never has access to the content of your Secure Link.
