Open MSG does not collect any data.

Your emails and attachments are opened, converted and saved on your Mac. Nothing is uploaded to us or anyone else.
No analytics, advertising identifiers, tracking or accounts.
Remote pictures in an email are blocked until you choose Show Pictures. If you do, your Mac loads them from the sender's image servers, as any email app would.
JavaScript in emails is disabled. Links open in your browser only when you click them.
Purchases are handled by Apple through the App Store. We never see your payment details.
