Does this app need an internet connection?
No — opening and reading .msg/.eml files works fully offline. An internet connection is only used if you choose to send feedback from the app menu.
Is my email data uploaded anywhere?
No. Your .msg/.eml files are parsed entirely on your Mac. The only exception: if you use TinyMSGViewer → Send Feedback, the message you type (and a screenshot if you attach one) is sent to our support channel.
Is this a subscription?
No. Tiny MSG Viewer is a one-time purchase on the Mac App Store — no subscriptions or in-app purchases.
Do I need Microsoft Outlook installed?
No. Tiny MSG Viewer reads .msg and .eml files on its own — Outlook is not required.
