Is my email private? How MailOver protects it
Your email is stored with zero-access AES-256-GCM encryption, so MailOver cannot read your mail and staff cannot open it. Privacy filters skip any sender or keyword you mark private before the AI ever sees it, and we never sell your data or train AI models on your email. You can export or delete everything at any time.
How your stored mail is protected
Yes, your email is private. The mail MailOver syncs is stored with zero-access AES-256-GCM encryption, using a key derived just for your account. In plain terms, MailOver cannot read your mail, and our staff cannot open it. The full mechanics are in AES-256 zero-access encryption, explained.
We also never sell your data, and we never use your email to train AI models. The AI reads your mail for one reason: to build your Action Items, Highlights, and FYIs. That is it.
Privacy filters run before the AI sees anything
Some mail you may not want touched by AI at all. MailOver handles that with privacy filters that run before any processing happens. You can mark specific email addresses as private and add private keywords. When a new message matches one of those, it is skipped entirely: it is never sent to the AI, never briefed, and no Action Items, Highlights, or FYIs are extracted from it.
This filtering happens up front, so a private message does not get read first and filtered later. It simply does not enter the AI pipeline. A privacy stats view in the app shows you how many messages were blocked this way, so you can see the filters working.
Set a private sender or keyword
Open your privacy settings. Go to Settings and find the privacy filters, where you can add private addresses and private keywords.
Add a private address or keyword. Enter an email address you want kept out of AI, or a word that should always be treated as private, then save it.
Matching mail is skipped from then on. New messages that match are left out of processing automatically. You can review or remove your filters any time, and the privacy stats view shows how many messages have been blocked.
You stay in control of your data
Whatever is stored, you can take with you or remove. A one-click JSON export gives you a machine-readable copy of your data, and you can delete it whenever you want.
