01Your account

You must be at least 16 to use MailHub. Keep your sign-in secure and tell us if you think someone else is using your account. You are responsible for activity under your account.

02Connecting mail accounts

03AI features

Summaries, the AI feed, priority sorting, reply drafts and translations are generated automatically and can be wrong, incomplete or miss tone. MailHub never sends a draft on its own. Read it, edit it, and send it yourself. You are responsible for the messages you send, including AI-assisted ones.

04Team features

When you add people to a shared inbox, channel or document, they can see what is shared there. Only share content you are entitled to share. Calls and voice messages may be recorded only where everyone involved has been told and the law allows it.

05Acceptable use

You must not use MailHub to send spam or phishing, harass anyone, access mailboxes without permission, distribute malware, infringe others' rights, or overload, probe or reverse-engineer the service.

06Plans and fees

MailHub can be used for free, with reasonable usage limits that may change as the service develops. If we introduce paid features, we will show the price and get your agreement before you are charged.

07Your content

Your mail, documents and messages remain yours. You give us permission to process them only to run MailHub for you, as described in the Privacy Policy. We do not use them to train models.

08Ending your use

You can stop using MailHub and delete your account at any time; your data is then deleted as described in the Privacy Policy. We may suspend or close accounts that break these terms or put other users at risk, and where reasonable we will tell you first.

09Disclaimers and liability

MailHub is provided "as is". We work to keep it available and accurate but cannot promise it will always be uninterrupted or error-free. Your mail stays on your provider's servers, and MailHub does not replace keeping your own records. To the extent permitted by law, we are not liable for indirect or consequential losses, and our total liability is limited to the amount you paid us in the 12 months before the claim. Nothing here limits rights you have under consumer-protection law.

10Changes

We may update these terms. We will change the date at the top and tell you in the app or by email before material changes take effect.

11Trademarks

MailHub is not sponsored by or affiliated with Microsoft Corporation, Google LLC or Apple Inc. Outlook and Windows are trademarks of Microsoft Corporation, Gmail is a trademark of Google LLC, and Mac is a trademark of Apple Inc.
