    Using Stacks - Viewing and Managing Pictures and Attachments

    How do I view a gallery of all the photos I’ve received or sent?

    To the right of your message list, click the Photos stack.

    Alto Files Stack

    This is your Files stack. This is where you can see all of the documents that you’ve sent or received.

    I use Alto on my mobile device. Do my stacks & settings carry over?

    Unfortunately, no. Sorry for the inconvenience. This is something that we're looking into and may add as a feature soon.

    I used the previous version of Alto for the web. Do my stacks & settings carry over?

    Unfortunately, not in the beta version. However, we're looking into ways to make this happen when we officially launch the new Alto for the web. Thanks for hanging with us as we work out the kinks!

    Privacy and Security

    How does Alto secure my data?

    To bring advances like stacks to your message list, Alto stores limited account data on secure servers. This helps make things quick & responsive and allows Alto to automatically identify information in a message to display it usefully. No cached data is shared with anyone.

    What's stored by Alto does not comprise a complete version of your email account. Your full account is only stored on your account provider's servers.

    Alto's IMAP connection uses Secure Sockets Layer encryption (SSL) and performs authentication over a secure channel. Passwords are heavily encrypted. For providers that support OAuth 2.0, Alto never sees a password. Instead, you log in directly using your provider's authentication system, and Alto then receives an access token to sign you in.

    Does AOL read my private communications?

    AOL may use information about your use of certain communication tools (for example, AOL e-mail or AOL Instant Messenger); however, AOL does not read your private online communications when you use these communication tools without your consent.

    With your consent, AOL will automatically scan data at rest in select products and services, such as Alto Mail, in order to optimize features and functionality. This may include, for example, organization of messages, reminders, suggestions or special offers.
