Stack Mail is an email client for Android developed by StackMail team. This connects to user's Exchange server to send and retrieve emails. We are committed to protect the user personal data.
Stack Mail is not cloud based solution our app directly connect to the user's Exchange/Office 365 Server. Even we don't know to which server user is connected to. Messages directly send and retrieved from the app to the user's mail server.
Sensitive data like user credentials are encrypted and stored locally. We never collect user's email address or any personal information.
Stack Mail by default uses SSL(Secure Socket Layer) so the data transmitted across the network is in encrypted form.
Since we are not collecting any user information for analytics purpose. StackMail will never collect any logs in background. User has to share the logs files with our support team.
