When you Login with Google, the only personal information we collect is your name, email address, and profile picture associated with your Google account. When you grant us access to your Gmail Labels and Settings, we only store the Bulk Label, Bulk Filter, and the email addresses you personally add to configure the filter.
We store your information as carefully and securely as possible to prevent access by anyone except for you, and of course Gmail since it's building your labels and filters. ethermail.com's use and transfer of information received from Google APIs will adhere to Google API Services User Data Policy, including the Limited Use requirements.
ethermail.com is free for now. If people like it, we'll build an add-on premium product.
