ColdFlow is a private tool used by a single person, its operator, to write and send one-to-one business emails from mailboxes the operator controls. It is not offered to the public.
When the operator connects a Google mailbox, ColdFlow asks Google for these permissions on the operator's own account:
gmail.send): to send the emails the operator writes from that mailbox.gmail.readonly): only to detect replies to the emails that were sent and delivery failure notices (bounces), so that follow-ups stop when someone answers or an address does not exist.openid, email): to show which mailbox is connected.ColdFlow's use and transfer to any other app of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
The operator emails business contacts to propose a professional conversation, stores their name, email address and business details, and stops contacting anyone who asks not to be contacted.
To ask for access to, correction of, or deletion of your personal data, or to object to its processing, contact the operator at the support email address shown on Google's consent screen when a mailbox is connected, or reply to any email received from the operator.
Data travels over HTTPS, access to the application requires a password, and stored credentials are encrypted.
