}What Marsial does with Calls
Marsial publishes and schedules content on your own Calls accounts, always with your permission through OAuth, and shows you their statistics. It does not automate interactions (likes, follows or bulk messages) and does not read data from other people's accounts. You can disconnect the account at any time.
