Hi, thanks for the interest you demonstrate towards the project.

I answered you on Discord about security. And the HTTPS is gonna be put in place with the new site coming in a few hours. But know that the security of your keys depends on Steem Connect, we only have the access token delivered by SteemConnect who transited through our server (so only with the authorization of broadcasting a comment).

For the invalid IG account, a private IG account can not be linked to the app.
