Using Iconosquare won't compromise your ownership of your content in any way.
As an Instagram Business Partner, we are asking you for these authorizations because we need you to authorize us to display on Instagram the actions you take through Iconosquare!
For example, if you comment a post via Iconosquare, your comment will appear on the same post on Instagram, as you authorized us to display it.
It does not mean in any way that Iconosquare, as a company, will take any unauthorised action through your profile on your behalf. We will never comment or post from any of your profiles without your permission.
