Why not just politely ask a business for their permission when you want to use their logos rather than requiring it in your ToS?
I'm disappointed because this looks _really_ nice and we're just getting starting on a new revision of our site.
If you don't want us to do so, just drop us en e-mail, and we will not and never do so.
About the background of this line: "politely ask a business" > unfortunatelly, it takes time, we are 4 young guys and are dealing with bigger companies. We were facing issues to get answers, we were losing time, and for the one and single goal to add a logo on our homepage and to help us to make a living from this startup...
If you want to be more confident about us: https://www.dareboost.com/en/about-us
That will give you a good idea of how your customers feel about this. It's probable that many people are signing up for your service and are not authorized to give you permission in the first place.
Good luck to you and your team. I'll think about sending in the email you mentioned.
But I agree that theoretically T&C allow us to do more than using logos on our own website, I'll try to find a way to add a restriction on what we can do without explicit consent.
Thanks! (my nickname is simply 'damien' in my pro email address if you want to send me directly the mentioned email)
