On my smartphone, I have installed Fountain without granting it any permissions. However, when I open the Contacts app and select one of my contacts, below the contact's name, along with apps like WhatsApp, I also see the option to call or send a message using Fountain.

If I try to select it, it brings up the "Open with" prompt, and choosing Fountain opens the app, but it obviously cannot send a message. It seems like Fountain treats any phone number as a clickable link.

But again, the app has no permissions. How can I fix this?
