Who sees my profile details?
No one has direct access to your (contact) details. There are 2 ways in which organizations can still see part of your details and contact you:
1. Your profile is set to public
Organizations can then find you and view your profile. This only contains information about your desired volunteering activity — no contact details. They can send you a message via the contact form on the website. Only when you respond to that will they see your contact details.
2. You show interest in an activity yourself via the contact form
In that case, the organization automatically receives your message, your email address, and information about your desired volunteering activity so they can contact you.
