Skydeck uses multiple sources to get Caller ID information, including data directly from the cell phone companies.
If a Skydeck member has your contact information in their address book, or you call them without blocking your phone number, we will indicate to them that you are a Skydeck member and display the public information from your Profile.
If you opt in to Skydeck Caller ID, Skydeck will use the information in your address book, in addition to other sources, to verify Caller ID results for other Skydeck members. If you prefer not to allow Skydeck to use the information in your address book in this manner or you do not have the permission of your contacts as required by the Skydeck Terms of Service, do not opt in to Skydeck Caller ID.
