What information does Facebook use to show me content about voting and elections?
On Facebook, we use your age (18+) and location data to show you reminders about election-related information, such as registration, vote-by-mail and Election Day reminders, in your state or voting district.
You may have added or be asked to provide your street address and/or state to receive more specific information about voting. Providing your address is optional and isn’t displayed to other people on Facebook. If you choose not to provide your street address and/or state, you may receive voting and election reminders based on your primary location.
Keep in mind, the information you provide may also be used in other Facebook features, including features about government, voting and elections.
