Household Data
SitterLark is designed for two-parent households. When you join a household, both members can see and edit shared data (sitters, events, payments). If you leave a household, you lose access to that household's data.

SitterLark is not directed at children under 13. We do not knowingly collect personal information from children. The app is used by parents to manage babysitter logistics.
