When a new family registers one of its children via a form for baptism, for the awakening to the faith, for the KT... only the child benefits from RGPD consent through registration, the other members of the family do not have consent. Analyzing the database of individuals with respect to the GDPR is therefore complicated, because many parents leave without GDPR consent, even though their presence in the database was validated by them when registering their child. Would it be possible to have a RGPD mention at the household level specifying at least the last consent for its members? RGPD analysis and cleaning the base by entering through the homes would be easier. On the other hand, a search on households in relation to the last payment or the last registration in a group of one of its members, would make it possible to immediately see inactive households.
