A member can ask to be removed. Harvest handles the erasure across your church’s records.
Giving records are usually an exception. Most jurisdictions require charities to retain financial records for several years, so an erasure request does not automatically delete someone’s donation history.This is a legal question for your church, not a setting in Harvest. Take advice if you are unsure.
Every church on Harvest is separated at the database level. A member of one church cannot read another church’s people, content or giving — and neither can its admins.
