Core principle of communication privacy management referring to experience with WhatsApp groups and provide practical example the principle from own experiences:

4. Co-owners need to negotiate mutually agreeable privacy rules about telling others

One core principle of communication privacy management is that co-owners of information need to negotiate mutually agreeable privacy rules about telling others. In the context of WhatsApp groups, this means that group members need to discuss and come to a consensus on who should have access to the information shared within the group.

For example, in a WhatsApp group for a group project, the members may need to discuss and agree on whether information shared in the group can be shared with individuals outside of the group. This could involve setting specific guidelines on what type of information can be shared, who it can be shared with, and under what circumstances.

In my own experience, I have been part of a WhatsApp group where we had discussions on whether screenshots of the group chat could be shared with outsiders. We decided as a group that any screenshots must be approved by all members before being shared to ensure everyone's privacy and comfort level was respected.

By negotiating and establishing clear privacy rules within a WhatsApp group, co-owners can ensure that everyone's boundaries and comfort levels are respected, and maintain trust within the group.
