Ask what the child is trying to accomplish
They may want to add a classmate, start a group, or use an app for an unrelated activity that happens to promote friend discovery. Ask them to show the step before the prompt. Do not assume a request during setup is essential just because it appears early. Look for a supported way to continue without sharing the address book, if one exists. Avoid entering another person’s contact details into a service merely as a test.
Consider the other people represented
An address book can contain information about relatives, classmates, and adults who are not part of the child’s new activity. Discuss that the decision affects more than the account owner. Read what the provider says about contact matching, storage, and deletion where relevant. If the explanation does not answer your question, choose a narrower supported method or wait. Do not treat a familiar app name or a friend’s recommendation as a substitute for understanding the requested access.
Keep the next step specific
If you decide to use the feature, explain what you approved and review the actual permission on the device. If you decline, help the child accomplish the original task another way when possible. Revisit the choice if the app changes how the feature works or the child no longer uses it. Follow the provider’s instructions for withdrawing access or deleting uploaded information; changing a device permission should not be described as proof that any previously shared copy has been deleted.
