Before sending, check that the response answers every requested item, contains only the requester's personal data, protects another person's rights and protected secrets, and explains any partial result. Keep the original request, verification, searches, analysis, response, disclosed copy, action evidence, and delivery proof.
When the controller corrects, anonymizes, blocks, or deletes data, it must inform agents with which it shared the data so they can repeat the action, unless communication is proven impossible or involves disproportionate effort. Record the recipients contacted and the exception analysis.
Use a separate decision row for each requested right and data set. A response may therefore be fulfilled for correction, partially fulfilled for access because another person's data was separated, and refused for deletion because a documented Article 16 conservation ground applies. State the facts and legal reason for each outcome.
