Supplemental Guidance

Complaints, concerns, and questions from individuals can serve as valuable sources of input to organizations and ultimately improve operational models, uses of technology, data collection practices, and controls. Mechanisms that can be used by the public include telephone hotline, email, or web-based forms. The information necessary for successfully filing complaints includes contact information for the senior agency official for privacy or other official designated to receive complaints. Privacy complaints may also include personally identifiable information which is handled in accordance with relevant policies and processes.

Practitioner Notes

You need a process for receiving, tracking, and responding to privacy complaints from individuals. When someone believes their personal information has been mishandled, they need a clear path to raise the concern.

Example 1: Publish a privacy complaint email address and form on your website. Create a complaint tracking spreadsheet or ticketing system that logs each complaint, the date received, assigned investigator, resolution, and response date. Target a 30-day resolution window.

Example 2: Use Microsoft Forms to create a privacy complaint intake form, then connect it to a Power Automate flow that creates a task in Planner, assigns it to your privacy officer, and sends an acknowledgment email to the complainant within 48 hours.
