Rule 9: Contact Information of Person to Answer Questions About Processing
Rule 9 is short and easy to overlook, but it's one of the most commonly missed basics: every Data Fiduciary must publish, visibly, who a Data Principal can actually contact about her data.
Quick summary
What Rule 9 says
- Every Data Fiduciary shall prominently publish, on its website or app, the contact information of its Data Protection Officer, if applicable, or of a person able to answer questions about personal-data processing on the Data Fiduciary's behalf.
- This contact information must also be included in every response to a communication from a Data Principal for the exercise of her rights under the Act.
Breaking it down
Two words carry most of the weight here: “prominently” and “every.”
“Prominently” means findable, not buried. Contact details tucked into paragraph 47 of a privacy policy PDF likely won't meet a “prominent” standard. The expectation is that a Data Principal can find who to contact without hunting.
It's “DPO, or a person” — not every Data Fiduciary needs a formal DPO. Only Significant Data Fiduciaries are required elsewhere in the framework to appoint a Data Protection Officer. Rule 9 doesn't force every business to hire one; it requires publishing contact details for whoever that responsible person is, DPO or not.
“Every response” is a repeated obligation, not a one-time publication. It's not enough to have contact details somewhere on the website once. Every single reply a Data Fiduciary sends to a rights-related request must also include that contact information.
Why this rule matters
This is one of the cheapest rules to comply with and one of the easiest to accidentally miss — a stale “contact us” page that doesn't actually name a responsible person, or a rights-request auto-reply that forgets to include contact details, is a small gap that's very visible to a regulator or a frustrated user.
Real-world example
Who needs to care about this rule
- Every Data Fiduciary, regardless of size — this rule has no size or turnover threshold.
- Whoever owns the website/app footer and privacy-policy page, and whoever drafts rights-request response templates.
