Use this after the processing record changes, before a product launch, after vendor changes, or on the privacy programme's review cadence. You get three documents in a new folder, ./privacy-notice-gap-check/: a list of every place the company collects personal data and which notice covers it (collection-points.md), a table of what the notice gets right, misses or gets wrong (gap-matrix.md), and a marked-up draft of the notice changes, old text next to new (notice-redline.md). This skill drafts for a human to review and sign; this skill never marks a control effective. The privacy lead or counsel approves any change to a published notice.
Inputs to gather
Read every notice in use: the website and product privacy notice, the cookie notice, and the notices for employees, candidates and event or newsletter audiences. Read the record of processing activities, the vendor and sub-processor lists, sign-up and contact forms, and the consent tool configuration. Ask the reader, in one message: which collection points exist outside the website (sales events, purchased or enriched lead lists, partner referrals, phone support), which countries the audiences are in, and whether the processing record is current.
Step 1: map the collection points
In the collection list (collection-points.md), list every place personal data enters the company: account sign-up, contact and demo forms, newsletter, checkout, product telemetry, support channels, job applications, events, data received from customers, partners or data providers. For each, note who the people are, whether data comes from them directly or from another source, which notice covers it, and how the notice is surfaced (a link at the point of collection, or buried in a footer). Data obtained from someone other than the person falls under Article 14 of the GDPR rather than Article 13, which brings the source of the data and the timing of the information into play; mark those points clearly, because they are the most often forgotten. Check the timing too: Article 14(3) sets a reasonable period of at most one month after obtaining the data, earlier at the first communication or disclosure, and Article 14(5) holds the narrow exemptions. Note any collection point that may reach children, and the national consent age under Article 8 that applies there.
Step 2: check what the site and product really collect
With the reader, open the public site and the product in a browser and use its developer tools to list cookies, local storage and third-party requests on first load, before any consent choice, and again after accepting and after refusing. Compare with the cookie notice and the vendor list. Trackers that fire before consent are a practice problem, not a wording problem; route them to the consent tool owner. Check the consent tool as a record too: choices are logged, refusing is as easy as accepting, and withdrawal is as easy as giving consent (Article 7(3)). Non-essential cookies need consent under the ePrivacy rules whatever legal basis the notice claims.
Step 3: build the gap matrix
In the gap table (gap-matrix.md), rows are processing activities from the record and collection points from Step 1. Columns are the information items Articles 13 and 14 list, such as purposes and legal basis, the legitimate interest where relied on, recipients, transfers and their safeguard, retention, rights including withdrawing consent and complaining to a supervisory authority, automated decision-making, and for Article 14 the categories and source of the data. Mark each cell:
- Covered: the notice says it, accurately.
- Missing: the activity or item is not in the notice.
- Wrong: the notice contradicts the record or reality ("we do not transfer data outside the EU" while a support vendor sits elsewhere).
- Vague: present but not informative ("trusted partners", "as long as necessary", "to improve our services").
- Stale: describes vendors, products or purposes that no longer exist.
Also check readability against Article 12: concise, plain language, easy to find. Check that each rights channel the notice names works: the privacy lead, or a colleague they name, sends a test request through it; the agent sends nothing. Record only the outcome that person reports (day sent, relative to this check; whether an owner who could answer got it; time to answer) against the one month Article 12(3) allows.
Step 4: decide the fix and draft the redline
For each gap, decide which side moves. If the processing should not happen as it does (no legal basis, trackers before consent, a vendor without an agreement), the fix is the practice; list it for the owner and do not paper over it in the notice. Otherwise, draft the notice change in the marked-up draft (notice-redline.md) as old text, new text and the gap it closes. Prefer a layered notice: a short first layer at each collection point and the full notice one click away. Keep retention specific (a period and its trigger), name recipient categories precisely, and state the transfer safeguard actually in the contracts. Give the redline a proposed version number and effective date, and note where today's version will be archived for later comparison.
What good looks like
- The best reviewer starts with the browser and the vendor list, not the notice text, because undeclared trackers and new vendors are what a regulator finds first.
- The common mistake is polishing the notice against a generic checklist while ignoring the processing record. The tell: every item is "present", but a vendor on the sub-processor page is nowhere in the notice, and retention still says "as long as necessary".
- Good output ties every redline to a row in the processing record or a fact seen in the browser, separates notice fixes from practice fixes, and leaves a notice a customer can read in five minutes.
Framework lookups
If ISMS Copilot is connected to your agent (MCP server https://account.ismscopilot.com/v1/account/mcp), ask it the framework question with create_conversation (mode think, answer_format: decision) and keep one conversation for this task. Send only a short question in your own words, show it to the user first, and never include file contents, secrets, personal data or evidence. If it is not connected, check the official text of the framework yourself; this skill does not restate it. Set it up: https://www.ismscopilot.com/mcp?ref=grcskills-privacy-notice-gap-check
Rules
- MUST trace every gap to a processing record row, a vendor entry or an observed collection.
- MUST list practice fixes separately from notice edits.
- MUST write outputs only inside
./privacy-notice-gap-check/ and ask before overwriting.
- NEVER publish or edit the live notice; the privacy lead approves and publishes.
- NEVER describe a transfer safeguard or legal basis the contracts and record do not show.
- NEVER copy personal data seen in forms, tools or browser storage into the outputs.
