# Purchasing data-use and portability rules

Updated 2026-09-19.

## Purpose

What data would a hypothetical purchasing service need, and can a member inspect, export, or delete it?

## Who uses this

Product or purchasing design lead and privacy/security reviewers

## Records to gather

Field inventory; intended uses; access roles; vendor list; retention, deletion, export, and incident design.

## Steps

1. Apply Minimum necessary intake to each proposed field and remove unrelated information.
2. Map Purpose and access plus Security and operations to accountable roles and actual systems.
3. Test the Member control and portability actions and record unmet Launch boundary items.

## Key terms

- **Data minimization**: Collecting only the fields required for the defined comparison.
- **Least privilege**: Giving each role only the access required for its task.
- **Portability**: Exporting permitted records in a usable documented format.

## Fictional example

Fictional example: A proposed annual package-count field is needed for comparison; a patient-name field has no purchasing purpose and is excluded.

## Next action

Close data-map and portability gaps before any new intake opens.

## Limits

These are hypothetical rules, not an implemented privacy program, security certification, or data-processing agreement.

## AI coaching

Help me complete this DenQAI file using the context below. Explain the supplied fictional example first, then ask one question at a time about my permitted fictional or aggregate, non-identifying inputs. Treat missing values as unknown, not zero. Keep example values separate from my case. Do not invent records, source verification, contract terms or professional conclusions. Identify the missing evidence and responsible reviewer before the next action.

Question: What data would a hypothetical purchasing service need, and can a member inspect, export, or delete it?

Records to gather: Field inventory; intended uses; access roles; vendor list; retention, deletion, export, and incident design.

Fields or sheets: Hypothetical purchasing data-use and portability rules; Minimum necessary intake; Purpose and access; Security and operations; Member control and portability; Launch boundary.

Key terms:
Data minimization: Collecting only the fields required for the defined comparison.

## AI review

Review my permitted fictional or aggregate, non-identifying draft against the DenQAI file context below. Check the actual fields, units, periods, evidence and unresolved contradictions. Use arithmetic only where the stated model supports it; a CSV has no embedded formulas. Keep missing values unknown and separate facts, assumptions and the fictional example. Return specific corrections, questions for the responsible reviewer and the next action; do not invent professional approval.
