Description

This issue tracks the creation of an AnalyticsPrivacyController in the @metamask/core repository for analytics data deletion functionality. The controller will follow the same pattern as @metamask/analytics-controller and will be integrated into the Engine architecture.

Current state

The analytics data deletion logic has already been extracted from MetaMetrics class into a standalone utility module:

• app/util/analytics/analyticsDataDeletion.ts — pure functions for Segment deletion API, storage caching
• app/util/analytics/analyticsDataDeletion.test.ts — full test coverage

No migration from MetaMetrics is needed — that step is already done.

What remains to do

1. Remove isDataRecorded / updateDataRecordingFlag (dead code)

The dataRecorded flag and its two accessors (isDataRecorded, updateDataRecordingFlag) are no longer needed. The only consumer was the Settings deletion-status view, which has been refactored to work without it.

Files to clean up:

2. Create AnalyticsPrivacyController in @metamask/core

Create packages/analytics-privacy-controller/ extending BaseController with the remaining functions from analyticsDataDeletion.ts:

Controller State

interface AnalyticsPrivacyControllerState {
  deleteRegulationId: string | undefined;
  deleteRegulationDate: string | undefined; // DD/MM/YYYY format
}

Controller Actions

interface AnalyticsPrivacyControllerActions {
  createDataDeletionTask: () => Promise<IDeleteRegulationResponse>;
  checkDataDeleteStatus: () => Promise<IDeleteRegulationStatus>;
  getDeleteRegulationCreationDate: () => string | undefined;
  getDeleteRegulationId: () => string | undefined;
}

Controller Constructor Options

interface AnalyticsPrivacyControllerOptions {
  analyticsId: string;
  segmentSourceId?: string;
  segmentRegulationsEndpoint?: string;
}

3. Integrate into Mobile Engine

• Create analytics-privacy-controller-init.ts in app/core/Engine/controllers/analytics-privacy-controller/
• Create analytics-privacy-controller-messenger.ts in app/core/Engine/messengers/
• Register in Engine.ts, add state to EngineState type

4. Replace analyticsDataDeletion.ts call sites with controller

5. Remove analyticsDataDeletion.ts

Once all call sites use the controller, delete:

• app/util/analytics/analyticsDataDeletion.ts
• app/util/analytics/analyticsDataDeletion.test.ts

6. Migration: delete ANALYTICS_DATA_RECORDED from storage

see app/constants/storage.ts

export const ANALYTICS_DATA_RECORDED = `${prefix}analyticsDataRecorded`;
