~3,500 lines across 14 modules + +### Key Design Patterns + +1. **Service-Oriented Architecture**: Clear separation between control plane (provisioning) and data plane (sync/query) +2. **Dependency Injection**: All services support constructor injection for testability +3. **Privacy by Design**: Sharing profiles enforce data minimization at the core +4. **Graceful Degradation**: Backend failures fall back to local-only mode +5. **Idempotent Operations**: Upserts use stable keys to prevent double-counting + +--- + +## Privacy & Security Model + +### Sharing Profiles + +The extension implements five sharing profiles that control what data leaves the machine: + +#### 1. **Off** (Default) +```typescript +shareWithTeam: false +sharingProfile: 'off' +``` +- **Cloud**: Nothing synced +- **Local**: All analysis local-only +- **Privacy**: Maximum (data never leaves machine) + +#### 2. **Solo / Full Fidelity** (Personal Use) +```typescript +shareWithTeam: false +sharingProfile: 'soloFull' +``` +- **Cloud**: Usage + raw workspace/machine IDs + optional names +- **User ID**: Never written (personal dataset) +- **Privacy**: Readable names for personal UX +- **Use Case**: Single user wanting detailed cross-device history + +#### 3. **Team / Anonymized** (Default for Teams) +```typescript +shareWithTeam: true +sharingProfile: 'teamAnonymized' +``` +- **Cloud**: Usage + hashed workspace/machine IDs +- **User ID**: Not written (no per-user dimension) +- **Names**: Not included +- **Privacy**: Maximum for team environments +- **Use Case**: Aggregate team metrics without individual tracking + +#### 4. **Team / Pseudonymous** (Opt-in) +```typescript +shareWithTeam: true +sharingProfile: 'teamPseudonymous' +userIdentityMode: 'pseudonymous' +``` +- **Cloud**: Usage + pseudonymous user key + hashed IDs +- **User ID**: SHA-256(tenantId + objectId + datasetId) truncated to 16 chars +- **Names**: Optional with explicit consent +- **Privacy**: Stable per-user key, dataset-scoped +- **Use Case**: Per-user metrics without exposing real identity + +#### 5. **Team / Identified** (Explicit Consent) +```typescript +shareWithTeam: true +sharingProfile: 'teamIdentified' +userIdentityMode: 'teamAlias' | 'entraObjectId' +``` +- **Cloud**: Usage + explicit user identifier +- **User ID**: Team alias (validated) or Entra object ID +- **Names**: Optional with explicit consent +- **Privacy**: Minimal (user explicitly identified) +- **Use Case**: Accountability or attribution in trusted teams + +### Consent Flow + +**Transitioning to More Permissive Profiles Requires Explicit Confirmation:** + +``` +⚠️ Share workspace and machine names? + +Your usage data will be shared with teammates who have +access to this Azure Storage account. + +Choose how to identify your workspaces and machines: +○ Readable names (recommended for trusted teams) + Examples: "my-project", "LAPTOP-ABC123" + +○ Anonymous identifiers (better privacy) + Examples: "a7f3c2d8...", "5e9b1f4a-..." + +[Cancel] [Use Readable Names] [Anonymize] +``` + +**Consent Metadata Stored:** +- `shareConsentAt`: ISO timestamp when consent given +- `sharingProfile`: Profile active at time of consent +- `schemaVersion`: 3 (when consent metadata present) + +### Security Measures + +#### ✅ Secret Management +- **Storage**: Shared keys stored in VS Code SecretStorage (encrypted, per-machine) +- **Settings**: Never stored in user settings (Settings Sync safe) +- **Default Auth**: Entra ID via DefaultAzureCredential (no secrets required) +- **Redaction**: Comprehensive secret redaction in logs and error messages + +#### ✅ Authentication & Authorization +- **Primary**: Microsoft Entra ID with DefaultAzureCredential +- **RBAC Validation**: Probe entity write/delete before first sync +- **Required Roles**: + - **Storage Table Data Contributor**: Required for write operations + - **Storage Table Data Reader**: Sufficient for read-only reporting +- **Fallback**: Graceful degradation to local-only mode on auth failure + +#### ✅ PII Protection +- **Team Alias Validation**: Rejects emails (`@` symbol), spaces, common names +- **Pseudonymous Hashing**: Dataset-scoped SHA-256, prevents cross-dataset correlation +- **No Content Sync**: Prompt/response text never uploaded +- **Path Redaction**: Home directories and absolute paths never logged +- **ID Redaction**: Machine IDs and session IDs redacted in exports + +#### ✅ Data Minimization +- **Aggregates Only**: Daily rollups stored, not raw events +- **Hashed IDs**: Workspace and machine IDs hashed in team modes +- **Optional Names**: Names only stored with explicit consent +- **No Telemetry**: Extension doesn't phone home + +--- + +## Data Model & Schema + +### Storage Tables Schema + +**Partition Strategy:** +```typescript +PartitionKey: `ds:${datasetId}|d:${YYYY-MM-DD}` +RowKey: Hash(model, workspaceId, machineId, userId) +``` + +**Entity Schema (schemaVersion = 3):** +```typescript +interface UsageAggEntity { + // Partition & Row Keys + partitionKey: string; // ds:default|d:2026-01-16 + rowKey: string; // Stable hash of dimensions + + // Schema & Dataset + schemaVersion: 1 | 2 | 3; // 3 when consent metadata present + datasetId: string; // Logical isolation (e.g., "default") + + // Time Dimension + day: string; // YYYY-MM-DD + + // Core Dimensions +

Consent Metadata (schemaVersion=3) + shareWithTeam?: boolean; + consentAt?: string; // ISO timestamp + + // Timestamp + updatedAt: string; // ISO timestamp +} +``` + +### Schema Versioning + +**Backward Compatibility:** +- **v1**: No `userId` field (legacy single-user records) +- **v2**: Includes `userId` field +- **v3**: Includes `userId` + consent metadata (`userKeyType`, `shareWithTeam`, `consentAt`) + +**Forward Compatibility:** +- Readers handle all versions +- Missing `userId` treated as "Unknown" in reporting +- Missing consent metadata inferred from presence of

Why use backend sync?

+

Team visibility & insights: Share Copilot usage across your team to identify patterns, optimize costs, and track adoption. Perfect for managers, platform teams, and anyone managing Copilot licenses.

+

Multi-device sync: Work on multiple machines? Backend keeps your token usage history synced across all devices automatically.

+

Long-term tracking: Local data lives in VS Code session files that can be cleaned up. Backend provides durable, queryable storage for trend analysis and compliance reporting.

+

Privacy-first: Choose your sharing level from Solo (just you) to Team Identified (full analytics). You control what's shared and how you're identified.

How it works

+

1. Azure Storage setup: Your usage data syncs to Azure Table Storage. Daily aggregates (tokens, interactions, model) are stored per workspace/machine/day. You own the data, you control access.

+

2. Authentication: Use Entra ID (role-based, recommended) or Storage Shared Key. Your credentials stay local and secure.

+

3. Automatic sync: Every 5 minutes, the extension calculates token usage from session files and pushes aggregates to Azure. Configurable lookback window (7-90 days).

+

4. Query & analyze: Use Azure Storage Explorer, Power BI, or custom tools to query your Table Storage data.

+

Sharing profile

+
+ + + Off (local-only) + Solo + Team Anonymized + Team Pseudonymous + Team Identified + +
Choose your privacy level. Each profile controls what data is synced to Azure and who can see it.
+
+ What do these profiles mean? +
+
+
🔒 Off (Local-only)
+
Who can see: No one — data never leaves your device
+
What's stored: Nothing synced to Azure
+
Workspace names: ❌ Not synced
+
Machine names: ❌ Not synced
+
Your identity: ❌ No user ID stored
+
Use this to keep all data private on this device only.
+
+
+
👤 Solo
+
Who can see: Only you (single-user Azure storage)
+
What's stored: Token counts, model usage, interaction counts, dates
+
Workspace names: ✅ Actual names (e.g., "frontend-monorepo")
+
Machine names: ✅ Actual names (e.g., "DESKTOP-ABC123")
+
Your identity: ❌ No user ID (you're the only user)
+
Perfect for personal tracking across multiple devices. No privacy concerns since only you have access.
+
+
+
👥 Team Anonymized
+
Who can see: Team members with Azure storage access
+
What's stored: Token counts, model usage, interaction counts, dates
+
Workspace names: ❌ Hashed IDs only (e.g., "ws_a7f3...")
+
Machine names: ❌ Hashed IDs only (e.g., "mc_9d2b...")
+
Your identity: ❌ No user ID stored
+
Strongest team privacy: team sees aggregated usage but can't identify specific workspaces, machines, or users.
+
+
+
👥 Team Pseudonymous
+
Who can see: Team members with Azure storage access
+
What's stored: Token counts, model usage, interaction counts, dates
+
Workspace names: ❌ Hashed IDs only (e.g., "ws_a7f3...")
+
Machine names: ❌ Hashed IDs only (e.g., "mc_9d2b...")
+
Your identity: ⚠️ Stable alias auto-derived from Entra ID (e.g., "dev-001")
+
Track usage per-person without revealing real names. Same developer always gets same alias across sessions.
+
+
+
👥 Team Identified
+
Who can see: Team members with Azure storage access
+
What's stored: Token counts, model usage, interaction counts, dates
+
Workspace names: ⚠️ Optional: can enable actual names (e.g., "frontend-monorepo")
+
Machine names: ⚠️ Optional: can enable actual names (e.g., "DESKTOP-ABC123")
+
Your identity: ⚠️ Team alias OR Entra object ID (e.g., "alex-dev" or GUID)
+
Full transparency: team sees who uses what. Best for small teams or compliance scenarios.
+
+
+
⚠️ IMPORTANT
+
• Token counts, model names, and dates are always included when backend is enabled
+
• "Who can see" means anyone with read access to your Azure Storage account
+
• Upgrading to more permissive profiles requires explicit consent
+
• Use the "Store readable workspace & machine names" checkbox below to control name storage
+
+
+
+
+
+
+ Store readable workspace & machine names +
Applies when using Team Pseudonymous or Team Identified. Solo always includes names; Team Anonymized always uses hashed IDs.
+
+
+

Enable backend

+
+ Enable backend sync to Azure +
+
Syncs token usage to Azure Storage when enabled. Stays local-only when disabled.
+
+ Setup + Test connection + Clear settings +
+
+
+
+

Azure Settings

+

Azure Storage connection details. Use the guided wizard to auto-fill these fields.

+
+
+
+
+
+
+ +
+
+
+

Authentication

+
+ + + Entra ID (role-based access) + Storage Shared Key + +
+
+
+ Update shared key +
+
+
+
+
+
+

Advanced

+
+
Dataset ID groups your usage data. Examples: "my-team", "project-alpha", "personal-usage"
+
+
How far back to sync: 7 days = current week, 30 days = current month, 90 days = full quarter. Smaller values sync faster.
