Problem

Anonymous analytics could only be disabled through an environment variable. Users should also be able to opt out from desktop, web, and mobile settings without restarting the server.

Change

Adds an Anonymous analytics toggle in desktop/web General settings and mobile Maintenance settings. The preference persists per environment and participates in shared settings across connected environments. When selected environments have different saved preferences, the first click or tap turns analytics off for all selected environments without temporarily enabling it on environments already opted out.

Turning analytics off stops recording and delivery of server and client usage events and discards buffered events and pending retries. Re-enabling starts fresh without replaying discarded events.

Opt-out also handles rapid off/on changes and sends already in progress: an existing request may finish, but its result cannot restore discarded events or continue sending the old queue. The telemetry gate is loaded once at startup and updated from persisted settings changes, so recording events and flushing batches do not reread settings or materialize secrets. Opt-out discards the queue directly from that settings stream, without waiting for secret-store I/O.

T3CODE_TELEMETRY_ENABLED=false still takes precedence. Controls explain the override and show a disabled mixed state when selected environments have different override states. Mobile also explains that this setting must be changed with All projects selected.

Analytics remain enabled by default, and collected events are unchanged. Also validates analytics batch and buffer limits and checks retry backoff after acquiring the flush lock.

Scope and approval

This configures the existing analytics capability, which already supports an environment-variable opt-out. The setting controls that same collection and delivery behavior without adding new collection, changing which events are collected, or changing the default.

Closes #4123.

Follow-up to the analytics disclosure fixes in #16563, #16564, and #16565.

Verification

Earlier validation passed 176 tests covering persistence, settings sharing, opt-out, discarded queues and retries, and re-enabling. The final telemetry changes pass all 8 focused tests, including a regression check that recording and flushing read settings only once at startup and that saved settings cannot override an environment-variable opt-out. Server, web, and mobile typechecks passed. Formatting and targeted lint passed with existing lint warnings.

Tested the toggle in the web client and iOS simulator. Mobile changes persisted on the server and appeared immediately in the web client. Checked enabled, disabled, mixed, and overridden states, including the disabled controls and override notices. The final mixed-preference click/tap change was typechecked but was not retested in a live client.

Desktop and native iOS builds passed, along with iOS/Android JavaScript exports. Android was not built natively or tested on a device.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR adds a cross-platform anonymous-analytics opt-out that changes persisted settings, environment synchronization, and server telemetry buffering and delivery behavior. An unresolved Medium-severity finding also indicates queued events may survive an opt-out and be sent after re-enabling telemetry.

Not approved because:

📝 Walkthrough

Walkthrough

The changes add a persisted telemetry setting that controls server analytics, expose its state and environment overrides in web and mobile settings, and update telemetry documentation. They also add an Android mapping for the chart.bar symbol.

Changes

Telemetry controls

Layer / File(s) Summary
Telemetry setting and shared-state contract
packages/contracts/src/settings.ts, packages/client-runtime/src/state/sharedSettings.ts, packages/client-runtime/src/state/sharedSettings.test.ts, packages/contracts/src/server.ts
ServerSettings now includes telemetryEnabled, defaulting to true, and patches can update it. Shared settings include the value in patches and comparisons. ServerConfig adds an optional environment override indicator.
Persisted settings and analytics enforcement
apps/server/src/serverSettings.ts, apps/server/src/serverSettings.test.ts, apps/server/src/telemetry/AnalyticsService.ts, apps/server/src/telemetry/AnalyticsService.test.ts, apps/server/src/server.ts, apps/server/src/device/DeviceService.test.ts, apps/server/src/orchestration-v2/ThreadSettlementService.test.ts, apps/server/src/provider/*, apps/server/src/terminal/Manager.test.ts
ServerSettingsService adds a persisted-settings change stream. AnalyticsService gates recording and sending on environment configuration and the persisted setting, and replaces its queue when telemetry is disabled. Tests cover persistence, opt-out behavior, in-flight sends, and settings-service mocks.
Client controls and environment overrides
apps/server/src/ws.ts, apps/web/src/components/settings/SettingsPanels.tsx, apps/web/src/components/settings/settingsSearch.ts, apps/mobile/src/features/settings/SettingsServerControlsRouteScreen.tsx, apps/mobile/src/features/settings/components/SettingsSwitchRow.tsx, docs/user/telemetry.md
Server configuration reports environment-level telemetry disablement. Web and mobile settings display the telemetry control and override state. Search and documentation describe the setting.

Mobile chart icon

Layer / File(s) Summary
Android chart symbol mapping
apps/mobile/src/components/AppSymbol.tsx
The Android SF Symbol lookup maps chart.bar to IconChartBar.

Merge Risk: 🔵 Low · up to 5e185

The anonymous analytics opt-out behaves as described. One small code-organization cleanup in the server config handler is worth doing, but it does not affect behavior.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 5e185

The change improves users’ control over analytics while preserving existing permissions and the environment-level disablement override. No introduced authorization bypass or verified privacy defect was established. Concurrent opt-out completion and downgrade behavior remain areas of uncertainty.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • observed — The preference is environment-owned, not per-user consent. A settings-authorized writer can affect analytics for every user of that environment. Client target planners restrict ordinary writes to selected connected environments; each environment’s server connection remains the authorization boundary.

Trust Boundaries and Controls

  • observed — The client-controlled boolean enters the existing settings RPC. Patch classification requires AuthSettingsWriteScope, and the authorization layer rejects calls missing the required session scope before allowing the handler. Persisted opt-in cannot bypass the independent environment gate.

Resilience and Maintainability Implications

  • observed — Consent enforcement consumes a published change in a separate scoped fiber. Tests exercise immediate update-to-record/flush sequences and queue invalidation, but they do not establish a production acknowledgement barrier across all scheduling and interruption states. This remains an evidence gap, not a verified post-opt-out disclosure.

Hardening Proposals

  • proposed — Define whether a successful opt-out response guarantees that collection and delivery are already disabled, and validate that contract using production persistence with competing flushes and interruption. If immediate completion is required, make enforcement acknowledgement explicit.
  • proposed — Document that rollback to a server predating persisted consent requires T3CODE_TELEMETRY_ENABLED=false to preserve an opted-out environment’s privacy state.

Explanation

Issue #4123 requires telemetry to stay disabled until the user gives explicit consent. AnalyticsService still defaults T3CODE_TELEMETRY_ENABLED to true, and ServerSettings defaults telemetryEnabled to true. The PR adds an in-app opt-out after telemetry is enabled, not an opt-in flow. The reviewed changes provide a settings toggle and limited telemetry documentation, but they do not establish an in-app notice and consent flow or the required collection disclosure. The requested schema, telemetry history, and advance-notice policy are also not implemented; these are documentation or policy items rather than coding requirements.

Resolution

Change the initial telemetry state to disabled for users without an explicit opt-in. Add an in-app notice and consent flow that records the user choice. Add the required collection, timing, and destination disclosure in the application or linked product documentation. Add automated tests for the default-disabled and explicit-consent behavior.

startup, read it through enabled, and update it from the settingsChanges stream
supplied by subscribePersistedChanges; discard queued events only when the

Reject invalid batch sizes and buffer limits. Check the background retry deadline after acquiring the flush lock.
Honor the persisted preference for recording and delivery while preserving the environment override. Replace the queue on opt-out and consume settings updates before secret-store I/O so unfinished records and in-flight failures cannot restore discarded events.
Add analytics controls to web, desktop, and mobile settings, including environment override and mixed-selection states. Share the preference across connected environments and document both opt-out methods.

Move the telemetry environment check into a service.

layerWsRpc reads AnalyticsService.TelemetryEnabledConfig directly. This config read is capability logic in a transport handler. The path instructions require handlers to only decode input, call one service method, and map errors.

Expose a method on AnalyticsService, for example isDisabledByEnvironment. Call that method here.

As per path instructions: "Server capabilities belong in the domain service that owns them; transport handlers should only decode, call one service method, and map typed errors."
