downloadData(data: any) introduces the only explicit any in src/ and mixes UI concerns (Alert.alert) into a service module, which makes it harder to test and reuse. Consider (1) introducing a typed export result (e.g., { url: string; timestamp: string }) and (2) moving the alert/UI feedback into the screen layer while keeping the service purely side-effect/API focused.

This new service introduces significant user-facing behavior (export/deletion/consent) but has no Jest coverage, while other services (e.g. walletService) are tested. Adding unit tests for the success/error paths (including request failures) will help prevent regressions as the placeholder implementations are replaced with real API calls.

Consent toggles currently only update local Zustand state via setConsent, but never call gdprService.updateConsent(). That means consent changes are not sent to the backend / audit trail as described in the PR, and will be lost to the server-side view of consent. Please persist these changes by invoking updateConsent (with error handling/rollback) when toggles change.

The deletion confirmation copy says the action will "anonymize your data", but the code calls gdprService.requestDeletion(true) (i.e., permanent deletion). This is a behavioral mismatch for a destructive flow. Align the parameter and UI copy so the user is clearly requesting either anonymization/soft-delete or an irreversible hard delete.

updateConsent() accepts Partial<UserConsent>, but UserConsent includes fields like timestamp and dataProcessing; spreading a partial can produce incomplete records (e.g., missing required booleans) and the returned type no longer matches UserConsent. Consider defining an explicit input type (e.g. ConsentPreferences) and validating/normalizing missing fields before storing/logging to ensure a consistent audit trail schema.

exportUserData() currently constructs and returns hard-coded sample data (including an email address and subscription/billing records). Shipping this as-is risks leaking placeholder/incorrect PII and doesn’t actually export the requesting user’s data. Please replace the mocked payload with real queries (and keep the service returning structured data rather than a pre-stringified JSON blob so the API layer can choose the correct response headers/format).

API_BASE is hard-coded to https://api.subtrackr.example.com/gdpr, and exportData() returns a simulated URL containing a fixed export-user-123.json. This makes the feature non-functional outside a demo and risks shipping placeholder endpoints/identifiers. Please wire this to the app’s real API base/config + authenticated user context (or make the function explicitly unimplemented until the backend exists).

This screen hard-codes colors (e.g. #F8F9FA, #007AFF) and leaves Switch un-themed, while other screens use the shared design tokens (colors, spacing, typography) and set trackColor/thumbColor (see SettingsScreen.tsx and SubscriptionDetailScreen.tsx). Using the shared constants here will keep theming consistent (including dark mode) and reduce future style drift.

The contact address uses the placeholder domain privacy@subtrackr.example.com, while the app links use @subtrackr.app (e.g. support@subtrackr.app). Please align this to the real privacy contact email/domain so users aren’t directed to a non-functional address.

Frontend consent types (analytics, marketing, notifications) don’t align with the backend consent shape introduced in backend/services/gdpr.ts (analytics, notifications, dataProcessing, timestamp). Before wiring API calls, please standardize the consent schema across frontend/back end (field names + meaning), otherwise updateConsent calls will be ambiguous or silently drop fields.
