A comprehensive engineering guide to implementing privacy in mobile applications through a five-stage lifecycle: collect, store, process, send, and delete. Covers threat modeling, data classification under GDPR and similar regulations, lawful grounds for processing, and practical implementation patterns. Includes specific guidance on secure storage (Keychain/Keystore vs encrypted databases), telemetry redaction, network boundaries with certificate pinning, on-device ML privacy, and SDK intake processes. Provides copy-paste ready checklists for design docs, release reviews, deletion orchestrators, and common privacy code smells to watch for during development.
