How Aldian Apps Protects Your Data & Privacy
Clear Data Sovereignty • User-Owned Storage vs. Secure Multi-Tenant Backend
User-Owned Cloud Storage (BYOD)
Personal productivity apps (Journal, Transcribe Copilot, Successful Day, Hanzi Scribe) sync directly to designated folders in your personal Google Drive. No intermediary database stores your files.
Secure Cloud Backend (Firestore)
Multi-user and business apps (Tetangga, KlinikOS, Toko Grosir) store data in authenticated Google Cloud Firestore collections with strict tenant isolation, role-based rules, and at-rest encryption.
Direct BYOK AI & Local Crypto
When using AI, your browser communicates directly with AI providers using your own keys. Sensitive configurations are protected with client-side AES-GCM 256-bit encryption.
