Transparent Data & Cloud Storage Architecture:
Guest Mode: 100% on-device execution with zero cloud sync—all notes, calculations, and tool data stay strictly on your device.
Gmail Sign-in Mode: Only 8 personal productivity tools (Notepad, Expense Tracker, Pro Counter, Water Reminder, To-Do List, Event Countdown, History activity logs, and Tool Yaar AI chat) sync securely to Google Cloud Firestore with AES-256 encryption.
Secure Space (Vault): 100% local encrypted storage—nothing from Secure Space is ever uploaded or synced to Firestore, even when logged in.
Zero Custom File Servers: Tool Yaar operates zero custom file-storage servers. Your PDF documents, photos, and files are processed strictly on your phone—only an activity entry name (e.g. “Image compressed”) is recorded in History.
Tool Yaar AI Attachments: Attached photos or PDFs are never stored on Tool Yaar servers or database; they are forwarded directly to upstream AI model provider servers (via OpenRouter) solely for inference.
