LifeOS is a personal productivity application built and operated by Ajay Merchia. This policy describes how the app handles your data.
LifeOS collects only what is necessary to provide its features:
Account information: Your name and email address via Google Sign-In (Firebase Authentication).
Food and nutrition data: Food entries you log, including names, calorie counts, macronutrients, serving sizes, barcodes, and meal types. Custom foods you create are also stored.
Water intake data: Water consumption logs including amounts and custom aliases you create.
Habit tracking data: Daily habit completions, streak data, and personal goals you configure (e.g., weight targets).
Images: If you upload food photos or nutrition label images for AI parsing, those images are transmitted to Google Gemini for processing. We do not permanently store uploaded images.
Email metadata: If you connect Gmail, we access email sender names, subject lines, and snippets for the purpose of AI-powered inbox triage. Full email bodies are not stored. Email classifications and action metadata are stored in Firestore.
Messaging identifiers: If you link Telegram, we store your Telegram chat ID and chat title to send you accountability reminders.
AI conversation data: Inputs and outputs from AI agent sessions are stored in Firestore to maintain conversation history.
Personal access tokens: If you create API tokens for programmatic access, token hashes and usage metadata (creation date, last used) are stored.
If you connect Notion, we store an OAuth access token that allows the app to read and write to your selected Notion databases (food log, habit tracker). We do not access any Notion content beyond the databases you explicitly choose. You can disconnect Notion at any time from the Settings page, which revokes the app's access token.
If you connect Gmail, the app requests read, modify, and compose access to your Gmail account. OAuth credentials are encrypted using Google Cloud KMS envelope encryption before storage. The app syncs email metadata (sender, subject, snippet) for AI classification. You can disconnect Gmail at any time, which deletes stored credentials.
Your data is used solely to provide LifeOS features, including:
We do not sell, share, or transfer your data to any third parties for advertising or marketing purposes. We do not use your data for analytics beyond basic Firebase usage metrics.
Firebase (Google): Used for authentication, data storage (Firestore), and hosting. Governed by Google's Privacy Policy.
Google Gemini: Used for AI food parsing (text and image), email classification, habit accountability messages, and conversational agent features. Text, images, and email metadata you provide are sent to the Gemini API. No identifying information is attached. Governed by Google's Gemini API Terms.
Notion: If connected, your food log and habit data is written to your own Notion workspace. Governed by Notion's Privacy Policy.
FatSecret: Food search queries are sent to the FatSecret API to retrieve nutritional data. No personal data is included in these requests.
Gmail (Google): If connected, email metadata is accessed via the Gmail API for inbox triage. Governed by Google's Privacy Policy. Use of Gmail data adheres to Google API Services User Data Policy, including the Limited Use requirements.
Telegram: If linked, accountability messages are sent via the Telegram Bot API. Governed by Telegram's Privacy Policy.
Google Cloud Platform: Used for secret management (Secret Manager) and encryption (Cloud KMS). Governed by Google Cloud's Privacy Notice.
Your data is retained in Firestore and/or connected third-party services until you delete it. Specifically:
Gmail OAuth credentials are encrypted using Google Cloud KMS envelope encryption before storage. Personal access tokens are stored as SHA-256 hashes. All data is transmitted over HTTPS. Firestore security rules restrict data access to authenticated users.
