Privacy Policy
This Privacy Policy explains how FlowWatch ("we", "our", or "the App") collects, uses, and safeguards information when you use our mobile application and related services at flowwatchapp.com.
1. Information We Collect
We only collect information strictly necessary to provide water sensing and usage visualization:
- Account Information: When you sign in via Google or Apple, we collect your name, email address, and authentication identifier provided by the identity provider.
- Sensor & Telemetry Data: Physical water sensors transmit vibration patterns, flow start/stop timestamps, sensor hardware IDs, and calibration settings.
- Custom Labels: Names and location labels you assign to your sensors (e.g. "Kitchen Sink", "Irrigation").
- Sharing & Invitation Information: When you invite other users to view your sensors, we store the recipient's email address and invitation status.
2. Device Permissions & Bluetooth
- Bluetooth (BLE): The App uses Bluetooth exclusively to discover nearby water sensors during setup and calibrate vibration detection thresholds. We do not use Bluetooth to track your location.
3. How We Use Your Information
- To calculate and visualize estimated water usage columns, activity timestamps, and multi-sensor charts.
- To enable secure sensor sharing with viewers you explicitly invite.
- To maintain secure synchronization and cloud data storage.
4. Data Sharing & Third Parties
We do not sell, rent, or monetize your personal or water usage data. We do not serve third-party ads.
Data is processed through trusted infrastructure providers strictly for core functionality:
- Cloud Infrastructure Providers: Secure database storage, user authentication, and backend processing.
- Transactional Email Providers: Used exclusively to deliver invitation links to people you choose to invite to view your sensors.
5. Data Retention & Deletion
You have full control over your data:
- Revoke Sharing: You can revoke viewer access to your sensors at any time directly in the app.
- Remove Sensor: Removing a sensor archives its history and permanently detaches access for all viewers.
- Account Deletion: You may request complete deletion of your account and associated sensor records at any time by contacting our support team.
6. Security
All communication between the App, water sensors, and cloud services uses industry-standard TLS encryption. Single-use invitation tokens are cryptographically hashed using SHA-256 and expire automatically after 7 days.
