Privacy Policy

Last updated: February 22, 2026

This Privacy Policy explains how Sabrina Miao, operating as Flow Watt ("we", "us", or "our") collects, uses, discloses, and protects information when you use the Flow Watt mobile application, this website, and related services (together, the "Service"). By using the Service, you agree to the collection and use of information in accordance with this policy.

Scope: This policy applies to personal and non-personal information collected through the Flow Watt app, this website, our documentation, support channels, and any in-app analytics or third-party integrations.

1. Information We Collect

Information you provide directly:

  • Account details you optionally create (name, email address).
  • Settings and preferences stored in the app (for example: units, notification preferences).
  • Support communications and feedback (messages you send via email or in-app contact forms).

1. Information We Collect

Device and usage information:

  • Device model, operating system version, app version, language and locale settings.
  • Crash reports, performance logs, and other diagnostic data that help us improve the app.
  • Usage analytics (screens visited, features used, timestamps) — collected in aggregate or pseudonymized form where possible.

1. Information We Collect

Website information (this website):

  • This website uses Firebase Hosting and Firebase Analytics (provided by Google LLC). Firebase Analytics may collect device identifiers, approximate location derived from IP address, pages visited, and session data. Firebase may use cookies and similar tracking technologies to operate and improve the Service. See Google's Privacy Policy and the Firebase Privacy and Security page for details.
  • Cookies and similar technologies: We use technically necessary cookies (required for the website to function) and analytics cookies set by Firebase. Where required by law, analytics cookies are only placed with your consent. You can manage or disable cookies in your browser settings; disabling cookies may affect website functionality.

1. Information We Collect

Sensor or system data (only if applicable and with your consent):

  • If Flow Watt integrates with device sensors or external services (for example, power/energy monitoring hardware or cloud accounts), we may collect relevant telemetry. We only collect this data when you explicitly connect the service and grant permission.

2. How We Use Information

  • Provide and maintain the Service.
  • Improve and personalise the user experience, including troubleshooting and analytics.
  • Send relevant notifications and updates if you opt in.
  • Respond to support requests and communicate about account or service changes.
  • Detect, investigate, and prevent fraudulent or other illegal activities and security incidents.

3. Automated Decision-Making

We do not make decisions about you solely by automated means that produce legal or similarly significant effects. Analytics data may be used to generate personalised tips within the app, but no legally significant automated decisions are made.

4. Legal Basis (for users in the EEA/UK)

Where applicable under the GDPR or UK GDPR, we process personal data on the following bases:

  • Consent — for analytics cookies and optional marketing communications. You may withdraw consent at any time by emailing flowwatt-feedback@gmail.com or by adjusting your browser cookie settings. Withdrawal does not affect the lawfulness of prior processing.
  • Performance of a contract — to provide the Service you have requested.
  • Legitimate interests — to improve the Service, detect abuse, and maintain security, where these interests are not overridden by your rights.

5. Sharing and Disclosure

We do not sell your personal data. We may share information in the following limited circumstances:

Service providers and data processors:

We use the following third-party services that may process data on our behalf:

  • Google Firebase (Google LLC) — app hosting, authentication, analytics, crash reporting, and cloud functions. Privacy info.

5. Sharing and Disclosure

These providers are contractually bound to process data only for the purposes we specify and in accordance with applicable law.

Third-party integrations:

When you connect a third-party service (for example, a cloud energy provider or hardware partner), data necessary for that integration will be shared with the third party only with your explicit authorisation.

Legal requirements:

We may disclose information to comply with legal obligations, respond to lawful requests from public authorities, or protect our rights, property, safety, or users.

Business transfers:

If Flow Watt is involved in a merger, acquisition, reorganisation, or sale of assets, your information may be transferred as part of that transaction. We will require the acquirer to honour this Privacy Policy.

6. Data Retention

We retain personal data only as long as necessary to provide the Service and fulfil the purposes described in this policy, or as required by law. Aggregate or anonymised data may be retained indefinitely for analytics and product improvement purposes.

7. Security

We implement reasonable administrative, technical, and physical safeguards to protect information against unauthorised access, disclosure, alteration, or destruction. However, no method of transmission or storage is 100% secure — if you believe your account has been compromised, contact us immediately (see Contact section below).

8. Your Rights

10. International Transfers

Data collected by Flow Watt may be processed and stored in countries other than your country of residence, including the United States (where Google LLC operates Firebase infrastructure). When we transfer personal data across borders, we take steps to ensure appropriate safeguards are in place in accordance with applicable law (for example, Standard Contractual Clauses for transfers from the EEA).

11. Third-Party Services and Links

The Service may contain links to third-party websites, services, or SDKs. We are not responsible for the privacy practices or content of those third parties. Please review their privacy policies before providing information.

We may update this Privacy Policy to reflect changes in our practices or legal requirements. When we make material changes, we will provide prominent notice (for example, an in-app notification or an update to the effective date at the top of this page). Continued use of the Service after the effective date constitutes acceptance of the updated policy.
