BriefMe · Last updated: March 29, 2026 · Effective: March 29, 2026

1. About This Policy

This Privacy Policy describes how BriefMe ("the App", "we", "us", or "our") handles information when you use the BriefMe mobile application on Android or iOS. By using the App, you agree to the practices described in this policy.

If you do not agree with any part of this policy, please discontinue use of the App.

2. Information We Do Not Collect

We do not collect, store, or process any of the following:

Your name, email address, phone number, or any contact details
Account credentials of any kind (the App has no login or registration)
Your precise or approximate location
Your contacts, calendar, photos, or files
Your browsing history or behavior outside the App
Payment information (the App has no in-app purchases)

3. Information That Is Collected

3.1 Anonymous Usage Events

The App sends anonymous, non-identifiable events to Google Firestore (a cloud database operated by Google). These events contain no personal data and cannot be linked to you as an individual. They are used solely to understand aggregate usage patterns and detect abuse.

Examples of events logged:

A user reached the daily brief limit (no user identity, no device ID — just a timestamp and event type)
A brief rating was submitted (topic name, rating value, timestamp — no user identity)

3.2 Device Attestation via Firebase App Check

To protect the App's AI services from automated abuse, the App uses Firebase App Check, which uses hardware-level attestation (Google Play Integrity on Android; DeviceCheck on iOS). This process verifies that requests originate from a genuine, unmodified installation of the App on a real device. It does not identify you as a person and does not transmit any data that could be used to track you.

3.3 On-Device Data (never leaves your device)

The App stores the following data locally on your device using standard OS storage (SharedPreferences). This data is never transmitted to any server:

Today's brief count (a number, reset daily) — used to enforce the daily usage limit
A brief history cache (topics you previously looked up and their generated content) — used to serve repeat requests without calling the AI again

4. AI-Generated Content

Important disclaimer: The App uses Google's Gemini AI (via Firebase Vertex AI) to generate educational content. AI-generated content may contain errors, inaccuracies, outdated information, or unintentionally misleading statements. Content should not be relied upon as a substitute for professional, medical, legal, financial, or academic advice. We make no representation or warranty regarding the accuracy, completeness, or fitness for any purpose of AI-generated content.

Topics, facts, statistics, and quotes are generated automatically by an AI system. We do not manually review or verify individual responses. Use the content for general educational interest only.

5. Third-Party Services

The App uses the following third-party services, each governed by their own privacy policies:

Google Firebase (Firestore, App Check, Vertex AI) — firebase.google.com/support/privacy
Google Play Services (Android) — policies.google.com/privacy

We are not responsible for the privacy practices of these third-party services. We encourage you to review their policies.

6. Children's Privacy

The App is rated for general audiences (4+ on App Store, Everyone on Google Play). We do not knowingly collect personal information from children under the age of 13 (or the equivalent minimum age in the relevant jurisdiction). Since the App does not collect any personal information from any user, this applies equally to all age groups.

If you are a parent or guardian and believe your child has provided personal information to us, please contact us at the address below. We will take steps to delete such information.

7. Data Retention

Anonymous usage events stored in Firestore are retained for up to 12 months and then automatically deleted or anonymized. On-device data (brief history and daily count) remains on your device until you uninstall the App or clear its data through your device settings.

8. Data Security

All communication between the App and our backend services is encrypted in transit using industry-standard TLS. Anonymous usage events do not contain personal identifiers, limiting the potential impact of any security incident. However, no method of transmission or storage is 100% secure, and we cannot guarantee absolute security.

9. Your Rights (GDPR / CCPA)

Because the App does not collect personal data as defined under the General Data Protection Regulation (GDPR) or the California Consumer Privacy Act (CCPA), most of the rights granted by those laws — such as the right to access, correct, or delete personal data — do not apply in the traditional sense.

If you believe we hold personal data about you and wish to exercise any applicable rights, please contact us using the details in Section 11. We will respond within 30 days.

10. Limitation of Liability

The App and all content within it are provided "as is" and "as available" without warranties of any kind, either express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, accuracy, or non-infringement.

To the maximum extent permitted by applicable law, we shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits or revenues, whether incurred directly or indirectly, or any loss of data, goodwill, or other intangible losses arising from:

Your use or inability to use the App
Any inaccurate, incomplete, or misleading content generated by the AI
Decisions made in reliance on content produced by the App
Unauthorized access to or alteration of your data
Any other matter relating to the App

11. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. We encourage you to review this policy periodically. Continued use of the App after changes are posted constitutes your acceptance of the revised policy.
