1. Introduction
VoiceBeam GmbH ("we", "us", "our") operates the Two Hearts mobile application and the website twoheartsapp.com (collectively, the "Service"). This Privacy Policy explains what personal data we collect, how we use it, and your rights regarding that data.
We are committed to protecting your privacy. Two Hearts is designed to collect only the minimum amount of data necessary to provide the Service.
2. Data We Collect
When you use Two Hearts, we collect and store only the following data:

We do not collect your real name, email address (beyond what Apple provides through Sign in with Apple), phone number, location data, device identifiers for advertising, or any other personal information.
3. How We Use Your Data
Your data is used exclusively to provide the Two Hearts service:

- To enable sending and receiving heartbeat notifications
- To display your profile to other users who search for you by username
We do not use your data for advertising, profiling, analytics, or any purpose other than providing the core features of the app.
4. Heart Rate Data Retention
Heart rate data is automatically deleted after 24 hours. We do not retain historical heart rate data beyond this period. Once deleted, heart rate data cannot be recovered.
5. Data Storage and Security
Your data is stored on Firebase (Google Cloud Platform) servers located in the United States. All data is transmitted over encrypted connections using HTTPS/TLS. We follow industry-standard security practices to protect your data from unauthorized access.
6. Third-Party Services
Two Hearts uses the following third-party services:
- Firebase (Google) — for authentication, database storage, and cloud functions. Firebase processes data in accordance with Google's privacy policy.
- Apple HealthKit — for reading heart rate data from your device. Heart rate data is read locally and transmitted to our servers only with your explicit permission. We do not send health data to Apple.
- Sign in with Apple — for account authentication. Apple provides us with a unique identifier and, optionally, your email address (which may be a relay address).
- Vercel — for hosting the twoheartsapp.com website.
We do not share your personal data with any other third parties. We do not sell your data. We do not use advertising networks or tracking services within the app.
