Privacy Policy

Last updated: June 25, 2026

BeInLuck ("BeInLuck", "we", "us") is a daily wellness check-in that lets you read signals like heart rate and breathing from your face using your phone's camera — no wearable required. This policy explains, in plain language, what we do and don't do with your information.

Your face never leaves your device. The camera feed is processed entirely on your own device, inside your browser. Raw camera frames and video are never uploaded, transmitted, or stored on our servers — ever. We only keep the resulting numbers.

1. What we collect

On your device only (never sent to us): the live camera image used to compute your readings. It stays in your browser's memory for the moment of measurement and is then discarded.
Stored in your account: the numeric results of a check-in — heart rate (BPM), breathing rate, an eye-fatigue score, signal quality, and the date/time.
Account basics (via Google Sign-In): your name, email address, and profile picture, used to sign you in and sync your check-in history across your devices.

2. How we use it

To show you your check-in results, history, and trends over time.
To sign you in and keep your data tied to your account across devices.
To keep the service working, secure, and reliable.

We do not use your data for advertising, and we do not sell your personal information.

3. Google Sign-In

We use Google Sign-In only to authenticate you. We request basic profile and email information (name, email, profile picture). We do not request access to any other Google data. BeInLuck's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

4. Where your data is stored

Your numeric results and account basics are stored using Google Firebase (Firestore and Firebase Authentication), operated by Google. Data is encrypted in transit and at rest by Google's infrastructure. Google acts as our data processor.

5. Retention & deletion

We keep your check-in history until you delete it or delete your account. You can ask us to delete your account and all associated data at any time by emailing hello@beinluck.app. We will remove your data within a reasonable period.

6. Your rights

Depending on where you live, you may have the right to access, correct, export, or delete your personal data, and to withdraw consent. To exercise any of these, contact us at hello@beinluck.app.

7. Children

BeInLuck is not directed to children under 13 (or the minimum age in your country), and we do not knowingly collect their personal information.

8. Security

We rely on Google's secure infrastructure and follow good practices to protect your information. No method of storage or transmission is 100% secure, but because your camera data never leaves your device, the most sensitive part of BeInLuck never reaches a server at all.

9. Changes to this policy

We may update this policy from time to time. We'll post the new version here and update the date above. Significant changes will be communicated within the app.
