Effective Date: 2025/10/04
Welcome to Lose Double Chin Exercise, operated by Karasou Studios Inc. (“we,” “our,” or “us”).
Your privacy is very important to us. This Privacy Policy explains how our app handles your information. The most important point is simple: we do not collect, store, or share any type of personal data from users. Our app is designed to function without requiring any user data, which means you can use it with complete peace of mind.
By using our app, you are agreeing to the practices described in this Privacy Policy.
1. Information We Collect
We do not require users to create an account or register to use the app. Any information you provide, such as gender, age, daily workout time preference, or your main goal, is collected only to personalize your experience and is stored locally on your device. We do not upload this data to servers or share it with third parties.
2. How We Use Your Information
The data you provide is used solely within the app for:
- Generating personalized workout plans.
- Customizing the app experience.
- Improving app functionality and performance.
We do not:
- Collect personal identifiers like names, emails, or phone numbers.
- Sell or share your data with advertisers or third parties.
- Use your data for marketing purposes without consent.
3. Data Storage & Security
- Your data stays on your device only.
- We do not maintain our own servers to store your personal information.
4. Third-Party SDKs
Our app uses Firebase to help us understand app performance, fix technical issues, and improve the overall user experience. Firebase may collect anonymized usage and performance data as described in its own policies. We do not share or send any personally identifiable information to Firebase.
You can learn more about Firebase’s data practices here:
5. Permissions We Request
Our app may request limited permissions from your device to function correctly. These include:
- VIBRATE Permission
Used to provide haptic feedback during workouts and app interactions.
We do not collect or store any vibration-related data. - INTERNET Permission
Used only to load third-party SDKs like Firebase Analytics and Crashlytics.
No personal data is uploaded or transmitted to our own servers. - POST_NOTIFICATIONS Permission
Used to send workout reminders or motivational notifications to help you stay on track.
You can manage or disable notifications through your device settings at any time.
We do not request permissions to access sensitive information such as contacts, camera, microphone, or location.
6. Children’s Privacy
Our app is designed for general users and is not specifically targeted at children under 13.
- We do not knowingly collect personal data from children.
- The only data asked (such as age and goals) is for customizing workouts and remains stored locally on the device.
- If you are a parent or guardian and believe your child has provided personal information to us, please contact us at support@karasou.studio. We will promptly review and delete any such information.
7. Data Sharing & Disclosure
We do not sell, rent, or trade your personal data.
We only share limited, non-personal, anonymized information with third-party SDKs for app analytics and performance monitoring, such as:
- Firebase Analytics – Helps us understand app usage trends.
- Firebase Crashlytics – Helps us detect and fix app crashes.
These SDKs collect data under their own privacy policies. No personal identifiers like names or emails are shared.
8. User Rights
You have full control over your data because it is stored locally on your device. This means:
- Access: You can view the data you entered in the app anytime.
- Deletion: You can delete the app at any time, which will erase all data stored on your device.
Since we do not store your data on our servers, we cannot recover or access it once you delete the app.
9. Legal Compliance
We comply with applicable data protection laws, including:
- GDPR (General Data Protection Regulation)
- CCPA (California Consumer Privacy Act)
Although our app is not designed to collect personally identifiable data, we still ensure transparency and user control in line with these regulations.
10. Data Security
We take your privacy and data security seriously. Although we do not collect or store personal information on our servers, we implement the following safeguards:
- All user data remains stored locally on your device.
- No unencrypted transmission of personal data occurs from your device to our servers.
- Any communication with third-party SDKs (like Firebase) is handled securely over HTTPS.
Because we do not maintain your personal data on our servers, any loss or breach of your local device security is outside our control. We encourage you to secure your device with a password or biometric lock to protect your data.
11. Third-Party Links & Services
Our app may include links to third-party websites or services. These are provided for your convenience (e.g., support pages or privacy policy links for SDKs).
Please note:
- We are not responsible for the privacy practices or content of third-party websites.
- When you click on a third-party link, you are subject to their privacy policies and terms.
We recommend reviewing the privacy policies of any third-party services you interact with.

Currently, our app does not include third-party ads.
If we introduce advertising in the future:

If we make significant changes:
- We will notify you in the app or via a prominent notice before changes take effect.
