Privacy Policy

This Privacy Policy describes how LyuPro (“we”, “us”, or “our”) collects, uses, and protects information when you use our mobile applications. This policy applies to all apps published by LyuPro on the Apple App Store and Google Play Store.

Each of our apps may also include an in-app privacy policy with additional details specific to that app’s functionality.

1. Information We Collect

Our apps are designed with privacy in mind. We minimize data collection and prefer on-device processing whenever possible.

Information you provide

• Data you enter into the app (notes, records, preferences, settings)
• Support requests and feedback you send us via email

Automatically collected information

• Device information: device model, operating system version, app version
• Usage data: app launch frequency, feature usage patterns (anonymized)
• Purchase data: subscription status and transaction identifiers (processed by the platform’s payment system)

Information we do NOT collect

• We do not collect your name, email address, or phone number (unless you contact support)
• We do not collect precise location data
• We do not create advertising profiles
• We do not sell any personal data

2. How We Use Information

• App functionality: to provide and improve the features you use
• Subscriptions: to manage your premium access and restore purchases
• AI features: some apps send user-provided data to a third-party AI service for processing (e.g., image recognition, text generation). This data is used solely for providing the requested feature and is not stored by the AI provider for training purposes
• Support: to respond to your questions and resolve issues
• Improvements: to understand how our apps are used and make them better

3. Third-Party Services

Our apps may use the following third-party services:

Service	Purpose	Data shared
RevenueCat	Subscription management	Anonymous user ID, purchase receipts
AI Provider (varies by app)	AI-powered features	User-provided content for processing only
Apple / Google	App distribution, payments	As per platform policies

Each third-party service operates under its own privacy policy. We encourage you to review their policies.

4. Data Storage and Security

• On-device storage: the majority of your data is stored locally on your device and is not transmitted to our servers
• No account required: our apps do not require registration or login
• Encryption: data transmitted to third-party services uses industry-standard TLS encryption
• No centralized database: we do not maintain a database of user data

5. Children’s Privacy

Our apps are not directed at children under the age of 13 (or the applicable age in your jurisdiction). We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will delete it.

6. Your Rights

You have the right to:

• Access your data: all your data is stored on your device and accessible to you at any time
• Export your data: most of our apps include a data export feature in Settings
• Delete your data: use the “Delete All Data” option in the app’s Settings, or simply uninstall the app
• Opt out of AI processing: if the app has AI features, you can choose not to use them

7. Data Deletion

To delete all data associated with an app:

1. Open the app and go to Settings
2. Tap Delete All Data
3. Confirm the deletion

Alternatively, uninstalling the app removes all locally stored data. If you need assistance, contact us at the email below.

8. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be reflected by updating the “Last updated” date at the top of this page. Continued use of our apps after changes constitutes acceptance of the updated policy.
