This Privacy Policy describes how Navaratnam Manoranjan, operating as Lumina Dev Apps (a division of Direct Parcel Distributors Inc., based in Oshawa, Ontario, Canada), collects, uses, and safeguards information when you use our iOS and macOS applications. This policy applies to all applications published under the Lumina Dev Apps brand.
Applications Covered
This Privacy Policy applies to all current and future applications developed and published by Lumina Dev Apps, including but not limited to:
Information We Collect
Our applications are designed to minimize data collection. We may request access to the following only when required to provide core functionality, and always with your explicit permission:
- Contact Information — such as name, email, or phone number, when you reach out to us directly.
- Device Contacts — accessed only when you grant explicit permission for features that require it.
- Microphone & Speech Data — used locally for translation, pronunciation, or voice-input features.
- Camera Access — used for barcode scanning, document capture, or photo features.
- Email Data — only when using communication features that require email integration.
- Health-Related Inputs — entered manually by users of medical apps (HealthDeck, PharmDeck, NurseToolkit, DoctorToolkit) and stored locally on your device.
- Inventory & Business Data — entered by users of business apps (SwiftRegister, EasyInventory, ProInvoice) and stored locally or in your chosen cloud account.
All data access is permission-based and controlled by you through your device settings.
How We Use Your Information
Information collected is used solely to:
- Provide, maintain, and improve our application features.
- Respond to support requests and communications.
- Diagnose and resolve technical issues.
We do not use your data for advertising, profiling, or behavioral tracking.
AI & Third-Party Services
Some of our applications include AI-powered features (such as differential diagnosis in DoctorToolkit, grammar correction in AI Girl Tutor, resume generation in AI Resume Builder, and step-by-step math tutoring in MathSolverAI). When you use these features:
- The text or input you provide may be sent to Anthropic (the AI provider) to generate a response.
- For applications that accept photo input (such as MathSolverAI), the photo you select or capture is sent to Anthropic solely to identify the content of the image (for example, the math problem written on the page) and generate an educational response. Photos are not stored by Lumina Dev Apps and are used only for the duration of the request.
- No personally identifying information is sent unless you explicitly include it in your input.
- Anthropic's data handling is governed by their own privacy policy, available at anthropic.com/legal/privacy.
Data Sharing
We do not sell, trade, rent, or share your personal information with third parties for marketing or commercial purposes. Information may only be shared in the following limited circumstances:
- With service providers strictly necessary for app functionality (e.g., Apple's App Store, Anthropic's AI services).
- When required by law, court order, or to protect our legal rights.
Data Storage & Security
The vast majority of data created in our applications is stored locally on your device. Where cloud storage is offered (such as iCloud sync), it uses Apple's secure infrastructure and your existing Apple ID.
We implement reasonable technical and organizational security measures to protect information transmitted to our services. However, no method of electronic transmission or storage is 100% secure.
Children's Privacy
Our applications are not directed at children under 13, and we do not knowingly collect personal information from children. Apps marketed to younger audiences (such as KidLearn) operate entirely on-device with no data collection.
Your Rights & Choices
You have the right to:
- Manage permissions at any time through your device's Settings app.
- Delete locally stored data by removing the application or clearing it within app settings.
- Request information about any personal data we may hold by contacting us at the email below.
- Request deletion of any personal data we may hold.
Changes to This Policy
We may update this Privacy Policy from time to time. The latest version will always be available at luminadevapps.com/privacy-policy, with the "Last updated" date reflecting the most recent revision.
