Privacy policy for the echolens companion app – Apple App Store

Introduction

This privacy policy explains how echolens, owned and operated by Lunitech, handles personal data collected from users of the echolens companion app on Apple devices. The policy complies with Apple’s App Store requirements and the Privacy Nutrition Labels in App Store Connect. If you use our services through other platforms (such as Google Play), please refer to the policy specific to that platform.

Data types we collect

To align with Apple’s data categories, we collect the following information:

• Email address (contact information): You provide your email address when registering for an account. We use it to authenticate your account, send service notifications (such as password resets), and respond to support inquiries. This data is linked to your account but is not used for tracking or advertising.
  
  
• Location data (precise and coarse): With your permission, the app accesses your device’s location to enable features like geotagging and to synchronize settings between your device and the echolens camera hardware. Location data is associated with your account only for these features. We do not share location information with third parties or use it for targeted advertising.
  
  
• Optional usage data: We may collect anonymized technical data such as crash reports, device type, and operating system version. These data help us diagnose issues and improve performance. They are not linked to individual users and are not used for advertising or tracking.
  
  

We do not collect other data types such as financial information, health data, contacts, photos, audio recordings, or advertising identifiers.

How we use data

• App functionality: Your email address and password are used to create, authenticate, and manage your account. Location data supports geotagging and adjusts camera settings based on your position. If you decline location access, these features may be limited but the app will otherwise continue to function.
  
  
• Product personalization: We may customize certain settings or features based on your device and location to improve your experience. For example, we may automatically adjust time zone settings or suggest camera configurations appropriate to your environment.
  
  
• Performance and analytics: Aggregated and anonymized crash logs or usage information help us monitor system performance, fix bugs, and enhance security. This information does not identify you.
  
  
• Legal compliance and security: We use information to detect and prevent fraudulent activity, protect the security of our services, and comply with applicable laws.
  
  

Data sharing and third‑party partners

We do not share your personal data (email or location) with advertisers or data brokers. We only share data under limited circumstances:

• Service providers: We rely on trusted vendors for hosting, support, and analytics. These providers process data solely on our behalf, under confidentiality obligations, and do not use it for their own purposes.
  
  
• Legal requirements: We may disclose information if required to do so by law or to protect our rights and the safety of our users.
  
  

Because we do not integrate advertising SDKs or allow third parties to track users, our app does not engage in tracking as defined by Apple’s privacy guidelines.

Your rights and choices

• Review and update: You can view and modify your email address, password, and preferences in the app’s settings.
  
  
• Location control: You have full control over whether the app accesses your location. Use your device settings to grant or revoke permission at any time.
  
  
• Account deletion: You can request deletion of your account and associated data through the app’s Delete Account feature, via our website, or by emailing support@echolenscamera.com. We will remove your data from our active systems unless retention is necessary for security, fraud prevention, or legal compliance. Where retention is required, we will anonymize or de‑identify the information.
  
  

Data retention

We store personal data while your account is active and as long as needed to provide the app’s features. Once you request deletion or your account becomes inactive, we will delete or anonymize your personal data unless the law requires us to retain it. Diagnostic logs used for performance monitoring are kept only as long as necessary to analyze and resolve issues.

Data security

We protect your information using technical and organizational safeguards, including hashed passwords, secure transmission via HTTPS, access controls, and periodic security reviews. Although no system can guarantee absolute security, we take reasonable steps to secure your data and encourage you to maintain the confidentiality of your login credentials.

Keeping App Store Connect information accurate

We will keep our privacy disclosures in App Store Connect accurate and up to date. If our data collection or use practices change, we will promptly update our privacy responses and notify you through the app or by email.

Changes to this policy

We may update this policy to reflect changes in our practices or to comply with Apple’s requirements. We will inform you of significant updates through the app or via email. Continued use of the app after such updates indicates your acceptance of the revised policy.
