3.3 Scanner and AI-related data

• KaLens processes label photos on-device for OCR (text extraction).

• KaLens asks for explicit in-app consent before third-party AI processing where required by the app flow.

• For support/feedback submissions, KaLens may include device info such as network type, screen size, display scale, low power mode, and a bucketed free-storage label.
• Permission states (for example, camera and notifications) and other operational metadata.

3.5 Information we do not collect for tracking ads

• KaLens currently does not use Apple ATT permission prompts.
• KaLens does not currently use cross-app or cross-website advertising tracking through ATT-based flows.

• Authenticate users and secure accounts.
• Operate subscriptions, entitlements, and paywalls.
• Respond to support requests and user feedback.
• Analyze usage and improve performance, accuracy, and reliability.

5. Legal Bases (EEA/UK)

Where GDPR/UK GDPR applies, we rely on one or more of these legal bases:

• Contract: to provide KaLens services you request.
• Legitimate interests: to improve, secure, and operate the app responsibly.
• Consent: where required (for example, certain permissions or optional processing).
• Legal obligation: where processing is required by law.

6. Sharing and Processors

We use service providers (processors/sub-processors) to run KaLens:

We may disclose information if required by law, court order, or to protect rights, safety, and security.

7. International Data Transfers

Because KaLens uses global service providers, information may be processed in countries other than your own. Where required, we use appropriate safeguards for international transfers.

8. Data Retention

• We generally retain personal data while your account is active.
• If you request deletion, we will remove personal data from our databases manually within up to 60 days, unless law allows an extension.
• To complete deletion, we may require request confirmation via support@kalens.app.
• We may keep data that is no longer personal (for example, anonymized analytics) and certain non-personal product-level information.
• We may retain limited data when legally required.

9. Your Privacy Choices and Rights

9.1 In-app and device controls

• You can manage camera and notification permissions in iOS Settings.
• You can manage AI processing permission through the app flow/settings behavior.
• You can manage subscriptions through Apple subscription settings.

9.2 Rights by region

Depending on your location, you may have rights such as access, correction, deletion, portability, objection, restriction, or appeal.

• EEA/UK: GDPR/UK GDPR rights, including complaint rights with a supervisory authority.
• US state laws (where applicable): rights to know, access, delete, and correct, and to non-discrimination for exercising rights.
• Other regions: rights provided by local law.

To exercise rights, email support@kalens.app. We complete requests within 60 days, unless law allows an extension.

10. Do Not Sell or Share

KaLens does not sell personal information for money. KaLens also does not share personal information for cross-context behavioral advertising as described by applicable US privacy laws, based on current app practices.

11. Children

KaLens is intended for a general audience and is not directed to children under 13. If you believe a child has provided personal data, contact support@kalens.app.

12. Security

We use administrative, technical, and organizational safeguards designed to protect personal information. No method of storage or transmission is fully secure, so absolute security cannot be guaranteed.
