Privacy Policy for Light Njoy

Information We Collect

Light Njoy is designed with privacy as a core principle. Here's what we access:

Information We Do NOT Collect

• Personal identification information (name, email, phone)
• Photos or camera access
• Contacts or calendar data
• Location data
• Microphone or audio recordings

Information Stored Locally

• App preferences (selected mode, layout, colors, brightness)
• Premium status
• Custom Njoy Setups you create
• Rewarded ad watch history — stored securely in device Keychain

This local data is never transmitted to our servers.

AI Features and Privacy

Light Njoy includes AI-powered features (LumiAI and Imagined Scenes) that use Apple's on-device intelligence:

• All AI processing happens on your device — no data is sent to external servers
• Your text prompts for color generation are processed locally using Apple's Foundation Models
• Imagined Scenes uses Apple's ImagePlayground API, which runs entirely on-device
• We have no access to your prompts or generated content
• AI features require Apple Intelligence-compatible hardware (iPhone 15 Pro or later)

Njoy Setups Sharing

When you share a Njoy Setup file:

• The .njoy file contains only lighting configuration (colors, timing, mode settings)
• No personal data is embedded in shared files
• Sharing uses standard iOS share sheet — we don't operate file hosting servers
• Files you import are stored only in your local Documents folder

Purchases

When you purchase Pro features, the transaction is processed entirely by Apple. We receive:

• Confirmation that a purchase is active
• Purchase type (lifetime Pro)

We do not receive your name, Apple ID, payment method, or any personal details.

Advertising

The free version of Light Njoy displays rewarded video ads through Google AdMob. AdMob may collect:

• Device advertising identifier (IDFA) — only if you grant tracking permission
• General location (country/region level, derived from IP)
• Device information (model, OS version)
• Ad interaction data

Pro users see no ads, and no advertising data is collected for them.

You can limit ad tracking in your device's Settings > Privacy & Security > Tracking.

Third-Party Services

• Apple App Store: Processes purchases
• Google AdMob: Displays rewarded video ads (free users only)
• Apple Foundation Models: On-device AI for LumiAI (no data leaves device)
• Apple ImagePlayground: On-device image generation (no data leaves device)

We do not use analytics SDKs, crash reporting services, or social media integrations.

Haptic Feedback

Light Njoy uses Core Haptics for the Breath Sync feature. Haptic patterns are generated locally and do not involve any data collection.

Data Security

Local data is protected by iOS security features. Rewarded ad tracking uses the secure Keychain. We do not operate servers that store your data.

Data Deletion

Since we don't collect personal data on our servers, there is nothing to delete on our end. To remove all app data from your device:

• Uninstall the app to remove all local data
• Njoy Setup files in your Documents folder will be removed
• Keychain data (reward tracking) is removed when you uninstall

Children's Privacy

Light Njoy is not directed at children under 13. We do not knowingly collect information from children.

Changes to This Policy

We may update this policy from time to time. Any changes will be posted on this page with an updated date.
