Privacy Policy

1. Introduction

LinTech ("we", "our", or "us") operates the SleepAlly mobile application. This Privacy Policy explains what data we collect, how we use it, and how we protect it when you use our app. SleepAlly is designed with privacy in mind, and core sleep data stays on your device.

2. Data We Collect

SleepAlly collects the following information. The data listed below is stored on your device unless otherwise stated:

• Personal information: Name, gender, age, weight, and height entered during onboarding (stored on-device only)
• Sleep session data: Start and end times and session duration (on-device only)
• Snore event data: Snore events and optional short audio clips saved for review (on-device only)
• Habit diary entries: Food logs, medication, mood, and exercise information (on-device only)
• Subscription status: Premium active or inactive status, verified through Apple StoreKit on-device. We do not store payment card details.

3. How We Use Your Data

We use your data to:

• Provide app features, including Fall Asleep, Motion/Voice control, sleep tracking, and analytics
• Help verify premium subscription access for unlimited Start Night sessions
• Support your sleep insights and app experience

We do not sell, rent, or share your on-device database with advertisers.

4. Data Storage & Security

• Primary storage uses Apple SwiftData on your device
• No mandatory cloud account is required for core sleep features
• Your device is protected by iOS security features, including Face ID or a passcode

5. Third-Party Services

• Apple In-App Purchase / StoreKit: Subscription billing and receipt validation are handled by Apple. See Apple's Privacy Policy at apple.com/legal/privacy.
• YouTube: If you use a YouTube URL for fall-asleep or alarm audio, Google's player and policies apply while streaming.

6. Subscriptions & Payments

SleepAlly offers optional auto-renewable subscriptions:

• Premium Yearly ($29.99/year) — includes a 7-day free trial for eligible new subscribers
• Premium Monthly ($4.99/month) — no free trial

Payment processing is handled entirely by Apple through your Apple ID. LinTech does not collect or store credit card numbers or bank details. Subscription status is checked on-device through StoreKit to unlock unlimited Start Night sessions after your free trial uses are exhausted.

After a free trial on Premium Yearly, billing continues at the listed price unless you cancel at least 24 hours before the renewal date. Manage or cancel subscriptions in Settings → Apple ID → Subscriptions on your device. Restore Purchases is available in the app for users who reinstall or switch devices.

7. Microphone Access

• The microphone is used on-device for Motion/Voice control while Fall Asleep is paused, and only when Resume with is set to Sound or Either
• Audio is analysed on your device to detect a sound that should resume playback
• This audio is not saved as clips, uploaded, or continuously recorded to the cloud

8. Children's Privacy

SleepAlly is not directed at children under 13. We do not knowingly collect data from children.

9. Your Rights

• You can delete your Habit Diary data from Profile > Stored Data
• Deleting the app removes locally stored data
• EU/EEA users: Rights under GDPR apply, including access, rectification, erasure, portability, and objection
• California users: Rights under CCPA apply

10. Changes to This Policy

We will update the effective date when this policy changes. Continued use of the app after changes constitutes acceptance of the updated policy.
