Privacy Policy
Last updated: February 9, 2026
BLIP (“the App”) is a health and wellness application that helps you understand your daily recovery, sleep quality, and overall health trends using data from Apple Health. Your privacy is important to us.
Information We Collect
Health Data (Apple HealthKit)
BLIP reads the following data from Apple Health with your explicit permission:
- Heart rate and resting heart rate
- Heart rate variability (HRV)
- Sleep analysis (duration, stages, efficiency)
- Respiratory rate
- Blood oxygen saturation (SpO2)
- Wrist temperature
BLIP is read-only. The App never writes data to Apple Health.
Data Processing
- All health data processing happens entirely on your device
- Raw health data is never transmitted to any server, third party, or external service
- BLIP computes Recovery, Sleep, and Strain scores locally and caches only the computed scores (not raw data) on your device using Apple's SwiftData framework
AI Coach (Optional Feature)
If you choose to use the AI Coach feature:
- You must provide your own Anthropic API key, which is stored securely in the iOS Keychain on your device
- Your typed messages and aggregated health summaries (computed scores and trends) are sent to Anthropic's API for personalized coaching
- Raw Apple Health data is never sent to Anthropic or any other external service — only computed percentages and trend summaries
- Anthropic's use of your messages is governed by Anthropic's Privacy Policy and their API Terms of Service
- You can delete your API key at any time from the App's settings
- Conversation history is stored only on your device and can be deleted at any time from the App's settings
Information We Do NOT Collect
BLIP does not:
- Collect, transmit, or store any personally identifiable information
- Use analytics, tracking, or advertising frameworks of any kind
- Share or sell any data to third parties
- Transmit raw health data off your device
- Use health data for advertising purposes
- Include any third-party SDKs (zero external dependencies)
BLIP does not “sell” or “share” your personal information as those terms are defined under applicable privacy laws, including the California Consumer Privacy Act (CCPA).
Data Disclosure
BLIP may disclose limited information in the following circumstances:
- AI Coach: If you use the AI Coach feature, your typed messages and computed health summaries (scores and trends) are sent to Anthropic for processing. Raw Apple Health data is never sent. Anthropic's handling of this data is governed by their Privacy Policy and API Terms of Service.
- Legal obligations: We may disclose information if required by law, regulation, or legal process.
- Business transfers: In the event of a merger, acquisition, or sale of assets, your on-device data remains on your device. Any transfer of the app or business would remain subject to the commitments made in this Privacy Policy.
Data Storage
- Computed scores (Recovery percentage, Sleep percentage, Strain score) are cached on-device using SwiftData
- Your API key (if provided for AI Coach) is stored in the iOS Keychain with hardware-backed encryption
- All cached data can be deleted at any time through the App's settings
- Uninstalling the App removes all stored data from your device
Data Retention
BLIP retains computed health scores on your device for as long as the App is installed. You can clear all cached scores at any time. Health data is always queried fresh from Apple Health and is never permanently stored by BLIP.
Your Rights
You have the following rights with respect to your personal information:
- Right to know and access: You have the right to confirm whether we are collecting your personal information and to access that information.

By using the AI Coach feature, you consent to this transfer. Please refer to Anthropic's Privacy Policy for details on their data handling practices.
