Your week balanced strong training with better recovery, but shorter sleep looks like the main limiter for tennis progress
You kept training quality high this week, especially through two paired strength-plus-running days and one solid tennis session. At the same time, your resting heart rate (RHR) improved from 57 to 55 and your heart rate variability (HRV) improved from 49 to 51, while daily movement was much higher than last week. What this suggests is that your overall load is still sitting in a workable place, but sleep fell from 7.6 to 6.7 hours and may be keeping you from getting even more out of the work. The most useful thing to try this week is protecting sleep on the nights before and after tennis or double-session days, since those are your highest-demand windows.
Recovery & Rest
Your data consistently shows a strong activity base this week, with steps rising from 7269 to 10565 and daily distance rising from 5.32 to 7.47 km, even though total workouts dropped from 7 to 6. That matters because you did not need extra sessions to keep the week active. The two back-to-back paired sessions on Monday and Tuesday gave you a lot of quality in a compact format, and your recovery markers still held up well overall.

Privacy Policy

Last updated: March 31, 2026

Overview

VitalBrief is a wellness app that reads Apple Health data on your device and generates AI-powered reports. Your privacy is not a feature, it's the foundation of how the app is built.

Data We Collect

We do not collect personal information. VitalBrief has no user accounts, no login, no email collection, and no registration of any kind. We do not receive your name, email, or Apple ID.

Health Data

VitalBrief accesses the following health data types from Apple HealthKit, with your explicit permission. The app works with any device that syncs to Apple Health, including Apple Watch, Garmin, Oura Ring, Whoop, Fitbit, and Withings:

  • Activity: Steps, distance walked/run, active energy burned, exercise minutes, stand hours
  • Heart: Resting heart rate, heart rate variability (HRV), heart rate recovery
  • Body: Body mass, respiratory rate, blood oxygen saturation (SpO2), walking steadiness, wrist temperature
  • Sleep: Sleep duration and sleep stage analysis
  • Fitness: VO2 Max, workout sessions (type, duration, distance, heart rate zones, cadence)
  • Other: Daylight exposure time

This data is used exclusively to generate your wellness reports. It is never used for advertising, data mining, or any purpose other than the app's core functionality.

How Your Data Is Stored

All data, including your profile, preferences, and generated reports, is stored locally on your device. VitalBrief does not maintain any server-side database or cloud backup of your data. Your health information lives on your device, protected by Apple's built-in security.

AI Report Generation

When you generate a report, anonymized health metrics are processed by an external AI service to create your wellness insights. Here's what you should know:

  • The data contains no personally identifiable information, no name, no email, no device ID, no account ID
  • Only the health metrics needed for the report are included (e.g., step counts, heart rate averages, workout summaries)
  • Basic profile context is included (age range, height, biological sex, sport preferences) to personalize insights. If you've added optional notes in the "About You" field, that text is also included. No other personal information is sent.
  • Data is transmitted over encrypted connections (HTTPS/TLS)
  • AI providers operate under agreements that prohibit using your data for training

You provide explicit consent before any health data is processed by the AI service for the first time.

Notifications

VitalBrief uses local notifications only. These are scheduled on your device to let you know when a new report is available. No remote push notification server is involved. No notification data leaves your device.

Subscriptions

Subscriptions are managed entirely through Apple's App Store and StoreKit framework. We do not process, store, or have access to any payment information. All billing is handled by Apple.

Third-Party Services

When generating reports, your data is processed by two external services: a secure proxy (Cloudflare) that routes your request, and an AI service that generates your report. Neither service receives your name, email, or any personal identifier. We do not use analytics SDKs, advertising networks, crash reporting tools, or any other third-party services that collect user data.

Children's Privacy

VitalBrief is not designed for or directed at children under 13. We do not knowingly collect information from children.

Data Deletion

Since all data is stored on your device, you have complete control. You can delete all app data at any time by deleting the app from your device. VitalBrief does not maintain any server-side copy of your data.

Changes to This Policy

If we update this privacy policy, we will post the revised version at this URL with an updated date. Significant changes will be communicated through the app.
