Ready2Run is built to be private: your health data and your readiness verdicts are processed on your iPhone and are never sent to us. Here is exactly what the app uses.
The short version: Your HRV, heart-rate, and sleep data stay on your device. We can't see them, we don't store them on any server, and we never sell or share them. The only thing that leaves your phone is anonymous, aggregate app-usage and crash information that contains none of your health measurements.
1. Health & Fitness Data (Apple HealthKit)
With your permission, Ready2Run reads the following from Apple HealthKit, read-only: heart-rate variability (SDNN), resting heart rate, and sleep analysis (time asleep and wake time). This is used for one purpose only — to calculate the readiness verdict, factors, and trend chart you see in the app.
Every calculation runs entirely on your iPhone. The data is never transmitted to Ready2Run, to any server, or to any third party.
Ready2Run never writes to HealthKit and never modifies your health records. (iOS still requires a "write" usage description even for read-only apps.)
Your health data and verdicts are never used for advertising and are never sold.
On your device the data lives in Apple HealthKit (which you control) and in a small local cache and shared app container so the app, its widgets, and its Apple Watch complications can display your latest verdict. It syncs to your paired Apple Watch over Apple's encrypted device-to-device connection.
You can revoke access to any health data type at any time in iOS Settings → Privacy & Security → Health → Ready2Run. Deleting the app removes its local cache from your device.
2. Analytics & Diagnostics
To fix bugs and understand which features are used, Ready2Run collects a small amount of anonymous, aggregate information through Google Firebase (Analytics and Crashlytics):
Usage events — e.g. the app was opened, onboarding was completed, health access was requested, a readiness verdict was shown, a background refresh ran, a reminder was switched on or off, and error codes.
How many days of data the app has gathered while it is still calibrating, and whether your baseline is calibrating, provisional, or established.
Crash reports and the basic device information that accompanies them (e.g. OS version, device model, approximate region).
A Firebase installation identifier used to group these events.
This analytics stream never includes your actual HRV, heart-rate, or sleep values — and never the verdict itself. We record only that a verdict was shown, never whether it said train, easy, or rest: a readiness verdict is inferred health information, and it stays on your device like the measurements behind it. Nothing here is linked to your name or identity (Ready2Run has no accounts), and none of it is used to track you across other apps or websites — no advertising identifier (IDFA) is used.
No advertising identifier and no cross-app or cross-site tracking.
No transmission of your health measurements — or of the verdicts computed from them — off your device, ever.
We do not sell, rent, or share your personal data.
4. Data Retention
Your health data stays in Apple HealthKit under your control. Ready2Run's on-device cache exists only while the app is installed and is removed when you delete it. Anonymous analytics and crash data are retained by Google according to their policies.
5. Children's Privacy
Ready2Run is not directed to children under 13, and we do not knowingly collect personal information from them.
6. Your Rights & Choices
Grant or revoke HealthKit access at any time in iOS Settings. Delete the app to remove its local cache. Because analytics is anonymous and not tied to an identity, there is no personal profile of you for us to hold, access, or delete.
7. Security
Calculations run on your device, protected by iOS's built-in data-protection encryption. Because your health data never reaches a server we operate, there is no central store of it to be breached.
8. Changes to This Policy
We may update this policy as the app evolves. Material changes will appear here with a new "Last updated" date.
Ready2Run provides general fitness and wellness information to help you plan training. It is not a medical device and does not provide medical advice. It does not diagnose, treat, cure, or prevent any disease or condition, and its readiness verdict is an estimate, not a clinical measurement. Always listen to your body, and consult a qualified healthcare professional before starting, changing, or stopping any exercise program, or if you have any concern about your health. Never disregard professional medical advice because of something in this app.
