Optional by design
Core tracking works without AI. AI features are optional and run on-device.
PRIVACY
Private by architecture—not by promise.
No PrepAI account is required. Your PrepAI records stay in the local app database, Apple Health access is permission-based, and optional AI inference runs on your device.
No PrepAI cloud profile
There is no account containing your fitness history.
Permission-based Health access
Connect only the Apple Health categories you choose.
Manual portable backups
Create a passphrase-protected backup and store it somewhere you control.
Local deletion
Delete your PrepAI records without submitting a request.
What leaves the device?
Every network path the app can take, and what travels on it.
| ACTIVITY | LEAVES DEVICE? | EXPLANATION |
|---|---|---|
| Core PrepAI logs | No | Stored in the local application database |
| On-device inference | No | Inference runs locally on supported devices |
| Apple Health access | No | PrepAI reads or writes only authorized categories |
| Manual backup | User choice | You choose where to save or share the JSON file |
| App download and update checks | Yes | Uses Apple and Expo delivery infrastructure |
| Model download (optional) | Yes | AI model is downloaded from the internet when enabled |
| Purchase and restore | Yes | Apple handles payment; RevenueCat verifies Pro without receiving health records |
| Optional diagnostics | User choice | Only a sanitized allowlist is sent after explicit consent |
Data PrepAI stores
Health and fitness records you enter, plus Apple Health data you authorize, are stored in the app database on your device. PrepAI does not require or create a server-side health profile.
Network activity
The app can contact Apple or Expo infrastructure for installation and update checks, a model host when you approve an optional on-device AI download, RevenueCat for purchase and restore, and the diagnostics endpoint only after you opt in. Your local health-history database is not included in those requests.
Apple Health
PrepAI requests Health access only after you choose to connect it. Authorized data is used for app features and is not used by PrepAI for advertising or sold. You can change Health permissions in iOS Settings.
Optional diagnostics
Diagnostics are off until you explicitly opt in. Allowed events use reviewed enums and coarse fields such as app/build version, OS major, device tier, public channel, feature surface, result/error, and duration bucket. Health values, goals, choices, prompts, photos, generated output, free text, routes, and identifiers are excluded. Revoking consent stops uploads and deletes the unsent queue.
Purchases
PrepAI Pro is one capability entitlement available through a monthly auto-renewing subscription or a one-time lifetime purchase. Payment is processed by Apple. RevenueCat processes an anonymous App User ID, purchase and transaction history, and limited service technical metadata for entitlement and receipt validation, restore, fraud prevention, and purchase analytics. It is not a PrepAI account, and RevenueCat receives no wellness data through PrepAI. Subscription management and restore use the same Apple account.
Exports, support, and deletion
Files leave the app only when you choose a share destination. If you email support, the email service processes what you send. Delete Data on This Device removes PrepAI records, setup choices, reminders, downloaded AI resources, diagnostics state, local workspaces, and app-generated copies from this installation. It does not delete Apple Health samples, copies saved outside PrepAI, RevenueCat purchase-verification records, cancel or refund an Apple purchase or subscription, or remove it from the Apple ID. Purchase-verification deletion is a separate privacy request.
Retention and security
Local records remain until you delete them or remove the app. PrepAI relies on the iOS app sandbox and device protections; no storage system can be guaranteed risk-free. Keep exported files only in destinations you trust.
Contact and changes
This policy is effective August 3, 2026. Material changes will be reflected here and in the app release. A verified privacy and support contact will be published before the public release.

THE FOUR PILLARS
Adaptive guidance without the noise.
Four commitments shape every screen in PrepAI — what it shows you, what it keeps, and how it talks to you about your own body.
Personal
Guidance reflects your goals, history, preferences, equipment, and current readiness.
Private
Sensitive context is processed on-device wherever possible, with transparent controls for anything that leaves it.
Practical
Every insight ends in a clear action you can take today.
Progressive
The system rewards consistency and adapts without shame, hype, or punishment.
GETTING STARTED
Start without signing up.
Three steps and no PrepAI account required.
01
Set your goals
Enter the body metrics, targets, activity level, and preferences you want PrepAI to use.
02
Connect Health or log manually
Grant only the categories you choose. Denied or partial access never blocks manual tracking.
03
Get an inspectable plan
Review readiness, evidence, movement, meal, and recovery actions generated on device.
PRINCIPLES
Built differently on purpose.
Useful without an account
Start tracking immediately after local onboarding.
Complete without AI
Core tracking works even if no AI model is installed.
AI without a remote profile
Local inference should not require uploading your full history.
Portable by default
You can export and restore your own records.
Permission-based integration
Apple Health categories remain under system permission control.
Ad-free Pro
The free iOS experience may show one consent-gated non-personalized banner. Pro is available monthly or as a one-time lifetime purchase.
