Privacy Policy — WeighPredictor

Last updated: July 15, 2026

The short version

WeighPredictor collects no data. Nothing ever leaves your iPhone.

Health data

• With your permission, the app reads your body-weight samples from Apple Health to display statistics, charts and predictions.
• If you enable the optional sync setting, weigh-ins you add or correct inside the app are written to Apple Health on your device.
• All processing happens locally on your iPhone. Your health data is never transmitted, uploaded, sold or shared with anyone — including the developer.
• Health data is never used for advertising or marketing, as required by Apple's HealthKit guidelines.

What the app stores

• Your profile (name, sex, height, birth year, anchors) is stored on your device only.
• Manual records and edits are stored in a local file on your device only.
• JSON exports are created only when you tap Export, and go only where you choose to share them.

What the app does NOT do

• No accounts, no sign-in.
• No analytics, no tracking, no ads, no third-party SDKs.
• No servers: the app makes no network requests with your data.

Purchases

The optional one-time "Pro" unlock is processed entirely by Apple through the App Store. The developer never sees your payment details.
