Privacy Policy
Last updated: 12 April 2026
Privacy is at the foundation of WayBalance. We built an app that keeps your health data where it belongs — on your device and in your private iCloud account. This policy explains exactly what we do and don't collect.
The Short Version
- All your health data (weight, BMI, water, steps) is stored on your device using SwiftData
- We use only anonymous, aggregated analytics via TelemetryDeck — we cannot identify you
- No account required — no email, no password, no sign-up
- iCloud sync is handled entirely by Apple's CloudKit — we cannot access your synced data
- We never sell, share, or trade your data with anyone
What Information We Collect
Information You Provide
When you use WayBalance, you may enter health-related information including weight entries, water intake logs, and profile details such as height and gender. All of this data is stored locally on your device using Apple's SwiftData framework. We do not have access to this information.
Apple HealthKit
With your explicit permission, WayBalance integrates with Apple HealthKit to read and write health data:
Read from Apple Health:
- Daily step count
- Active energy (calories burned)
- Walking + running distance
- Flights climbed
- Weight entries from other apps (smart scales, MyFitnessPal, etc.)
Write to Apple Health:
- Weight entries logged in WayBalance
- BMI calculations based on your logged weight and height
Weight data syncs both ways — entries you log in WayBalance appear in Apple Health, and entries from other health apps appear in WayBalance. You control which permissions are enabled in Settings > Health > WayBalance.
HealthKit data is governed by Apple's strict privacy policies. We do not access HealthKit data on any server — it stays entirely on your device. We do not use HealthKit data for advertising or data mining, in accordance with Apple's HealthKit guidelines.
Optional iCloud Sync
If you have iCloud enabled, WayBalance uses Apple's CloudKit to sync your data across your Apple devices. This data is stored in your private iCloud container, encrypted with your Apple ID credentials. We as the developer cannot read, access, or decrypt this data.
Information We Don't Collect
- Personal information (name, email, phone number, Apple ID)
- Location data or GPS coordinates
- Device identifiers or advertising IDs
- IP addresses
- Your health data (weight, BMI, water intake, step counts)
- Payment information (handled entirely by Apple)
How We Use Your Information
All calculations and data processing happen locally on your device. Your weight trends, BMI calculations, water tracking, and step insights are computed entirely on your iPhone or Apple Watch. No health data is sent to any server.
Anonymised Analytics
We use TelemetryDeck for privacy-friendly, anonymised analytics.
What We Collect (Anonymously)
- Which features are used most (e.g. weight logging vs water tracking)
- App version and iOS version
- Device type (e.g. iPhone 15, Apple Watch Series 9)
- General performance metrics
- Crash reports
- Country-level location only
What We DON'T Collect
- Any health data whatsoever
- Any personally identifiable information
- Your Apple ID or device serial number
- Precise location
- Your name, email, or any contact information
How Anonymisation Works
TelemetryDeck uses a salted hashing algorithm to create anonymous user signals. This means we can understand aggregate usage patterns (e.g. “60% of users log water daily”) without being able to identify any individual user.
Why We Use Analytics
Anonymous analytics help us understand which features matter most so we can prioritise improvements. For example, if we see that water tracking is heavily used, we invest more in making it better.
Opt-Out
You can disable analytics in the app's Settings. When disabled, no signals are sent to TelemetryDeck at all.
Data Sharing
We do not sell, rent, or trade your data. The only third parties that may process data in connection with WayBalance are:
- Apple App Store — processes payments and provides us with anonymised sales data only
- Apple CloudKit — syncs data to your private iCloud container (we cannot access it)
- Apple HealthKit — reads/writes health data on your device only (no server access)
- TelemetryDeck — receives anonymised, aggregated analytics signals only
Data Security
- Your data is protected by iOS device encryption
- iCloud data is encrypted with your Apple ID credentials
- We have no servers storing your data — there is no server to breach
- App data is sandboxed and inaccessible to other apps
Your Rights
- Access — all your data is visible directly in the app
- Deletion — delete individual entries in the app, or delete the app entirely to remove all local data
- Disable sync — turn off iCloud sync in your device Settings
- Disable analytics— turn off analytics in the app's Settings
- Disable HealthKit— revoke HealthKit permissions in Settings > Health > WayBalance
Children's Privacy
WayBalance is not directed at children under the age of 13. We do not knowingly collect information from children. The app tracks health metrics intended for adult use.
International Users
Since we do not collect or process personal data on any server, we believe our obligations under GDPR, UK GDPR, CCPA, and similar regulations are minimal. Your data stays on your device and in your private iCloud — both controlled entirely by you and Apple.
Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be reflected by an updated date at the top of this page. For significant changes, we will provide notice through the app or App Store release notes.
Third-Party Services
WayBalance integrates with the following third-party services. Each has its own privacy policy:
