Why On-Device Data Storage Matters for Your Health App
Health data is among the most sensitive personal information you generate. Your step patterns reveal your daily routine, your location, your work schedule, and your lifestyle habits. Who has access to this data — and what they do with it — matters.
The Problem with Cloud-Based Health Apps
Many fitness apps use a 'free service, data as payment' model. Your health data is uploaded to their servers, analyzed, aggregated with millions of other users, and often shared with third-party advertisers, data brokers, or insurance companies. You agree to this in a terms of service document almost nobody reads.
Common Ways Health Apps Use Your Data
- ✓Selling aggregated health trends to pharmaceutical companies
- ✓Sharing location data with advertising networks
- ✓Providing data to health insurance companies (in some regions)
- ✓Training AI models on your personal health patterns
- ✓Selling user profiles to data brokers
Steply's On-Device Approach
Steply takes the opposite approach. All your step data, GPS routes, analytics, and personal settings are stored exclusively on your iPhone — in the local app database. Nothing is uploaded to Steply's servers because Steply doesn't have servers that store user data.
No Account
Zero sign-up required
No email, no password, no profile. You open the app and it works. Nothing to hack, nothing to breach.
No Cloud Upload
Stays on your device
Your data never leaves your iPhone unless you explicitly export it yourself. No background syncing to remote servers.
No Ads
No tracking either
No ad SDKs, no analytics trackers, no third-party frameworks that phone home with your usage data.
Apple HealthKit Integration
Steply integrates with Apple HealthKit, which means your steps can be shared with Apple Health — but this happens locally on your device, under your control. You can revoke this permission at any time in your iPhone's Privacy settings. HealthKit data never passes through Steply's infrastructure.
