Privacy Policy
This privacy policy applies specifically to EarnLock.
Overview
EarnLock is built with a single privacy stance: your data stays on your device. There is no EarnLock server. Nothing you do in the app is transmitted to us or to any third party. This page exists to describe what data the app uses and why — not to ask for your trust on top of vague promises. In one sentence: EarnLock reads your Apple Health activity data and your selection of blocked apps on-device only, stores them on-device only, and uses them on-device only to decide whether your daily goal is met. We never see any of it. Apple's App Privacy nutrition label confirms "Data Not Collected" for every release of the app.
Data Collection
EarnLock does not collect personal data. It reads three categories of on-device information for the sole purpose of running the daily-goal lock: (1) HealthKit activity data — your daily step count, active energy burned, and exercise minutes — to evaluate progress against the daily activity goal that unlocks your selected apps. HealthKit is read only (we never write to Health), read only on your device, and never transmitted off-device by EarnLock. Apple's HealthKit framework itself does not share this data with us or with third parties. You can revoke EarnLock's Health access at any time in iOS Settings → Privacy & Security → Health → EarnLock. (2) Family Controls tokens for the apps you choose to block — when you pick apps in iOS's Family Controls picker, iOS hands EarnLock an opaque token for each selected app, not the app's name, identifier, or icon. These tokens are stored on your device only, in an App Group container shared between the EarnLock app and its iOS extensions (Shield, Shield Action, DeviceActivityMonitor, Live Activity / widget extension). The tokens are opaque by Apple's design — even EarnLock cannot read which app the user selected. The selection is never transmitted off-device, and you can clear it at any time from the EarnLock home screen (Settings → Blocked apps → Edit). (3) StoreKit transactions — when you subscribe or purchase Lifetime, Apple sends EarnLock a verified transaction object containing only the product ID and entitlement status. There is no payment information, name, email, or other personal data visible to the app. All payment processing, refund handling, and subscription management is performed by Apple's StoreKit and the App Store, not by EarnLock. EarnLock writes only a single boolean (isPremium) into the App Group container so widgets and the Apple Watch app can render the right state.
Data Storage & Processing
All EarnLock data is stored locally on your device, inside the app's sandbox and an App Group container shared with EarnLock's iOS extensions. There is no EarnLock backend at all — no servers, no databases, no analytics pipeline. Streak history, reflection log entries, screen-time-saved estimates, and your selection of blocked apps live in standard Apple containers that iOS Backup includes if you enable iCloud Backup. Deleting the EarnLock app from your device removes its container, the App Group container, and everything inside them.
Third-Party Services
EarnLock does not use third-party analytics, advertising, or tracking services. It uses no third-party SDKs of any kind — no Firebase, Mixpanel, Amplitude, Segment, Sentry, Bugsnag, ad networks, or attribution networks. EarnLock uses only Apple's own frameworks: SwiftUI, SwiftData, HealthKit, FamilyControls, ManagedSettings, DeviceActivity, ActivityKit, WidgetKit, WatchConnectivity, and StoreKit 2. Apple processes limited data as part of services you choose to use, such as App Store purchases, HealthKit access, and Apple Watch connectivity — none of that data flows to EarnLock as the developer.
Health & Sensitive Data
EarnLock reads HealthKit activity data (steps, active energy burned, exercise minutes) and, with your explicit permission, iOS Screen Time data for the apps you have shielded, to compute the conservative screen-time-saved estimate. All of this is read on-device only and never transmitted off the device. EarnLock does not sell, share, or use this data for advertising purposes. It is not used outside the app's own goal-tracking and insights features.
Children’s Privacy
EarnLock is intended for adults using the app on their own iPhone, and authorizes Apple's Family Controls framework in the .individual mode only — never in the .child mode used for parental controls over a Family Sharing minor. EarnLock is self-restriction software, never parental control. We do not knowingly collect any data from anyone, of any age.
Changes to This Policy
If this policy changes, the "Last updated" date at the top of this page changes. Material changes will be noted in the app's release notes on the App Store.
