Stuie: Steps to Unlock — Privacy Policy

Operated by HarSivo Labs · Effective 15 September 2026

Stuie is an iOS and iPadOS Screen Time app that turns your real Apple Health steps into short, timed access to apps you choose to block. This policy explains what data Stuie uses, where it stays, and which service providers receive information.

The short version: Stuie has no accounts, no advertising, and no cross-app tracking. Your step count and Screen Time data stay on your device. RevenueCat manages the optional Premium subscription and never receives your Health or Screen Time data.

1. Apple Health (HealthKit) data

• Stuie requests read-only access to one data type: step count. It never writes to Apple Health and never reads any other health data.
• Stuie reads today's cumulative step total to show your available step balance and determine whether you have earned an unlock.
• Step data is processed entirely on your device. It is never uploaded, transmitted, sold, or shared with HarSivo Labs, RevenueCat, or any other third party.
• Health data is never used for advertising, marketing, data mining, or any purpose other than Stuie's step-to-unlock feature.
• You can revoke access at any time in Apple Health under Sharing → Apps and Services → Stuie.

2. Screen Time data

• Stuie uses Apple's Family Controls, Managed Settings, and Device Activity frameworks to shield the apps, categories, and websites you select.
• Your selection is stored on your device as opaque Apple-issued tokens inside Stuie's private app group. Stuie cannot read the names of the apps you select.
• Apple's Device Activity system measures selected-app usage. Stuie's code records only that a configured usage threshold was crossed; detailed reports are rendered inside Apple's sandboxed report extension.
• Screen Time selections and usage information are not transmitted off your device.
• You can stop blocking at any time from the Block tab and revoke Screen Time access in system Settings.

3. Notifications

If you allow notifications, Stuie sends local notifications—for example, to bring you back to your step balance after you tap its shield. Stuie does not send marketing notifications from a server.

4. Premium subscription and RevenueCat

• Blocking is free. Stuie Premium is an optional auto-renewing App Store subscription that lets you spend steps to unlock blocked apps.
• RevenueCat receives an anonymous app-user identifier and App Store purchase information needed to present subscriptions, validate purchases, restore purchases, and determine Premium status.
• Stuie does not send RevenueCat your name, email address, Health data, or Screen Time data.
• RevenueCat handles this information under its Privacy Policy. Payment details are handled by Apple and are not visible to Stuie or HarSivo Labs.

5. Information stored on your device

Stuie stores your steps-to-minutes exchange, spent-step balance, unlock history, walking streak, Stuie's health score, blocking state, and selected Screen Time tokens locally in its sandbox or private app group. You can reset progress inside Stuie. Deleting the app removes its remaining local data.

6. Tracking and advertising

• Stuie has no advertising or cross-app tracking.
• Stuie does not use Health or Screen Time information for analytics, advertising, or marketing.
• Stuie does not collect names, email addresses, phone numbers, location, contacts, photos, or advertising identifiers.

7. Retention, deletion, and your choices

Local information remains on your device until you reset progress or delete Stuie. You can revoke Health, Screen Time, and notification access through Apple system settings. Apple and RevenueCat retain purchase records as needed to provide subscription, entitlement, and restore functionality. Because Stuie has no user accounts, there is no Stuie server-side account to delete.

8. Children

Stuie is not directed at children under 13 and does not knowingly collect personal information from children.

9. Changes to this policy

If Stuie's data practices change, HarSivo Labs will update this page and its effective date.
