Privacy Policy

Last Updated: July 2026

We value your privacy. This Privacy Policy explains how the Nepsis application (hereinafter referred to as the "Application") handles user data.

1. Local-First Architecture

The Application is designed based on a "local-first" architecture. This means that:

We do not create user accounts (there is no registration required by name, phone number, or email).
We do not operate our own servers to collect or store your personal usage data.
All data related to the use of the Screen Time API (app usage time, blocks, and restrictions) is processed exclusively locally on your iOS device. The Application developer has no technical means to access this information.

2. Use of Screen Time API (FamilyControls)

The Application utilizes Apple's Screen Time API features to monitor and limit the time spent on other applications. All permissions are requested via standard iOS system dialogs. The data from this API is protected by Apple's built-in security mechanisms, never leaves your device, and is not used for advertising purposes.

3. Optional iCloud Sync

If you enable iCloud sync in the Application, certain rule metadata is synchronized between your Apple devices through Apple's iCloud Key-Value storage. This may include:

Rule names, schedules, and protection settings
Strict mode and passcode protection preferences (passcode itself is stored locally in the iOS Keychain — see Section 5)

iCloud sync is optional and controlled by you in the Application settings. Data synced via iCloud is subject to Apple's Privacy Policy.

Important: Due to Apple platform limitations, Screen Time app and category selections (tokens) cannot be synced between devices. After syncing, you may need to re-select apps on each device.

4. Third-Party Services and Subscription Data Processing

To provide and manage in-app purchases and subscriptions, the Application utilizes a third-party service, RevenueCat (RevenueCat, Inc.).

RevenueCat collects and processes the following anonymized data:

Identifiers: A random, anonymous alphanumeric identifier (User ID), automatically generated for your device to verify your subscription status.
Purchase History: Transaction information (purchase date, subscription type, renewal status) processed via encrypted Apple purchase receipts.

This data is transmitted to RevenueCat in an encrypted and strictly anonymous format. It is required solely to ensure the application's core functionality (verifying Premium access) and for internal sales analytics. This data is not linked to your identity and is not used for tracking across advertising networks.

You can review the service's privacy policy on their official website: RevenueCat Privacy Policy.

5. Passcode and Local Storage

If you enable Strict mode or passcode protection, your passcode is stored locally in the iOS Keychain on your device. It is never transmitted to us, RevenueCat, or any third party.

The Application may store non-sensitive preferences and local insights (such as usage summaries derived from Screen Time data) on your device only. This information is not sent to external servers.

6. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Changes become effective immediately upon their publication on this page. We recommend regularly checking this page for updates.
