Privacy Policy

1. Overview

North Star Labs LLC ("we," "us," or "our") respects user privacy and is committed to protecting personal information. This Privacy Policy applies to our marketing website and our mobile applications, including ScrollToll (the "App").

Our products are designed to support focus and intentional device usage while minimizing data collection.

2. Screen Time & App Usage Controls

Our App uses Apple's Screen Time features to provide app-shielding and productivity functionality.

Local Processing: All app usage settings, category selections, and shielding configurations are processed locally on the user's device.

No App Usage Collection: We do not collect, store, or transmit information about the specific apps you use, your browsing activity, or your device usage.

No Third-Party Sharing: We do not share any Screen Time–related or app usage data with third parties.

3. Data Collection

Website
Our marketing website does not currently collect, store, or process personal data from visitors.

Applications
Our applications may offer optional user accounts (e.g., "Pro" membership) to provide access to premium features.

AI-Powered Features (Pro Members)
For Pro members, we may offer features that use a Large Language Model (LLM) to generate content, such as question packs. To enable this functionality:

• We send the text-based input you provide to a third-party LLM.
• The LLM processes this input and returns the generated content to you within the App.
• To maintain and improve the service, we may temporarily log your input. We do not use your input to train the LLM.

Our applications may log some non-identifying Screen Time or app usage data to our servers for service improvement, but do not transmit this data for primary app functions.

4. Third-Party Services

Subscription Processing
We use RevenueCat to process in-app subscriptions. RevenueCat may collect anonymous identifiers and transaction data to manage purchases. We do not receive or store your payment information directly—all payment processing is handled by Apple through the App Store. For more information, see RevenueCat's Privacy Policy.

AI Content Generation
We use Anthropic's Claude to power our AI-based features. When you use these features, your input is sent to their service for processing. We do not share your personal information with this provider. For more information, see Anthropic's Privacy Policy.

Push Notifications
If you enable push notifications, your device token is sent to our server (hosted on AWS) to deliver relock reminder notifications. Device tokens are anonymous identifiers that do not personally identify you. We use these tokens solely for delivering notifications and do not share them with third parties.

5. Children's Privacy

Our applications are intended for individual users and are not designed specifically for children. We do not knowingly collect personal information from children.

6. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last updated" date.
