Privacy Policy

Nook Focus helps you block distracting apps and websites during focus windows. The app is designed to work without reading your browsing history, website content, screen contents, network traffic, or private messages.

Data Nook Focus Stores

Nook Focus stores the information you enter or select so the app can enforce your focus rules on your device:

• Focus schedules, labels, recurrence settings, and pause state.
• Website domains you explicitly add to Blocked Sites.
• Apple Screen Time selection tokens for apps, app categories, and supported web selections chosen through Apple's picker.
• Local diagnostic events for schedule and blocking validation, such as timestamps, event names, coarse item counts, and error strings.

Apple Screen Time tokens are opaque values provided by Apple. Nook Focus does not convert typed websites into installed apps and does not store app bundle identifiers from your selections.

Data Nook Focus Does Not Collect

• Browsing history or visited URLs.
• Webpage contents, page titles, search queries, or form entries.
• Network packets, DNS logs, proxy logs, or VPN traffic.
• Screenshots, screen recordings, keystrokes, or accessibility observations.
• Screen Time usage reports or remote monitoring reports.
• Precise location, contacts, photos, microphone audio, camera video, or health data.

How Blocking Works

Nook Focus uses Apple-provided Screen Time frameworks, including FamilyControls, ManagedSettings, and DeviceActivity, to apply blocking during active schedules. These APIs let the app ask for authorization, let you select apps or categories through Apple's picker, and apply shields or web-content filters without requiring Nook Focus to inspect browsing content.

App Store builds do not use or expose Safari blocking extension setup for scheduled blocking. Website blocking is handled through the Screen Time path for user-entered domains.

Diagnostics

Nook Focus may write local diagnostic events on your device to help validate that schedules start, end, pause, and resume correctly. These diagnostics are not analytics. They are limited to operational information such as event names, timestamps, source names, coarse token or domain counts, and error strings. They must not include browsing history, visited URLs, page contents, packets, screenshots, or Screen Time usage reports.

Analytics, Ads, and Tracking

Nook Focus does not include advertising and does not track you across apps or websites. The first App Store release is intended to run without third-party analytics. If analytics or crash reporting are added later, this policy and the App Store privacy details will be updated before release.

Data Sharing

Nook Focus does not sell personal data. The app does not send your focus schedules, blocked domains, Screen Time selections, or local diagnostics to Cascade servers in the first App Store release.

Children

Nook Focus is a personal focus tool and is not designed as a remote parental monitoring service. It does not provide parents, guardians, employers, or other people with reports about a user's activity.

Your Choices

• You can edit or delete schedules and blocked sites in the app.
• You can remove app and category selections by editing Blocked Apps.
• You can revoke Screen Time authorization in iOS Settings.
• You can delete Nook Focus to remove app-local data from your device.
