Nook Privacy Policy

Last updated: May 27, 2026

Nook is a personal saved-link library. This policy explains what Nook collects, why it is used, and how you can control it.

Information We Collect

• Account information: Apple sign-in identifiers, email address if Apple shares it, and the name you provide in Nook.
• Saved content: URLs you save, preview metadata, notes, reason tags, timing tags, kindling dates, and related AI-generated labels or summaries.
• Search and AI requests: search text, saved-link context, page text, URLs, and notes may be sent to Nook's backend so the app can generate summaries, labels, and search results.
• Subscription information: RevenueCat and Apple provide purchase, product, entitlement, renewal, and restore status. Nook does not receive your payment card details.
• Diagnostics and service logs: app and backend logs may include request metadata, errors, usage counters, device/app context, IP address, and timestamps needed to operate and secure the service.
• Clipboard URLs: Nook checks for a copied URL on-device. A URL is saved only if you choose to save it.

How We Use Information

We use information to provide Nook's core features: saving links, creating previews, syncing your library, searching your saves, creating reminders, processing subscriptions, restoring purchases, providing support, preventing abuse, and improving reliability.

AI Processing

Nook uses backend AI services to create summaries, labels, and search results. Nook does not use your saved content, notes, or searches to train AI models. API keys stay on the backend.

Third-Party Services

Nook relies on service providers including Apple, Supabase, RevenueCat, OpenAI, Google Maps, and backend hosting providers. These providers process data only as needed to provide authentication, sync, subscriptions, AI metadata, map previews, hosting, security, and support.

Selling, Ads, and Tracking

Nook does not sell personal data. Nook does not share personal data for third-party advertising or cross-app tracking. Nook does not use the iOS advertising identifier.

Retention and Deletion

Local data stays on your device until you delete it or delete the app. If sync is enabled, synced data is kept until you delete items or delete your account. Settings includes account deletion, which requests deletion of account data and clears local Nook data from the device.

Your Choices

You can export a local JSON copy to your clipboard, restore purchases, sign out, delete saved items, delete your account in Settings, and manage app permissions such as notifications in iOS Settings. You can request access, correction, deletion, portability, or other privacy help by emailing [email protected].

Children

Nook is not directed to children under 13.
