Privacy Policy

Last updated: October 22, 2026

This Privacy Policy explains how Nalod Associates LLC ("we," "us," or "our") collects, uses, and protects your information when you use The Musky Library (the "Service"). The Service is offered to users in the United States and Canada. By using the Service, you agree to this Policy.

Information We Collect

  • Account information. Such as your email address, used to create and secure your account and to sign you in across devices.
  • Content you create. Lures, catches, depth logs, waypoints, notes, photos, and related details you add to the app. This includes the catch locations described in "Location Information" below.
  • Subscription information. If you purchase Pro, your purchase is processed by Apple. We receive confirmation of your subscription status but do not receive or store your full payment-card details.
  • Usage & diagnostic data. Limited analytics and technical information (such as app interactions, device and app version, and crash data) that help us understand and improve how the Service works. When you are signed in, this data is linked to a random account identifier, not to your name or email address.
  • Notification information. If you allow notifications, we store your device's push-notification token, along with your app version, so we can send notifications to your device. You can turn notifications off at any time in the app or in your device settings.

Location Information

  • Catch locations. When you log a catch, you can enter the lake, nearest town, and state or province. The app converts what you enter into approximate map coordinates and a time zone, and uses them to calculate the sun and moon (solunar) conditions at the time of your catch. These details are saved with the catch and synced to our servers as part of your content.
  • Your device's location, for weather. If you give permission, the app uses your device's location while the app is open to show the weather where you are. Your device sends this location directly to Apple to fetch the weather. We do not store your device's location on our servers, and we do not attach it to your catches or your account. You can decline or turn off location access at any time in your device settings, and you can search for a place instead.
  • Places you search for or save. Weather places you search for or save are kept on your device and are not sent to our servers.

The app uses Apple services for weather (Apple Weather) and for place search and converting place names into coordinates (Apple Maps). To provide these features, the location, place names, or search text involved are sent to Apple. Apple's handling of this information is governed by Apple's Privacy Policy.

How We Use Your Information

We use your information to:

  • provide, maintain, sync, and back up the Service and your data;
  • provide weather, forecast, solunar, and fishing-window features, and show conditions for your catches;
  • send notifications you have chosen to receive;
  • process and manage subscriptions;
  • respond to your support requests;
  • improve and secure the Service and prevent abuse; and
  • comply with legal obligations.

We Do Not Sell or Share Your Personal Information

We do not sell your personal information, and we do not share it for cross-context behavioral advertising or any similar purpose. We have no advertising trackers in the Service. We work with a small number of trusted service providers to operate the Service on our behalf — for authentication and database hosting, backend infrastructure hosting, media (photo) storage, subscription management, product analytics, crash and error diagnostics, weather and mapping services, and push-notification delivery. These providers act as our processors and are not permitted to use your information for their own purposes.

Service Providers

The providers we rely on may process your information only as needed to deliver their function (for example, storing your account and content, hosting your photos, confirming your subscription, or aggregating usage analytics). We do not authorize them to sell or independently use your information.

Aggregated & De-Identified Data

We may create aggregated or de-identified information that cannot reasonably be used to identify you — for example, combined statistics about fishing conditions, weather, sun and moon conditions, lures, and catch patterns across many users. We may use and retain this information for any purpose, including to analyze trends and to develop, improve, and promote the Service. We maintain and use such information only in de-identified form and do not attempt to re-identify it.

Data Retention & Your Choices

We keep your information for as long as your account is active or as needed to provide the Service.

When you delete an item (a lure, catch, depth log, or waypoint), it is removed from your devices and hidden from your account immediately. For up to 60 days, a copy is retained on our servers in order to synchronize the deletion across your devices; after that period it is permanently purged.

Information kept only on your device, such as saved weather places, is removed when you delete the app.

When you delete your account, all of your data — including any items pending deletion — is permanently and immediately removed. You can delete your account at any time in the app (Settings → Account). If you need help, email [email protected] and we'll take care of it. You may also request access to, or correction of, the personal information we hold about you.

Security

We use industry-standard measures to protect your data in transit and at rest. No method of transmission or storage is 100% secure, but we work to safeguard your information.

Children's Privacy

The Service is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided us personal information, contact us and we will delete it.

Your Regional Rights

Depending on where you live (including under California and Canadian privacy laws), you may have rights to access, correct, or delete your personal information, and to not be discriminated against for exercising those rights. Because we do not sell or share personal information, no "Do Not Sell or Share" action is required. To delete your data, delete your account in the app (Settings → Account). For access, correction, or any other request, email us below.

Changes to This Policy

We may update this Privacy Policy from time to time. We will let you know about material changes in the app and by updating the "Last updated" date above.
