Libby

Libby is the definitive, free-to-use digital library platform designed to connect users, including children and families, with their local public library's collection of ebooks, audiobooks, and digital magazines. Available globally on both iOS and Android devices, Libby transforms the traditional library experience by allowing users to instantly borrow and enjoy content from anywhere, all without fees or subscription costs, simply by using a valid library card. The platform, created by OverDrive, is dedicated to intellectual freedom and broad access, offering an extensive catalog that includes titles for all ages, from young children to mature adults, making it an indispensable resource for family reading and education (Target Age: 6–12+). A core feature of Libby, and one of its most important from a family safety perspective, is the **Content Controls** capability. This functionality allows parents to meticulously manage the types of content visible to their children while browsing and searching within the app, ensuring that screen time remains productive and age-appropriate. Unlike simple content filters, Libby's Content Controls are robust settings that govern the visibility and accessibility of titles based on four distinct audience categories: Juvenile, Young Adult, General Content, and Mature Content.

The four audience categories are defined as follows: **Juvenile** titles are intended for younger readers, typically ages 0–12. **Young Adult** titles are for readers ages 13–18. **General Content** covers titles written for adult readers or a general audience, representing the majority of the collection. Finally, **Mature Content** is intended only for adult audiences due to the explicit nature of the material. Parents have the option to apply simplified content control **Presets** for common use cases. The **Libby for Kids** preset is specifically designed for devices used by children, restricting all searching and browsing to only show Juvenile and Young Adult titles, while effectively hiding General Content and Mature Content. This is the recommended setting for a device that a child uses unsupervised. Conversely, the **Libby for Grown-ups** preset is available for adult users who wish to exclude all children’s and young adult titles from their searches and browsing, though this can be toggled to include Young Adult content if desired.

Beyond the presets, parents can customize controls for specific types of content, particularly Mature Content. Within the settings menu, a user can choose to disable options like Allow in deep search, Allow samples, Allow loans & holds, and Show cover images for mature content. This level of granular control minimizes the chance of a child accidentally encountering explicit material while still maintaining full access for adult users on a separate, dedicated device. any Content Controls set are applied across *every* library card and collection linked to the Libby app on that specific device, providing consistent, universal protection. To prevent a child from easily altering these parental protections, Libby includes an essential security feature: the ability to lock the Content Controls settings with a **passkey**, requiring parental approval to make any changes. Libby prioritizes the convenience and accessibility of reading. Borrowed books are automatically returned, eliminating late fees, and the platform offers the convenience of full **Offline Availability**, allowing children to download books and audiobooks and enjoy them without needing a Wi-Fi connection, perfect for travel or managing data usage.

The app’s reader and audiobook player feature customizable options, including adjustable playback speed, font size, lighting, and a sleep timer to support comfortable and controlled reading experiences. The creators, OverDrive, emphasize their deep commitment to user **Privacy** and data security. The company explicitly states that they will not sell users' personally identifiable information (PII) and will not use or disclose PII for third-party advertising, and there are no ads present in the app. Data collected is limited to what is necessary for the service to function, such as library credentials, borrowing history, and reading progress, to enable features like synchronization across devices. While the platform does collect some sensitive data like location (if the user opts in to find local libraries) and build fingerprint, all data is handled with a comprehensive security program, including encryption at rest and in transit. Furthermore, while Libby now uses generative artificial intelligence models to provide on-demand title recommendations, the company assures that it does *not* share any identifying data about the user or their usage with these AI models.

By leveraging these powerful, easy-to-use parental controls, Libby provides a secure, vast, and free resource for encouraging literacy and a love of reading in children and teenagers (Age 6–12+). The overall high Parent Safety Score is maintained when the Content Controls are utilized correctly. Libby should be reviewed in real family use before recommendation. Test first-session onboarding, age fit (6–12+), data collection prompts, and monetization flows. Verify whether core tasks remain usable with limited connectivity, whether navigation is predictable for children, and whether adult controls are easy to find. Keep short supervised sessions and document where children need support.
