Huebook Privacy Policy

Last updated: 25 October 2026

Huebook is a color sampling, palette creation, and color management app for Mac, iPhone, and iPad. This policy explains how Huebook handles your information.

Huebook is provided by José Manuel Sánchez, referred to below as “we.” For privacy questions, contact info@sculptedapps.com.

Your information stays under your control

You do not need to create a Huebook account. Your color library is stored on your device. Optional features let you synchronize it through your iCloud account, export it, or make it available to other apps and tools.

Huebook does not include advertising, advertising tracking, or third-party usage analytics. We do not sell or rent your personal information.

Information Huebook stores

Huebook stores the information needed to maintain your library and preferences, including:

• Colors, palettes, names, notes, groups, tags, favorites, and editing locks.
• Creation dates and information about how a color was added.
• Where available, the name of the app from which you sampled a color.
• Recent color picks, app settings, and counters used to manage free feature limits.

This information is used to provide Huebook’s features. Library records can include personal information if you choose to enter it, for example in a name or note.

Screen, camera, and image access

Screen access on Mac. Huebook uses macOS screen access to provide precision color sampling, Color Scope, contrast analysis, and color-vision simulation. Screen content is processed on your Mac and is not uploaded to us. If you capture or export an image, Huebook may create a local image file.

Camera access on iPhone and iPad. With your permission, Huebook processes camera frames on your device to sample colors. Camera frames are not uploaded to us.

Imported images and files. Huebook processes images and color files you select, drop into the app, or share with it. Image analysis and palette extraction take place on your device. The iOS share extension may store a local copy of a shared image so Huebook can open it. That copy may include metadata contained in the original file.

You can revoke screen or camera permission in your device’s system settings. Features that depend on that permission will then be unavailable.

Optional iCloud synchronization

If you have Huebook Pro and enable iCloud sync, Huebook uses Apple’s CloudKit service to synchronize your color library across your devices. Synchronized records include colors, palettes, names, notes, groups, tags, and associated library metadata.

Apple processes this information through your iCloud account under its Privacy Policy. Huebook does not require your Apple Account password.

Disconnecting iCloud sync stops synchronization on that device. It does not delete existing local or iCloud records.

Purchases

Apple processes Huebook Pro purchases through the App Store. Huebook uses Apple’s StoreKit service to verify your purchase status and purchase date, unlock Pro features, and restore purchases.

We do not receive your payment card details.

Sharing, automation, and AI tools

Huebook shares information when you use features such as export, the clipboard, the system share sheet, Shortcuts, or AppleScript. The information shared depends on the action and export format you choose and may include library metadata.

On Mac, Huebook also offers an optional Model Context Protocol (MCP) server. It is disabled by default and listens only on your computer. When enabled, compatible local software can read colors, palettes, favorites, and source-app information, create palettes, and change favorites.

An AI tool or other application accessing Huebook may send information to its own online services. That processing is governed by the tool provider’s privacy policy and your settings with that provider. You can disable Huebook’s MCP server in Settings.

Retention and deletion

Your saved library remains on your device until you delete its records or remove the app’s stored data. Recent Picks are automatically trimmed according to your selected limit.

To delete synchronized library records across your devices, delete them in Huebook while iCloud sync is enabled and allow synchronization to complete. Turning sync off or uninstalling Huebook does not itself delete iCloud records. You can also manage app storage through Apple’s iCloud settings.

Temporary images and share-extension files may remain until replaced, cleared by the operating system, or removed with the app’s stored data. Exported files and copies shared with other apps remain wherever you saved or sent them. Device backups may retain copies under your backup provider’s settings.

Huebook writes diagnostic messages to system logs to help identify errors. It does not include a third-party crash-reporting service.

Your privacy rights

Depending on your location, you may have rights to access, correct, delete, restrict, or object to the processing of your personal information, and to receive a portable copy. You may also have the right to complain to your local data protection authority.

You can manage much of your information directly in Huebook by editing, exporting, or deleting library records. Contact info@sculptedapps.com for questions or requests concerning information we hold. We cannot directly retrieve information stored only on your device or in your private iCloud account.

If you contact us, we use the information you provide to respond to your request. Where applicable, this processing is based on our legitimate interest in providing support and addressing privacy requests, or on a legal obligation.

Changes to this policy

We may update this policy as Huebook evolves. The date above identifies the latest revision. Where required, we will provide additional notice of material changes.
