Last updated: 22 July 2026
These Terms of Service ("Terms") govern your use of the mobile application Your Colorbook (the "App"), developed and operated by Lutarea ("we", "us", or "our"). The App is distributed for Apple platforms (iPhone and iPad) and is listed on the Apple App Store under the marketing name Your Colorbook.
By downloading, installing, or using the App, you agree to these Terms. If you do not agree, do not use the App.
1. The App and eligibility
Your Colorbook is a personal color-library application for saving and organizing color swatches used in design and everyday work. Features include a color library with folders, favorites, tags, and search; a color editor with multiple picker modes (spectrum, wheel, classic hue bar, preset grid, RGB sliders, HSL sliders, and HEX entry); display and copy of values in HEX, RGB, HSL, HSV, and CMYK (with opacity); recently copied history; optional JSON backup export and import via the shared Lutarea iCloud Drive container (not CloudKit database sync); onboarding with a sample palette; themes and nine interface languages; and Free-plan limits on how many colors and folders you can create. You must be able to form a binding contract in your jurisdiction and meet any minimum age required by Apple and applicable law to use the App.
2. Apple App Store
If you obtain the App through the Apple App Store, your use is also subject to Apple's applicable terms and rules, including the Apple Media Services Terms and the App Store Guidelines. Apple is not responsible for the App or its content, maintenance, or support, except as required by Apple's policies.
3. License
Subject to these Terms, we grant you a personal, revocable, non-exclusive, non-transferable, non-sublicensable license to install and use the App on Apple devices you own or control, in accordance with the usage rules of the store from which you obtained the App.
- You may not copy, modify, distribute, sell, lease, or reverse engineer the App except where mandatory law allows.
- You may not use the App in any way that violates applicable law or infringes third-party rights.
4. Your content and conduct
You are responsible for the colors, names, descriptions, tags, source links, folders, and other content you create or import into the App. You represent that you have the rights necessary to store that content on your devices.
Optional features may access Apple frameworks you approve in system prompts (for example, iCloud Drive for optional backup, or opening a source URL in the system browser). You control whether those features are used.
5. Backup, import, and export
The App may let you export your library as JSON backup files and import backups you choose (merge or replace). You are responsible for what you share, with whom, and for reviewing imported content before relying on it. Recipients of exported files can read the data you include in those files.
Third-party websites you open via saved source links have their own terms and privacy policies. We are not responsible for third-party services.
6. Changes to the App and Terms
We may update the App or these Terms from time to time. Material changes to the Terms will be reflected by updating the "Last updated" date on this page. Continued use of the App after changes constitutes acceptance of the updated Terms where permitted by law.
7. Disclaimer
The App is provided on an "as is" and "as available" basis, without warranties of any kind, whether express or implied, to the fullest extent permitted by law. We do not warrant that the App will be uninterrupted, error-free, or free of loss of data. Color conversions (for example HEX, RGB, HSL, HSV, CMYK) are provided for convenience and may differ from other tools due to rounding or color-space assumptions. You are responsible for maintaining your own backups using export features where available.
8. Limitation of liability
To the maximum extent permitted by applicable law, Lutarea and its contributors will not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, data, goodwill, or business opportunities, arising out of or in connection with your use of the App. Our aggregate liability for any claim arising from the App will not exceed the greater of (a) the amount you paid us for the App in the twelve months before the claim or (b) zero if the App is free.
Some jurisdictions do not allow certain limitations; in those cases, our liability is limited to the fullest extent permitted.
9. Termination
You may stop using the App at any time by uninstalling it. We may cease providing the App or disable access where required by law or if you materially breach these Terms.
10. Governing law and disputes
These Terms are governed by applicable law without regard to conflict-of-law principles, subject to any non-waivable rights you have under consumer protection rules in your country of residence. Courts or authorities with jurisdiction over disputes may vary by region.
