Terms of Use

Last updated: May 05, 2025

1. Introduction

ArtistAssistApp ("Web App") provides tools to assist artists with various aspects of their creative process, including color mixing, image manipulation, image style transfer, tonal value studies, and grid generation for accurate drawings. These services run entirely in the browser and require no account creation or direct payments through the Web App.

The Web App is developed and operated by Yevhen (Eugene) Khyst, a sole trader based in Ukraine. Access is provided globally. Subscription management (including sign‑up, cancellation, and refunds) is handled exclusively via our Patreon page.

2. Definitions

• Free Features: The set of tools available without subscription, including basic color brands and basic image processing modes.
• Premium Features: The complete set of features unlocked by a paid membership on Patreon, including 200+ color brands and advanced image processing modes.

3. Acceptance of Terms

By accessing or using the Web App, you acknowledge that you have read, understood, and agree to be bound by these Terms. If you do not agree, please discontinue use immediately.

You must be at least 13 years old (or whatever higher minimum age your jurisdiction requires) to use the Web App. If you are below that age, you may only access the Web App with parental or guardian consent and supervision.

4. Access and Subscriptions

4.1 Free Features

The Web App provides a set of features available at no cost. These Free Features allow users to explore the platform's functionality before deciding to purchase a paid membership on Patreon. Free Features may include basic image processing tools and limited access to color brands. The scope of Free Features may change at our discretion without notice.

4.2 Patreon Subscriptions

Access to Premium Features is granted by becoming a paid member on our Patreon page.

Premium Features include, but are not limited to:

• Access to over 200 color brands
• Advanced image-to-outline transformation
• Enhanced background removal
• Additional image style transfer options
• An ad-free experience

All paid memberships and associated benefits are managed through Patreon. Please visit our Patreon page https://www.patreon.com/artistassistapp to subscribe, change your membership level, or cancel your paid subscription.

For the full Patreon policy, please see Patreon's Policy.

4.3 Subscription Terms

Subscriptions operate on the billing cycle defined by Patreon. Recurring paid subscriptions will be processed automatically by Patreon until you cancel your paid subscription.

You may cancel or modify your Patreon paid subscription at any time via the Patreon website. Cancellation stops future charges but does not affect access to Premium Features until the end of your current billing period as determined by Patreon.

Any changes to membership levels or benefits will be communicated via Patreon. Continued use after such changes constitutes acceptance of those changes.

5. Refund Policy

All refund requests for paid memberships are handled according to Patreon's refund policy. Because payments are processed through Patreon, we do not issue refunds directly. Please review their policy for full details on eligibility and procedures.

6. Device Compatibility

The Web App is designed to perform optimally on desktop and mobile devices, including PCs, laptops, tablets, and smartphones. To ensure full functionality, please verify that your device's operating system and browser meet our minimum system requirements. We recommend testing the Free Features to confirm compatibility before subscribing via Patreon.

We reserve the right to update system requirements and will provide notice of any changes.

7. Data Accuracy and Limitations

• Data accuracy: The data provided on the Web App, including information about color sets, paint properties, paint colors, and related content, is intended for informational purposes only. While we strive to maintain accurate and up-to-date information, users should be aware that the data may contain errors, omissions, or inaccuracies.
• Not professional advice: The data on the Web App is not intended to constitute professional advice, recommendations, or opinions in any field, including but not limited to art, painting, or any related discipline. Users should not rely on the data provided on the Web App as a substitute for seeking professional advice or expertise.
• Consult experts: If you require precise or expert advice on color sets, paint properties, paint colors, or related matters, we strongly recommend consulting with knowledgeable experts or professionals who can provide tailored guidance based on your specific needs and circumstances.
• Use at your own risk: Your use of the data on the Web App is at your own risk. We disclaim any liability for any actions taken or decisions made based on the data presented. Users are encouraged to independently verify any information obtained from the Web App before making any decisions or taking any actions.
• Color mixing model limitations: The Web App uses an empirical model to simulate real color mixing. This model is simplistic and does not take into account many factors that are present in reality. The model does not pretend to be scientifically accurate and is intended primarily to produce plausible results for artists. For critical color work, we recommend using physical samples to verify colors.
• sRGB color space limitations: The Web App heavily utilizes the sRGB color space for calculations, which has a limited color gamut. As a result, some colors, especially those outside the sRGB color gamut, may not be accurately represented on the Web App. Users should be aware that colors displayed on the Web App may not precisely match real-world colors due to the limitations of the sRGB color space. Calibrate your monitor regularly to ensure proper color accuracy. For critical color work, we recommend using physical samples to verify colors.
• Dataset and algorithms updates: The Web App may update or revise its datasets, color libraries, or algorithms at any time without prior notice. These changes are intended to enhance accuracy and user experience.
