Privacy Policy

Last updated: September 9, 2025

This Privacy Policy describes how 66Colorful (“we,” “us,” or “our”) collects, uses, and safeguards information when you visit 66colorful.com and use our color tools, including image-based features such as palette extraction and pixel color picking.

Quick Summary

  • We collect only what we need to operate and improve the site (usage data, device information, error logs, and optional messages you send us).
  • When you use image tools, images are processed solely to provide the requested result. We do not use your images to train models or build a dataset.
  • We use cookies and local storage to remember preferences (e.g., theme, recent colors/palettes) and to measure site usage.
  • We do not sell your personal information. If we ever introduce advertising that qualifies as “sharing” under applicable laws, we will update this Policy and our cookie banner.

Scope

This Policy applies to 66colorful.com and any pages where it is linked. It does not cover third-party websites, tools, or services that we don’t control.

Information We Collect

1) Information you provide directly

  • Contact messages. When you contact us (e.g., email or form), we receive the content of your message and contact details.
  • User submissions. If you voluntarily send feedback, bug reports, or suggestions, we process those to respond and improve our services.

2) Information collected automatically

  • Usage & diagnostics. Pages viewed, tool interactions (e.g., running a converter or checker), timestamps, referrer, and basic device information (browser type/version, language, operating system).
  • Log data & security signals. IP address, request/response metadata, and error logs used to operate the site, prevent abuse, and troubleshoot issues.
  • Cookie/local storage data. Preferences such as theme, recent searches/colors, and tool settings saved in your browser for convenience.

3) Images and content used in tools

Some tools let you upload or paste images/URLs (e.g., “Palette from Image” and “Image Color Picker”). We process the image solely to extract colors or generate the result you requested; we do not use your images for any other purpose. Where technically feasible, processing happens in your browser. If a server-side step is needed (for compatibility, performance, or URL proxying), any transient copy is used only to complete the request and is not retained longer than necessary for the operation of the tool.

How We Use Information

  • Provide and operate the tools (e.g., color conversions, contrast checks, palette extraction, image sampling).
  • Improve and debug site performance, quality, and usability (including analytics and diagnostics).
  • Security and abuse prevention (detecting anomalies, rate limiting, protecting against DDoS or misuse).
  • Legal compliance and to enforce our Terms of Use.
  • Communicate with you (respond to inquiries and support requests).

Cookies, Local Storage & Similar Technologies

We use:

  • Strictly necessary items (e.g., session management, load balancing, security).
  • Preferences (e.g., UI theme, last used tool settings, recent colors).
  • Analytics to understand aggregate usage and improve features.

You can control cookies via your browser settings. Blocking some types may affect site functionality. If we later implement a cookie banner or “Cookie Settings,” that control will supplement your browser settings.

Third-Party Service Providers

We use service providers to host the website, deliver content efficiently (e.g., via content delivery networks), protect against abuse, measure aggregate usage, and support error monitoring. These providers act on our instructions and are bound by confidentiality and data-protection obligations. We do not permit them to use your personal information for their own independent purposes.

Legal Bases (EEA/UK only)

If you are in the EEA/UK, we process personal data under these bases:

  • Contract/legitimate interests to provide and improve the site/tools and ensure security.
  • Consent for non-essential cookies/analytics where required.
  • Legal obligation where we must retain certain records.

Data Retention

  • Images used in tools: kept only for the duration necessary to generate your result and then discarded (we do not build an image dataset).
  • Logs/diagnostics: retained for a period appropriate to security, operations, and compliance needs, and then deleted or anonymized.
  • Contact messages: retained as needed to respond and maintain records.

Data Security

We use reasonable technical and organizational measures to protect information (e.g., encrypted transport via HTTPS, access controls, least-privilege practices). No internet service can be 100% secure, but we work to protect data from unauthorized access, alteration, disclosure, or destruction.

International Data Transfers

We may process and store information in countries other than where you live. Where required, we use appropriate safeguards (such as standard contractual clauses) to protect your information when it is transferred internationally.

Your Rights & Choices

EEA/UK/Swiss residents

You have the right to request access, correction, deletion, portability, or restriction of your personal data, and to object to processing in certain cases. Where we rely on consent, you may withdraw it at any time.

US residents (including California)

We do not sell your personal information. If we ever engage in activities that constitute “sharing” for cross-context behavioral advertising, we will provide an opt-out mechanism and update this Policy. You may request access, deletion, or correction of personal information, and to limit the use of sensitive personal information (if any).

Children’s Privacy

66Colorful is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child provided personal information, please contact us so we can delete it.

Third-Party Links

Our site may link to third-party sites or resources. Their practices are governed by their own privacy policies, not this one.

Do Not Track

Some browsers send “Do Not Track” signals. Because there is no consistent industry standard, we do not respond to DNT at this time.

Changes to This Policy

We may update this Policy to reflect changes to our practices, technologies, or legal requirements. When we post changes, we will revise the “Last updated” date and, where appropriate, provide additional notice.
