Privacy Policy
Effective & Last Updated: November 2026 · Version 1.2
At PigmentLab (pigmentlaboratory.com), we believe creative utilities should be fast, transparent, and private. We operate with a strict client-side first design philosophy: your color recipes, palettes, and mixing experiments are calculated directly inside your browser, never transmitted to or monetized on remote servers.
Key Privacy Guarantees
100% In-Browser Execution
All Kubelka-Munk optical calculations and Itten color wheel operations run on your local device.
Zero Mandatory Accounts
No signup, login, or social authentication required. You can use every tool immediately and anonymously.
We Never Sell Your Data
We do not sell, rent, or trade your personal information or usage habits with third-party data brokers.
1. Introduction & Overview
This Privacy Policy explains how PigmentLab ("we", "us", or "our") handles information when you visit or interact with our website (pigmentlaboratory.com). This policy applies to all pages, tools, and subdomains of PigmentLab.
By accessing PigmentLab, you acknowledge and agree to the practices outlined in this document. If you do not agree with any terms of this policy, please discontinue use of the website.
2. Information We Do Not Collect
To protect your creative freedom and privacy, PigmentLab is deliberately designed without invasive tracking mechanisms:
- No Color Recipes or Palette Logs: The pigments you select, mix proportions, and color wheels generated are not transmitted to or recorded on our servers.
- No User Accounts or Passwords: We do not ask for or store passwords, personal profiles, or payment card data.
- No Cross-Site Tracking: We do not use third-party advertising cookies or cross-site behavioral tracking scripts.
3. Information We May Collect or Store
A. Standard Web Server Logs
Like virtually all web hosts and CDNs, our hosting infrastructure may temporarily process technical access logs when your browser requests web assets. This data may include your truncated IP address, browser type, operating system, referring URL, and the timestamp of the request. These logs are strictly utilized for infrastructure health, DDoS mitigation, and diagnostic troubleshooting.
B. Voluntary Contact Form Submissions
If you choose to communicate with us using our Contact Form or by sending an email directly to contact@pigmentlaboratory.com, we collect only the details you submit: your name, email address, inquiry subject, and message content. This information is used solely to respond to your inquiry.
4. How We Use Browser LocalStorage
PigmentLab uses modern HTML5 localStorage solely to preserve your personal application preferences between sessions. This data resides on your physical machine and is never transmitted to us:
| Storage Key | Purpose | Location & Expiry |
|---|---|---|
| pl_theme | Remembers your dark mode / light mode interface setting | Browser LocalStorage (Persistent until cleared) |
| pl_lang | Stores your interface language preference (e.g. EN, ES, DE, PT) | Browser LocalStorage (Persistent until cleared) |
| pl_pigment_presets_v1 | Stores any custom pigment mix recipes you deliberately save | Browser LocalStorage (Your device only) |
| pl_color_mixer_state_v1 | Preserves your current mixer mode, active pigments, and proportion ratios between sessions | Browser LocalStorage (Your device only) |
| pl_color_wheel_state_v1 | Preserves your selected color wheel model, harmony scheme, angle, saturation, lightness, and vision simulator | Browser LocalStorage (Your device only) |
You can delete these keys at any moment via your browser settings or Developer Tools (Application > Local Storage).
5. Third-Party Services & Hosting
To provide optimal web performance and typographic rendering, PigmentLab utilizes select trusted third-party technical providers:
- Google Fonts: We link to Google Fonts (fonts.googleapis.com) to deliver the Geist Sans and Geist Mono typefaces. Your browser downloads font files directly from Google's edge cache. Google may process your IP address to deliver the font files in accordance with their privacy policy.
- Static Hosting / Edge CDN: Our static pages are distributed globally via high-speed Content Delivery Networks to ensure fast load times and SSL/TLS encryption everywhere.
6. Your Rights Under GDPR & CCPA/CPRA
A. European General Data Protection Regulation (GDPR)
If you reside in the European Economic Area (EEA) or UK, you are entitled to rights including access to your data, rectification, erasure, and restriction of processing. Because we operate without accounts and store no personal identifiers, we hold no user profiles to provide or delete, with the exception of direct email correspondence if you contact us.
B. California Consumer Privacy Act (CCPA / CPRA)
Under California law, residents have the right to know what personal information is collected, request deletion, and opt out of the sale or sharing of personal data. PigmentLab does not sell or share any personal information, nor have we done so in the preceding 12 months.
7. Children's Online Privacy Protection Act (COPPA)
PigmentLab is an educational and creative color utility suitable for general audiences. We do not knowingly solicit, collect, or store personal information from children under the age of 13. If you believe a child under 13 has provided us with personal information via email, please contact us immediately and we will promptly delete it.
8. Security Measures
All traffic to and from PigmentLab is encrypted using standard Transport Layer Security (HTTPS / TLS 1.3). While no method of electronic transmission or storage is 100% impenetrable, our architectural decision not to store user database records inherently minimizes security exposure.
9. Changes to this Policy
We may update this Privacy Policy from time to time to reflect operational or regulatory improvements. Any revisions will be reflected on this page with an updated "Effective Date" at the top of the document.
