Privacy Policy

Last updated: April 2026

      DitherLab processes all images entirely in your browser. No image data, personal
      data, or account information is ever collected or sent to any server.
    

1. Data Controller

DitherLab is operated by RDI, St Prex, Switzerland.
Contact for data protection matters: privacy@ditherlab.pro

This policy is governed primarily by the Swiss Federal Act on Data Protection (nDSG, in force since 1 September 2023). Where DitherLab processes personal data of individuals located in the EU/EEA, the EU General Data Protection Regulation (GDPR) also applies to those individuals. Switzerland is recognised as a country with an adequate level of data protection by the European Commission.

2. Data We Collect

DitherLab does not require any account, sign-up, or payment. We do not collect your name, email address, or any other personal data. Images you load into the tool are processed exclusively within your browser and are never transmitted to our servers.

Your browser may store your settings (selected algorithm, palette, slider values) in localStorage on your own device to restore your preferences between sessions. This data never leaves your device.

We do not use analytics cookies, tracking pixels, or advertising scripts.

3. Infrastructure & Third-Party Services

Two third-party services are involved in delivering the page to your browser:

Vercel (vercel.com/legal/privacy-policy) — website hosting. Standard web server logs (IP address, user-agent, requested URL, timestamp) may be retained by Vercel for security and operational purposes. These logs are not under our direct control and are governed by Vercel's own privacy policy.
Google Fonts (developers.google.com/fonts/faq/privacy) — the typefaces used in the interface (Space Mono, DM Sans) are loaded from Google's CDN. Google may log your IP address when serving these font files.

Beyond these two passive infrastructure services, no personal data is shared with any third party.

4. Your Rights

Because we do not collect personal data, there is generally no data to access, correct, or delete. If you believe we hold data about you (for example via Vercel infrastructure logs), you may contact us at privacy@ditherlab.pro and we will assist you to the extent possible.

If you are in Switzerland and believe your data rights have been infringed, you may lodge a complaint with the Federal Data Protection and Information Commissioner (edoeb.admin.ch). If you are in the EU/EEA, you may contact your local supervisory authority.

5. Changes to This Policy

We may update this policy as the Service evolves — for example if a paid tier or account system is introduced in the future. Material changes will be communicated on the DitherLab website and reflected in the "Last updated" date above.
