Contact XCODX

Questions about the editor or the compilers, a bug to report, a correction for one of our articles, or a privacy request? Email [email protected]. We read every message and aim to reply within 5 business days.

01 Email us

All messages go to one inbox: [email protected]. Using the subject line for your topic helps us reply faster; select a subject to open a new email with it filled in.

Please do not email passwords, API keys or other secrets, and only send code you are comfortable sharing. XCODX never asks for your password or payment details.

02 Reporting a bug

A good bug report helps us reproduce and fix the problem quickly. Please include:

  • The page or tool you were using (for example /editor, /compiler/python or /build/react)
  • Your browser and version, and your operating system or device
  • What you did, what you expected to happen and what happened instead
  • The framework and the file that fails, plus a small piece of code that reproduces the problem if you can share one
  • Any console message or error output, or a screenshot

The Help Center and the documentation answer many common questions.

03 Corrections to our articles

We want our blog posts, guides and compiler pages to be accurate. If you find a mistake, an outdated comparison or a code sample that does not run, email us with the page address and the change you suggest. We review every correction and update the page.

04 Privacy and data requests

XCODX has no accounts, and your projects are stored in your own browser, so we hold very little personal data about you. Questions about analytics or advertising cookies, or requests under the GDPR, UK GDPR or US state privacy laws, can be sent to [email protected]. Our Privacy Policy and Cookie Policy explain what is collected and how to opt out.

05 Reporting an ad

Ads on XCODX are provided by Google AdSense. If you see an ad that seems misleading, offensive or inappropriate, use the “AdChoices” or “Why this ad?” control on the ad to report it directly to Google. You can also email us the page address and a description or screenshot of the ad, and we will review it and block the advertiser where possible.

06 Before you write

  • Lost work: projects are saved only in your own browser. We cannot see or recover them, so please export important projects regularly.
  • Commercial use: the code you write with XCODX is yours. See our Terms of Service for details.
  • About us: learn who builds XCODX and how it is funded on the About page.
