Terms of service

These terms cover buying and using Extension Engine extensions, including the free trial. Buyers accept them with the checkbox at checkout.

Effective date: November 10, 2026

Who sells the extensions

Extension Engine extensions are sold by Phillip Chambers, a sole proprietor. Contact:support@extension-engine.com.

Postal address for legal notices: 3769 Sierra Drive, Merritt Island, FL 32953.

Who can buy

You must be 18 or older to buy. This site is not directed to children under 13.

What you buy

  • Each extension is sold separately, as a one-time payment. The price is shown on the extension's page.
  • Payment is handled by Stripe.
  • A purchase covers that extension only.
  • Extensions are downloaded as a ZIP file from GitHub and loaded into Chrome. See the install guide.

Your license

  • A purchase lets you use that extension for your personal use and in your own work.
  • You may not resell or redistribute it.

A purchase works on up to 3 devices at a time. Signing in on a fourth device signs out the one used least recently.

What "lifetime access" means

Lifetime access means the lifetime of the product. Your access continues as long as the product remains available and your purchase is paid and not revoked (for example, by a payment dispute).

Free trial

  • Each extension includes 3 free downloads per email address. The trial requires signing in with your email.
  • A free download counts when it starts, even if it later fails.
  • When your free downloads are used up, you need to buy the extension to keep downloading.

No refunds

All sales are final. No refunds.

Every buyer, including buyers in the EU and UK, accepts these terms at checkout. By accepting them, you acknowledge that your access begins immediately and that you give up any right to cancel or withdraw from your purchase. See the refund policy.

Acceptable use

  • Use the extensions only with content your own browser session can already load. They are not made to bypass DRM, encryption, logins, paywalls, or CAPTCHAs, and you may not use them to try.
  • You are responsible for respecting the rights of the people who made the content and the terms of the platforms you use.
  • Extension Engine is not affiliated with, endorsed by, or sponsored by the platforms its extensions work with.

Disputed payments

If you dispute a payment with your bank or card issuer, access from that purchase is revoked. If the dispute is closed in our favor, access is restored.

Changes to third-party sites

Extensions work with websites we do not control. Changes to those sites can break an extension until an updated version ships.

Updates are provided at the seller's discretion.

Privacy

See the privacy policy for what data is collected and why.

Disclaimer and limitation of liability

The extensions and this website are provided "as is" and "as available". We do not promise that an extension will work on every page, that it will keep working after a third-party site changes, or that it will be free of errors.

As far as the law allows, we are not liable for indirect or consequential losses, such as lost profits, lost data or lost time. As far as the law allows, our total liability to you for any claim about an extension is limited to the amount you paid for that extension.

Some places do not allow these limits. Where that is the case, they apply only as far as the law there allows. Nothing in these terms limits any liability that the law does not allow to be limited.

Governing law and disputes

These terms are governed by the laws of the State of Florida, USA.

If you have a problem with a purchase or an extension, please emailsupport@extension-engine.com first, so we can try to resolve it.

If you live outside the United States, choosing Florida law does not take away any protection that the mandatory laws of your country give you.

Any dispute that goes to court will be heard in the state courts in Brevard County, Florida, or the federal courts for the Middle District of Florida.

Changes to these terms

Changes to these terms are posted on this site with a new effective date.
