Extension Engine

Privacy policy

The extensions run inside your logged-in browser sessions, so we collect as little as we can. This page lists what is collected, why, and what never is.

Effective date: November 10, 2026

Who is responsible for your data

Phillip Chambers, a sole proprietor, who sells Extension Engine extensions. Contact:[email protected]. Postal address for legal notices: 3769 Sierra Drive, Merritt Island, FL 32953.

What the extensions send, and why

The only data an extension sends off your computer is:

  • Your email address, to sign you in and to link your free downloads and purchases to you.
  • The sign-in code we email you, to confirm the address is yours.
  • A sign-in token, to keep you signed in.
  • An install ID, a random ID for each install, used to enforce the limit of 3 devices at a time.
  • A product ID, which says which extension a download is for.
  • Your marketing email choice, if you opt in.

What our server stores

  • Your email address and your marketing email choice.
  • How many free downloads you have used for each extension.
  • Your install IDs for each extension, and when each was last used (up to 3; signing in on a fourth device replaces the one used least recently).
  • A record of each purchase: which extension, when, the Stripe checkout and payment IDs, and whether the purchase was revoked because of a payment dispute.

Our server does not store your card details. Payment is handled by Stripe.

What is never collected

  • The addresses (URLs) or titles of pages you visit.
  • Video addresses.
  • What you download, or anything about it. Files are built and saved on your own computer.
  • Your browsing history.

The extensions never track you or collect analytics.

What Cloudflare collects

Cloudflare hosts this website. To deliver a page to you, it receives the technical details your browser sends with every request, such as your IP address and browser type. Cloudflare Web Analytics, which does not use cookies, gives us statistics about visits to the site. Cloudflare decides how long it keeps this information under its own privacy policy; please read that policy for details.

What is stored on your computer

  • Download progress and an in-progress sign-in, kept for the current browser session and cleared when the browser closes.
  • Your sign-in session and install ID, kept in the extension's local storage so you stay signed in after restarting the browser.

Services that handle your data

  • Stripe: payments.
  • Supabase: sign-in, purchase records, and free-trial records, stored in Oregon, USA.
  • Resend: sign-in emails and marketing emails.
  • Cloudflare: website hosting, website analytics, and support email forwarding.
  • Google: Gmail, where forwarded support email is delivered.
  • GitHub: extension downloads.

Where data is stored

  • Our sign-in, purchase and free-trial records are stored with Supabase in Oregon, USA.
  • Stripe, Resend, Cloudflare, Google and GitHub may process data in the United States and in other countries. Each one explains where and how it handles data in its own privacy policy.
  • The seller is based in Florida, USA.

Marketing emails

We send marketing emails only if you opt in. Not opting in does not affect your free downloads or purchases.

To unsubscribe, use the unsubscribe link included in every marketing email, or email[email protected].

How long data is kept

  • While you have an account, we keep your email address, your marketing email choice, your free-download counts, your install IDs and your purchase records.
  • We keep at most 3 install IDs per extension. Signing in on a fourth device replaces the one used least recently.
  • What the extension keeps for the current browser session is cleared when the browser closes.
  • After you ask us to delete your account, we keep your purchase records and the email address they belong to, for dispute and tax purposes, for as long as we need them for those purposes. This includes a purchase revoked by a payment dispute. Everything else is deleted.

Your requests

To ask about your data, or to ask us to correct or delete it, email[email protected].

We verify a request by asking you to reply from your account's email address. We answer requests within 30 days.

Deleting your account

When you ask us to delete your account, we delete your free-download counts, your install IDs and your marketing email choice, and we stop sending you marketing emails. If you have bought an extension, we keep your purchase records and the email address they belong to, for dispute and tax purposes. If you have not bought anything, your email address is deleted too.

Deleting your account with us does not delete records that Stripe and the other services listed above keep under their own policies.

Your data-protection rights

Depending on where you live, you may have the right to ask for a copy of your data, to have it corrected or deleted, to object to or limit how it is used, and to receive it in a format you can take elsewhere. You may also have the right to complain to the data-protection authority where you live. To use any of these rights, email[email protected].
