The collection

Seven things, each finished

Four browser extensions, two offline games for kids, and a trilingual learning pack for families. Every one is done: tested, shipped, and small on purpose.



The deal

Why one-time, and why private

Most useful little tools are sold as a subscription you resent, or are free because you are the product. Neither sits right with us, so here is the trade we make instead.

  • Pay once, own it

    One purchase, then it is yours. No recurring fee, no renewal you forgot about, no premium tier holding your own work hostage. The price you see is the whole price, and a license covers up to three of your devices.

  • Your data stays with you

    Each tool asks for the fewest permissions it needs and does its work inside your browser. No analytics, no telemetry, no account to leak. The only call a paid extension ever makes is a license check to our own server, carrying your key and a random device id and nothing else. Your content never leaves your device.

  • Works in every Chromium browser

    The extensions install and behave the same in Chrome, Brave, Edge, Opera, Vivaldi and Arc. The two games are self-contained HTML5 that also run offline and install as an app.

Common questions

What is the Successful Store?

It is a small studio of seven finished products by MEGZO_tech: four browser extensions, two offline games for kids, and a trilingual learning pack for families. Each one does a single job well, costs a one-time price, and keeps your data on your own device.

Are these one-time purchases or subscriptions?

Nothing here is a subscription. The four extensions and the learning pack are one-time purchases you own forever, and the two kids’ games are free with an optional pay-what-you-want. There are no recurring fees, no renewals, and no premium tier that holds your own work hostage.

Do I need an account, and is my data tracked?

No account, no email wall, and no tracking. Each tool asks for the fewest permissions it needs and does its work on your device. There is no analytics and no telemetry. The single exception is a license check the paid extensions make to our own server: your key, a random device id, and nothing else.

Which browsers do the extensions work in?

The four extensions install and behave the same in Google Chrome, Brave, Microsoft Edge, Opera, Vivaldi, Arc, and any other Chromium browser. The two games are self-contained HTML5 that run offline and install as an app.

How do I install a product?

Open the product page and use its Get link to buy and install. Extensions install through your browser like any other extension. The games open in a browser tab and can be installed as an app on a desktop or tablet.

Everywhere you already are

Pick your browser. It works there.

Every extension installs and behaves the same in Google Chrome, Brave, Microsoft Edge, Opera, Vivaldi, Arc, and any other Chromium browser. The two Quest games are self-contained HTML5: they run offline and install as an app (PWA) on a desktop or a tablet.
