Who runs STSApps
STSApps.biz is operated by Savvy Tech Sphere, LLC, a small independent software studio. We build and run a collection of single-purpose web tools that handle one task each: converting a color, resizing an image, splitting a bill, building a campaign URL, running a focus timer. The site is part of the wider Savvy Tech Sphere portfolio, which also includes the games at sts.games.
There is no large team and no outside ownership. The same studio that designs the tools also writes the supporting guides, answers contact messages, and keeps the site running.
What the site is
STSApps is a set of free, browser-based utilities. Each tool is meant to do its job quickly and then get out of the way. You do not need an account to use them, and most tools run entirely in your browser, so the data you type in stays on your device unless a tool clearly needs to send something to complete its task.
Alongside the tools, the guides section explains the concepts behind them in plain language: how percentages work, what UTM parameters do, and how to split a shared bill fairly. The goal is to be useful before, during, and after you reach for a tool.
How the tools are built
Every tool is a focused web app built with the same component system, so inputs, results, and copy buttons behave consistently from one tool to the next. We favor quiet, organized layouts over heavy marketing, and we keep each tool light so it loads fast on a phone or a laptop.
We test the tools and their supporting content before they ship, and we keep them deployed and maintained rather than abandoning them after launch. When we change how a tool works, we update its on-page explanation to match.
How we handle your data
We keep data collection minimal. Tools that can run locally do, and we do not ask you to sign up to use them. For the full account of what is and is not collected, see the privacy policy and cookie preferences.
How our content is produced
The guides and tool explanations follow a documented set of editorial standards covering how content is written, reviewed, and corrected. You can read those standards on the editorial standards page.
