Questions should be easier to answer than to hide.
How the apps work, what they store, where the other domains fit, and where the limits are.
01Are the tools really free?+
The Site Check-up, contractor calculators, and Etsy Fee Calculator are free to use without creating an account. A product page states clearly when an optional service or paid component is separate.
02What data do the apps store?+
Most calculators run entirely in your browser. The Site Check-up sends the public URL you enter to the same-origin audit service so it can run the job. Contact details are collected only when you choose to submit them. The privacy page documents the current behavior.
03Can I embed these on my site?+
Some tools have an embeddable version and others are designed to stay on this site. The Widgets page identifies what can be embedded and what requires VertaFlow or a custom implementation.
04Who builds and maintains them?+
Anthony Jones designs, builds, tests, and maintains this product division from Rome, New York. The source decisions and implementation lessons are documented in the Build Notes.
05Why does this site exist separately from designedbyanthony.com?+
The domains have different jobs. designedbyanthony.online owns apps, calculators, widgets, and technical build notes. designedbyanthony.com owns custom websites, Local Visibility, studio pricing, and service-business content.
06How is VertaFlow related?+
VertaFlow is the flagship CRM product built by the same operator. Some apps use a same-origin route into VertaFlow infrastructure when they need an audit job, lead capture, or another server-side action. CRM features, pricing, and documentation remain canonical on vertaflow.io.
07Do the calculators replace a professional estimate?+
No. They provide planning estimates from the measurements and assumptions you enter. Field conditions, local codes, supplier packaging, labor practices, and product specifications can change the real order or quote.
08How are calculations tested?+
Calculator logic is kept in typed functions with automated tests for normal inputs and important boundaries. Each page also explains its units, assumptions, waste factor, and rounding so the visible method can be checked against the implementation.
09Why are some apps static while others call an API?+
A browser can calculate materials or fees locally. A website check-up needs to inspect another public URL and therefore requires server-side work. The architecture keeps static pages and browser calculations local, then uses a same-origin Worker route only when the action genuinely needs it.
10Can I request a new calculator or small app?+
Yes. Use the contact page and describe the repeated task, the inputs you have, and the result you need. A focused tool with a clear method is a better candidate than a broad platform idea.
11Can I use the calculations commercially?+
You may use the displayed results in your own planning and estimates, but you remain responsible for verifying measurements, prices, codes, and supplier requirements. The site does not provide engineering, legal, tax, or financial advice.
12Where can I read the implementation decisions?+
The Build Notes document architecture, deployment, performance, accessibility, technical SEO, and product decisions. They are written from the current implementation and link to primary documentation when an outside technical claim matters.
