Terms of use

Last updated: 13 November 2026

These terms cover microbench.app and every tool published under it, such as frete.microbench.app. By using a page or a tool, you agree to them. If you do not agree, please do not use the service.

Who we are

Microbench is a product of DNS Tech Solutions Ltda, a company based in Brazil. Contact: contact@microbench.app.

What the tools are

Each tool does one job for a business, such as a calculation or a check. The tools give information to help you decide. They are not legal, tax or accounting advice, and they do not replace the official rule or a professional who knows your case.

Official sources come first

Microbench is independent and has no link to any government body, including ANTT. When a tool repeats a number from an official table, we take care to match it and we show the source and its date on the page. Tables change, and we may be late or wrong. If a result differs from the official source, the official source is the one that counts. Check any figure that matters before you sign, quote or pay.

Free tools and the free API

Free tools and the free API are offered as they are, with no promise that they will always be available, fast or free of error. You may use the API in your own systems, including commercial ones, at a reasonable rate. We may limit or block use that overloads the service, and we may change or end the API.

Sign-up lists and paid plans

Joining a list is free and creates no obligation to buy. While a tool is in pre-launch, no payment is taken, and the price shown is the price we intend to charge, not an offer you can accept yet. When a paid plan opens, its price, what it includes and how to cancel will be shown before you pay, and those conditions will apply to the plan.

Fair use

Do not try to break, overload or get around the security of the service, sign up other people without their consent, or use the service for anything unlawful.

Our content

The name Microbench, the pages, their text, design and code belong to DNS Tech Solutions Ltda. The official tables and rules that the tools refer to are public and belong to no one. The results a tool gives you are yours to use.

Liability

To the extent the law allows, we are not liable for losses that follow from relying on a result, including fines, lost income or decisions made from it, nor for the service being unavailable. Nothing here removes rights that the law does not let us limit, including consumer rights where they apply.

Privacy

How we handle personal data is described in the privacy policy.

Changes

We may change these terms. The new text and its date appear on this page and apply from then on.

Law and courts

These terms follow the laws of Brazil. Disputes are settled in the courts of Goiânia, Goiás, Brazil, except where the law gives you the right to use the courts of your own home, as it does for consumers.
