Privacy policy
Last updated: 14 November 2026
This policy covers microbench.app and every tool published under it, such as frete.microbench.app. It says what we collect, why, and how to have it deleted.
Who is responsible
Microbench is a product of DNS Tech Solutions Ltda, a company based in Brazil, which is the controller of the data described here. For any privacy request, write to contact@microbench.app. The same address reaches the person in charge of data protection.
What we collect
| Data | When | Why |
|---|---|---|
| E-mail address, and, if you give them, company name, number of routes and whether you are interested in the paid plan | When you fill in a sign-up form on a tool | To send the alerts you asked for and to tell you when the paid plan opens |
| Anonymous daily totals: page visits, calculations made, sign-ups, and whether a visit came from an advertisement | When you use a page | To learn whether a tool is useful. These are counters only. They hold no IP address, no identifier and nothing that points to a person |
| Whatever you write to us | When you send us an e-mail | To answer you |
Figures you type into a calculator, and freight tables you paste into the table check, are processed in your browser and are not sent to us.
Calls to the free API send only the parameters in the address. We do not store them; we only count how many calls were made in a day.
Cookies and browser storage
Our pages set no cookies and load no tracking or advertising scripts, with one exception: the confirmation page shown after you sign up for the freight tool loads the Google Ads tag, which may set Google cookies so we can count sign-ups that came from our ads. The home page saves your choice of dark or light theme in your own browser (local storage). It never leaves your device.
Legal basis
Under Brazil's data protection law (LGPD, Law 13.709/2018), we process sign-up data with your consent, given when you submit the form, and anonymous totals and messages you send us under our legitimate interest in running and improving the service. Where the GDPR applies, the bases are the same.
Who else handles the data
- Cloudflare, Inc. hosts our pages, database and incoming mail. Like any host, it processes your IP address and browser details to deliver the page and to protect it from abuse. Its servers may be outside Brazil.
- Google Fonts serves the typefaces on microbench.app. Your browser fetches them from Google, which receives your IP address. The freight tool does not use them.
- Google Ads receives, through its tag on the sign-up confirmation page, your IP address, browser details and the ad click identifier, to measure which ads led to a sign-up. It does not receive your e-mail.
- The mail provider that forwards messages sent to our addresses to our inbox.
We do not sell personal data and do not share it with anyone else, unless a law or a court order requires it.
How long we keep it
- Sign-up data: until you ask to leave the list. If a tool is discontinued, its sign-up list is deleted within 90 days.
- Messages you send us: for as long as needed to answer and to keep a record of what was agreed.
- Anonymous totals: indefinitely, since they identify no one.
Your rights
You may ask us at any time to confirm whether we hold data about you, to see it, correct it, delete it, receive a copy, or to withdraw your consent. Write to contact@microbench.app from the address in question, or reply to any message we sent you. We answer within 15 days. You may also complain to Brazil's data protection authority (ANPD) or to the authority of your country.
Security
All pages are served over an encrypted connection, and access to the database is restricted to the people who operate the service. No system is perfectly secure; if an incident affects your data, we will tell you and the authority as the law requires.
Children
Our tools are made for businesses and are not directed at anyone under 18.
Changes
If this policy changes, the new text and its date appear on this page. If a change affects how we use data you already gave us, we will write to you first.
