Privacy and data

These tools are built to work without an account and without sending what you type anywhere.

What runs locally

65 of the 67 tools run entirely in your browser. Your input is processed by JavaScript on the page and is never uploaded, logged or put in the URL. Closing the tab discards it. The catalog search is the one place where text goes into the address bar: your search words, so a search can be bookmarked or shared. Like any address, they can end up in your browser history.

Tools that use the network

Some information cannot be known inside the browser. These tools contact an external service, and the browser blocks any other connection through this site's Content Security Policy.

• What Is My IP

  Your browser asks ipify for your public IP address, then sends that IP to ipwho.is to look up its approximate location and provider.

  Contacts: api.ipify.org, api64.ipify.org, ipwho.is

• CEP Lookup

  Your browser sends the CEP you type to ViaCEP (viacep.com.br), a free public service, to look up its address.

  Contacts: viacep.com.br

Validation is not verification

Validators check the structure and check digits of a number. A valid result means the number is well formed, not that the document, card or account exists or belongs to anyone. Each tool page states which kind of check it performs.

What is stored on your device

Nothing here identifies you, and nothing is sent back to this site. Clearing your browser's site data removes all of it.

• Color theme. If you pick a theme, it is kept in one cookie named theme, shared with pedroivo.dev so both sites look the same, and copied to local storage. It is never set unless you change the theme, and it expires after a year.
• Recently used tools. The names of the last five tools you opened, kept in local storage so the search palette can list them first.
• Password generator options. Length and character sets, never the passwords themselves.
• Offline copies. Pages and scripts you visit are cached by your browser so the tools keep working without a connection. Only this site's own files are cached, never what you type.

What the server sees

The site is a set of static files served by Vercel. Like any web host, it receives the standard details of each request, such as your IP address, browser and the page requested. This site does not add anything to those requests. There are no analytics, trackers, ads or third-party scripts.
