Frequently Asked Questions
Does the password generator save or transmit generated passwords?
No. Passwords are generated directly inside your browser and are never sent to or stored on any server.
Does the JSON formatter send my data to a server?
No. Formatting, validation, and minification occur locally in your browser without transmitting any content externally.
Does the countdown timer update automatically?
Yes, every second, without needing to refresh the page. It also automatically switches to "time since" when the target date has passed.
Does the holidays page account for movable holidays like Carnival and Easter?
Yes. These movable holidays are calculated dynamically based on the Easter date for that year, rather than using hardcoded static dates.
Does the time zone calculator account for Daylight Saving Time (DST)?
Yes, automatically, using your browser's internal time zone database, which adjusts based on the selected date.
Do the generated CPFs and CNPJs belong to real people or businesses?
No. They are generated randomly following mathematical check-digit rules exclusively for software testing and development purposes.
Does the validator verify if a CPF or CNPJ actually exists?
No, it only verifies mathematical (syntactic) validity based on check digits. Confirming actual existence requires querying official government databases.
