About
Practical everyday tools in one site. No signup and no installation.
The project
Here I gather calculators, converters, generators, and SEO utilities I built for work and personal use. The idea is to have everything in one place, ready to open and use.
Each tool runs in the browser. In most cases, what you type never leaves your device.
Privacy
By default, nothing you type or generate here is sent to a server. Processing happens locally on your device.
Some tools call external APIs when needed — for example, the investment calculator fetches rates from Brazil's central bank and SEO tools fetch public metadata from URLs. In those cases, only the data strictly required for the request is transmitted.

Who I am
Cicero Valentim
Software developer focused on web products and useful everyday experiences.
This site brings together tools I use myself or wish I had at hand — calculators, converters, playgrounds, and SEO utilities.
I maintain the project independently and evolve it as new ideas come up.
