Questions and answers
Is it free?
Yes. All tools are free and work without sign-up, and there are no ads on the pages.
Where does my data go?
Text compare, the password generator and photo resizing run in your browser: texts, passwords and photos never leave your device. The translator sends the text to our translation server, and “My IP” and “IP geolocation” look the address up at ipinfo.io.
What are the partner tools?
The Russian production calendar, Bank of Russia exchange rates, the loan calculator and the invoice generator run on the website of our partner, the Kup2B B2B marketplace. They are free and need no sign-up either; the links open in a new tab.
Can I order a tool of my own?
Yes. We build websites, customer portals and internal services for businesses — including small tools like these for your task. Leave a request and we will estimate the work.
Need a custom service or work on your website?
We built these tools ourselves. We build websites, client dashboards, and internal business services the same way — and take over support of ones that are already running.
