Contact

One address covers everything: hello@clevercat.cc. There is no contact form here because the site stores nothing and runs no server code, so a form would have nowhere to send your message.

What to write about

A tool gives a wrong result

This is the most useful message you can send. Include the values you entered, the result you saw, and the result you expected. If the tool has options, say which ones were on. Browser and device help when the problem is a display issue rather than a calculation.

Suggest a tool

Tell us the task, not just the title. A short description of what you do today — the spreadsheet, the site you use, the step that annoys you — makes it much easier to judge whether a page can be built that actually helps.

Translation and wording

The Spanish and Portuguese pages are checked, but regional wording varies. If a term reads oddly where you live, send the sentence and a better version.

Advertising, reuse and press

Advertising on the site is handled through Google AdSense; ask us for placement details. You are welcome to link to any page. To republish an explanation or use a screenshot, ask first and credit CleverCat.CC.

Response time

Messages are read within a few working days. Bug reports jump the queue; feature requests are collected and reviewed in batches when new tools are planned.
