Write to us

ManyHand has one address for everything — problems, corrections, suggestions and privacy questions.

A tool is not working

The tools run in your browser, so what goes wrong usually depends on the device. To let us reproduce the problem, please include:

Which tool it was — the page address is enough.
What you did, what you expected and what happened instead.
Your device and browser, for example “Android phone, Chrome” or “Windows laptop, Firefox”.
A screenshot, if the problem is something you can see.

Please do not attach private documents. If a PDF or photo will not open in a tool, a description of the file — its size, where it came from, whether it is password-protected — is usually enough.

A result looks wrong

If a calculator, converter or reference page gives an answer you believe is incorrect, send the numbers you entered, the answer you got and the answer you expected. For the music tools, tell us the raga, tala or tuning and what sounded wrong.

Suggest a tool

Tell us the job you were trying to get done rather than the tool you imagined — “I need to put four ID photos on one sheet to print” is more useful than “add a collage maker”. The tools that fit here are ones that can run entirely in the browser without an account.

Privacy and data requests

ManyHand has no accounts and does not receive the content you put into a tool, so there is normally nothing stored about you for us to look up or erase. The privacy policy explains what the site does use — analytics and advertising from Google — and how to control it. If you still have a question about your data, write to the address above.

Coloring pages, schools and reuse

The coloring pages are free to print for home and classroom use, and teachers do not need to ask first. For anything else — reprinting them in a book, a product or another website — please write and ask. The terms of use have the details.

Before you write

A phone tool shows nothing. The compass, level, sound meter, GPS and flashlight need a permission that your browser asks for the first time. If you refused it, allow it for manyhand.com in the browser's site settings and reload the page.
Your saved work has gone. Tools that remember your entries keep them in the browser you used, on that device. They do not follow you to another browser or phone, and clearing site data removes them.
Speech to Text does nothing. It depends on speech recognition built into the browser. It works in Chrome and Edge and is missing from some other browsers.
