> Reach the maintainer of CheckWhenDone by email at olli@ollidev.com.

CheckWhenDone is built and run by OlliDev, an independent software
developer. The best way to get in touch is email:

- Email: [olli@ollidev.com](mailto:olli@ollidev.com)

Email is read personally and answered as time allows, usually within a few
days. Useful things to write in about include bug reports (a sheet that
prints wrong, a link that does not restore a configuration), feature
suggestions, and questions about how the sheets or the sharing links work.

When reporting a problem with a specific sheet, include the full sheet URL.
The whole configuration lives in the URL, so the link alone reproduces
exactly what you were seeing. There is no account system and no support
portal; email is the single channel, and it goes straight to the person who
wrote the code.
