These independent organizations certify that "TheSage's English Dictionary and Thesaurus" is free of spyware, adware, viruses, trojans, and any other kind of malaware.



The development of TheSage demands substantial funding. We have carried this burden for many years and have kept TheSage free for personal and professional use. However, as the amount of time, resources, and effort required only continues to increase, user support has become essential.

Many high-quality applications have been discontinued, over time, due to lack of funding. Please don't let TheSage become abandonware.

If you find TheSage useful, please consider supporting its development with a donation through PayPal.

If you take a look at TheSage's changelog, you will see that most releases are private and only a few are made public. This policy will continue. However, from version 4.0 on, donors will be able to download private releases. It is our way of saying thank you very, very much.
