You can test MacPaw’s software risk-free before committing to purchasing a lifetime license, since Gemini is available as a free download. Using the software doesn't require any credit card details but is limited to testing the features the software provides, as well as restricting you to the deletion of only 500MB of duplicate data. If you are satisfied with the results, you can then benefit from any of the offers and purchase a license.
