Questions

Are the SEO for Solos tools really free?

All 7 SEO for Solos tools are free and require no account and no email address. They exist to be useful on their own, and the paid product is mentioned once at the bottom of each page.

Do the tools store what I enter?

The SEO for Solos tools run in the browser wherever possible and store nothing. The schema validator and the site auditor are the exceptions, because fetching a URL requires a server request; those requests are rate limited and the responses are not retained.
