This widget adds a <a href="http://www.subtome.com/" rel="nofollow ugc">SubToMe</a> button to your WordPress blog. This button allows your readers to follow your blog using their favorite applications.
If the user clicks the button, then, it will load an external iframe with JavaScript. The iframe will show the user the list of their favorite subscription tools. Once they pick one, they’re redirect to it with your blog information.
The user information is stored in the browser, but is only accessible on the domain <code>subtome.com</code>, which is why we have to load the iframe.
No data is ever “leaked”. The whole <a href="https://github.com/superfeedr/subtome" rel="nofollow ugc">SubToMe code</a> is open source. Feel free to check it out by yourself.
