I'll second this. I would like to give this a try (been job hunting for the past 6 months), but I'm also a bit paranoid in sharing a lot of data, especially with a service that has no privacy policy.
Very fair point! Not to put the onus on you but do you happen to have any pointers on where I can get started? As it stands, I am using google analytics, and also storing the resume text (though not the document), and the embedding of the text. I hope at the very least that provides some transparency.
Using Google Analytics might have some GDPR implications in Europe. A more GDPR-friendly alternative might be Plausible Analytics.
Also, given the amount of information contained in a CV, even without a name, address, contact info etc, it could make the process of identifying the actual person fairly easy, thus it might have some GDPR implications.
You could have a look at some Privacy Policies from recruiting agencies [0][1], though those are (in my opinion) fairly "abusive".
my 2 cents: given this is a side project, I would not store any data at all
