Hi! I answered this in a few comments but:

The app performs its functions entirely client-side except for the job search to JSearch, which only requires the company name.

> What you choose to upload to JobsByReferral.com is entirely up to you - you don't need to upload the entire ZIP. You can upload the Connections.csv-formatted file after you review it. You could also obfuscate person names if you'd like, before uploading.

> We also do nothing with your data. You can verify the app does not send your data to any backend endpoints _except_ for company name (so that we can find jobs at that company).

Edit: we've added some privacy details here: https://jobsbyreferral.com/privacy
