Site privacy
Short version: this website does not track you.
This website
raavi.in is a static site. It sets no cookies, runs no analytics, and loads no advertising or tracking scripts. The site loads typefaces from Google Fonts, so your browser requests font files from Google's servers; see Google's own policy for how it handles those requests. The site is hosted on GitHub Pages, which may keep standard server logs under its own policy.
The Bible Study app
The Android app has its own, separate policy. In brief, it collects nothing and keeps all of your data on your device.
