Don't have an answer but I'm genuinely surprised and impressed that the majority of responses aren't people being snarky about religion and instead, just folks trying to help you out!

Good luck!

Why not an epub reader? Is there some functionality these websites have that isn't just providing the text?

This one looks like what you might be looking for.

Edit: it's even on fdroid.

Edit: maybe The Life Or The Light.

Good luck on your search!

OliveTree. Excellent app for study. They have literally everything including devotional. It’s the power app for study.

F-droid has a couple.

If you use a debian or debian- derivated distribution, you can install it with apt install bible-kjv.

another option is to have an epub version of it that you can load into a reader. you should be able to add bookmarks etc. It might not be as feature-rich as an app, but if you want privacy, it's about as close to reading a book as you're going to get.

what version?

I think the trick is the daily devotional, they'll want to know who you are to deliver that.

Bible Gateway is great if you just want the text, multiple translations even.

Press tab a few times in TempleOS.

you version has no ads, not sure about tracking. does have decent devotionals and no account required

Does the Crossway ESV app do it? The issue with open source bible apps is that they rely on public domain translations, but Xiphos and AndBible are alright

This might be of interest but the UI looks bad

For android:

And found this insane open source OP one for multiple platforms https://github.com/eliranwong/UniqueBible

Yeah I was pretty disappointed the main app on iOS and Android has you create an account to download offline translations.

Like someone else said, I think getting an offline PDF copy would be a good substitute for this.

The BibleGateway and BibleHub websites have always been good for me and I never have to log in. But not sure about them keeping data for anyone visiting. You could visit in incognito to avoid that concern.

For your phone? On iOS, the most popular Bible app doesn't have ads.
