Strange, the download from the app store (https://apps.apple.com/us/app/adguard-adblock-privacy/id1047...) is 100 MB, but my install somehow crept up to ~400 (logs, maybe?) over a couple of years of use. I don't have it installed any more, but it's wild how much this varies across devices. What phone do you use? I use a 2016 SE, I wonder if there's a bug that's consume extra space on a device as old (and likely untested by AdGuard) as mine?
