iPhone Lockdown is the expert-backed, step-by-step guide that shuts it down in 30 minutes. 33 settings. Every one explained. No tech knowledge needed.
Instant PDF download + online reader. One-time purchase. No subscription.
Your iPhone is the most personal device you own. It knows where you sleep, who you talk to, what you search for at 2 AM, and where you were last Thursday. Most of this data is being shared with companies you've never heard of — not because Apple is careless, but because the default settings favor convenience over privacy. The good news: Apple built the tools to stop it. The bad news: they're buried across dozens of menus and most people never find them.
Plus 3 appendices: technical deep dives on how each protection actually works, real-world threat case studies (Pegasus, the UK encryption battle, location data brokers), and a companion Apple Shortcut that jumps you directly to every Settings page in the book.
Read the entire first chapter before you buy. No email required.
Time: about 4 minutes
Every app on your phone can ask to follow you around the internet — watching what you do in other apps, what websites you visit, and what you buy. Most people tap "Allow" without thinking. This chapter shuts that down.
Open: Settings → Privacy & Security → Tracking
Turn off "Allow Apps to Request to Track." OFF
That's it. One toggle.
What you just did
Every app that wants to track you across other apps and websites has to ask permission first. But app developers are good at designing those permission pop-ups to pressure you into saying yes.
By turning this off, the pop-up never appears. Instead, every app is automatically told "no." Behind the scenes, your phone gives each app a fake, blank tracking ID instead of your real one — so even if the app tries to track you anyway, it gets nothing useful.
This doesn't stop apps from working. It stops them from following you around after you close them.
For the technical details on how the IDFA tracking system works, see Appendix A.
Open: Settings → Privacy & Security → Apple Advertising
Turn off "Personalized Ads." OFF
What you just did
Apple runs its own small advertising network inside the App Store, Apple News, and Stocks. When Personalized Ads is on, Apple uses your purchase history, what you read, and your account information to decide which ads to show you.
Turning this off doesn't remove ads — you'll still see them in the App Store. But now they're based on what you're currently searching for, not a profile Apple has built about you over time.
Open: Settings → Privacy & Security → App Privacy Report
Turn on "App Privacy Report." ON
What you just did
Your phone will now keep a 7-day log of exactly which apps accessed your camera, microphone, location, and contacts — and which internet domains those apps contacted in the background.
You don't need to check this every day. But it's your evidence locker. If you ever wonder whether a flashlight app is secretly calling home to an advertising server in another country, this is where you'll find out.
Check it once a week. If an app is contacting domains labeled "Advertising" or "Analytics" that seem unrelated to what the app does, that's a signal to delete it.
Time spent: ~4 minutes
You just cut off the primary way apps track you across the internet. From this moment, your phone returns a blank ID to every app that asks to follow you. Apple's own ad profile on you is no longer being built. And your phone is now logging exactly what every app does behind your back.
Next up: your location data — which is even more personal than your browsing history.
Every Settings path is a link. Reading on iPhone? Tap it — it opens that exact Settings page. No hunting through menus.
