7 iPhone Privacy Settings Worth Changing Today

You can tighten your iPhone privacy settings in about ten minutes, no technical background needed. The seven changes below all live in the Settings app. Each closes a specific gap — a borrowed phone, a stolen phone, an app that collects more than it needs — and none of them slows your phone down or breaks the apps you rely on.

Quick summary

Three of these settings protect you from people who get hold of your phone: the Hidden album lock, Stolen Device Protection, and app locking. The other four limit what apps and email senders quietly collect — location, cross-app tracking, lock screen previews, and mail activity. Each works on its own, so start wherever it matches how you use your phone.

The list

1. Lock the Hidden album — then hide it entirely

Since iOS 16, the Hidden album is locked by default and opens only with Face ID or Touch ID. Go one step further: in Settings > Apps > Photos, turn off Show Hidden Album and the album disappears from Photos entirely. Two honest caveats. Hiding isn't encryption, and if iCloud Photos is on, hidden photos still sync to every device on your Apple Account. We've covered what the Hidden album really protects in more depth.

2. Turn on Stolen Device Protection

Someone who steals your phone after watching you type your passcode can normally reset your Apple Account password and lock you out. Stolen Device Protection (iOS 17.3 and later) stops that. Away from familiar places, sensitive actions require Face ID or Touch ID with no passcode fallback, and critical changes sit behind a one-hour security delay. Turn it on in Settings > Face ID & Passcode — and pick "Always" under Require Security Delay if you want the same rules everywhere. It pairs well with a plan for protecting your photos if your iPhone is stolen.

3. Lock or hide individual apps behind Face ID

Touch and hold any app icon and choose Require Face ID. The app now opens only for you, and its content disappears from search, Siri suggestions, and notification previews. Choose "Hide and Require Face ID" instead and the app moves into a locked Hidden folder in the App Library. It's the quickest fix when you lend your phone for a call — the same idea behind locking photos with Face ID.

4. Audit location access — and Significant Locations

In Settings > Privacy & Security > Location Services, every app gets one of four levels — Never, Ask Next Time, While Using, or Always — plus a Precise Location toggle. Most apps work fine with While Using and an approximate location. Then scroll to System Services > Significant Locations & Routes: your phone keeps a list of the places you visit most. Review it, but note that Stolen Device Protection uses it to recognize familiar locations, so weigh that before switching it off.

5. Stop apps from tracking you across apps

In Settings > Privacy & Security > Tracking, turn off Allow Apps to Request to Track. This disables the advertising identifier that, as the EFF's settings guide explains, enables most third-party tracking on mobile devices. Apps simply lose the ability to ask.

6. Hide notification previews on the lock screen

By default, anyone near your phone can read incoming messages on the lock screen. In Settings > Notifications > Show Previews, choose When Unlocked — previews appear only once Face ID recognizes you — or Never.

7. Turn on Mail Privacy Protection

In Settings > Apps > Mail > Privacy Protection, turn on Protect Mail Activity. Senders can no longer see your IP address or whether you opened their email. While you're there, set Safari's Advanced Tracking and Fingerprinting Protection to All Browsing under Settings > Apps > Safari > Advanced.

Putting this into practice with Privara

These seven settings reduce what apps, advertisers, and people around you can see. What they don't do is encrypt your private files — hiding an album or locking an app changes who can look, not how the data is stored.

That's the gap Privara closes, and it's the best way to keep the content in this article private. One AES-256-encrypted vault holds your photos, videos, documents, and contacts, encrypted at rest rather than tucked out of sight. The app looks and works exactly like a calculator; the vault opens only when you enter your PIN. There's no account to create and nothing is uploaded by default — a local, zero-knowledge vault. You can layer Face ID on top of your PIN, and a decoy PIN opens a separate vault.

Spend ten minutes on the settings above, then get Privara on the App Store and move what matters most into the vault.

Frequently asked questions

Do I need to change all seven settings?

No — each stands alone. Start with the two that help most if your phone is lost or borrowed: Stolen Device Protection and the Hidden album lock.

Will these settings slow down my iPhone or break apps?

No. They change what apps and people can see, not how the phone performs. If an app loses a feature you need after you revoke a permission, you can reverse the change in Settings at any time.

Is the Hidden album enough to keep photos private?

It stops casual browsing, but it hides rather than encrypts, and hidden photos still sync through iCloud Photos. For content that must stay private, an encrypted vault app like Privara protects at the storage level.

What does Stolen Device Protection actually prevent?

It stops a thief who knows your passcode from changing your Apple Account password, using saved passwords, or erasing the phone — by requiring Face ID or Touch ID with no passcode fallback, plus a one-hour delay away from familiar locations.
