When you're using devices that are always connected to the internet, it's difficult to completely protect your privacy. Luckily, there are plenty of great privacy hacks for your iPhone, which you can use to make it harder for trackers and spies to collect your data and snoop on your business. From built-in solutions, like adjusting app permissions, to purchasing privacy screen protectors, here are 10 hacks every iPhone user should consider to protect their privacy.
Get yourself a privacy screen protector
No software privacy hack can protect you from people looking over your shoulder to memorize your password, or from peeking to see what you're up to. What can protect you, however, is a privacy screen protector. I saw this first-hand: One of my friends recently tried to show me something on her iPhone, and I realized that I couldn't see anything at all until her phone was directly in front of me.
These screen protectors can make it easier to use your phone in public spaces without worrying about who's looking at its screen. That said, there are a few potential dealbreakers. These screen protectors are rather plasticky, and don't feel as nice or smooth as your iPhone's touchscreen. These products also lower your screen's brightness. I don't mind, but it can be a problem if you're trying to use your phone in bright lighting. If you can live with these cons though, this is a cheap privacy hack that's definitely worth considering.
Stop Apple from collecting your data (as much as you can)
Apple is known for its privacy policies, but in recent years, its resolve seems to be weakening a bit. The company is pushing ads into its apps and your notifications, and it's aggressively encouraging iPhone users to subscribe to Apple services. There's not much you can do to block promotional materials coming from the company directly, but it's still worth changing a few settings to limit Apple's own ads. This includes reducing Apple's data collection, too. Many of these options are available under Settings > Privacy & Security on your iPhone. On that page, you can navigate to these pages to disable quite a bit of tracking:
Carefully reviewing all options on these pages and disabling unnecessary features goes a long way in limiting Apple's data collection.
Deny (or limit) app permissions whenever you can
I used to allow all permissions an app requested when I first opened it. Over time, I realized that this led to a lot of notification spam, unnecessary data collection, and significant battery drain if the app was tracking my location. That's why I developed a new strategy: deny all permissions unless an app absolutely needs it. In general, I almost always deny permissions for the following: notifications, access to contacts, location, camera, microphone, and photos.
Newer versions of iOS allow you to share just a few contacts or photos, and even restrict GPS access to an approximate location instead of a precise marker. All of these are available under Settings > Privacy & Security in case you missed them while setting up an app.
Consider deleting apps known to track you
While the App Tracking Transparency option on your iPhone does reduce data collection from many apps, it's far from foolproof. In general, apps have access to far more data than their web versions, so try switching from apps to mobile websites wherever possible. If you delete apps such as Instagram, Facebook, or TikTok, and switch to logging in via Safari, you'll give away much less data, and some of the data you would otherwise give to the web apps will be blocked or spiked by Safari's privacy features, further protecting your data. As an added bonus, since web apps are generally a worse experience than dedicated apps, you're also far less likely to fall into a doomscrolling trap. I've used this fairly effectively with social media apps, but you can't always delete apps, like WhatsApp.
Install an adblocker (or use a better DNS)
Installing an ad blocker and a DNS app can do wonders for your iPhone privacy. Ad blockers such as uBlock Origin are good at blocking invasive tracking on your iPhone, but their effect is limited to Safari. To enhance the privacy of your internet traffic, you should consider installing an encrypted DNS app such as NextDNS, AdGuard DNS, or ControlD. All of these will block ads or trackers in most apps on your iPhone and safeguard you from some types of online security threats as well.
Use a VPN to hide your IP address
A good VPN protects your web browsing by routing your traffic through an encrypted network, in the process hiding your device's IP address. As such, it's much easier to surf the web anonymously, and much harder for websites and internet service providers to track your activity.
While VPNs can be a great privacy and security tool, exercise caution when using them. If the company behind the VPN is legitimate, your data isn't being tracked, but if it's not, then the VPN company could be logging all your data and selling it to advertisers or data brokers. While there are a few trusted free VPN providers, I always recommend going with a paid VPN for maximum privacy. Mullvad VPN is among the best paid VPNs out there and it allows you to create an account without even using an email address. You can also pay the 5 euros ($5.80) monthly fee using anonymous payment methods like cash, which makes Mullvad one of the best VPNs for privacy and anonymity.
If you're subscribed to Apple's iCloud plans, you should also consider enabling iCloud Private Relay to add a layer of privacy to your activity on Safari. iCloud Private Relay doesn't work with traffic from any other app, which makes it less useful than a VPN app, but if you only want to reduce browser data tracking from advertisers and your internet provider, it's good enough.
Safety Check is a must-have
Everyone should be using Safety Check on iPhone. This feature immediately lets you identify who you're sharing what with, including passwords, fitness activity, your current location, calendars, notes, and other data. To check on it, head to Settings > Privacy & Security > Safety Check > Manage Sharing & Access. You can go through the prompts to review app permissions, and set up an emergency contact, which ensures that your data (and you) are safe. While you can manually access all these options in the Settings app, the Safety Check prompt lets you find all features without combing through multiple pages, which will save you a lot of time.
Use Hide My Email to protect your email address
Whenever you sign in to a website, you end up sharing your real email address. If the site is hacked, your email is exposed, and can be targeted by hackers. To protect your email address, use an alias with each site. That way, if one website is compromised, you can simply disable that alias or be wary of phishing attempts targeted at just the one alias.
There are many ways to generate an email alias, but few are as easy as using Apple's Hide My Email feature. This feature is available to anyone who's paying for iCloud. On your iPhone, head over to Settings > [YOUR NAME] > iCloud > Hide My Email to create a new alias. When you're creating an account on various websites or apps, you'll also see a prompt to use Hide My Email above the keyboard, letting you generate an email alias with a single tap.
A password manager is a great privacy tool
A good password manager is also a must. Free password managers, such as the built-in Passwords app or BitWarden allow you to create unique, strong passwords for each website, which makes it far less likely a single hacker could compromise your accounts. You can also use these apps to store your two-factor authentication codes for an extra layer of security.
Even better, these apps can manage passkeys to help you log in to your online accounts. Passkeys eliminate the need to remember passwords, and are far more resistant to phishing attacks that could compromise your accounts. For more information on passkeys, check out our full guide here.
Encrypt your backups to protect your data from hacking
Having a backup of any important data is essential, but how you back up that data matters, too. As such, those backups should be encrypted whenever possible. This includes your iCloud Backup, and backups of your messaging apps such as Telegram or WhatsApp. Encryption makes it far less likely for an unauthorized party to read what's on your iPhone, as the data is totally scrambled without the key—which, in this case, is either your password or PIN. However, this is also where the danger lies. If you forget your backup password, even you won't be able to access the backup to restore data if you need to. Again, use a password manager to store these passwords so you'll never be able to forget.
Back up your data outside of the cloud for extra security
You should always have at least two backups of your data. If iCloud is down, or if Apple decides to lock you out of your account for any reason, there's nothing you can do to recover anything stored on the company's servers. However, having an encrypted offline backup of your data allows you to access it even when you don't have a working internet connection. You will need a laptop or a desktop computer running Windows or macOS for this step.
You can connect your iPhone to your Mac and open Finder to get started with the backup. Select your iPhone from the left pane, and select Back up all the data on your iPhone to this Mac from the right pane. Be sure to check Encrypt local backup, add a password, and save that password to a good password manager. Again, if you lose this password, you won't be able to access the backup at all. On Windows, you can download iTunes and follow the same steps, or use the built-in Apple Devices app instead.
Remove identifying information from social media photos
This isn't necessarily an iPhone privacy tip as much as it is a general privacy hack, but it's worth mentioning. These days, trackers and hackers effectively use social media posts, photos, and videos to profile you. While there are plenty of steps you can take to limit the data you share on social media, you might not know you can remove identifying data from photos you post online. "Exif" data includes a host of stats about the hardware that took the image, including your camera make and model, shutter speed, focal length, and, perhaps most importantly, location. You don't have to avoid sharing photos to protect this data, however: just remove the exif data before posting.
Use encrypted messaging apps to protect your conversations
For private messaging on your iPhone, you only want to use apps that offer end-to-end encryption, which means that only you and the intended recipient can read your messages. Some of the most popular messaging apps with end-to-end encryption include WhatsApp and Signal, though Apple's iMessage protocol is also encrypted end-to-end. That said, if you aren't texting an iPhone in the Messages app, your messages won't be encrypted, as both SMS and RCS are not encrypted protocols on iPhone at this time. That's changing soon, at least for RCS: Apple is adding support for RCS encryption with iOS 26.4, which means that your text messages will also be encrypted once the update is available.
Use Guided Access to prevent people from snooping through your iPhone
When you're letting someone else use your iPhone for a bit, you should enable Guided Access to prevent them from snooping. Guided Access prevents users from leaving the app you currently have on screen, so if you let someone use the Google app on your phone, they won't be able to go through your messages or photos instead. Go to Settings > Accessibility > Guided Access and enable the feature. You can use a passcode or Face ID to toggle a Guided Access session.
The next time you're handing over your iPhone to someone, open the app they need to access, then press the side button thrice in quick succession to enable Guided Access. From here, you can disable touch inputs in parts of the screen, set a time limit for the other person to use your phone, and disable the keyboard, among other options. Once you've set it all up, feel free to hand over your phone. You can disable Guided Access by entering the passcode or using Face ID. If you only have a few apps you want to keep out of others' hands, you can always choose to lock them individually behind a Face ID scan.
Use Lockdown Mode to prevent extreme attacks on your iPhone
Most people are never going to need to use Lockdown Mode, because it's designed to protect your data when it's under attack from government surveillance or from espionage. That said, it's still worth knowing about this tool in case you ever face a cyberattack or if you suspect that your iPhone has been infected with spyware. Lockdown Mode disables message attachments, links and link previews, most incoming FaceTime calls, many Apple services, certain web technologies and fonts in Safari, and many other features, that bad actors can use to obtain your private data.
I repeat that this level of extreme protection is unnecessary for most people, but if you do need it one day, you can go to Settings > Privacy & Security > Lockdown Mode to enable it.
