Source: https://playciso.com/blog/iphone-privacy-settings-checklist · Published: 2026-11-07 · Publisher: PlayCISO (https://playciso.com) --- **The quickest way to tighten an iPhone is to open Settings, go to Privacy & Security, check which apps can reach what, and run Safety Check.** Then protect the phone itself and the Apple Account behind it. This checklist goes through the settings that matter most, says what each does, and says what it costs you. iOS menu names and wording change between versions, so where the exact path matters we link Apple's own pages instead of promising a menu. No single setting is "most private". Each trades some convenience, recoverability or features for protection, and the right answer depends on how you use the phone. If you already suspect something is wrong, start with [how to know if your phone is hacked](/blog/how-to-know-if-your-phone-is-hacked) and the [Phone Hacked Triage Lab](/tools/phone-hacked-triage-lab); this page is about getting the settings right before anything goes wrong. ## Do this now: the 15-minute pass - Open Settings, then Privacy & Security. Apple's pages place Safety Check, Tracking and Lockdown Mode here. Look through the lists of apps that have asked for location, camera, microphone, photos and contacts. - Run Safety Check (iOS 16 or later) and use Manage Sharing & Access to see who you share with. - Use a strong passcode and turn on Stolen Device Protection. - Check your Apple Account: two-factor authentication on, and a recovery contact added. - Keep Find My on, so you can locate, lock or erase the phone. - Hide message previews on the lock screen, if people can see your phone. - Decide about Advanced Data Protection only after reading the recovery trade-off below. You can rehearse these choices in the [iPhone Privacy Lab](/tools/iphone-privacy-lab), a scenario with fictional people where nothing real is at stake. ## Safety Check: who can see what Apple's Personal Safety guide describes Safety Check as a feature in Settings, under Privacy & Security, that helps you review and stop sharing your information with individual people and apps. It needs an iPhone with iOS 16 or later and an Apple Account that uses two-factor authentication. It has two options: - Manage Sharing & Access is selective: you go through people and apps one at a time, then review account steps such as connected devices, verification phone numbers, your password and your emergency contacts. - Emergency Reset is all or nothing: Apple describes it as an immediate and universal reset of sharing for all people and apps. The trade-offs are practical. Emergency Reset is meant for urgent situations; afterwards you must re-share with people you want to keep, and Apple notes that some apps notify people when sharing resumes. Apple also says Safety Check cannot review non-Apple accounts, social media sharing or devices signed in to a different Apple Account. ## App permissions: location, camera, microphone, photos, contacts Under Privacy & Security, the categories list the apps that have asked for access, and you can change an answer later. We have not verified the exact wording of every prompt for every iOS version, so use Apple's iPhone User Guide for the current steps. The principle is simple: grant what the feature needs and nothing more. A running app needs location while you use it, not your contacts or microphone. The cost of denying is that a feature may stop working, and you can grant access again when you need it. ## App Tracking Transparency Apple says apps must ask permission before tracking your activity across other companies' apps and websites. If you choose *Ask App Not to Track*, the developer cannot access your advertising identifier. Apple also says that, with the Allow Apps to Request to Track setting turned off under Privacy & Security, then Tracking, each app that asks is treated as if you chose Ask App Not to Track. You keep full use of the app either way. The cost is ads that are less tailored; you will still see ads, and the app can still see what you do inside it. ## Passcode and Face ID Face ID and Touch ID are convenient, but the passcode is still the fallback, and it is what someone who watches you type it can learn. A longer passcode is harder to guess or observe. Many of the protections below depend on a passcode being set. The trade-off is a little more typing. ## Stolen Device Protection Apple says Stolen Device Protection needs iOS 17.3 or later and must be turned on *before* the iPhone is lost or stolen. It requires two-factor authentication for your Apple Account, a passcode, Face ID or Touch ID, Significant Locations and Find My. You can find it in Settings, under Face ID & Passcode, and it may already be on. - Away from familiar places such as home or work, actions like using saved passwords or passkeys, turning off Lost Mode or erasing the phone require Face ID or Touch ID, with no passcode fallback. - Security delay: changing your Apple Account password, signing out, changing your passcode or turning off the feature needs Face ID or Touch ID, then a one-hour wait, then another Face ID or Touch ID. - Always mode: you can choose to require the delay everywhere, including at home. The cost is that genuine changes are slower when you are out and about, and Apple says Find My cannot be turned off while it is on. Turn it off before you sell or trade in the phone. ## Apple Account: two-factor authentication and recovery Safety Check, Stolen Device Protection and recovery contacts all assume two-factor authentication on your Apple Account. A **recovery contact** is a trusted person you add in your account settings. Apple says they do not get access to your account; they can only help you get a code to regain access, and both of you need two-factor authentication. Choose someone you can reach by phone or in person. The cost is trusting one person with that role; you can have more than one. For a stronger sign-in in general, see our [Passkey Lab](/tools/passkey-lab). ## iCloud and Advanced Data Protection Apple describes Advanced Data Protection as an optional setting that uses end-to-end encryption for more of your iCloud data, so only your trusted devices hold the keys. It raises the end-to-end encrypted categories from 15 to 25, adding iCloud Backup, Photos and Notes. The catch, in Apple's words: it will not have the encryption keys to help you recover your data. Your options are your device passcode, a recovery contact or a personal recovery key, and Apple guides you to set one up before turning it on. - iCloud Mail, Contacts and Calendars are not end-to-end encrypted under it. - Shared content is end-to-end encrypted only when every participant has it on. - Access through iCloud.com is turned off by default. - You can turn it off at any time. Choose it if you value privacy from the cloud and will keep a recovery key safe. Skip it, which is a fair choice, if the risk of being locked out worries you more. ## Lockdown Mode: who it is for Apple says Lockdown Mode is an optional, extreme protection to use only if you believe you may be targeted by a highly sophisticated cyberattack, and that most people are never targeted this way. It blocks most message attachments other than images, turns off some complex web technologies, blocks incoming invitations such as FaceTime calls from people you have not contacted, blocks wired connections while locked and prevents installing new configuration profiles. The trade-off is that ordinary things stop working normally. You turn it on under Settings, Privacy & Security, Lockdown Mode, and it needs a restart. ## Find My and lock screen notifications **Find My** lets you locate, lock or erase a lost phone, and Apple lists it as a requirement for Stolen Device Protection. Leave it on. Sharing your location with *people* is a separate matter, which Safety Check reviews. **Lock screen previews** can show message text and one-time codes to anyone who glances at the phone. Hiding the content costs one extra tap. The setting lives in the Settings app; we have not verified its current menu name, so check Apple's iPhone User Guide. ## Mail Privacy Protection and Private Relay Apple says Mail Privacy Protection keeps email senders from learning about your Mail activity: Protect Mail Activity downloads remote content in the background by default, through two relays run by different entities, so no single party can link your IP address to the content. Hide IP Address is a separate toggle. Both are on by default, and the trade-off is that senders get less data about you. **iCloud Private Relay** is part of iCloud+ and is not available in all countries or regions. Apple says Safari requests go through two relays so that no single party can see both who you are and which sites you visit. The costs Apple lists: some websites may require extra steps to sign in, and some speed tests may show lower results. It covers Safari browsing, not everything the phone does, and it is not a full VPN. ## How to tell your settings are working - Safety Check shows only people and apps you recognise. - The Tracking list shows no app with permission you did not intend. - Stolen Device Protection shows as on in Face ID & Passcode. - Your Apple Account lists only your own devices and phone numbers. If something looks wrong, such as an unknown device on your account, change your Apple Account password and follow the steps in [how to know if your phone is hacked](/blog/how-to-know-if-your-phone-is-hacked). ## Prevent it next time: a checklist - Run Safety Check every few months and after a breakup, a move or a new job. - Review app permissions after installing something new. - Use a longer passcode and keep Stolen Device Protection on. - Keep two-factor authentication on and a recovery contact in place. - If you turn on Advanced Data Protection, store your recovery key safely first. - Keep Lockdown Mode for when you really need it. - Check what is publicly findable about you with the [Digital Footprint Check](/tools/digital-footprint-check). ## Frequently asked questions ### What are the most important iPhone privacy settings? Start in Settings under Privacy & Security: review which apps can reach your location, camera, microphone, photos and contacts, and run Safety Check. Then protect the phone and the account: a strong passcode, Stolen Device Protection, two-factor authentication and a recovery contact. ### What does Stolen Device Protection do? Apple says that away from familiar places such as home or work, it requires Face ID or Touch ID for actions like using saved passwords, and adds a one-hour wait for changes such as your Apple Account password or passcode. It needs iOS 17.3 or later and must be on before the phone is lost or stolen. ### Should I turn on Lockdown Mode? Probably not. Apple calls it an extreme, optional protection for people who may be targeted by highly sophisticated attacks and says most people are never targeted that way. It limits message attachments, some web technologies and incoming FaceTime invitations. ### What is the downside of Advanced Data Protection? Apple says it will not have the encryption keys, so it cannot help you recover that data if you lose access. You need a recovery contact or recovery key. iCloud Mail, Contacts and Calendar are not end-to-end encrypted under it. ### Can a recovery contact get into my Apple Account? No. Apple says a recovery contact does not have access to your account and can only give you a code to help you regain access. ### Does Private Relay work everywhere? No. Apple says it is part of iCloud+, is not available in all countries or regions, and covers Safari browsing. Some websites may need extra sign-in steps with it on. ## Sources - [Apple Personal Safety guide: Safety Check for an iPhone with iOS 16 or later](https://support.apple.com/guide/personal-safety/safety-check-iphone-ios-16-ips2aad835e1/web) - [Apple Support: About Stolen Device Protection for iPhone](https://support.apple.com/en-us/120340) - [Apple Support: Advanced Data Protection for iCloud](https://support.apple.com/en-us/102651) - [Apple Personal Safety guide: Harden your devices with Lockdown Mode](https://support.apple.com/guide/personal-safety/harden-your-devices-with-lockdown-mode-ipsd5baf79d0/web) - [Apple Support: If an app asks to track your activity](https://support.apple.com/en-us/102420) - [Apple Support: Set up a recovery contact for your Apple Account](https://support.apple.com/en-us/102641) - [Apple Legal: Mail Privacy Protection](https://www.apple.com/legal/privacy/data/en/mail-privacy-protection/) - [Apple Support: About iCloud Private Relay](https://support.apple.com/en-us/102602) *This is general guidance.
