A ten-minute privacy settings checklist for every device you own
Most of the privacy exposure on a phone or laptop comes from five settings groups, not fifty. Work through them in order and you can close the obvious gaps on any device in about ten minutes.
Start with location precision
A privacy pass does not have to be exhaustive to be useful. A handful of sections account for most everyday exposure, and the same categories exist on all four systems even when the wording differs.
Begin with location. iOS lists every app under Location Services with an always, while using, or never choice, plus a separate Precise Location switch that lets an app know the neighbourhood without the exact address. Android 12 and later offers the same coarse option inside each app's location permission, and Windows keeps a per-app location list under app permissions.
Cut the advertising ID and app tracking
Every platform hands advertisers a resettable identifier. Android 12 and later lets you delete the advertising ID outright from the ads entry in the privacy section, after which apps receive a string of zeroes instead.
iOS splits the job in two: Allow Apps to Request to Track governs third-party requests, while Apple's own personalised advertising has its own entry. Windows 11 keeps an advertising ID switch on the general page of privacy and security, and macOS puts Apple Advertising in the same pane as the other privacy controls.
Audit microphone and camera access
Both mobile systems now show an indicator dot when the microphone or camera is live, and both keep a history. Android's privacy dashboard lists which apps used the microphone, camera and location in the last day, and iOS offers a comparable report once you switch it on.
Desktops are blunter but still worth checking. Windows lists microphone and camera consumers per app, and macOS does the same, including a screen recording list that fills up quickly after installing meeting software. Revoke anything unfamiliar; apps ask again when they genuinely need access. The macOS and Windows comparison covers how differently the two handle these prompts.
Decide what diagnostics you share
Diagnostics sharing is a single switch on every system, but the default differs. Windows separates required diagnostic data, which cannot be turned off, from optional data, which can.
Apple keeps analytics and improvements inside the privacy section on both iOS and macOS, with separate switches for sharing with Apple and sharing with app developers. Android's usage and diagnostics option lives with the Google account settings rather than the main privacy list, which is why people often miss it.
Close the lock-screen gaps
The lock screen is the part of your privacy that strangers can read without unlocking anything. Notification previews are the main leak: a verification code or a full message body shown on a locked screen defeats the passcode entirely.
iOS handles this with a show previews option you can set to when unlocked, and also lets you choose which panels stay reachable while locked. Android and Windows both offer a sensitive-content setting for lock-screen notifications. The notifications guide and the lock and security guide walk through both sides.
Repeat after every major update
Feature updates add permission categories, move sections and occasionally reset a toggle, so run the pass again after any major version jump. The version change log shows whether a privacy section was renamed or split between releases.
To rehearse the route before touching a real device, open the osimulator settings simulator and follow the same menus, then use the Windows settings hub for the desktop half of the checklist.

Does turning off the advertising ID stop ads?
No. You still see ads, but they are far less personalised because apps can no longer link your activity through a shared identifier.
Is precise location worth turning off?
For weather, news and shopping apps, coarse location is usually enough. Keep precise location only for maps, navigation and anything that needs turn-by-turn accuracy.
How often should I redo this checklist?
Once a year is enough for most people, plus once after each major OS update, since updates can add new permission types.
