When you install an app and it asks "Allow access to your camera / contacts / location?" — that is a permission request. You are the one in control. You can say no.

Common permissions and what they mean:

• 📍 Location — The app can see exactly where you are in the world. A shopping app does not need this. A maps app does.
• 📷 Camera — The app can take photos or videos using your phone. Grant this only to camera and video-call apps.
• 🎤 Microphone — The app can listen through your phone's mic. Voice assistants and call apps need this. A game usually does not.
• 📒 Contacts — The app can read all the names and numbers saved on your phone. Most apps do not need this.
• 📂 Files / Storage — The app can read and save files on your phone. Photo editors and document apps may need this.
• 📱 Phone / Call Logs — The app can see who you call and read your SMS history. This is very sensitive — rarely needed.

Your phone tracks your location constantly — and many apps share that information without you realising it.

Ways your location can be shared:

• Photos (EXIF data): When you take a photo, your phone secretly embeds your exact GPS coordinates in the image file. If you send that photo, the recipient can find your exact address. Turn this off in Camera Settings → Location Tags → Off.
• Google Maps / Apple Maps: Your location history may be recorded. Check Settings → Location History and turn it off if you don't need it.
• Instagram / Facebook / Snapchat: Posts can include location data. Never add a location tag to photos taken at your home.
• WhatsApp Live Location: Sharing your live location means the other person can watch you move in real time. Only share with people you fully trust.
• Google Family / Find My (Apple): If someone set up these apps on your phone, they may be able to see your location at all times.

Most free apps make money by collecting your data and selling it to advertisers. Here is the kind of information they gather:

• What you search for — every search query you type
• What you buy — purchases, price ranges, brands you browse
• Where you go — your daily movement patterns, home, work, temple, hospital
• Who you talk to — contacts, call duration, message frequency
• How long you use the app — which posts you stop and read, what you skip
• Your device details — phone model, battery level, nearby WiFi networks

What can you do?

• Use a private browser like Firefox Focus or DuckDuckGo for sensitive searches
• Avoid logging into apps with your Facebook or Google account — this links all your data together
• On Android: Settings → Privacy → Ads → Opt out of Ads Personalisation
• On iPhone: Settings → Privacy → Tracking → Allow Apps to Request to Track → Off

A quick app audit takes 10 minutes and can dramatically improve your privacy. Here's how:

1. Open Settings → Apps (or Application Manager) on your phone.
2. Scroll through every installed app. Ask yourself: "Do I use this? Do I recognise it?"
3. For any app you don't use, uninstall it. Unused apps still collect data in the background.
4. For every remaining app, tap it and go to Permissions. Remove any permissions the app does not need for its core function.
5. Check which apps have Background Data or Background App Refresh enabled — turn this off for apps that don't need to update constantly.
6. Look for apps you did not install yourself. These could be installed by someone else — see the Relationship Red Flags page for more.
