App Permissions: What to Allow and What to Deny

By , Cyber Security trainer LinkedIn Published: Last updated:

App permissions control camera, mic, location, contacts and files. Allow only what the app needs for features you use. Deny or set “while using” for location when possible, and review permissions after install — especially for flashlights, wallpapers and unknown APKs.

Quick steps

  1. Install from official App Store / Google Play when you can.
  2. On first prompt, allow only what you need.
  3. Use “While using the app” for location when offered.
  4. Review Settings → Apps → Permissions monthly for important apps.
  5. Uninstall apps that demand odd access.

Why this matters

Isabella in Rome found a flashlight app demanding contacts. Ravi in Vadodara set maps to “while using” location only.

Extra permissions are a privacy and safety risk, not a compliment to the app.

What you need to know

Ask: does this feature need this sensor right now? Prefer: official store apps with limited permissions.

Permission sense

  • Maps location while using — Often OK
  • Flashlight wanting contacts — Deny
  • Mic always for a calculator — Deny

How to do it (step by step)

  1. Install from official App Store / Google Play when you can.
  2. On first prompt, allow only what you need.
  3. Use “While using the app” for location when offered.
  4. Review Settings → Apps → Permissions monthly for important apps.
  5. Uninstall apps that demand odd access.
  6. Avoid unknown APK files from chats.

Example: Isabella removes a greedy flashlight

Isabella denied contacts, uninstalled the flashlight, and used the built-in torch.

Ravi taught his parents to tap Deny when a game asked for SMS.

Both reviewed permission screens after a phone OS update.

Common mistakes

  • Allowing all on first screen “to make it work”.
  • Sideloading APKs from strangers.
  • Never revisiting permissions.

Trusted places to check

Quick revision

  • Least permission needed.
  • While-using for location.
  • No odd APKs.

Ravindra Bagale's Tip

If a simple tool wants your SMS or contacts, that is a smell test — deny.

Quick quiz: check what you learned

  1. A flashlight app asks for your contacts. You should…

    1. Deny contacts and use a built-in torch instead
    2. Allow everything so the light is brighter
    3. Upload your address book to unlock VIP mode
    4. Grant SMS too so it can “verify safety”
    Show answer

    A. Torch apps do not need contacts.

  2. Best location setting for a maps app you use sometimes?

    1. Allow while using the app when that option exists
