[Permissions on Android](https://developer.android.com/guide/topics/permissions/overview) grant users control over what apps are allowed to access. Google regularly makes [improvements](https://developer.android.com/about/versions/11/privacy/permissions) on the permission system in each successive version. All user installed apps are strictly [sandboxed](https://source.android.com/security/app-sandbox), therefore there is no need to install any antivirus apps. The savings you make from not purchasing or subscribing to security apps is better spent on paying for a supported device in the future.
Should you want to run an app that you're unsure about, consider using a user or work [profile](android/#android-security-privacy).
## Advanced Protection Program
If you have a Google account we suggest enrolling in the [Advanced Protection Program](https://landing.google.com/advancedprotection/). It is available at no cost to anyone with two or more hardware security keys with [FIDO](/security/multi-factor-authentication.md#fido-fast-identity-online) support.
The Advanced Protection Program provides enhanced threat monitoring and enables:
- Stricter two factor authentication; e.g. that [FIDO](/security/multi-factor-authentication.md#fido-fast-identity-online) **must** be used and disallows the use of SMS OTPs, TOTP, and [OAuth](https://en.wikipedia.org/wiki/OAuth)
- Only Google and verified third party apps can access account data
- Scanning of incoming emails on Gmail accounts for [phishing](https://en.wikipedia.org/wiki/Phishing#Email_phishing) attempts
- Stricter [safe browser scanning](https://www.google.com/chrome/privacy/whitepaper.html#malware) with Google Chrome
- Stricter recovery process for accounts with lost credentials
For users that are using the privileged Google Play Services (common on stock operating systems), the Advanced Protection Program also comes with [additional benefits](https://support.google.com/accounts/answer/9764949?hl=en) such as:
- Not allowing app installation outside of the Google Play Store, the OS vendor's app store, or via [`adb`](https://en.wikipedia.org/wiki/Android_Debug_Bridge)
- Mandatory automatic device scanning with [Play Protect](https://support.google.com/googleplay/answer/2812853?hl=en#zippy=%2Chow-malware-protection-works%2Chow-privacy-alerts-work)
- Warning the user about unverified applications
## SafetyNet and Play Integrity API
[SafetyNet](https://developer.android.com/training/safetynet/attestation) and the [Play Integrity APIs](https://developer.android.com/google/play/integrity) are generally used for [banking apps](https://grapheneos.org/usage#banking-apps). Many banking apps will work fine in GrapheneOS with sandboxed Play services, however some non-financal apps have their own crude anti-tampering mechanisms which might fail. GrapheneOS passes the `basicIntegrity` check, but not the certification check `ctsProfileMatch`. Devices with Android 8 or later have hardware attestation support which cannot be bypassed without leaked keys or serious vulnerabilities.
As for Google Wallet, we don't recommend this due to their [privacy policy](https://payments.google.com/payments/apis-secure/get_legal_document?ldo=0&ldt=privacynotice&ldl=en), which states you must opt-out if you don't want your credit rating and personal information shared with affiliate marketing services.
## Advertising ID
All devices with Google Play Services installed automatically generate an [advertising ID](https://support.google.com/googleplay/android-developer/answer/6048248?hl=en) used for targeted advertising. Disable this feature to limit the data collected about you.
On Android distributions with [Sandboxed Google Play](https://grapheneos.org/usage#sandboxed-google-play), go to ⚙️ Settings → Apps → Sandboxed Google Play → Google Settings → Ads and select **Delete advertising ID**.
On Android distributions with privileged Google Play Services (such as stock OSes), the setting may be in one of several locations. Check
- ⚙️ Settings → Google → Ads
- ⚙️ Settings → Privacy → Ads
Depending on your system, you will either be given the option to delete your advertising ID or to "Opt out of interest-based ads". You should delete the advertising ID if you are given the option to, and if you are not, we recommend that you opt out of interested-based ads and then reset your advertising ID.
