   **Orbot** is a free proxy app that routes your connections through the Tor Network.
 
-  Orbot can proxy individual apps if they support SOCKS or HTTP proxying. It can also proxy all your network connections using the [VpnService](https://developer.android.com/reference/android/net/VpnService) and can be used with the VPN killswitch (⚙️ Settings → Network & internet → VPN → ⚙️ → Block connections without VPN).

   For resistance against traffic analysis attacks, consider enabling *Isolate Destination Address* ( ⁝ →Settings → Connectivity). This will use a completely different Tor Circuit (different middle relay and exit nodes) for every domain you connect to.

   Orbot is often outdated on the Guardian Project's [F-Droid repository](https://guardianproject.info/fdroid) and [Google Play](https://play.google.com/store/apps/details?id=org.torproject.android) so consider downloading directly from the [GitHub repository](https://github.com/guardianproject/orbot) instead.
 
   All versions are signed using the same signature so they should be compatible with each other.

   **GrapheneOS** is the best choice when it comes to privacy and security.
 
-  GrapheneOS has a lot of security hardening and privacy improvements. It has a [hardened memory allocator](https://github.com/GrapheneOS/hardened_malloc), network and sensor permissions, and various other [security features](https://grapheneos.org/features). GrapheneOS also comes with full firmware updates and signed builds, so [verified boot](https://source.android.com/security/verifiedboot) is fully supported.

   Notably, GrapheneOS supports [Sandboxed Play Services](https://grapheneos.org/usage#sandboxed-play-services). Google Play Services can be run fully sandboxed like a regular user app and contained in a work profile or user [profile](/android/#android-security-privacy) of your choice. This means that you can run apps dependant on Play Services, such as those that require push notifications using Google's [Firebase Cloud Messaging](https://firebase.google.com/docs/cloud-messaging/) service. GrapheneOS allows you to take advantage of most [Google Play Services](https://en.wikipedia.org/wiki/Google_Play_Services) whilst having full user control over their permissions and access.

   To accomodate users who need Google Play Services, CalyxOS optionally includes [MicroG](https://microg.org/). With MicroG, CalyxOS also bundles in the [Mozilla](https://location.services.mozilla.com/) and [DejaVu](https://github.com/n76/DejaVu) location services.

   Like CalyxOS's firewall, the network access toggle can also leak in [some](https://gitlab.com/LineageOS/issues/android/-/issues/3228) situations.
