El **proyecto de código abierto de Android** es un sistema operativo móvil de código abierto liderado por Google, que está detrás de la mayor parte de los dispositivos móviles del mundo. La mayor parte de los teléfono vendidos con Android son modificados para incluir integraciones y aplicaciones invasivas como los servicios de Google Play, así que puedes mejorar la privacidad de tu dispositivo móvil de manera significativa al reemplazar la instalación predeterminada de tu teléfono con una versión de Android sin esas características invasivas.

## Derivados de AOSP
We recommend installing one of these custom Android operating systems on your device, listed in order of preference, depending on your device's compatibility with these operating systems.
!!! note

![Logotipo de GrapheneOS ](assets/img/android/grapheneos-dark.svg#only-dark){ align=right }
**GrapheneOS** es la mejor opción cuando se trata de privacidad y seguridad. GrapheneOS proporciona mejoras adicionales de [seguridad](https://es.wikipedia.org/wiki/Endurecimiento_(inform%C3%A1tica)) y de privacidad.
### GrapheneOS
!!! recomendación
Los dispositivos de "soporte extendido" de GrapheneOS no tienen correcciones de seguridad completos (actualizaciones de firmware) debido a que el fabricante de equipos originales (OEM) suspende el soporte.
Estos dispositivos no pueden considerarse completamente seguros. 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 is fully supported.

Para complacer a los usuarios que necesitan Google Play Services, CalyxOS incluye de manera opcional [MicroG](https://microg.org/). Con MicroG, CalyxOS también se incluye en los servicios de localización de [Mozilla](https://location.services.mozilla.com/) y [DejaVu](https://github.com/n76/DejaVu).
Google Pixel phones are the only devices that currently meet GrapheneOS's [hardware security requirements](https://grapheneos.org/faq#device-support).
### CalyxOS
!!! recomendación
![CalyxOS logo](assets/img/android/calyxos.svg){ align=right }
**CalyxOS** es una alternativa aceptable a GrapheneOS.
Tiene algunas funciones de privacidad además de AOSP, que incluyen [Datura firewall](https://calyxos.org/docs/tech/datura-details), [Signal](https://signal.org) integración en la aplicación de marcación y un botón de pánico incorporado. CalyxOS también viene con actualizaciones de firmware y compilaciones firmadas, así que [el arranque verificado](https://source.android.com/security/verifiedboot) es completamente compatible.

DivestOS has automated kernel vulnerability ([CVE](https://en.wikipedia.org/wiki/Common_Vulnerabilities_and_Exposures)) [patching](https://gitlab.com/divested-mobile/cve_checker), fewer proprietary blobs, and a custom [hosts](https://divested.dev/index.php?page=dnsbl) file. recommendation DivestOS also includes kernel patches from GrapheneOS and enables all available kernel security features via [defconfig hardening](https://github.com/Divested-Mobile/DivestOS-Build/blob/master/Scripts/Common/Functions.sh#L758). All kernels newer than version 3.4 include full page [sanitization](https://lwn.net/Articles/334747/) and all ~22 Clang-compiled kernels have [`-ftrivial-auto-var-init=zero`](https://reviews.llvm.org/D54604?id=174471) enabled.
DivestOS ha automatizado el [parchamiento vulnerabilidad del kernel](https://gitlab.com/divested-mobile/cve_checker) ([CVE](https://en.wikipedia.org/wiki/Common_Vulnerabilities_and_Exposures)), menos blobs propietarios, un archivo personalizado de [hosts](https://divested.dev/index.php?page=dnsbl), y [F-Droid](https://www.f-droid.org) como tienda de aplicaciones. Incluye [UnifiedNlp](https://github.com/microg/UnifiedNlp) para la localización de la red. 17.1 and higher features GrapheneOS's per-network full [MAC randomization](https://en.wikipedia.org/wiki/MAC_address#Randomization) option, [`ptrace_scope`](https://www.kernel.org/doc/html/latest/admin-guide/LSM/Yama.html) control, and automatic reboot/Wi-Fi/Bluetooth [timeout options](https://grapheneos.org/features).
DivestOS también incluye parches de GrapheneOS para el kernel y habilita todas las características de seguridad del kernel disponibles a través de [endurecimiento defconfig](https://github.com/Divested-Mobile/DivestOS-Build/blob/master/Scripts/Common/Functions.sh#L758). Todos los kernels más recientes que la versión 3.4 incluyen [saneamiento](https://lwn.net/Articles/334747/) página completa y todos los ~22 kernels compilados por Clang tienen [`-ftrivial-auto-var-init=zero`](https://reviews.llvm.org/D54604?id=174471) habilitado. However, doing so on DivestOS isn't viable; the developers update their apps via their own F-Droid repositories ([DivestOS Official](https://divestos.org/fdroid/official/?fingerprint=E4BE8D6ABFA4D9D4FEEF03CDDA7FF62A73FD64B75566F6DD4E5E577550BE8467) and [DivestOS WebView](https://divestos.org/fdroid/webview/?fingerprint=FB426DA1750A53D7724C8A582B4D34174E64A84B38940E5D5A802E1DFF9A40D2)). We recommend disabling the official F-Droid app and using [Neo Store](https://github.com/NeoApplications/Neo-Store/) with the DivestOS repositories enabled to keep those components up to date. For other apps, our recommended methods of obtaining them still apply.
!!! warning
DivestOS firmware update [status](https://gitlab.com/divested-mobile/firmware-empty/-/blob/master/STATUS) and quality control varies across the devices it supports. We still recommend GrapheneOS depending on your device's compatibility. For other devices, DivestOS is a good alternative.
Not all of the supported devices have verified boot, and some perform it better than others.
## Android Devices
When purchasing a device, we recommend getting one as new as possible. The software and firmware of mobile devices are only supported for a limited time, so buying new extends that lifespan as much as possible.
Avoid buying phones from mobile network operators. These often have a **locked bootloader** and do not support [OEM unlocking](https://source.android.com/devices/bootloader/locking_unlocking). These phone variants will prevent you from installing any kind of alternative Android distribution.
Be very **careful** about buying second hand phones from online marketplaces. Always check the reputation of the seller. If the device is stolen, there's a possibility of [IMEI blacklisting](https://www.gsma.com/security/resources/imei-blacklisting/). There is also a risk involved with you being associated with the activity of the previous owner.
A few more tips regarding Android devices and operating system compatibility:
- Do not buy devices that have reached or are near their end-of-life, additional firmware updates must be provided by the manufacturer.
- Do not buy preloaded LineageOS or /e/ OS phones or any Android phones without proper [Verified Boot](https://source.android.com/security/verifiedboot) support and firmware updates. These devices also have no way for you to check whether they've been tampered with.
- In short, if a device or Android distribution is not listed here, there is probably a good reason. Check out our [forum](https://discuss.privacyguides.net/) to find details!
### DivestOS
Google Pixel phones are the **only** devices we recommend for purchase. Pixel phones have stronger hardware security than any other Android devices currently on the market, due to proper AVB support for third-party operating systems and Google's custom [Titan](https://security.googleblog.com/2021/10/pixel-6-setting-new-standard-for-mobile.html) security chips acting as the Secure Element.
!!! recomendación
![Logotipo de DivestOS](assets/img/android/divestos.svg){ align=right }
**DivestOS** es un [soft-fork](https://es. wikipedia.org/wiki/Bifurcaci%C3%B3n_(desarrollo_de_software)) de [LineageOS](https://lineageos.org/).
DivestOS hereda muchos [dispositivos soportados](https://divestos.org/index.php?page=devices&base=LineageOS) de LineageOS.
Tiene builds firmados, lo que permite tener [arranque verificado](https://source.android.com/security/verifiedboot) en algunos dispositivos que no son Pixel.
Secure Elements like the Titan M2 are more limited than the processor's Trusted Execution Environment used by most other phones as they are only used for secrets storage, hardware attestation, and rate limiting, not for running "trusted" programs. Phones without a Secure Element have to use the TEE for *all* of those functions, resulting in a larger attack surface.
Google Pixel phones use a TEE OS called Trusty which is [open-source](https://source.android.com/security/trusty#whyTrusty), unlike many other phones.
The installation of GrapheneOS on a Pixel phone is easy with their [web installer](https://grapheneos.org/install/web). If you don't feel comfortable doing it yourself and are willing to spend a bit of extra money, check out the [NitroPhone](https://shop.nitrokey.com/shop) as they come preloaded with GrapheneOS from the reputable [Nitrokey](https://www.nitrokey.com/about) company.
A few more tips for purchasing a Google Pixel:
- If you're after a bargain on a Pixel device, we suggest buying an "**a**" model, just after the next flagship is released. Discounts are usually available because Google will be trying to clear their stock.
- Consider price beating options and specials offered at physical stores.
- Look at online community bargain sites in your country. These can alert you to good sales.
- Google provides a list showing the [support cycle](https://support.google.com/nexus/answer/4457705) for each one of their devices. The price per day for a device can be calculated as: $\text{Cost} \over \text {EOL Date}-\text{Current Date}$, meaning that the longer use of the device the lower cost per day.
## General Apps
We recommend a wide variety of Android apps throughout this site. The apps listed here are Android-exclusive and specifically enhance or replace key system functionality.
### Perfiles de usuario

![Shelter logo](assets/img/android/shelter.svg){ align=right }
**Shelter** is an app that helps you leverage Android's Work Profile functionality to isolate or duplicate apps on your device.
Shelter supports blocking contact search cross profiles and sharing files across profiles via the default file manager ([DocumentsUI](https://source.android.com/devices/architecture/modular-system/documentsui)).

![Auditor logo](assets/img/android/auditor-dark.svg#only-dark){ align=right }
**Auditor** is an app which leverages hardware security features to provide device integrity monitoring for [supported devices](https://attestation.app/about#device-support). Currently, it only works with GrapheneOS and the device's stock operating system.

- [:simple-github: GitHub](https://github.com/GrapheneOS/Auditor/releases)
- [:material-cube-outline: GrapheneOS App Store](https://github.com/GrapheneOS/Apps/releases)
Auditor performs attestation and intrusion detection by:
- Using a [Trust On First Use (TOFU)](https://en.wikipedia.org/wiki/Trust_on_first_use) model between an *auditor* and *auditee*, the pair establish a private key in the [hardware-backed keystore](https://source.android.com/security/keystore/) of the *Auditor*.
- The *auditor* can either be another instance of the Auditor app or the [Remote Attestation Service](https://attestation.app).
- The *auditor* records the current state and configuration of the *auditee*.
- Should tampering with the operating system of the *auditee* happen after the pairing is complete, the auditor will be aware of the change in the device state and configurations.
- You will be alerted to the change.
No personally identifiable information is submitted to the attestation service. We recommend that you sign up with an anonymous account and enable remote attestation for continuous monitoring.
If your [threat model](basics/threat-modeling.md) requires privacy, you could consider using [Orbot](tor.md#orbot) or a VPN to hide your IP address from the attestation service. To make sure that your hardware and operating system is genuine, [perform local attestation](https://grapheneos.org/install/web#verifying-installation) immediately after the device has been installed and prior to any internet connection.

- Use of the new [Media](https://developer.android.com/training/data-storage/shared/media) API, therefore [storage permissions](https://developer.android.com/training/data-storage) are not required
- Microphone permission not required unless you want to record sound
!!! note
Metadata is not currently deleted from video files but that is planned.
The image orientation metadata is not deleted. If you enable location (in Secure Camera) that **won't** be deleted either. If you want to delete that later you will need to use an external app such as [ExifEraser](data-redaction.md#exiferaser).

**Secure PDF Viewer** is a PDF viewer based on [pdf.js](https://en.wikipedia.org/wiki/PDF.js) that doesn't require any permissions. The PDF is fed into a [sandboxed](https://en.wikipedia.org/wiki/Sandbox_(software_development)) [webview](https://developer.android.com/guide/webapps/webview). This means that it doesn't require permission directly to access content or files.
[Content-Security-Policy](https://en.wikipedia.org/wiki/Content_Security_Policy) is used to enforce that the JavaScript and styling properties within the WebView are entirely static content.

## Obtaining Applications
### Interruptores globales
GrapheneOS's app store is available on [GitHub](https://github.com/GrapheneOS/Apps/releases). It supports Android 12 and above and is capable of updating itself. The app store has standalone applications built by the GrapheneOS project such as the [Auditor](https://attestation.app/), [Camera](https://github.com/GrapheneOS/Camera), and [PDF Viewer](https://github.com/GrapheneOS/PdfViewer). If you are looking for these applications, we highly recommend that you get them from GrapheneOS's app store instead of the Play Store, as the apps on their store are signed by the GrapheneOS's project own signature that Google does not have access to.
### Orbot
The Google Play Store requires a Google account to login which is not great for privacy. You can get around this by using an alternative client, such as Aurora Store.
!!! recomendación
![Aurora Store logo](assets/img/android/aurora-store.webp){ align=right }
**Aurora Store** is a Google Play Store client which does not require a Google Account, Google Play Services, or microG to download apps.
[:octicons-home-16: Homepage](https://auroraoss.com/){ .md-button .md-button--primary }
[:octicons-code-16:](https://gitlab.com/AuroraOSS/AuroraStore){ .card-link title="Source Code" }
??? downloads
- [:simple-gitlab: GitLab](https://gitlab.com/AuroraOSS/AuroraStore/-/releases)
Aurora Store does not allow you to download paid apps with their anonymous account feature. You can optionally log in with your Google account with Aurora Store to download apps you have purchased, which does give access to the list of apps you've installed to Google, however you still benefit from not requiring the full Google Play client and Google Play Services or microG on your device.
### Shelter
For apps that are released on platforms like GitHub and GitLab, you may be able to add an RSS feed to your [news aggregator](/news-aggregators) that will help you keep track of new releases.
![RSS APK](./assets/img/android/rss-apk-light.png#only-light) ![RSS APK](./assets/img/android/rss-apk-dark.png#only-dark) ![APK Changes](./assets/img/android/rss-changes-light.png#only-light) ![APK Changes](./assets/img/android/rss-changes-dark.png#only-dark)
#### GitHub
On GitHub, using [Secure Camera](#secure-camera) as an example, you would navigate to its [releases page](https://github.com/GrapheneOS/Camera/releases) and append `.atom` to the URL:
`https://github.com/GrapheneOS/Camera/releases.atom`
#### GitLab
On GitLab, using [Aurora Store](#aurora-store) as an example, you would navigate to its [project repository](https://gitlab.com/AuroraOSS/AuroraStore) and append `/-/tags?format=atom` to the URL:
`https://gitlab.com/AuroraOSS/AuroraStore/-/tags?format=atom`
#### Verifying APK Fingerprints
If you download APK files to install manually, you can verify their signature with the [`apksigner`](https://developer.android.com/studio/command-line/apksigner) tool, which is a part of Android [build-tools](https://developer.android.com/studio/releases/build-tools).
1. Install [Java JDK](https://www.oracle.com/java/technologies/downloads/).
2. Download the [Android Studio command line tools](https://developer.android.com/studio#command-tools).
3. Extract the downloaded archive:
```bash
unzip commandlinetools-*.zip
cd cmdline-tools
./bin/sdkmanager --sdk_root=./ "build-tools;29.0.3"
```
4. Run the signature verification command:
```bash
./build-tools/29.0.3/apksigner verify --print-certs ../Camera-37.apk
```
5. The resulting hashes can then be compared with another source. Some developers such as Signal [show the fingerprints](https://signal.org/android/apk/) on their website.
```bash
Signer #1 certificate DN: CN=GrapheneOS
Signer #1 certificate SHA-256 digest: 6436b155b917c2f9a9ed1d15c4993a5968ffabc94947c13f2aeee14b7b27ed59
Signer #1 certificate SHA-1 digest: 23e108677a2e1b1d6e6b056f3bb951df7ad5570c

```
### Auditor
![F-Droid logo](assets/img/android/f-droid.svg){ align=right width=120px }
==We do **not** currently recommend F-Droid as a way to obtain apps.== F-Droid is often recommended as an alternative to Google Play, particularly in the privacy community. The option to add third-party repositories and not be confined to Google's walled garden has led to its popularity. F-Droid additionally has [reproducible builds](https://f-droid.org/en/docs/Reproducible_Builds/) for some applications and is dedicated to free and open-source software. However, there are [notable problems](https://privsec.dev/posts/android/f-droid-security-issues/) with the official F-Droid client, their quality control, and how they build, sign, and deliver packages.
Due to their process of building apps, apps in the official F-Droid repository often fall behind on updates. F-Droid maintainers also reuse package IDs while signing apps with their own keys, which is not ideal as it gives the F-Droid team ultimate trust.
Other popular third-party repositories such as [IzzyOnDroid](https://apt.izzysoft.de/fdroid/) alleviate some of these concerns. The IzzyOnDroid repository pulls builds directly from GitHub and is the next best thing to the developers' own repositories. However, it is not something that we can recommend, as apps are typically [removed](https://github.com/vfsfitvnm/ViMusic/issues/240#issuecomment-1225564446) from that respository when they make it to the main F-Droid repository. While that makes sense (since the goal of that particular repository is to host apps before they're accepted into the main F-Droid repository), it can leave you with installed apps which no longer receive updates.
That said, the [F-Droid](https://f-droid.org/en/packages/) and [IzzyOnDroid](https://apt.izzysoft.de/fdroid/) repositories are home to countless apps, so they can be a useful tool to search for and discover open-source apps that you can then download through Play Store, Aurora Store, or by getting the APK directly from the developer. It is important to keep in mind that some apps in these repositories have not been updated in years and may rely on unsupported libraries, among other things, posing a potential security risk. You should use your best judgement when looking for new apps via this method.
!!! note
In some rare cases, the developer of an app will only distribute it through F-Droid ([Gadgetbridge](https://gadgetbridge.org/) is one example of this). If you really need an app like that, we recommend using [Neo Store](https://github.com/NeoApplications/Neo-Store/) instead of the official F-Droid app to obtain it.
