+It's also recommended to disable battery optimisations for Conversations and Orbot. If you don't do that then you may have trouble receiving messages or some partts of the protocol may break. That can be done by going to *Settings*, selecting *Battery* then opening the menu (top right) and selecting *Battery optimisations* then selecting *Not optimised* and *All apps*, then finally choosing Conversations and Orbot not to be optimised.

 Even with free software apps it's not difficult to get into a situation where your battery doesn't last for long. To maximize battery life access RSS feeds via the onion-based mobile reader within a Tor-compatible browser and not from a locally installed RSS app.

 If you have Syncthing installed then change the settings so that it only syncs when charging and when on wifi. Avoid any apps which might be continuously polling and preventing the device from going into sleep mode when it's not used.

 If you're using the Riot mobile app to access a Matrix homeserver then you can significantly improve battery performance by going to the settings and changing *Sync request timeout* to 30 seconds and *Delay between two sync requests* to 600 seconds.

 * Blocking bad domains

 You can block known bad domains by editing the */system/etc/hosts* file on your device. It is possible to use extensive ad-blocking hosts files used by other ad-blocking systems such as pi-hole, but merely blocking Facebook and Google Analytics will protect you against much of the corporate surveillance which goes on. Even if you don't have a Facebook account this may still be useful since they will still try to create a "ghost profile" of you, so the less data they have the better.

 Tor Messenger is a messaging client which supports XMPP, and its onion routing enables you to protect the metadata of chat interactions to some extent by making it difficult for an adversary to know which server is talking to which. You can download Tor Messenger from <a href="https://torproject.org">torproject.org</a> and the setup is pretty simple.

 Use a Linux based phone operating system. Typically this will mean Android, but could also mean LineageOS or Replicant. LineageOS is the most preferable, because you can usually get an up to date image with a recent kernel which will give you better security against exploits. If you're buying a phone then look for a model which is supported by LineageOS. Replicant is the most free (as in freedom) but only runs on a small number of phone models. If you have a phone which runs a full GNU/Linux system then that's fantastic, and you can probably use it in much the same way as a desktop system and the rest of the advice on this page won't apply. If you don't have a phone capable of running a Linux based operating system then consider selling, giving away or bartering your existing one.

 So maybe you're running Android and the phone came with some apps already installed. Almost certainly they'll be proprietary. Go to Settings/Apps and then uninstall or deactivate any apps which you really don't need. Mostly preinstalled apps are intended to send your data to companies who will then sell it to advertisers or governments under the business model of <i>surveillance capital</i>. It's not a good idea to get caught up in that, and to avoid becoming addicted to apps which are surveilling you without consent or installing spyware in the background without your knowledge.

 Encrypt your phone. This can usually be done via <b>Settings/Security</b> and you may need to fully charge the phone first. Encryption means that if you lose your phone or it gets stolen then there is less chance that anyone who picks it up will get access to your data, photos and so on.

 Add a lock screen, preferably with a password which is not easy for other people to guess or for quicker access with a PIN number. Install an app called <b>Locker</b>, activate it and set the maximum number of password guesses to ten (or whatever you feel comfortable with). If bad people get hold of your phone then they may try to brute force your lock screen password or PIN (i.e. automatically trying millions of common word and number combinations) and the locker app will prevent them from succeeding by resetting the phone back to its factory default condition and wiping the data.

 Both governments and corporations want to compile matadata dossiers about you. Who you communicated with, when and how often. They want this so that they can data mine, simulate, predict and then ultimately influence (sometimes also called "nudge") your actions and preferences in the directions they prefer. By routing your connections through a number of proxy servers (Tor routers) you can make it perhaps not <i>theoretically</i> impossible but at least <i>very hard</i> for them to have a complete and accurate list of who your friends are, your religion, politics, likely health issues, sexual orientation and what news sites or books you read.

 The easiest way to access email is by installing the <a href="./app_mailpile.html">Mailpile</a> app. This keeps your GPG keys off of possibly insecure mobile devices but still enables encrypted email communications in an easy way. You can use K9 mail if you prefer, but that will require installing OpenKeychain and having your GPG keys on the device, which is a lot more risky.

+It's also recommended to disable battery optimisations for Conversations and Orbot. If you don't do that then you may have trouble receiving messages or some partts of the protocol may break. That can be done by going to <b>Settings</b>, selecting <b>Battery</b> then opening the menu (top right) and selecting <b>Battery optimisations</b> then selecting <b>Not optimised</b> and <b>All apps</b>, then finally choosing Conversations and Orbot not to be optimised.

 You can block known bad domains by editing the <b>/system/etc/hosts</b> file on your device. It is possible to use extensive ad-blocking hosts files used by other ad-blocking systems such as pi-hole, but merely blocking Facebook and Google Analytics will protect you against much of the corporate surveillance which goes on. Even if you don't have a Facebook account this may still be useful since they will still try to create a "ghost profile" of you, so the less data they have the better.
