Signal's Stories feature works similarly to Instagram or Snapchat, where a photo or video exists in the app for a set amount of time. Like a social network, you can control who can see these stories:

Regulatory Signs ev. STOP. YIELD. BJ [CJ RIGHT TURN ... HIGHWAY. -DlI/IDED. HIGHWAY. ONLY. ~ LEFT TtlRN. ONLY ... Warning Signs. RIGHT. LEFT. RIGHT. LEFT. RIGHT.

As with most chat apps, communications can be made between either individuals or a group, allowing you to send end-to-end encrypted text, picture, audio and video messages, as well as live video and audio calls. Everyone must have the Signal app installed to communicate with each other. Encrypted calls and messages use your data connection, so both parties in the conversation must have internet access on their mobile devices. Due to this, you will not incur SMS and MMS fees when using Signal.

Keeping your Taser in tip-top shape means paying attention to all its components, especially the stun dart cartridges. These cartridges are the heart of your Taser’s defensive capabilities, launching the darts that carry the electrical charge to neutralize a potential threat. Cartridges can expire or deplete over time or after use, which could leave you in a bind when you need your Taser the most. Regular checks and timely replacements of these cartridges ensure your device is ready and reliable whenever you need to assert your safety. A small step plays a significant role in your overall preparedness. By maintaining your Taser, you’re investing in the device’s longevity and, more importantly, in your continued protection and peace of mind.

Signal's default setup is relatively secure, but there are a few things to consider changing, and some features you may want to tinker with.

Signal can send a link preview when you send a contact a link to a website. This generates a preview image along with the link instead of just showing the text of the URL. This may leak the fact you're sharing on Signal to the website (though the site still wouldn't know anything more than that). These are disabled by default, but if you've enabled them and want to turn them off, you can.

Now, when you send the photo or video, the recipient can only view that content one time, but keep in mind they can still take a screenshot of it.

Signal is a free and open-source application for Android, iOS, and desktop that employs end-to-end encryption to keep communications safe. Signal has certified to courts that it only maintains two types of user data available to law enforcement: timestamps of when each account was created and the date that each account last connected to the Signal service.

Next up is creating a profile and a PIN. The profile image and name you choose will be shown to any contacts you have saved in your address book, when you initiate or accept new chats, and when you join new groups. While a first name (either genuine or made up) is required, the image and last name are optional. A PIN keeps your information safe on Signal’s servers, and if you switch phones you will be able to recover your settings, profile, and contacts using it.

If you previously allowed Signal access to your contacts, you will see a list of all the registered Signal users in your contacts. Pick the person you want to message, or type in a phone number. From this screen, you can start chatting, or initiate a phone (or video) call. If you're using Signal on Android, you can initiate calls from the call tab, as well.

You will see a string of 60 numbers and a QR code. Match the color cards with the person you're verifying with, and then you can either verify by manually reading off these numbers to make sure they correspond with your contact's numbers, or if you're in the same location, you can scan the QR code that appears on this screen. If needed, you can also copy the numbers and share it over a secondary secure channel. Once verified, tap the "Mark as verified" button.

Finding the sweet spot for Taser use is key to maximizing its effectiveness while ensuring your safety. The optimal distance for deploying a Taser is within 15 feet of the target. This range strikes a perfect balance, allowing the electrical probes to achieve a solid and effective connection, ensuring the Taser does its job efficiently. Practicing at this ideal distance prepares you for real-life scenarios, helping you become more proficient with your device. It enhances your ability to accurately aim and deploy the Taser under stress, reinforcing your readiness to defend yourself effectively when it matters most. Remember, familiarity with your Taser’s performance across different distances fortifies your confidence and competence in using it as a powerful tool for self-defense.

Beyond their capability to disable threats from a distance, Taser guns offer an added layer of versatility by doubling as direct contact stun guns. This feature is especially useful in situations where space is limited or when you find yourself too close for a dart deployment. By removing the dart cartridge, your Taser becomes a potent close-quarters tool, allowing you to deliver an immobilizing shock directly through contact. This dual-purpose functionality enhances your defensive options, providing a reliable method for personal protection in various scenarios. Leveraging both modes of operation can significantly boost your confidence and effectiveness in ensuring your safety.

If you enable the share link and change your mind, you can always delete the link, or reset it. This is helpful if the link was shared by someone you don't want in the group. Tap the group chat name, then "Group Link" to change these settings.

When you create a new story, you will always get the above options to choose who can view it. You will also get the option to restrict it to only a specific group chat.

The Taser Pulse, a favored choice among civilians for its compact design and ease of use, offers an effective range of up to 15 feet. While not as extensive as other models, this range strikes a perfect balance for personal protection in close-to-moderate distance scenarios. The Pulse is engineered for those who value the combination of discretion and readiness, ensuring that you have a reliable line of defense against threats without needing to be within arm’s reach. Its 15-foot range is ample for most self-defense situations, providing enough space to make a critical move while maintaining a safe distance from an assailant. Tailored for quick deployment, the Taser Pulse empowers you to respond swiftly and efficiently to protect yourself, demonstrating its prowess as a highly effective tool in your safety arsenal.

Once you've started a message thread, you can consider verifying the authenticity of the person you are talking with to make sure their encryption key wasn't tampered with (a process called key verification ). This may not be necessary for everyone you communicate with, but can be useful in cases where you're talking about private information. The process works the same on both Android and iPhone:

When exploring the realm of civilian Tasers, you’ll find that these empowering self-defense tools have a reach typically spanning from 15 to 30 feet. This variance allows for a flexible approach in maintaining a safe buffer between you and a potential threat. The beauty of this range lies in its balance – close enough to ensure accuracy and effectiveness, yet far enough to provide a moment of safety in stressful situations. Achieving a successful connection with your target is more feasible within this distance, emphasizing the importance of precise aim. Whether navigating a dim parking lot or a secluded walking path, understanding your Taser’s capabilities empowers you to use it to its fullest potential.

Professional police Tasers pack a punch with their impressive range, capable of reaching up to 30 feet accurately. This extended reach gives law enforcement an invaluable advantage, allowing them to manage potentially volatile situations from a safer distance. The design of these professional-grade Tasers takes into account the dynamic environments officers often find themselves in, offering a means to effectively control a suspect without the need for close physical engagement. The extended range not only aids in keeping officers safe but also helps minimize physical confrontations.

Despite the name, Signal's usernames don't work like you may be used to on social media accounts, nor do they work exactly like a phone number. Think of your username more like a "discovery handle." It's a way for people to easily find you, and you can change it as often as you like. By default, after you set up a username, anyone you chat with will not be able to see your phone number unless they already have your number in their phone's address book.

If you use biometrics (like your fingerprint or face) or a PIN to lock your phone, you can also lock down the entire Signal app. This means after unlocking your phone, you'll need to authenticate again to open the app or access chats. To lock the whole app:

Enabling "Registration Lock" prevents your phone number from being registered on a different device without the PIN you set up when you first installed Signal. Make sure you write this PIN down, because without it, you will not be able to get back into your Signal account for at least seven days if you change phones.

Alongside one-on-one chats, Signal also supports group chats and group video calls. Both of these are end-to-end encrypted. Creating a new group works the same on both Android and iOS:

Signal requires a working phone number to set up. While Signal doesn't use SMS, your phone number is used to verify who you are and limit you to one account. By default, your phone number is not visible in your Signal profile unless someone already has that number in their address book. If you do not want to use your primary phone number, Freedom of the Press Foundation has tips for getting a secondary number.

You can also change the length of time before a message disappears in each of your chats. The process is the same on both Android and iPhone:

How far does a Taser shoot? This question must be considered when investing in a less-lethal self-defense weapon. Tasers are popular for incapacitating attackers from a distance, offering individuals a way to protect themselves without resorting to lethal force. This blog post will review the different ranges of Tasers, from civilian models to professional police units, to help you understand how far these devices can reach and how to use them effectively.

Understanding your Taser gun’s capacity for firing is important for effective self-defense. The majority of Taser models are built for a single use per cartridge, necessitating a quick cartridge change to stay ready. This design ensures that each deployment delivers a controlled, high-quality electrical charge to help neutralize a threat efficiently. However, certain models do offer the capability for multiple shots, giving users an advantage in scenarios involving more than one assailant or in case the first shot doesn’t hit its mark. Familiarizing yourself with your device’s specific features, including how many shots it can fire before requiring a reload, is an important step in harnessing its full protective potential. This knowledge enables you to prepare adequately for any situation, ensuring that you’re never caught off guard.

By default, when you view a story, the person who created that story may be able to see that you viewed it. If you don't like the idea of others knowing when you've viewed their stories, you can hide that information. When you do, it will also make it so you cannot see who has viewed your stories:

Some phones give you an option for custom keyboards, but a custom keyboard can leak information to third-parties. On Android, you have the option for an "Incognito keyboard" in Signal that can prevent some keyboards from collecting data, though it is not a guarantee to protect you from a malicious keyboard.

Disappearing messages rules apply to any sort of communication you do in a chat, including text, files, photos, location, GIFs and whatever else. But when you delete a reply to a message, the behavior can be a little different than you may expect.

After an introductory screen with information about the Terms and Privacy Policy, you will see a dialogue explaining why Signal requests the “Contacts” permission on your phone.

On both Android and iPhone, you also have the option on this screen to limit who can find you by your number. By default, this is set to "Everybody," meaning that anyone who has your phone number in their phone's address book will automatically find you on Signal. If you don't want it to work like this, tap "Who can find me by my number?" and change the setting to "Nobody." Unless you also set up a username, nobody will be able to initiate a chat with you if you set this to "Nobody." Once a username is set up, people will only be able to start a chat with you if they have your username.

Signal has a feature called "disappearing messages" which ensures that messages will be removed from your device and the device of your contact(s) in a chat a chosen amount of time after the messages are seen (the countdown starts when the recipient opens the message, not after you send it). While it's a handy feature, remember that those you are chatting with can log or take screenshots of your conversation, even if you’ve enabled disappearing messages. You can set up a default time period for disappearing messages for every new chat you create:

Since Signal treats your phone number like a username, you may need to change it if you get a new number, or if you decide that you want to get a secondary number for communication. You can change your number easily:

You can also optionally create a username to share with others instead of your phone number. We'll get into setting this up below.

By default, you will see certain content in Signal when you open the app switcher. For example, if you switch back and forth between apps while chatting with someone, the app switcher will show the contents of those messages. The main concern here would be if someone happens to look over your shoulder when you switch apps and get a glimpse at your private chats. You can set up Signal so it blocks this view:

When you want to share your username with someone, you can tap [profile picture in the top left] > [box with your name at the top of the screen] > QR Code or Link to share a link or a QR code.

On the next screen, you're asked to create a name for your group, select a duration of time for disappearing messages (more on these below), and then tap "Create." As long as you added at least one person to the group chat, you'll go to the main chat screen.

"Who Can See My Number," controls whether or not your phone number is visible to people (or groups) you message. For example, if set to "Everybody," when you're in a chat with someone, even if you previously only exchanged usernames, they can see your phone number. This is set to "Nobody" by default.

In order to use Signal, the person you are contacting must have Signal installed. But otherwise, using Signal works essentially the same as other chat and phone apps you've used. Alongside text, you can send stickers, photos, voice memos, GIFs, files, and more. All of these are also end-to-end encrypted.

If you cannot access Signal because the service is blocked in your region, you can try using a proxy server. When you connect to a proxy server, you connect to a server set up by volunteers, not Signal, which in some situations can help you use Signal in places where it's blocked. Accessing Signal over a proxy server is straightforward, but in order to find a reliable one you will need to search online. It is usually best to search on social media for proxy details when you're in need of one. To use a proxy server:

If you're in a circumstance where you're calling someone you don't trust (or they're calling you), consider changing how Signal routes your call. By default, Signal uses peer-to-peer calling, which can leak your IP address to the other caller. If that caller is not in your contacts list, Signal defaults to an option that relays the call through their service, hiding your IP address. But you can also enable this for every call, if needed. But note that the increase in privacy comes at the cost of call clarity.

You can also set the permissions of the group chat to restrict people from renaming the group or adding new members. Tap the group chat name, then "Permissions" and change the settings however you prefer.

You can change your username anytime you want without losing the chats and contacts you have already started, but if someone only has your old username and tries to contact you, they will not find you. Note that if someone who you've blocked changes their username, they will continue to be blocked.

Signal can check your contacts list to see who is using Signal. To do this, Signal uses a private contact discovery system. The data uploaded to Signal is immediately deleted after your contacts are matched up. If sharing your contacts with Signal is a concern, you can deny the contacts permission. If you don’t allow this permission, you can still use Signal, but you have to manually enter phone numbers to begin chatting with people. You can change this in the future, but for now, choose to allow or deny access:

This is also a good time to audit any keyboard you've installed in the past and perhaps forgotten about. If you do not need them, use them, or know enough about the keyboard app to feel comfortable using it, it's best to remove it:

If you have no interest in the Stories feature, you can disable Stories entirely. Doing so makes it so you cannot view other's stories, and removes the "Stories" tab from the app's main screen:

"Who Can Find Me By Number," controls whether someone can type your phone number into the search bar to find you, or pull up your phone number through their address book. This is set to "Everybody" by default. If you set it to "Nobody," it makes it so even people who do have your number in their address book will not be able to easily find you on Signal. You will instead have to share your Signal username with them. To change this setting:
