A push notification is a message that appears on your device without you opening an app or website
When an app or website sends you a push notification, it shows up on your phone, tablet, or computer screen — even if you are not using that app at that moment. The message pops up, buzzes, or vibrates to get your attention. Unlike email, which you have to check, or text messages that come through your phone's messaging system, push notifications are controlled by individual apps and websites. They bypass your normal inbox and land directly on your screen.
Push notifications work because apps and websites ask your permission when you first install or visit them. You see a prompt asking "Allow notifications?" If you tap yes, that app gets the ability to send you messages whenever it wants — unless you change your mind later. The notification travels from the app's servers to your device through what is called a push notification service. On iPhones, Apple runs this service. On Android phones, Google runs it. On computers, the browser (Chrome, Firefox, Safari) handles it.
The word "push" means the message is sent to you rather than pulled by you. You do not have to ask for it or check for it. It arrives uninvited, which is why push notifications can feel intrusive — and why controlling them matters.
Key Takeaways
- Push notifications are messages sent directly to your device by apps and websites, appearing on your screen without you opening the app.
- Apps ask for permission to send notifications when you first install them, and you can change that permission at any time in your device settings.
- Different apps send notifications for different reasons: some alert you to urgent information, others remind you to use the app, and some exist mainly to drive engagement.
- Turning off notifications from an app does not delete the app or prevent it from working — it only stops the pop-up messages.
- You can control notifications at three levels: turn them off entirely for an app, silence them without deleting them, or allow only certain types.
Why apps and websites want to send you notifications
Apps send push notifications for three main reasons, and understanding which one applies helps you decide whether to allow them. Some notifications are genuinely useful: a banking app alerting you to unusual activity, a weather app warning of a storm, a calendar app reminding you of an appointment. These notifications give you information you might actually need.
Other notifications are reminders designed to pull you back into the app. A social media app might notify you that someone liked your post, or a fitness app might remind you that you have not logged your workout today. These are not emergencies — they are nudges meant to keep you engaged and using the app more often.
A third category exists purely to drive business. A shopping app sends notifications about sales. A news app sends notifications about trending stories. A game sends notifications saying your energy has recharged. These notifications benefit the company, not you. They are designed to interrupt your day and pull your attention toward their product.
Most apps mix all three types. A messaging app sends you notifications about actual messages (useful), reminds you to check the app (engagement), and notifies you about new features or promotions (business). Knowing which notifications fall into which category helps you decide what to keep and what to turn off.
How push notifications differ from other types of messages
Push notifications are different from text messages, emails, and in-app messages, and the difference matters for how you control them. A text message goes through your phone's messaging system and appears in your Messages app. An email goes to your email inbox. Both of those are standard communication channels that you check on your own schedule. A push notification bypasses all of that — it interrupts you directly on your home screen or lock screen.
In-app notifications are messages that appear only when you are already using an app. They might pop up as a banner at the top of the screen or a dialog box in the middle. You see them because you are already there. Push notifications are different because they reach you when you are not using the app at all — when you are looking at your home screen, using a different app, or not using your phone.
This distinction matters because push notifications are harder to ignore. They are designed to interrupt. Email and text messages sit in a folder until you check them. Push notifications demand your attention right now. That is why they are more powerful for companies trying to drive engagement, and why controlling them is more important for your own focus and peace of mind.
Where push notifications appear on different devices
On an iPhone, push notifications appear as banners at the top of the screen, or as badges (small red circles with numbers) on the app icon, or both. You can also see them in your Notification Center, which you access by swiping down from the top. On an Android phone, notifications appear as cards that slide down from the top of the screen and also collect in your notification shade, which you access by swiping down from the top.
On a Mac or Windows computer, notifications appear as small boxes in the corner of your screen — usually the bottom right on Windows, the top right on Mac. They disappear after a few seconds unless you click them. On a web browser, notifications appear as small pop-ups or banners, and they are controlled separately from your device notifications. A website can send you browser notifications even if you have turned off notifications for other apps.
The location matters because it affects how straightforward they are to ignore. A notification that appears on your lock screen interrupts you even if you are not using your phone. A notification that appears only in your notification shade requires you to swipe down to see it, which is slightly less intrusive. Understanding where notifications appear on your specific device helps you decide which ones are worth allowing.
The permission system: how apps ask and how you can change your answer
When you first install an app or visit a website, it asks for permission to send you notifications. On iPhone, you see a dialog box asking "Allow [App Name] to send you notifications?" You can tap "Allow" or "Don't Allow." On Android, the permission system works similarly, though the exact wording varies by app. On a web browser, you see a prompt asking if you want to allow notifications from that website.
The key thing to know is that your answer is not permanent. You can change it at any time. If you tapped "Don't Allow" and later want to receive notifications, you can go into your device settings and turn them on. If you tapped "Allow" and now regret it, you can turn them off the same way. You do not have to uninstall the app or do anything drastic — you just change the permission.
On iPhone, go to Settings, scroll to the app name, tap it, and look for Notifications. You will see a toggle for "Allow Notifications." On Android, go to Settings, find Apps or process Manager, select the app, tap Notifications, and toggle them off. On a computer, the process varies by browser and website, but most browsers let you manage notification permissions in their settings under Privacy or Notifications.
Many people do not realize they can change these permissions, so they live with notifications they do not want. Others say yes to everything and then feel overwhelmed. The permission system exists to give you control — you just have to use it.
What happens when you turn off notifications from an app
Turning off notifications does not break the app or prevent it from working. The app continues to function normally. You can still open it, use it, and receive information from it. The only thing that changes is that you will not see pop-up messages on your screen. If the app has new information — a message, an update, a reminder — you will see it when you open the app, but you will not be interrupted by a notification about it.
Some apps show a small badge (a number or dot) on their icon even when notifications are turned off. This badge tells you that something new has happened in the app. You can usually turn off badges separately from notifications, though the option varies by app and device. On iPhone, go to the app's notification settings and look for "Badge App Icon." On Android, look for "Show notifications" or "Badge" in the app's notification settings.
Turning off notifications is not the same as silencing them. Silencing means the notification still arrives, but it does not make a sound or vibrate — it just sits quietly in your notification shade. You can silence notifications from an app while still allowing them to appear on your screen. This is useful if you want to see notifications when you check your phone, but do not want them interrupting you with sounds and vibrations.
Why some notifications matter more than others
Not all notifications are equally important. A notification from your bank about a large withdrawal is urgent. A notification from a social media app that someone liked your post is not. Learning to distinguish between them helps you decide which apps deserve notification permission and which do not.
Ask yourself: would I want to know about this right now, or can it wait until I open the app? If a notification is about something time-sensitive or important to your safety or finances, it probably deserves to interrupt you. If it is about engagement or sales or trending content, it probably does not. If you are unsure, you can always turn notifications on for a week and see how you feel. If they are annoying, turn them off. You can always turn them back on later.
Some apps let you choose which types of notifications to receive. A messaging app might let you turn off notifications about new group chats but keep notifications about direct messages. A news app might let you turn off notifications about entertainment but keep notifications about breaking news. If an app offers these options, take advantage of them. You do not have to choose between all notifications or none.
Frequently Asked Questions
Can someone send me a push notification if I did not give them permission?
No. Only apps and websites you have explicitly allowed can send you push notifications. If you see a notification from an app, it means you said yes to notifications from that app at some point. You can revoke that permission at any time in your device settings.
Do push notifications use my data or battery?
Push notifications use a small amount of data and battery, but not enough to notice in most cases. The impact is minimal compared to using the app itself. If you are trying to save battery or data, turning off notifications will help slightly, but closing unused apps or reducing screen brightness will make a bigger difference.
What is the difference between a notification and an alert?
An alert is a type of notification that demands your when ready attention — it usually requires you to tap a button to dismiss it. A regular notification appears on your screen but does not require action. You can usually choose which type an app uses in its notification settings.
If I turn off notifications, will the app still work?
Yes. Turning off notifications only stops the pop-up messages. The app itself works exactly the same way. You can still open it, use all its features, and see new information when you open it — you just will not be interrupted by notifications when you are not using the app.
Why do some apps keep asking for notification permission even after I said no?
Some apps are designed to ask again after a certain amount of time, hoping you will change your mind. This is intentional — the app developers want you to enable notifications. You can keep saying no, and the app will continue to work. If the repeated requests bother you, you can uninstall the app or leave a review mentioning the behavior.
