Applying information technology to teaching will create high interaction between teachers and students, stimulate observation and develop thinking for children. At the same time, it helps teachers save a lot of time preparing teaching materials, promoting many creative ideas in teaching.
What information does WhatsApp collect?
WhatsApp collects the initial information that users provide to use it, including names, phone numbers, email addresses, and even contacts. These are required to use the service.
Usage data is also collected to calculate the metrics. These data include performance logs, like how often you’re logged in and how often.
Remember: WhatsApp is a business, so WhatsApp will use this information (for example, 58% of users visit the app multiple times per day) to improve the app and drive its own success. .
These are also the reasons why WhatsApp “sucks up” data about the device you use, like the model, operating system, battery level and version of the application you are running, as well as connection details such as home network operator, IP address and signal strength.
The WhatsApp website also reconciles information across persistent cookies (cookies that are stored until the user actively deletes them) and session cookies (cookies stored in the cache). Persistent cookies make the page load faster if you come back in the future, and session cookies are deleted after you close your browser.
Does WhatsApp share your data?
In some cases, WhatsApp will share user information, although of course it is limited to the aforementioned collected data. WhatsApp claims to be purely a service, including marketing (marketing), security, and customization.
WhatsApp allows ads to appear. However, they are used by businesses and some of them can access your contact details. These companies may send you receipts, shipping information, and reminders. WhatsApp then provides feedback analytics, helping these companies better understand communication performance.
You may note that the amount of data collected has increased, especially since Facebook acquired WhatsApp.
WhatsApp is part of the Facebook family, meaning that data is shared between this SMS app and its parent company. Information collected from WhatsApp is not publicly available, instead, they are added to Facebook’s hidden profile about you. This remains one of WhatsApp’s biggest security concerns.
This does not mean that other services do not collect your information. For example, Google logs app usage through its Web and App Activity feature, so if you’re on Android, you don’t just have to worry about WhatsApp (only if you enable Web and App Activity, of course. App Activity).
Does WhatsApp store messages?
No, WhatsApp usually doesn’t keep your messages. This is a big plus and is what users expect from an app like this.
WhatsApp uses encryption to send messages between devices, over WhatsApp servers. Once the message is sent, it is automatically deleted from the WhatsApp server. Information removed from the server includes chats, photos, videos, voice messages, files, and location information you share with your contacts.
Encryption ensures that only you and the person you’re communicating with can read the message. It is also not possible for third parties and WhatsApp itself to know what you are communicating. Therefore, the security concern lies with the device itself, where your conversation history is kept.
However, messages can sometimes remain on WhatsApp servers if not delivered. After 30 days, WhatsApp will delete them.
Why is a message not sent? This happens if you or the recipient has been offline for a long time, you are blocked (which happens rarely), or if the recipient is no longer using WhatsApp.
Learn about the “About” section in WhatsApp
You may have noticed that WhatsApp has a section named “About”. But is this a privacy concern? After all, you don’t want too much personal information to be revealed.
Fear not, this section contains no sensitive data. It contains only short messages that other users can see under your name. Some people write a joke or a quote to let others know they have added the correct contact number. However, in most cases, it makes sense to let people know that you are using WhatsApp. Very few users change this.
But if you want to change it, click Settings at the bottom right of the screen, then click your name. Click the About section. You are given a lot of options, including Busy, Battery about to die and In a meeting. You can find options in
