If you are worried about the protection of your personal data and your security on the internet just leave the application.
Below are some alternatives that will work perfectly to talk to your own. Of course they can also be used for business purposes if the budget is low.
FaceTime on iPhone, iPad and Mac
FaceTime is Apple's proprietary voice and video calling service. Is available to anyone with an iPhone, iPad or Mac. You cannot use FaceTime if you do not have an Apple device.
This application is known for its ease of use for one-on-one communication and small group chats. However, the service has expanded in recent years and now supports up to 32 people in one call. Unfortunately, the proprietary nature of the FaceTime application means that users on Android and Windows devices cannot participate.
The well-known Skype.
Skype is the most obvious alternative to FaceTime as it comes pre-installed with Windows 10. It also works with your Microsoft account. The big difference here is that, although the application is now owned by Microsoft, Skype is not limited to Windows devices.
Video, voice and text application is available on all major platforms: iOS, Android, macOS, even Linux.
Skype is not just a voice and video application. You can use it to send files, as a real-time translator or as a means to share your location with friends. You can also use it to call international numbers (for a fee), as a voicemail service or to forward your calls.
Skype has been offering end-to-end encryption in private chats since 2018, but the feature is opt-in. You will need to click or tap "Start New Private Chat" to use this feature. Normal video calls are encrypted, but do not use the same end-to-end encryption as other services, such as FaceTime and Duo.
Another option is Skype Meet Now, which you can use even if you are not registered with Skype or Microsoft. You can use it with Skype desktop client or online if you use Microsoft Edge or Google Chrome.
Google Duo is a video calling application for Android and iOS. There is also an online version available for anyone on the desktop. It supports up to eight participants in one call, a number that should be enough to keep in touch with your close friends and family.
What makes the Duo app unique is the call quality it offers. In the Play Store, Google describes it as a "high quality video calling application." If you have a reliable internet connection the Duo is worth a try. Just remember, the video will be as good as your camera and connection allow.
The open Jitsi
Jitsi is a free open source application owned by 8 × 8. The company uses this technology in its top products. You can download the application and install it on your own server, or alternatively, you can use the Jitsi Meet version.
The service is available via the web or you can use the iOS and Android mobile applications. The application has many features and the number of participants you can have in one call is (theoretically) unlimited.
In addition to group video chats, Jitsi also supports screen sharing, YouTube streaming, telephone connectivity, and YouTube-wide video streaming. You can also integrate Jitsi into Slack and use it to communicate with your team or customers.
Δυστυχώς, η Jitsi δεν υποστηρίζει πλήρη end to end κρυπτογράφηση. Όπως η Zoom, το βίντεο που αποστέλλεται στο διακομιστή κρυπτογραφείται, αποκρυπτογραφείται και στη συνέχεια επανακρυπτογραφείται όταν μεταδίδεται στους άλλους συμμετέχοντες. Αυτό σημαίνει ότι someone with access to the server could possibly see your conversations. But if you install Jitsi on your own server, there is no problem.
Google has Hangouts Meet as part of its Business Suite G Suite tools. It is a powerful video conferencing solution if you have the budget to support it. For those who do not have the money, there is classic version του Google Hangouts που εξακολουθεί να είναι διαθέσιμη δωρεάν και υποστηρίζει έως και 10 άτομα σε μια κλήση βίντεο αντί της Zoom.
Hangouts is available through the web and exclusive apps for Android and iOS.
The service does not have the end-to-end encryption of FaceTime and Duo. Encrypts videos and messages between your devices and Google servers, but they are decrypted on the server. This means that one may be able to see them.
Εάν χρησιμοποιείτε ήδη το Slack για να είστε σε επαφή με τους συναδέλφους σας, μπορείτε να το χρησιμοποιήσετε και για τη διεξαγωγή κλήσεων φωνής και βίντεο αντί της Zoom. Αν εγγραφείτε στο Standard plan ή κάποιο ακριβότερο, μπορείτε να πραγματοποιείτε ομαδικές βιντεοκλήσεις που μπορούν να συμπεριλαμβάνουν μέχρι και 15 άτομα.
Slack is available via the web, and exclusive applications for Windows, Mac or Linux or for mobile applications for Android and iOS.
Like many other services, Slack does not use end-to-end encryption.
Is answer Microsoft in Slack. You can invite an unlimited number of people to your free account. Microsoft describes the application as a "free group voice or video calling application."
The company has not clarified the limitations of the Microsoft Teams platform, but it seems that the biggest obstacle is the ability to schedule online meetings. Regardless of the version you are using (free or not), only four streaming videos are displayed at a time, regardless of who is connected.
Microsoft Teams does not use end-to-end encryption, according to the company, they are encrypted "during transport and storage".
It's like Slack, but for communities and friends, with a focus on the game. Discord supports private video calling for up to 10 participants.
Discord it's free, but there is also an optional Nitro package of $ 4,99 per month. But if you just want to use the service with audio features and limited phone calling, you do not have to pay anything.
Discord uses limited encryption, not the most powerful end-to-end. If you are concerned, however, you can use the informal Tampermonkey Encord End-to-End Encryption script (it only works in your browser application).
Snap Camera is not an exclusive video calling application, but it can add a lot to existing applications.
As the name suggests, the Snap camera owned by Snapchat. Αφού εγκαταστήσετε την εφαρμογή στον υπολογιστή σας Windows ή Mac, μπορείτε να χρησιμοποιήσετε τα φίλτρα του Snapchat στις εφαρμογές Skype, Google Hangouts, Google Meet και, φυσικά, την Zoom. In addition to the existing filters, you can also create your own.
