Is Calibre Safe to Use?

Fans of reading books should be happy with the development of electronic technology. After all, today one small tablet can contain millions of documents. These can be magazines, newspapers, and, of course, full-length books. But with the development of technology, there are several problems that each user needs to solve independently.

Did you hear about the dangers of MediaFire? It’s not a safe system, and you should stop using it.

First, the collection of many books can simply be confusing. As a rule, file names are written in the Latin alphabet. It is complicated to find the right book in your archive. Secondly, there is no universal format that is supported by all devices. Therefore, books must be converted to the format that your device understands.

Calibre solves both problems at once. This is a kind of database of different books published around the world. And here there is a converter that can help out when you have an old smartphone that only supports a certain format.

In a short time, Calibre has gained worldwide popularity. However, few people have considered whether Calibre is safe to use or not. Let’s look at it in this article.

Calibre’s technical side

The Calibre program is based on open-source code. The program’s source code is publicly available, and anyone interested can view, make changes or distribute the code. For example, you can find it on GitHub.

If you think that such openness can be harmful, then you are wrong. On the contrary, any change that is made from outside is checked by the program’s team of specialists. After a step-by-step check, it is decided whether to make changes or not. In addition, the developers of the program hold open forums where they discuss innovations in the system.

So, anyone who notices a flaw in the technical part can easily report it. And most likely it will be fixed, thereby improving the program.

As a rule, commercial programs do not allow outsiders to interfere with the work of the final product. However, in this case, on the contrary, it helps to make the program more perfect and secure.

Is Calibre safe?

The program developers have publicly stated that Calibre does not store or transmit the personal information of users. However, the program still saves the IP address, the version of the program you downloaded, as well as your operating system.

In addition, the program saves an anonymous search history of current news. After that, the collected data is published on the main page in the form of statistics. According to the official version, this is necessary to configure the program as suitable as possible for each user and make sure that everything works smoothly and without bugs.

Another point is the fact that the program scans your device the first time you connect it. It checks all previously saved books and media files. As the developers say, this is necessary for quick verification of existing data that will not need to be downloaded. However, do not forget that your personal data is also checked and stored.

The most insecure point is the ability to share your library via email. This can be done in two ways: by direct mail or through an electronic intermediary service.

As a rule, this method is considered the most insecure since messages can be intercepted, and the email box can be hacked. This way, the hacker can get all the personal data.

Even though Calibre is a truly multifunctional program that simplifies reading books for millions of people, it is not safe to use. As well as similar programs, it collects and stores user data and has access to the user’s email.
