Lesson: Here you will get to know safe and trustworthy providers of email, contacts and calendars

The use of e-mail has become less important due to social networks and instant messengers (e.g. Signal or Telegram). Nevertheless, in many public and private situations it is essential to have an e-mail address, contact details and a calendar.

And even if e-mail providers such as Google or Microsoft are user-friendly and very popular, it is more the small, specialized providers where your data (even regardless of encryption) is in good and safe hands.

These providers:

  • see us as customers and not as products
  • do not have our e-mails searched by algorithms for advertising purposes
  • only work together with investigating authorities if there is a given reason (e.g. a court order).
  • are pioneers who provide an infrastructure that is privacy-oriented and can also bypass data retention without cause

The two trustworthy providers I presented offer not only e-mail but also contact data maintenance and calendar management. You can keep this data in sync between all devices.
