📌 Introduction: Why cloud data protection is crucial today
Cloud services have become an integral part of everyday digital life. Whether for backups, file sharing, teamwork or calendars - the cloud is convenient, but often also a data protection risk. Many providers such as Google Drive, Dropbox and OneDrive store data on US servers, automatically analyze content and link it to other services. This is a problem for users who take their digital sovereignty seriously.
Data protection-friendly cloud services offer an alternative: they consistently encrypt data, store it on European servers and do not track it. In this article, you will find out how to use cloud services in a privacy-friendly way - with specific recommendations, practical settings and a look at the best providers.
🔍 What makes a cloud data protection-friendly?
A cloud service is data protection-friendly if it:
- End-to-end encryption offers - ideally on the client side
- Server locations in the EU or Switzerland has
- Open source or transparently documented is
- No data transfer to third parties allowed
- No analysis of your content carries out
- No connection to big tech companies has
In addition, the service should GDPR-compliant and give you control over your data - including deletion options, access control and a backup function.
⚠️ The problems with classic cloud services
Google Drive
- Content is analyzed automatically
- Link to Gmail, calendar, YouTube
- US server, no zero knowledge
Dropbox
- Metadata is saved
- No complete protection against access by authorities
- Partially unencrypted synchronization
Microsoft OneDrive
- Linking with Windows and Office
- Content can be used to improve services
- US Cloud Act applies to requests from authorities
These services are functionally strong - but Not suitable for sensitive or private data.
