More and more people (and organizations) are using the cloud to keep personal data secure. This often includes sensitive personal data.
Dropbox is not the most secure provider out there and its privacy policies leave much to be desired.
Choose a reliable cloud service below that is proven to respect your privacy.
Tresorit is a cloud service from Switzerland. It is mainly focused on (business) collaboration.
Using end-to-end encryption, Tresorit encrypts every file including metadata on your devices with unique randomly generated encryption keys. These keys are never sent unencrypted to Tresorit’s servers. Access to files is only possible with a user’s unique decryption key.
Tresorit also offers a good WeTransfer alternative. With Tresorit Send, it is possible to send large files very securely.
Tresorit is a bit more expensive than the above options, but you get a secure cloud service in return.
Nextcloud is the best option for those interested in hosting their cloud files themselves. Hosting a cloud server yourself is obviously the best choice in terms of privacy.

Nextcloud is open source software.
You can also use storage from several reliable NextCloud partners, you often get a few Gb for free.
