Tresorit is fully GDPR compliant and headquartered in Switzerland, which has an EU adequacy decision. Your files are encrypted on your device before upload, and Tresorit never holds the keys to decrypt them. Because they cannot access the encrypted content, they fall outside the scope of data processor audits for personal data stored in files.
