File Storage & Sync — Frequently Asked Questions

Can I keep using Google Drive if my company is based in the EU?
While you can technically use Google Drive in the EU, doing so involves legal risk. Google Drive stores data on US infrastructure subject to the CLOUD Act, meaning US authorities can request access to your files. Several EU data protection authorities have questioned whether Google's data transfers to the US comply with GDPR. Switching to an EU-based file storage provider eliminates this uncertainty entirely.
Does Dropbox Business with EU data residency solve GDPR concerns?
Dropbox Business offers an EU data residency option, but the company itself remains a US entity subject to US law. The CLOUD Act can compel US companies to hand over data regardless of where it is physically stored. A true EU-based file storage provider is incorporated in Europe, meaning US legal instruments have no jurisdiction over your files.
Do I need client-side encryption for GDPR-compliant file storage?
GDPR does not explicitly require client-side encryption, but it does require appropriate technical measures to protect personal data. Client-side (zero-knowledge) encryption is the strongest guarantee because even the storage provider cannot read your files. For sensitive data like HR records, medical files, or legal documents, client-side encryption provides an additional layer of protection that significantly reduces your risk in the event of a data breach.
