Frequently Asked Questions

How can I get more free cloud storage?

Using multiple services gives you the most free storage: 15GB Google Drive + 5GB iCloud + 5GB OneDrive + 2GB Dropbox = 27GB total free storage across providers. Store different types of files on different services — documents on Google Drive, iPhone backups on iCloud.

Is Google Drive safe for sensitive files?

Google Drive uses encryption at rest and in transit. However, Google scans files for policy violations and can access data under legal compulsion. For truly sensitive files, use Proton Drive (encrypted, Switzerland-based) or a local backup. For most everyday documents, Google Drive is safe.

How much cloud storage do most people need?

For documents, spreadsheets, and PDFs: Google Drive's 15GB is sufficient for most people. For photo backups: even 15GB fills within 1-2 years of phone photography. Consider Google Photos with Backup & Sync turned off in Drive, or use Amazon Photos (unlimited free photo storage for Prime members).
