關於 VirtualDrive 的常見問題

VirtualDrive offers significantly cheaper paid storage tiers (2 TB at $9.99 vs Dropbox Plus at $11.99 for the same) while including encryption and audit logs at every level. The free tier is also larger than Dropbox's (2 GB) and Google's (15 GB shared across all Google services). We do not scan files for advertising, we do not train AI on user content, and files are stored with Cloudflare R2 and Amazon S3, whose data centers are SOC 2 Type II audited.

Yes. Free: up to 500 MB per file; Pro and Ultra: up to 5 GB per file. The same limit applies on the web, iOS, and Android. There are no per-day upload caps on the standard tiers beyond the daily traffic limits described in your plan.

Every file you upload counts toward your quota — both your personal drive and shared workspace content you own. Files in Trash continue to count until you empty the Trash — nothing in Trash is removed automatically. Files shared with you by other users count toward their quota, not yours.

Yes. Pro yearly includes a 7-day free trial for accounts that have not subscribed before. The Free plan is not a trial — it doesn't expire, and you keep 20 GB and the full feature set. Cancel a paid plan at any time from your account settings, and you keep access until the end of the billing period.

Your files are private by default, and staff access is restricted. Files are encrypted in transit (TLS) and at rest (server-side AES-256 by our storage provider). VirtualDrive is not end-to-end encrypted, so access is controlled by policy rather than made technically impossible: staff have no operational reason to read user content and our access policies prohibit it except where required to keep the service safe or comply with the law. We do not automatically scan the contents of your files. Shared links that people report to us are reviewed, and child sexual abuse material is reported to NCMEC as required by 18 U.S.C. §2258A.

No. The Privacy Policy explicitly forbids using customer files for AI training, model fine-tuning, recommendation engines, or sale to third parties. We process your files only to deliver the service you signed up for: storage, retrieval, sharing, and the search you initiate.

VirtualDrive is not currently offered as a HIPAA-compliant service. The infrastructure (encryption, audit logs, access controls) meets most of HIPAA's technical safeguards, but we do not sign Business Associate Agreements at this time. If HIPAA compliance is a hard requirement for your team, please contact support@virtualdrive.us to discuss enterprise options.

Yes. We honor the data subject rights granted by GDPR (EU/UK) and CCPA (California) including access, correction, deletion, portability, and opt-out of sale (we do not sell data). To exercise these rights, email support@virtualdrive.us. We respond within 30 days. Full text in the Privacy Policy.

We would give every active user at least 30 days notice and direct download access to all their files during that window. Files are stored as ordinary files in standard cloud storage — there is no proprietary container format you'd need our software to read.

Yes. Create a workspace, invite teammates by email, and assign roles (owner, admin, member, viewer). Files in a workspace are visible to everyone with access; permission grants cascade down folder trees. Storage costs stay predictable for larger teams.

Yes. Failed password attempts are rate-limited per share link and per IP. After repeated failures, the link is locked and the owner is notified. Engineering deep-dive in our blog post on share-link brute-force protection.

PayPal on the web, Apple In-App Purchase on iOS and Google Play Billing on Android. Web subscriptions and app-store subscriptions are billed separately and at different rates (the stores' platform fees). Cancel anytime from your account settings or, for Apple and Google Play subscriptions, from your device's Subscriptions screen.

Apple charges a fee on every in-app purchase, so subscriptions bought in the iOS app cost more: Pro is $12.99/mo in the app and $9.99/mo on the web, Ultra $24.99/mo and $19.99/mo (US prices; App Store prices vary by country). The storage and features are exactly the same, and your plan works on every device you sign in on. App Store subscriptions are billed and cancelled through your Apple ID.

Open Settings → Billing in your account and click Cancel. Your plan stays active until the end of the billing period — you don't lose access immediately. If you subscribed through Apple, manage cancellation from Settings → Apple ID → Subscriptions on your iOS device.

We offer prorated refunds within 7 days of the most recent charge for first-time subscribers. After that, you can cancel future renewals but the current period is non-refundable. Apple IAP refunds are handled by Apple directly. Email support@virtualdrive.us with your account email and we'll process eligible refunds within 3 business days.

Yes. Select any folder (or all files), choose Download, and the app builds a single .zip on the fly streamed directly from storage. There is no size cap on the export. For very large drives, export folder-by-folder to keep the ZIP under your browser's reasonable download size.

A developer API is on our roadmap but is not yet public. If you need early access for an integration, contact support@virtualdrive.us and describe your use case.
