Yes. When upgrading, your new limits apply instantly and billing is prorated. When downgrading, changes take effect at the start of your next billing cycle.

Your files remain completely secure in your account. If your total storage exceeds your new plan's limit, your API keys will temporarily pause new uploads, but you will retain full read and download access to all existing files.

Storage quotas are hard limits on total retained payload size. FREE includes 2GB, PRO LITE uses 20GB, PRO provides 32GB, and ENTERPRISE handles custom capacities. You can track your real-time usage via the dashboard.

We support virtually all modern file types including images (JPG, PNG, WebP, SVG), documents (PDF, DOCX), videos (MP4, WebM), audio, and JSON payloads. The maximum file size limit scales automatically with your chosen pricing tier.

All files are encrypted at rest using AES-256 and in transit via TLS. For maximum privacy, we employ a strict zero-knowledge architecture, meaning we have absolutely no access to your actual file contents or payload data.

We do not offer a refund policy for paid subscriptions. If Null Drop doesn't meet your development or business needs, simply contact our support team within the first 14 days for a full, no-questions-asked refund.
