Frequently Asked Questions

How does Cosmic Proton support unlimited storage?

Cosmic Proton uses a decentralized storage method. By converting massive files into secure, encrypted segment chunks, the platform leverages secure, globally-backed public cloud infrastructure to store data. This guarantees that you enjoy unlimited storage capacity with zero hosting overhead.

Are my files kept completely private?

Yes. All encryption is performed locally on your client machine before any bytes are transmitted to the cloud. The system implements a robust zero-knowledge AES-256 standard. Only the holder of the secure link has the ability to view or decrypt the files, keeping them completely safe from prying eyes.

Does this cost anything to maintain?

No, it is entirely free. Both the decentralized storage servers and the Cloudflare Pages serverless edge network feature massive, highly generous free tiers. You can stream, download, and store files daily without ever incurring a single fee.

Can I stream media files directly?

Absolutely. The platform integrates a modern web media pipeline that compiles video chunks into adaptive HD streaming manifests on-the-fly. Watch full-length, high-definition videos, listen to progressive audio files, or scroll through massive photo galleries directly in the browser.
