How to send large files securely using QuantC?

Upload your files on QuantC, set a secure key phrase, and receive a unique 6-character retrieval code. Share the code with your recipient - they decrypt and download with the same key phrase. No account needed.

Is QuantC free and truly anonymous?

Yes. QuantC is completely free and requires no registration. No user tracking, no personal data storage, no activity logs.

How does QuantC protect my files?

QuantC uses AES-256 GCM encryption performed entirely in your browser. Files are fragmented and encrypted before upload. Without the correct key phrase, decryption is computationally infeasible.

What makes QuantC different from other file sharing platforms?

QuantC uses zero-knowledge architecture - the server never has access to your files or encryption keys. Combined with no-account transfers and 1GB+ file support, it is one of the most private file sharing tools available.

Disclaimer

Last Updated: August 14, 2026

Please read this important disclaimer regarding liability, data responsibility, and the use of QuantC. By using our platform, you acknowledge and agree to the following terms.

1. "As Is" and "As Available" Service

QuantC is provided on an "as is" and "as available" basis without any warranties of any kind, either express or implied. We do not guarantee uninterrupted access, continuous availability, or error-free operation of the platform. Your use of the service is entirely at your own risk.

2. No Liability for Data Loss

QuantC operates entirely on a volatile, ephemeral storage model. Files are stored temporarily and are automatically purged after 48 hours. However, data may be deleted earlier in the event of server maintenance, instability, or capacity limits. QuantC is not responsible for any loss of data, failure of transfer, or data corruption. Always maintain secure backups of your important files.

3. Zero-Knowledge Cryptography

Because QuantC utilizes end-to-end AES-256-GCM encryption where the decryption keys are generated and kept exclusively in your browser, we cannot recover your files if you lose your key phrase. It is your sole responsibility to securely communicate the decryption key to your intended recipient.

4. No Liability for Misuse or Unlawful Content

QuantC provides a neutral, encrypted file-transfer tool. We do not monitor, endorse, verify, or have access to the contents of the files shared through our platform. Users are solely responsible for the legality of the data they transfer. QuantC and its creators disclaim all liability for any damages, legal repercussions, copyright infringement, or illegal activities conducted by users utilizing this service.

5. Third-Party Infrastructure

Our service relies on third-party infrastructure providers (e.g., Cloudinary, MongoDB Atlas) for encrypted data storage and routing. While we ensure all data is client-side encrypted before transmission, QuantC is not liable for any outages, breaches, or failures originating from these third-party services.

6. Regulatory Compliance

QuantC is designed to comply with applicable Indian laws, including the Digital Personal Data Protection (DPDP) Act, 2023, and the Information Technology Act, 2000. However, we make no representations that the platform is appropriate or available for use in other jurisdictions. Users accessing QuantC from outside India do so at their own volition and are responsible for compliance with their local laws.
