# Privacy & Ownership

Neutron is built around one core principle: **your knowledge, your rules**.

Whether you're an individual, a startup, or an enterprise, Neutron ensures that your data remains private, secure, and fully under your control. Blockchain-based verification is available when needed but never required.

***

#### End-to-End Privacy by Design

Neutron prioritizes security from the ground up:

* **Client-Side Encryption**\
  All sensitive data is encrypted on your device before it is ever transmitted or stored.
* **No Plaintext Storage**\
  Neutron never stores or reads unencrypted content, whether offchain or onchain.
* **Selective Indexing**\
  You decide which files, messages, and folders are included in your knowledge base.
* **Hash-Based Verification System**\
  Content can be verified cryptographically using secure cryptographic hashes.

Even when documents are stored onchain, only the owner holds the decryption keys. The content remains entirely private.

***

#### Blockchain Ownership

When you choose to store Seeds or documents onchain, Neutron uses blockchain-backed infrastructure to provide:

* Cryptographic proof of ownership
* Tamper-resistant hashes and timestamps
* Full audit trails without exposing content
* Verifiable integrity of every registered document

> Onchain storage runs on **Vanar Chain**.

What you can store:

* Encrypted document references and metadata
* AI embeddings (up to 65KB per document)
* Ownership permissions
* Registration history and access logs

***

#### Transparency Without Exposure

Neutron delivers verifiability without compromising privacy:

* **Explainable AI Responses**\
  You can always see which documents contributed to an answer.
* **Source Citations**\
  Jump directly to the original Seed or file when needed.
* **Immutable Context**\
  Blockchain records confirm content integrity after submission.

Even when AI uses your documents to generate insights, no one else can access the source content unless you authorize it.

***

#### Decentralized Safeguards

Optional onchain features provide additional resilience and accessibility:

* **No single point of failure**\
  Your data is validated and stored across a distributed system.
* **Censorship resistance**\
  No centralized authority can block, change, or hide your knowledge.
* **Global access**\
  Retrieve your encrypted documents from anywhere in the world.
* **Future-proof storage**\
  Blockchain records persist over time with full cryptographic history.

***

#### Enterprise-Grade Controls

Neutron offers powerful tools for organizations that need strict access policies:

* **Role-based permissions**\
  Assign access rights based on team roles or departments.
* **Multi-signature approvals**\
  Require multiple confirmations for sensitive actions.
* **Usage tracking**\
  Log activity like searches, access, and document exports.
* **Recovery and portability**\
  Export or back up encrypted data at any time with full control.
