Privacy Policy & Data Security.

Last Updated: August 5, 2026 | Effective Date: Immediately

Architectural Zero-Knowledge Privacy

At Nextgen Astra, privacy is not a promised policy—it is enforced directly by software architecture. None of your uploaded files, password strings, JSON data, PDF documents, or health metrics ever touch a remote backend server. All computations execute locally in your web browser sandbox using JavaScript and WebAssembly (WASM).

1. Zero Server File Processing & Client-Side Execution

When you perform an operation on Nextgen Astra—such as compressing an image, converting a PDF, generating a password, decoding a JWT, or calculating health statistics—the operation is performed entirely inside your device's browser memory (V8 / JavaScript Engine).

  • No Remote Processing: Files are read directly from your local filesystem using browser HTML5 APIs (FileReader, Blob).
  • Zero Storage Queues: No temporary buffers, server disks, or cloud storage buckets exist in our infrastructure.
  • Offline Capability: Once loaded, pages operate air-gapped without needing internet access.

2. Local Browser Storage & RAM Memory Policy

To provide features like user theme preferences (light mode or dark mode persistence), Nextgen Astra may read or write tiny non-sensitive state tokens in your browser's localStorage.

These stored preference values contain zero personal identification, zero email addresses, zero file fragments, and zero user telemetry. Closing your browser tab immediately frees any processing RAM allocated during document or calculation operations.

3. Third-Party Analytics & Advertising Policy

Nextgen Astra operates without intrusive telemetry scripts, keyloggers, screen recording trackers, or session playback engines. We do not sell, rent, monetize, or transmit your personal data to ad brokers or data aggregators.

If standard privacy-focused aggregate metrics (such as page view counts) are collected via static hosting providers, they are entirely anonymized and decoupled from user identities or document payloads.

4. Cryptographic Security Architecture

Our tools enforce security at the browser API level:

  • Cryptographic Randomness: Secure utilities (like Password Generator) utilize the native browser crypto.getRandomValues() API for hardware entropy.
  • WASM Memory Safety: Heavy computations run within sandboxed WebAssembly modules isolated from cross-origin access.
  • HTTPS Encryption: All static site assets are delivered strictly over HTTP Strict Transport Security (HSTS) compliant HTTPS connections.

5. Global Regulatory Compliance (GDPR, CCPA, HIPAA)

Because Nextgen Astra never collects, transmits, or retains personal data, confidential files, or health records on remote servers:

  • EU GDPR Compliance: No Data Subject Access Requests (DSAR) or erasure requests are needed because zero user data is stored remotely.
  • US CCPA Compliance: We do not sell or share consumer personal information.
  • HIPAA Alignment: Document utilities can process sensitive medical records without breach risk because files remain strictly on the user's workstation.

6. Policy Updates & Security Disclosure

We may update this Privacy Policy periodically to reflect enhancements in web browser security standards. Changes take effect immediately upon publication. We encourage users to review this page periodically.

Frequently Asked Questions

Everything you need to know about our privacy guarantee.

Do my files ever get uploaded to a server?

No. 100% of file processing (PDF conversion, image compression, text formatting) runs inside your local browser via WebAssembly and JavaScript. Zero bytes are uploaded to remote servers.

Can I use Nextgen Astra tools offline?

Yes! Once you load any tool page in your web browser, you can disconnect your internet connection and all features will continue working seamlessly air-gapped.

Are health calculator entries stored?

No. Weight, height, age, and activity metrics entered into health tools are evaluated instantly in memory and discarded when you close or refresh the browser tab.

Is Nextgen Astra compliant for enterprise use?

Yes. Because zero data leaves the corporate browser sandbox, IT security teams allow Nextgen Astra for strict compliance environments including legal, medical, and financial operations.
