Niraiya | Privacy & Data Protection Policy

Q: How does Niraiya recover Excel passwords?

Niraiya uses multi AI-powered algorithms with cloud computing to decrypt Excel file passwords. Files are processed in your browser first, then cryptographic data is sent to servers for AI analysis, ensuring your actual file data never leaves your device.

Q: What makes Niraiya's AI approach different?

Unlike single-AI solutions, Niraiya leverages the combined intelligence of ChatGPT, Gemini, and DeepSeek. This means smarter pattern recognition, faster results, and higher success rates for unlocking Excel files — all while respecting each provider's usage policy.

Q: Is my Excel file secure with Niraiya?

Yes. Your complete Excel files remain on your device. Only encrypted metadata is processed on our servers. We use privacy-first browser processing with Blazor WASM to ensure file security and privacy compliance.

Q: What Excel file formats does Niraiya support?

Niraiya supports all Excel versions including .XLS, .XLSX, .XLM, and other Microsoft Office formats. Currently supporting Excel files with both sheet protection and workbook protection.

Q: How fast is the password recovery process?

Most Excel files are recovered within minutes using our AI cloud computing technology. Recovery time depends on password complexity and file encryption level.

Q: How much does Excel password recovery cost?

Niraiya offers pay-for-success pricing. You only pay when your file is successfully recovered. Pricing varies based on file complexity and encryption strength.

Our Commitment to Privacy

At Niraiya, we've built our Excel password recovery service around one core principle: your files and data should never leave your control. As someone who's spent years in cybersecurity and data protection, we understand the real risks of uploading sensitive files to third-party services. That's why we designed our system to process everything locally in your browser first.

This privacy policy explains exactly what happens to your data during the Excel password recovery process, backed by real-world examples and technical details. We don't just claim to be privacy-focused—we've architected our entire service around protecting your information.

What Data We Collect

When you use Niraiya to remove a password from an Excel file, we collect minimal information necessary to perform the recovery:

Password Hash: A mathematical fingerprint of your Excel file's password encryption. This hash contains no readable information about your actual file content, formulas, or data.
File Metadata: Basic information like file size, Excel version, and encryption type—nothing about your spreadsheet's contents.
Technical Logs: Anonymous performance data to improve our AI algorithms (no personal identifiers).

Example: If you have a financial spreadsheet with sensitive client data, we never see that data. We only work with the encrypted password information—think of it as analyzing the lock mechanism without ever opening the safe.

How We Process Your Data

Our privacy-first approach uses browser-based processing powered by WebAssembly technology. Here's the step-by-step breakdown:

Step 1: Local Processing

Your Excel file is analyzed entirely in your browser. We extract only the cryptographic hash of the password—essentially a digital fingerprint that tells us nothing about your file's contents.

Step 2: Secure Transmission

The hash is sent to our servers over 256-bit SSL encryption. Our AI systems analyze password patterns and attempt recovery using advanced algorithms.

Step 3: Digital AI Cloud Analysis

Machine learning algorithms work on the hash to identify likely password patterns. This happens in isolated, secure environments with no access to your original file.

Step 4: Auto-Delete

Once recovery is complete (or attempted), all data is automatically deleted within 24 hours. No permanent storage, no backups, no logs of your files.

Data Security Measures

Security isn't just a checkbox for us—it's how we prevent data breaches before they happen. Drawing from enterprise security practices, we've implemented multiple layers of protection:

End-to-End Encryption: All data transmission uses TLS 1.3 with 256-bit encryption keys.
Zero-Knowledge Architecture: Our servers never see your actual Excel file content.
Automated Data Deletion: All temporary data is wiped within hours using secure deletion protocols.
Regular Security Audits: Independent third-party audits ensure our systems remain secure.
Minimal Data Retention: We store nothing beyond what's needed for active recovery sessions.

Real-World Impact: Unlike traditional password recovery services that require full file uploads, our approach means even if our servers were compromised, attackers would find nothing useful—just mathematical hashes with no connection to your actual data.

Your Rights and Controls

You maintain complete control over your data throughout the process. Since processing happens locally first, you can stop at any time without any data being transmitted.

What You Control:

File access and processing initiation
Data transmission decisions
Recovery attempt cancellation
Complete local processing visibility

Your Rights:

Right to know what data we process
Right to stop processing at any time
Right to data deletion confirmation
Right to contact us about privacy concerns

International Data Transfers

Our servers are located in secure data centers within the USA and European Union, compliant with GDPR requirements. For users outside the EU, we ensure all data transfers meet local privacy regulations through standard contractual clauses and adequate protection measures.

Since most processing happens in your browser, international transfers are minimal and only involve the password hash data necessary for AI analysis.

Cookies and Tracking

We use minimal cookies for essential functionality:

Session Cookies: Temporary cookies to maintain your browser session during file processing.
Analytics: Anonymous usage statistics to improve our service (no personal data).
Security: Cookies to prevent abuse and ensure secure connections.

You can disable cookies in your browser settings, though this may limit some functionality.

Legal Basis and Compliance

Our data processing is based on:

Contract Performance: Processing necessary to provide the Excel password recovery service you requested.
Legitimate Interest: Improving our AI algorithms through anonymous performance data.
Legal Compliance: Adherence to GDPR, CCPA, and other privacy regulations.

We conduct regular privacy impact assessments and maintain detailed records of our processing activities.

Privacy FAQ

Yes, most traditional services require you to upload your complete Excel file to their servers. This means your sensitive data—financial records, client information, personal data—is stored on their systems, potentially accessible to employees or vulnerable to breaches. Our browser-first approach ensures your actual file content never leaves your device.

If you stop the process before the hash is sent to our servers, nothing has been transmitted. If the hash has already been sent for AI processing, it will be automatically discarded from our systems. You maintain full control throughout.

Our AI systems work exclusively with password hashes and pattern recognition algorithms. The machine learning models improve by analyzing successful password recovery patterns, not by memorizing specific file contents or user data. Each recovery session is isolated and doesn't influence future processing of other files.

Our privacy-first architecture was specifically designed for these scenarios. Since processing happens locally in your browser first, you can verify that only the password hash (not your sensitive content) is being transmitted. This approach is compliant with HIPAA, GDPR, and other regulations requiring data minimization. Many law firms and healthcare organizations use Niraiya for this reason.
