1. Acceptance of Terms

By registering for, accessing, or using the QRYPTA Quantum-Safe Contract Integrity System ("Service") provided by Faihoplo Inc. ("Company," "we," "us," or "our"), you ("User," "Client," or "you") agree to be bound by these Terms and Conditions ("Terms"). If you do not agree to these Terms, you may not use the Service.

These Terms constitute a legally binding agreement between you and Faihoplo Inc. We reserve the right to modify these Terms at any time. Continued use of the Service after changes constitutes acceptance of the revised Terms.

2. Description of Services

QRYPTA is a post-quantum cryptography (PQC) based digital contract integrity system that provides:

• Quantum-safe digital signing using ML-DSA-65 (FIPS 204) and EC-DSA algorithms
• Quantum-safe key encapsulation using ML-KEM-768 (FIPS 203)
• AES-256-CBC encryption for contract security
• Multi-party contract signing with independent verification
• Permanent vault storage in AWS S3 with Object Lock (WORM)
• Complete legal audit trail with per-party IP, device, and timestamp recording
• SHA-256 contract integrity verification

3. Account Registration

3.1 Registration Requirements

To use QRYPTA services, you must register an account by providing:

• Full name (first and last name)
• Valid email address (used for identity verification)
• Phone number
• Date of birth (YYYY-MM-DD format) — used exclusively for client key recovery
• Country and address information
• Secure password (minimum 8 characters)

3.2 Account Security

You are responsible for maintaining the confidentiality of your account credentials. You agree to notify Faihoplo Inc. immediately of any unauthorized use of your account. Faihoplo Inc. is not liable for any loss resulting from unauthorized account access due to your failure to secure your credentials.

3.3 Email Verification

All accounts require email verification via One-Time Password (OTP). Unverified accounts cannot access paid services or store contracts in real AWS S3 vaults.

4. Client Key & Subscription Plans

4.1 Client Key

Upon purchasing a subscription plan, a unique Client Key (format: QRYP-XX-XXXXXXXX-XXXXXXXX) is generated and emailed to the registered email address. The Client Key:

• Is a private security key — keep it safe and confidential
• Is emailed to you immediately after payment
• Must be saved by the user
• Can be recovered using three-factor authentication (email + password + date of birth)
• Is required to store contracts in real AWS S3 vault storage

4.2 Subscription Plans

Subscription plans (Starter, Professional, Enterprise) are billed monthly. Each plan provides a Client Key valid for 30 days. Upon renewal, the same Client Key is extended — no new key is generated. Free tier accounts can use test storage without a Client Key.

4.3 Plan Limits

Each plan includes limits on monthly contracts, maximum parties, and maximum retention period. Exceeding plan limits requires an upgrade. Faihoplo Inc. reserves the right to modify plan pricing and features with 30 days advance notice.

5. Vault Storage & Object Lock

5.1 AWS S3 Object Lock

Contracts stored in real vault buckets are protected by AWS S3 Object Lock in Compliance Mode (WORM — Write Once Read Many). Once stored:

• Contracts cannot be modified or deleted by any party — including Faihoplo Inc. — until the retention period expires
• Retention periods range from 3 to 30 years depending on your selection
• Storage is governed by Amazon Web Services terms of service

5.2 Contract Integrity

Each contract is assigned a unique Contract ID and SHA-256 hash. These are embedded in the signed PDF and can be used to verify contract authenticity independently of Faihoplo servers.

5.3 User Responsibility

Users are responsible for selecting the appropriate retention period before storing. Object Lock prevents deletion — retention period selection is permanent and cannot be changed after storage.

6. Vault Continuation Policy

6.1 Monthly Payment Obligation

Vault storage protection is maintained through monthly subscription payments. By subscribing to a vault plan, you agree to pay the monthly subscription fee for the full selected retention period to maintain active vault access and management services.

6.2 Payment Interruption Procedure

If monthly payment is interrupted, the following procedure applies:

• Immediate notification: Faihoplo Inc. will send an email notification to your registered address within 24 hours of missed payment
• Grace period: A 6-month grace period begins from the date of first missed payment
• During grace period: Vault access is suspended (read-only) but documents remain protected in AWS S3 Object Lock
• Resolution options: Three options are available during the grace period (see Section 6.3)
• After grace period: If no resolution is made, vault access is permanently suspended (documents remain locked in AWS S3 until retention period expires)

6.3 Resolution Options Upon Payment Interruption

During the 6-month grace period, you may choose one of the following options:

• Option A — Resume Monthly Payments: Resume standard monthly subscription payments. All vault services are restored immediately upon payment.
• Option B — Pay Remaining Period Upfront: Pay the full remaining vault period as a lump sum. Vault services are restored and no further monthly payments are required for the original retention period.
  Formula: Remaining months × monthly vault fee = lump sum required
  Example (Enterprise 30yr, stopped at Year 10): 240 months × $35.99 = $8,637.60
• Option C — Archive Status: Accept vault archive status. Documents remain preserved and legally protected in AWS S3 Object Lock until retention period expires. Vault access (download, verify) is available upon payment of a one-time reactivation fee of $49.99. No new contracts can be stored.

6.4 Document Safety Guarantee

Regardless of payment status, all documents already stored in AWS S3 Object Lock are permanently protected:

• AWS S3 Object Lock (Compliance Mode) prevents deletion by any party — including Faihoplo Inc. — until the retention period expires
• Documents remain legally protected and tamper-proof throughout the full retention period
• QRYPTA quantum-safe signatures remain cryptographically valid for the full retention period
• Payment suspension does NOT affect the legal validity of stored contracts

6.5 Upfront Payment Option

Clients may choose to pre-pay the full vault period upfront at any time to eliminate monthly payment obligations:

• Starter (5yr): $17.72 × 60 months = $1,063.20 (one-time)
• Professional (10yr): $23.30 × 120 months = $2,796.00 (one-time)
• Enterprise (30yr): $35.99 × 360 months = $12,956.40 (one-time)

Upfront payment guarantees vault protection for the full retention period with no further payment obligations. A 5% discount applies to upfront payments as recognition of committed long-term partnership.

6.6 Price Review Policy

Vault management fees are reviewed every 5 years to account for actual inflation and operating cost changes. Existing subscribers are given 90 days advance notice before any price adjustment. Pre-paid vault clients are not subject to price reviews for their pre-paid period.

7. Payment & Billing

All payments are processed through PayPal. By purchasing a plan, you authorize Faihoplo Inc. to charge your PayPal account for the subscription amount. Payments are non-refundable once a Client Key has been generated and displayed. Faihoplo Inc. does not store payment card information.

8. Business Continuity Guarantee

Faihoplo Inc. has implemented two concrete strategies to ensure your contracts remain safe regardless of our business status:

Strategy 1: Pre-Paid AWS Storage Fee

Upon payment, Faihoplo Inc. pre-pays the full AWS S3 storage fee for your selected retention period directly to Amazon Web Services. This payment is made in advance and is independent of Faihoplo Inc.'s future financial operations. Your storage is guaranteed for the full retention period.

Strategy 2: Public Vault Manager Access

The QRYPTA Vault Manager is permanently hosted on public platforms including Faihoplo's API server and GitHub. Even if faihoplo.com becomes unavailable, clients can always access and download their contracts through these independent platforms using their Contract ID.

9. Intellectual Property

QRYPTA and all related technology, including patent-protected quantum-safe signing algorithms (HYTAK TRNG Patent 1, Key Zeroization Patent 2), are the exclusive intellectual property of Faihoplo Inc. Users may not copy, reverse engineer, or distribute any component of the QRYPTA system without written permission.

User-generated contracts and signed PDFs remain the intellectual property of the respective parties to the contract. Faihoplo Inc. does not claim any ownership over stored contracts.

10. Prohibited Uses

You agree not to use QRYPTA for:

• Fraudulent, illegal, or deceptive contracts
• Contracts involving illegal goods, services, or activities
• Harassment, abuse, or harm to other parties
• Circumventing security measures or attempting unauthorized access
• Storing malicious content or malware in vault storage
• Impersonating other persons or organizations
• Violating any applicable laws or regulations

Violation of prohibited uses may result in immediate account termination without refund.

The QRYPTA service is provided "as is" and "as available" without warranties of any kind. While Faihoplo Inc. uses enterprise-grade AWS infrastructure and NIST-standardized PQC algorithms, we do not warrant that the service will be uninterrupted, error-free, or that stored contracts will be accepted by all courts or jurisdictions without independent legal advice.

Users are advised to consult qualified legal counsel for contracts of significant legal or financial consequence.
