Your Deal. Your Data. Your Vault.
We use bank-grade encryption to ensure your negotiation strategy remains 100% private from dealerships and data brokers.
1. Our Security Philosophy
At SignSpark AI, we know that a car contract contains your most sensitive personal information—from your home address to your credit tier. We built our platform with a "Privacy First" architecture, ensuring that your data is seen only by you and our AI, never by the dealership you are negotiating with.
2. How We Protect Your Data
🛡️ Bank-Grade Encryption
- In Transit: All data sent between your device (mobile or desktop) and our servers is encrypted using TLS 1.3 (Transport Layer Security). This is the same standard used by major banks and financial institutions.
- At Rest: Once your documents reach our secure cloud, they are encrypted using AES-256 (Advanced Encryption Standard). Even if someone physically stole our servers, your data would remain unreadable.
💳 Payment Security (PCI-DSS)
- We Do Not Store Your Card: When you upgrade to SignSpark Pro, your payment is processed directly by our payments partner (Stripe/Paddle), a PCI Service Provider Level 1 certified processor.
- Zero-Knowledge Transactions: SignSpark AI never sees or stores your full credit card number or CVV code.
☁️ Secure Infrastructure
- Cloud Security: Our platform is hosted on industry-leading cloud providers (e.g., AWS/Google Cloud) that maintain ISO 27001 and SOC 2 Type II compliance.
- Data Isolation: Your account data is logically isolated. Our AI processes your contract in a "sandboxed" environment that prevents data leakage between users.
3. AI Safety & Ethics
- No "Data Training" on PII: We do not use your Personally Identifiable Information (Name, Address, VIN) to train our public AI models. Your personal contract details remain yours.
- The "Dealer Firewall": A common fear is that using an app will alert the dealer. SignSpark AI is completely independent. We do not share your "Fairness Score," "Hidden Fee" alerts, or negotiation limits with any dealership, lender, or manufacturer.
4. Access Controls
- Least Privilege Access: Our internal systems are designed so that SignSpark employees cannot access your uploaded documents unless you explicitly grant permission for a customer support issue.
- Audit Logging: We maintain strict logs of all system access to detect and prevent unauthorized activity.
