Security First
Your documents contain sensitive information. SeekerPDF is built from the ground up with security and privacy as core principles, not afterthoughts.
Your documents never touch our servers
All processing happens on-device. AI requests go directly to your LLM provider.
Security Features
Multiple layers of protection for your sensitive documents.
7-Layer AI Guardrails
Every LLM call passes through input validation, rate limiting, injection detection (17 patterns), PII redaction (12 types), content policy, output validation, and quality checks.
PII Auto-Redaction
Automatically detects and redacts emails, SSN, credit cards (Luhn-validated), phone numbers, IP addresses, passports, and 6 more PII types before data reaches the LLM.
Keychain Encryption
API keys stored in the iOS Keychain with hardware-backed encryption. HMAC-SHA256 request signing and API key rotation support.
Biometric Authentication
Face ID / Touch ID app lock with configurable auto-lock timeout. Failed attempt lockout after 5 tries.
Prompt Injection Detection
17 weighted regex patterns detect instruction overrides, DAN jailbreaks, system prompt extraction, role hijacking, and chat template injection attacks.
On-Device / Local AI
Ollama integration for fully local AI processing. Documents never leave your device. Zero-knowledge architecture for all providers.
Certificate Pinning
SSL certificate pinning for all API calls. TLS 1.3 encryption in transit. Request signing with HMAC-SHA256.
Runtime Protection
Jailbreak detection, debugger attachment detection, app tamper detection, screenshot protection, and app switcher preview hiding.
Observability & Audit
Real-time guardrails dashboard: injection scores, toxicity trends, PII redaction counts, violation breakdown, and JSON-exportable audit trail.

Security Best Practices
- All data in transit encrypted with TLS 1.3 with certificate pinning
- 7-layer AI guardrails middleware intercepts every LLM API call
- PII auto-redacted from prompts before reaching any LLM provider
- AI output scanned for PII leaks, system prompt leaks, and hallucination risk
- Prompt injection detection with 17 weighted patterns and confidence scoring
- Full audit trail with JSON export: timestamps, verdicts, scores, violations
- Rate limiting (30/min, 500/hour) prevents abuse and cost overruns
- On-device AI via Ollama — documents never leave your device
- No analytics or tracking in documents; privacy manifest included
