Local-First Security Architecture

ZERO REMOTE TRACKING Zero-Cost Operating Model Client-Side IndexedDB

1. Security Philosophy: Data Sovereignty

Competitive ad research is one of the most sensitive operational activities inside high-scale e-commerce brands, SaaS companies, and growth agencies. Knowing which competitor angles your team is tracking can reveal upcoming product launches, positioning pivots, and acquisition funnels.

The Local-First Rule

The safest database is the one that never exists on an external server. SwipeRip operates on your local machine. No external SaaS company can leak your research because your research never leaves your browser.

2. Enterprise Threat Model & Mitigation

Vulnerability Vector Traditional Cloud Swipe Tools SwipeRip Local-First Architecture
Central Database Breach High risk: thousands of accounts exposed Zero risk: zero central databases exist
Competitor Angle Leakage Cloud telemetry exposes watched brands Zero risk: queries execute locally
Service Outages Research stalls when servers go down 100% uptime: runs completely offline
Mandatory Subscriptions Recurring API server bills $0 operating cost: on-device compute

3. IndexedDB Vault Engine

SwipeRip uses a high-performance local database layer built on Dexie.js / HTML5 IndexedDB.

  • Browser-Level Isolation: Data stored in IndexedDB is isolated to the SwipeRip extension origin ID. External web pages and scripts cannot read your saved cards.
  • Zero Storage Quota Caps: With the unlimitedStorage permission, your local library can scale to thousands of video clips and transcripts without silent truncation.
  • Instant Export: You can create single-click local backups as JSON or standard ZIP files to share directly with your video editors.

4. Offline-First Computation ($0 Operating Cost)

Hook deconstruction and UGC script remixing operate through the Direct-Response Copywriting Matrix:

  • Deterministic Rule Engine: Pattern matching algorithms classify hooks into 7 proven archetypes without querying external cloud models.
  • Chrome Built-in AI (window.ai): On supported Chromium builds with Gemini Nano, inference executes directly on your device GPU/NPU.
  • Zero Network Overhead: Creative briefs generate with 0ms latency, even on airplanes or in disconnected environments.

5. BYO Key Handling & Encryption

If you optionally configure a Bring-Your-Own (BYO) Google AI Studio key:

  • The key is saved locally in Chrome encrypted storage (chrome.storage.local).
  • Outbound requests travel over TLS 1.3 directly to Google's official Gemini endpoint (generativelanguage.googleapis.com).
  • No intermediary server ever sees, proxies, or logs your private API key.

6. Manifest V3 Sandboxing & Isolation

SwipeRip is built strictly on Chrome Manifest V3 standards:

  • Zero Remote Code Execution: All scripts are packaged locally inside the signed extension bundle. Dynamic eval() and remote script injections are blocked by default.
  • Minimal Permissions Scope: The extension cannot read browser cookies, autofill fields, passwords, or navigation on unapproved websites.
  • Content Script Isolation: Scrapers run inside isolated JavaScript worlds, preventing third-party ad library scripts from tampering with your saved ads.
