What is ParityEdge and what does it do?

ParityEdge is a sub-10ms edge Purchasing Power Parity (PPP) localization platform and developer SDK. It converts global SaaS pricing into regional discounts across 190+ countries, injects coupons into Stripe and Lemon Squeezy checkouts, and renders isolated Shadow DOM banners with near-zero layout shift (<0.01 CLS).

How do I install the parityedge npm package?

You can install the official parityedge package via npm by running `npm install parityedge` (or `pnpm add parityedge`, `yarn add parityedge`). It has zero third-party runtime dependencies and is under 3 kB gzipped.

How does ParityEdge prevent VPN abuse on discounted pricing?

ParityEdge inspects incoming Autonomous System Numbers (ASNs) at the edge against a comprehensive threat database of 500+ commercial datacenter and proxy providers (such as AWS, Google Cloud, DigitalOcean, Hetzner). Datacenter and VPN visitors are automatically served standard base pricing to stop geographic arbitrage.

How do I use ParityEdge with React and Next.js 15?

After installing `parityedge`, import the React hook and banner component: `import { useParityEdge, ParityBanner } from "parityedge/react";`. It provides zero-flicker SSR hydration and automatic price mutation.

Architecturally Guaranteed Zero Personally Identifiable Information (PII)

ParityEdge is intentionally engineered so that you never have to worry about end-user data collection, cookie tracking consents, or cross-border PII transfer liabilities. We do not log, persist, track, or monetize visitor IP addresses, browser fingerprints, or personal identities. Geolocation classification happens entirely in ephemeral edge node memory and is discarded within milliseconds.

Ephemeral Edge Resolution (No IP Logging)

When an end-user navigates to a web storefront or application integrating ParityEdge, our edge nodes receive standard TCP/IP packet headers:

In-Memory Evaluation: The incoming IP address is evaluated strictly inside a stateless ParityEdge edge node for the solitary purpose of identifying the two-letter ISO country code (e.g. IN, BR) and Autonomous System Number (ASN) to detect commercial VPN datacenters.
Zero Disk or Database Persistence: The IP address is immediately dropped from RAM upon completing the discount calculation (<10ms). It is never written to disk, database tables, or server logs.
No Behavioral Profiling: We do not track user browsing paths, mouse movements, device identifiers, or purchase histories. Parity discounts are coarse macroeconomic adjustments, not individual behavioral tracking.

Client-Side Browser Storage & ePrivacy Cookie Exemption

The ParityEdge client script (parityedge) respects user privacy by operating completely cookie-free:

Strictly Necessary Functional Storage: We use browser sessionStorage (5-minute TTL) solely to prevent redundant network lookups as visitors navigate between pages on the same website.
Banner Dismissal: A simple boolean flag is saved in localStorage when a visitor closes a discount pill, ensuring they are not bothered again during that session.
No Cookie Consent Banner Required: Under Article 5(3) of the European ePrivacy Directive and national implementing legislation, strictly necessary functional storage does not require user consent or cookie banners. We do not set third-party tracking cookies or advertising beacons.

Customer & Account Information

For registered customers and software founders who create an administrative ParityEdge account, we store only the minimal operational data required to deliver our service:

Account Credentials: Work email address, encrypted authentication identifiers, and project API keys.
Project Configuration: Whitelisted domain names, tier discount percentages, custom seasonal holiday campaign overrides, and UI banner styling preferences.
Aggregated Counters: Monthly lookup tallies per project ID to track quota allowances and prevent abuse.
PCI-DSS Compliant Payment Data: All payments and subscription billing are processed by our PCI-DSS certified Merchant of Record partners. ParityEdge does not store or process payment card numbers.

Global Data Protection Compliance (GDPR, CCPA/CPRA, DPDP, LGPD)

ParityEdge adheres to international privacy regulations across all major jurisdictions:

European Union & UK GDPR:

Our ephemeral Zero-PII data plane guarantees that no personal data of European storefront visitors is processed, stored, or transferred to third-party data brokers. Registered account holders maintain full rights of data access, correction, and erasure.

California Consumer Privacy Act (CCPA / CPRA):

ParityEdge does not sell or share consumer personal information under California law. We have zero data monetization streams outside of direct software subscriptions.

India Digital Personal Data Protection Act (DPDP Act 2023):

All edge evaluations within India process geolocation without storing personal data fiduciaries or biometric records, maintaining full compliance with statutory data fiduciary requirements.

Brazil LGPD (Lei Geral de Proteção de Dados):

Brazilian visitors receive localized pricing through our São Paulo edge nodes with full respect for data minimization and privacy-by-design standards.
