Privacy

This page describes what the demo site at demo.helius.dev collects, what it forwards to upstream services, and how to opt out of analytics.

Scope

This policy covers the demo application at demo.helius.dev, which is a read-only Solana RPC showcase built on the open-source helius-labs/frontend-boilerplate template. It does not cover helius.dev or the Helius dashboard, which have their own privacy policy.

What the demo collects

  • No accounts. The demo has no sign-up, login, or password — there is no user account to create or delete.
  • No personally identifying information. We do not request email, name, address, or payment details. Connecting a Solana wallet only exposes its public address.
  • Wallet public addresses. Addresses you type into demo inputs or connect via Phantom are forwarded to Helius RPC to fetch on-chain data. The site does not store them.
  • Aggregate analytics. We use Vercel Analytics and Vercel Speed Insights to measure page views, performance, and Core Web Vitals. These tools do not use cookies and do not identify individual visitors. See Vercel's privacy policy for details.

What is forwarded to Helius

All Solana RPC calls go through the server-side proxy at /api/rpc, which forwards the request to Helius mainnet RPC using a server-held API key. Helius receives:

  • The RPC method name and parameters you submitted
  • The originating IP address of the demo's server (not yours)
  • Standard HTTP headers (no cookies, no auth tokens)

See the Helius privacy policy for what Helius does with that traffic.

Third-party services

  • Helius — Solana RPC and DAS API
  • Vercel — hosting, analytics, speed insights
  • Phantom Connect — wallet integration; only invoked when you click "Connect Wallet"

Cookies

The demo uses one local-storage entry to remember your color theme preference (light/dark/system). It does not set tracking cookies.

AI crawler policy

The demo welcomes AI crawlers and agent traffic. Robots policy is at /robots.txt, and machine-readable metadata is at /llms-full.txt and /.well-known/agent-card.json.

Data retention

The demo does not persist any user data. Server logs are retained per Vercel's default policy (typically 30 days).

Children

The demo is intended for software developers. It is not directed at users under 13.

Changes

We update this page when the demo changes. The Last updated date above reflects the most recent revision.
