Privacy policy

What this reading experience collects - And what it does not ask for.

A calculation stays inside a browser frame while a request envelope sits outside.

Reading without an account

The application does not set analytics cookies, include third-party tracking scripts, or require registration. It never asks for a private key or recovery phrase. Fonts, scripts, and images are served locally.

Requests and tools

Your web requests necessarily include technical information such as an IP address and user agent. Hosting or proxy infrastructure may record that information. The included server configuration logs errors and does not enable access logging; production infrastructure settings need a separate review.

Search terms appear in the URL and are sent to this server to find matching articles. Avoid entering personal or secret information. Calculator inputs and checklist answers remain in browser memory and are not submitted. External links take you to sites with their own privacy practices.

Market data

The price updater requests public market data from Coinbase on the server. It does not send visitor addresses or wallet information. No newsletter, advertising profile, or visitor database is implemented.

What a calculator visit shares

Page requests and tool inputs are different

Opening the gas calculator requests a page from this server. Changing the gas and gwei fields runs the calculation in your browser. The fields are not sent to the server or saved for a later visit. Opening a source link makes a separate request to that source’s website.
