Kehai is web analytics for people who run websites and online stores and need numbers they can defend. The tracker sets no cookie and writes nothing to browser storage; visitor and visit codes are salted hashes scoped to one site and one UTC day. Nothing is sampled, thresholded, or modeled into a measured figure, and every count carries the rule that produced it, including a bot ledger and AI assistant traffic counted apart. History from GA4, Plausible, or Umami imports with its source labeled, forecasts and pacing targets stay separate from measured data, and ecommerce revenue arrives from the server, with refunds and currencies handled, through Stripe, WooCommerce, PrestaShop, Wix, or Squarespace. Every dataset is available over REST and an MCP server, and the whole site exports as one file. Kehai runs on hardware managed in Warsaw under EU law, publishes its data processing agreement and subprocessors, and is funded by subscriptions rather than by anything it learns about visitors.
