How buying works

A one-time purchase delivers the binary or pack, an Ed25519-signed license key, and a year of updates. The tool verifies its own signature at load — no phone-home licensing, no telemetry. Checkout and tax are handled by Polar as merchant of record; your download link and key arrive by email the moment payment clears.
