Privacy & limits
Updated 28 October 2026. Your answers, clues and lesson title are processed in this browser only. We do not upload or automatically save them. Reloading clears your work; use Save my input before leaving. Files you download stay on your device.
We record only fixed task-step counts grouped by day, input method, broad source and free/Plus tier. No lesson text, filenames, student information, visitor identifiers or analytics cookies are included. Do Not Track, Global Privacy Control, QA and billing return pages are excluded. Step counts keep the current and previous seven UTC date buckets. Separately, we use Cloudflare Web Analytics for aggregate page visits and performance, without analytics cookies or visitor identifiers. It does not read your answers, clues, lesson title or downloaded filenames. QA, Do Not Track, Global Privacy Control, preview hosts and pages whose current URL, original navigation or referrer has payment or recovery parameters do not load its third-party beacon. Page visits are separate from task completion, saved downloads, successful printing and purchases. Ordinary hosting request information is handled by Cloudflare.
Payment uses Creem and an independent product billing database for payment references and hashed access credentials. Creem handles payment and tax information; we do not receive card details. Necessary access cookies support purchase status and recovery; they are separate from analytics. We do not sell lesson information.
Do not paste student information or confidential material. The first version supports printable English ASCII, not pictures or other writing systems. Review every teaching definition and PDF before use. Physical printing has not been tested.
