- When you sign in with a Google, Apple, Yahoo! JAPAN or LINE account, or subscribe to and manage a paid plan (Stripe, Inc.), you are taken to that company’s pages and information is sent to it, as governed by its privacy policy. The Taiyaku website does not load these companies’ scripts.
- The website’s fonts are served from our own servers; no external font service is used.
- “Listen” on a selection uses your browser’s speech synthesis. Depending on the browser and voice, the text read aloud may be sent to the browser vendor’s servers.
- Information that our servers send to AI providers and other processors (for example, to translate) is described in “Provision to Third Parties and Outsourcing” of the Privacy Policy.
We will revise this page when we add or change recipients or the information sent.
