Terms
Effective 24 October 2026
The library
PinyinNotes on the web lets you read approved Mandarin notes and copy them into the PinyinNotes app. Richsen Steven provides the website and the app. Using either one means you agree to these terms.
Accounts
An account is created after an admin accepts your request. You choose your own password. You are responsible for the activity on your login. An admin may reject a note, unpublish it, or remove an account that misuses the site.
Notes you submit
You keep ownership of the notes you write. By submitting a note you confirm you have the right to share it, and you let us display the approved text so other people can copy it into the app for personal study. Do not submit someone else's course materials, or anything unlawful.
Accuracy
Pinyin on this website is a preview. The app generates Pinyin on the device, and a character with several readings may be wrong. The notes are a study aid, not a dictionary or a teacher. Premium features in the app are sold by Apple or Google under their terms. This website does not process those payments.
Liability and law
The website and the app are provided as they are. To the extent the law allows, Richsen Steven is not liable for lost study data or for a note that is incomplete or inaccurate. These terms are governed by the laws of Indonesia.
