我们保存什么
当你使用 Google 或 Microsoft 登录时，我们保存登录服务提供的邮箱地址、显示名称和不可复用的账户标识。nice.day 不保存你的登录密码。
未登录时写下的普通文字默认保存 7 天。登录后写下或由你主动认领的文字会长期保存在你的账户中，直到你自行删除。选择“让陌生人听见”的文字即使被长期保存，也只会在公开池中展示 7 天。
当你写“给未来的信”时，我们保存信件主题、正文、计划发送时间、投递状态以及收件邮箱。信件发出或最终失败后，相关记录最多再保留 30 天。
我们怎样使用这些信息
登录信息只用于识别你的账户、展示你自己的文字和信件，并把信寄回该账户邮箱。私密文字和未来信不会公开，所有内容都不会用于广告。
环境声音默认关闭，只有在你主动点击后才从 nice.day 自己的服务器加载。声音选择只使用当前页面已有的时间与天气信息。

Privacy notice
Updated July 24, 2026
When you sign in with Google or Microsoft, we store the email address, display name, and provider account identifier returned by that service. nice.day never stores your provider password.
Ordinary words written while signed out are kept for 7 days. Words written while signed in, or explicitly claimed after sign-in, remain in your account until you delete them. A retained public message stays in the public listening pool for only 7 days.
A future letter includes its subject, body, scheduled delivery time, delivery status, and destination email. Sent or permanently failed records are retained for no more than 30 additional days.
This information is used only to identify your account, show your own words and letters, and deliver letters to your sign-in email. Private words and future letters are not public, and content is not used for advertising.
Ambient sound is off by default and loads from nice.day only after you turn it on. The selection uses only the time and weather context already present on the page.
Cloudflare provides hosting, storage, and scheduling; Google or Microsoft provides authentication; Resend delivers mail from have@nice.day.
You can view and delete retained words under “My words.” To request account deletion or help with a pending letter, email have@nice.day.
