隱私政策

更新日期:2026 年 10 月 11 日

我們只為登入、提問、保存記錄、付款,以及你主動開啟的「書的記憶」與「回訪」而處理你的資料。下面說明保存什麼、交給誰、保存多久,以及你能怎麼做。

我們保存什麼

手寫、錄音與文字怎麼處理

服務提供方與資料去向

本站運行在 Cloudflare 上(網站託管、資料庫與語音轉文字)。回答由階躍星辰(StepFun)的語言模型生成:你的問題文字、手寫時的筆跡圖片,以及在你開啟記憶時書的記憶筆記,會在生成回答時傳給它。在你開啟記憶時,書每回答一次,還會把你的問題、書的回答(只取前段)與已有的筆記再交給同一個模型一次,讓它整理新的筆記。驗證碼郵件由 Resend 寄出,付款由 Stripe 完成,人機驗證由 Cloudflare Turnstile 完成。Google 登入與手機簡訊登入目前未啟用。這些服務會在完成各自功能所必需的範圍內接收資料,並可能在你所在地之外處理;它們各自如何保存資料,以其條款與政策為準。如果你開啟通知,提醒會經由你瀏覽器廠商的推送服務(Google、Apple、Mozilla 或 Microsoft)送達:訊息經過加密、不含內容,但該服務知道你的瀏覽器在什麼時間收到了一則訊息。

日誌

網站的執行環境會記錄請求的時間、路徑與結果碼等中繼資料。我們不把你的問題、書的回答、記憶或錄音寫進日誌。

保存與刪除

驗證碼短期失效,會話可登出撤銷。你可以刪除單條或全部問答;刪除問答不會刪除書的記憶,記憶在「書的記憶」頁另外管理,可逐條刪除、匯出或全部清空。你可以注銷帳號:身分、會話、問答、記憶、回訪與推送訂閱都會被刪除;支付記錄因財務與反詐騙稽核而去識別後保留,並按適用法律的要求保存。Cloudflare 的資料庫有還原功能,過往的狀態可能在其保留期內仍然存在。

你的選擇

你可以不建立帳號,只體驗書寫;提交問題需要登入。記憶、回訪與推送預設關閉,你可以隨時開啟或關閉。你也可以關閉音樂、刪除問答、登出或注銷帳號。如需查詢、更正或行使其他法定權利,請來信:(聯絡信箱待補)。

年齡

本服務供年滿 18 歲的人使用。開啟記憶與回訪時,會再請你自己確認已年滿 18 歲,並記下你確認的時間。

政策的變更

政策有變更時,我們會更新上方的日期。

請勿在問題中提交身分證號、銀行卡號、醫療病歷等不必要的敏感資料。

我们保存什么

手写、录音与文字怎么处理

服务提供方与数据去向

本站运行在 Cloudflare 上(网站托管、数据库与语音转文字)。回答由阶跃星辰(StepFun)的语言模型生成:你的问题文字、手写时的笔迹图片,以及在你开启记忆时书的记忆笔记,会在生成回答时传给它。在你开启记忆时,书每回答一次,还会把你的问题、书的回答(只取前段)与已有的笔记再交给同一个模型一次,让它整理新的笔记。验证码邮件由 Resend 寄出,付款由 Stripe 完成,人机验证由 Cloudflare Turnstile 完成。Google 登录与手机短信登录目前未启用。这些服务会在完成各自功能所必需的范围内接收数据,并可能在你所在地之外处理;它们各自如何保存数据,以其条款与政策为准。如果你开启通知,提醒会经由你浏览器厂商的推送服务(Google、Apple、Mozilla 或 Microsoft)送达:讯息经过加密、不含内容,但该服务知道你的浏览器在什么时间收到了一则讯息。

日志

网站的执行环境会记录请求的时间、路径与结果码等元数据。我们不把你的问题、书的回答、记忆或录音写进日志。

保存与删除

验证码短期失效,会话可退出撤销。你可以删除单条或全部问答;删除问答不会删除书的记忆,记忆在「书的记忆」页另外管理,可逐条删除、导出或全部清空。你可以注销账号:身份、会话、问答、记忆、回访与推送订阅都会被删除;支付记录因财务与反欺诈审计而去标识后保留,并按适用法律的要求保存。Cloudflare 的数据库有还原功能,过往的状态可能在其保留期内仍然存在。

你的选择

你可以不建立账号,只体验书写;提交问题需要登录。记忆、回访与推送默认关闭,你可以随时开启或关闭。你也可以关闭音乐、删除问答、退出或注销账号。如需查询、更正或行使其他法定权利,请来信:(联系邮箱待补)。

Privacy Policy

Updated 11 October 2026

We handle your data only to sign you in, answer your questions, keep your records, take payment, and run “the book’s memory” and “revisits” if you switch them on. Below is what we keep, who gets it, for how long, and what you can do.

What we keep

How handwriting, recordings and text are handled

Service providers and where data goes

This site runs on Cloudflare (hosting, the database and speech-to-text). Answers are generated by a StepFun language model: your question text, the picture of your handwriting when you write by hand, and the book’s memory notes when you have switched memory on are sent to it when an answer is generated. When memory is on, after each answer the book also sends your question, the start of the answer and your existing notes to the same model once more, to write new notes. Verification emails are sent by Resend, payments are taken by Stripe, and bot checks are run by Cloudflare Turnstile. Sign-in with Google and by mobile text message is not currently enabled. These providers receive data only as far as their function needs, and may process it outside where you live; how each keeps data is governed by its own terms and policies. If you switch on notifications, the reminder is delivered through the push service of your browser’s maker (Google, Apple, Mozilla or Microsoft): the message is encrypted and carries no content, but that service knows your browser received a message and when.

Logs

The site’s runtime records request metadata such as time, path and result code. We do not write your questions, the book’s answers, memory or recordings into logs.

Keeping and deleting

Codes expire quickly and sessions can be ended by signing out. You can delete single or all question records; deleting question records does not delete the book’s memory, which is managed separately on the “book’s memory” page, where you can delete items one by one, export them, or clear them all. You can delete your account: your identity, sessions, question records, memory, revisits and push subscription are removed; payment records are kept in de-identified form for financial and anti-fraud audit and as applicable law requires. Cloudflare’s database has a restore feature, so earlier states may still exist within its retention period.

Your choices

You can use the writing page without an account; asking a question needs you to sign in. Memory, revisits and push are off by default and you can switch them on or off at any time. You can also turn off the music, delete question records, sign out or delete your account. To ask about, correct, or exercise other legal rights over your data, write to: (contact email to be added).

Age

The service is for people aged 18 or over. When you switch on memory and revisits you are asked to confirm, yourself, that you are 18 or over, and the time you confirmed is recorded.

Changes to this policy

If this policy changes we will update the date above.

Please do not put ID numbers, bank card numbers, medical records or other unnecessary sensitive details into your questions.
