生效日期:2026 年 6 月 1 日
Deckvi(以下简称“我们”,由独立开发者运营)是一个 HTML 演示稿的播放、组织、分享与发现平台。我们重视你的隐私,本政策说明我们收集哪些信息、如何使用与保护,以及你拥有的权利。使用 Deckvi 即表示你已阅读并理解本政策。
1. 我们收集哪些信息
(a) 你主动提供的信息
- 账号信息:邮箱地址;以及你的密码——密码由认证服务以单向哈希方式处理(不可逆),我们无法看到明文。
- 个人资料:用户名、显示名、个人简介、头像图片(如你上传)。
- 你创建的内容:你上传并选择分享的演示稿 HTML 文件及其标题、缩略图。
(b) 你使用服务时自动产生的信息
- 互动数据:你的收藏、关注关系,以及你作品被浏览的次数。
- 实时演讲数据:当你或他人开启“演讲者/实时跟随”时,参与者的在线状态与当前页码会被临时同步,用于实时跟随,会话结束即不再保留。
- 偏好设置:语言、主题(深/浅色)等,存于你浏览器本地。
- 基本技术信息:如浏览器语言(用于自动匹配中英文)。我们目前不接入第三方广告或行为分析追踪。
(c) 本地存储的信息(不上传)
- 登录状态与上述偏好存储在你浏览器的 localStorage 中。
- 桌面客户端中,你导入的演示稿副本存储在你本机设备上,不会上传——只有你主动点击“分享”的演示稿才会上传到云端。
2. 我们如何使用这些信息
- 提供与维护服务:账号登录、播放与组织演示稿、分享与发现。
- 展示作者身份与作品:在作者主页、发现广场、分享页展示你的用户名、头像、简介与公开作品。
- 运营发现广场:根据浏览数、收藏数等对公开内容排序。
- 实现实时跟随演讲功能。
- 保障账号与平台安全、防范滥用。
3. 信息的存储与第三方处理者
我们不出售你的个人信息。为提供服务,我们使用以下第三方基础设施处理者,你的相关数据会存储于其服务器:
- Supabase:账号认证、数据库、实时同步。
- Cloudflare(R2 + Pages):演示稿 HTML 与图片的对象存储、网站托管与内容分发(CDN)。
- Google Fonts:加载页面字体(加载时 Google 可能获取你的 IP 地址)。
这些服务商按其自身隐私政策处理数据。除为提供服务所必需、经你同意、或法律要求外,我们不向其他第三方共享你的个人信息。
此外,用户上传的演示稿 HTML 可能包含创作者自行嵌入的第三方资源(脚本、字体、图片、分析代码等),这些资源由创作者控制、不在 Deckvi 的控制范围内。本政策所述“不接入第三方追踪”指 Deckvi 平台自身,并不代表你打开的每一个演示稿都不会加载任何第三方资源。
4. 公开内容提示
当你将演示稿设为公开 / 可分享时:任何获得分享链接的人都可以查看它;它可能出现在发现广场、你的作者主页;你的用户名、头像、简介将作为作者信息公开展示。请不要在打算公开分享的演示稿中放入你不希望公开的个人信息或敏感内容。
5. 跨境数据传输
我们使用的 Supabase、Cloudflare、Google 等服务商的服务器可能位于你所在国家/地区之外,你的数据可能在境外被存储和处理。我们会在适用法律要求的范围内采取必要的保护措施。若未来正式面向欧盟等地区用户,我们将补充相应的跨境传输机制,以及你作为数据主体的权利与投诉渠道说明。

Privacy Policy
Effective date: June 1, 2026
Deckvi ("we", operated by an independent developer) is a platform for playing, organizing, sharing, and discovering HTML presentations. We respect your privacy. This policy explains what we collect, how we use and protect it, and your rights. By using Deckvi, you confirm you have read and understood this policy.
1. Information We Collect
(a) Information you provide
- Account: your email address; and your password, which our authentication provider stores using one-way hashing (irreversible) — we cannot see the plaintext.
- Profile: username, display name, bio, and avatar image (if uploaded).
- Content you create: presentation HTML files you upload and choose to share, plus their titles and thumbnails.
(b) Information generated as you use the service
- Interaction data: your bookmarks, follows, and the view counts of your works.
- Live presenting data: when a "presenter / live follow" session is active, participants' presence and current slide are temporarily synced to enable following, and are not retained after the session ends.
- Preferences: language and theme (dark/light), stored locally in your browser.
- Basic technical info: e.g. browser language (to auto-select Chinese/English). We currently do not use third-party advertising or behavioral analytics tracking.
(c) Locally stored information (not uploaded)
- Login state and the preferences above are stored in your browser's localStorage.
- In the desktop app, copies of presentations you import are stored on your own device and are not uploaded — only presentations you actively choose to "share" are uploaded to the cloud.
2. How We Use This Information
- To provide and maintain the service: login, playing and organizing presentations, sharing and discovery.
- To show creator identity and works: displaying your username, avatar, bio, and public works on author pages, the discovery feed, and share pages.
- To run the discovery feed: ranking public content by view count, bookmark count, etc.
- To enable the live-follow presenting feature.
- To protect account and platform security and prevent abuse.
3. Storage and Third-Party Processors
We do not sell your personal information. To operate the service we use the following third-party infrastructure processors, on whose servers your data is stored:
- Supabase: authentication, database, realtime sync.
- Cloudflare (R2 + Pages): object storage for presentation HTML and images, website hosting, and content delivery (CDN).
- Google Fonts: loading page fonts (Google may receive your IP address when fonts load).
These providers process data under their own privacy policies. We do not share your personal information with other third parties except as necessary to provide the service, with your consent, or as required by law.
In addition, presentation HTML uploaded by users may contain third-party resources embedded by the creator (scripts, fonts, images, analytics code, etc.); these are controlled by the creator and are outside Deckvi's control. Our statement that we do not use third-party tracking refers to the Deckvi platform itself, and does not mean that every presentation you open is free of third-party resources.
4. Public Content Notice
When you make a presentation public / shareable: anyone with the share link can view it; it may appear in the discovery feed and on your author page; your username, avatar, and bio are displayed publicly as creator information. Please do not include personal or sensitive information you wish to keep private in presentations you intend to share publicly.
5. Cross-Border Data Transfer
The servers of the providers we use (Supabase, Cloudflare, Google, etc.) may be located outside your country/region, and your data may be stored and processed abroad. We will take necessary safeguards to the extent required by applicable law. If we later serve users in regions such as the EU, we will add the corresponding cross-border transfer mechanisms and an explanation of your rights and complaint channels as a data subject.
6. Your Rights
- Access / correct: edit your display name, bio, avatar, and password in the app's Settings.
- Delete: contact us at the email below to request deletion of your account and related content.
- Withdraw consent / close account: you may stop using the service and request account closure at any time.
We will respond to your request within a reasonable time, except where the law provides otherwise.
7. Minors
Deckvi is not directed to children under 14 and does not allow users under 14 to register for or use account services. If we learn that an account was registered or used by a child under 14, we will delete that account and the related personal information.
8. Cookies and Local Storage
We use only necessary local storage (localStorage) to keep your login state and preferences. We do not use third-party advertising or cross-site tracking cookies.
9. Data Retention
We retain your information while your account is active. After you delete your account, we will erase your personal information and content within a reasonable period, unless retention is required by law.
10. Changes to This Policy
We may update this policy from time to time. We will prominently notify material changes on the website. Continued use after changes means you accept the updated policy.
