用户协议
版本 1.0 · 最后更新 2026-10-25 · 生效日期 2026-10-25
1. 接受本协议
本用户协议（下称「本协议」）是你与 Lu Li（下称「我们」或「开发者」）之间就使用 Lumen Notes 移动应用及其更新、功能与内容（下称「本 App」）达成的法律协议。
下载、安装或使用本 App，即表示你同意本协议及我们的隐私政策。若不同意，请勿使用并删除本 App。
2. 使用资格
你须年满 13 周岁（EEA / 英国为 16 周岁）。未成年人须在父母或监护人参与下使用本 App。
3. 本 App 能做什么、不能做什么
Lumen Notes 是一个本机 Markdown 笔记本：
- 用 Markdown 书写，并在编辑与预览之间切换；
- 用
#标签（支持 #work/meeting 层级）组织笔记，置顶或归档；
- 搜索全部笔记，并按标签筛选；
- 添加图片与文件附件，重复图片只存一份；
- 自动保存草稿，中断后可恢复；
- 把整个笔记库导出为 ZIP 备份，并在其他设备导入。
你必须了解的限制：
| 事项 |
你需要知道 |
| 本 App 不是备份服务 |
笔记只保存在本机。删除 App 会删除笔记与附件，除非你已导出备份或另有设备备份。请定期导出备份并存放在本机以外。 |
| 备份未加密 |
导出的 ZIP 是明文，任何拿到该文件的人都能读取你的笔记。请妥善保管，并通过可信渠道传输。 |
| 没有同步 |
本版本没有 iCloud 同步、多设备同步、小组件、分享扩展或 Siri 集成。换设备需手动导出与导入。 |
| 删除有延迟 |
删除的笔记会先隐藏，30 天后才随清理永久移除；执行「立即清理」会立刻永久删除，无法撤销。 |
| 清单不可勾选 |
Markdown 清单会被渲染，但本版本不支持点击勾选，需要编辑文字改变状态。 |
| 渲染可能有差异 |
Markdown 预览使用通用渲染规则，不同版本或不同 App 的显示可能略有差异；网络图片不会加载。 |
| 附件占用空间 |
关闭「保留原图」后照片会被压缩（长边 2048 像素、JPEG 90%），该压缩不可逆。 |
4. Apple App Store 附加条款

- 许可范围。 第 5 条授予的许可仅限于你在拥有或控制的 Apple 品牌设备上、按 Apple 媒体服务条款中的使用规则使用本 App。
- 维护与支持。 开发者（而非 Apple）独自负责本 App 的维护与支持。Apple 无提供维护或支持的义务。

- 产品责任请求。 开发者（而非 Apple）负责处理与本 App 或你持有、使用本 App 有关的请求，包括产品责任、不符合法律或监管要求，以及消费者保护、隐私或类似法律项下的请求。
- 知识产权请求。 若第三方主张本 App 或你对它的持有与使用侵犯其知识产权，开发者（而非 Apple）独自负责调查、抗辩、和解与解决。
- 法律合规。 你声明并保证你不位于受美国政府禁运或被指定为「支持恐怖主义」的国家，也不在任何美国政府的禁止或限制方名单上。

Apple 的标准最终用户许可协议（apple.com/legal/internet-services/itunes/dev/stdeula）在与本协议不冲突的范围内并入本协议。

Terms of Use
Version 1.0 · Last updated 2026-10-25 · Effective date 2026-10-25
1. Agreement to these Terms
These Terms of Use ("Terms") are a legal agreement between you and Lu Li ("we", "us", "the Developer"), governing your use of the Lumen Notes mobile application and any updates, features or content we make available through it (the "App").
By downloading, installing or using the App, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the App and delete it.
2. Eligibility
You must be at least 13 years old (16 in the EEA/UK) to use the App. If you are a minor, you may use the App only with the involvement of a parent or guardian.
3. What the App does — and what it does not
Lumen Notes is a local Markdown notebook:
- write in Markdown and switch between editing and a clean preview;
- organize with
#tags (including #work/meeting hierarchies), pin and archive notes;
- search all notes and filter by tag;
- add image and file attachments, with duplicate images stored once;
- save drafts automatically and restore them after an interruption;
- export the whole library as a ZIP backup and import it on another device.
Limitations you acknowledge:
| Topic |
What you should know |
| The App is not a backup service |
Notes are stored on the device only. Deleting the App deletes notes and attachments unless you exported a backup or have a device backup. Export regularly and keep the file off the device. |
| Backups are not encrypted |
An exported ZIP is plain text: anyone who obtains the file can read your notes. Keep it safe and send it over a channel you trust. |
| No sync |
This version has no iCloud sync, multi-device sync, widgets, share extension or Siri integration. Moving to another device requires a manual export and import. |
| Deletion is delayed |
Deleted notes are hidden first and permanently removed by cleanup after 30 days; "Clean Up Now" removes them immediately and cannot be undone. |
| Checklists are not interactive |
Markdown checklists are rendered but cannot be tapped in this version; edit the text to change the state. |
| Rendering can differ |
Preview uses general Markdown rules, so display may vary between versions or apps; remote images are not loaded. |
| Attachments use storage |
With "Keep Original Images" off, photos are compressed (2048 px long edge, JPEG 90%); that compression cannot be reversed. |
4. Apple App Store additional terms
These Terms are between you and the Developer only, not with Apple. Apple is not responsible for the App or its content. The following applies because you obtained the App from the Apple App Store:
- Scope of licence. The licence granted in §5 is limited to a non-transferable licence to use the App on Apple-branded devices that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions.
- Maintenance and support. The Developer, not Apple, is solely responsible for providing any maintenance and support services for the App. Apple has no obligation to furnish any maintenance or support.
- Warranty. The Developer is solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) for the App. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App.
- Product claims. The Developer, not Apple, is responsible for addressing any claims relating to the App or your possession and/or use of it, including product liability claims, claims that the App fails to conform to any applicable legal or regulatory requirement, and claims arising under consumer protection, privacy or similar legislation.
- Intellectual property claims. In the event of a third-party claim that the App or your possession and use of it infringes that third party's intellectual property rights, the Developer, not Apple, will be solely responsible for the investigation, defence, settlement and discharge of the claim.
- Legal compliance. You represent and warrant that you are not located in a country subject to a U.S. Government embargo or designated by the U.S. Government as a "terrorist supporting" country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
- Third-party beneficiary. Apple and its subsidiaries are third-party beneficiaries of these Terms and, upon your acceptance, will have the right (and will be deemed to have accepted the right) to enforce these Terms against you.
- Export. You must comply with applicable export control and sanctions laws and may not use the App in any prohibited jurisdiction or for any prohibited purpose.
- U.S. Government end users. The App is a "Commercial Item" as defined in 48 C.F.R. §2.101, consisting of "Commercial Computer Software" and "Commercial Computer Software Documentation". It is licensed to U.S. Government end users only as Commercial Items and with only those rights granted to all other end users.
Apple's standard Licensed Application End User License Agreement (apple.com/legal/internet-services/itunes/dev/stdeula) is incorporated by reference to the extent it applies and does not conflict with these Terms.
5. Licence and restrictions
Subject to these Terms, we grant you a personal, limited, non-exclusive, non-transferable, revocable licence to use the App on Apple devices you own or control.
You may not:
- copy, modify, translate, reverse-engineer, decompile or disassemble the App, except to the extent permitted by mandatory law;
- rent, lease, sublicense, distribute or resell the App;
- remove or alter proprietary notices;
- circumvent any technical protection measure;
- use the App in a way that violates applicable law or Apple's terms.
We may suspend or terminate your licence if you materially breach these Terms.
6. Your content and responsibilities
You keep all rights to your notes and attachments. You grant us only the limited, on-device licence necessary to operate the features you invoke (for example, reading and writing the library or creating a backup). Because processing happens on your device, we never receive your content.
You are responsible for:
- the content of your notes and attachments, and your right to use any text, images or files in them;
- exporting backups regularly and keeping them safe, especially for important content;
- storing backups somewhere you trust — they are not encrypted;
- keeping your device and passcode safe.
7. Purchases
This version has no in-app purchases and is free. We process no payments, and there are no subscriptions or restores. If paid features are introduced later, the price and terms will be shown in the App before you confirm a purchase.
8. Free features
All current features are free with no usage limits.
9. Intellectual property
The App, including its software, design, text and graphics, is owned by the Developer or its licensors and is protected by copyright and other laws. These Terms do not grant you any rights other than the limited licence in §5.
"Lumen Notes" is a name used by us. Apple, iPhone, iPad, App Store and iCloud are trademarks of Apple Inc. Other names may be trademarks of their respective owners. The App includes open-source components (including ZIPFoundation, swift-markdown and MarkdownUI), distributed under their own licences.
10. Feedback
If you send us suggestions or feedback, you grant us a non-exclusive, perpetual, royalty-free, worldwide licence to use and incorporate it without compensation or attribution. Do not send us notes with sensitive content.
11. Privacy
Our Privacy Policy explains what the App processes on your device and what leaves it. By using the App you acknowledge that policy. The key point: your notes never leave your device unless you export or share them.
12. Disclaimer of warranties
To the maximum extent permitted by law, the App is provided "AS IS" and "AS AVAILABLE", without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, non-infringement, and uninterrupted or error-free operation.
We do not warrant that:
- the App will prevent any data loss, or that a backup will always be complete and restorable;
- Markdown will render identically in every app;
- the App will be compatible with every iOS version or device.
Some jurisdictions do not allow the exclusion of certain warranties, so some of the above may not apply to you.
13. Limitation of liability
To the maximum extent permitted by law, the Developer will not be liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for any loss of notes, attachments, data, profits, goodwill or business opportunity, arising out of or related to your use of or inability to use the App, even if advised of the possibility.
To the maximum extent permitted by law, the Developer's total aggregate liability for all claims relating to the App will not exceed the greater of (a) the amount you paid for the App in the 12 months preceding the claim, or (b) USD 10.
Nothing in these Terms limits liability that cannot be limited by law, or your mandatory statutory rights as a consumer.
14. Indemnity
To the extent permitted by law, you agree to indemnify and hold harmless the Developer from claims, damages, losses and expenses (including reasonable legal fees) arising from your breach of these Terms, your misuse of the App, or content you process that infringes the rights of others.
15. Termination
You may stop using the App and delete it at any time. We may suspend or terminate the licence if you breach these Terms or if we discontinue the App. On termination, the licence in §5 ends; §§4, 9, 12, 13, 14, 17 and 18 survive. Termination does not entitle you to a refund except where required by law or by Apple's refund policy.
16. Changes to the App and these Terms
We may update the App and these Terms from time to time. We will post the updated Terms with a new "Last updated" date and, for material changes, describe them in the App or on this page before they take effect. If you continue to use the App after the effective date, you accept the updated Terms.
17. Governing law and disputes
These Terms are governed by the laws of the People's Republic of China, without regard to conflict-of-law rules. Subject to the paragraph below, the courts of the People's Republic of China have exclusive jurisdiction over disputes arising from these Terms or the App.
Nothing in this section deprives you of the protection of mandatory consumer laws in your country of residence, or of your right to bring a claim in your local courts where the law gives you that right. Before filing a claim, please contact us at support@gougou.me so we can try to resolve the issue informally.
18. Miscellaneous
- Entire agreement. These Terms and the Privacy Policy are the entire agreement between you and us regarding the App.
- Severability. If any provision is held invalid, the remaining provisions remain in full force.
- No waiver. Our failure to enforce a provision is not a waiver.
- Assignment. You may not assign these Terms. We may assign them to an affiliate or successor.
- Language. These Terms are provided in English and Chinese. If they conflict, the English version controls to the extent permitted by applicable law.
- Apple. Apple is not a party to these Terms except as stated in §4.
