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 AR Measure 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），并在所在国家达到可同意隐私政策所述处理的年龄。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
AR Measure 在你的 iPhone 或 iPad 上使用相机与传感器进行测量：
- 以 AR 测量距离、链式总长、面积、高度与角度；
- 显示估算的误差范围与测量条件提示；
- 提供气泡水平仪与倾角测量，并可将设备校准到已知水平面；
- 提供声级计，显示 dB(A)、dB(C)、dB(Z)、平均值、最大值与倍频程；
- 保存、命名、备注、收藏、搜索测量记录，并支持公制 / 英制单位。
你必须了解的限制：
| 事项 |
你需要知道 |
| AR 结果是估算 |
测量基于相机与运动传感器，不是激光测距。条件良好时典型误差约为 1%（带 LiDAR）或 1–3%（不带 LiDAR），距离越远、光线越差、角度越陡，误差越大。 |
| 不能替代专业测量 |
涉及施工、装修、家具购买、结构安全或其他关键尺寸时，请用卷尺或专业仪器复核。我们不对依据本 App 结果作出的决定负责。 |
| 声级计未经计量校准 |
iPhone 麦克风没有做声压校准，读数只是近似值，不能用于职业健康、法律、合规或噪声执法测量。校准只能减小偏差，不构成计量认证。 |
| 水平仪需要校准 |
设备传感器可能存在偏差。请在使用前于已知水平面上执行「设为零点」。 |
| 平面图功能不可用 |
本版本不提供房间扫描或平面图生成；该入口只显示说明。 |
| 本 App 不是备份服务 |
记录只保存在本机。删除 App 会删除记录，除非你另有设备备份。 |

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 AR Measure 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, and old enough in your country to consent to the processing described in the Privacy Policy. 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
AR Measure uses the camera and sensors of your iPhone or iPad to measure:
- distances, chained totals, areas, heights and angles in AR;
- an estimated error range and guidance about the measuring conditions;
- a bubble level and tilt angle, which you can calibrate to a surface you know is level;
- an approximate sound level in dB(A), dB(C) or dB(Z), with average, maximum and octave bands;
- saved, named, annotated, favourited and searchable records, in metric or imperial units.
Limitations you acknowledge:
| Topic |
What you should know |
| AR results are estimates |
Measurements come from the camera and motion sensors, not a laser. Under good conditions the typical error is about 1% with LiDAR and 1–3% without; it grows with distance, poor light and steep angles. |
| Not a substitute for professional measuring |
For construction, renovation, furniture purchases, structural safety or any critical dimension, verify with a tape measure or a professional instrument. We are not responsible for decisions based on the App's results. |
| The sound meter is not calibrated for compliance |
The iPhone microphone is not calibrated for sound pressure. Readings are approximate and must not be used for occupational health, legal, compliance or noise-enforcement measurements. Calibration reduces bias but is not metrological certification. |
| The level needs calibration |
Device sensors can drift. Set zero on a surface you know is level before relying on the level. |
| No floor plan feature |
This version does not scan rooms or create floor plans; the entry only shows an explanation. |
| The App is not a backup service |
Records are stored on your device only. Deleting the App deletes them unless you have a device backup. |
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 to harass, stalk or spy on anyone, or to measure a private space you are not entitled to enter;
- 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 measurement records, notes and thumbnails. You grant us only the limited, on-device licence necessary to operate the features you invoke. Because processing happens on your device, we never receive your content.
You are responsible for:
- measuring only in places you are entitled to be, and respecting the privacy and property of others;
- verifying results before building, buying or making decisions based on them;
- keeping an independent device backup of records that matter to you;
- 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, free trials or restores. If paid features are introduced later, the price and terms will be shown in the App before you confirm a purchase, and these Terms will be updated.
8. Free features
All current features are free with no daily limits. We may change the feature set in future updates but will not retroactively charge for features already provided free of charge.
9. Intellectual property
The App, including its software, design, text, graphics and trademarks, 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.
"AR Measure" is a name used by us. Apple, iPhone, iPad, App Store and LiDAR are trademarks of Apple Inc. Other names may be trademarks of their respective owners. The App is not affiliated with or endorsed by Apple.
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 confidential information.
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: camera images and audio are never saved or uploaded.
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, accuracy, and uninterrupted or error-free operation.
We do not warrant that:
- measurements will be accurate to any particular tolerance or fit for any particular purpose;
- sound meter readings will match any standard instrument or be usable for compliance, legal or occupational-health purposes;
- the level will be accurate on any device without calibration;
- the App will be compatible with every iOS version, device or environment.
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 data, records, 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 (for example, liability for death or personal injury caused by negligence, or for fraud), 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 your measuring in a space you were not entitled to enter or in a way that infringed the privacy or property 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. If you do not agree, stop using the App and delete it.
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 and supersede any prior agreement on that subject.
- 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.
