Terms of Service

Effective 2026-10-16. Provided in English and Simplified Chinese; if they differ, the English version controls.

The short version. This summary is for convenience; the full Terms below are what apply.

Nestbill helps you and the people you live with record shared bills and see who owes whom. It never holds or moves money.

What you enter stays yours. People in a shared Nest can see that Nest's bills, photos and payment details.

Receipt scanning sends the photo you choose to an AI service and can make mistakes, so check the result before saving.

Nestbill is in public beta and is provided "as is". Export your ledgers if you need your own copy.

1. Agreement

Nestbill (also called 巢记) is a bill-splitting service for roommates and households, offered on the web and in the Nestbill app. It is operated by the operator of this Nestbill service ("we", "us"). These Terms of Service ("Terms") are a binding agreement between you and us. By creating an account, accepting these Terms in the app, or using Nestbill, you agree to these Terms and acknowledge our Privacy Policy. If you do not agree, do not use Nestbill.

2. Who can use Nestbill

You must be at least 13 years old. If you are under the age of majority where you live, you may use Nestbill only with the permission of a parent or legal guardian who agrees to these Terms for you. Nestbill is not directed to children under 13.

3. Your account

Give accurate information when you sign up, and keep your password (at least 12 characters) secret. You are responsible for activity under your account.
One person per account. Do not share, sell or transfer your account.
Tell us promptly if you believe someone else has used your account. You can sign out other devices and change your password under Me → Account security.
There is currently no email-based recovery. If you lose your password, we restore access manually after verifying your identity, as described in Account help.

4. Ledgers and shared Nests

Your personal ledger is visible only to your account.
In a shared Nest, every signed-in member can see the Nest's bills, the photos and proofs attached to them, and the payment methods members add. Nest admins can manage members, exchange rates and group funds.
Anyone holding an invitation link can use it to join. Share invitations only with the people they are meant for.
When you add other people to a Nest, including guests without an account, enter only information you are entitled to share and that they would expect to appear in a shared household ledger.
If you leave or are removed from a Nest, your access ends but the Nest's past bills and confirmations remain, because the other members rely on them.

5. Your content

You keep all rights to the bills, notes, names, photos and other material you submit ("Your Content"). You give us a worldwide, non-exclusive, royalty-free license to host, store, back up, copy, process and display Your Content only as needed to run Nestbill for you and for the members of the Nests you share it with, including sending a receipt photo to the AI provider when you ask us to scan it. This license ends when Your Content is deleted, except for copies other Nest members still rely on and short-lived backups. We do not sell Your Content or use it for advertising.

You are responsible for Your Content. Do not upload anything unlawful, anything that infringes someone else's rights, other people's private information without their permission, or malicious code.

6. Receipt scanning with AI

Receipt scanning is optional. A photo is sent only when you take or choose a picture and tap to scan it.
The photo, together with your ledger's base currency, is sent to the AI service this server is configured to use, currently DeepSeek. DeepSeek is a company based in the People's Republic of China and processes requests on its own servers under its own terms.
AI results can be wrong: items, prices, quantities, discounts or tax may be misread. Nothing is saved until you review it, and you are responsible for checking the result against the receipt.
The photo is attached to the bill you save. Scans are limited per account per month, and we may change the limit or the provider, or turn the feature off.
Do not scan documents carrying more than an ordinary receipt does, such as full card numbers or identity documents.

7. Not a bank, payment service or adviser

Nestbill records amounts and calculates who owes whom. It does not hold, collect, transfer or pay money, and it never initiates bank or card payments. You and the other members settle up yourselves, outside Nestbill. Exchange rates are entered by Nest admins and may be out of date or wrong. Balances, splits and conversions are tools to help you keep track; they are not financial, tax or legal advice.

8. Acceptable use

You agree not to:

use Nestbill for anything unlawful, fraudulent or harassing;
access or try to access another person's account or a Nest you were not invited to;
probe, scan or test the vulnerability of the service, or interfere with or overload it;
scrape Nestbill with automated tools, or copy, modify or reverse engineer it except where the law allows this despite this restriction;
get around scan limits, storage limits, rate limits or other restrictions, or resell access to Nestbill.

9. Paid features

Nestbill is free today. Personal and roommate basics are intended to stay free. We may later offer a one-time "Pro" purchase and a small subscription for AI features. Prices and what each includes will be shown before you buy.

Purchases made in the iOS app are processed by Apple under Apple's terms. Refunds are handled by Apple under its policies.
Subscriptions renew automatically at the end of each period unless you cancel at least 24 hours before it ends in your Apple account settings. Deleting the app does not cancel a subscription.
If we raise the price of a subscription, we will tell you in advance, and where required we will ask for your consent before the new price applies.

10. Beta, limits and availability

Nestbill is in a public beta. Features may change or be removed. The service has limits, including 128 MB of attachments per ledger, 8 MB per image, and caps on sign-ups and invitations. We do not promise that Nestbill will be uninterrupted, error-free or always available. We keep rolling backups for a limited time, but you should export your ledgers (CSV) regularly if you need your own records.

11. Ending your use

You may stop using Nestbill at any time and ask us to delete your account as described in the Privacy Policy. We may suspend or end your access if you break these Terms, if your use creates risk or legal exposure for us or other users, or if we stop offering Nestbill. Where reasonable we will tell you first and give you a chance to export your data. Sections 5, 7 and 12 to 18 survive termination.

12. Third-party services

Nestbill relies on third parties such as our hosting provider, the AI provider for receipt scanning and, for the iOS app, Apple. Their services are governed by their own terms, and we are not responsible for them.

13. Disclaimers

To the fullest extent permitted by law, Nestbill is provided "as is" and "as available", without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, title, non-infringement and accuracy. We do not warrant that calculations, exchange rates or AI results are correct, or that your data will never be lost.

14. Limitation of liability

To the fullest extent permitted by law, we will not be liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for lost profits, revenue, data or goodwill, arising from or related to Nestbill. Our total liability for all claims related to Nestbill is limited to the greater of the amount you paid us in the 12 months before the claim and US$50. Some jurisdictions do not allow these limits, so they may not apply to you. Nothing in these Terms limits liability that cannot be limited by law, such as for fraud, gross negligence or willful misconduct.

15. Indemnity

To the extent permitted by law, you will indemnify us against third-party claims and resulting costs arising from Your Content or your breach of these Terms.

16. Governing law and disputes

Please contact us first; we will try to resolve any dispute informally within 30 days. These Terms are governed by the laws of the place where the operator is established, without regard to its conflict-of-law rules. Nothing in these Terms takes away rights you have under the mandatory consumer protection laws of the place where you live, including the right to bring a claim in your local courts where those laws allow it.

17. Changes to these Terms

We may update these Terms. We will post the new version here with a new effective date. If a change is material, we will ask you to accept the new Terms in the app before you continue. If you do not accept, you may stop using Nestbill and ask us to delete your account.

18. Apple App Store

If you downloaded Nestbill from the Apple App Store, the following also applies:

These Terms are between you and us, not Apple. We, not Apple, are responsible for the app and its content.
Your license to use the app is limited to Apple-branded devices you own or control, as permitted by the App Store Usage Rules.
Apple has no obligation to provide maintenance or support for the app.
If the app fails to conform to an applicable warranty, you may notify Apple, and Apple will refund the purchase price, if any. To the maximum extent permitted by law, Apple has no other warranty obligation for the app.
We, not Apple, are responsible for addressing claims relating to the app, including product liability claims, claims that the app fails to meet legal or regulatory requirements, consumer protection and privacy claims, and claims that the app infringes someone's intellectual property.
You confirm that you are not located in a country subject to a U.S. Government embargo or designated as a "terrorist supporting" country, and that you are not on any U.S. Government list of prohibited or restricted parties.
Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

19. General

These Terms and the Privacy Policy are the entire agreement between you and us about Nestbill. If any part is found unenforceable, the rest stays in effect. Our not enforcing a provision is not a waiver. You may not assign these Terms without our consent; we may assign them in connection with a transfer of the service, and will tell you if we do.

20. Contact

Questions about these Terms: contact the operator of this Nestbill service through the person who invited you, or as described in Account help.

你在 Nest 中添加他人（包括没有账号的临时成员）时，只能录入你有权分享、且对方预期会出现在共享家庭账本里的信息。
你离开或被移出 Nest 后，访问权限终止，但该 Nest 的历史账单与核对记录会保留，因为其他成员仍需依赖这些记录。

5. 你的内容

你对提交的账单、备注、名称、照片等内容（“你的内容”）保留全部权利。你授予我们一项全球范围、非独占、免费的许可，仅为向你及你所分享 Nest 的成员提供巢记所需，托管、存储、备份、复制、处理和展示你的内容，包括在你要求识别时将小票照片发送给 AI 服务商。你的内容被删除后，该许可终止，但其他 Nest 成员仍依赖的副本和短期备份除外。我们不会出售你的内容，也不会将其用于广告。

你对你的内容负责。请勿上传违法内容、侵犯他人权利的内容、未经同意的他人隐私信息或恶意代码。

6. AI 拍小票

拍小票为可选功能。只有当你拍照或选图并点击识别时，照片才会被发送。
照片连同账本主币种会发送给本服务器配置的 AI 服务，目前为 DeepSeek。DeepSeek 是一家位于中华人民共和国的公司，会在其自己的服务器上按其条款处理请求。
AI 结果可能出错，商品、价格、数量、折扣或税费都可能识别错误。识别结果在你核对前不会保存，你有责任对照小票核对。
照片会附在你保存的账单上。每个账号每月的识别次数有限，我们可能调整次数、更换服务商或关闭该功能。
请勿扫描内容超出普通小票的文件，例如完整卡号或身份证件。

7. 不是银行、支付服务或顾问

巢记只记录金额、计算谁欠谁。它不保管、收取、转移或支付任何资金，也从不发起银行或银行卡扣款。你和其他成员需在巢记之外自行结清。汇率由 Nest 管理员录入，可能过时或有误。余额、分摊和换算只是帮助你记账的工具，不构成财务、税务或法律建议。

8. 使用规范

11. 停止使用

你可以随时停止使用巢记，并按隐私政策所述申请删除账号。如你违反本条款、你的使用给我们或其他用户带来风险或法律责任，或我们停止提供巢记，我们可以暂停或终止你的访问。在合理情况下我们会事先通知，并给你导出数据的机会。第 5、7 条及第 12 至 18 条在终止后继续有效。

12. 第三方服务

巢记依赖第三方服务，例如托管服务商、拍小票所用的 AI 服务商，以及 iOS App 涉及的 Apple。这些服务受其各自条款约束，我们不对其负责。

13. 免责声明

在法律允许的最大范围内，巢记按“现状”和“现有”提供，不作任何明示或默示的保证，包括适销性、特定用途适用性、所有权、不侵权及准确性的保证。我们不保证计算、汇率或 AI 结果正确，也不保证你的数据绝不会丢失。

14. 责任限制

在法律允许的最大范围内，对于因巢记引起或与之相关的任何间接、附带、特殊、后果性、惩戒性或惩罚性损害，以及利润、收入、数据或商誉损失，我们不承担责任。我们就与巢记相关的全部索赔承担的总责任，以你在索赔前 12 个月内向我们支付的金额与 50 美元两者中较高者为限。部分司法辖区不允许上述限制，因此可能不适用于你。本条款不限制依法不得限制的责任，例如欺诈、重大过失或故意不当行为。

15. 赔偿

在法律允许的范围内，对于因你的内容或你违反本条款而引起的第三方索赔及由此产生的费用，你应向我们作出赔偿。

16. 适用法律与争议

请先联系我们，我们会尽量在 30 天内友好解决争议。本条款受运营者设立地的法律管辖，不适用其冲突法规则。本条款不剥夺你依所在地强制性消费者保护法律享有的权利，包括在该法律允许时向当地法院起诉的权利。

17. 条款变更

我们可能更新本条款，并在此发布新版本和新的生效日期。如变更属于重大变更，我们会请你在 App 中同意新条款后再继续使用。如你不同意，可以停止使用巢记并申请删除账号。

18. Apple App Store

Apple 没有义务为 App 提供任何维护或支持。
如 App 不符合适用的保证，你可以通知 Apple，Apple 将退还购买价格（如有）。在法律允许的最大范围内，Apple 对 App 不承担其他保证义务。

你确认你不位于受美国政府禁运或被认定为“支持恐怖主义”的国家，也不在任何美国政府禁止或限制交易的名单上。
Apple 及其子公司是本条款的第三方受益人，可以向你执行本条款。

19. 其他

本条款与隐私政策构成你与我们之间关于巢记的完整协议。任何部分被认定无法执行的，其余部分仍然有效。我们未执行某项条款不构成弃权。未经我们同意，你不得转让本条款；我们可因服务转让而转让本条款，并会通知你。
