ChatAssistant for Windows Terms of Service

Last updated: 19 October 2026

ChatAssistant only replies to people who write to you. It is not a bulk-messaging or advertising tool, and WhatsApp may restrict numbers that abuse automation.

1. Acceptance

These terms govern the use of ChatAssistant for Windows (the “app”), published on the Microsoft Store as “ChatAssistant - Business” by Web Business Tools (Blasmani Titi) (“we”). By installing or using the app you accept these terms and the Privacy policy. If you do not agree, do not use the app.

2. What the app is

ChatAssistant is an independent tool that sends automatic replies in your one-to-one WhatsApp chats according to the rules you create: keywords, a welcome message, exact phrases you send, a campaign that replies to any message (with a per-customer pause of the days you choose) and follow-ups. It works through WhatsApp Web, inside the app, as a linked device of your own account and on your own PC.

• It is not a WhatsApp or Meta service, and it does not use the official WhatsApp Business Platform (API).
• It only replies in chats where someone wrote to you, or where you sent one of your exact phrases, and the follow-ups you set up only go to those same chats. It offers no bulk sending, broadcasts or messages to people who did not write to you.
• It comes with sample content from a fictitious store, “Kusi Accesorios”, so you can try it right away. Replace it with your own information and files before turning the service on with real customers.
• “Test assistant” lets you try your rules on the PC without linking any account and without sending anything.
• The free version includes every feature, with no ads, and sends up to 70 automatic replies per day. The optional ChatAssistant Pro subscription removes that daily limit (see “ChatAssistant Pro subscription” below).

3. ChatAssistant Pro subscription

• What it includes. Pro removes the free version’s limit of 70 automatic replies per day; everything else works the same in both versions. A reply is counted once for each sequence of a rule or follow-up sent to a customer, not per message; test mode and “Test assistant” never count. Without Pro, when the limit is reached the assistant stops replying until midnight (your PC’s time). Your own “Daily reply limit”, if lower, still applies with Pro.
• Plan and price. Pro is sold only through the Microsoft Store, as a monthly subscription that renews automatically. The price, in your currency and with any applicable taxes, is shown in the app and in the Microsoft Store before you confirm, and Microsoft charges it to the payment method of your Microsoft account.
• Free trial. The subscription may start with a 7-day free trial for Microsoft accounts that have not used it before. If you cancel before the trial ends, you are not charged; otherwise the monthly price is charged when the trial ends and then every month.
• Automatic renewal and cancellation. The subscription renews at the end of each period until you cancel it in your Microsoft account (https://account.microsoft.com/services). Cancelling stops future renewals; Pro stays active until the end of the period already paid. Uninstalling the app does not cancel the subscription.
• Failed payments. If a renewal cannot be charged, Microsoft may give you time to update your payment method; meanwhile, or if it is not fixed, Pro may stop and the free limit applies again.
• Refunds. Payments and refunds are handled by Microsoft under the Microsoft Store policies. Unless those policies or the law say otherwise, a period that has already started is not refunded. You can also write to us and we will help you with the request.
• Price changes. We may change the subscription price. Microsoft notifies existing subscribers in advance, under the Microsoft Store rules, before a new price applies to them.
• Your Microsoft account. Pro is tied to the Microsoft account you bought it with. On another PC with the same account, use “Restore purchase” in the app. Pro does not change the risks to your WhatsApp number described below.

4. Requirements

• Being 18 or older and legally able to accept these terms.
• Using a WhatsApp account that is yours or that you are authorized to manage, and having the phone with that account at hand to link the PC.
• A PC with Windows 10 (version 2004 or later) or Windows 11, with the Microsoft Edge WebView2 Runtime and an internet connection. The assistant only replies while the PC is on, online and not asleep.

5. Acceptable use

By using ChatAssistant you agree to:

• Only reply to people who write to you. Use the app to answer messages from your own customers, not to start conversations with people who did not contact you.
• Not send spam. No bulk, unsolicited or repetitive messages, chain messages or advertising nobody asked for, and no attempts to get around the app’s limits to send at scale.
• Follow WhatsApp’s terms. Respect WhatsApp’s Terms of Service and policies (including the WhatsApp Business ones when they apply to you) and the laws that apply to you, such as personal data protection, consumer protection and advertising laws.
• Respect opt-outs. Honor requests from people who do not want automatic messages and handle your customers’ data lawfully.
• Supervise the assistant. Check your chats regularly. The app does not replace a person and may not reply in some cases (no connection, PC off or asleep, or changes in WhatsApp Web).
• Act within the law. Do not use the app to impersonate anyone, deceive or harass people, or for illegal purposes.

6. Your content

You are solely responsible for the content of your rules (texts, images, videos, audio, voice notes and documents) and for everything sent on your behalf. You must have the right to use that content, and it must not be illegal, misleading or offensive or infringe other people’s rights. The content stays on your PC; we do not see, review or store it.

7. Risks to your WhatsApp number

• WhatsApp does not officially authorize unofficial tools or automated messaging, and may restrict, suspend or ban your number if it detects use it considers contrary to its terms. The only Meta-approved way to automate messages at scale is the official WhatsApp Business Platform.
• ChatAssistant includes measures to reduce that risk (it only replies to people who write to you, anti-spam pauses, natural delays, a daily reply limit and an opt-out option), but it cannot guarantee that your number will not be restricted.
• WhatsApp Web may change at any time and make the app stop working, fully or partly, until it is updated.

You use ChatAssistant at your own risk.

8. No warranties

The app is provided “as is” and “as available”. To the fullest extent permitted by law, we do not guarantee that it will work without interruptions or errors, that it will reply to every message, that it will be compatible with every computer or that its results will meet your needs.

9. Limitation of liability

To the fullest extent permitted by law, the developer is not liable for indirect, incidental or consequential damages, or for the loss of sales, customers, data or opportunities, for the restriction or ban of your WhatsApp number, or for the content sent through your rules. Nothing in these terms limits the rights the law grants you as a consumer that cannot be waived.

10. License to use

We grant you a personal, non-exclusive, non-transferable and revocable license to use the app on your devices under these terms and the Microsoft Store terms of use. You may not sell, rent or redistribute it, or distribute modified versions as if they were ChatAssistant. The open-source components it includes are governed by their own licenses, which you can see in the app in Settings › About › Open source licenses.

11. Trademarks

“ChatAssistant” and its logo identify this app. ChatAssistant is not affiliated with, endorsed or sponsored by WhatsApp LLC or Meta Platforms, Inc. WhatsApp is a trademark of WhatsApp LLC and is mentioned only to describe compatibility. Microsoft, Windows and the Microsoft Store are trademarks of Microsoft Corporation.

12. Ending use

You can stop using ChatAssistant whenever you want: log out of WhatsApp Web in Settings and uninstall the app. If you have ChatAssistant Pro, also cancel the subscription in your Microsoft account. We may modify, suspend or stop offering the app or some of its features. If you breach these terms, you must stop using the app.

13. Changes to these terms

We may update these terms. The current version is always available in the app, in Settings › Terms of service, with its update date; if a change is important, we will tell you in the app. If you keep using ChatAssistant after a change, you accept the new version.

14. Governing law

These terms are governed by the laws of the Republic of Peru. Any dispute will be submitted to the judges and courts of Lima, without prejudice to the rights and remedies the law grants you as a consumer.
