These Terms of Service ("Terms") are an agreement between you and Shih-Fu ("Shih-Fu", "we", "us"), based in the United States. By creating an account or using Shih-Fu (the "Service") you agree to these Terms and to our Privacy Policy. If you use the Service for a business, you confirm that you are at least 18 years old and have the authority to bind that business. If you do not agree, do not use the Service.
Shih-Fu helps service businesses keep their customers: it stores customer and service records, schedules and sends reminders and promotional messages, offers a quick check-in form, takes appointment bookings through links in messages, and shows how those messages perform. We may improve, change or remove features over time.
You must give accurate information and keep it up to date. Keep your password secret. You are responsible for everything done through your account, so tell us promptly if you think it has been misused. You can sign out of all devices, change your password, or delete your account in Account Settings.
You decide who to message and what to say, and you are responsible for it. You must have the permission the law of your country and your customers' countries requires before you message someone on a channel. That includes rules on marketing messages, consent, opt-out and data protection, such as the TCPA and CAN-SPAM in the United States, the GDPR and ePrivacy rules in Europe and the UK, CASL in Canada, and local telecom rules such as TRAI in India. Shih-Fu records the consent choices you enter, only sends on the channels you mark, and stops messaging anyone you remove, but we do not check that your consent is valid. Honour every request to stop. Do not message people you have no relationship with, and do not upload purchased or scraped lists.
You agree not to use the Service to:
We may remove content or suspend an account that breaks these rules.
Messages are delivered through providers such as Google (Gmail), Meta (WhatsApp) and Twilio (SMS). They have their own terms, approval steps, fees and limits, and they can refuse or delay messages. Shih-Fu is not responsible for their services, and delivery is not guaranteed. When you connect your Google account, Google's terms apply to that connection as well as these Terms.
You own your data, including your customer records. You give us permission to use it only to provide the Service as described in the Privacy Policy. For personal information about your customers, we act as your processor (service provider) and agree that we will:
You confirm that you have a lawful basis to give us your customers' information and that your use of the Service complies with the law that applies to you. If your law requires further terms for transfers of data between countries, such as the EU Standard Contractual Clauses, contact us and we will put them in place.
New accounts start with a 30 day free trial, with no payment card needed. If we introduce paid plans, we will show you the price and what is included before you are charged, and we will never charge you without your agreement. We may change prices for future periods with at least 30 days notice.
The Service, including its software, design and content, belongs to us and our licensors. We give you a limited, non-exclusive, non-transferable right to use it for your own business while these Terms apply. If you send us feedback, we may use it without owing you anything.
We work to keep the Service available but do not promise it will be uninterrupted or error-free. We may carry out maintenance or change features. Please keep your own copies of anything critical to your business.
You can stop using the Service and delete your account at any time. We may suspend or end your access if you break these Terms, put the Service or other people at risk, or if the law requires. When an account is deleted, its data is deleted as described in the Privacy Policy. Sections that by their nature should continue (such as ownership, liability and governing law) continue after the Terms end.
The Service is provided "as is" and "as available". To the fullest extent the law allows, we disclaim all warranties, including that the Service will be uninterrupted or error-free, that messages will be delivered or read, or that it will bring you any particular results, bookings or revenue.
To the fullest extent the law allows, Shih-Fu will not be liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, revenue, data or goodwill, arising from your use of the Service. Our total liability for any claim relating to the Service is limited to the greater of the amount you paid us in the 12 months before the claim and 100 US dollars. Nothing in these Terms limits liability that cannot be limited by law.
You agree to cover our reasonable losses and costs arising from claims by third parties (including your customers and regulators) that result from the messages you send, your instructions, your breach of these Terms, or your breach of the law. This does not apply where we caused the claim.
The Service is available to businesses worldwide, and you are responsible for following the laws that apply where you operate and where your customers are. These Terms are governed by the laws of the United States and of the state in which Shih-Fu is established, without regard to conflict of law rules, and disputes will be brought in the state or federal courts located in that state. Nothing in these Terms limits any right you have under mandatory consumer or data protection law where you live.
We may update these Terms. We will give account owners at least 14 days notice of material changes, by email or in the Service. If you keep using the Service after the changes take effect, you accept them. If you do not agree, you can delete your account.
