Privacy Policy

Effective date: October 27, 2026

Who we are

Greatvineis a product of Fountainhead Operations LLC ("we," "us"), providing AI-powered text messaging assistants for small businesses, reachable at https://greatvine.ai. This policy covers both visitors to this website and people who exchange messages with businesses that use Greatvine.

Information we collect

• Website:information you submit through our waitlist and contact forms (email address, name, business name, message), and the pages you visit here and on our signup pages at app.greatvine.ai, through the analytics and advertising tags described under "Cookies and advertising" below.
• Messaging service: when you text a business that uses Greatvine, we process the contents of that conversation, your phone number or chat identifier, and appointment details you provide (such as your name and requested time), on behalf of that business.
• Website chat: our chat widget stores a random session identifier in your browser so your conversation history persists. It is not used to track you across other sites.

How we use information

• To operate the messaging assistant: answering questions, booking appointments, and notifying the business you contacted.
• To generate transcripts and AI summaries of conversations for the business you messaged.
• To respond to your inquiries and manage the early-access waitlist.
• To secure, debug, and improve the service.

SMS / text messaging

• Conversations are customer-initiated: you opt in by texting a business's number. Businesses may also send appointment confirmations and reminders related to your request.
• Message frequency varies. Message and data rates may apply.
• Reply STOP at any time to opt out of messages from a business, and HELP for help.
• No mobile information will be shared with third parties or affiliates for marketing or promotional purposes. Text messaging originator opt-in data and consent are not shared with any third parties.

Greatvine for monday.com

If your team installs our app from the monday.com marketplace, calls are placed from inside monday and the app reads only what it needs to do that: the name of the item you open and the contents of the board column your account designates as the phone-number column, using your own monday permissions at the moment you view it. We do not copy or store your boards. What we do store are call records — the numbers involved, timestamps, duration, and voicemail recordings and their transcripts when a caller leaves one — together with the monday account and user identifiers needed to operate your subscription. Billing is handled entirely by monday.com; we never see your payment details. If you uninstall the app, we permanently delete your workspace's data — including call history and voicemail recordings — within 10 days, and your phone number is released.

Calendar and video conferencing connections

Businesses can connect their own Google Calendar, Microsoft Outlook, or Zoom account to Greatvine to power scheduling. When a business connects an account, we store the OAuth tokens for that connection encrypted at rest and use them only for the connected purpose: reading free/busy times and writing booking events (calendars), and creating, updating, or deleting the video meetings that belong to bookings (Zoom). We never read the contents of unrelated calendar events, and we never access Zoom meetings, recordings, or account data beyond creating the meetings a booking asked for. Disconnecting an account in settings deletes its tokens immediately, and deleting a Greatvine account deletes every connection with it. We request the minimum scopes each provider offers for this functionality.

Greatvine's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. From Google Calendar we request only the free/busy scope, which returns the times a calendar is busy and never the title, guests, location, or description of any event, and the events scope, which we use solely to create, update, and delete the booking events Greatvine itself makes. We do not use Google user data to train generalized AI models, we do not sell or transfer it for advertising, and no human at Greatvinereads it except with the account owner's explicit permission for support, or where required by law.

Sharing

We do not sell personal information. We share data only with the service providers required to operate Greatvine — messaging carriers and platforms (e.g., Twilio, Meta WhatsApp), cloud hosting and database providers, and AI model providers that process conversation text to generate replies and summaries — each bound to use it only to provide their service; with the business whose number or website you contacted, which controls its own customer relationships; and when required by law. Visits to this website and our signup pages are also reported to Meta to measure our own ads, as described below.

Cookies and advertising

This website and our signup pages use the Meta Pixel, a tag from Meta Platforms, to measure and improve our ads on Facebook and Instagram. It sets cookies in your browser and tells Meta which pages you viewed and whether you requested a demo or started a free trial, along with technical details such as your IP address and browser. Meta may link this to your Facebook or Instagram account under its own privacy policy. When we run Google ads, the Google tag reports demo requests and trial clicks to Google in the same way. We also use Vercel Web Analytics, which counts visits by page and referrer without cookies. None of these tags run inside the Greatvine app once you are signed in, and none of them see the calls or texts handled by Greatvine.

AI service providers

Greatvine's assistant is powered by third-party AI services. To answer calls and texts, book appointments, and produce transcripts and summaries, we send them the content of the conversations a business has on its Greatvine number — call audio, recordings, voicemails and transcripts; text messages, including replies a business sends from the Greatvine app; the customer details in those conversations (names, phone numbers, email addresses and appointment details); and the business information the assistant answers from (hours, services and knowledge-base content). The Greatvinemobile app shows this disclosure and asks for permission before it is used, and the permission can be withdrawn in the app under Settings → AI & your data.

• Anthropic (Claude) reads conversations and call transcripts to write replies, book appointments and summarize calls.
• OpenAItranscribes voicemail recordings, and indexes business knowledge and customers' questions so the assistant can find the right answer.
• ElevenLabsturns the assistant's replies into the voice callers hear.
• Twiliocarries calls and texts, and converts callers' speech to text during a live call.

Each of these providers processes this data on our behalf, under terms that require them to protect it to a standard at least equal to the one described in this policy and to use it only to provide their service to us. We do not sell this data or allow it to be used for advertising. A phone's own address book is read on the device by the mobile app and is never uploaded to us or to any of these providers.

Retention & security

Conversation data is retained for as long as the business you contacted maintains its account, so it can serve you in future conversations. Data is encrypted in transit and at rest, isolated per business, and access-controlled. You may request deletion of your data at any time (below).

Your choices

• Opt out of SMS from any business by replying STOP.
• Limit ads based on your visits here in Meta's ad preferences, or block third-party cookies and tags in your browser; the site works without them.
• Request access to or deletion of your personal information via our contact form.

Changes

We will post any changes to this policy on this page with an updated effective date.
