Who we are
Wharfline Technologies LLC ("Wharfline", "we", "us") provides a managed AI phone receptionist service to business clients. When we handle calls on behalf of a business client, that business is generally the controller of its callers' information, and we act as its service provider, processing that information to deliver the service. You can reach us at support@wharfline.com.
Information we process
- Caller information: the caller's phone number, name, and any details a caller provides during a call (such as appointment details or the reason for calling).
- Call audio and transcripts: calls handled by the AI receptionist are recorded and transcribed so we can answer questions, book appointments, and send call summaries. The receptionist is built to tell callers this at the start of every call (see "Call recording" below).
- Business client information: account, contact, billing, and configuration details from the businesses we serve.
- Website information: details submitted through forms on this site, and standard technical and usage data, including the website analytics described below.
How we use information
We use information to operate the receptionist, book appointments, send call summaries to the business, provide support, maintain security, and improve the service. We do not sell personal information.
Website analytics
Our public website at wharfline.com uses Cloudflare Web Analytics to understand how our pages perform and how many people visit them. It sets no cookies and stores nothing on your device. It records the address of the page you are on, the page that referred you, your browser and device type, the country a visit comes from, and how quickly the page loaded. Cloudflare receives your IP address with the request, as it does for any page it serves, and does not keep it for analytics. We do not use this to identify you, and we do not use it for advertising. Cloudflare may process this data outside the country you are in. The signed-in client portal at portal.wharfline.com is not measured.
Call recording
Calls handled by the AI receptionist are recorded and transcribed to provide the service. The receptionist is built to speak a recording notice at the start of every call, before any other handling, and we are responsible for configuring and keeping it that way. The notice tells callers that the line is recorded. The only calls with no recording are those a caller ends before the assistant answers. Recording-consent requirements vary by location; some jurisdictions require all parties to be informed, which the start-of-call notice is designed to satisfy. Business clients are responsible for ensuring call handling and any forwarding complies with the laws that apply to them and their callers.
Text messages
We do not send text messages from Wharfline's own phone lines. If you call our sales line or our demo line, we will not text you.
Texts from businesses we serve. Some of our business clients may choose to text their callers, for example to confirm a booking. When a client does, the messages are sent in that business's name, under that business's own registration with the mobile carriers, and only to callers who agree to receive them during the call. We send them on the business's behalf as its service provider. That business's own privacy policy governs its text message program. Today, no business we serve sends text messages through us.
Stopping messages and getting help. Reply STOP to any text message to stop receiving them, or reply HELP for help. When we receive an opt-out on a client's behalf, we honor it. Message and data rates may apply. You can also email support@wharfline.com.
Your mobile number. No mobile information will be shared with third parties or affiliates for marketing or promotional purposes. Text messaging originator opt-in data and consent will not be shared with any third parties.
If you are a business client
If you are one of our business clients, our Data Processing Addendum at wharfline.com/data-processing sets out how we handle your callers' information for you, in more detail than this Policy does. It forms part of your Service Agreement. Where the Addendum and this Policy differ on how your callers' information is handled, the Addendum controls between you and us, because it is the document you accepted. This Policy tells your callers and the public how we handle information generally.
Service providers (sub-processors)
We share information with companies who help us run the service. They process information only to provide their services to us.
Who we engage directly. Retell AI (voice platform), Twilio (telephony), Supabase (data storage), Cal.com (scheduling), Resend (email delivery), Stripe (payments and billing), Google Workspace (email), Cloudflare (hosting, and cookieless analytics on our public website), Formspree (website forms), and Tally (onboarding forms).
Who they engage in turn. The voice platform reaches speech, language and logging providers of its own to do the actual work of a call. That chain is longer than the list above, it is maintained by the platform rather than by us, and it changes. It is published at trust.retellai.com/subprocessors and that link, not a copy of it, is the disclosure. We link the maintained list rather than reprinting a snapshot because a copied list is accurate on the day it is written and silently wrong afterwards, and this one can change on fifteen days' notice.
Data retention
Call recordings and transcripts (together, "Call Data") are retained for twenty-four (24) months from the date of the call, unless a different period is agreed in writing with the business client, and are deleted after that. We also delete Call Data sooner on request, or after account closure, unless a longer period is required to comply with law or resolve disputes. Account and billing records are kept as required.
Security
We use reasonable administrative and technical measures to protect information. No method of transmission or storage is perfectly secure.
Your choices
Individuals may request access to or deletion of their information by emailing support@wharfline.com. For caller information we process on a business's behalf, we may direct the request to that business.
Children
The service is not directed to children.
Changes & contact
We may update this policy and will post the new date above. Questions? Email support@wharfline.com.
