1. How to read this register
This register describes the providers used to deliver the service. A provider processes your information only where used for the selected service. It is not a certification that each provider is active in production. Before activating a customer’s service, Linevio confirms the providers, products, processing locations, and data-protection terms applicable to that service. No exclusive U.S. residency or certification is implied.
Our service providers may act as subprocessors for customer call data or as independent controllers for limited functions such as their own payment compliance. Customer-controlled integrations are separately identified. Changes affecting customer personal information follow the notification and objection process in the Data Processing Addendum.
2. Supabase — application data and authentication
Purpose: database, authentication, and private application storage. Information may include customer account and business configurations, approvals, call metadata and summaries, protected transcript data where configured, uploaded source files, and audit records. Processing locations, retention, and backup settings are documented for the applicable service before activation.
3. OpenAI — AI processing
Purpose: live speech interaction and supported analysis of approved setup materials. Information may include live audio, call context, transcripts, approved business facts, and document excerpts needed for setup assistance when enabled. Selected products and contractual settings determine provider retention; do not assume that an application storage setting guarantees zero provider retention. Production provider terms must support the data-use restrictions in the Data Processing Addendum.
4. Retell — applicable phone-agent lines
Purpose: voice-agent and call handling on lines configured to use Retell. Information may include caller and destination numbers, live audio, approved instructions, call metadata, transcripts, and recordings only where separately approved. A line using another voice path does not necessarily use Retell. Any separate telephony or SIP carrier engaged for the production voice path must also be identified before activation.
5. Stripe — subscriptions and payments
Purpose: secure checkout, subscriptions, invoicing, payment processing, fraud prevention, and billing compliance. Information may include business contact and billing details, payment details submitted directly to Stripe, subscription identifiers, and metered usage totals. Full call transcripts are not needed for payment processing. Stripe’s role may differ by activity and is governed by the applicable payment and privacy terms.
6. Resend — transactional email
Purpose: service, setup, billing, and support emails. Information may include recipient contact details, message content, private service links, and delivery events. Email may contain limited account or call-outcome information where that notification is enabled; it is not a reason to include unnecessary sensitive caller data.
7. Website, worker hosting, and telephone infrastructure
Vercel provides website and application hosting; Railway hosts the persistent voice worker. Hosting providers process application traffic, request and security metadata, and service data needed by the hosted components. The voice worker processes live call context and protected recovery records. Applicable telephone or SIP carriers and their processing roles are identified for the customer’s service before phone activation.
8. Customer-authorized services
Cal.com: where the customer connects its account, the service checks approved availability, creates confirmed bookings, and reschedules verified future bookings. Data may include attendee name, email, booking reference, time, and appointment details. Appointment cancellation remains with the customer’s team. The service order identifies whether the account is customer-contracted or Linevio-contracted.
Compatible CRM endpoint: where approved, the customer’s chosen HTTPS endpoint receives the supported structured completed-call outcome, not a full transcript. The customer chooses and authorizes that recipient and governs its later use under its own agreement.
Customer’s existing carrier: the customer retains its public number and authorizes forwarding. The carrier handles its own network and account information under the customer’s carrier agreement. Additional Linevio-contracted carriers belong in the production register described above.
