NexusCaller

AI Phone Receptionist — Data Processing Agreement

Version 1.3 · Effective October 24, 2026 · between the customer ("Controller") and NexusCaller LLC ("Processor")

This agreement forms part of the Terms of Service and is accepted together with them. It governs NexusCaller's processing of personal data of people who call the customer's phone line on the customer's behalf, under Article 28 of the EU General Data Protection Regulation (GDPR) and as a "service provider" under the California Consumer Privacy Act (CCPA/CPRA). A countersigned copy is available on request to info@nexuscaller.com.

1. Processing on instructions

The Processor processes callers' personal data only to provide the AI Phone Receptionist, on the Controller's documented instructions — its settings in the Service and these terms — unless required otherwise by law, in which case it will inform the Controller where permitted. The Processor immediately informs the Controller if, in its opinion, an instruction infringes the GDPR or other applicable data protection law.

2. Purpose limitation

The Processor will not sell or share the data, will not use it for its own purposes (including training AI models or advertising), and will not combine it with data from other customers or sources, except as needed to provide the Service.

3. Confidentiality

Persons authorized to process the data are bound by confidentiality, and access is limited to what is needed to operate and support the Service.

4. Security

The Processor implements the measures in Annex 2 and keeps them appropriate to the risk.

5. Sub-processors

The Controller authorizes the sub-processors listed in the Privacy Policy (including Vapi and Twilio for telephony and voice AI, and the speech-recognition, voice and AI-model providers used through them). The Processor imposes equivalent data protection obligations on them, remains responsible for them, and gives at least 30 days' notice of any new sub-processor, during which the Controller may object; if the objection cannot be resolved, the Controller may terminate the affected Service.

6. Assistance

The Processor helps the Controller respond to data-subject requests (including a tool to find and delete all calls for a phone number or email address), and with security, breach notification and data protection impact assessments, taking into account the nature of the processing.

7. Personal data breaches

The Processor notifies the Controller without undue delay, and in any event within 72 hours, after becoming aware of a personal data breach affecting the Controller's data, with the information reasonably available. For California personal information, the Processor notifies the Controller immediately after discovery.

8. Deletion and return

Call records, recordings, transcripts and summaries are deleted automatically 12 months after the call, in the Processor's systems and at Vapi. When the Service ends, the Processor deletes the Controller's data within 30 days, after the Controller has had the opportunity to retrieve it, unless law requires keeping it.

9. Information and audits

The Processor makes available the information necessary to demonstrate compliance, in the first instance by answering a reasonable security questionnaire once a year. On-site audits, where required by law, are at the Controller's cost and on reasonable notice.

10. International transfers

Data is processed in the United States. Where GDPR applies, transfers are governed by the European Commission's Standard Contractual Clauses (Decision 2021/914, the "SCCs"), which are incorporated by reference, with the Controller as data exporter and the Processor as data importer: Module 2 (controller to processor) and, where the Controller acts as a processor for another controller, Module 3 (processor to processor). For the SCCs: Clause 7 (docking clause) applies; under Clause 9, option 2 (general written authorization) applies, and the Processor gives at least 30 days' notice of any new sub-processor, during which the Controller may object; under Clause 13, the competent supervisory authority is the one competent for the Controller; for Clause 17 (governing law) and Clause 18 (courts), the law and courts of the Republic of Ireland apply, unless the Controller's Member State is required. Annexes 1 and 2 of this agreement and the sub-processor list in the Privacy Policy provide the information for the SCCs' annexes. If this agreement conflicts with the SCCs, the SCCs prevail. A copy of the SCCs is available on request at info@nexuscaller.com.

11. Controller's responsibilities

The Controller is responsible for having a lawful basis for the processing, including for recording calls; for complying with call-recording and consent laws (such as all-party-consent rules) beyond the fixed spoken AI and recording notice the Service plays at the start of every call; for its own privacy notice to callers, which should mention that its line is answered by an AI assistant and recorded; for the content and instructions of its receptionist; and for not instructing the collection of sensitive data over the phone.

12. California (CCPA) service-provider terms

Where the CCPA applies, the Processor is the Controller's service provider, and the Controller discloses personal information to it only for the limited and specified business purpose of providing the Service described in Annex 1. The Processor:

The Controller may take reasonable and appropriate steps to ensure that the Processor uses the personal information consistently with the Controller's CCPA obligations and, on notice, to stop and remediate unauthorized use.
