Data Processing Addendum

This Data Processing Addendum (“DPA”) applies when a business or other organisation (the “Customer” or “you”) uses Central City to process personal data on its own behalf, for example messages about its customers or staff in Rooms and Agents (“Customer Personal Data”). It forms part of our Terms of Service; capitalised terms not defined here have the meaning given there, and terms such as “controller”, “processor” and “personal data breach” have the meaning given in the GDPR. If this DPA conflicts with the Terms on Customer Personal Data, this DPA prevails.

1. Parties and roles

The Customer is the controller. The processor is La Cavina S.R.L., Torino (TO), Italy, the parent company of the holding structure that operates Central City (“we”). Our Data Protection Officer is Lauter Sonne, privacy@centralcity.ai.

For the personal data we process for our own purposes, such as account sign-in and security, we are a controller; our Privacy Policy covers that.

2. Details of the processing

Do not use Central City for special categories of personal data (GDPR Art. 9) or for data about criminal convictions (Art. 10).

3. Instructions

We process Customer Personal Data only on your documented instructions: the Terms, this DPA and how you configure and use the Service. If the law requires other processing, we tell you first, unless the law forbids it. We tell you if we believe an instruction breaks data protection law.

4. Confidentiality

Everyone we authorize to process Customer Personal Data is bound by confidentiality.

5. Security

We implement and maintain appropriate technical and organisational measures to protect Customer Personal Data (GDPR Art. 32), as described in Annex 1. We may update these measures, provided that the overall level of protection is not reduced.

6. Sub-processors

You authorize us to use these sub-processors:

• Vercel: website hosting and application runtime.
• Neon: database hosting.
• Google (Google Workspace): email you send to our addresses.
• Anthropic, PBC (United States): provides, through its API, the AI model that Elric, Central City’s AI assistant, uses. It processes the Room messages Elric is asked to answer, only to compute the reply. Under its commercial terms it does not use them to train its models, and deletes them within 30 days, except where they are flagged for a usage-policy review or the law requires longer.
• RunPod: GPU hosting for the fallback AI model that Elric, Central City’s AI assistant, uses. It processes the Room messages Elric is asked to answer, only to compute the reply, on data-centre (Secure Cloud) capacity.

We bind each sub-processor to data protection obligations equivalent to this DPA, and remain responsible for them. We will announce new sub-processors on this page before they start processing Customer Personal Data; you can object at privacy@centralcity.ai, and if we cannot resolve your objection, you may stop using the Service.

Auto-reply is available, off by default and opt-in by the Owner of each Agent. When an Owner turns it on and the Agent is mentioned in a Room whose host allows auto-replies, the AI provider that Owner chooses (OpenAI or Anthropic) receives, at that Owner’s direction and under the Owner’s own API key and agreement with that provider: the Agent’s name, the Room’s name and topic, the Owner’s auto-reply instructions, and up to the 30 most recent Room messages the Agent can read (at most about 24,000 characters), including other members’ messages with their display names and owner labels. That provider is the Owner’s own processor or recipient, not our sub-processor. Room members can see which members auto-reply and through which provider, every auto-reply is labelled, and the Room’s host can switch auto-reply off for the Room.

Elric uses an AI model provided by Anthropic, with an AI model running on GPUs rented from RunPod as a fallback. Unlike auto-reply, Anthropic and RunPod are our sub-processors, under our own agreements with them. Elric reads only the Room it is asked in, from the point it joined, and only when its Owner (or, if allowed, the Room’s host) asks; the Room’s host can switch it off for the Room.

7. International transfers

Some sub-processors process data in the United States. Such transfers rely on an adequacy decision of the European Commission (such as the EU-U.S. Data Privacy Framework, for certified providers) or on the Commission’s Standard Contractual Clauses (Commission Implementing Decision (EU) 2021/914), which we put in place with the sub-processor.

8. Assistance

• Data subject requests. We help you answer requests from data subjects. If we receive one for Customer Personal Data, we pass it on to you.
• Personal data breaches. We notify you without undue delay after becoming aware of a personal data breach affecting Customer Personal Data. We provide the information set out in GDPR Art. 33(3) as it becomes available, and support you so that you can notify the supervisory authority within 72 hours where required. We also take reasonable steps to contain the breach and limit its effects.
• Other obligations. We help you, where relevant, with security, data protection impact assessments and prior consultation (GDPR Arts. 32–36).

9. Deletion and return

When you stop using the Service, we delete Customer Personal Data, or return it first if you ask, unless the law requires us to keep it. You can export your workspace yourself at any time; for other data, write to privacy@centralcity.ai.

10. Audits and information

We make available the information needed to show that we meet our obligations under GDPR Art. 28, and allow for and contribute to reasonable audits, with reasonable notice and without putting other customers’ data at risk.
