Privacy Notice: Data Processor Addendum
Ref: TTS-PNA-001 | Version: 1.0 | Date: March 2026
This addendum supplements the main Tayside Technical Services Ltd privacy notice. It sets out how TTS processes personal data in its capacity as a Data Processor on behalf of its clients.
1. Who We Are
Tayside Technical Services Ltd ("TTS") is a technology company registered in Scotland. TTS provides AI-powered customer support, content generation, and lead generation infrastructure to business clients.
TTS is registered with the Information Commissioner's Office (ICO) as a data processor. Our ICO registration number is available on request.
Our data protection contact is Scott Simmons, Director. For all data protection queries please write to: scott@taysidetech.com
2. Our Role as Data Processor
Where TTS provides services to business clients ("Controllers"), TTS acts as a Data Processor under UK GDPR. This means:
- TTS processes Personal Data only on the documented instructions of the relevant client
- TTS does not determine the purposes or means of processing -- those decisions rest with the client as Controller
- TTS does not use Personal Data processed on behalf of clients for any other purpose
- TTS is bound by a Data Processing Agreement with each client governing how their data is handled
3. What Personal Data TTS Processes as Processor
The Personal Data TTS processes as a Data Processor depends on the services in scope. For customer support chat deployments, this typically covers:
| Category | Examples | Source |
|---|---|---|
| Contact details | Name, email address, phone number | Submitted voluntarily by user |
| Communication data | Chat transcript content | Generated during chat session |
| Technical data | IP address, browser type | Collected automatically by Crisp.chat |
| Knowledge base content | Business content provided by client for storage in Firestore | Provided directly by client |
! TTS systems are configured to prevent Special Category Data from being processed by the AI layer. Automatic escalation to a human agent is triggered if such content is detected in any user message.
4. Sub-Processors
In delivering services, TTS uses the following sub-processors. All sub-processors operate under data processing agreements and process data within the European Economic Area:
| Sub-Processor | Purpose | Location |
|---|---|---|
| Crisp.chat | Chat interface and transcript storage | Amsterdam / Frankfurt (EU) |
| Google Vertex AI | AI response generation | EU region |
| Google Cloud Firestore | Knowledge base storage | EU region |
5. Data Retention
TTS holds Personal Data only for the period specified in the relevant Data Processing Agreement. For customer support deployments, chat transcripts and contact details are retained for 90 days unless the client requests otherwise or asks for earlier deletion. Knowledge base data is held for the duration of the contract.
On termination of any client agreement, all Personal Data is removed from TTS-accessible systems within 30 days.
6. Data Subject Rights
Data Subjects wishing to exercise their rights under UK GDPR (access, rectification, erasure, restriction, portability, or objection) in relation to Personal Data that TTS processes on behalf of a client should contact the relevant client as Data Controller in the first instance.
Where a Data Subject contacts TTS directly, TTS will forward the request to the relevant Controller within 5 working days and inform the Data Subject that this has been done.
7. Security
TTS maintains appropriate technical and organisational measures to protect Personal Data. Full details are set out in the TTS Technical and Organisational Measures document (Ref: TTS-TOM-IE-001), available on request from scott@taysidetech.com.
