5. AI-Powered Quality Assurance
To maintain a high-quality marketplace, Zinn Hub uses AI-powered tools to assist with quality assurance of service listings published by freelancers (Zinners). This process works as follows:
- What is processed: Listing content including titles, descriptions, pricing, package details, categories, tags, FAQs, and portfolio/sample information. No personal identity data, payment details, or private messages are sent for AI analysis.
- How it is used: The AI evaluates listing quality against marketplace standards and provides scores, improvement suggestions, and actionable feedback to help freelancers improve their service visibility and buyer appeal.
- Who provides the AI: AI quality analysis is powered by Anthropic's Claude, a third-party AI service. Listing content is transmitted securely to Anthropic's API for processing. Anthropic's data handling is governed by their own privacy and data policies.
- Data retention: AI-generated scores and feedback are stored as part of the listing metadata on Zinn Hub. The listing content sent to the AI is not permanently stored by the AI provider after processing, and is not used by the provider to train its AI models.
5A. AI Translation, Live Calls & Automated Data Processing
Zinn Hub is a multilingual platform and uses automated and AI-powered systems to translate content, enable cross-language communication, and provide optional AI-assisted tools. This section explains what data those systems process, who processes it, and how it is protected. The legal status of translated content — including which language version is authoritative in a dispute — is set out in Section 24A of our Terms and Conditions.
5A.1 Automated Translation of Content
So that users who do not share a common language can transact, the platform automatically translates content across the languages it supports. Content that may be sent for automated translation includes service listings, Micro Zinns, Project briefs, Proposals, Custom Offers, Freelancer Profiles, portfolio descriptions, reviews, and messages exchanged between users. Where content has been translated, a "show original" option is generally available so you can view the original text.
- Who provides it: Automated translation is powered by Google Cloud (Vertex AI, using Google's Gemini models). Content is transmitted securely to Google Cloud for processing and is subject to Google's data-processing terms.
- Legal basis: Performance of our contract with you (providing the core cross-language marketplace), together with our legitimate interests in operating a global platform.
- Training: Content sent for translation is used solely to produce the translation and is not used by the provider to train its AI models.
5A.2 Real-Time Translation on Live Calls
Where you use Zinn Hub's live audio or video calls with translation enabled, your call audio and speech are processed in real time to generate live captions and, where enabled, spoken-voice translation. Because this involves voice data, we treat it with particular care.
- Who provides it: Real-time captions and voice translation are powered by Google Cloud speech and translation services (Speech-to-Text, Translation, and Text-to-Speech). Call audio and speech are transmitted securely to Google Cloud for real-time processing.
- Retention: Call audio and the resulting captions and translations are processed transiently to provide the feature during the call. Zinn Hub does not retain call audio, captions, or transcripts after the call ends, except where necessary to resolve an active dispute or where required by law.
- Legal basis: Performance of our contract with you, together with our legitimate interests in enabling cross-language communication.
- Training: Call audio and speech are not used by the provider to train its AI models.
5A.3 AI-Assisted Creation Tools
Zinn Hub provides optional AI-assisted tools — including the AI Zinn Creator, AI Micro Creator, Self-Promo Studio, and Import My Services — that generate draft listings, promotional copy, and imported content from information you provide. When you use these tools, the information you enter (and, for Import My Services, the source listing content you supply) is sent to a third-party AI provider to generate the output. Nothing is published without your review. Content sent to these tools is used solely to generate your output and is not used by the provider to train its AI models.
5A.4 International Transfers for AI Processing
Our AI service providers operate internationally, and content sent to them for translation, live-call processing, creation tools, or quality assurance may be processed outside the United Kingdom. Where this occurs, we rely on the safeguards described in Section 11 (International Data Transfers).
5A.5 Third-Party AI Providers Do Not Train on Your Data
5A.6 Our Own Internal Support Assistant
Before any support-ticket content is used to train or improve this internal assistant, it is anonymised: personal identifiers (such as names, email addresses, and other details that could identify an individual) are stripped out, so that the training data does not identify you. This is the only category of your data that Zinn Hub itself uses for AI training, and it is used only in this anonymised form.
- Legal basis: Our legitimate interests in improving the speed and quality of our customer support.
- Your rights: You may object to this processing at any time under Section 9 by contacting us at [email protected].
6. Payment Data
Zinn Hub does not directly store your full credit card numbers, bank account details, or cryptocurrency wallet addresses. All payment processing is handled by our third-party payment providers (Stripe, PayPal, NOWPayments). These providers process your payment data in accordance with their own privacy policies and applicable payment industry standards (including PCI-DSS where applicable).
We may store partial payment identifiers (e.g. last four digits of a card, PayPal email address, or cryptocurrency network type) for transaction reference and customer support purposes.
7. Data Retention
We retain your data only as long as necessary for the purposes stated in this policy:
| Data Type | Retention Period |
|---|---|
| Account data | For the lifetime of your account and up to 90 days after deletion (unless legally required to retain longer) |
| Project & transaction data | At least 7 years to comply with tax and regulatory requirements |
| Marketing preferences | Until you opt out or withdraw consent |
| Support correspondence | Up to 3 years after resolution, unless related to an ongoing dispute |
| Translated content | Retained for as long as the original content it relates to (e.g. the underlying message, listing, or order) |
| Live-call audio & captions | Not retained after the call ends, except where needed to resolve an active dispute or as required by law |
| Internal assistant training data | The underlying support tickets follow the "Support correspondence" period above; data used to train our internal support assistant is retained only in anonymised form |
| AI quality scores & feedback | For the lifetime of the associated service listing |
| Ambassador referral data | For the duration of programme participation plus 12 months |

10. Data Security
We implement appropriate technical and organisational measures to protect your personal data against unauthorised access, alteration, disclosure, or destruction. These measures include:
- HTTPS encryption across the entire platform
- Encrypted storage of sensitive data at rest
- DDoS protection and web application firewall via Cloudflare
- Role-based access controls limiting internal data access

- Secure API communications with all third-party service providers
While we take all reasonable steps to protect your data, no system is completely secure. We encourage you to use strong, unique passwords and protect your login credentials.
11. International Data Transfers
Zinn Hub is based in the United Kingdom but serves users globally. Your data may be transferred to and processed in countries outside the UK, including by our third-party service providers who operate internationally. This includes content sent to our AI service providers (see Section 5A) — such as Google Cloud, which processes content for automated translation and real-time call translation — which may be processed outside the United Kingdom.
Where your data is transferred outside the UK, we ensure that appropriate safeguards are in place, such as the UK International Data Transfer Agreement (IDTA), the UK Addendum to the EU Standard Contractual Clauses (SCCs), an adequacy decision, or another lawful transfer mechanism in accordance with UK GDPR.
12. Children's Privacy
Zinn Hub is not intended for use by children under the age of 16. We do not knowingly collect personal data from anyone under 16 years of age. If you believe that a child has provided personal information to us, please contact us immediately at [email protected] and we will take steps to delete that information.
