3. Purpose and Legal Basis for Processing

4. Data Processing by Artificial Intelligence

4.1 Automatic response generation

The service uses third-party language models (LLMs) to generate responses that mimic your communication style. Data sent to these models includes:

• Your personality context and example messages
• Recent conversation history with each contact
• Response categories you have configured

Every contact who receives a reply generated this way is told beforehand, inside the conversation, that they may be talking to an artificial intelligence assistant. See section 14.

4.2 Screenshot analysis (Vision AI)

When you upload screenshots, they are processed using Google Gemini Vision to extract exclusively writing style characteristics (tone, emoji usage, typical length, vocabulary). The system is configured to NOT extract real names, phone numbers, emails, URLs, or any personally identifiable information. Only synthetic examples of writing style are generated.

Google processes these images in accordance with its Data Processing Addendum and the Gemini API Additional Terms.

4.3 Automated decisions

The service makes automated decisions about:

• Whether or not to respond to a message (intent classification)
• Whether to hand off the conversation to the creator (purchase intent detection)
• The category of each received message
• Automated filtering of messages considered spam or unwanted, which may not receive a response from the Service

These decisions do not produce legal effects on the user's contacts. The creator can review and modify any decision from the dashboard.

5. Data Processors (Third Parties)

We share data with the following providers, all of which have GDPR-compliant data processing agreements:

Note: When logging in via Google OAuth or Telegram Login, these providers share basic authentication data (email, name) with Twinyx in accordance with their own privacy policies.

Note on AI providers: Only one LLM provider is used at a time, configurable by the system administrator. Message data is sent to the active provider to generate responses and is not retained by these providers beyond request processing, in accordance with their respective data processing agreements.

6. International Data Transfers

Some of our data processors are located in the United States. These transfers are covered by:

• Data Privacy Framework (DPF): For providers certified under the EU-US Data Privacy Framework (European Commission adequacy decision of July 10, 2023).
• Standard Contractual Clauses (SCCs): For providers not certified under DPF, in accordance with European Commission Decision 2021/914.

7. Data Retention

7.1 Data in Multiple Telegram Accounts

If you connect multiple Telegram accounts to your Twinyx account (available for Pro users), data for each Telegram account is stored in isolation. This includes conversation history, categories, excluded contacts, and settings. Data retention policies apply per account: when you remove a connected Telegram account, only the data associated with that account is deleted.

8. User Rights

Under the GDPR and LOPDGDD, you have the right to:

• Access: Request a copy of all your personal data.
• Rectification: Correct inaccurate or incomplete data.
• Erasure ("right to be forgotten"): Request the deletion of your data when it is no longer necessary.
• Restriction of processing: Request the restriction of the use of your data in certain circumstances.
• Portability: Receive your data in a structured, machine-readable format.
• Objection: Object to processing based on legitimate interest.
• Withdrawal of consent: Withdraw consent at any time, without affecting the lawfulness of prior processing.
• Not to be subject to automated decisions: Request human intervention in decisions that significantly affect you.

14. Information for Telegram Contacts (Art. 14 GDPR)

When a contact sends a message to a creator using Twinyx, we process certain contact data to provide the auto-response service:

Data processed

• Telegram user identifier (telegram_user_id)
• Telegram username (if available)
• Content of messages sent to the creator
• Operational interaction classification (lead_temperature: cold/warm/hot)

Legal basis: Creator's legitimate interest (Art. 6.1.f GDPR) to manage their communications efficiently.

Purpose: Data is used exclusively to generate automated responses on behalf of the creator. The lead_temperature classification is an operational per-interaction categorization, not a persistent profile of the contact.

Retention: Data is retained while the creator's account is active, plus 30 days after deletion. Message history is automatically purged after 365 days and capped at the most recent 50 or 200 messages per contact depending on the plan.

AI interaction notice (Art. 50 AI Act)

Before the first automatically generated reply, we send the contact a message inside the conversation itself telling them that replies may come from an artificial intelligence assistant. The notice is sent once per contact and is active on every account: the creator can reword it, but cannot switch it off.

So the notice is not repeated on every message, we record that it was delivered: the contact's Telegram identifier, the date and time of the send, and a copy of the text delivered. That copy is kept unchanged even if the creator later edits the wording, because it is the evidence that the contact was informed and of what they were told. This data is retained while the creator's account is active and is deleted along with it.

Rights: Telegram contacts may exercise their rights of access, rectification, erasure, objection, and portability by contacting admin@twinyx.app
