Categories of personal data processed

Each category below is Personal Data because it is held against an identified customer account. A device model or a data volume would not identify anyone on its own.

• First name
• Last name
• Email address
• MSISDN (mobile number)
• ICCID (SIM identifier, where linked to an individual)
• EID (device eSIM identifier, where linked to an individual)
• Device make and model, in some cases
• Job title and department, where the Customer provides them
• Mobile plan order and assignment information
• Credit or debit payment information (if provided)
• Connection and usage data, including data volumes and the countries and networks used
• Support and chat messages, and delivery metadata

Subprocessors and locations

AI subprocessors

The model providers behind Bedrock do not receive inputs or outputs, and no customer content is used to train models. No tracing or evaluation tool sits outside the tenant.

Data transfers

Personal data for PostFinance Travel eSIM is stored at rest in the EU. Our team in the UK administers and supports the service and has access to it. AI inference for this service runs on Amazon Bedrock inside Mindszi's private AWS account in the EU, so prompts and completions remain in the EU. Where a transfer to the US is needed for payments or website analytics, it relies on the EU standard contractual clauses, the UK International Data Transfer Addendum and, for data from Switzerland, the FDPIC-recognised clauses or the Swiss-US Data Privacy Framework where the provider is certified.

AI model training

Mindszi does not permit AI subprocessors to use customer content for model training or fine-tuning. For PostFinance Travel eSIM the assistant runs in Amazon Bedrock, where inputs and outputs are not shared with the model providers and are not used to train models, and we do not opt into any data-sharing, fine-tuning or feedback-driven training programme.
