8. Processing of Web Shop Orders

If you place an order in our web shop, AION sense Kft. as data controller processes the data necessary to fulfil your order for the purposes and on the legal bases set out below. We neither request nor process health data for web shop purchases. Placing an order requires an AION user account (email address and password); the order is linked to that account and its email address. If you order a subscription in the web shop, your payment card is stored by Stripe Payments Europe, Ltd. for the later recurring charges; we do not receive your card details in this case either. The MAC address (unique device identifier) of the wristband is linked to your order when it is packed, and to your user account when it is first paired in the app.

Purposes, data processed and legal bases:

  • Fulfilment of the order (conclusion and performance of the contract): name, email address, phone number, ordered products and quantities, order total, order number, customer note and the time of acceptance of the Terms and Conditions. Legal basis: Article 6(1)(b) GDPR – performance of a contract.
  • Delivery: name, phone number, email address, delivery address (postal code, city, street, house number) or the identifier and name of the selected parcel locker, and the tracking number. These data are transferred to the selected delivery provider (Magyar Posta Zrt. – MPL, GLS General Logistics Systems Hungary Kft. or FOXPOST Zrt.). Legal basis: Article 6(1)(b) GDPR – performance of a contract.
  • Invoicing and compliance with accounting obligations: billing name and address, tax number for business purchases, invoice line items and amounts, invoice number, method and date of payment. Legal basis: Article 6(1)(c) GDPR – compliance with a legal obligation (Act CXXVII of 2007 on VAT and Act C of 2000 on Accounting).
  • Processing the payment: the identifiers of the payment transaction in the case of card payment. We never receive or store your card details; these are processed by Stripe Payments Europe, Ltd. Legal basis: Article 6(1)(b) GDPR.
  • Handling withdrawals, warranty and guarantee claims and complaints: the order data, the content of your notification and – in the case of a refund – your bank account number. Legal basis: Article 6(1)(c) GDPR – legal obligation (Government Decree 45/2014 (II. 26.), Government Decree 151/2003 (IX. 22.), Act CLV of 1997 on Consumer Protection).
  • Fraud prevention and enforcement of legal claims: technical data and logs related to the order. Legal basis: Article 6(1)(f) GDPR – our legitimate interest in preventing fraud and enforcing our claims.

Providing these data is a precondition of entering into the contract: without them we cannot fulfil your order. Web shop order data are retained until the claims arising from the contract become time-barred (generally 5 years under the Hungarian Civil Code), invoices and accounting documents for 8 years from issuance, and the record of a consumer complaint together with our reply for 5 years. The full list of data processors is set out in Section 4, and your rights are described in Section 7.
