App: Volta – Consumer
SDR places the highest value on the protection of your data. The mobile application “Volta – Consumer” is designed for consumers using the Portuguese Deposit Return System (DRS) to check whether an EAN code is eligible in the scheme and to find collection points for returning PET and can packaging
The app does not require user registration and is not intended to collect personal data about its users. SDR states that the app only collects anonymous diagnostic and technical information necessary to maintain app stability, security, and performance.
1. Controller for Data Processing
SDR Portugal – Associação de Embaladores (SDR)
Torre Zenith – Rua Doutor António Loureiro Borges, nº 9, Piso 11, Miraflores, 1495-131 Algés
NIPC: 516554999

Phone: 210195116
Email: geral@sdrportugal.pt
Data protection inquiries may be sent by email to geral@sdrportugal.pt or by post to the above address.
2. Data Processing in the App
SDR provides the application “Volta – Consumer” to enable consumers to:
- validate whether beverage packaging EANs are included in the Portuguese DRS scheme;
- view a map of available collection points for PET and can returns;
- consult collection point details such as address, map location, opening hours, and navigation options; and
- access general information, FAQs, and contact details about the Portuguese deposit return system.
In this context, SDR describes the following processing activities for the consumer app:
2.1. No user account or identification data
The app does not require account creation, login, or user profile management. SDR therefore does not intentionally collect user identification data such as name, surname, email address, or phone number through the app.
2.2. EAN validation
The app allows users to validate whether a beverage packaging EAN is part of the Portuguese DRS scheme. The EAN may be entered manually or captured by the device camera.
- The EAN code refers to a product identifier and is not, in itself, personal data.
- If the camera is used, image access is used only to read the barcode on the device. SDR does not intend to collect or store photos or video of the user for this purpose.
- The processing of the barcode-reading function is limited to providing the requested validation result.
2.3. Collection point map and navigation
The app displays collection points where consumers can return PET and can packaging within the Portuguese DRS system, including address, map location, opening hours, and navigation information.
- The collection point information relates to participating return locations, not to the user.
- If the user opens navigation through a third-party map or navigation service, that provider may process data independently under its own privacy terms.
- According to the information provided for this draft, SDR does not collect user location data through the app.
2.4. Anonymous diagnostic data
SDR states that the app only collects anonymous diagnostic and technical data. This information is used exclusively to operate, secure, maintain, and improve the app.
- Such information may include app version, device type, operating system version, crash logs, performance events, and similar technical diagnostics.
- This information is intended to be anonymous and not to identify the user personally.
- Where data is truly anonymous, the GDPR does not apply to that information as personal data.
3. Legal Bases
Based on the information provided for this consumer app draft:
- use of the app functions requested by the user, such as barcode validation and display of collection-point information, may be considered necessary to provide the requested service;
- anonymous diagnostic data is used for app security, stability, and improvement; and
- where any device permission is required, such as camera access for barcode scanning, access depends on the permission settings chosen by the user on the device.
This section should be confirmed by SDR’s legal team before publication, particularly if any analytics or SDK provider is used in production.
4. Recipients of Data
Only authorized persons and contracted service providers may have access to data processed for operating the app, where applicable.
- Sensoneo j.s.a., Company ID 50 746 057, Kollarova 27, 84106 Bratislava, Slovakia (IT service provider; processor under Art. 28 GDPR, where applicable);
- Microsoft Ireland Operations Limited, One Microsoft Place, South County Business Park, Leopardstown, Dublin 18, Ireland (IT service provider; processor under Art. 28 GDPR, where applicable). Any transfer to the USA, in particular to Microsoft Corporation, is stated to rely on the EU-US Data Privacy Framework, where applicable.
- Apple Inc. and Google LLC may process data independently when the app is downloaded, installed, updated, or used via the App Store or Google Play.
SDR does not control processing carried out independently by Apple, Google, or any external map/navigation provider. Their own privacy policies apply to such processing.
5. Automated Decision-Making
SDR does not use automated decision-making within the meaning of Art. 22 GDPR.
6. Data Security
SDR implements appropriate technical and organizational measures designed to protect processed data and app infrastructure. These measures may include access controls, logging, backups, firewalls, and other security mechanisms proportionate to the risks involved.
7. Your Rights
Where personal data is processed, users have the rights granted under the GDPR, including the right of access, rectification, erasure, restriction, portability, and objection, subject to the legal conditions of each right. Users may also lodge a complaint with the Portuguese Data Protection Authority (Comissão Nacional de Proteção de Dados – CNPD).
8. Data Retention
Because the app is described as not collecting user personal data and only using anonymous diagnostic data, no retention period for identified user data is intended to apply. If any technical logs that could qualify as personal data are generated in exceptional circumstances, SDR should define and publish the applicable retention period before launch.
