Privacy Policy

Last updated: 7 October 2026

At GAME CHANGER ZAGREB 5.0, powered by the CoreEvent platform, we value your privacy and are committed to protecting your personal data. This Privacy Policy explains what data we collect, how we use it, who we share it with, and what rights you have when you use this App.

This App is provided by Wolf Media d.o.o. (“Organizer”) for GAME CHANGER ZAGREB 5.0, and is technically operated by CoreEvent d.o.o., Dunjevac 15, 10000 Zagreb, Croatia, OIB: 36611335369 (“CoreEvent”), which hosts the App, its database and servers on the Organizer’s behalf.

Who Is Responsible for Your Data

The Organizer is the data controller for personal data processed to run the Event and the App (registration, agenda interactions, networking, chat, feedback) and determines the purposes of that processing.
CoreEvent acts as data processor, processing personal data on the Organizer’s behalf and instructions, and provides the technical infrastructure (hosting, database, security, push notifications) the App runs on.
Where you give separate, specific consent directly to CoreEvent, CoreEvent acts as controller only for that specific processing.

Information We Collect

When you use the App, we may collect:

Account information — name, email address, company, job title and profile photo;
Event information — saved sessions, interests, agenda selections and interactions within the App;
Networking & communication data — chat messages (text and voice), chat requests, favourites and feedback you submit;
Ticket & check-in data — your ticket/QR code and session check-ins/attendance;
Profile links — the LinkedIn and website addresses you choose to add, shown on your profile so others can reach you;
Technical information — device type, operating system, app usage data, crash/performance logs and push-notification token;
Settings & preferences — your choices about sharing your email, receiving messages and appearing on the attendee list.

We do not collect payment card data in the App; ticket payments are processed separately by the Organizer’s ticketing provider.

How We Use Your Information

We use your information to:

provide access to Event features and services (agenda, tickets, check-in);
manage your account and Event participation;
personalize your Event experience, including the matchmaking suggestions you request in the App;
enable networking and communication between attendees, speakers and sponsors;
send push notifications about sessions, schedule changes, chat requests and Event announcements;
maintain the security, stability and performance of the App;
comply with our legal obligations and enforce our Terms of Use.

Legal Basis for Processing

We process your personal data on the following legal bases under the GDPR:

performance of a contract — e.g. providing you with App access and Event features;
your consent — e.g. sharing your email with other attendees, receiving marketing notifications — you may withdraw consent at any time via Settings;
legitimate interest — e.g. App security, preventing abuse, improving the App;
legal obligation, where applicable.

Your Privacy Choices

In the App’s Settings, you can control:

Email — whether your email address is visible to other attendees;
Receive messages — whether other attendees can message you;
Attendee list — whether you appear in the public list of attendees.

These settings let you decide, beyond the minimum needed to run the Event, what is shared with other attendees. Turning a setting off does not delete data already shared before you changed it.

We may share your information with:

the Organizer, who uses it to run the Event and may contact you about it;
other attendees, speakers and sponsors — but only information you choose to share via your profile and Settings (e.g. when you make your email visible or accept a chat request);
service providers supporting the App on our behalf — hosting/cloud providers, push-notification providers (e.g. Firebase/APNs) and analytics providers — under confidentiality and data-processing agreements;
authorities, where required by law, to protect our rights, or to prevent fraud or security incidents.

We do not sell your personal data.

International Data Transfers

Some of our service providers (e.g. push notification or analytics providers) may process data outside the European Economic Area. Where this happens, we rely on appropriate safeguards, such as the European Commission’s Standard Contractual Clauses, to protect your data.

Data Retention

We retain your personal data for as long as necessary to provide the App during the Event and for a reasonable period afterward (typically up to 12 months), unless a longer period is required by law or by the Organizer’s own retention obligations (e.g. accounting or dispute purposes). Chat messages and networking data are retained for the duration of the Event and deleted or anonymized after the App is decommissioned for that Event, unless you request earlier deletion.

Data Security

We apply appropriate technical and organizational measures to protect your data against unauthorized access, loss or misuse, including encrypted data transmission and access controls on our servers and database. No system is completely secure, and we cannot guarantee absolute security.

Your Rights

Subject to applicable law (including the GDPR), you have the right to:

access the personal data we hold about you;
request correction of inaccurate data;
request deletion of your data (“right to be forgotten”);
request restriction of processing;
receive your data in a portable format;
object to processing based on legitimate interest or for direct marketing;
withdraw consent at any time, without affecting the lawfulness of processing before withdrawal;
lodge a complaint with your national data protection authority (in Croatia: Agencija za zaštitu osobnih podataka – AZOP).

To exercise these rights, contact us using the details below or use the relevant controls in Settings. You can delete your conference profile yourself via Settings → Delete account.

Children’s Privacy

The App is not intended for children under 16. By registering, you confirm that you are at least 16 years old.

Changes to This Privacy Policy

We may update this Privacy Policy from time to time, in particular to reflect changes to the App’s features, service providers or applicable law. We will notify you of material changes via the App.
