Last updated: 8 June 2026

1. Introduction

This Privacy Policy explains how nerdik ("we", "us", or "our") collects, uses, and protects your personal data when you use our website and services (the "Service").

The data controller is Piotr Kurpiewski, operating nerdik. If you have questions about this policy or your data, contact us at support@nerdik.app.

2. Data we collect

We may collect the following categories of personal data:

Account data: email address, password (stored in hashed form), nickname, display name, timezone, and notification preferences.
Profile data: avatar image and other optional profile information you choose to provide.
User content: events, activities, organizations, places, descriptions, images, and other content you create or upload.
Usage data: participation in activities, interests, proposals, and interactions with other users through the Service.
Technical data: IP address, browser type, device information, and server logs collected automatically when you access the Service.
Cookie data: session identifiers and locale preference cookies necessary to operate the Service.
OAuth data (if enabled): if you sign in with a third-party provider such as Google or Facebook, we receive basic profile information as permitted by that provider.

3. How we use your data

We use your personal data for the following purposes:

To provide, maintain, and improve the Service, including account management and event coordination features.
To communicate with you about your account, security, and Service updates.
To display public listings and user-generated content you choose to publish.
To ensure security, prevent abuse, and comply with legal obligations.
To analyze aggregated, non-identifying usage patterns to improve the Service.

4. Legal bases for processing (EEA users)

If you are located in the European Economic Area, we process your personal data on the following legal bases:

Performance of a contract: to provide the Service you request when you create an account or use our features.
Legitimate interests: to secure the Service, prevent fraud, and improve functionality, where those interests are not overridden by your rights.
Consent: where required, for example for optional communications or non-essential cookies.
Legal obligation: where we must retain or disclose data to comply with applicable law.

5. Cookies

We use essential cookies to keep you signed in and to remember your language preference. These cookies are necessary for the Service to function and do not require consent under applicable law.

We do not use third-party advertising or analytics cookies unless explicitly stated otherwise in an updated version of this policy.

6. Sharing and processors

We do not sell your personal data. We may share data with:

Hosting and infrastructure providers that process data on our behalf under contractual safeguards.
OAuth authentication providers when you choose to sign in through them.
Authorities or third parties when required by law or to protect rights, safety, and security.

7. Data retention

We retain your personal data for as long as your account is active or as needed to provide the Service. You may request deletion of your account and associated data, subject to legal retention requirements.

Server logs and security records may be kept for a limited period for troubleshooting and abuse prevention.

8. Your rights

Depending on your location, you may have the right to access, rectify, erase, restrict, or object to processing of your personal data, and to data portability.

You may withdraw consent at any time where processing is based on consent, without affecting the lawfulness of prior processing.

If you are in the EEA, you may lodge a complaint with your local data protection supervisory authority.

To exercise your rights, contact us at support@nerdik.app. We will respond within the timeframes required by applicable law.

9. Security

We implement appropriate technical and organizational measures to protect your personal data. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.

10. Children

The Service is not directed at children under 16. We do not knowingly collect personal data from children. If you believe a child has provided us with personal data, contact us at support@nerdik.app.

11. International transfers

Your data may be processed in countries other than your own. Where required, we ensure appropriate safeguards are in place for such transfers.

12. Changes to this policy

We may update this Privacy Policy from time to time. We will post the revised version on this page and update the "Last updated" date. Continued use of the Service after changes constitutes acceptance of the updated policy.
