Privacy Policy

This Privacy Policy explains how the 30 Seconds mobile app handles information.

Effective date: 13 May 2026 · Last updated: 13 May 2026

1. Who we are

The 30 Seconds app ("the App") is developed and published by Joost Muijsenberg ("we", "us", "our"), based in the Netherlands. We act as the data controller for any personal data processed through the App.

For any privacy-related questions or requests, contact us at joostmuijsenberg.dev@gmail.com.

2. Summary

• We do not require an account, and we do not collect your name, email address or contact details.
• The App displays advertisements through Google AdMob. AdMob may collect device and usage information to serve ads.
• We do not knowingly collect data from children under 13.
• You can opt out of personalised ads in your device settings at any time.

3. Information we collect

3.1 Information you provide

The App does not require registration. We do not ask for personal information directly. If you contact us by email, we will process the information you choose to send us in order to respond.

3.2 Information collected automatically

The App itself does not collect analytics or telemetry. However, third-party services used in the App may automatically collect limited information, as described below.

4. Advertising

The App uses Google AdMob to display advertisements. AdMob is provided by Google Ireland Limited and may collect and process the following information:

• Advertising identifier (such as the Android Advertising ID or Apple's IDFA)
• Device information (model, operating system, language, region)
• Approximate location derived from IP address
• Information about ad interactions (impressions, clicks)

This information is used by Google to deliver, measure and (where permitted) personalise advertisements, and to prevent fraud and abuse. Google acts as an independent data controller for this processing.

For more information, see Google's privacy policy: https://policies.google.com/privacy and how Google uses information from sites or apps that use their services: https://policies.google.com/technologies/partner-sites.

4.1 Consent and personalised ads (EU/EEA, UK, Switzerland)

If you are located in the EU/EEA, the UK or Switzerland, the App will ask for your consent before personalised ads are shown, using Google's User Messaging Platform (UMP) consent dialog. You can withdraw or change your consent at any time from within the App or by resetting your advertising identifier in your device settings.

If you do not consent, the App will continue to show non-personalised advertisements.

4.2 Opting out of personalised advertising

• Android: Settings → Google → Ads → "Delete advertising ID" / "Opt out of Ads Personalization".
• iOS: Settings → Privacy & Security → Tracking → disable "Allow Apps to Request to Track". You can also disable personalised ads in Settings → Privacy & Security → Apple Advertising.

5. Legal basis for processing (GDPR)

If you are in the European Economic Area, we rely on the following legal bases under the General Data Protection Regulation (GDPR):

• Consent (Art. 6(1)(a) GDPR) for personalised advertising and any optional tracking.
• Legitimate interests (Art. 6(1)(f) GDPR) for non-personalised advertising, fraud prevention and ensuring the App functions correctly.

6. Sharing of information

We do not sell your personal information. The only parties that may receive information generated by your use of the App are the advertising service providers listed above. We do not share data with any other third parties unless required by law.

7. International transfers

The advertising provider mentioned above is established in the EU but may transfer data to servers located outside the European Economic Area, including the United States. Such transfers are protected by appropriate safeguards (such as the EU-U.S. Data Privacy Framework and Standard Contractual Clauses) as described in Google's privacy policy.

8. Data retention

We do not store any personal data on our own servers. Retention of any data processed by the advertising provider is governed by their own retention policies, available in their privacy policy.

9. Your rights

Depending on where you live, you may have the right to:

• access the personal data we hold about you
• request correction or deletion
• object to or restrict processing
• withdraw consent at any time
• lodge a complaint with a supervisory authority (in the Netherlands: the Autoriteit Persoonsgegevens, autoriteitpersoonsgegevens.nl)

Because we do not collect personal data directly, requests regarding ad-related data should generally be addressed to the advertising provider. You can still contact us at joostmuijsenberg.dev@gmail.com for assistance.

10. Children's privacy

The App is not directed at children under 13 and we do not knowingly collect personal data from children under 13. If you believe a child has provided us with personal information, please contact us so we can take appropriate action.

11. Security

We take reasonable technical and organisational measures to protect any information we process. However, no method of transmission over the internet or method of electronic storage is fully secure.

12. Changes to this policy

We may update this Privacy Policy from time to time. The "Last updated" date at the top of this page reflects the most recent revision. Material changes will be communicated via the App or this page.
