Zelzele Download

Zelzele terms of use

Last updated: 20 August 2026

These Terms of Use (the "Terms") govern the use of the Zelzele iOS application (the "App") provided by Enmera Yazılım Eğitim Reklam Danışmanlık Ticaret Limited Şirketi ("Enmera"). By downloading or using the App, you are deemed to have accepted these Terms.

1. Scope of the Service

Zelzele lists earthquake data compiled from public sources such as AFAD, the Kandilli Observatory (KOERI), EMSC and USGS, displays it on a map, sends notifications according to criteria you choose, presents statistics and generates informational AI-assisted analyses. The App is free and contains advertising.

2. Important Notice: Zelzele Is Not an Official Early Warning System

This clause is the most critical provision regarding use of the App:

  • The App reports data published after earthquakes have occurred. It does not provide pre-earthquake warnings or predictions.
  • Zelzele is not an official disaster warning system; it has no official affiliation with AFAD or any other public authority and is not a substitute for them.
  • Data is obtained from third-party sources. Delays, outages, errors or subsequent revisions in those sources (for example an updated magnitude value) are reflected in the App. Enmera does not guarantee the accuracy, completeness, timeliness or uninterrupted delivery of the data.
  • Delivery of notifications depends on your internet connection, device settings, the operating system and notification infrastructure. Delivery of a notification cannot be guaranteed.
  • In an emergency, always follow the instructions of AFAD and other official sources. Do not base decisions concerning your safety or property on this App alone.

3. AI Analyses

The AI analyses in the App are for general information only; they do not constitute scientific opinion, engineering assessment or official statement. AI-generated text may be inaccurate or incomplete. Do not make structural, financial or safety-related decisions based on this content.

4. Account

You can sign in with your Google or Apple account, or continue as a guest. You are responsible for the security of your account and for activity carried out through it. To request deletion of your account, write to info@enmera.com.tr.

5. User Content and Community Rules

You can vote on an earthquake ("I felt it / I didn't feel it") and post comments. This content is publicly visible to other users together with your name. The following are prohibited:

  • Sharing baseless earthquake predictions, or information that is misleading or likely to cause panic,
  • Using insulting, hateful, harassing or discriminatory language,
  • Sharing content that violates the personal data or rights of third parties,
  • Posting advertising, spam or irrelevant content.

Enmera reserves the right to remove content that violates these rules without prior notice and to restrict the relevant account's access. You alone are responsible for the content you share.

6. Rules of Use

You may not use the App in violation of applicable law, to infringe the rights of third parties, or to harm the operation of the App. You may not reverse engineer the App, attempt to access its source code, or scrape its data in bulk using automated tools.

7. Intellectual Property

The App, its design, logo and all its components belong to Enmera and are protected by applicable law. You are granted only a non-exclusive, non-transferable licence for personal use. Copyright in the earthquake data remains subject to the relevant source institution.

8. Advertising

Third-party advertising (Google AdMob) is displayed in the App. The relevant advertiser is responsible for ad content. Personalisation of ads depends on your choice regarding Apple's App Tracking Transparency (ATT) permission; details are explained in the Privacy Policy.

9. Limitation of Liability

The App is provided "as is". Enmera does not warrant uninterrupted or error-free operation and, to the maximum extent permitted by law, cannot be held liable for any direct or indirect damages arising from the use of, or inability to use, the App or the data it contains. This limitation also covers cases where notifications are not delivered or are delivered late.

10. Changes and Termination

Enmera may update the App and these Terms; significant changes will be published on this page. Your access may be restricted in the event of a breach of these Terms.

11. Governing Law

These Terms are governed by the laws of the Republic of Türkiye; the courts and enforcement offices of Istanbul have jurisdiction over any disputes.
