Zelzele privacy policy
Last updated: 20 August 2026
This Privacy Policy explains what data is processed when you use the Zelzele iOS application (the "App"), developed by Enmera Yazılım Eğitim Reklam Danışmanlık Ticaret Limited Şirketi ("Enmera", "we").
1. Account and Identity Information
You can sign in to Zelzele with your Google or Apple account, or continue as a guest. Guest sign-in does not collect any information that can be linked to your identity.
- Sign in with Google: Your first name, last name and email address are collected.
- Sign in with Apple: You may use Apple's "Hide My Email" option, in which case we cannot access your real email address.
- Guest sign-in: Only an anonymous device identifier is created.
This information is stored on Google Firebase Authentication and Firestore, and is used to sync your notification preferences across your devices. We do not sell your data and we do not share it with third parties for advertising purposes.
2. Location Data
If you grant location permission, your location is used on your device only: to sort earthquakes closest to you, to detect your country automatically on first launch, and to show your position on the map. Your location data is never sent to our servers and is not stored. If you decline, the App continues to work with all its features; only the "earthquakes near me" ordering is disabled.
3. Notifications
Earthquake notifications are delivered through Firebase Cloud Messaging (FCM). For this purpose we store a notification token belonging to your device along with your notification preferences (magnitude threshold, city, data source). You can turn notifications off at any time from within the App or from iOS Settings.
4. Social Interactions (Publicly Visible)
When you vote on an earthquake ("I felt it / I didn't feel it") or post a comment, your name and your content are publicly visible to other users. This content is stored in Firestore. Please do not include personal information you would not want to share in your comments. If you would like your comments removed, contact us at the address below.
5. AI Analysis
The AI analysis on an earthquake's detail screen is generated from earthquake data (magnitude, location, depth, time) sent to the Google Gemini service through our servers. These requests contain no personal data of yours; only publicly available earthquake information is transmitted.
6. Source of Earthquake Data
Earthquake data in the App is obtained from public sources such as AFAD, the Kandilli Observatory (KOERI), EMSC and USGS. This is public data and contains no personal information. Enmera does not guarantee its accuracy, completeness or timeliness.
7. Automatically Collected Data and Advertising
To improve the App, fix errors and display advertising, we work with the following service providers:
- Google Firebase Analytics: Anonymous usage statistics (product interaction data such as screen views and feature usage). Details: Google Privacy Policy.
- Google AdMob: Device identifiers and ad interaction data for the banner and interstitial ads shown in the App. Details: Google Privacy Policy.
- Meta (Facebook) App Events: A limited set of events — app launch, completed registration, notification permission granted and content view — is sent to Meta to measure the performance of our app advertising. No personal information such as your name, email or location is attached to these events. Details: Meta Privacy Policy.
- Apple SKAdNetwork: Ad attribution is performed through Apple's privacy-preserving measurement infrastructure, which contains no personal data.
8. App Tracking Transparency (ATT) and the Advertising Identifier
The App requests Apple's App Tracking Transparency (ATT) permission. Your decision determines access to your advertising identifier (IDFA):
- If you allow: Your advertising identifier is shared with AdMob and Meta to measure ad performance and personalise ads to your interests.
- If you do not allow: Your advertising identifier is not accessed, ads are not personalised, and measurement is performed solely through Apple's anonymous SKAdNetwork infrastructure.
In both cases Zelzele continues to work with all its features. You can change your decision at any time under iOS Settings > Privacy & Security > Tracking.
9. Permissions
- Notifications: To deliver earthquake alerts.
- Location: To sort earthquakes near you and show your position on the map.
- Photos (add only): To save images containing earthquake information to your gallery.
- Tracking (ATT): For ad measurement and personalisation.
You can change permissions at any time from iOS Settings.
10. Data Retention and Account Deletion
Your account data is retained for as long as your account is active. To request deletion of your account and its associated data, write to info@enmera.com.tr; your request will be fulfilled within 30 days. Signing out of the App does not delete your account.
11. Children's Privacy
The App is not directed at children under 13 and we do not knowingly collect data from children.
12. Your Rights
Under Turkish Law No. 6698 on the Protection of Personal Data (KVKK) and other applicable data protection legislation (including the GDPR), you have the right to access, correct and delete your data and to object to its processing. For your requests, contact us at info@enmera.com.tr.
13. Changes
Any changes to this policy will be published on this page. For significant changes, a notice may be shown within the App.
