The terms, in brief.

These terms govern your use of the Davul iOS app, its widgets and the Davul pages on metehanbicer.com, provided by Metehan Biçer, an independent developer based in Türkiye (“the developer”). Because you get the app from the App Store, Apple’s Licensed Application End User License Agreement (EULA) also applies. These terms add to the EULA; where they conflict, the EULA prevails.

I grant you a non-transferable, non-exclusive licence to use Davul on Apple devices you own or control, for personal, non-commercial purposes, within the App Store Usage Rules. Copying, modifying, reverse engineering or redistributing the app is not allowed, except where the law expressly permits it. The app’s design, icons, images and interface texts belong to the developer.

Davul is free. There are no ads, subscriptions or in-app purchases. Nothing is bought or paid for through Davul.

Duas are shown with their hadith sources (Abu Dawud, Tirmidhi). The verses on fasting (Al-Baqara 183-186) are given in Arabic with the Pickthall translation. The dates of Ramadan 1448 follow the Diyanet calendar: it begins on 8 February 2027 and lasts 29 days. I take care to reproduce the texts faithfully; if you find an error, write to me and I will fix it. For questions about fasting and worship, ask a scholar or an institution you trust.

Times are calculated on your phone with the Diyanet (Turkey) method, using the open-source adhan library. Official timetables are prepared with details such as district and altitude, so a difference of a minute or two is possible. Whether reminders arrive on time also depends on your phone’s settings and on iOS. Leave a margin at suhoor, and if you are ever unsure, follow the official timetable where you are.

Davul has no accounts and no server; your city, your settings and your fast tracker are kept only on your phone. If you delete the app or reset your phone, they are deleted too. Details are in the privacy policy.

Davul is provided “as is” and “as available”. I cannot guarantee that the app will run without interruption or errors, that the times will match every official timetable exactly, or that reminders will always arrive. I may change the app or withdraw it. Rights the law grants you that cannot be limited are not affected.

To the extent the law allows, the developer is not liable for indirect damages or data loss arising from using or being unable to use Davul, from differences in the calculated times, or from reminders that did not arrive. This does not affect liability for intent or gross negligence, or your rights under consumer protection law.

I may update these terms. I will publish changes on this page and update the effective date. If a change is significant, I will also point it out in the app or on this site. Continuing to use Davul after a change means you accept the updated terms.

These terms are governed by the laws of the Republic of Türkiye. Turkish courts and enforcement offices have jurisdiction over disputes; consumers may also apply to consumer arbitration committees and consumer courts within the legal limits. Mandatory consumer protection rules of the country where you live are not affected.
