Applies to every app published by Mert Çetin. Last updated 6 August 2026.
You get a personal, non-transferable licence to use these apps on Apple devices you own or control, under Apple's Licensed Application End User License Agreement, which applies in full. Where these terms and Apple's disagree, Apple's win.
Some apps offer auto-renewable subscriptions. The title, the length of each period, what it unlocks and the price are shown in the app before you confirm, and the price you pay is the one Apple displays for your region.
Payment is taken by your Apple Account at confirmation of purchase. A subscription renews automatically unless it is cancelled at least 24 hours before the current period ends, and the renewal is charged within 24 hours of the period ending. Manage or cancel in Settings → your name → Subscriptions. Any unused part of a free trial is forfeited when a subscription is purchased.
Some apps also offer a one-time (lifetime) purchase. It is charged once, does not renew, and is processed by Apple like a subscription. In Deprem Uyarı Sistemi: Anlık the first 7 days of notifications are free without a card; that trial is run by the app's server and is not a subscription.
Refunds are Apple's to give, at reportaproblem.apple.com.
Several of these apps read sensors or public data. They are informational tools, not instruments, and not professional, medical, safety or legal advice. Each app states its own limits on a screen reachable in a few taps; those statements are part of these terms. In particular, Deprem Uyarı Sistemi: Anlık is not an early warning system: it notifies you after an official source has published an earthquake, and it does not predict one. Do not rely on any of them where being wrong would be dangerous.
Do not use the apps to break the law or to interfere with anyone else's privacy or property. Do not decompile or resell them.
The apps are provided as they are, without warranty, to the extent the law allows. Nothing here limits liability that cannot lawfully be limited.
