Terms of use
Last updated 5 November 2026
These terms cover the Geostay website at getgeostay.com. They are an agreement between you and Mehmet Ali Kısacık, an individual based in Istanbul, Turkey, who makes Geostay. The iPhone app is licensed separately under Apple's standard licensed application end user license agreement.
The app
Geostay is an iPhone app that records the days you spend in each country and counts them against visa, residence and tax rules. Use of the app is governed by Apple's standard EULA.
If these website terms and the Apple EULA both speak to the same point about the app, the Apple EULA governs the app.
The website
The pages on this site describe Geostay. You may read them for your own information. You may not copy them onto another site, scrape them in bulk, or present them as your own product.
Your records
The travel history you keep in the app stays on your iPhone. We do not receive that history, so we claim no rights over it. You are responsible for the files you import and for the reports you choose to share.
Information, not advice
Geostay gives information about day counts. It is not legal, immigration or tax advice, and it does not decide your status. When a lot depends on a result, check it with an immigration lawyer or a tax adviser.
Purchases
Payments are processed by Apple. We never see your name, Apple Account, card or billing details. You manage or cancel a subscription in your Apple Account settings. Refunds are handled by Apple under App Store policies.
Acceptable use
Don't attempt to reverse engineer, resell, or tamper with the app, and don't use the app or this website to break the law.
Disclaimer and limitation of liability
The website and the descriptions on it are provided "as is", to the extent permitted by law. To the maximum extent permitted by law, Mehmet Ali Kısacık is not liable for indirect or consequential damages arising from your use of the website. Nothing in these terms excludes liability that cannot be excluded by law.
- Day counts in the app are information for you to read. They are not a determination of your visa, residence or tax status.
Governing law
These website terms are governed by the laws of Turkey, and disputes are subject to the courts of Istanbul, Turkey, unless the consumer protection rules of your country of residence provide otherwise.
Changes to these terms
If we change these terms in a meaningful way, we will update the date at the top of this page. Continued use of the website after a change means the updated terms apply.
