Terms of Use
Effective date: 13 November 2026
Last updated: 13 November 2026
These terms are between you and Oğuz Mete YELTEN (“we”) and cover the Halal Phone app (called Helal Phone in Turkish) and this site. Halal Phone is offered not by a company but by an individual living in Türkiye. By using the app or the site you accept these terms.
Halal Phone will launch on Android first. The iPhone version has not been released; what is written below for iPhone and the App Store applies once that version is released.
How personal data is processed is explained in a separate document, the Privacy Policy and Privacy Notice. These terms are published in Turkish and English; if they differ, the Turkish text prevails.
Summary
- Halal Phone is a commitment tool you use by your own choice: before you open the apps you choose, it asks you to read a verse, and it locks them at prayer time. You can always lift the lock.
- Reading, translation, locks, the prayer lock, the emergency exit and never-locked apps are free. Premium currently unlocks detailed statistics.
- The store (Google Play; the App Store on iPhone) handles payment, renewal and cancellation. You can cancel a subscription at any time; deleting the app does not cancel it.
- Because Premium unlocks instantly, the 14-day right of withdrawal does not apply to this purchase in Türkiye; rights under the law of your country remain.
- Prayer times are calculated and may differ by a few minutes. The app does not issue fatwas or religious rulings.
- Your statutory rights as a consumer are not limited by these terms.
1. Parties and contact
- Provided by: Oğuz Mete YELTEN
- Address: Büyükçekmece, İstanbul
- Email: support@halalphone.app
- Distribution and payment: Google Play (Google) and, once the iPhone version is released, the App Store (Apple). Purchases are made in the store’s own screen and on its own terms; the store also applies its own terms of service.
The current text of these terms is always at this address; you can save or print it. The store emails you the receipt for a purchase.
2. What the app does and does not do
Halal Phone asks you to read a verse before opening the apps you choose; it gives you usage time in proportion to your reading. If you turn on the prayer lock, it locks the apps you choose when a prayer time begins and opens them when you tap “Prayed”.
It is a tool you use on your own phone, by your own decision. It is not a parental control, a tool for monitoring someone else, or anti-theft protection. The app is for ages 13 and up.
No one gets locked in
- The emergency exit is always there and pauses all locks for 1 hour with one tap.
- The prayer lock lasts at most 60 minutes and ends before the next prayer. “I can’t pray right now” postpones the lock immediately.
- Phone, messages and maps apps (as well as WhatsApp and WhatsApp Business) are protected from being locked. On iPhone, because Apple does not show us apps by name, a protected app may show a “this app is never locked” screen at most once; it opens with one tap. On iPhone, apps you add to Locks › Never locked are never locked.
- Turning the lock off permanently requires a 60-second wait and confirmation. You can end the lock at any time by removing the permission in your phone’s settings (Accessibility on Android, Screen Time on iPhone) or by deleting the app.
Do not rely on the app in an emergency; your phone’s emergency call feature is independent of this app’s lock.
3. Limits of the lock
The lock works through the system tools your phone provides: the accessibility service on Android, Apple’s Screen Time framework on iPhone. Their limits and errors are outside our control. We do not guarantee that the lock will always engage exactly on time on every phone. For example:
- On Android, battery saving, manufacturer app-killing features or “Force stop” can stop the lock. The app tells you as soon as it can notice; after “Force stop”, only when you open the app again.
- On iPhone, if the app is not opened for 30 days, prayer times run out and the prayer lock stops; the app warns you 3 days ahead.
- Changing the clock manually can shift the prayer lock.
- The app is a commitment tool; a determined user can always get around it. This is a deliberate choice.
4. Prayer times
Times are calculated on the phone with astronomical formulas, for the location you set. The default method depends on the region: a calculation close to the Diyanet method in Türkiye, the North American (ISNA) method in the US and Canada, Kemenag in Indonesia, UOIF in France, and the Muslim World League elsewhere. You can choose the standard or Hanafi calculation for Asr and change the method yourself.
Calculated times may differ by a few minutes from official timetables (e.g. Diyanet’s). The location is rounded to about 1 km. Near the polar regions, times are found with an approximate rule or cannot be calculated at all. For your worship, follow the official timetable or the mosque where you are.
5. Religious content
- Arabic text: from the Tanzil Project, shown unchanged (Creative Commons Attribution 3.0, source: tanzil.net).
- English translation: Marmaduke Pickthall’s translation, from a public-domain digital text. Because the printed edition it is based on has not been verified, it is marked “provisional” in the app.
- Turkish and other translations: not available yet; they will be added when a licensed source is available. Translations are not produced by machine translation or AI.
A translation is an attempt to convey the meaning of a verse; it does not replace the Qur’an. No religious text in the app was generated or altered by AI.
The app does not issue fatwas or religious rulings. “Prayed”, “I can’t pray right now” and “Lift the lock for this prayer” only manage the lock; they are not a religious assessment. The numbers and the streak are for you alone; an unmarked prayer does not mean it was not prayed. For religious questions, consult a scholar you trust or an official religious body.
7. Right of withdrawal and refunds
Right of withdrawal
Premium unlocks as soon as you confirm payment and is performed instantly online. For this reason, for consumers in Türkiye the 14-day right of withdrawal under Article 48 of Consumer Protection Law No. 6502 does not apply to monthly, yearly or lifetime purchases (Distance Contracts Regulation, Art. 15(1)(ğ)).
If you live in another country, your withdrawal rights under the law of that country remain. In the European Union and the United Kingdom, withdrawal and refunds are exercised through Google Play under the rules Google Play publishes for those countries (through Apple on iPhone).
Your right to cancel a subscription at any time, and in Türkiye to end it before the period ends and ask for a refund of the unused part, is separate from the right of withdrawal and always applies (see “Cancelling” above).
Refunds
- Android: request a refund from Google Play (play.google.com › Account › Order history). You can also write to us (support@halalphone.app); we will refund to the extent Google Play allows.
- iPhone: request a refund from Apple at reportaproblem.apple.com or through the link in your receipt. We cannot refund App Store purchases.
If Premium does not work or is not as described, your statutory rights for defective services and digital content (e.g. Law No. 6502, Arts. 11 and 15) remain, independently of the right of withdrawal. Write to us first; if we cannot fix the problem, we will direct you to the store for a refund or refund you through Google Play.
If a purchase is refunded, Premium turns off; your statistics are not deleted.
8. Licence and rules of use
We grant you a non-transferable, non-exclusive licence, free of charge for the free parts, to use the app on your own devices for personal, non-commercial purposes. The store’s usage rules also apply.
You must not: use the app unlawfully; reverse engineer, copy or distribute it except where the law allows; try to get around the app’s purchase checks; or alter religious texts and present them as the text of the app or its source.
9. Intellectual property and open source
The code, design and texts of the app and the site (except the third-party content below) belong to Oğuz Mete YELTEN. We do not claim that the names “Halal Phone” and “Helal Phone” or the logo are registered trademarks; even so, we ask you not to use these names or the logo in a way that could be confused with the app.
The app uses the following third-party content under its own licences: the Tanzil Arabic text (CC BY 3.0, the text may not be changed), the Pickthall translation (public domain), fonts (Amiri Quran, Atkinson Hyperlegible Next, Scheherazade New; SIL Open Font License 1.1), the Adhan prayer-time calculation (MIT) and the RevenueCat software (MIT). The licence texts are in the app under Sources and licences, and on the site on the Licences page.
10. This site and the waitlist
If you join the waitlist, we will send you one email when the app is released. This is not a promise of a release date or of any particular feature. The information on the site describes the app’s current plans and may change. Only people over 18 can join the list; details are in the Privacy Policy.
11. Warranty
We build the app and the site with care. To the extent the law allows, we provide the free parts “as is”: we do not guarantee that they will be uninterrupted, error-free or work the same on every phone. For paid Premium, we are responsible under the law for it working as described.
Halal Phone is not a medical or psychological treatment and does not replace treatment for addiction. If you need help with this, see a professional.
Your statutory rights as a consumer that cannot be excluded by contract remain.
12. Liability
To the extent the law allows, and only in cases of slight negligence, we are not liable for: the lock not engaging or engaging late, a message or notification missed in a locked app, calculated times differing from an official timetable, loss of data kept on the phone (e.g. when the app is deleted or when you move to a new phone with backup off), actions of the stores or phone manufacturers, and unforeseeable indirect damage.
These limits do not cover liability for intent and gross negligence (Turkish Code of Obligations No. 6098, Art. 115), liability for harm to life, body or health, statutory liability for defective services, or your statutory rights as a consumer that cannot be excluded by contract.
13. Termination and changes
You can stop using the app whenever you want. You need to cancel a subscription separately in the store.
We may change the app or the site, remove a feature or end the service. If we remove a paid feature or end the service, we will announce it in the app and on the site at least 30 days in advance. If we end the service, we will stop subscription renewals and refund the unused part of running subscriptions through Google Play. For a lifetime purchase, access is limited to the time the app is offered on that platform (above); your statutory rights remain.
If we change these terms, we will publish the new text here and announce important changes in the app or on the site. We will announce a change that affects you adversely at least 30 days before it takes effect; the previous terms continue to apply for a paid period that is running. If you do not accept the change, you can cancel your subscription and stop using the app.
If you seriously breach these terms (e.g. by getting around purchase checks), we may end this contract for you to the extent the law allows; we will tell you first.
14. If you downloaded from the App Store (once the iPhone version is released)
If you downloaded the app from Apple’s App Store, the following also applies:
- These terms are between you and us, not Apple. We, not Apple, are responsible for the app and its content.
- The licence is for use on Apple devices that you own or control, in line with the Usage Rules in the App Store Terms of Service.
- Apple has no obligation to provide maintenance or support for the app. For support, write to us: support@halalphone.app.
- If the app fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the price you paid for the app (if any). To the extent the law allows, Apple has no other warranty obligation with respect to the app.
- We, not Apple, are responsible for addressing claims relating to the app, such as product liability, failure to meet legal or regulatory requirements, and consumer protection or similar laws.
- We, not Apple, are responsible for investigating, defending and settling any claim that the app infringes someone’s intellectual property rights.
- You confirm that you are not located in a country subject to a US government embargo or designated as “terrorist supporting”, and that you are not on any US government list of prohibited or restricted parties.
- When using the app you must comply with applicable third-party terms (e.g. your internet service provider’s).
- Apple and its subsidiaries are third-party beneficiaries of these terms; once you accept them, Apple has the right to enforce these terms against you.
For matters not covered by these terms, Apple’s Licensed Application End User License Agreement applies; if the two conflict, whichever is more favourable to you as a consumer applies.
If you downloaded from Google Play, the Google Play Terms of Service also apply to purchases.
15. Governing law and disputes
These terms are governed by the law of the Republic of Türkiye. The courts and enforcement offices of Istanbul have jurisdiction over disputes; this jurisdiction rule does not, however, limit the consumer rights below.
If you are a consumer in Türkiye: for disputes below the monetary threshold, which is updated each year by the revaluation rate, you apply to the consumer arbitration committee where you live or where you made the transaction; for disputes above that threshold you can bring a case before the consumer court where you live (Law No. 6502, Arts. 68 and 73). Before bringing a case before a consumer court, mediation is mandatory (Art. 73/A).
If you are a consumer living in another country, the consumer protection rules of your country that cannot be excluded by contract, and your right to bring a case in that country, remain.
Let us first try to solve any problem by writing to us: support@halalphone.app.
If any provision of these terms is held invalid, the other provisions remain in force. These terms are published in Turkish and English; if they differ, the Turkish text prevails.
