ZIMEM TERMS OF USE AND END USER LICENCE AGREEMENT Version 1.0 — Effective 18 Ağustos 2026

5.1 Parties and acceptance

This agreement is between Serdar Güven ("Developer") and the person who downloads and uses the Zimem application ("User"). By downloading, installing or using the App you accept these terms. If you do not accept them, do not use the App and remove it from your device.

This agreement replaces Apple's Standard End User Licence Agreement. Where it conflicts with the Apple Media Services Terms, Apple's terms govern the purchase and distribution relationship.

5.2 What the App is

Zimem applies a fixed, sourced set of established Islamic jurisprudential rules to a personal timeline you declare yourself, in order to estimate a range for your accumulated missed obligatory prayers and fasts, and to divide that total into a daily tracking routine.

The App is deterministic: identical declarations always produce identical results. It contains no artificial intelligence, no language model and no generative component of any kind.

5.3 The App does not issue religious rulings — this is a material term

The User acknowledges and accepts that:

(a) The App's output is not a fatwa, religious ruling, or binding opinion. The Developer is not a religious authority, mufti's office, fatwa council or religious service provider and does not act as one.

(b) The App exercises no independent juristic reasoning (ijtihad). It applies a limited set of established rules — each shown with its source in the in-app "Jurisprudential Choices and Sources" screen — to the dates and durations you declare, and performs arithmetic.

(c) The result is only as accurate as your declaration. Incorrect, incomplete or estimated input produces an incorrect result. The App does not and cannot verify what you declare.

(d) The result is presented as a range, not an exact figure. That range is derived from the genuine uncertainty in your own declaration and is an estimate. Your actual obligation may fall inside or outside it.

(e) Marking an item complete in the App does not mean the obligation has been validly discharged in religious terms. It updates your own record and nothing more.

(f) For a binding religious ruling, consult a competent authority — the relevant office of the Presidency of Religious Affairs, your local mufti's office, or a qualified scholar you trust. The App is not a substitute for, and is not an alternative to, that consultation.

(g) Contested matters are out of scope. The distinction between istihada and menstruation, mutahayyira cases, fidya, isqat, dawr, rulings specific to persons who embraced Islam later in life, and proportional treatment of periods of partial observance are all outside the App's scope. The App produces no result on these and must not be read as doing so.

(h) The choice of madhhab is yours. The App does not prefer, recommend or endorse one school over another; it applies the rules of the school you select.

5.4 No medical claims

Menstruation, childbirth, postpartum and illness information entered into the App is date and duration data only, used solely to compute jurisprudential deductions. The App is not a medical device or health application. It provides no diagnosis, no treatment advice, no cycle or pregnancy prediction, no fertility information and no medical advice of any kind. Consult a physician for anything concerning your health.

5.5 Prayer times

The App computes prayer times on your device for the city you select manually, using an open-source astronomical library. Depending on the calculation parameters selected, these may differ by several minutes from official timetables. The authoritative source is the timetable published by the Presidency of Religious Affairs or the competent authority in your country. Times shown in the App are informational and do not replace those timetables. The App is not affiliated with, endorsed by or approved by any government or religious institution.

5.6 Notifications

All notifications are scheduled locally on your device. Operating-system power management, Focus modes, a powered-off device, time-zone changes or revoked notification permission may delay a notification or prevent it entirely. The Developer does not warrant delivery of any notification at any particular time. Observing prayer times remains the User's own responsibility.

5.7 Licence

The Developer grants the User a non-exclusive, non-transferable, non-sublicensable, revocable licence to use the App on Apple-branded devices that the User owns or controls, for personal, non-commercial purposes, as permitted by the Apple Media Services Terms. Ownership is not transferred; only a right of use is granted.

The User may not copy, rent, lease, sell or distribute the App; may not decompile, reverse engineer or create derivative works (save where mandatory law permits interoperability); may not present the App's output as the opinion of a religious authority; and may not reuse the App's jurisprudential texts in another product without written permission.

5.8 Intellectual property

The App's code, interface design, name, logo and all jurisprudential explanatory texts within it belong to the Developer. Those texts are original writing, not copied from any catechism or copyrighted work, and each is displayed with its source. The App contains no Qur'anic text, translation, exegesis, hadith text or recitation audio.

The App uses no third-party libraries; all code, including the prayer time calculation, belongs to the Developer. There is therefore no third-party open-source licence text in the App.

5.9 Purchases, permanently free functionality, and refunds

(a) Free core commitment. The accuracy of the derivation — including menstruation, postpartum, travel and incapacity deductions — is free and will not be placed behind a paywall. Payment covers forward-looking planning and convenience tools only. The Developer commits not to move currently free calculation functionality behind payment at a later date.

(b) Payment model. The in-app purchase is a one-time, non-subscription unlock. There is no auto-renewal, no recurring charge and no silent renewal.

(c) Apple is the merchant. The purchase relationship is between you and Apple. Price, tax and currency are set and displayed by Apple.

(d) Refunds are requested from Apple via "Report a Problem" and governed by Apple's refund policy; the Developer cannot issue refunds directly. A direct link to Apple's refund page is provided in the App's Settings screen.

(e) Right of withdrawal. Where digital content is supplied immediately upon purchase, statutory withdrawal exceptions may apply. This does not limit the rights Apple's own refund policy gives you. Mandatory consumer rights in your country of residence are unaffected.

(f) Pre-purchase disclosure. The purchase screen displays the price, that the purchase is one-time, exactly what is unlocked, a "Restore Purchases" control, and links to this agreement and the Privacy Policy.

5.10 Disclaimer of warranties

The App is provided "as is" and "as available". To the maximum extent permitted by law, the Developer makes no express or implied warranty that the App will operate uninterrupted or error-free, that calculations will be correct in every case, that it will meet your expectations, or that it is fit for a particular purpose.

Software defects are a real possibility. If you find a calculation error, report it to guvenser09@gmail.com; defects affecting the calculation engine are prioritised, and where a fix changes results, that change is announced clearly in-app.

5.11 Limitation of liability

To the maximum extent permitted by law, the Developer is not liable for indirect, incidental, special or consequential damages, loss of data, loss of profit, or the consequences of decisions taken in reliance on the App's output. The Developer's total aggregate liability is limited to the amount you actually paid for the App in the preceding twelve months.

Carve-outs: this limitation does not apply to liability arising from the Developer's wilful misconduct or gross negligence, to death or personal injury, or to any liability that cannot be excluded under mandatory consumer protection law.

5.12 Age

An in-app purchase requires the User to be at least eighteen years old or to have the consent of a parent or guardian. No age limit applies to the App's free functionality, but the App is not designed for children.

5.13 Apple-specific provisions

The User acknowledges that: this agreement is between the User and the Developer, not Apple; the Developer alone is responsible for the App and its content; Apple has no obligation to furnish any maintenance or support; in the event of any failure of the App to conform to any applicable warranty, the User may notify Apple and Apple may refund the purchase price, and to the maximum extent permitted by law Apple has no other warranty obligation whatsoever, with all other claims directed to the Developer; the Developer, not Apple, is responsible for product liability claims, claims of non-conformity with legal requirements, and claims under consumer protection law; the Developer, not Apple, is responsible for investigating, defending, settling and discharging any third-party intellectual property infringement claim relating to the App; the User represents that they are not located in a country subject to a U.S. Government embargo and are not on any U.S. Government prohibited-party list; and Apple and its subsidiaries are third-party beneficiaries of this agreement and, upon the User's acceptance, will have the right to enforce it against the User.

5.14 Changes

These terms may change. Material changes are announced in-app, and earlier versions stay published on this site. Continued use after a change constitutes acceptance. If you do not accept, you may remove the App.

5.15 Governing law

This agreement is governed by the laws of the Republic of Türkiye, with the courts at the Developer's place of residence having jurisdiction. Consumers may bring proceedings before the consumer arbitration committee or consumer court at their own place of residence. Mandatory consumer protection rules of a consumer's country of residence remain unaffected.
