Discount Calculator Terms of Service
Last updated 6 September 2026
These Terms of Service (the “Terms”) form a binding legal agreement between you and Alper Kaplan (“we”, “us” or “our”), the developer and provider of the Discount Calculator application (“Discount Calculator” or the “App”). By downloading, installing or using the App, you confirm that you have read, understood and agree to be bound by these Terms and by our Privacy Policy. If you do not agree, do not download, install or use the App. Sections 12 (Disclaimer of Warranties), 13 (Limitation of Liability) and 14 (Indemnification) limit our liability and allocate risk to you, so please read them carefully.
1. Definitions
1.1 “App” or “Discount Calculator” means the Discount Calculator application, together with its updates, content and documentation.
1.2 “We”, “us” and “our” mean Alper Kaplan.
1.3 “You” and “your” mean the individual or entity using the App.
1.4 “Apple” means Apple Inc. and its subsidiaries.
1.5 “Device” means the iPhone or iPad on which you install and run the App.
1.6 “Content” means the prices, discounts, sales tax rates, item names, notes and links you enter in the App, together with the calculations, comparisons and worksheets you save and any PDF the App produces from them.
2. Eligibility and acceptance
You may use the App only if you can form a binding contract with us and are not barred from doing so under applicable law. If you are under the age of majority in your place of residence, you may use the App only with the involvement and consent of a parent or legal guardian. By using the App you represent that you meet these requirements and that you will comply with the Apple Media Services Terms and Conditions.
3. Licence
Subject to your compliance with these Terms, we grant you a personal, limited, non-exclusive, non-transferable, non-sublicensable and revocable licence to install and use the App for your own purposes on an Apple-branded device (iPhone or iPad) that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions and Apple’s standard Licensed Application End User License Agreement (the “Standard EULA”).
4. Licence restrictions
Except to the extent applicable law prohibits these restrictions, you will not, and will not permit anyone else to:
4.1 copy, modify, adapt, translate or create derivative works of the App;
4.2 reverse engineer, decompile, disassemble or attempt to derive the source code of the App;
4.3 rent, lease, lend, sell, sublicense, distribute or otherwise transfer the App;
4.4 remove, obscure or alter any proprietary notices in the App;
4.5 use the App for any unlawful, infringing or harmful purpose, or in violation of these Terms; or
4.6 interfere with or disrupt the integrity or performance of the App.
5. Price and purchases
The App is a paid app. You buy it once from the App Store, and the price is shown to you before you buy. There is no subscription, and the App contains no in-app purchases. Apple sells and processes the purchase, handles your payment and any applicable taxes, and we do not receive or store your payment details. Refunds are handled by Apple under the Apple Media Services Terms and Conditions, not by us. If paid features are ever added, they will be sold and processed by Apple through the App Store, and the applicable price and terms will be shown to you before any purchase.
6. Your Content, accuracy and responsibility
As between you and us, you retain all rights in your Content, and you are solely responsible for it and for the accuracy of everything you enter. THE APP IS A CALCULATION AID. EVERY FIGURE IT SHOWS DEPENDS ENTIRELY ON THE PRICES, DISCOUNTS AND SALES TAX RATES YOU ENTER AND ON THE ORDER YOU ENTER THEM IN. IT IS NOT FINANCIAL, TAX, ACCOUNTING OR LEGAL ADVICE, IT DOES NOT DETERMINE THE TAX ACTUALLY DUE IN YOUR JURISDICTION, AND IT IS NOT A SUBSTITUTE FOR THE PRICE A SELLER ACTUALLY CHARGES. ALWAYS CHECK THE FINAL PRICE AT THE POINT OF SALE BEFORE RELYING ON IT.
THE APP IS NOT A BACKUP, ARCHIVING OR STORAGE SERVICE. YOUR SAVED CALCULATIONS, COMPARISONS AND WORKSHEETS ARE HELD ONLY ON YOUR DEVICE, THEY ARE NOT SYNCHRONISED TO ANY SERVICE WE OPERATE, AND DELETING THE APP DELETES THEM. YOU ARE RESPONSIBLE FOR KEEPING YOUR OWN RECORD OF ANYTHING THAT IS IMPORTANT TO YOU. We are not responsible for any loss, corruption or unavailability of your Content, or for any decision you make on the basis of a figure the App displays.
7. Acceptable use
You agree to use the App lawfully and responsibly. You will not use the App:
7.1 in violation of any applicable law or regulation;
7.2 to infringe the intellectual-property, privacy or other rights of any person;
7.3 to produce or distribute any document that misrepresents a price, a discount or a tax amount to another person; or
7.4 in any manner that could damage, disable or impair the App or interfere with any other party’s use of it.
8. Third-party services and sharing
The App is distributed through, and relies on, services operated by Apple. When you export a PDF, the App hands the file to Apple’s standard share sheet and you choose what happens to it; any app or service you send it to handles it under its own terms and privacy policy, and we play no part in that. We do not control and are not responsible for Apple’s services or any third-party software you use to open, store or send an exported file. The App itself contains no advertising, analytics or tracking, and makes no network connections of its own.
9. Intellectual property
The App, and all software, design, text, graphics, names, logos and other materials it contains (excluding your Content), are owned by us or our licensors and are protected by intellectual-property and other laws. Except for the licence expressly granted in these Terms, no rights are granted to you, and we reserve all rights.
10. Feedback
If you send us suggestions, ideas or other feedback about the App, you grant us a perpetual, irrevocable, worldwide, royalty-free licence to use and incorporate that feedback for any purpose, without any obligation or compensation to you.
11. Privacy
Your use of the App is also governed by our Privacy Policy, which is incorporated into these Terms by reference.
12. Disclaimer of warranties
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE APP IS PROVIDED “AS IS” AND “AS AVAILABLE”, WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. WE DISCLAIM ALL WARRANTIES, WHETHER EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, ACCURACY AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, TIMELY, SECURE, ERROR-FREE OR FREE OF DATA LOSS, THAT ANY FIGURE IT CALCULATES WILL MATCH THE AMOUNT A SELLER OR TAX AUTHORITY ACTUALLY CHARGES, OR THAT THE APP WILL MEET YOUR REQUIREMENTS. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU.
13. Limitation of liability
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL WE BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, DATA, GOODWILL OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR RELATING TO THE APP OR THESE TERMS, WHETHER BASED ON CONTRACT, TORT, NEGLIGENCE, STRICT LIABILITY OR ANY OTHER THEORY, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE APP OR THESE TERMS WILL NOT EXCEED THE GREATER OF THE AMOUNT YOU PAID FOR THE APP IN THE TWELVE MONTHS BEFORE THE EVENT GIVING RISE TO THE LIABILITY, OR TEN UNITED STATES DOLLARS (US$10). NOTHING IN THESE TERMS EXCLUDES OR LIMITS ANY LIABILITY THAT CANNOT BE EXCLUDED OR LIMITED UNDER APPLICABLE LAW, AND SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU.
14. Indemnification
To the maximum extent permitted by applicable law, you agree to indemnify, defend and hold harmless Alper Kaplan from and against any claims, liabilities, damages, losses and expenses (including reasonable legal fees) arising out of or relating to: (a) your use or misuse of the App; (b) your Content; (c) your violation of these Terms; or (d) your violation of any law or the rights of any third party.
15. Term and termination
These Terms apply while you use the App. You may terminate them at any time by ceasing to use and deleting the App. We may suspend or terminate your licence immediately if you breach these Terms. Sections that by their nature should survive termination, including Sections 6, 9, 10 and 12 to 20, will survive.
16. Changes to the App and these Terms
We may modify, suspend or discontinue the App, in whole or in part, at any time. We may also revise these Terms from time to time; the date at the top indicates when they were last revised, and material changes will be posted on this page. Your continued use of the App after changes take effect constitutes acceptance of the revised Terms.
17. Governing law and disputes
These Terms are governed by the laws applicable in the place where the developer is established, without regard to conflict-of-law principles, and subject to any mandatory rights you have as a consumer under the laws of your country of residence. Before bringing any formal claim, you agree to contact us through our support page and to attempt in good faith to resolve the matter informally. The courts of the developer’s place of establishment will have jurisdiction, except where applicable law entitles you to bring proceedings in your own country.
18. Apple App Store additional terms
The following terms apply because the App is licensed through the App Store:
18.1 These Terms are between you and us only, and not with Apple. Apple is not responsible for the App or its content.
18.2 The licence granted to you is limited to a non-transferable licence to use the App on any Apple-branded device (iPhone or iPad) that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions.
18.3 Apple has no obligation to furnish any maintenance or support services for the App.
18.4 To the maximum extent permitted by law, Apple has no warranty obligation with respect to the App. If the App fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price (if any); Apple has no other warranty obligation.
18.5 Apple is not responsible for addressing any claims by you or any third party relating to the App or your possession or use of it, including product-liability claims, claims that the App fails to conform to any legal or regulatory requirement, and claims arising under consumer-protection or similar legislation.
18.6 Apple is not responsible for the investigation, defence, settlement or discharge of any third-party claim that the App or your use of it infringes that third party’s intellectual-property rights.
18.7 You represent that you are not located in a country subject to a U.S. Government embargo or designated as “terrorist-supporting”, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
18.8 You must comply with applicable third-party terms of agreement when using the App.
18.9 Apple and its subsidiaries are third-party beneficiaries of these Terms and, upon your acceptance, will have the right to enforce these Terms against you.
19. General
19.1 Entire agreement. These Terms and the Privacy Policy are the entire agreement between you and us regarding the App and supersede any prior agreements.
19.2 Severability. If any provision is held unenforceable, it will be modified to the minimum extent necessary, and the remaining provisions will remain in effect.
19.3 No waiver. Our failure to enforce any provision is not a waiver of it.
19.4 Assignment. You may not assign these Terms without our consent; we may assign them in connection with a transfer of the App.
