Codexex
Terms of Service
Agreement
These Terms of Service ("Terms") govern your use of the Codexex application, including any updates, supplements, or supporting services (collectively, the "App"), provided by MAGRATHEAN UK LTD., a company registered in England and Wales (Company No. 16955343) with registered office at 16 Caledonian Court West Street, Watford, England, WD17 1RY. By downloading, installing, accessing, or using the App, you confirm that you have read, understood, and agree to be bound by these Terms and by any platform terms (including the Apple App Store EULA) applicable to the App. If you do not agree, do not download, install, or use the App.
License
MAGRATHEAN UK LTD. grants you a personal, limited, non-exclusive, non-transferable, non-sublicensable, revocable licence to install and use the App on Apple-branded devices that you own or control, in accordance with these Terms and the rules of any platform from which you obtained the App. The App is licensed, not sold; no title or ownership is transferred to you. All right, title, and interest in the App and its underlying intellectual property remain with MAGRATHEAN UK LTD. and its licensors. Any rights not expressly granted in these Terms are reserved.
Billing & Subscriptions
Codexex is provided free of charge. There are currently no subscriptions or in-app purchases. We reserve the right, on reasonable notice, to introduce paid features, subscriptions, or in-app purchases in future versions. Any such offering will be presented through the App Store and processed by Apple Inc. under Apple's payment terms.
Local Data, Connectivity, and Third-Party Account
Codexex connects directly from your device to OpenAI infrastructure (for sign-in and quota lookup) and to Apple platform services. You are solely responsible for: (a) maintaining a valid OpenAI account in good standing under OpenAI's terms; (b) the security of your OpenAI credentials; (c) any usage costs, quota, or rate limits imposed by OpenAI on your account; and (d) the accuracy and completeness of any quota, billing, or usage information shown by OpenAI. We do not host, replicate, or substitute for any OpenAI service; the App reads from OpenAI and is dependent on OpenAI's continuing availability and terms.
Eligibility
You must be at least 13 years old to use the App, or the minimum age required to consent to data processing in your jurisdiction, whichever is greater. By using the App, you represent and warrant that you meet this age requirement, that you have the legal capacity to enter into a binding agreement, and that you are not located in any country subject to a UK or US trade embargo or otherwise designated by the UK, US, EU, or UN as a prohibited or restricted destination, and that you are not on any UK, US, EU, or UN list of prohibited or restricted persons.
Apple App Store EULA
To the extent you obtained the App from the Apple App Store, you acknowledge and agree that these Terms are entered into between you and MAGRATHEAN UK LTD. only, and not with Apple Inc. ("Apple"). Apple is not a party to these Terms and is not responsible for the App or its content. Your use of the App is also governed by Apple's standard Licensed Application End User Licence Agreement (the "Apple EULA"), available at apple.com/legal/internet-services/itunes/dev/stdeula. In the event of any conflict between the Apple EULA and these Terms, the Apple EULA prevails with respect to the matters it expressly governs (including the scope of licence on Apple-branded devices, maintenance and support obligations, and the warranty refund mechanism limited to the purchase price paid through the App Store). Apple has no obligation to provide maintenance or support for the App. Apple is not responsible for addressing any user claim relating to the App, including product liability, consumer protection, regulatory, or intellectual-property claims. You acknowledge that Apple and its subsidiaries are third-party beneficiaries of these Terms and, upon your acceptance, will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.
Quota Information Is Provided As-Is
Quota readings, reset timing, history, session-burn analytics, weekly pace markers, and forecast values shown in the App are derived from third-party API responses (notably from OpenAI) and from local computation on your device. These values may be incomplete, delayed, inaccurate, rounded, cached, or unavailable for reasons outside our control, including OpenAI rate-limiting, API changes, network conditions, account-side configuration, or model-side adjustments. The App is intended to help you observe trends; it is not a billing system, a contractual record, an audit log, or a substitute for the source of truth provided by your OpenAI account dashboard or invoices. We make no warranty regarding accuracy, completeness, currency, or fitness for any particular purpose, including but not limited to billing reconciliation, audit, business planning, or contractual reporting. You bear sole responsibility for any decision made in reliance on App output.
Acceptable Use
You agree not to: (a) use the App for any unlawful purpose; (b) attempt to reverse engineer, decompile, disassemble, or derive source code from the App, except to the extent that such activity is expressly permitted by applicable law notwithstanding this limitation; (c) circumvent, disable, or interfere with security or rate-limiting features; (d) introduce viruses, malware, or any other malicious code; (e) use the App to harm, harass, defame, or violate the rights of any third party; (f) use the App in any manner that could disable, overburden, or impair its operation or any related infrastructure; (g) use any robot, scraper, or other automated means to access the App without our express written permission; or (h) remove, obscure, or alter any proprietary notice in the App.
Trademarks and Third-Party Services
OpenAI, ChatGPT, GPT, Codex, and Spark are trademarks of OpenAI, Inc. or its affiliates. Anthropic and Claude are trademarks of Anthropic, PBC. Apple, the Apple logo, macOS, iPadOS, and iOS are trademarks of Apple Inc. The App is not affiliated with, endorsed by, sponsored by, or in any way officially connected to OpenAI, Anthropic, Apple, or any other rights holder. All trademarks remain the property of their respective owners. Any reference to these names is for descriptive interoperability only and does not imply any endorsement, partnership, or commercial relationship.
Updates and Discontinuation
We may release updates to the App that introduce new features, change existing features, fix issues, or remove functionality. We may also discontinue the App or any feature at any time, with or without notice. We have no obligation to maintain backward compatibility with prior versions, configurations, or third-party APIs that the App relies on. Changes to OpenAI's authentication mechanisms, quota APIs, product naming, pricing, or terms may affect App functionality and may require an update or, in some cases, may make the App temporarily or permanently inoperable. We do not warrant continued compatibility with OpenAI services or any third-party API.
Termination
These Terms remain in effect until terminated. You may terminate them at any time by uninstalling the App and discontinuing use. We may suspend or terminate your access to the App or any subscription immediately, without notice, if we reasonably believe you have breached these Terms or applicable law, or if continuation would expose us or any third party to legal, regulatory, or reputational risk. Upon termination, all licences granted to you cease and you must cease use of the App. Sections that by their nature should survive termination (including disclaimers, limitation of liability, indemnification, intellectual property, and governing law) will so survive.
Indemnification
You agree to indemnify, defend, and hold harmless MAGRATHEAN UK LTD. and its directors, officers, employees, and agents from and against any and all claims, demands, losses, liabilities, damages, costs, and expenses (including reasonable legal fees) arising out of or relating to: (a) your use or misuse of the App; (b) your breach of these Terms; (c) your violation of any applicable law, regulation, or third-party right; (d) any content or data you transmit through or process with the App; or (e) any decision or action you take in reliance on the App's output.
Limitation of Liability
To the maximum extent permitted by applicable law, in no event shall MAGRATHEAN UK LTD., its directors, officers, employees, or contractors be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or any loss of profits, revenue, data, business opportunity, goodwill, or anticipated savings, arising out of or relating to your use of the App, whether based on contract, tort (including negligence), strict liability, breach of statutory duty, or any other legal theory, and whether or not advised of the possibility of such damages. Our total aggregate liability for any and all claims arising out of or relating to the App or these Terms is limited to the greater of (a) the total amount you paid for the App or any subscription within the twelve (12) months immediately preceding the event giving rise to the claim, or (b) ten pounds sterling (£10). Nothing in these Terms excludes or limits liability for death or personal injury caused by negligence, fraud or fraudulent misrepresentation, or any other liability that cannot lawfully be excluded or limited.
Force Majeure
We are not liable for any failure or delay in performance under these Terms caused by circumstances beyond our reasonable control, including acts of God, natural disasters, war, terrorism, civil unrest, government action, labour disputes, internet or telecommunications failures, third-party service outages (including Apple, Cloudflare, OpenAI, or any other vendor on whose services the App or its supporting infrastructure depends), denial-of-service attacks, or pandemic-related disruption.
Export and Sanctions
The App may be subject to export-control and sanctions laws of the United Kingdom, the United States, and other jurisdictions. You may not use, export, or re-export the App in violation of those laws. By using the App, you confirm that you are not located in, under the control of, or a national or resident of any country to which the UK, US, EU, or UN has imposed a comprehensive embargo, and that you are not on any UK, US, EU, or UN list of prohibited or restricted parties.
Severability and Entire Agreement
If any provision of these Terms is held to be invalid, illegal, or unenforceable by a court or tribunal of competent jurisdiction, that provision shall be severed and the remaining provisions shall continue in full force and effect. Our failure or delay in exercising any right under these Terms shall not constitute a waiver of that right. These Terms, together with the Privacy Policy, the Apple EULA where applicable, and any in-App or App Store-presented terms, constitute the entire agreement between you and MAGRATHEAN UK LTD. concerning the App and supersede all prior or contemporaneous understandings.
Governing Law and Jurisdiction
These Terms and any dispute or claim arising out of or in connection with them or their subject matter (including non-contractual disputes or claims) shall be governed by and construed in accordance with the laws of England and Wales. The courts of England and Wales shall have exclusive jurisdiction to settle any such dispute or claim, except that, where you are a consumer, you may bring proceedings in the courts of the country in which you are habitually resident if and to the extent required by mandatory consumer-protection laws of that country.
Changes to These Terms
We may update these Terms from time to time by publishing a revised version on this page. Material changes will be highlighted on the App or the Magrathean website. Your continued use of the App after a revision takes effect constitutes acceptance of the revised Terms. If you do not agree to a revision, you must stop using the App and uninstall it.
Disclaimer
THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING WITHOUT LIMITATION IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, OR COMPLETENESS. We do not warrant that the App will be uninterrupted, timely, secure, or error-free; that defects will be corrected; that quota readings, history, session-burn analytics, or forecast values will be accurate, complete, or current; that the App will remain compatible with every Mac, iPhone, or iPad; or that the App will remain compatible with any future version of OpenAI services, ChatGPT authentication, macOS, iOS, or iPadOS. Nothing in this disclaimer limits any liability that cannot be limited under applicable law.
