Terms of use

Last updated: 17 October 2026

1. Agreement and acceptance

These terms of use are an agreement between you and Seyfi Can Zeyrek, an individual trading as Morrowline Apps ("we", "us"), about your use of the Ketogo app for iOS and Android, its notifications, the Premium subscription and the related pages on our website.

By downloading, installing or using the app you agree to these terms. If you do not agree, do not use the app. During onboarding the app asks you to confirm its health note with the button "I understand and I'm 18 or older"; that button records your acknowledgement of the health note and your age. Our privacy policy explains how we handle personal data (section 15).

2. Definitions

"App" means the Ketogo mobile application (application ID com.eggo.keto.diet) and its updates.
"Service" means the features of the App, including meal plans, recipes, food and water logging, nutrition targets, notifications and ads.
"Premium" means the paid subscription that unlocks additional features and removes ads.
"Content" means recipes, food data, plans, texts, images and other material we provide in the App.
"Stores" means the Apple App Store and Google Play.

3. Eligibility and age

You must be at least 18 years old to use the App. By using it you confirm that you are 18 or older and that you can enter into this agreement under the law where you live. The App is not directed to children.

4. Your account

The app creates an anonymous account identifier when you first open it; it is not tied to your name unless you add one. You do not register with an email address or password. The identifier lets the App download content, check Premium and send the notifications you allow.

Your plan, logs and settings are stored on your device. If you uninstall the App or change devices, they cannot be restored by us; Premium can be restored with the same Store account (section 11). The App does not yet have an in-app option to delete the identifier; you can ask us to delete your data by email, as described in the privacy policy.

5. License to use the app

We grant you a personal, non-exclusive, non-transferable, revocable license to use the App on devices you own or control, for your private, non-commercial use, under these terms and the rules of the Store you downloaded it from.

You must not copy, modify, distribute, sell or rent the App or the Content, reverse engineer or decompile the App (except where the law allows it despite this restriction), or circumvent its technical limits, including the limits of the free version. We keep all rights not expressly granted.

If you downloaded the App from Google Play, Google is not a party to these terms. Purchases are processed under Google Play's terms of service. These terms do not give you rights against Google.

6. Apple App Store terms

If you downloaded the App from the Apple App Store, the following also applies:

Acknowledgement. These terms are between you and Seyfi Can Zeyrek (trading as Morrowline Apps) only, not with Apple Inc. ("Apple"). We, and not Apple, are solely responsible for Ketogo (the "Licensed Application") and its content. These terms do not override Apple's Media Services Terms and Conditions.
Scope of license. The license we grant you is non-transferable and limited to Apple-branded products that you own or control, and as permitted by the Usage Rules set out in Apple's Media Services Terms and Conditions (including use through Family Sharing or volume purchasing where Apple allows it).
Maintenance and support. We, and not Apple, are solely responsible for maintenance and support of the Licensed Application, as set out in these terms or as required by law. Apple has no obligation to provide maintenance or support.
Warranty. If the Licensed Application fails to conform to an applicable warranty, you may notify Apple, and Apple will refund the purchase price for the Licensed Application to you (if any). To the maximum extent permitted by law, Apple has no other warranty obligation for the Licensed Application. Other claims, losses, liabilities, damages, costs or expenses caused by a failure to conform to a warranty are our responsibility.
Product claims. We, and not Apple, are responsible for addressing claims by you or a third party relating to the Licensed Application or your possession and use of it, including product liability claims, claims that it fails to meet a legal or regulatory requirement, and claims under consumer protection, privacy or similar laws. Nothing in these terms limits our liability beyond what the law allows.
Intellectual property. If a third party claims that the Licensed Application or your possession and use of it infringes that party's intellectual property rights, we, and not Apple, are solely responsible for the investigation, defence, settlement and discharge of the claim.
Legal compliance. You confirm that you are not located in a country that is subject to a US Government embargo or designated by the US Government as a "terrorist supporting" country, and that you are not on any US Government list of prohibited or restricted parties.
Developer contact. Questions, complaints or claims about the Licensed Application can be sent to Seyfi Can Zeyrek (trading as Morrowline Apps), Esenyali Mahallesi 52/75 Sk. Izmir/Türkiye, email zeyrekseyfican@gmail.com.
Third-party terms. You must comply with the third-party terms that apply when you use the Licensed Application (for example, the terms of your mobile data provider).
Third-party beneficiaries. Apple and its subsidiaries are third-party beneficiaries of these terms. Once you accept them, Apple has the right (and is considered to have accepted the right) to enforce these terms against you as a third-party beneficiary.

7. Device permissions

The App asks for notification permission (for reminders) and, on iOS, for permission to track (for personalized ads). Both are optional: you can refuse them or revoke them at any time in your device settings, and every feature and Premium remain available. If you turn off notifications you will not receive reminders. The privacy policy explains each permission.

8. The service and its limits

Ketogo helps you follow a ketogenic diet: it calculates nutrition targets from your onboarding answers, builds meal plans, offers keto recipes and food data and lets you log food, water and activity. Your profile answers, nutrition targets, meal plans and food, water and activity logs are stored on your device. We also process identifiers, app usage events, crash reports, advertising data and subscription status in the cloud with Google (Firebase), Google (AdMob) and RevenueCat to run the app, keep it stable, show ads and check subscriptions.

Limits of the Service:

Nutrition values, macro targets and plan suggestions are estimates and can be inaccurate. Food values vary by brand, portion and preparation; the label on a product is the more reliable source.
Some features are free and some need Premium. In the free version some meals and recipes are locked; you can open them by watching a rewarded video or with Premium. What is free can change; the App shows what a purchase unlocks before you buy.
Recipes and food data are downloaded from our servers and need an internet connection the first time and when they are updated.
Premium status depends on confirmation from the Store and RevenueCat, which can take a moment or fail temporarily.
The Service depends on your device, your operating system, your connection and services run by others (the Stores, Google and notification services). We do not promise uninterrupted or error-free operation.
Features, Content and limits can change as we improve the Service. We may discontinue the App with reasonable notice where practical.
We do not promise any particular weight, health or other outcome from using the App.

9. Acceptable use

You must not:

use the App for any unlawful purpose or in breach of these terms;
copy, scrape or extract the recipes, food data or other Content in bulk, or use automated means to access the Service;
bypass the limits of the free version, the paywall or the rewarded video mechanism, or interfere with ads in a way that defrauds advertisers;
attack, overload or interfere with our servers, App Check or the push system, or try to gain unauthorized access;
resell, sublicense or commercially exploit the App or the Content;
misrepresent your age or use the App if you are under 18;
use the App in breach of export control or sanctions laws.

If you break these rules we may warn you, limit features or suspend your access (section 19). Report problems to zeyrekseyfican@gmail.com.

10. Health and wellness

The app is a wellness tool, not a medical device. It does not diagnose, treat or prevent any condition. It does not give medical advice. Talk to a doctor or dietitian before starting a ketogenic diet or changing your eating or exercise routine, especially if you are pregnant or breastfeeding, have diabetes, a kidney, heart or other chronic condition, high blood pressure, take regular medication or have a food allergy. Nutrition values, targets and plans can be inaccurate. Check ingredients and product labels for allergens. Do not rely on the App in an emergency. You use the App and its suggestions at your own risk. Stop and seek medical help if you feel unwell.

Goals you choose in the App, such as losing weight, are your own choices and not a promise of a result.

11. Purchases and subscriptions

Premium is sold as weekly and annual subscriptions through the App Store or Google Play (the "Store"). The price and billing period are shown in the App and in the Store before you buy. Taxes may apply.

Billing. Payment is charged to your Store account when you confirm the purchase. We do not receive or store your card details; the Store processes payment.
Renewal. Subscriptions renew automatically until you cancel in your App Store or Google Play account settings. Your Store account is charged for each new period unless you cancel at least 24 hours before the current period ends.
Cancellation. Cancel any time in your Apple ID settings (Settings > Apple ID > Subscriptions) or in Google Play (Payments & subscriptions > Subscriptions). Deleting the App does not cancel a subscription. After cancelling you keep Premium until the end of the paid period.
Refunds. Refunds are handled by Apple or Google under their own rules. Ask the Store for a refund; we cannot refund Store purchases ourselves. This does not affect rights you have by law (section 16).
Restore. Use "Restore purchases" in Profile, or the restore link on the subscription screen, with the same Store account to get Premium back on a new device or after reinstalling.
Price changes. If the price of a subscription changes, the Store tells you before the change applies, and you can cancel before it takes effect.
What Premium includes. Premium unlocks all meals and recipes in the App and removes ads while it is active. We may change Premium features, and we tell you about material reductions in advance.

12. Advertising

The free version shows ads served by Google (AdMob); Premium subscribers do not see ads. Ads come from third-party advertisers. We do not control their content and do not endorse the advertised products. Rewarded videos are optional. Your choices about personalized ads (Google's consent form, Apple's tracking prompt and your device's ad settings) are described in the privacy policy.

13. Third-party services

The App relies on services we do not control: the Stores, Google (Firebase), Google (AdMob), RevenueCat and the push services of Apple and Google. Their own terms apply to your use of them. Links in the App to our website or to the Stores open services with their own terms. We are not responsible for the content or availability of third-party services, to the extent the law allows.

14. Intellectual property

We and our licensors own the App, its design, the recipes, food data, images, texts and the Ketogo name and logo. These terms do not give you any right to use our trademarks. If you send us feedback, we may use it without obligation to you. Open-source components in the App are licensed under their own licenses.

15. Privacy

Our privacy policy explains how we handle personal data when you use the App: https://ketoeggo.morrowline.app/en/privacy/. If you live in Türkiye, our information notice under Law No. 6698 is at https://ketoeggo.morrowline.app/en/kvkk/.

16. Your rights as a consumer

Nothing in these terms limits rights you have as a consumer under the law of the country where you live and that cannot be waived by agreement.

EU and UK. If you buy Premium as a consumer in the EU or UK, you have a 14-day right to withdraw from a distance contract. For digital content or a digital service supplied immediately, you lose this right if you expressly asked for immediate supply and acknowledged that you lose it; for a digital service you asked us to start during the withdrawal period, you pay a proportionate amount for the period used. You make the withdrawal or refund request through the Store's purchase history or refund function. Digital content and services must be as described, of satisfactory quality and fit for purpose; if they are not, you may be entitled to have them brought into conformity, a price reduction or termination (EU Directives 2019/770 and 2011/83, UK Consumer Rights Act 2015).

Türkiye. Your rights under Law No. 6502 on Consumer Protection and its regulations, including the Distance Contracts Regulation and the rules on unfair terms, remain in force.

17. Disclaimer of warranties

THE APP AND THE SERVICE ARE PROVIDED "AS IS" AND "AS AVAILABLE". We do not warrant that they will be uninterrupted, error-free or suitable for a particular purpose, or that nutrition values and plans are accurate. Rights that the law gives you and that cannot be excluded remain. For iOS, Apple's refund route in section 6 (clause 4) applies.

18. Limitation of liability

We are not liable for indirect or consequential loss, lost profits, lost data or loss of goodwill, to the extent the law allows.

Our total liability to you for all claims about the App is limited to the amount you paid for Premium in the 12 months before the event giving rise to the claim, or 50 euros if you paid nothing, to the extent the law allows.

Nothing in these terms limits liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, for intent or gross negligence, or for anything that cannot be limited by law, including your statutory consumer rights. This section does not affect Apple's refund route or Apple clause 5 in section 6.

19. Termination

You can stop using the App at any time and uninstall it. Uninstalling removes the data on your device but does not delete the data we hold or cancel a subscription; you can ask us to delete your data as described in the privacy policy, and cancel a subscription in the Store.

We may suspend or end your access if you seriously or repeatedly break these terms, if the law requires it, or to protect the Service or others. We tell you in advance where practical. When your access ends your license ends. What happens to your data is described in the privacy policy. Sections about intellectual property, warranties, liability, disputes and anything meant to continue stay in force.

20. Governing law and disputes

Talk to us first. If you have a complaint, write to zeyrekseyfican@gmail.com. We will try to resolve it within 30 days before either of us starts formal proceedings. This does not affect your right to go to court or to a consumer authority at any time.

Governing law. These terms are governed by the laws of the Republic of Türkiye, without regard to conflict-of-law rules. If you are a consumer, mandatory consumer protection rules of the country where you live continue to apply to you.

Courts. The courts of İzmir, Türkiye have non-exclusive jurisdiction. If you are a consumer, you may also bring a claim in the courts of the place where you live, and we can only bring a claim against you in the courts of that place, to the extent the law of your country says so. Consumers in Türkiye may also apply to the consumer courts and consumer arbitration committees of their place of residence. Small-claims procedures where you live remain available to you.

There is no arbitration clause and no class-action waiver in these terms.

21. Changes to these terms

We may change these terms when the App, the law or our business changes. We update the "Last updated" date and, for material changes, tell you in the App before they apply, at least 30 days in advance where we can. If you continue to use the App after the changes take effect, the new terms apply; if you do not agree, stop using the App and cancel any subscription in the Store. Where the law requires your consent to a change, we ask for it.

22. General

If a provision of these terms is invalid, the rest remains in force. If we do not enforce a right, we do not waive it. These terms and the privacy policy are the entire agreement between you and us about the App. We may transfer these terms to a successor who takes over the App; your rights as a consumer are not reduced by the transfer. Notices to you are given in the App or in the Store listing. If these terms are translated, the English version prevails to the extent the law allows. No one other than you, us and, under section 6, Apple has rights under these terms.
