Terms of Use

KelimeYAP EN · Last updated: 16 August 2026

The short version

KelimeYAP EN is a word-learning app you may use for personal, non-commercial learning. There is no account and nothing to sign up for. Don't scrape it, reverse-engineer it or try to game the credit system. Subscriptions are billed, renewed and refunded by Apple and Google, not by us. In-app credits are not money and have no cash value. The app is provided as it is, and your mandatory consumer rights are unaffected by anything below.

These Terms of Use ("Terms") govern your use of the KelimeYAP EN mobile app, published on the App Store (com.furkanyanteri.kelimeyap-en-tr) and Google Play (com.furkanyanteri.kelimeyapentr) by ObliqueX (KelimeYAP), a software studio based in Ankara, Türkiye ("KelimeYAP", "we", "us"). How we handle data is described separately in our Privacy Policy.

1. Accepting these Terms

By using KelimeYAP EN you agree to these Terms. During onboarding the app states that continuing means you accept the Terms of Use and the Privacy Policy, and links to both pages. Continuing past that step, and every later use of the app, confirms your acceptance.

If you do not agree with these Terms, do not use the app. You can stop at any time by deleting it from your device.

2. Age requirement

KelimeYAP EN is not intended for children under 13. If you are between 13 and 18, or under the age of majority where you live, you may use the app only with the consent of a parent or legal guardian, who accepts these Terms on your behalf. This matches the children's privacy section of our Privacy Policy.

3. What the app is, and what it is not

KelimeYAP EN helps you learn English vocabulary through word cards, quizzes, visual hints and audio questions. The learning content — word definitions, example sentences, level labels — is educational material. It is not an academic, professional or official qualification, it does not certify your level of English, and it should not be relied on as a substitute for formal instruction or assessment.

We do not promise any particular learning outcome. How much you learn depends on how you use the app.

Much of the app works offline, but some features need a connection — visual hints, quiz setup and rewarded video among them.

4. Your licence, and what belongs to us

We grant you a limited, non-exclusive, non-transferable, revocable licence to use KelimeYAP EN for your own personal, non-commercial learning, on devices you own or control. That licence is all you get; no ownership passes to you.

The following are ours and may not be used without our permission:

The app itself, its design, interface, brand name and logo.
The visual hint photographs, produced specifically for this app.
The sound effects, synthesised specifically for this app.
The peak/journey artwork and the badge designs.
The in-app text and the compiled learning content.

Word lists are compiled from publicly available dictionary sources. The compilation, editing and everything generated on top of it — example sentences, images, audio, structure — belong to KelimeYAP.

5. Acceptable use

You agree not to:

Scrape, bulk-download or copy the app's content, in whole or in part.
Reverse-engineer, decompile or disassemble the app or our servers, or attempt to derive their source code.
Access the app using automated tools, bots or scripts.
Attempt to reach our APIs or servers directly, from outside the app.
Manipulate, or attempt to manipulate, the rewarded-video system, the credit economy or progress transfer.
Redistribute, sell, rent or sublicense the app.
Circumvent or attempt to circumvent any security measure.

Except where the law expressly gives you a right that cannot be waived — for instance certain rights to decompile for interoperability — these restrictions apply in full.

6. Usage limits and restriction of access

The app applies rate limits to image and quiz requests, measured per minute and per hour, to keep the service available for everyone.

If unusual or abusive usage is detected, we may restrict your access temporarily, in escalating steps. In serious or repeated cases the restriction may be permanent. This detection can be automated, which means it can occasionally be wrong.

If you believe your access was restricted by mistake, write to info@obliquex.com and we will look at it.

7. Advertising

The free version shows ads through Google AdMob. The content of those ads is determined by Google and its advertisers, not by us, and we are not responsible for advertising content or for anything an advertiser offers you.

Whether ads are personalised depends on your consent — through Google's User Messaging Platform in the EU, UK and Switzerland, and additionally through Apple's App Tracking Transparency on iOS. Declining does not restrict any feature. The details are in the Privacy Policy.

8. KelimeYAP Pro: subscription, payment and refunds

KelimeYAP Pro removes ads and unlocks additional features. It is offered as a monthly, three-month or yearly plan.

Payment runs entirely through the Apple App Store or Google Play. We never see, handle or store your payment details.
Renewals, cancellations and refunds are governed by the rules of the platform you bought from. Requests go to Apple or Google — not to us. We are not able to issue a refund on their behalf.
A subscription renews automatically until you cancel it. You cancel from your account settings in the App Store or Google Play, and cancelling takes effect at the end of the paid period.
Prices vary by country and may change. A price change never affects a period you have already paid for.

Where you have a statutory right of withdrawal as a consumer, that right applies regardless of this section.

9. In-app credits

The app uses a virtual unit called credits. Credits are spent as you move through cards, and earned by watching rewarded video or completing quizzes.

Credits have no monetary value.
They cannot be transferred to real money, to another person, or anywhere outside the app.
They cannot be bought — they are only earned through use.
They cannot be refunded or exchanged for cash.
We may change the rates at which credits are earned and spent.
If the service ends, no compensation can be claimed for unused credits.

10. Progress transfer

The app lets you turn your own progress into a transfer code and copy it to another device. This is a feature you trigger yourself.

Sharing that code is your responsibility. Anyone who has it obtains a copy of your progress. We cannot tell whether the person using a code is you, and we are not responsible for the consequences of a code you shared or exposed.

11. Availability, warranties and your data

KelimeYAP EN is provided "as is" and "as available". To the fullest extent permitted by law, we make no warranties of any kind, express or implied, and we do not warrant that the app will be uninterrupted, timely, secure or error-free, or that defects will be corrected.

Your progress can be lost. It is held on your device and on our servers, but losing your device, deleting the app, a platform change or a technical failure can all mean your progress is gone. The app has no account system to fall back on, so we cannot restore progress for you. If your progress matters to you, use the transfer feature described in section 10.

12. Limitation of liability

To the fullest extent permitted by applicable law, KelimeYAP is not liable for any indirect, incidental, special, punitive or consequential damages, nor for loss of data, loss of learning progress, loss of profit or loss of opportunity, arising from or connected to your use of — or inability to use — the app.

Where liability cannot be excluded, it is limited to the amount you paid us for the app in the twelve months before the event giving rise to the claim. If you use the free version, you have paid us nothing, and that amount is zero.

Nothing in these Terms limits anything that cannot lawfully be limited. This includes liability for death or personal injury caused by negligence, for fraud, and any mandatory rights you have under consumer protection law — in particular under EU and UK consumer law, and under Turkish consumer legislation (Law No. 6502). Those rights apply in full regardless of the two paragraphs above.

13. Changes to the service

We may add, change or remove features. We may also discontinue the app entirely; if we do, we will make a reasonable effort to give notice in advance. You can end your use at any time by deleting the app from your device.

14. Changes to these Terms

We may update these Terms. The current version is always the one published on this page, and the "last updated" date at the top shows when it changed. For significant changes we may also notify you inside the app. Continuing to use the app after a change means you accept the updated Terms.

15. Governing law, jurisdiction and consumer rights

These Terms are governed by the laws of the Republic of Türkiye. The courts and enforcement offices of Ankara, Türkiye have jurisdiction over disputes arising from them.

If you are a consumer, this does not take away your local protection. Choosing Turkish law and Ankara courts does not deprive you of the protection given by the mandatory consumer law of the country where you live, and it does not prevent you from bringing proceedings in your local courts where the law gives you that right. Consumers in Türkiye may also apply to the consumer arbitration committees and consumer courts available to them.

16. Severability and waiver

If any provision of these Terms is found invalid or unenforceable, the rest stays in force, and the invalid provision is treated as replaced by the closest valid one. If we do not enforce a right, that is not a waiver of it, and it does not stop us enforcing it later.

17. Additional terms for App Store downloads

The following applies if you downloaded KelimeYAP EN from the Apple App Store. Where it conflicts with the rest of these Terms, this section wins for that download.

These Terms are between you and KelimeYAP only, not with Apple. Apple is not a party to this agreement.
Apple is not responsible for the app or its content.
Maintenance and support are our responsibility, not Apple's. Apple has no obligation to provide any support for the app.
If the app fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price. To the maximum extent permitted by law, that is the whole of Apple's warranty obligation, and Apple has no other liability of any kind in connection with the app.
We, not Apple, are responsible for addressing any claim that the app infringes a third party's intellectual property rights, and for any product liability claim, any claim that the app fails to meet a legal or regulatory requirement, and any claim under consumer protection or similar legislation.
Apple and its subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance Apple has the right to enforce them against you as a third-party beneficiary.
You confirm that you are not located in a country subject to a US Government embargo or designated as a "terrorist supporting" country, and that you are not on any US Government list of prohibited or restricted parties.
