Terms of Use

Effective 8 October 2026

These Terms of Use ("Terms") govern your use of the ÇayGPT mobile app, the çaygpt.com website and the web panel (together, "ÇayGPT"). By creating a ÇayGPT account or using ÇayGPT, you accept these Terms. How we handle your personal data is explained in our Privacy Policy. The Turkish version of these Terms is at /kullanim-kosullari.

"We", "us" and "our" mean ZincirX Inc., which provides ÇayGPT (section 1). "You" means the person using ÇayGPT. A "venue" is a tea house, coffee shop or similar business listed on ÇayGPT; a "business owner" is a person who registers a venue with ÇayGPT and acts for it.

1. Who provides ÇayGPT

ÇayGPT is provided by ZincirX Inc., a corporation established in the State of Delaware, United States, with its address at c/o Legalinc Corporate Services Inc., 131 Continental Drive, Suite 305, Newark, DE 19713, United States; it is the other party to your contract for using ÇayGPT. ZincirX Bilişim Teknoloji ve Danışmanlık A.Ş. operates the service for it in Türkiye.

Who sells what costs money (voucher packs, certification and monthly membership, section 10) depends on the billing country: the venue's for what is bought for a venue, yours for what you buy for yourself. Your browser's language or where you happen to be does not decide it on its own.

• If the billing country is Türkiye, the seller is ZincirX Bilişim Teknoloji ve Danışmanlık A.Ş. (Gülbahçe Mah. Gülbahçe Cad. İYTE Sitesi No: 1/40 İç Kapı No: 51, 35430 Urla/İzmir, Türkiye; Urla Tax Office 9991441373; MERSİS 0999144137300001). iyzico takes the payment for it, in Turkish lira, on the payment page at zincirx.com; ZincirX A.Ş. issues the invoice.
• For every other country, the seller is ZincirX Inc., a Delaware corporation (registered office: c/o Legalinc Corporate Services Inc., 131 Continental Drive, Suite 305, Newark, DE 19713, United States). Stripe takes the payment through its Stripe account, in US dollars.

Our company details are in section 18.

2. What ÇayGPT is

With ÇayGPT you can:

• find venues near you on a map and in a list, look at their menus and add them to your favourites;
• order from a venue, and book a work table or area;
• buy vouchers, add a voucher code to your credit balance and spend the credit;
• review venues;
• if you choose, say with "Buradayım" ("I'm here") that you are at a venue, see the other members there that day and message them;
• as a business owner, register your venue, manage your menu, receive orders and bookings, buy a membership and certification, and order supplies;
• as a marketer, follow the businesses you referred and your commission in the web panel.

Venues are independent businesses. The products and services on their menus are provided by the venues, the venues set their prices, and the venues prepare the orders. ÇayGPT is the platform that brings you together with venues and passes your order or booking to them.

3. Who may use ÇayGPT

• You must be at least 18 years old to use ÇayGPT and open an account. ÇayGPT is not for anyone under 18; if we learn that someone under 18 has opened an account, we close it.
• Each person may have one account. You may not share an account, or open one for someone else or with false details. Someone whose account we closed for breaking these Terms may not open a new one without our permission.
• You are responsible for keeping the details in your account accurate and up to date.

4. Your account and its security

You can sign in with your email address and password, with Google or with Apple. Do not share your password with anyone. If you think your account has been used without your permission, write to bilgi@çaygpt.com at once; we may suspend the account for a time to protect you and others. You are responsible for what is done with your account to the extent you could have prevented it.

5. Community rules: zero tolerance

ÇayGPT is a community where people meet face to face at real venues. We have zero tolerance for objectionable content and for abusive users. These rules apply to your profile (name, photo, about-me text, profession, social media accounts), your messages, your reviews, venue listings and menus, and to how you treat people you meet through ÇayGPT.

The following are prohibited:

• harassment, bullying, threats, persistent unwanted contact, or following someone;
• hate speech, degradation or discrimination based on race, ethnic origin, religion, sex, sexual orientation, disability or any other characteristic;
• obscene or sexual content, nudity, or unwanted sexual advances;
• content that glorifies or incites violence, or encourages self-harm;
• illegal activity, promoting illegal goods or services, fraud, spam and unsolicited advertising;
• impersonating someone, creating fake accounts, or writing fake or misleading reviews (for example about your own venue or a competitor);
• sharing someone else's personal details (such as a phone number, address or photo) without their permission;
• insults, defamation, or infringing someone else's intellectual property;
• sharing malware or phishing links.

6. Reporting, blocking and moderation

• Reporting: in the app, you can report a user or the content they post. You can also write to bilgi@çaygpt.com.
• Blocking: in the app, you can block a user. You and the person you block no longer see each other in a venue's list of members, can no longer message each other, and any extra details you showed each other are withdrawn. You can unblock at any time.
• Review: we review reports within 24 hours and act on them: we remove content that breaks these rules, and we remove the user who posted it from the social features, for a time or for good, or close their account. For serious or repeated breaches, we may close an account without notice.
• We do not review content before it is posted, but we act on breaches that are reported to us or that we learn of. If someone's life or safety is at risk, or the law requires it, we inform the competent authorities.
• You can contest a decision we made about you by writing to bilgi@çaygpt.com; a person will review it again.

7. Your content

What you put in your profile, messages, reviews and venue listings remains yours. So that we can provide ÇayGPT, you give us a non-exclusive, royalty-free licence to store, copy and display that content within ÇayGPT and pass it to the people concerned, for as long as it is on ÇayGPT. Your reviews are shown publicly with your name and profile photo.

You are responsible for the content you post and confirm that you have the rights needed to post it. We may remove content that breaks these Terms.

8. Business owners' responsibilities

When you register a venue on ÇayGPT:

• you confirm that you are authorised to act for that business;
• you are responsible for the accuracy and currency of the venue's name, address, location, contact details, menu and prices;
• you are responsible for the products and services on your menu, how they are prepared and served, complying with all the law that applies to your business, including food, hygiene, pricing and consumer law, and holding the permits and licences it needs;
• you handle orders and bookings that come through ÇayGPT with care and update their status in good time;
• you use the customer details you see for orders and bookings (name, email address, phone number) only to fulfil that order or booking, keep them secure, and do not use them for marketing without the customer's consent. If you process them for purposes of your own, you are the data controller for that processing under the KVKK;
• you use check-in tags and menu codes only at your own venue.

Venue listings are published after we have reviewed and approved them. We may decline to publish, unpublish or suspend a listing that is inaccurate, misleading or against these Terms.

Purchases you make for your business (membership, certification, supplies) are commercial transactions; consumer protection law does not apply to transactions business owners and marketers make for their business or trade. Where a law nonetheless treats a particular transaction as a consumer transaction, the rights that law gives remain.

9. Orders and bookings

• An order you place is sent to the venue you chose. You pay at the venue or with your ÇayGPT credit.
• You can cancel an order in the app until it is completed. When an order paid with credit is cancelled, its amount goes back to your credit balance.
• You can cancel a booking in the app until it is completed. The venue's own rules (such as how long you may sit) also apply.
• Raise any problem with a product or service with the venue first; if it is not resolved, write to us and we will help.

10. Payments, vouchers and credit

• What costs money: voucher packs; and, for businesses, certification fees and monthly memberships.
• Prices: prices are set in US dollars and are the total you pay; no tax is added on top. Your billing country decides the seller and how you pay (section 1); we ask for it before the payment page opens.
• Buying from Türkiye: the seller is ZincirX Bilişim Teknoloji ve Danışmanlık A.Ş. The dollar price is converted into Turkish lira when you pay, at the Central Bank of the Republic of Türkiye's (TCMB) latest USD forex selling rate, rounded to the whole lira; ÇayGPT shows you the approximate amount beforehand, and iyzico's payment page shows the exact amount before you pay. iyzico takes the payment on the payment page at zincirx.com, and iyzico's terms also apply. ZincirX A.Ş. invoices these sales at 0% VAT (KDV) under the Teknopark exemption; the amount shown is the total, with no VAT on top.
• Buying from anywhere else: the seller is ZincirX Inc. Stripe takes the payment on its own payment page, through ZincirX Inc.'s account, in US dollars, and Stripe's terms also apply.
• Card details: your card details never reach us; iyzico or Stripe takes them on its own page.
• Monthly membership: venues in Türkiye pay for each month in advance: once paid, the membership runs for a month; when the period ends, the next month's invoice opens, and an unpaid one is overdue after 7 days. For venues elsewhere, a membership paid by card renews automatically every month, charged to the card saved at Stripe, until you cancel it. Either way, when you cancel, your membership runs to the end of the period already paid and then does not renew.
• Vouchers: a voucher you buy is a single-use code. The pack's value in Turkish lira (for example ₺500 of credit) is fixed; its price is set in dollars. When the code is used, its value is added to the credit balance of the account that uses it. Anyone who knows the code can use it, so keep it safe.
• Credit: your credit balance is in Turkish lira; you can spend it on orders at participating venues, on certification fees and on the monthly membership. When a dollar-priced fee is paid from credit, its lira equivalent at that day's TCMB USD rate (rounded to the whole lira) is taken from your balance. Credit is not money, and the app has no way to cash it out. When you delete your account, any unused credit balance is deleted with it; use it first, or write to us.
• Refunds: your statutory rights, including those under Türkiye's Consumer Protection Law No. 6502 and its Distance Contracts Regulation, are not affected. Write to bilgi@çaygpt.com about any refund.

11. Intellectual property

ÇayGPT, including its software, design, and the ÇayGPT name and logo, belongs to us or to those who license it to us; open-source components are used under their own licences. These Terms transfer none of those rights to you. We give you a non-exclusive, non-transferable right to use ÇayGPT, for yourself or for your business, as these Terms allow. Except as the law allows, you may not copy, decompile or reverse-engineer ÇayGPT's software, and you may not try to disrupt or overload ÇayGPT or the systems it runs on, or to reach other people's accounts or data.

12. Deleting, suspending and closing accounts

You can delete your account at any time in the app, under Ayarlar (Settings) → Hesabımı Kalıcı Olarak Sil (Delete my account permanently), or by writing to bilgi@çaygpt.com from your account's email address. What is deleted and what is kept is set out in our Privacy Policy.

We may remove content, remove your account from the social features, or suspend or close your account for a breach of these Terms, for a threat to the security of an account, of the service or of others, or where the law, a court or a competent authority requires it. We keep any measure proportionate to its reason and give notice beforehand where waiting would not cause harm.

We may change ÇayGPT's features or end some of them. If we stop providing ÇayGPT altogether, we will tell you at least 30 days before.

13. Liability

We provide ÇayGPT with the care expected of a diligent provider of such a service, but we do not promise that it will run without interruption or error. Maintenance, faults and events outside our control can make it unavailable for a time.

We are not responsible for the products and services venues provide, for other users' content and behaviour (without prejudice to how we handle reports under these rules), or for the services of third parties such as Google, Apple, Stripe and iyzico.

Nothing in these Terms excludes or limits our liability for intent or gross negligence, for injury to life, body or health, or any other liability that the law does not allow to be excluded or limited, and nothing affects your statutory rights as a consumer. Apart from those cases, for damage caused by slight negligence we are liable, to the extent the law allows, only for foreseeable and typical damage.

You compensate us for the losses we incur from third-party claims that result from your content or your breach of these Terms, to the extent you are responsible for them.

14. If you downloaded the app from the App Store

• These Terms are between you and ZincirX Inc., not Apple; we, not Apple, are responsible for the app and its content.
• Apple has no obligation to provide any maintenance or support services for the app.
• If the app fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price, if any, that you paid for the app. To the extent the law allows, Apple has no other warranty obligation with respect to the app.
• We, not Apple, are responsible for addressing any claims relating to the app, including product liability claims, claims that it fails to conform to any legal or regulatory requirement, and claims under consumer protection law.
• We, not Apple, are responsible for the investigation, defence, settlement and discharge of any claim that the app infringes a third party's intellectual property rights.
• You represent that you are not located in a country that is subject to a US Government embargo or has been designated by the US Government as a "terrorist supporting" country, and that you are not listed on any US Government list of prohibited or restricted parties.
• You must comply with any applicable third-party terms (such as your mobile operator's) when you use the app.
• Apple and its subsidiaries are third-party beneficiaries of these Terms and, once you accept them, have the right to enforce them against you.

15. Changes

We may change these Terms for a valid reason, such as a change in the law or in ÇayGPT. A change that reduces your rights or adds to your obligations takes effect only after we have told you, in the app or by email, at least 30 days before; if you do not accept it, you can delete your account free of charge. Other changes, such as corrections and clearer wording, take effect when we publish them. The date at the top shows the version in force.

16. Governing law and disputes

These Terms, and every contract made under them, are governed by the law of the State of Delaware, United States, without regard to its rules on conflict of laws. The one exception is ZincirX A.Ş.'s sales to buyers in Türkiye (section 1), which are governed by Turkish law.

If you are a consumer, this choice does not take away the protection of the mandatory consumer rules of the country where you habitually live, which, if you live in Türkiye, means Turkish consumer law. You can bring a dispute before the consumer arbitration committee (tüketici hakem heyeti) or the consumer court where you live.

For disputes with users who act for their business or trade (such as business owners and marketers), the state and federal courts sitting in Delaware have exclusive jurisdiction.

If a provision of these Terms is invalid, the rest remain in force. If a problem arises, please write to us first so that we can try to resolve it; that is not a condition of going to court.
