Yanku — Terms of Service

Version: v1.0 Effective date: 2026-05-13 Last updated: 2026-05-13 Language: Published in Estonian and English. Where the two versions diverge, the Estonian version controls. (See §15.)

Scope of this document

These Terms of Service govern access to and use of the Yanku platform (web and mobile apps at app.yanku.eu, business.yanku.eu, and related services).

This document is the platform usage agreement. Two adjacent documents apply alongside it and are referenced in the relevant places below:

• Terms of Sale — contract between an end user and a facility for a specific booking, pass, membership, or product.

• Recurring Payment Terms — additional terms that apply when a user authorises automatic recurring charges (memberships, subscriptions).

• Privacy Policy — how Yanku and facilities process personal data.

Where there is a conflict, the more specific document controls for the matter it addresses.

Three audiences

Yanku is a marketplace platform with three distinct relationships. Sections are scoped accordingly:

1. §2 — Platform terms apply to everyone who accesses Yanku.

2. §3 — Facility operator terms apply to businesses that use Yanku Business to sell bookings, memberships, classes, and services (the "Facility").

3. §4 — End user terms apply to individuals who book or purchase services through Yanku (the "Member").

Users can hold more than one role (e.g., a facility employee who also books a class as a member). Each role's terms apply to the activity carried out in that role.

1. Definitions

• "Yanku", "we", "us" — Yanku OÜ, a private limited company registered in the Republic of Estonia, with registered office at Heki 3, Haabneeme, 74001 Viimsi, Estonia. Yanku and Yanku Business are operated by us.

• "Platform" — the Yanku web and mobile applications, APIs, and supporting infrastructure, including app.yanku.eu and business.yanku.eu.

• "Facility" — a sport club, studio, gym, or similar business that uses the Platform to offer bookings, memberships, classes, courts, professionals, or products.

• "Member" — an individual end user who creates an account on Yanku to book or purchase services from a Facility.

• "Content" — any text, images, video, audio, schedules, prices, or other material uploaded to the Platform.

• "Booking" — a reservation, pass, membership, class registration, appointment, or other service purchase made through the Platform.

• "Payment Processor" — Maksekeskus AS, who handles card and bank-link payments on the Platform.

• "Transaction Fee" — the percentage fee charged by Yanku on each payment processed on a Facility's behalf, as set out in §3.2.

2. Platform terms (apply to everyone)

2.1 Acceptance

By creating an account, signing in, or otherwise using the Platform, you agree to these Terms. If you do not agree, do not use the Platform.

If you accept these Terms on behalf of a company or other legal entity, you represent that you have authority to bind that entity.

2.2 Account security

You are responsible for keeping your account credentials confidential and for all activity carried out under your account. Notify us at info@yanku.eu without undue delay of any unauthorised access or security breach.

We are not liable for losses caused by your failure to safeguard your credentials, except to the extent required by mandatory law.

2.3 Acceptable use

You will not, and will not assist others to:

• access the Platform other than through the official interfaces we provide;

• reverse-engineer, scrape at scale, or replicate the Platform's services;

• upload Content that is unlawful, infringing, defamatory, or harmful to minors;

• interfere with the Platform's operation or attempt to gain unauthorised access;

• use the Platform in violation of applicable EU or Estonian law, or applicable sanctions regimes (EU and UN).

2.4 Suspension

We may suspend or restrict access to the Platform if we reasonably believe these Terms have been breached, if continued access poses a risk to the Platform or other users, or if we are required to do so by law. Where practical we will notify you in advance and give you a chance to cure the issue.

3. Facility operator terms (B2B)

These terms apply between Yanku and a Facility that uses Yanku Business.

3.1 Facility account and authority

The person who creates a Facility account confirms they are authorised to bind the Facility. The Facility is responsible for all activity carried out under its account, including by its staff.

3.2 Fees

Yanku does not charge the Facility a recurring subscription fee for access to Yanku Business.

Yanku charges a Transaction Fee of 4.25% on each payment processed through the Platform on the Facility's behalf. The Transaction Fee is deducted at settlement, before payouts are made to the Facility.

Current fees and any payment-processor pass-through charges are published at https://yanku.eu/pricing. We may change the Transaction Fee for future transactions on at least 30 days' written notice sent to the Facility's billing email. Fee changes do not apply to transactions already processed.

Yanku OÜ is not currently registered for VAT in Estonia; the Transaction Fee is shown net of VAT. We will update these Terms and notify Facilities before the company becomes VAT-registered.

3.3 Amounts owed by the Facility

If a Facility owes Yanku amounts — for example for chargebacks, refunds funded by Yanku ahead of settlement, payment-processor reversals, or other adjustments — those amounts are due on the invoice date. We will normally net these against future payouts where possible.

Unpaid amounts accrue interest at the Estonian statutory commercial default rate under the Law of Obligations Act §113, plus reasonable collection costs. If an invoice remains unpaid for 30 days after written reminder, we may suspend the Facility's access until the balance is settled.

3.4 Facility content and licence

The Facility owns the Content it uploads (class descriptions, photos, schedules, pricing, etc.).

The Facility grants Yanku a non-exclusive, royalty-free, worldwide licence to host, display, distribute, and reproduce the Content solely as necessary to operate, market, and improve the Platform and to display the Facility to Members. The licence ends when the Content is deleted, except for backups and archived copies retained for 60 days for operational and legal-hold purposes.

We do not sub-license the Content to unrelated third parties for analysis, advertising, or resale.

The Facility represents that it has all rights necessary to grant this licence and that the Content does not infringe third-party rights.

3.5 Facility's relationship with Members

The legal contract for a Booking is between the Facility and the Member. Yanku is not a party to that contract; we provide booking, scheduling, and payment-collection services as the Facility's technology and payment-collection agent.

The Facility is solely responsible for:

• the lawful provision of its services and products;

• complying with consumer-protection law (including providing the EU statutory pre-contractual information and honouring statutory withdrawal rights where applicable);

• accuracy of prices, descriptions, schedules, and availability;

• VAT and all other taxes on its sales;

• cancellation, refund, and dispute-resolution policies offered to Members.

3.6 Payouts

Member payments are collected by the Payment Processor and paid out to the Facility, less the Transaction Fee and any chargebacks, refunds, or other adjustments.

Payout cadence is configured by the Facility in Yanku Business as either:

• Next-working-day payouts after each purchase; or

• Weekly payouts.

Details and fee breakdowns appear in the Facility's accounting view in Yanku Business.

3.7 Termination by either party

The Facility may terminate at any time by closing its account in Yanku Business or by written notice to info@yanku.eu. We may terminate for cause (material breach not cured within 30 days of notice; insolvency; sustained chargebacks or fraud). On termination, the Facility's access ends and we will support a reasonable export of its operational data for 30 days.

4. End user terms (B2C)

These terms apply between Yanku and a Member.

4.1 Member account

A Member must be at least 16 years old to create an account. Yanku may require email verification.

4.2 Bookings and payments

When a Member purchases a Booking through the Platform:

• the Member enters a contract for the Booking with the Facility, not with Yanku;

• the price displayed is set by the Facility and includes VAT where the Facility is VAT-registered and required to charge it;

• payment is processed by the Payment Processor and transferred to the Facility, less the Transaction Fee;

• the Member receives a booking confirmation by email.

4.3 Cancellations, refunds, and consumer rights

Cancellation and refund policy is set by the Facility and shown to the Member before payment. The Member should review it before completing a Booking.

EU statutory consumer rights apply in addition to the Facility's policy. In particular:

• the 14-day right of withdrawal under Directive 2011/83/EU applies to most distance contracts with consumers, except for services already fully performed with the consumer's prior express consent and for sport/leisure event services tied to a specific date (Article 16(l)). Most class bookings fall under the Article 16(l) exception once the class date has passed.

• nothing in these Terms or the Facility's policy can override mandatory consumer-protection law.

4.4 Disputes about a Booking

Members should first contact the Facility directly. If the dispute is not resolved, the Member may contact Yanku support at info@yanku.eu for assistance, and may also use:

• the EU Online Dispute Resolution platform: https://ec.europa.eu/consumers/odr/; and

• the Estonian Consumer Disputes Committee where the dispute concerns an Estonian Facility.

4.5 Recurring payments

Memberships and subscriptions billed automatically are governed by the separate Recurring Payment Terms, which the Member accepts when activating a recurring payment.

5. Intellectual property

The Platform, including its software, interfaces, and brand elements (Yanku name, logo, typography, colour system), is owned by Yanku or its licensors. Nothing in these Terms transfers ownership.

Limited, revocable, non-exclusive permission is granted to use the Platform for its intended purpose. Trademarks may be used only with our prior written permission, except for fair informational use (e.g., a Facility identifying that bookings are "powered by Yanku").

6. Third-party services

The Platform integrates with third parties (Payment Processor, mapping, email delivery, analytics, etc.). Their services are subject to their own terms. We are not responsible for outages or errors in third-party services beyond our reasonable control.

7. Disclaimers

To the maximum extent permitted by law, the Platform is provided "as is" and "as available". We do not warrant that the Platform will be uninterrupted, error-free, or fit for any specific purpose beyond what is expressly described in these Terms.

This does not exclude or limit any warranty or liability that cannot be excluded under mandatory Estonian or EU consumer-protection law.

8. Limitation of liability

To the extent permitted by law:

• We are not liable for indirect, incidental, special, or consequential losses, loss of profits, loss of data, or loss of goodwill.

• Our total aggregate liability to a Facility under these Terms in any 12-month period is limited to the Transaction Fees actually retained by Yanku on that Facility's transactions in that period.

• Our total aggregate liability to a Member under these Terms is limited to the fees Yanku itself charged that Member directly in the preceding 12 months (typically zero, since Booking payments flow to the Facility).

These limitations do not apply to liability for intent or gross negligence, for personal injury or death caused by us, or for any other liability that cannot be limited under mandatory law.

9. Indemnification (Facilities only)

A Facility will defend and indemnify Yanku against third-party claims arising from (i) the Facility's services or products, (ii) the Facility's Content, or (iii) the Facility's breach of these Terms or applicable law. We will notify the Facility promptly of any covered claim and cooperate reasonably in the defence.

This section does not apply to Members.

10. Data protection

Yanku and Facilities process personal data as set out in the Privacy Policy and, where applicable, a separate Data Processing Agreement (DPA) between Yanku and the Facility.

11. Changes to these Terms

We may update these Terms. For changes that materially affect rights or obligations:

• Facilities will receive at least 30 days' notice by email or in-app banner before the change takes effect, in line with the P2B Regulation.

• Members will receive at least 14 days' notice by email or in-app banner.

Continued use of the Platform after the notice period means acceptance. If a user does not accept the changes, the Facility may terminate as set out in §3.7 and a Member may terminate by deleting their account.

12. Termination and survival

Either party may terminate as set out above. On termination:

• the user's access ends;

• accrued fees remain payable;

• §§5 (IP), 7 (Disclaimers), 8 (Liability), 9 (Indemnification — Facilities), 10 (Data protection), 13 (Governing law) survive.

We will retain and delete personal data in accordance with the Privacy Policy and applicable law.

13. Governing law and venue

These Terms are governed by the laws of the Republic of Estonia, excluding its conflict-of-laws rules and the UN Convention on the International Sale of Goods (CISG).

The exclusive venue for disputes is Harju Maakohus (Harju County Court), Tallinn, Estonia, subject to:

• a Member's right under EU law to sue or be sued in the courts of the Member State of their habitual residence (Brussels I-bis Regulation Article 18);

• mandatory consumer-protection venue rules; and

• the EU ODR platform and Estonian Consumer Disputes Committee referenced in §4.4.

14. Force majeure

Neither party is liable for delays or failures caused by events outside its reasonable control (natural disasters, war, strikes, internet or upstream service outages, government action, etc.), provided it takes reasonable steps to mitigate the impact.

15. Translations

These Terms are published in Estonian and English. Where there is a conflict between language versions, the Estonian version controls.

16. Miscellaneous

• Entire agreement — these Terms, together with the Privacy Policy, Terms of Sale, Recurring Payment Terms, and any DPA, are the entire agreement between the parties on the subject matter.

• Severability — if any clause is held unenforceable, the remainder remains in force, and the unenforceable clause is replaced with one that most closely reflects its original intent.

• No waiver — failure to enforce a right is not a waiver of it.

• Assignment — the Facility or Member may not assign these Terms without our written consent. We may assign to an affiliate or in connection with a corporate transaction, on notice.

• Notices — to Yanku at info@yanku.eu, or by post to Yanku OÜ, Heki 3-12, Haabneeme, 74001 Viimsi, Estonia; to a Facility or Member at the contact details on their account.
