Terms of Service

Updated on October 19, 2026

These Terms of Service (the “Terms”) govern (a) the use of the website leika.pro (the “Website”) and (b) the performance marketing services provided by LEIKA PRO LIMITED, a company incorporated in Hong Kong with Company Registration Number 81344073 and its registered office at RM 511, 5/F, Ming Sang Ind Bldg, 19-21 Hing Yip Street, Kwun Tong, Hong Kong (“LEIKA.PRO”, “we”, “us”).

By using the Website, submitting a request, signing an Insertion Order or paying an invoice, you (the “Client”) agree to these Terms. If you act on behalf of a company, you confirm that you are authorised to bind that company.

1. Who we work with

Our services are provided exclusively to businesses (B2B) that own or are authorised to market an existing product or service (“Advertisers”). We do not offer services to consumers, and the Website is not intended for persons under 18.

2. Our services

LEIKA.PRO is a performance marketing agency. Depending on the agreed scope, our services may include:

  • marketing strategy and media planning;
  • purchasing and managing advertising on third-party platforms such as Meta (Facebook, Instagram), Google Ads and TikTok, and campaigns with influencers and content creators;
  • production of ad creatives, landing pages and funnels;
  • set-up of conversion tracking, postbacks and analytics;
  • campaign optimisation and performance reporting.

The exact scope, target actions, markets, pricing model, prices and reporting for each engagement are set out in a written proposal, insertion order or service agreement accepted by both parties (an “Insertion Order”). If an Insertion Order conflicts with these Terms, the Insertion Order prevails for that engagement.

3. How an engagement starts

  1. You submit a request through the Website or contact us directly.
  2. We review your product, markets and goals and may decline any project at our discretion (see section 7).
  3. We send a proposal with the pricing model, prices per result and any prepayment required.
  4. The engagement starts when you accept the Insertion Order and, where applicable, pay the prepayment and provide tracking access.

4. Pricing models

We charge for results, not for time or ad impressions. One or a combination of the following models is agreed in each Insertion Order:

  • CPL (cost per lead) — a fixed price for each qualified lead or targeted call that meets the agreed criteria;
  • CPA (cost per action) — a fixed price for each agreed action, such as a registration, trial start, install or first payment;
  • CPS (cost per sale) — a fixed amount or percentage for each completed sale;
  • RevShare (revenue share) — an agreed percentage of the revenue you receive from customers we acquire, for the period stated in the Insertion Order;
  • Hybrid — a combination of a fixed price per action and a revenue share.

Unless the Insertion Order states otherwise, advertising spend on third-party platforms, creative production and campaign management are included in the price per result, and you are not charged for impressions, clicks or hours worked. All prices are quoted in US dollars (USD) and exclude any taxes, which are payable by the Client where applicable. More information is available on our Pricing page.

5. Tracking, validation and reporting

  • Source of truth. Billable results are counted from the Client’s own system (via postback, API or an agreed tracking platform). You agree to provide and maintain the tracking access needed to confirm results.
  • Validation window. You may review results and reject invalid ones within the validation period stated in the Insertion Order (7 days by default from the date the result is reported).
  • Invalid results include duplicates, test entries, results generated by fraud or automated traffic, and results that do not meet the agreed criteria. Invalid results are not billed; if already paid, they are credited against the next invoice or refunded under our Refund & Cancellation Policy.
  • Results not disputed within the validation period are deemed accepted.
  • We provide access to reporting showing results by campaign and channel, and summary reports at the frequency set in the Insertion Order.

6. Invoicing and payment

  • Prepayment. For new Clients we may require a prepaid balance before campaigns go live. Validated results are deducted from the prepaid balance, and you will be asked to top it up when it runs low.
  • Invoices. Where services are billed in arrears, we invoice weekly or monthly for validated results, as set out in the Insertion Order. Each invoice lists the number of billable results, the price per result and the total amount due.
  • Payment term. Invoices are payable within 7 days of issue unless the Insertion Order states otherwise.
  • Payment methods. We accept bank transfer and card payments. Card and online payments are processed by our licensed payment service providers; we do not store full card details.
  • Late payment. If an invoice is overdue, we may pause campaigns until payment is received.
  • Payment disputes. If you believe a charge is incorrect, please contact us at contact@leika.pro before initiating a chargeback, so we can resolve it promptly.

7. Client responsibilities and acceptable products

You confirm that:

  • you own or are authorised to market the product or service being promoted, and that it, its landing pages and all materials you provide are lawful in each target market;
  • you hold all licences, permits and rights required for your product and your marketing claims;
  • your product complies with our Acceptable Use Policy and with the advertising policies of the platforms we use;
  • you will handle your customers’ personal data, payments, refunds and support in line with applicable law.

We may refuse, pause or stop campaigns for any product that breaches these Terms, the Acceptable Use Policy, platform rules or applicable law.

8. No guarantee of results

Marketing results depend on many factors outside our control, including your product, pricing, website, funnel, market conditions and third-party platforms. Forecasts, estimates, case studies and calculator results on the Website are illustrative only and are not a guarantee of any volume, revenue or return on investment. Because you pay only for validated results, you are not charged for campaigns that do not deliver results, except for any fixed fees expressly agreed in the Insertion Order.

9. Intellectual property

  • You keep all rights in your brand, trademarks, product and the materials you provide, and grant us a non-exclusive licence to use them only to deliver the services.
  • Creatives produced specifically for you and paid for under an Insertion Order are transferred to you on full payment, unless otherwise agreed.
  • Our know-how, tools, templates, internal data and methodology remain our property.
  • The Website, the LEIKA.PRO name and logo belong to LEIKA PRO LIMITED and may not be copied or reused without our written permission.

10. Confidentiality

Each party will keep confidential the other party’s non-public business information (including prices, performance data and customer data) and use it only to perform the engagement, except where disclosure is required by law.

11. Personal data

Our handling of personal data is described in our Privacy Policy and Cookie Policy. Where we process your customers’ personal data on your behalf (for example, lead details), we do so only on your instructions and for the purpose of the engagement, and the parties will sign a data processing agreement where required by law.

12. Limitation of liability

To the maximum extent permitted by law: (a) neither party is liable for indirect, incidental or consequential losses, including loss of profit, revenue or goodwill; and (b) our total liability under or in connection with an engagement is limited to the amounts paid by the Client for that engagement in the three (3) months before the event giving rise to the claim. Nothing in these Terms limits liability that cannot be limited by law, including liability for fraud.

13. Term, suspension and termination

  • Either party may end an engagement by giving written notice (email is sufficient) with the notice period stated in the Insertion Order, or 7 days if none is stated.
  • Either party may terminate immediately if the other materially breaches these Terms and does not remedy the breach within 5 business days of notice.
  • On termination, the Client pays for validated results delivered up to the termination date. Any unused prepaid balance is refunded in accordance with our Refund & Cancellation Policy.

14. Use of the Website

You agree not to misuse the Website, including by attempting unauthorised access, interfering with its operation, submitting false information, or using automated means to submit requests or collect data. Content on the Website, including blog articles, is provided for general information only.

15. Changes to these Terms

We may update these Terms from time to time. The current version, with the date it was last updated, is published on this page. Changes do not affect Insertion Orders already in progress unless both parties agree.

16. Governing law and disputes

These Terms and any engagement are governed by the laws of the Hong Kong Special Administrative Region. The parties will first try to resolve any dispute amicably. If a dispute cannot be resolved within 30 days, it will be submitted to the exclusive jurisdiction of the courts of Hong Kong.
