Terms of Use

Last updated: 12 November 2026

These terms govern the use of the Kosto service. Read them before creating an account. When you create an account, you indicate that you accept the terms by ticking the checkbox on the sign-up form; no account is created without ticking it.

1. Parties

Service provider (seller and data controller): Ahmet Budak, a sole proprietorship trading under the name “Kosto” (“Kosto”, “we”). Tax office: Akşehir. Place of business: Akşehir, Konya, Türkiye. Contact: support@getkosto.com. Kosto is not a company and has no MERSİS number or KEP address.

The natural person or legal entity using the service is regarded as the “user” (“you”). If you open the account on behalf of a company, you represent that you have the authority to bind that company.

2. Description of the service

Kosto is a subscription-based web service that measures domain names and websites in terms of search visibility. The service includes the following tools:

• Domain metrics. Authority score, referring domains, spam footprint and archive history check, domain comparison and bulk query.
• Site and publisher tools. Site audit, publisher report, competitor and gap report, placement check and watchlists.
• Search data. Estimated organic traffic, ranking keywords, keyword research (search volume, cost per click, difficulty), keyword gap, page-level backlink lists and rank tracking. This data is retrieved when you request it and is measured in data credits (see Section 5).
• API. Programmatic access to the same metrics, if your plan permits.

Which tool is offered in which plan and with which limit is shown on the pricing page. We may add, change or remove tools; we will not materially narrow the scope of a paid period within that period.

Kosto is a measurement tool. Traffic, search volume and ranking figures are estimates; they are not actual visit counts or exact rankings (see Section 4).

3. Account and security

• A valid email address is required to open an account. You are responsible for the accuracy and currency of your information.
• Persons under 18 years of age may not use the service.
• You are responsible for keeping your password and API keys confidential. You are responsible for actions made with a key or from your account. If you suspect unauthorized use, notify us immediately.
• The account is personal; it cannot be transferred or sold. Shared use by multiple people is allowed only to the extent your plan permits.

4. Nature of the results

Every score and flag produced by Kosto is an estimate. Use it with knowledge of the limits below.

• Authority scores, estimated traffic, search volume and ranking figures, spam footprint checks and archive findings are produced from data compiled from third-party data and infrastructure providers and from publicly available sources. This data may be incomplete, delayed or inaccurate. The results are not a definitive determination; they are based on sampling.
• The phrase “No signal found” does not mean that something does not exist; it indicates that no trace was found in the data examined. The “Looks clean” label is likewise not a guarantee.
• Kosto makes no promise of rankings, traffic, revenue or any business result. Using the service does not secure any of these.
• Decisions such as buying a domain name, obtaining a link from a site or placing content on a site are entirely yours. We recommend that you do not base your decision solely on Kosto results but support it with your own review.
• The flagging of a site as “has spam traces” or “publishes advertising / guest author pages” is not a legal characterization, accusation or determination about that site. To object to a flag, you can write to support@getkosto.com; we review the objection within a reasonable time.

5. Plans, data credit and payment

• Plans. There are Free, Starter, Pro and Agency plans. The daily or monthly limits of each plan are stated on the pricing page. The Free plan is free of charge within the stated limits.
• Data credit. Paid data retrievals are measured in data credits. Your plan may include a certain credit allowance; you may also purchase a one-time credit package. The number of credits a query will spend is shown in the interface. Credit spent on a completed query is not added back; if a query returns no result because of an error on our side, we refund the credit spent.
• Payment method. You pay in one of two ways: bank or credit card, or cryptocurrency (USDT and TRX). Both are made through a payment processor; your card details are entered on the payment processor's secure page, and Kosto does not see or store them. For card payments, the payment provider (Paddle) acts as the merchant of record for the sale and handles payment, invoicing and tax collection; the provider's own terms also apply during payment, and in this transaction Kosto is the supplier of the software. The card option may not be enabled on every account; the methods that are available are shown on the checkout screen. For crypto payments, the amount, network and payment address are shown on the checkout screen. You must send the full amount on the network shown and to the address shown. How payments that are short, excess or sent on the wrong network are handled is set out in the refund policy; recovery of a payment sent to the wrong network or address is not guaranteed.
• Renewal. A subscription paid in crypto does not renew by itself and no automatic charge is made; we send you an email reminder before the period ends. A subscription paid by card renews automatically at the end of each period, until you cancel, from the same card at the plan price of that day; this is stated clearly on the payment screen before payment. You can turn off automatic renewal at any time from the “Plan and usage” section of your account page; the plan works until the end of the paid period and no further charge is made. Offers sold on a one-time basis (e.g. the founder year) do not renew even if purchased by card. At the end of the period, if you do not renew, a short grace period (3 days) is allowed; after that, your account reverts to the Free plan. Your data is not deleted for this reason; only your plan limits decrease.
• Plan change. When upgrading to a higher plan, the unused part of the previous period is deducted proportionally from the price of the new plan. A downgrade to a lower plan starts at the end of the current period.
• Annual payment. With annual payment, you pay for ten months instead of twelve. There is no lifetime package.
• Minimum payment amount. The amount of a payment cannot fall below 1 USD. If a discount, account credit or the remaining-time amount deducted on an upgrade would reduce the amount below 1 USD, the amount payable is 1 USD.
• Price change. Prices and limits may change. A change does not affect the period already paid for at that time; it applies from the following period.
• Taxes and network fees. Applicable taxes and network transaction fees are your responsibility; for card payments, tax is shown separately on the checkout screen as stated by the payment provider. Prices are shown in USD.

6. Acceptable use

The following are prohibited:

• Using the service or the API in an automated and bulk manner that exceeds rate limits; opening multiple accounts to exceed limits.
• Reselling the results of the service as a whole, or copying them in bulk in order to build a competing data product.
• Using the service as a tool to access, scan or attack systems on a local or private network.
• Publishing the results in a misleading manner with the aim of damaging the reputation of a person or organization.
• Transferring or sharing the account or API keys.
• Attempting to circumvent or disrupt the security, payment flow or infrastructure of the service; using it for any purpose contrary to the law.

7. Intellectual property

Kosto's software, scoring method, interface, name and visual identity belong to Ahmet Budak (Kosto). You are granted a limited, non-exclusive, non-transferable right to use the service for your own business for the duration of your plan. The domain lists and watchlists you enter belong to you; you grant us the right to process them in order to provide the service.

8. Third-party data and infrastructure providers

The Service draws on publicly available sources and on third-party data and infrastructure providers. Interruption, delay, change or error in these sources may affect the results. Where a source is temporarily unavailable, results may be incomplete or delayed; Kosto indicates this in the interface where possible. We do not guarantee the accuracy of data coming from third-party sources.

9. Service level

The Service is provided "as is" and "as available". Scheduled maintenance, interruptions and errors may occur. No commitment to uninterrupted operation is given; we try to keep interruptions to a minimum.

10. Limitation of liability

• Kosto's total liability to you arising out of or in connection with the Service or these terms is limited to the total amount you paid for the Service in the 12 months preceding the event giving rise to the damage. For users of the free plan, this limit is zero, to the extent permitted by mandatory law.
• We are not liable for indirect damages, loss of profit or revenue, loss of reputation, lost opportunities, damages arising from the purchase or sale of a domain name or link, or changes in rankings or traffic.
• For crypto payments, we accept no liability for losses arising from circumstances outside our control, such as network congestion, delay by the payment processor or the blockchain, or a transfer sent to the wrong network or address.
• The limits in this section do not apply in cases of intent and gross negligence, to liabilities that cannot be limited under Turkish law, or to the extent that they would remove a consumer's statutory rights.

11. Suspension and termination

• You may close your account at any time. Closing does not mean a refund of the paid period; refunds are made according to the conditions in the refund policy.
• If you breach Article 6, if we see a payment or security risk, or if a legal obligation arises, we may suspend or close the account with a warning or, if necessary, without a warning. For non-serious breaches, we try first to give a warning and an opportunity to remedy.
• What happens to your data after closure is set out in the privacy policy.
• We may close Free accounts that have gone unused indefinitely or for a long period, provided we give prior notice.

12. Changes to the terms

We may update these terms from time to time. We announce material changes by email or within the Service a reasonable time before they take effect. Your continued use of the Service after a change means that you accept the new terms; if you do not accept them, you may close your account. The "Last updated" date at the top of this page shows the current version.

13. Governing law and jurisdiction

The laws of the Republic of Türkiye apply to these terms. In disputes, for users who qualify as consumers, the consumer arbitration committees (Tüketici Hakem Heyetleri) and consumer courts are competent within the monetary limits set by legislation; for other disputes, the courts and enforcement offices of Akşehir (Konya) are competent. The rights of consumers resident in the European Union or the United Kingdom arising from the mandatory consumer protection provisions of their country of residence are reserved.

14. Miscellaneous

If any provision of the terms is held invalid, the other provisions remain valid. Our failure to exercise a right does not mean that we have waived that right. For the processing of personal data, see the Privacy, and for refunds and withdrawal, see the Refund Policy texts; they form part of these terms.
