Notice and Take Down Policy

Kumo respects your rights and expects that you respect the rights of others. In the unfortunate event that Kumo finds or is notified of unlawful files or content being distributed through it’s Service, we will follow the procedures described in this Notice and Take Down Policy. By using our website or file transfer service, you agree to be bound by our Notice and Take Down Policy below.

Report requirements

Any person or organization that makes a Report (“Notifier”) has the duty to ensure that it is correct and complete. Kumo should be able to verify that Reports following an investigation regarding a criminal offence have originated from an inspection or investigation service, or – in the case of a formal legal order – from the Public Prosecutor’s Office. A Report of any other nature than the foregoing should include at least the following information: Notifier’s contact details, name, function, organisation, address, email address); all information Kumo needs in order to evaluate the lawfulness of the disputed content, including its location (URL); motivation as to the unlawfulness of the content, or why it is in conflict with Kumo’s Terms of Service, NTD or Privacy Policy; motivation of the reason(s) why Kumo is the most appropriate intermediary to deal with the matter.


Notifier will provide Kumo with an explicit indemnity against 1) claims from the user who’s content is at dispute (“Content Provider”) relating to any actions Kumo has taken in relation to handling the Report, and 2) any claims from Notifier in relation to content send through our Service. Urgency Notifier might request Kumo to deal with the report as a matter of urgency. In that case, the Report should substantiate all reasons for urgency. Kumo determines at its own discretion whether the report should be dealt with as a matter of urgency on the basis of the foregoing explanation.


Kumo shall evaluate the Report and classify it into one of three categories: punishable content reported by an inspection or investigation service, or – in the case of a formal legal order – by the Public Prosecutor’s Office; unequivocally unlawful content and/or punishable content reported by other sources than the authorities listed under 1); and all other content, falling neither under category 1) or 2).


Kumo’s categorisation of the Report determines which measures are taken to address the Report. In the event that Kumo determines that the content concerned is unequivocally unlawful or punishable, in other words falls under the above mentioned categories 1) and 2), Kumo ensures that the content concerned is immediately removed; In the event that Kumo determines that the content concerned is not unequivocally unlawful or punishable, in other words falls under the above mentioned category 3), the content concerned shall not be removed. Kumo will inform Notifier accordingly; In the event that Kumo is not or unsufficiently able to judge whether the content concerned is unequivocally unlawful or punishable, Kumo will inform Content Provider about the Report with the request to (i) allow Kumo to remove the content or (ii) to contact Notifier. If Notifier and Content Provider are unable to reach an agreement, Notifier can make an official report to the police if a criminal offence might be concerned. If it concerns content that is alleged to be unlawful under civil law, Notifier can bring the dispute with Content Provider before a Swiss court of law. Should Content Provider be unwilling to sufficiently identify himself to Notifier, Kumo has the right to (i) provide Notifier with the Content Provider’s name, email address and IP-address or (ii) to remove the content concerned.


Categorisation and appropriate measures will preferably take place as soon as possible, yet ultimately 10 days after receiving the Report.

Due caution

In the events that content is to be removed, Kumo shall exercise due caution to ensure that no more than the necessary content, in regards of the Report, is removed.

Subscription and payment intermediary

By signing up for a Kumo Plus Account and providing us with Your payment information, You hereby agree to these payment terms and conditions. The subscription fee for a Kumo Plus Account is 120 USD ($120) excluding VAT, charged to the payment provider of Your choice. Your Kumo Plus Account will not expire after the first year, but will be renewed automatically. This means that You will be billed in advance on a recurring, periodic basis (“Billing Cycle”). Billing Cycles are annual. We will automatically charge You 14 days prior to the calendar day corresponding to the commencement of Your Kumo Plus subscription. You acknowledge that the amount billed each year may vary for reasons that may include but are not limited to: differing amounts due to promotional offers or changes in the amount of applicable sales tax; and You authorise Kumo to charge You for such varying amounts. To use our service and to store all this data, we ask a very reasonable subscription fee of 120 USD/EUR per year. We’ll automatically renew your account. We work with trusted payment intermediary Adyen (Adyen.com). Adyen supports credit cards, PayPal and local payment systems. Kumo notifies You when the (next) annual account fee is scheduled to be charged via the e-mail address You provided with Your Account. It is Your responsibility to have sufficient balance to enable the subscription fee to be charged. In the event that the subscription fee can, for any reason whatsoever, not be collected, Your Account will be terminated. You may cancel auto-renewal on Your Kumo Plus subscription at any time by emailing us (plus@Kumo.link) or by changing Your settings in Your "Billing information" page here, in which case Your subscription will continue until the end of that Billing Cycle before terminating and without any right to reimbursement of (part of) the subscription fee. Upon termination, Your Account, including Your personal data, address book and any Files stored for transfer, are directly, automatically and permanently deleted. You must cancel Your Kumo Plus Account before it renews each year in order to avoid billing of the next year's fees to You If You want to use a different payment method or if there is a change in Your payment information, You may set Your Account to be renewed manually instead. You can then adjust Your Account information during the renewal process. You are responsible for ensuring that all of Your Account information, including Your email address and all payment information is accurate and up to date at all times. If Your credit card expires or the payment information is otherwise invalid, the recurring payment attempt of Your Plus subscription will fail, which can lead to termination of Your Account. However, You will receive a notification e-mail about this failed attempt and You will be able to renew Your Plus Account manually. We’ll let you know in advance when your account is up for renewal. If you don’t have enough balance to pay for it, your subscription will expire. If you don’t want your account to be automatically renewed, tell us so in advance. We’ll then send you a couple of reminders at the end of the subscription to renew your account. If you snooze you lose. If you don’t renew your account or cancel it, there will be no more data.

Kumo Responsible Disclosure Policy

At Kumo we take great pride and care in designing our service in such a way that everyone can use it easily, safely and securely. Despite our efforts, we know that security vulnerabilities can never be fully prevented at all times. Security researchers and the internet community have an important role in keeping Kumo secure. For those who believe they have found a vulnerability in our service, we encourage them to act responsibly and report this vulnerability in accordance with this Responsible Disclosure Policy so we can work together to ensure the safety and security of our service and users. This policy explains how to report a vulnerability, what the process is and how we will respond to such reports. We’ve made an effort to make this policy as easy and clear as possible, but do let us know if there are things you don’t understand. You can contact us at secureforsure@Kumo.link. If you think you’ve found a vulnerability in our security, we appreciate it if you do the right thing and make a responsible disclosure to us first.


If you believe you have discovered a security vulnerability in the Kumo service, please send an email to secureforsure@Kumo.link with a thorough explanation of the (characteristics of the) vulnerability (Authentication/Authorisation, CSS, CSRF, XML, SQL, etc.) and with sufficient details, including a Proof-of-Concept, which system or systems are concerned and how we can reproduce your steps.

How soon will we respond?

Depending on the vulnerability, our support team will reply as quickly as possible, or at least within 24 hours. Your report will then be quickly routed to the person best able to evaluate and act on your report. Someone from our staff will contact you personally to understand what the vulnerability is and to learn how we can patch it. You will receive a digitally signed confirmation of receipt of your report and how to contact your designated case handler to discuss the next steps. We will keep you updated on the progress during the process.

Publishing the vulnerability

We do not publish information about specific vulnerabilities or reports we have received under this responsible disclosure policy. However, at your request, we can provide a personal reference on your request.

Recognition and remuneration

Anyone who is kind enough to report a significant vulnerability responsibly and follows the rules of this responsible disclosure policy, we will provide with Kumo memorabilia or a Kumo Plus account (with a value of $120). The reward may be based on the quality of the disclosure and nature of the vulnerability. If you prefer to make your report as John Doe (anonymously) or under a pseudonym, be our guest.

PGP public key

Please send us your report in an encrypted or digitally signed message.

What does not count as a vulnerability?

Although we appreciate your efforts, there are certain acts that do not count as a vulnerability that falls within the scope of this Responsible Disclosure Policy. This policy thus does not allow for: gaining access by ways of social engineering; creating your own back-door to gain access to the system. This could damage our service and create additional, unnecessary security risks; or DDoS or brute-force attacks.


Kumo will, within reason, hold blameless anyone who in good faith penetrates our site, and in the process of exploring or experimenting, extracts a small amount of sensitive data, as long as that person promptly notifies Kumo and destroys any data collected. If you follow the rules of this responsible disclosure policy and act in good faith, Kumo will not take legal action against you or ask law enforcement to start criminal investigations. Not acting in good faith includes, but is not limited to: providing any information with regard to the vulnerability to any third party without the consent of Kumo; misusing the vulnerability in any way; or copying, deleting or altering any of the Kumo related data you have gained access to. Legal action can be taken against disclosers of whom Kumo suspects that they did not act in good faith when penetrating the website or any related systems.
