These Terms of Service (Terms) govern access to and use of Helmly (Service), a web-based application for managing clients, activities, projects, tasks, and invoicing, provided by Michal Štefaňák, a company registered in Czechia, with registered address at Zelenecká Lhota 93, 507 23, Czechia and registration number 19882823 (we, us, our).
By creating an account or using the Service, you (you, User) agree to be bound by these Terms. If you do not agree, do not use the Service.
The Service is designed for use by a single individual user to manage their own clients, projects, tasks, activities, and invoices. It is not currently designed for use by teams or multiple simultaneous users under one account. We may introduce team or multi-user functionality in the future; any such functionality will be governed by these Terms as updated, or by additional terms presented to you at that time.
2.1. You must be at least 18 years old, or the age of legal majority in your jurisdiction, and have the legal capacity to enter into a binding contract to use the Service.
2.2. You must provide accurate, current, and complete information when registering, and keep it up to date.
2.3. You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. Notify us immediately of any unauthorized use.
2.4. One account is intended for use by one individual user. Sharing account credentials to provide access to multiple individuals is not permitted under these Terms unless and until we offer a team plan.
3.1. New accounts receive a free trial period of 14 days from the date of registration, during which the Service is provided without charge and without feature limitations. No payment method is collected or charged during the trial.
3.2. At the end of the trial period, continued use of the Service requires you to actively provide payment details and confirm a paid subscription. No contract to pay for the Service, and no charge, arises unless and until you take this step. If you do not subscribe, your access to the Service (or certain features, at our discretion) may be suspended or limited.
3.3. When you confirm a paid subscription, you will be asked to expressly request immediate access to the paid Service and to acknowledge that, once your subscription begins, you may lose any statutory right of withdrawal that would otherwise apply to that contract, to the extent permitted by applicable law. This confirmation is a condition of starting your subscription.
3.4. We may change the length or availability of the free trial for new registrations at any time, without affecting trials already in progress.
4.1. After the trial period, access to the Service requires payment of a recurring monthly subscription fee, as displayed on our pricing page at the time of purchase (“Subscription Fee”).
4.2. Subscription Fees are billed in advance on a monthly, recurring basis, until you cancel.
4.3. We may change our Subscription Fees. We will give you at least 30 days' notice of any price increase before it takes effect. Continued use of the Service after a price change takes effect constitutes acceptance of the new price. If you do not agree to a price change, you may cancel your subscription before it takes effect.
4.4. All fees are exclusive of applicable taxes (such as VAT) unless stated otherwise. Where required by law, applicable tax will be added to your invoice based on your location.
4.5. Payments are processed by third-party payment processors. You agree to provide accurate and current billing information.
5.1. You may evaluate the Service in full during the free trial at no cost, before any payment obligation arises. Because you actively request and confirm your subscription — including, where applicable, expressly requesting immediate access and acknowledging any resulting loss of a statutory withdrawal right as described in Section 3.3 — subscription payments are non-refundable, including for partial billing periods, unused time, or if you choose to stop using the Service before the end of a paid period.
5.2. This no-refund policy does not affect:
5.3. If you believe you are entitled to a refund under a mandatory legal right referenced in 5.2, contact us at contact@helmly.eu and we will assess your request in accordance with applicable law.
6.1. You may cancel your subscription at any time through your account settings or by contacting us. Cancellation takes effect at the end of the current billing period; you will retain access until then, and no further charges will be made.
6.2. We may suspend or terminate your account if: (a) you breach these Terms; (b) payment is not received when due; (c) we reasonably suspect fraudulent, abusive, or unlawful use; or (d) we discontinue the Service, subject to Section 11.
6.3. Upon termination, your right to access the Service ends. We may delete your account data after a reasonable retention period, as described further.
6.4. Upon Account Deletion Request. If you request the deletion of your account, we will initiate the deletion of your account credentials and User Content. However, we may retain certain data for up to 30 days following your request to allow for complete removal from our active databases and backup systems, or as required by law.
6.5. Upon Non-Payment or Subscription Expiration. If your paid subscription expires, is cancelled, or terminates due to non-payment, we will retain your User Content for a grace period of 60 days from the date of payment failure or cancellation. During this period your account is still active, but without full access. Following the expiration of this grace period, we reserve the right to permanently delete all associated User Content from our systems without further notice.
6.6. Statutory Retention Exceptions. Notwithstanding Sections 6.4 and 6.5, we may retain specific transactional, billing, or account data after account deletion or termination for up to 10 years (or the minimum period required by applicable tax, accounting, and anti-fraud laws in Czechia).
You agree not to:
We reserve the right to suspend accounts that violate this section.
8.1. You retain ownership of all data you input into the Service, including client information, projects, tasks, activities, and invoices (User Content).
8.2. You grant us a limited license to host, store, process, and display User Content solely as necessary to provide and improve the Service to you.
8.3. You are solely responsible for the accuracy, legality, and appropriateness of User Content, including any personal data of your clients that you upload. You represent that you have the necessary rights and legal basis to upload such data, including compliance with applicable data protection law (e.g., GDPR) with respect to your own clients' data.
8.4. You can export or request deletion of your data as described in our Privacy Policy.
The Service, including its software, design, branding, and underlying technology, is owned by us or our licensors and is protected by intellectual property laws. These Terms do not grant you any rights to our intellectual property except the limited right to use the Service as intended.
10.1. We aim to keep the Service available and reliable but do not guarantee uninterrupted or error-free operation. We may perform maintenance, updates, or changes to features from time to time.
10.2. We may add, modify, or remove features of the Service, including in connection with any future team/multi-user functionality, provided that such changes do not materially reduce the core functionality you are paying for without reasonable notice.
If we decide to permanently discontinue the Service, we will provide at least 30 days' advance notice via email or in-app notification, and you will not be charged for any period after discontinuation. Section 5 (No Refunds) still applies to periods already paid for and used prior to the discontinuation notice.
To the maximum extent permitted by applicable law, the Service is provided “as is” and “as available,” without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, or non-infringement. We do not warrant that the Service will be error-free, secure, or uninterrupted, or that it will meet your specific requirements. Nothing in this section limits any statutory rights that cannot be excluded under applicable law.
13.1. To the maximum extent permitted by applicable law, we shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, revenue, data, or business opportunities, arising out of or related to your use of the Service.
13.2. Our total aggregate liability for any claim arising out of or relating to these Terms or the Service shall not exceed the amount you paid us in the 12 months preceding the event giving rise to the claim.
13.3. Nothing in these Terms limits liability that cannot be limited or excluded under applicable law, including liability for death, personal injury caused by negligence, or fraud.
You agree to indemnify and hold us harmless from any claims, damages, liabilities, and expenses (including reasonable legal fees) arising from your breach of these Terms, your violation of applicable law, or your User Content, including any claims brought by your clients relating to their personal data.
Our collection and processing of personal data, including personal data you upload about your clients, is described in our Privacy Policy. By using the Service, you also agree to the terms of that Privacy Policy. As we are based in the EU, we process personal data in accordance with the General Data Protection Regulation (GDPR).
We may update these Terms from time to time. If we make material changes, we will notify you by email or in-app notice at least 14 days before the changes take effect. Continued use of the Service after the effective date constitutes acceptance of the updated Terms.
17.1. These Terms are governed by the laws of Czechia, without regard to its conflict of law principles.
17.2. Any dispute arising out of or relating to these Terms or the Service shall be subject to the exclusive jurisdiction of the courts of Czechia, except that if you are a consumer resident in the EU, you may also be entitled to bring proceedings in the courts of your country of residence under mandatory consumer protection rules, or relevant national alternative dispute resolution bodies.
18.1. Entire Agreement. These Terms, together with our Privacy Policy, constitute the entire agreement between you and us regarding the Service.
18.2. Severability. If any provision of these Terms is found unenforceable, the remaining provisions remain in full force.
18.3. No Waiver. Our failure to enforce any right or provision of these Terms is not a waiver of that right.
18.4. Assignment. You may not assign these Terms without our consent. We may assign these Terms in connection with a merger, acquisition, or sale of assets.
18.5. Contact. Questions about these Terms can be sent to contact@helmly.eu.
