Terms of Service — Version 2.0 — Effective 2026-07-19
In plain language: these Terms govern the Kelavon website, purchase process, view-only license-help tools, support channels, and any separately agreed services. Software use is also governed by the EULA. Kelavon Task Manager is a local desktop application, not a hosted service.
1. Scope and acceptance
These Terms apply when you browse the Website, request information, submit a support or contact form, purchase or evaluate the Software, manage a license, or order services. By doing so, you agree to these Terms to the extent permitted by applicable law.
2. Supplier identity
The Website and Software are operated and supplied by Denys Nalbat, trading as Kelavon, Mattackerstrasse 9, 8052 Zürich, Switzerland. Kelavon is a trading name and is not an incorporated GmbH or AG.
3. Relationship with the EULA
The EULA governs installation and use of the Software. These Terms govern the Website, transactions, support, and other services. If they conflict on Software-use rights, the EULA prevails; mandatory law always prevails.
4. Eligibility and authority
You must be at least 18 years old and legally capable of entering into the purchase and license agreement. If acting for an organisation, you represent that you are authorised to bind it.
4a. Business Customers and Consumers
Business Customer means a person or organisation purchasing primarily for trade, business, professional, governmental, regulatory, or organisational purposes.
Consumer means a natural person purchasing primarily for purposes outside their trade, business, or profession.
Both may purchase. Where these Terms or the EULA distinguish between them, the distinction reflects mandatory consumer law, which is never excluded. You are asked to declare your purchase type at checkout; entering an organisation name does not by itself remove Consumer protections where they apply as a matter of law.
4b. Territories, sanctions and export control
The Software is offered to eligible customers in countries supported by Stripe Managed Payments, subject to applicable law, sanctions, export controls, and payment-provider restrictions. It is not offered where its sale, purchase, export, import, licensing, or use would violate applicable law, sanctions, export controls, or restrictions imposed by the merchant of record or payment providers.
You represent that you are not located in, ordinarily resident in, or acting on behalf of a prohibited jurisdiction or sanctioned person, and that you will not export, transfer, or make the Software available contrary to applicable restrictions. Supported countries are determined by the merchant of record and may change without notice to Kelavon.
Self-service purchase covers software licenses and device-capacity add-ons only. Consulting, custom development, and technical support sold as a service are not available through this checkout and require a separate written arrangement.
5. Product description
Kelavon Task Manager is a Windows desktop task-management application. Customer Data is stored locally in Excel files controlled by the Customer. Kelavon does not host or synchronise that operational data unless a separately described feature is introduced later.
6. No account model
The App does not require a user account or password. Commercial licensing uses a license key and purchase email. The license-help site uses an email magic link to show available license and activation information; it does not release or transfer permanent seats. You are responsible for controlling access to the purchase email and license key.
7. Trial
A seven-day evaluation may be started in the App without providing an email address. It is device- or installation-gated and may use technical identifiers disclosed in the Privacy Policy. You may not bypass, reset, automate, or manipulate trial controls.
8. Orders and formation of contract
Product pages and quotes are invitations to order unless stated otherwise. The sales contract is formed as specified in the checkout and merchant-of-record terms, usually when payment is accepted and the order confirmation is issued. Obvious pricing or description errors will be corrected promptly and fairly.
9. Merchant of record and payment
Payments are processed through Stripe Managed Payments. The merchant of record is identified at checkout and on the receipt. That party may process payment, calculate and remit indirect taxes, issue transaction documents, and handle assigned fraud, refund, and dispute functions under its terms. Kelavon remains responsible for the Software and obligations not assumed by the merchant of record.
10. Prices and taxes
Current self-service prices and included seat capacities are shown on the pricing and order-review pages. Prices are shown in Swiss francs unless another currency is displayed at checkout.
Applicable VAT, GST, sales tax, and similar indirect taxes are calculated according to the customer's location and displayed before payment. For purchases processed through Stripe Managed Payments, Stripe or its designated merchant-of-record entity calculates, collects, and remits applicable indirect taxes for the customer transaction. The final amount payable is shown before the order is submitted. Manifest errors may be corrected subject to mandatory law.
11. Delivery
Delivery normally occurs electronically through a download link, license key, purchase email, or instructions. You must provide a usable email address and retain the order records. Kelavon commits to make initial activation available for 90 days from purchase. After that period, activation may remain available on a best-effort basis but is not guaranteed, including if the licensing service has been discontinued.
12. License model
A purchase grants a perpetual license for the purchased Major Version, subject to the EULA and purchased permanent-seat capacity. It is not a subscription and does not include future Major Versions. Updates for the purchased Major Version are included only if and when Kelavon releases them; no update or defect correction is promised.
13. Activation and capacity
Each genuinely new device requires an online activation and permanently consumes one seat. The request may include the license key, purchase email, App version, installation ID, and normalized board/disk/CPU identifiers as described in the Privacy Policy and License Activation Policy. The licensing service compares immutable salted anchors; qualifying same-device re-activation does not consume another seat. Requests beyond capacity may be refused.
14. Permanent seats and no deactivation
A purchased seat is permanently consumed when a new activation anchor is created. There is no self-service deactivation, release, or automatic device transfer. Replacing the whole computer or changing enough binding components may require a new seat. Customers may purchase expansion capacity or contact support, but no seat reset is promised.
15. Permitted website use
You may use the Website for lawful evaluation, purchase, support, license management, and information. You may link to public pages fairly, provided you do not misrepresent endorsement or frame the Website deceptively.
16. Prohibited use (Acceptable Use)
- Violating law, third-party rights, export controls, sanctions, or professional obligations.
- Probing, overloading, disrupting, abusively scraping, or circumventing Website or licensing security.
- Submitting malware, malicious files, false purchase data, fraudulent disputes, or automated activation attempts.
- Forging keys, exceeding purchased permanent-seat capacity through circumvention, resetting trials, suppressing or falsifying device-component collection, intercepting or altering activation traffic, sharing keys publicly, or copying installation IDs, entitlements, activation data, profiles, or virtual-machine images to evade binding.
- Reverse engineering or bypassing license controls except where mandatory law expressly permits.
- Using the Website to transmit unlawful, threatening, abusive, discriminatory, or infringing content.
- Misrepresenting affiliation with Kelavon or reselling licenses without written permission.
Enforcement may include blocking future activations, rejecting requests, applying rate limits, preserving proportionate evidence, or reporting unlawful conduct. Enforcement cannot remotely disable already activated offline installations and does not create self-service seat release. Report suspected abuse to support@kelavon.com.
17. Customer responsibilities
You are responsible for selecting the Software, system compatibility, lawful use, user training, access controls, backups, retention, validation, and the accuracy and integrity of Customer Data. The Software does not replace professional judgment or required regulated procedures.
18. Regulated environments
Use in pharmaceutical, quality, regulatory, clinical, or other controlled environments does not make Kelavon the Customer's regulated service provider, quality unit, data controller for Customer Data, or validation adviser unless expressly agreed in writing. The Customer must assess fitness and complete any required validation.
19. Intellectual property
The Website, Software, Documentation, trademarks, design, and code are owned by Kelavon or its licensors and protected by law. No ownership is transferred. Feedback may be used without restriction or compensation, provided Kelavon does not publicly identify the submitter without permission.
20. Third-party components and links
The Software or Website may include or link to third-party components governed by their own licenses and policies. Kelavon is not responsible for independent third-party services, but will provide legally required notices for bundled open-source components.
21. Updates and changes
Kelavon may, at its discretion, issue Maintenance Updates or change the Website. Updates for a purchased Major Version are included if and when released, but Kelavon does not undertake to release an update or correct a particular defect. An already purchased perpetual Major-Version license will not be silently converted into a subscription.
22. Support
Standard support is email-based and governed by the Support Policy. Unless separately agreed, it does not include custom development, phone/chat support, guaranteed response or resolution times, a service-level agreement, or future Major-Version upgrades.
23. Custom work
Custom development, consulting, migration, training, validation assistance, or other professional services require a separate written scope, price, timeline, deliverables, acceptance process, and intellectual-property terms. A feature request is not an accepted commitment.
24. Refunds and disputes
Refunds are governed by the Refund Policy, checkout terms, and mandatory law. A refund or charge reversal may block future activations. Existing offline installations cannot ordinarily be remotely revoked, but the legal license may terminate and continued use may be unauthorised.
25. Privacy and cookies
Personal data is processed under the Privacy Policy. Cookies and similar technologies are described in the Cookie Policy. The cookie disclosures and consent mechanism will be updated before any non-essential analytics, advertising, embedded tracking, or session-recording technology is enabled.
26. Confidentiality of submitted material
Do not submit unnecessary confidential or regulated information. Kelavon will use reasonable care with support materials but does not accept special confidentiality, data-processing, or security obligations unless separately agreed in writing.
27. Security
No system is completely secure. You must protect your device, files, email, magic links, and license key. Notify Kelavon promptly of suspected compromise. Never send card numbers, passwords, private keys, or recovery phrases through support.
28. Availability
The Website, downloads, support, and licensing service may be unavailable temporarily. Kelavon commits to initial activation availability for 90 days from purchase; after that, activation is best-effort and not guaranteed. Already activated installations remain offline-capable. Unless separately agreed, no other uptime, recovery, or SLA commitment is provided.
29. Suspension and restriction
Kelavon may proportionately block new activations, restrict Website access, or decline abusive support when reasonably necessary for security, fraud prevention, legal compliance, or material breach. This does not create a technical ability to disable an offline activated installation.
30. Disclaimers
To the maximum extent permitted by law, the Website and Software are provided on an "as available" basis with the express warranties stated in the EULA or mandatory law. Kelavon does not warrant regulatory approval, uninterrupted operation, error-free output, or suitability for every workflow.
31. Limitation of liability
Business Customers. To the maximum extent permitted by law, the aggregate liability of Kelavon arising out of or in connection with these Terms, the EULA, the Website, or the Software is limited to the amounts actually paid for the affected license and related device-capacity add-ons.
To the extent legally permitted, Kelavon is not liable to Business Customers for lost profits or revenue, loss or corruption of data, business interruption, loss of anticipated savings, loss of regulatory submissions or records, or indirect, consequential, exemplary, or punitive damages.
These limitations and exclusions do not apply to fraud, wilful misconduct, gross negligence, death or personal injury where liability cannot be excluded, or any other liability that applicable law does not permit to be limited or excluded.
Consumers. Nothing in these Terms limits statutory remedies or liabilities that cannot lawfully be excluded or limited. The Business Customer cap above does not apply to a Consumer where mandatory law provides otherwise.
32. Indemnity for unlawful use
For Business Customers only and to the extent permitted by law, the Customer is responsible for third-party claims caused by its unlawful Customer Data, unauthorised use, or breach of third-party rights. Kelavon will notify the Customer of any such claim without undue delay, will not settle it without the Customer's consent (not to be unreasonably withheld), and will allow the Customer to participate in its defence. This clause does not apply to Consumers.
33. Force majeure
Neither party is liable for delay caused by events beyond reasonable control, except payment obligations already due and obligations that cannot lawfully be excused. The affected party should mitigate and communicate where practicable.
34. Assignment
The Customer may not transfer the contract or license except as allowed by the EULA or with written consent. Kelavon may assign the business and related contracts to a successor, subject to applicable law and appropriate notice.
35. Governing law and disputes
These Terms and the EULA are governed by the substantive laws of Switzerland, excluding its conflict-of-law rules and the United Nations Convention on Contracts for the International Sale of Goods.
For Business Customers, the courts having jurisdiction at the registered business location of Denys Nalbat, trading as Kelavon, in Zürich, Switzerland, have exclusive jurisdiction.
For Consumers, this choice does not deprive the Consumer of mandatory protections or jurisdiction rights available under the law of the Consumer's habitual residence. A Consumer may bring proceedings in any court available under mandatory applicable law.
36. General provisions
If a provision is invalid, the remainder continues to the extent lawful. Failure to enforce is not a waiver. Headings are for convenience. These Terms, the EULA, order documents, and incorporated policies form the agreement, subject to mandatory law.
37. Changes and versioning
The version and effective date are shown at the top of this page. Material changes will be announced appropriately and prior versions preserved. Changes do not retroactively remove acquired rights unless lawfully agreed.
