Kelssira Terms of Service
Last updated: 21 September 2026. Draft pending legal review.
This document is a draft pending legal review.
1. Acceptance of these terms
These Terms of Service govern the use of the website kelssira.com, the applications and the services offered by Kelssira, the trade name of Cancor LLC, a limited liability company registered in the state of Florida, United States ("Kelssira", "we", "us").
By creating an account, purchasing a subscription, downloading or using any of our applications, or engaging any of our services, you accept these terms. If you do not agree with them, do not use our services.
If you use our services on behalf of a company or other organisation, you represent that you have authority to bind it to these terms, and "you" will refer to that organisation.
2. Our services
Kelssira offers four kinds of services:
- Subscription applications: ready-to-use software, available for several platforms, accessed through a monthly or annual subscription.
- Custom development: building applications or websites for a specific client under a separate project agreement.
- Technical support: assistance with the applications we develop.
- Domain, website and email management: administering those resources on the client's behalf under a separate agreement.
Sections 3 to 8 apply mainly to subscription applications. Section 9 applies to custom and management services. The remaining sections apply to all services.
3. User account
To use our subscription applications you need to create an account with a valid email address. You must provide accurate information and keep it up to date.
You are responsible for keeping your password confidential and for all activity carried out from your account. You must notify us immediately at [email protected] if you suspect unauthorised use.
You must be at least sixteen years old to create an account. Our services are aimed at professionals and businesses.
4. Subscriptions, free trial and pricing
Each application states, on its page on our website or on its store listing, the monthly and annual subscription price, the length of the free trial if any, and the features included.
During the free trial you may use the application at no cost. When the trial ends, access continues only if you purchase a paid subscription. We will not charge you automatically at the end of the trial unless you have registered a payment method and expressly agreed to convert to a paid subscription.
Prices are stated in US dollars unless another currency is indicated. Applicable taxes are added where the law requires. We may change prices; any change will be communicated at least thirty days in advance and will apply from the next renewal period.
5. Payments and automatic renewal
Subscriptions purchased through our website are charged by Stripe, our payment provider. We do not store card details.
Subscriptions renew automatically at the end of each monthly or annual period, for an equal period and at the then-current price, until you cancel. Before each annual renewal we will send you a reminder by email.
If a charge fails, we will retry it and notify you. If payment is not completed, we will suspend access to the application. If the subscription remains unpaid for ninety days, we may close the account and delete the associated data in accordance with our Privacy Policy.
Subscriptions purchased inside an application distributed through the Microsoft Store, Google Play or the App Store are charged, renewed and cancelled through that store under its terms. In those cases billing, cancellation and any refunds are handled by the store, not by Kelssira.
6. Cancellation and refunds
You may cancel your subscription at any time from your account or by writing to [email protected]. Cancellation takes effect at the end of the period already paid, during which you keep access.
Periods already paid are non-refundable, in whole or in part, unless the law applicable in your country or state requires otherwise, or we choose to grant a refund at our discretion. We provide a free trial precisely so you can evaluate the application before paying.
If you are a consumer resident in the European Union or the United Kingdom, you may have a right to withdraw from the purchase within fourteen days; by starting to use the digital service within that period, you agree that the right of withdrawal is lost to the extent permitted by law.
7. Licence and restrictions
While your subscription is active we grant you a limited, non-exclusive, non-transferable and revocable licence to install and use the application on the devices stated in the product listing, for your own professional or business purposes.
You may not: copy, modify, decompile or reverse-engineer the application; resell, rent or sublicense it; circumvent its licensing or security mechanisms; use it for unlawful purposes; or use it to build a competing product.
All software, designs, trademarks and content are the property of Cancor LLC or its licensors. These terms transfer no ownership rights to you.
8. Your data and content
You retain ownership of all information you enter into our applications, including your customers' data. You grant us only the permission needed to store, process and back it up in order to provide the service.
You are responsible for the lawfulness of that data and for having the authorisations needed to enter it, especially where it includes third-party information.
We make regular backups, but we recommend that you export your data regularly. After cancellation you may request an export of your data for thirty days; after the period stated in the Privacy Policy, it will be deleted.
9. Custom development and management services
Custom development projects and domain, website and email management services are governed by a separate written agreement for each client, setting out scope, timeline, price, payment terms and ownership of deliverables. In case of conflict between that agreement and these terms, the agreement prevails.
Unless the agreement states otherwise: domains and email accounts are registered in the client's name, and the client is their owner; the client is responsible for paying renewals on time, and failure to do so may result in loss of the domain or accounts; and Kelssira retains rights over the tools, libraries and generic components it reuses across projects, granting the client a licence to use them within their project.
10. Technical support and availability
Technical support is provided by email at [email protected] for the applications and services we develop. We do not guarantee specific response times unless agreed in writing.
We work to keep our services continuously available, but interruptions may occur due to maintenance, updates, provider failures or causes beyond our control. We do not guarantee uninterrupted availability.
We may release updates that fix errors, improve security or add features. Some updates may be required to continue using the application. We may also withdraw features or entire applications with at least sixty days' notice; if we withdraw an application with active subscriptions, we will refund the unused portion pro rata.
11. Disclaimer of warranties
Our services are provided "as is" and "as available". To the fullest extent permitted by law, we disclaim all express or implied warranties, including those of merchantability, fitness for a particular purpose and non-infringement. We do not warrant that the software is error-free or that it will meet all your needs.
You are responsible for verifying that the application is suitable for your activity, for complying with the legal obligations of your profession or business, and for keeping copies of your information.
12. Limitation of liability
To the fullest extent permitted by law, Cancor LLC shall not be liable for indirect, incidental, special, consequential or punitive damages, or for loss of profits, revenue, data or goodwill, arising from the use of or inability to use our services.
Our total liability for any claim relating to a service shall not exceed the amount you paid us for that service in the twelve months preceding the event giving rise to the claim.
Some jurisdictions do not allow certain limitations of liability; in those cases the limitations apply to the fullest extent permitted.
13. Indemnity
You agree to hold Cancor LLC harmless from third-party claims arising from your use of the services in breach of these terms or the law, or from the data you enter into our applications.
14. Suspension and termination
We may suspend or terminate your access if you breach these terms, if your use endangers the security of the service or other users, or if the law requires us to. Where reasonable, we will notify you first and give you an opportunity to remedy the breach.
You may cancel at any time under section 6. Sections 7, 8, 11, 12, 13, 15 and 16 survive termination.
15. Governing law and disputes
These terms are governed by the laws of the state of Florida, United States, without regard to its conflict-of-law rules.
Before starting any legal action, we ask that you write to us at [email protected] to try to resolve the dispute in good faith for at least thirty days.
Any dispute not resolved in that way shall be submitted to the state or federal courts located in Broward County, Florida, to whose jurisdiction you submit, except where consumer protection law in your place of residence grants you non-waivable rights providing otherwise.
16. General provisions
We may amend these terms. We will publish the current version on kelssira.com with the date of the last update and, if the changes are significant, notify you by email at least thirty days in advance. If you continue using the services after that date, you accept the new terms; if you do not agree, you may cancel.
If any provision is held invalid, the remaining provisions remain in force. Our failure to exercise a right does not waive it. You may not assign these terms without our consent; we may assign them to an entity that continues our business.
These terms, together with the Privacy Policy and, where applicable, the relevant project agreement, constitute the entire agreement between you and Cancor LLC.
In case of any discrepancy between the Spanish and English versions of these terms, the English version prevails.
