Terms of Service

These Terms of Service (“Terms”) govern your access to and use of the websites, products, and services operated by Xernu (“Xernu”, “we”, “us”, or “our”), a technology company incorporated in Nigeria (FCT, Abuja).

By creating an account or using any Xernu product, you agree to be bound by these Terms. If you do not agree, do not use our services.

These Terms apply to all Xernu products, including Calynote, ADHDmate, Uno-SAP, and any future products under the Xernu umbrella.

You must be at least 13 years old to use our services. By agreeing to these Terms, you represent that you meet this requirement.

If you are using our services on behalf of a company or organisation, you represent that you have the authority to bind that entity to these Terms.

• Provide accurate and complete information when registering

Our services allow you to create, upload, and store content (“User Content”). You retain ownership of your User Content.

By using our services, you grant Xernu a limited, non-exclusive, royalty-free licence to store, process, and display your User Content solely as necessary to provide the services to you.

You are solely responsible for your User Content. You represent that you have all necessary rights to the content you submit, and that it does not violate any third-party rights or applicable law.

We do not claim ownership of your content and will not use it for any purpose beyond operating and improving the service.

Some of our products offer paid subscription plans. By subscribing, you agree to pay the applicable fees as described at the time of purchase.

• Subscriptions are billed on a recurring basis (monthly or annually, as selected)
• You authorise us to charge your payment method on each renewal date
• All fees are stated inclusive or exclusive of applicable taxes, as noted at checkout
• Payments are processed securely by our payment provider (Paystack); we do not store card details

Cancellation

You may cancel your subscription at any time from your account settings. Cancellation takes effect at the end of the current billing period. We do not provide refunds for unused time in a billing period unless required by law.

Price changes

We reserve the right to change our pricing. We will give you at least 30 days’ notice of any price change before it takes effect.

We may offer free tiers or beta access to our products. Free and beta services are provided “as is” and may be modified, limited, or discontinued at any time without notice.

We reserve the right to convert free features to paid features with reasonable notice.

Xernu and its licensors own all rights, title, and interest in and to the services, including all software, design, trademarks, logos, and content created by us. Nothing in these Terms transfers any of these rights to you.

You may not use our trademarks, logos, or brand assets without our prior written consent.

Our services may integrate with or link to third-party services (such as Google for authentication). Your use of those services is subject to the third party’s own terms and privacy policies. We are not responsible for the content or practices of third-party services.

We aim to keep our services available and reliable, but we do not guarantee uninterrupted access. We may carry out maintenance, updates, or changes at any time, which may temporarily affect availability. We will try to give advance notice of planned downtime where possible.

Our services are provided “as is” and “as available” without warranties of any kind, either express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, or non-infringement.

We do not warrant that the services will be error-free, secure, or continuously available.

To the fullest extent permitted by applicable law, Xernu shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including loss of data, loss of profits, or loss of business, arising out of or in connection with your use of our services.

Our total liability to you for any claim arising under these Terms shall not exceed the greater of (a) the total fees you paid to us in the 12 months preceding the claim, or (b) £100.

Nothing in these Terms excludes or limits our liability for death or personal injury caused by our negligence, fraud, or any other liability that cannot be excluded by English law.

You agree to indemnify and hold harmless Xernu and its officers, employees, and agents from any claims, damages, losses, or expenses (including legal fees) arising from your use of our services, your User Content, or your violation of these Terms.

You may close your account at any time by contacting us at hello@xernu.com or through your account settings.

We may suspend or terminate your access to our services at any time, with or without notice, if we believe you have violated these Terms, or for any other reason at our discretion. On termination, your right to use the services ceases immediately.

Sections that by their nature should survive termination (including ownership, disclaimers, limitation of liability, and dispute resolution) will continue to apply.

These Terms are governed by the laws of the Federal Republic of Nigeria. Any disputes arising from these Terms or your use of our services shall be subject to the exclusive jurisdiction of the courts of the Federal Capital Territory, Abuja, Nigeria.

Before pursuing formal legal action, we encourage you to contact us at hello@xernu.com so we can try to resolve the issue informally.

We may update these Terms from time to time. When we do, we will update the “Last updated” date at the top of this page. For material changes, we will notify you by email or via an in-product notice at least 14 days before the changes take effect.

Continued use of our services after changes take effect constitutes your acceptance of the updated Terms.
