We shall not be liable to you or to any third-party for any modification, suspension, or discontinuance of access to the Website. Certain products or services may be available exclusively online through the Website. These products or services may have limited quantities and are subject to return or exchange only according to our Shipping and Returns Policies.
Prices for our products are subject to change without notice. All descriptions of products/services or product/service pricing are subject to change at any time without notice, at our sole discretion. We reserve the right to limit the sales of our products and services to any person, geographic region, or jurisdiction. We may exercise this right on a case-by-case basis.

7. Payment
All charges are in United States Dollars (USD). We accept all major credit and debit cards and digital wallet platforms.
When placing an order online, you will need:
- The address the card’s statement is sent to (billing address);
- The card number and expiration date; and
- The 3 or 4 digit code found only on the card (CVV2 code).
By submitting credit card information or other payment information, you represent and agree that: (i) you are fully entitled to use that card or account; (ii) all payment information provided is complete and accurate; (iii) you will be responsible for any credit card fees; and (iv) that sufficient funds exist to pay us the amount(s) due.
We and our third-party payment service providers may request, and we may receive, updated credit card information from your credit card issuer, such as updated card numbers and expiration date information when your credit card has expired. If such updated information is provided to us and our third-party payment service providers, we will update your account information accordingly. Your credit card issuer may give you the right to opt-out of providing vendors and third-party payment service providers with your updated credit card information. If you wish to opt-out of your credit card’s updating service, you should contact your credit card issuer.
We are not responsible for any fees or charges that your bank or credit card issuer may apply. If your bank or credit card issuer reverses a charge to your credit card, we may bill you directly and seek payment by another method including a mailed statement.
8. Order Placement and Acceptance
Your electronic order confirmation, or any form of confirmation, does not signify our acceptance of your order. We reserve the right to accept or deny shipment to anyone for any reason. In the event we deny your order, you will receive a refund to your original form of payment. You understand and agree that we will not be liable for any losses or damages that may result from our refusal to provide you any service or product. We reserve the right to require additional information before processing any order. Unauthorized returns will not be eligible for a refund.
We reserve the right to refuse or cancel any order placed with us. This may include orders under the same customer account, payment method, billing address, or shipping address. If your order is canceled or modified, we will attempt to contact you using the email or phone number provided.
Once your order has been placed and processed, it cannot be edited or canceled unless approved by our team under exceptional circumstances.
By placing an order on this website, you accept full and unconditional responsibility for the transaction. This includes all orders made using your device, account, or payment method—regardless of who completes the transaction. We are not liable for purchases made by unauthorized users (e.g., children, other household members, or anyone else with access to your device or card) unless proven to be due to a fault on our part. It is your responsibility to ensure that all payment, shipping, and contact information entered during checkout is accurate and secure. Once submitted, all order information is considered final. If your child or another individual uses your card or device without permission, the liability remains with you as the account or cardholder.
For more information, please review our Return & Refund Policy.

Orders typically arrive within 4-6 business days, depending on location. Delivery time for international orders varies based on location.
Accurate shipping address and phone number are required. We are not responsible for late shipments/missing shipments if you enter incorrect shipping address information. If you discover that you have made a mistake with your order after it has been submitted, please contact customer support immediately by email at info@calmara.com. You must contact us as soon as possible in order to modify or cancel your pending order. However, we attempt to ship quickly, so we cannot guarantee that we will be able to amend your order in accordance with your instructions.
Customers will receive tracking information via email once their order has been shipped. We are not liable for shipping delays caused by incorrect addresses or courier delays.
For additional information about Calmara’s shipping practices, including limitations on the availability of free shipping, please visit the Shipping Details page on our Website.

12. Social Media
This section applies to everyone who interacts with our social media presence, including comment sections, feeds, and other elements of social media presence viewable on Facebook, Instagram, YouTube, Pinterest, Twitter, Google+, LinkedIn, or any of the many other available external third-party social media platforms we may utilize (“Social Media Presence”).
Social media platforms are places of public information exchange, and you should have no expectation of privacy when using them. Specifically, neither these Terms nor our Privacy Statement apply to our Social Media Presence. The sites and platforms that host our Social Media Presence are not controlled by us and therefore have their own privacy policies and terms of use. The comments and opinions expressed by users on social media are theirs alone and do not reflect the opinions of Calmara. Comments that some would consider inappropriate or offensive may appear on our Social Media Presence and may remain there until they have been identified by us or called to our attention and we are able to work through the necessary procedures and technical processes to have them removed. If you see an offensive or inappropriate post or comment on our Social Media Presence, you should report it to the operator of the applicable site or platform using the procedures they have established for that purpose.
13. Disclaimer of Warranties
Except where otherwise inapplicable or prohibited by law, this Website and all products and services provided are provided on an “as is”, “as available” basis without warranties of any kind, either express or implied, including but not limited to warranties of title or implied warranties of merchantability or fitness for a particular purpose. We make no, and expressly disclaim any and all, representations and warranties as to the reliability, timeliness, quality, suitability, availability, accuracy, and/or completeness of any information on this Website. We do not represent or warrant, and expressly disclaim that: (A) our products or services will meet your requirements or expectations, (B) the quality of any products, services, information, or other material purchased or obtained by you through the Website will meet your requirements or expectations, or (C) the Website or the server(s) that make the Website available are free of viruses or other harmful components. All conditions, representations and warranties, whether express, implied, statutory or otherwise, including, without limitation, any implied warranty of merchantability, fitness for a particular purpose, or non-infringement of third-party rights, are hereby disclaimed to the maximum extent permitted by applicable law.
We strive to display the colors and images of our products as accurately as possible. We cannot guarantee your device’s screen will display them correctly.
We do not guarantee uninterrupted, timely, secure, or error-free service. You agree that we may remove or suspend the service at any time without notice.
14. Disclaimer of Liabilities
Except where otherwise inapplicable or prohibited by law, including under applicable US federal and state consumer protection laws, in no event shall Calmara or any of its officers, directors, shareholders, employees, independent contractors, and/or agents be liable for any indirect, special, incidental, exemplary, consequential, punitive, or any other damages, fees, costs or claims arising from or related to this Agreement, the Privacy Policy, the products or services, or your or a third-party’s use or attempted use of the Website or any product or service, regardless of whether Calmara has had notice of the possibility of such damages, fees, costs, or claims. This includes, without limitation, any loss of use, loss of profits, loss of data, loss of goodwill, cost of procurement of substitute services or products, or any other indirect, special, incidental, punitive, consequential, or other damages. This applies regardless of the manner in which damages are allegedly caused, and on any theory of liability, whether for breach of contract, tort (including negligence and strict liability), warranty, or otherwise.
Nothing in these Terms shall limit or exclude our liability for death or personal injury resulting from our negligence, for fraud or fraudulent misrepresentation, or for any liability that cannot be limited or excluded under applicable US law. Furthermore, Calmara offers a 2-year warranty on all products, covering manufacturing defects and faults in materials or workmanship from the date of delivery, in addition to your statutory rights under applicable US consumer law.
If, notwithstanding the limitations of liability set forth above, Calmara is found liable under any theory (excluding claims under the 2-year warranty or statutory rights), Calmara’s liability and your exclusive remedy will be limited to USD $500.00. This limitation of liability shall apply for all claims, regardless of whether Calmara was aware of or advised in advance of the possibility of damages or such claims. Some jurisdictions do not allow the exclusion of certain warranties or liabilities, so some of the above exclusions may not apply to you and you may have additional rights under US law.
To the fullest extent permitted by law, Calmara shall not be liable for any direct, indirect, incidental, punitive, or consequential damages, including lost profits, lost data, or loss of use.
15. Indemnification
To the fullest extent permitted by law, you agree to indemnify, defend, and hold harmless Calmara, its parent, subsidiaries, predecessors, successors and affiliates, and their respective partners, officers, directors, agents, representatives, contractors, licensors, service providers, subcontractors, suppliers, interns, and employees, from and against any and all claims, actions, losses, liabilities, damages, expenses, demands and costs of any kind, including, but not limited to, reasonable attorneys’ fees, arising out of, resulting from, or in any way connected with or related to (1) your use of the Website; (2) your breach of these Terms, the documents they incorporate by reference, or the Agreement; (3) your breach of any representations or warranties in this Agreement; or (4) your violation of any law or the rights of a third party.
