By creating an account or using Reef Analysis, you agree to these Terms & Conditions. Please read them carefully. Questions? Email hello@reefanalysis.com.
Reef Analysis is a trading name of Ark Technology Ltd, registered in England & Wales (No. 11538549). References to "we", "us" or "our" mean Ark Technology Ltd. References to "you" or "your" mean the person or entity accessing or using the service.
Reef Analysis provides tools for saltwater reef aquarium hobbyists to upload and analyse ICP water chemistry test results, log home test kit readings, monitor live sensor data from connected devices (Apex Fusion, Alkatronic, Mastertronic, KH Guardian, KH Manager, AquaWiz), and use optional analysis and dosing-calculation modules including Reef Moonshiners (assessment, classic calculator, dosing buddy, product comparison) and Reef Log (event tracking). The service is provided for informational and organisational purposes only.
Important: Reef Analysis is not a substitute for professional aquatic or veterinary advice. Reference ranges, dosing calculations, product recommendations, and any other figures displayed within the application — including in the Reef Moonshiners module — are indicative only, may be inaccurate, and may be based on community-sourced or third-party methodologies that we do not control. You remain solely responsible for all decisions relating to your aquarium, livestock, additives, and dosing, including verifying any calculation before acting on it. We accept no liability for harm to livestock, coral, equipment, or property arising from reliance on data, recommendations, or calculations displayed in the application.
You agree not to:
The service integrates with third-party platforms including ReefZlements, ATI, Triton, Fauna Marin, Oceamo, Tropic Marin, Modern Reef, Apex Fusion, Alkatronic, Mastertronic, KH Guardian, KH Manager, and AquaWiz. The Reef Moonshiners module references and applies methodologies, target ranges, and product information developed by the Reef Moonshiners community; we are not affiliated with or endorsed by Reef Moonshiners or any of the device or laboratory brands listed above, and we are not responsible for the accuracy, completeness, or current applicability of any data, methodology, or recommendation supplied or referenced by these third parties. By connecting these services you confirm you have the right to do so under their respective terms of service.
When you provide credentials for third-party devices (e.g. Apex Fusion, Alkatronic, Mastertronic, KH Guardian, KH Manager, AquaWiz), you authorise us to access those platforms on your behalf solely to fetch and store your data within Reef Analysis. Credentials are stored encrypted and are never shared with third parties beyond what is necessary to operate this feature.
All intellectual property rights in the Reef Analysis application, including its design, code, and content, are owned by or licensed to Ark Technology Ltd. Nothing in these terms grants you any rights in that intellectual property other than the limited right to use the service as described here.
You retain ownership of all data you upload or enter into the service. By uploading data you grant us a limited licence to store and process it solely for the purpose of providing the service to you.
We aim to keep the service available at all times but do not guarantee uninterrupted access. We may carry out maintenance, updates, or changes at any time without notice. We reserve the right to modify or discontinue any part of the service at our discretion.
Consumers — your statutory rights are preserved. If you are a consumer (using the service wholly or mainly outside of any trade, business, craft or profession), nothing in these terms excludes or limits the protections you have under the Consumer Rights Act 2015 or any other consumer-protection statute, including the right that the service be supplied with reasonable care and skill (s.49 CRA 2015) and any rights you have in respect of digital content (Chapter 3, CRA 2015). This section operates subject to those statutory rights.
So far as permitted by law (and subject to Section 9 below), the service is provided "as is" and "as available". We do not give any warranty, condition or other term that the service will be uninterrupted, error-free, secure, or fit for any particular purpose, and we do not warrant that data displayed will be accurate, complete, or current. Third-party data shown within the service (including ICP-lab results, sensor readings, dosing methodologies, and product recommendations) originates with third parties and we do not warrant or guarantee it.
Commercial / business users. If you use the service in the course of a business (which you confirmed by selecting "Commercial" at registration, or otherwise), all conditions, warranties and other terms implied by statute, common law or otherwise are excluded to the maximum extent permitted by law. The Consumer Rights Act 2015 does not apply between us.
Nothing in these terms limits or excludes our liability for: (a) death or personal injury caused by our negligence; (b) fraud or fraudulent misrepresentation; (c) any breach of the terms implied by sections 49 to 52 of the Consumer Rights Act 2015 (services) where you are a consumer; or (d) any other liability which cannot lawfully be excluded or limited under English law. The remainder of this Section 9 takes effect subject to that carve-out.
Subject to the above, and to the fullest extent permitted by law, Ark Technology Ltd shall not be liable for any indirect, incidental, special, consequential, or punitive loss; loss of profit; loss of revenue; loss of business, goodwill or anticipated savings; loss of, corruption of, or inability to access data; or loss of, harm to, or death of livestock or coral; damage to aquarium equipment, water chemistry, ornaments, or other property — arising out of or in connection with your use of the service, even if we have been advised of the possibility of such loss.
Dosing, calculation, and analysis modules. The Reef Moonshiners module (including the assessment, classic calculator, dosing buddy, and product comparison tabs), and any other dosing, calculation, recommendation, or analysis tooling within the service, are provided as convenience utilities only. They may contain errors, may rely on third-party methodologies or community data that we do not control, and may produce results that are unsafe if acted upon without independent verification. You assume all risk arising from any decision to dose, add, or adjust any substance in your aquarium based on output from these tools. Subject to the carve-out at the head of this Section 9, we exclude all liability for any harm, loss, or damage — including to livestock, coral, equipment, water chemistry, or property — caused by, contributed to by, or arising from reliance on any calculation, dosing recommendation, target range, or product suggestion shown by the service.
Third-party recommendations. Third-party recommendations (for example, dosing suggestions included in a laboratory's ICP report, such as those from ReefZlements or Fauna Marin) are shown for information only, as published by that third party and calculated for the system volume it holds; we do not check, adjust, or endorse them. You act on them at your own risk, and the exclusion in the paragraph above applies to them in full.
Liability cap. Subject to the carve-out at the head of this Section 9, our total aggregate liability to you arising out of or in connection with these terms or your use of the service, whether in contract, tort (including negligence), breach of statutory duty or otherwise, shall not exceed the greater of (a) the total amount paid by you to us in the 12 months immediately preceding the event giving rise to the claim, or (b) £100 (one hundred pounds sterling).
You agree to indemnify and hold harmless Ark Technology Ltd, its officers, employees and agents, from and against all claims, demands, losses, liabilities, damages, costs and expenses (including reasonable legal fees) arising out of or relating to: (a) your breach of Section 4 (Acceptable use) or Section 5 (Third-party integrations); (b) your breach of any third party's terms of service when using credentials supplied through Reef Analysis; (c) any content, data, file or material you upload, enter or submit through the service infringing the intellectual property or other rights of any person; or (d) your acting on any output of the Reef Moonshiners module or other calculation tooling in a manner that causes loss to a third party.
We are not liable for any failure or delay in performing our obligations under these terms where such failure or delay arises from events outside our reasonable control, including (without limitation) acts of God, fire, flood, severe weather, epidemic or pandemic, war, terrorism, civil unrest, industrial action, failure of utility services or transport networks, outages or failures of internet or telecommunications providers, outages or failures of third-party platforms or APIs on which the service depends (including any of the device or laboratory platforms listed in Section 5), and acts or omissions of government or regulatory authority.
You may close your account at any time by contacting us at hello@reefanalysis.com.
We may suspend or terminate your account for material breach of these terms. Where reasonably possible we will give notice and a reasonable opportunity to remedy the breach before termination, except where the breach is incapable of remedy or is causing (or likely to cause) immediate harm to other users, third parties, or the service itself, in which case we may suspend or terminate immediately. Upon termination, your right to access the service ceases. Deletion of personal data following termination is dealt with in Section 6 (Data retention) of our Privacy Policy. Where we terminate a paid subscription without cause and other than for your breach, we will refund a pro rata portion of any pre-paid amount covering the unused period.
For material changes to these terms, we will give you at least 30 days' notice (by email or in-app notice) and require you to actively accept the revised terms via an in-app prompt before continuing to use the service. Non-material changes (typographical corrections, clarifications, updates to device or sub-processor lists that do not alter your rights or obligations) take effect when posted on this page. If you do not wish to accept material changes, you may close your account under Section 12 before the changes take effect.
Entire agreement. These terms (together with our Privacy Policy and any checkout-time terms you accept when subscribing) constitute the entire agreement between you and us in relation to the service, and supersede any prior agreement, understanding or representation, whether written or oral. You confirm that, in entering into these terms, you have not relied on, and shall have no remedy in respect of, any statement or representation not expressly set out here (save for fraudulent misrepresentation).
Severability. If any provision of these terms is held by a court or tribunal of competent jurisdiction to be invalid, unenforceable, or contrary to law, that provision shall be severed and the remaining provisions shall continue in full force and effect.
No waiver. A failure or delay by us in exercising any right or remedy under these terms does not constitute a waiver of that right or remedy. A single or partial exercise of any right or remedy shall not preclude any further exercise of it.
No assignment. You may not assign or transfer any of your rights or obligations under these terms without our prior written consent. We may assign or transfer our rights and obligations under these terms to any successor in business, group company, or purchaser of our assets, on giving you notice.
Third-party rights. A person who is not a party to these terms has no right under the Contracts (Rights of Third Parties) Act 1999 to enforce any of them.
These terms, and any non-contractual obligations arising out of or in connection with them, are governed by and construed in accordance with the laws of England & Wales. Subject to the following sentence, any disputes arising under or in connection with these terms shall be subject to the exclusive jurisdiction of the courts of England & Wales. If you are a consumer resident in another part of the United Kingdom, you may also bring proceedings in the courts of the part of the United Kingdom in which you reside, and the mandatory provisions of the law of that part of the United Kingdom apply to the extent they cannot lawfully be excluded.
This policy should be read alongside our Terms & Conditions. If you have any questions, contact us at hello@reefanalysis.com.
