Terms of Use

Segura Dashboard and Segura Public API — app.segura-water.com

Version 2026-09-01 · Last updated: 1 September 2026

1. Introduction and acceptance

These Terms of Use ("Terms") govern your access to and use of the Segura Dashboard at app.segura-water.com, the Segura Public API at app.segura-water.com/api, their documentation, and any data, output, or software made available through them (together, the "Platform").

These Terms form a binding agreement between you and us. You accept them by any of the following, whichever happens first: creating a Dashboard account; signing in; being issued or using an API key; or otherwise accessing the Platform. If you do not agree to these Terms, do not use the Platform.

If you are accepting these Terms on behalf of an organisation, you represent that you have authority to bind that organisation, and "you" means that organisation. These Terms apply to your employees, contractors, and agents, and you are responsible for their compliance.

These Terms govern the Platform. The public marketing site at segura-water.com is governed by its own Terms of Use. Where a signed written agreement between you and us covers the same subject matter, that agreement prevails over these Terms to the extent of any conflict.

2. About us

The Platform is operated by Advanced Water Testing Ltd, trading as Segura, a company registered in England and Wales, with its registered office at 3rd Floor, 86–90 Paul Street, London EC2A 4NE, United Kingdom. "We", "us", and "our" refer to Advanced Water Testing Ltd.

3. Definitions

• "Platform" — as defined in section 1, including the Dashboard, the API, the Segura mobile application where it connects to either, and all associated software, interfaces, and documentation.
• "Your Data" — measurement records, sample metadata, photographs, notes, and account details that you or your organisation submit to or generate on the Platform.
• "Platform Materials" — everything else: the software, source and object code, the signal processing pipeline, calibration models, detection and peak-identification algorithms, analytical methods, compliance rule sets, reference datasets, schemas, API design, documentation, user interface, and the Segura name and marks.
• "Output" — concentrations, qualifiers, compliance determinations, summaries, and exports that the Platform produces from Your Data.

4. Accounts and access

Dashboard accounts are granted by administrator approval, not by self-service signup alone. API keys are issued individually by a Segura administrator. Access is personal to the account or key holder and is licensed, not sold.

• Provide accurate registration details and keep them current.
• Keep credentials confidential. Do not share, publish, resell, or sublicense an account or API key, and do not allow anyone outside your organisation to use one. The published demo key (segura_demo_public_2026) is the sole exception: it is deliberately public, serves only synthetic data, and may be used freely subject to these Terms.
• You are responsible for all activity under your credentials. Tell us promptly at [email protected] if you believe a credential has been compromised, and we will revoke it.
• Do not create an account or obtain a key by misrepresenting who you are or who you work for, or on behalf of a competitor for the purpose of evaluating or replicating the Platform.

5. Licence granted to you

Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable licence to access and use the Platform, and to use the Output, for your own internal water-quality testing, monitoring, reporting, and regulatory purposes.

That licence includes the right to store, analyse, and redistribute Output that relates to your own samples — including publishing results, filing them with a regulator, or passing them to a client. It does not include any right to the Platform Materials beyond using them as the Platform intends.

All rights not expressly granted are reserved. No right is granted by implication, estoppel, or otherwise.

6. Restrictions — reverse engineering and derivation

This section is the core of these Terms. Segura's value is in how a raw voltammetric sweep becomes a defensible concentration, and that method is proprietary. You must not do any of the following, and must not permit or assist any third party to do them.

6.1 Reverse engineering

• Reverse engineer, decompile, disassemble, deobfuscate, or otherwise attempt to derive or reconstruct the source code, object code, underlying ideas, algorithms, file formats, or internal structure of the Platform or any part of it, by any means.
• Attempt to discover, reconstruct, replicate, or approximate the signal processing pipeline, filtering and baseline-correction methods, peak detection and identification logic, calibration curves, calibration constants, detection and quantitation limits, or analytical methods used by the Platform — whether from the software, from the API, from Output, from documentation, or by inference from observed behaviour.
• Conduct black-box analysis, probing, or systematic input-output experimentation whose purpose or effect is to characterise or recreate any method described above, including submitting contrived, spiked, or synthetic inputs for that purpose.
• Use the Platform, the Output, or any part of the Platform Materials as training data, reference data, or evaluation data for machine-learning or statistical models intended to reproduce, substitute for, or compete with the Platform or any of its methods.
• Remove, obscure, or alter any proprietary notice, watermark, attribution, version identifier, or provenance field.

Where applicable law grants you a non-waivable right to decompile software for interoperability, nothing here limits that right — but you must first give us written notice at [email protected] and a reasonable opportunity to supply the interoperability information you need. We will normally do so, because a documented interface is better for both of us than a guessed one.

6.2 Copying and competition

• Copy, modify, adapt, translate, or create derivative works of the Platform or the Platform Materials, except as these Terms expressly permit.
• Sell, rent, lease, lend, sublicense, distribute, host as a service, or otherwise make the Platform available to any third party.
• Use the Platform to build, train, specify, validate, or market a product or service that competes with Segura, or to assist anyone else in doing so.
• Publish benchmarks, comparative performance claims, accuracy assessments, or competitive analyses of the Platform without our prior written consent. This does not restrict you from reporting your own measurement results, from discussing your experience of the Platform, or from any disclosure required by law or by a regulator.
• File any patent application claiming subject matter derived from the Platform Materials.

6.3 Security and integrity

• Circumvent, disable, or interfere with authentication, authorisation, rate limiting, audit logging, the demo/real data separation, or any other security or integrity control.
• Access any account, key, data, or system you are not authorised to access, or probe, scan, or test the vulnerability of the Platform without our prior written permission. We welcome good-faith security reports — write to [email protected] first.
• Introduce malware or any code intended to damage, disrupt, or gain unauthorised access to the Platform, or interfere with another user's use of it.
• Present synthetic or demo data as genuine measurement results. Demo records are flagged (isDemo: true, "mode": "demo") and served from a separate database. Stripping, ignoring, or suppressing those markers when data leaves the Platform is a breach of these Terms.
• Falsify, backdate, or tamper with measurement records, provenance fields, or compliance determinations.

7. Acceptable use of the API

The API is read-only and rate limited to 120 requests per minute per key. In addition to section 6:

• Do not scrape, crawl, or bulk-extract beyond what your own integration genuinely needs, and do not use multiple keys, distributed clients, or rotating addresses to exceed the published limits.
• Use the documented incremental sync parameters rather than repeatedly re-downloading the full dataset.
• Do not build a mirror, cache, or republished copy of the dataset that is made available to anyone outside your organisation.
• We may change, deprecate, or withdraw endpoints. Breaking changes to /api/v1 will be announced to key holders in advance where reasonably practicable.

8. Confidentiality and trade secrets

The Platform Materials — in particular the signal processing pipeline, its parameters, and the calibration and analytical methods — are our confidential information and trade secrets, protected under the Trade Secrets (Enforcement, etc.) Regulations 2018 and the general law of confidence. Providing you with access to the Platform does not place them in the public domain.

You must keep them confidential, use them only as these Terms permit, and not disclose them to any third party. This obligation survives termination and continues for as long as the information remains a trade secret. It does not apply to information that is or becomes public through no act of yours, that you already lawfully held without restriction, or that you are required to disclose by law or court order — in which case, tell us first if you lawfully can.

You acknowledge that damages alone would be an inadequate remedy for breach of section 6 or this section, and that we are entitled to seek injunctive relief and specific performance without needing to prove special damage or provide security.

9. Intellectual property

We and our licensors own all right, title, and interest in the Platform Materials, including all copyright, database rights, trade secrets, patents, trademarks, and other intellectual property in them. These Terms grant a licence to use the Platform; they transfer no ownership.

"Segura", the Segura logo, and related product names are trademarks of Advanced Water Testing Ltd. You may not use them without our written consent, except to identify the Platform accurately in factual statements.

If you send us feedback, suggestions, or bug reports, we may use them without restriction or obligation to you. You are not required to send us feedback.

10. Your data

Your Data remains yours. You grant us a non-exclusive, worldwide licence to host, store, process, transmit, back up, and display it solely to operate and support the Platform for you, to keep it secure, and to comply with law.

We may compute aggregated and de-identified statistics from Your Data to operate, secure, and improve the Platform. Anything so derived will not identify you, your organisation, your customers, or any specific sampling location, and we will not publish or sell Your Data.

You are responsible for the accuracy and lawfulness of what you submit, for having the right to submit it, and for retaining your own copies. Exports are available through the Dashboard and the API — use them. On termination we may delete Your Data after a reasonable period; ask us before then if you need an extract.

11. Screening tool, not a certified laboratory

The Platform is intended for use by trained water-testing professionals, utilities, and authorised partners. Results depend on sample handling, strip condition, calibration currency, dilution, and operating conditions that are outside our control.

Read qualifiers before values. A null value with a not_detected qualifier means no peak was found; it does not mean zero and must not be recorded as zero. below_detection is not a pass. A compliance status is judged against a named standard given alongside it, and an action level is not a per-sample health limit. Misreading these is the most likely way to reach a wrong conclusion from correct data, and you are responsible for reading them correctly.

12. Availability and changes

We aim to keep the Platform available but do not guarantee uninterrupted or error-free operation. We may modify, suspend, or discontinue any part of it, and will give reasonable notice of material adverse changes where practicable. Maintenance, updates, and emergency security work may cause downtime without notice.

13. Suspension and termination

We may suspend or terminate your access, revoke an API key, or close an account immediately and without notice if we reasonably believe you have breached section 6, section 7, or section 8, or where required by law or necessary to protect the Platform or its users. For other breaches we will give notice and a reasonable chance to fix the problem where it is capable of being fixed.

You may stop using the Platform at any time; ask us to close your account or revoke your keys and we will. Sections 6, 8, 9, 10, 14, 15, 16, 20, and 21 survive termination.

14. Disclaimer of warranties

To the fullest extent permitted by law, the Platform and the Output are provided "as is" and "as available". We make no representations or warranties, express or implied, including any implied warranty of satisfactory quality, fitness for a particular purpose, non-infringement, accuracy, or uninterrupted availability. Any reliance you place on the Platform or the Output is at your own risk, subject to section 15.

15. Limitation of liability

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

Subject to that, we will not be liable to you — whether in contract, tort (including negligence), breach of statutory duty, or otherwise — for any loss of profit, loss of business, business interruption, loss of anticipated savings, loss of goodwill, loss or corruption of data, or any indirect or consequential loss, arising under or in connection with the Platform.

Subject to the first paragraph of this section, our total aggregate liability arising under or in connection with these Terms in any twelve-month period will not exceed the greater of (a) the total fees you paid us for the Platform in that period, and (b) £1,000.

16. Indemnity

You will indemnify us against all liabilities, costs, and reasonable legal expenses arising from your breach of section 6, section 7, or section 8, from your unlawful use of the Platform, or from a third-party claim that Your Data infringes their rights or was submitted unlawfully.

17. Privacy

Your use of the Platform is also governed by our Privacy Policy, which explains how we handle personal data under the UK GDPR and the General Data Protection Regulation. Sample metadata you submit may include operator names and GPS positions; you are responsible for having a lawful basis to submit personal data about other people.

18. Export control and sanctions

You must comply with all applicable export control and sanctions laws. You may not access or use the Platform if you are subject to UK, EU, UN, or US sanctions, and you may not make the Platform available to anyone who is.

19. Changes to these Terms

We may update these Terms. The current version is always published at app.segura-water.com/terms and carries a version stamp at the top of the page. We will give notice of material changes by email to account holders and key holders, or in the Dashboard, before they take effect. Continuing to use the Platform after that means you accept the revised Terms.

20. General

• Entire agreement. These Terms, together with any signed agreement between us, are the whole agreement about the Platform and replace any earlier understanding on the same subject.
• No waiver. A delay or failure to enforce any right is not a waiver of it.
• Severance. If any provision is held unenforceable, it is modified to the minimum extent needed to make it enforceable, or severed; the rest stands.
• Assignment. You may not assign or transfer these Terms without our written consent. We may assign them to an affiliate or in connection with a merger, acquisition, or sale of assets.
• Third parties. No one other than you and us has any right to enforce these Terms under the Contracts (Rights of Third Parties) Act 1999.
• Force majeure. Neither party is liable for failure to perform caused by events beyond its reasonable control.

21. Governing law and jurisdiction

These Terms, and any dispute or claim arising out of or in connection with them or the Platform (including non-contractual disputes or claims), are governed by and construed in accordance with the laws of England and Wales. The courts of England and Wales have exclusive jurisdiction, save that we may seek injunctive relief in any court of competent jurisdiction to protect our intellectual property or confidential information.
