Terms of Service
These Terms are the agreement between you and Sylphx Limited for using Sylphx. Please read them, especially the key terms summarised first: they explain who is responsible for what happens under your account and the limits of our liability.
Key terms
- You are responsible for everything done under your account, including by API keys, tokens, automations and AI agents you authorise.
- The service is provided “as is”. AI output can be wrong: check it before you rely on it.
- We may change features, prices, usage limits and these terms, and suspend or end accounts, as these terms explain.
- For business customers: our liability is limited to the fees paid in the previous 12 months, you indemnify us for claims arising from your use, claims must be brought within one year and only individually, and the courts of England and Wales have exclusive jurisdiction.
- If you are a consumer, your legal rights, including under the Consumer Rights Act 2015 and your 14-day right to cancel, are not affected.
This summary points to terms set out in full below; the numbered clauses are the contract.
1. Who We Are and These Terms
Who you are contracting with, who counts as a consumer, and who is bound.
Sylphx ("the Service") is provided by Sylphx Limited, a company registered in England and Wales (company number 16438428) ("we", "us", "our"). Registered office: 128 City Road, London EC1V 2NX. These Terms of Service ("Terms") are the agreement between you and us. By creating an account or using the Service you accept them. If you do not accept them, do not use the Service.
- Consumer
- An individual using the Service wholly or mainly outside their trade, business, craft or profession.
- Business customer
- Anyone who is not a consumer, including a company, sole trader, developer building for a business, school or other organisation.
- You
- The account holder. If you accept these Terms for an organisation, you confirm you may bind it, and “you” includes it.
- Signed agreement
- A separate order form or agreement signed by us. Where it conflicts with these Terms, the signed agreement wins.
2. The Service
What the Service covers, and our right to change it.
Sylphx is a platform for building, deploying and running applications, including authentication, billing, data, storage, AI model access, background jobs, messaging, observability and related services, as described on this site from time to time.
We keep developing the Service. We may add, change, suspend or remove features, services, AI models, regions, integrations and plans at our discretion. If a change materially reduces a paid feature you are using, we will tell you where we reasonably can, and you can cancel. Features marked preview, beta or experimental are provided as they are and may change or end at any time.
Usage limits. We may set and change quotas, rate limits, fair-use limits and spend limits, and slow, queue or pause use that exceeds them, to protect the Service and other customers. We may monitor use of the Service, including automatically, to detect abuse, fraud, security threats and breaches of these Terms.
3. Your Account
Who may hold an account, and who answers for what happens under it.
To hold an account you must:
- be at least 18, or the age of majority where you live if that is higher;
- give accurate, complete information and keep it current;
- not be barred from receiving the Service under UK or other applicable sanctions law;
- keep your credentials, API keys and tokens secure, and tell us at support@sylphx.com if you think they have been compromised.
You are responsible for all activity under your account and your projects, including activity by your team members, by anyone using your credentials, API keys or tokens, and by automations, CI pipelines and AI agents you authorise. We may refuse to open an account or to provide the Service to anyone, at our discretion.
4. Acceptable Use
What you may not do with the Service, and what we may do if you do.
You must not use the Service, or let anyone else use it, to:
- break any law or regulation, or help anyone else to;
- infringe anyone's intellectual property, privacy or other rights;
- transmit malware or other harmful code;
- collect or scrape data without authorisation;
- gain or attempt unauthorised access to any system, account or data;
- interfere with, disrupt or overload the Service or its infrastructure;
- send spam or other unsolicited communications;
- impersonate anyone or misrepresent your affiliation;
- mine cryptocurrency, or run workloads designed to evade usage limits or billing;
- copy, resell, sublicense or reverse engineer the Service, except as the law expressly allows, or use it to build a competing service; or
- any other illegal, fraudulent, harmful or abusive purpose.
We may, without notice, remove or block content, disable a project, deployment, key or feature, or suspend your account where we reasonably believe these rules are broken or the Service, our customers or others are at risk. We will usually tell you why, unless the law, security or safety prevents it. Copyright complaints follow the copyright process.
5. Fees, Payment and Cancellation
Usage-based fees, price changes, refunds, and the consumer 14-day right.
Plans, prices and usage rates are on the pricing page. You agree to pay all fees for your plan and your usage, plus taxes such as VAT where the law requires them, and to keep a valid payment method on file. Usage is measured by our systems, and our records are final unless shown to be wrong. Included credit and allowances expire as stated when granted and do not carry over unless we say otherwise.
Price changes. We may change our prices and usage rates. If you are a consumer, we will give you reasonable notice before a new price applies to you, and you can cancel before it does. If you are a business customer, a new price applies from the date we publish or tell you.
Failed payment. If a payment fails or is overdue, we may suspend paid features, projects or the account until it is paid, and recover the amount owed.
Refunds. Fees are not refundable, including for part periods and unused credit or allowance, except where these Terms or the law say otherwise. If we charge you in error, tell us and we will correct it.
Your 14-day right to cancel (consumers). If you are a consumer in the UK or the EU, you may cancel a new paid plan within 14 days of buying it, without giving a reason, by telling us at support@sylphx.com. Because you ask us to start the Service straight away, we refund what you paid minus a proportionate amount for the Service and usage you had before you told us, as the law provides. If you are a consumer and we did not provide the Service with reasonable care and skill, you have the remedies the law gives you.
6. Your Content and Our Property
What you own, the licence you give us, and who owns the platform.
Your content. As between you and us, you own the code, data and other content you and your applications put into the Service. You confirm you have all the rights needed for it. You give us a worldwide, royalty-free, non-exclusive licence to host, store, copy, process, transmit and display your content, and to let our sub-processors do so, as needed to provide, secure, support and improve the Service. The licence lasts while your content is in the Service and for the limited period deleted data remains in backups.
Usage data. We may create aggregated or de-identified data about how the Service is used, which does not identify you or any other person, and use it for any purpose.
Our property. The Service, including its software, SDKs, documentation, design and name, belongs to Sylphx Limited and its licensors. We give you a personal, non-exclusive, non-transferable, revocable right to use it under these Terms. SDKs and tools we publish under an open-source licence are governed by that licence.
Feedback. If you send us feedback or suggestions, you give us a perpetual, irrevocable, worldwide, royalty-free licence to use them for any purpose, without owing you anything.
7. AI Features and Third-Party Services
AI output is not guaranteed; third-party services run on their own terms.
AI output. AI features use models provided by third parties. Output can be wrong, incomplete, offensive or out of date, even when it sounds confident, and it is not professional advice. We do not promise that output will be accurate, complete, original or fit for any purpose. You are responsible for reviewing output and for how you and your applications use it.
Third-party services. Services you connect or that the Service passes requests to on your instruction — such as AI model providers, source-code hosts, payment providers, domain registrars and identity providers — are provided by third parties under their own terms, which apply to your use of them. We do not control them and are not responsible for their availability, output, security or conduct, or for changes they make.
8. Availability
No uptime promise in these Terms; any service level lives in a signed agreement.
The Service is provided “as available”. We do not promise that it will be uninterrupted, error-free or secure, or any particular uptime, and it may be unavailable, including for maintenance, security updates and events outside our reasonable control. A service level commitment applies only if it is set out in a signed agreement, and the remedies in that agreement are your only remedies for failing to meet it. You are responsible for keeping your own backups and exports of content you cannot afford to lose.
9. Data Protection
Our Privacy Policy, and the terms on which we process your end users’ data.
How we handle personal data as a controller — for example your account and billing details — is described in our Privacy Policy.
Where you use the Service to process personal data about your own users or others, you are the controller of that data and we are your processor. You are responsible for having a lawful basis and giving any notices the law requires. For that data we:
- process it only on your documented instructions — these Terms, your configuration of the Service, and your use of the console, CLI, API and SDKs — unless the law requires otherwise, and tell you if we believe an instruction breaks data protection law;
- ensure the people who can access it are bound to keep it confidential;
- protect it with appropriate technical and organisational measures, such as those on the security page, which we may update provided the overall level of protection is not materially reduced;
- use the sub-processors listed on this site, under written terms with the same data protection obligations, and remain responsible for them as the law requires. You authorise us to use them and to add or replace sub-processors; we will tell you of an intended change by updating that list at least 10 days before the change. If you object on reasonable data protection grounds within that period, your remedy is to stop using the affected part of the Service;
- help you, taking into account the nature of the processing and the information we have, to answer requests from the people the data is about (including through the Service's export and deletion features) and to meet your duties on security, breach notification and impact assessments. We may charge reasonable costs for help beyond those features;
- tell you without undue delay after we become aware of a breach affecting it;
- delete it when you delete it or close your account, unless the law requires us to keep it. You can export it first while your account is active;
- make available the information needed to show these duties are met, and allow audits by you or an independent auditor bound by confidentiality — on reasonable notice, at your cost, no more than once a year unless a regulator requires it or after a breach, and first by written answers and our documentation where those are enough.
Transfers outside the UK or EEA follow the safeguards in the Privacy Policy. Business customers can ask for our signed data processing agreement at contact@sylphx.com.
10. Suspension and Termination
How either side ends the agreement, and what continues afterwards.
You may stop using the Service and close your account at any time. We may suspend or end your access, in whole or in part, immediately and without notice if you break these Terms, do not pay, if we reasonably believe your use puts us, our customers or others at risk, or if the law or a regulator requires it. We may also end this agreement for any other reason by giving you reasonable notice.
When the agreement ends, your right to use the Service ends, and we may delete your content. Export anything you need before then; where we think it appropriate, we may give you time to do so. If we stop offering the Service, we will give you reasonable notice and refund fees you paid in advance for the time after it ends.
Terms that by their nature should continue after the agreement ends — including those on content, feedback, fees owed, liability, indemnity and disputes — continue to apply.
11. Liability and Indemnity
What we are and are not responsible for, for consumers and for business customers.
Nothing in these Terms limits or excludes liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for anything else the law does not allow us to limit or exclude.
If you are a consumer, we are responsible for loss you suffer that is a foreseeable result of our breaking these Terms or failing to use reasonable care and skill. We are not responsible for loss that was not foreseeable, for business losses, or for loss caused by events outside our reasonable control. Unless we broke these Terms or failed to use reasonable care and skill, we are not responsible for actions taken under your credentials or by automations and agents you authorised, for AI output, or for third-party services. If defective digital content we supplied damages a device or digital content belonging to you, we will repair the damage or compensate you, as the law requires. Your legal rights as a consumer are not affected.
If you are a business customer, each of the following applies separately:
- The Service is provided “as is” and “as available”. To the extent the law allows, all warranties, conditions and terms implied by statute or common law are excluded, including those about satisfactory quality, fitness for purpose and reasonable care and skill.
- We are not liable, whether in contract, tort (including negligence), breach of statutory duty or otherwise, for: indirect or consequential loss; loss of profits, revenue, business, contracts, anticipated savings or goodwill; loss or corruption of data; AI output; actions taken under your account, credentials, API keys or tokens or by automations and agents you authorised; or third-party services.
- Our total liability arising from or in connection with these Terms and the Service is limited to the fees you paid us in the 12 months before the event giving rise to the claim.
- You will indemnify us, and keep us indemnified, against all claims, losses, damages, fines, costs and reasonable legal fees arising from your content, your applications and their users, your use of the Service, or your breach of these Terms or the law.
12. Changes, Law and Disputes
How these Terms change, the law of England and Wales, and where claims are brought.
Changes to these Terms. We may change these Terms, for example to reflect changes to the Service, our prices or providers, the law or security needs. We will post the new version here and update the date above. If you are a consumer, we will give you reasonable notice of a material change before it applies to you, and you can cancel before then. If you are a business customer, a change applies from the date we give when we post or send it. Continuing to use the Service after a change applies means you accept it.
Disputes. These Terms, and any dispute about them or the Service, including non-contractual disputes, are governed by the laws of England and Wales. If something goes wrong, email support@sylphx.com first.
If you are a consumer, the courts of England and Wales have non-exclusive jurisdiction: you keep the protection of the mandatory law where you live, and you may bring a claim in the courts of Scotland or Northern Ireland, or of your EU country, if you live there.
If you are a business customer, the courts of England and Wales have exclusive jurisdiction. To the extent the law allows, you may bring a claim only in your own name, not as a claimant or member in any class, group or representative action, and any claim must be brought within one year after you knew, or should have known, of the facts giving rise to it.
13. General
Transfer, third parties, severability and the rest of the boilerplate.
- Transfer
- We may transfer this agreement, or any of our rights or duties under it, to another company, and may use subcontractors. If you are a consumer, we will tell you of a transfer, it will not reduce your rights, and you may end the agreement if you are unhappy. You may not transfer your rights or duties without our written consent.
- Events outside our control
- We are not responsible for delays or failures caused by events outside our reasonable control, including failures of hosting, network, AI model or other third-party providers.
- Third parties
- Nobody else has rights under these Terms.
- Severability
- If a court finds part of these Terms invalid, the rest still applies, and the invalid part applies to the extent the law allows.
- No waiver
- If we do not enforce a term straight away, we can still enforce it later.
- Entire agreement
- For business customers, these Terms and any signed agreement are the whole agreement between us about the Service, and you have not relied on any statement not set out in them.
