1. About Lyseta Translate
Lyseta Translate (“the Service”) is a web application for managing software localization, operated by Lyseta Ltd, a company registered in England and Wales (company number 17167358) (“we”, “us”, “our”). The Service lets teams pin screenshots, notes, and shared glossaries to source strings, manage translations across multiple languages and versions, and optionally draft translations with AI assistance for human review.
Registered office: 71-75 Shelton Street, Covent Garden, London, WC2H 9JQ, United Kingdom. General enquiries: hello@lyseta.ai.
By creating an account or using the Service you agree to these Terms of Service. If you do not agree, please do not use the Service.
2. Accounts and organisations
You sign in using an email magic link, a supported OAuth provider (Google or GitHub), or, if your employer has configured it, your company's OIDC single sign-on provider. You are responsible for keeping your account secure and for all activity that takes place under it.
After signing in you must create or join an organisation. An organisation is a shared workspace containing one or more translation projects. The person who creates the organisation is its initial admin. Admins manage billing, seats, members, and integrations; they do not by default hold a project seat (and so cannot themselves create or edit project content) until they explicitly take one, which consumes a paid seat.
Within an organisation, content roles are Project Owner (full control of a project), Editor (context and glossary, no translation editing), and Translator (translation of specifically assigned languages only).
You must be at least 16 years old to use the Service. By creating an account you confirm that you meet this requirement.
3. Your content
You retain ownership of any source strings, translations, screenshots, glossary entries, notes, and other content you or your members upload to the Service (“Your Content”). By using the Service you grant us a limited, worldwide, royalty-free licence to store, process, transmit, and display Your Content to you and your authorised organisation members, solely for the purpose of operating the Service.
Content uploaded to an organisation is shared with all current and future authorised members of that organisation, subject to the per-language and per-role access controls described in the Service's documentation. When a member leaves or is removed, content they previously added remains with the organisation so the remaining members are not disrupted.
You are responsible for ensuring that Your Content does not infringe any third-party intellectual property rights and that you have the right to process any personal data it contains. You must not upload content that is unlawful, harmful, or offensive.
Screenshots may incidentally capture personal data appearing in your software. You are responsible for what you capture and for complying with applicable privacy law when you do so. Where you share content with translators (including freelance third parties you invite), it is your responsibility to ensure those people are permitted to see it under any confidentiality agreements you have with your customers or employer.
4. Subscription, billing, and refunds
The Service is billed on an annual subscription basis. The base plan includes a fixed number of seats and a monthly allowance of Lyseta tokens (the unit in which AI usage is metered). Additional seats and AI token top-up packs are available as paid add-ons. Current pricing is shown on the pricing page and at checkout in your local currency.
Payment is handled by Stripe. By subscribing you authorise us to charge your payment method on a recurring annual basis, and to charge for in-app purchases (additional seats added mid-cycle, token top-ups) at the moment of purchase. You can manage your payment method, change seat counts, and cancel from the in-app billing page. Cancellation takes effect at the end of the current billing period; you retain access until then.
Prices are shown in your local currency where supported (currently GBP, USD, EUR, AUD, and CAD), based on the country from which you first set up the organisation. Once you subscribe, Stripe locks the currency on your subscription and subsequent charges will be made in that currency. The subscription currency cannot be changed after the first subscription is created, including on request; if you need a different currency, cancel the subscription and create a new organisation. We are not currently VAT-registered, so no VAT is charged. Prices may change with reasonable notice; we will notify you before any price change takes effect.
By subscribing and starting to use the Service you expressly consent to immediate performance of the Service and acknowledge that you lose the 14-day right to cancel a digital service under the UK Consumer Contracts Regulations 2013. This consent does not apply if you have signed up as a consumer rather than for business use, in which case your statutory rights apply.
Subscriptions and AI token top-up packs are non-refundable, except where a refund is required by law. We may, at our sole discretion, offer a goodwill refund in individual cases where the circumstances warrant it (for example, a clearly unintended renewal that you flag promptly). Discretionary goodwill refunds are not a right and do not set a precedent for future requests. To ask, email us at hello@lyseta.ai.
We do not store your card details. All payment information is handled securely by Stripe; their terms apply to payment processing.
5. Free trial
New organisations begin with a 14-day free trial that includes a small allowance of Lyseta tokens. The trial begins the first time a paid seat is consumed (for example, when the first content member is invited). A valid payment method is required at signup but is not charged until the trial ends, unless you choose to skip the trial and upgrade immediately. You may cancel from the billing page at any time during the trial to avoid the upcoming charge.
6. AI translation and other AI features
The Service uses third-party AI models (currently Anthropic's Claude) to draft translations, generate glossary suggestions, and perform related tasks at your request. AI usage is metered in Lyseta tokens against your organisation's monthly grant and any top-up balance.
To the fullest extent permitted by law, we accept no liability for any loss, damage, reputational harm, legal exposure, regulatory consequence, mistranslated meaning, or other harm arising from reliance on AI-generated translations or other AI output, including any harm caused by translations that were not properly reviewed before being shipped. Your use of these features is at your own risk. This does not affect liability that cannot be limited or excluded by law (see section 11).
Source strings, translations, glossary entries, screenshots, and notes that you submit for AI processing are sent to Anthropic and processed under their commercial API terms. Inputs and outputs are not used to train Anthropic's models; Anthropic processes them to generate the response and may retain them for a limited period for safety and abuse monitoring, after which they are deleted in line with their published retention practice. We ourselves do not train, fine-tune, or evaluate any machine-learning model on Your Content, and do not use Your Content to build analytics or derivative products. If you cannot send your content to a third-party AI processor, do not use the AI features — every AI affordance in the Service is opt-in at the organisation level and can be disabled by an admin.
EU AI Act posture. The AI features of the Service are an assistive drafting tool that produces translation suggestions for mandatory human review. We do not market or operate the Service as a high-risk AI system within the meaning of the EU AI Act, and the Service is not intended for use cases that would constitute high-risk AI under Annex III of the Act. AI-generated content is clearly marked within the Service as awaiting review, and the AI features can be disabled at the organisation level at any time. You are responsible for assessing whether your particular use case carries any AI-related risk that requires further measures on your side, and for not using the AI features if you decide it does. We may update the AI model used to provide these features without notice, provided any replacement is subject to equivalent commercial data-handling terms.
7. Acceptable use
You agree not to:
- Use the Service for any unlawful purpose
- Attempt to gain unauthorised access to other users' data
- Upload malware, exploit code, or content designed to harm the Service or its users
- Abuse AI features through automated bulk requests beyond what the in-product UI provides
- Reverse-engineer, scrape, or extract data from the Service other than via the documented export functionality
- Use the Service in a way that could damage, disable, overload, or impair it
We reserve the right to suspend or terminate accounts that materially violate these rules.
8. Members you invite
You are responsible for the people you invite to your organisation, including freelance translators or external contractors. This includes ensuring they are authorised to view the content you share with them, that they comply with these terms, and that you have any necessary confidentiality or data-processing arrangements in place with them. If an invited member breaches these terms, we may treat that as a breach by your organisation.
9. Copyright and takedown
We respect intellectual property rights. If you believe content in a Lyseta Translate organisation infringes your copyright, please contact us at hello@lyseta.ai with:
- A description of the work you claim has been infringed
- The specific content you believe infringes it (with enough detail for us to locate it)
- Your contact details
- A statement that you have a good-faith belief the use is not authorised
- A statement that the information you provide is accurate
We will review the notice and, where appropriate, remove or restrict access to the content. We may notify the organisation whose content is affected.
10. Service availability
We aim to keep the Service available but do not guarantee uninterrupted access. We may carry out maintenance, updates, or changes at any time. We are not liable for any losses arising from downtime or service interruption.
We reserve the right to modify or discontinue the Service, or any feature of it, at any time. If we discontinue the Service entirely or remove a material feature you depend on, we will provide reasonable notice and, where practical, an opportunity to export your translations.
11. Termination and data retention
You may cancel your subscription or delete your account at any time from the billing or account pages. On cancellation, your organisation's data is retained on our systems so that you can resubscribe and resume work without loss; we do not automatically delete it on cancel. If you want your data permanently deleted, request deletion in writing (see the Privacy Policy for how) and we will remove it within the timeframe set out there, except where we are required to retain certain records (for example billing records) for legal reasons.
We may suspend or terminate your account if you materially breach these terms, if your use of the Service creates legal risk for us, or if your account has been inactive for an extended period. Where possible we will give you notice and an opportunity to remedy the breach.
12. Limitation of liability
Nothing in these terms limits or excludes our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot be limited or excluded by law.
Subject to the above, the Service is provided “as is” without warranties of any kind, express or implied. To the fullest extent permitted by law, we exclude all liability for indirect, incidental, special, or consequential losses arising from your use of the Service, including loss of profit, loss of revenue, loss of business, loss of goodwill, loss of data, or wasted expenditure.
Our total liability to you for any claim arising out of or in connection with these terms shall not exceed the amount you paid us in the twelve months preceding the claim, or £100, whichever is greater.
13. Changes to these terms
We may update these terms from time to time. We will notify you of material changes by displaying a notice in the app or by email. Continued use of the Service after changes are posted constitutes acceptance of the revised terms.
14. General
Severability. If any provision of these terms is found to be unenforceable, the remaining provisions continue in full force and effect.
Entire agreement. These terms, together with the Privacy Policy, form the entire agreement between you and us regarding the Service and supersede any previous agreements or understandings.
No assignment. You may not assign or transfer your rights under these terms without our written consent. We may assign our rights under these terms to a successor entity (for example on sale of the business) on reasonable notice.
Force majeure. We are not liable for failure or delay in performance caused by events outside our reasonable control, including infrastructure outages, acts of government, or disruption to third-party services we rely on (such as our hosting provider, AI provider, or payment processor).
No 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 its provisions.
15. Governing law
These terms are governed by the laws of England and Wales. Any disputes shall be subject to the exclusive jurisdiction of the courts of England and Wales. Nothing in this clause affects the mandatory rights of consumers resident elsewhere in the UK.
