Terms of Service
Effective date: 28 October 2025
1. Introduction
Welcome to Leo (the "Service"), operated by Leo Technologies Limited ("Leo", "we", "us", or "our"), a company registered in England and Wales (company number 16019040). Leo is an AI-powered manuscript transcription platform that allows users to upload images of documents, create transcriptions, manage associated metadata, and securely store these materials. By accessing or using our web application or any associated services, you agree to these Terms of Service ("Terms") and our Privacy Policy. If you do not agree with these Terms, you must not use Leo.
2. User accounts
Account registration: To use Leo, you must create a personal user account. You agree to provide accurate, current, and complete information during registration and to keep your account information up-to-date. Each user must register for their own account – you may not create an account for anyone other than yourself, and you must not share your login credentials.
Account responsibility: You are responsible for maintaining the confidentiality of your account login details and for all activities that occur under your account. If you suspect any unauthorized use of your account, you must notify us immediately. We are not liable for any loss or damage arising from your failure to safeguard your account credentials.
Eligibility: You must be at least 18 years old (or the age of majority in your jurisdiction) to create an account and use the Service. By registering, you represent and warrant that you meet this age requirement and are otherwise legally capable of entering into this agreement. If you are registering on behalf of an organization, you represent that you have the authority to bind that entity to these Terms.
3. Subscriptions and payments
Subscription plans: Leo is a subscription-based service. We offer multiple subscription tiers (as described on our website or pricing page) which grant you access to varying levels of usage and features. In order to use Leo's transcription and storage features beyond any free trial or free tier (if offered), you must select a subscription plan and provide a valid payment method.
Payment processing: All subscription fees are payable in advance and will be billed on a recurring basis (e.g., monthly) according to your chosen plan. Payments are processed securely through our third-party payment processor, Stripe. By providing a payment method, you authorize us and Stripe to charge the applicable subscription fees to that payment method.
Auto-renewal: Your subscription will automatically renew at the end of each billing cycle unless you cancel it prior to the renewal date. You are responsible for timely payment of all fees and for maintaining current billing information.
Upgrades and downgrades: If you upgrade your subscription plan, the higher fees will apply immediately and may be prorated for the remaining period in your billing cycle. If you choose to downgrade your plan or cancel your subscription, the change will take effect at the end of the current billing period unless otherwise stated.
Cancellation and refunds: You may cancel your subscription at any time. If you cancel or downgrade your subscription, this will take effect at the end of your current billing period.
4. User content and rights
Ownership of content: You retain all rights and ownership of the content you upload to Leo (e.g., manuscript images, transcripts, metadata). We do not claim ownership of your content.
License to Leo: By uploading or creating content on the Service, you grant Leo a worldwide, royalty-free, non-exclusive license to use, copy, store, modify, and create derivative works from your content for the sole purpose of operating, maintaining, and improving the Service. This includes providing the transcription feature, troubleshooting, and refining our AI models.
Sub-licensing to service providers: You agree that Leo may sub-license these rights to trusted third-party providers (e.g., hosting or AI processing), under obligations of confidentiality and security.
Your responsibilities: By uploading content, you represent and warrant that:
- You have all necessary legal rights and permissions to upload that content and grant Leo the license described.
- Use of your content by Leo does not infringe or violate any law or third-party rights.
Sharing of content: The Service may allow you to share your content with others, either publicly or with specific users. You are solely responsible for any content you choose to share and for ensuring that you have all necessary rights and permissions to do so. Leo does not review or approve shared content and is not responsible for any unauthorized sharing, publication, or distribution of materials by users.
5. Data usage and retention
Use of uploaded content: We use your uploaded content to provide and improve the Service, including training our AI models. We will not disclose your content to third parties except as required to deliver our Service or by law.
Retention of personal data: We do not retain your personal data after you delete your account, except as required by law or for legitimate business interests (e.g., billing records). Personal data is handled in accordance with our Privacy Policy.
Deletion and limited retention: If you delete your content or close your account, we may retain and use non-personal or anonymized portions (e.g., manuscript images, transcripts, metadata) to enhance our Services, with access limited to authorized personnel. To request complete erasure of all non-personal data, please contact us at support@tryleo.ai (fees may apply).
6. Acceptable use and content restrictions
Lawful use only: You agree to use Leo only for lawful purposes. You must not upload any content that is illegal, fraudulent, defamatory, or otherwise violates any law or regulation.
No personal data: You must not upload any images or other materials containing personal data of living individuals without explicit rights and consents. The Service is not intended for processing sensitive or personal data.
Intellectual property compliance: You must not upload or share any content that you do not have the right to use, including copyrighted materials. You are responsible for ensuring you have the necessary rights or permissions from third-party owners.
Service integrity: You must not interfere with the Service, introduce viruses or harmful code, or attempt to circumvent security measures.
7. Indemnification
You agree to indemnify, defend, and hold harmless Leo Technologies Limited and its officers, directors, employees, and agents from and against any claims, liabilities, damages, losses, or expenses (including legal fees) arising out of or in connection with:
- Your content or your use of the Service.
- Your violation of these Terms or any applicable law or regulation.
- Your infringement of any rights of a third party, including intellectual property or privacy rights.
8. Service availability and disclaimers
Availability: We strive to keep Leo operational at all times but do not guarantee uninterrupted or error-free service. Downtime may occur for maintenance or due to technical issues.
AI transcription accuracy: While we aim for high-quality transcription, we make no guarantees regarding the accuracy or reliability of automated transcriptions. You should independently review and verify results before relying on them.
Disclaimer of warranties: To the fullest extent permitted by law, the Service is provided on an "as is" and "as available" basis. We disclaim all warranties, whether express or implied, including warranties of merchantability, fitness for a particular purpose, or non-infringement.
9. Limitation of liability
To the maximum extent permitted by applicable law, Leo Technologies Limited (including our officers, directors, employees, and agents) shall not be liable for any indirect, incidental, special, consequential, or exemplary damages, or for any loss of profits, revenues, or data, arising out of or in connection with your use of (or inability to use) the Service.
Our total liability to you for all claims arising out of or relating to these Terms shall be limited to the amount you paid us for your subscription in the 12 months preceding the claim, or £100 GBP if no fees were paid, whichever is greater. Nothing in these Terms shall exclude or limit our liability where it would be illegal to do so.
10. Account termination
By you: You may delete your account at any time, which will remove your personal data from our active systems. However, non-personal copies of your uploaded content (e.g., transcripts) may remain for legitimate business purposes, such as AI model training.
By us: We may suspend or terminate your access to the Service at our discretion, with or without notice, if we believe you have violated these Terms or if we decide to discontinue the Service entirely. If your account is terminated for breach, you will not be entitled to any refund of subscription fees paid.
11. Changes to these terms
We may modify these Terms of Service from time to time. If we make material changes, we will notify you by posting the updated Terms on our website (with a new effective date) and, where appropriate, by email. By continuing to use the Service after such changes become effective, you agree to the revised Terms.
12. Governing law and jurisdiction
These Terms and any dispute or claim arising out of or in connection with them (including non-contractual disputes) shall be governed by and construed in accordance with the laws of England and Wales. You and Leo agree that the courts of England and Wales shall have exclusive jurisdiction to settle any dispute arising out of or relating to these Terms.
Notwithstanding the foregoing, if you are a consumer outside the UK, you may also have the benefit of the mandatory consumer protection laws of your country of residence.
