Terms of Use
Last updated: 14 May 2026
1. Who these terms are with
These Terms of Use form a binding agreement between you and CurrentLabs B.V., a private limited company registered in the Netherlands (Dutch Chamber of Commerce KvK 99541122, VAT NL869032653B01), with its registered office at Borneostraat 96E, 1094 CR, Amsterdam, the Netherlands. References to "we", "us", or "CurrentLabs" mean that entity.
2. Acceptance
By creating a Leo account, installing the Leo macOS application, or using the https://leonotepad.com website, you agree to these terms and to the Privacy Policy. You must be at least 16 years old to use Leo. If you are using Leo on behalf of an organisation, you confirm that you have the authority to bind that organisation to these terms.
3. The service
Leo is a macOS application for capturing, organising, and exploring personal reference material, with an integrated AI assistant. The application is distributed as a notarised direct download from https://leonotepad.com and is not available through the Mac App Store. We may add, change, or remove features. We will not knowingly remove or materially degrade features you have paid for during the term you have paid for them.
4. Your account
To use Leo's syncing and AI features you create an account by signing in with Apple, Google, or an email/password combination. You are responsible for keeping your credentials confidential and for activity that takes place under your account. Notify us promptly at support@currentlabs.tech if you believe your account has been accessed without your authorisation.
5. Plans, payments, and trial
Leo offers a Free plan, paid subscription plans, and a Lifetime plan, with pricing shown at https://leonotepad.com/pricing. New accounts receive a complimentary one-week Pro trial; no payment method is required to start the trial, and access automatically returns to the Free plan when the trial ends unless you have started a paid subscription.
Merchant of record. All payments are processed by Lemon Squeezy (Lemon Squeezy LLC, United States), which acts as the merchant of record for sales of Leo. Lemon Squeezy is responsible for collecting and remitting applicable sales tax and VAT, issuing receipts, and managing payment-method information. Lemon Squeezy's own terms apply to the payment transaction; those terms are available at lemonsqueezy.com/legal/terms-of-service.
Subscription renewals. Paid subscriptions renew automatically at the end of each billing period unless cancelled before the renewal date. You can manage or cancel your subscription at any time from the Lemon Squeezy customer portal, accessible from within the Leo app.
EU cooling-off period. If you are a consumer resident in the European Union, you generally have a 14-day right of withdrawal from a distance contract for digital services. By starting to use Leo's paid features during the cooling-off period you expressly consent to immediate performance and acknowledge that the withdrawal right is lost once performance has begun, as permitted under Article 16(m) of EU Directive 2011/83/EU. Where the right of withdrawal applies, contact support@currentlabs.tech and we will coordinate the refund with Lemon Squeezy.
6. Refunds
Beyond any statutory rights, refund handling is administered by Lemon Squeezy under their standard policy. Requests submitted within Lemon Squeezy's refund window for a given product are generally honoured; requests beyond that window are considered case-by-case. To request a refund, contact support@currentlabs.tech with your order ID.
7. Your content
The notes, captured material, prompts, and other content you create or save in Leo ("Your Content") remain yours. You retain all rights, title, and interest in Your Content; we claim no ownership of it. You grant CurrentLabs a limited, non-exclusive, worldwide, royalty-free licence to host, store, transmit, display, and process Your Content for the sole purpose of operating Leo and providing the service to you (for example, syncing your notes between devices, indexing them for in-app search, or passing them to the AI assistant when you initiate an AI request). This licence terminates when Your Content is deleted, except where we are required to retain a copy by law.
8. AI features
Leo's AI features are powered by third-party large language models. Depending on the feature you use, prompts and relevant conversation context are forwarded to one of the following providers:
- Anthropic Claude, accessed via our own server-side proxy. Used for the conversational AI assistant. Anthropic states it does not train on customer API traffic.
- Google Gemini, accessed via Firebase AI Logic with the Google AI backend. Used for background pipeline tasks such as summarisation and source extraction. Under Google's paid-tier Gemini API terms, prompts and responses are not used to train Google's models.
Both providers process requests on US-based infrastructure. The resulting conversation is stored in your Leo account.
AI output is not always accurate. Large language models can produce information that is incomplete, out of date, or factually wrong ("hallucinations"). Leo's AI output is provided for informational and productivity purposes only; it is not legal, financial, medical, or other professional advice. Verify anything you intend to rely on before acting on it. You are responsible for how you use AI output, including ensuring that you have the right to share any source material you ask the AI to process and that your use complies with applicable law.
9. Acceptable use
You may not use Leo to:
- Violate any applicable law, regulation, or third-party right (including intellectual-property rights);
- Upload, store, transmit, or process content that is unlawful, defamatory, harassing, sexually explicit involving minors, or that infringes another person's rights;
- Send malware, attempt to gain unauthorised access to our systems or other users' accounts, or interfere with the integrity, performance, or availability of the service;
- Reverse-engineer, decompile, or attempt to extract source code or model weights from Leo or its dependencies, except to the extent this restriction is prohibited by applicable law;
- Resell, sublicense, or commercially redistribute access to Leo or to the AI features without our prior written agreement;
- Use the AI assistant to generate output for unlawful purposes, including the targeted harassment of identifiable individuals, the generation of synthetic media intended to deceive, or any use prohibited by the underlying model provider's policies.
We may suspend or terminate access for users who breach this section, with or without notice depending on the severity of the breach.
10. Intellectual property
The Leo application, the https://leonotepad.com website, and the CurrentLabs name and logo are the property of CurrentLabs B.V. or its licensors and are protected by Dutch and international copyright, trademark, and other intellectual-property laws. Nothing in these terms grants you any right or licence to those properties beyond the limited right to use Leo as expressly permitted here.
11. Disclaimer of warranties
To the maximum extent permitted by law, Leo is provided "as is" and "as available", without warranty of any kind — express, implied, or statutory — including warranties of merchantability, fitness for a particular purpose, non-infringement, or that the service will be uninterrupted, error-free, or secure. We do not warrant that AI output will be accurate, complete, or fit for any particular purpose. This section does not exclude or limit any warranty that cannot be excluded under applicable consumer-protection law.
12. Limitation of liability
To the maximum extent permitted by law, CurrentLabs is not liable for any indirect, incidental, special, consequential, or punitive damages — including loss of profit, loss of business, loss of data, or loss of goodwill — arising out of or in connection with Leo or these terms. Our total cumulative liability arising out of or relating to Leo is capped at the greater of (a) the amount you have paid CurrentLabs for Leo in the twelve months preceding the event giving rise to the liability, or (b) €100. Nothing in these terms limits liability that cannot be limited by law, including liability for death or personal injury caused by negligence, fraud, or any other liability that mandatory Dutch consumer law preserves for consumers.
13. Termination
You may terminate your account at any time from within the Leo application. On termination, your data is hard-deleted within 30 days, except where retention is required by law. We may terminate or suspend your access if you materially breach these terms, if your use creates a legal or security risk to us or to other users, or if we are required to do so by law. Sections that by their nature should survive termination (intellectual property, disclaimers, limitation of liability, governing law) do survive.
14. Changes to these terms
We may revise these terms from time to time. The "Last updated" date at the top of this page reflects the most recent revision. We will give you at least 30 days' advance notice of material changes through the app or by email (where we have your address), except where an earlier change is required by law. Continued use of Leo after a revision takes effect constitutes acceptance of the revised terms.
15. Governing law and jurisdiction
These terms and any dispute arising from them are governed by the laws of the Netherlands, excluding its rules on conflict of laws. The competent courts of Amsterdam, the Netherlands, have exclusive jurisdiction over any dispute arising from these terms, except that consumers retain the right to bring proceedings in the courts of their own country of residence where mandatory consumer-protection law so provides. The United Nations Convention on Contracts for the International Sale of Goods does not apply.
16. Miscellaneous
If any provision of these terms is found unenforceable, the remaining provisions remain in effect. Our failure to enforce any provision is not a waiver of that provision. You may not assign these terms without our prior written consent; we may assign them to a successor in connection with a merger, acquisition, or sale of substantially all our assets. These terms (together with the Privacy Policy and any policies they reference) form the entire agreement between you and CurrentLabs in respect of Leo and supersede any prior agreements on the same subject matter.
