Terms of Service

These terms govern your use of lemmaro (the “Service”), operated by Andrii Moskaliuk, individual entrepreneur (ФОП) based in Ukraine — see the Legal Notice for full operator details (“we”, “us”). By installing or using the Service, you agree to these terms. If you don't agree, don't use the Service.

The Service

lemmaro is a browser extension and related web service for learning vocabulary while you read. We may add, change, or remove features over time. Some features require an account; some require a paid (“Pro”) plan.

Accounts

You're responsible for keeping your account credentials secure and for activity under your account. You must be at least 13 years old, or the minimum digital-consent age in your country if it is higher, to use the Service. You may create an account with an email and password or via “Sign in with Google”.

Subscriptions, payment & refunds

Paid plans are sold and billed through our merchant of record, Paddle, which also handles taxes and invoicing. Prices, billing intervals, and what each plan includes are shown at checkout. Subscriptions renew automatically at the end of each billing period until you cancel.

You can cancel at any time from your account or billing portal. When you cancel, your Pro access continues until the end of the period you've already paid for, and you are not charged again. We do not provide pro-rated refunds for the unused part of a billing period unless required by law. Where mandatory consumer law gives you a statutory right of withdrawal, refund, cancellation, or other remedy, that right still applies and is honoured.

Dictionary, AI, and learning content

Definitions, translations, examples, exercises, and AI-generated content are learning aids. We try to make them useful, but they may be incomplete or wrong. Do not rely on them for medical, legal, financial, immigration, or other high-stakes decisions.

Acceptable use

You agree not to:

• break the law or infringe others' rights while using the Service;
• reverse-engineer, scrape, resell, or abuse the Service or its APIs beyond what these terms allow;
• attempt to disrupt, overload, or gain unauthorised access to the Service.

Intellectual property

The Service, including its software, dictionary and sense data, and branding, is owned by us or our licensors and is protected by law. We grant you a personal, non-exclusive, non-transferable licence to use the Service under these terms. You keep ownership of the content you create, such as saved words and notes.

Your content and reading context

You are responsible for the text, notes, and other content you choose to process with lemmaro. You grant us only the limited permission needed to provide the Service, such as syncing saved words or returning a lookup for a sentence you send to the backend.

Disclaimers & liability

The Service is provided “as is” and “as available”, without warranties of any kind, to the extent permitted by law. We do not promise that the Service will be uninterrupted, error-free, or available in every country, browser, or website.

To the maximum extent permitted by law, we are not liable for indirect, incidental, or consequential damages, and our total liability for any claim relating to the Service is limited to the amount you paid us in the 12 months before the claim. Nothing in these terms limits liability that cannot be limited by law, including mandatory consumer protections that apply where you live.

Termination

You can stop using the Service at any time, and you can request deletion of your account by emailing hello@lemmaro.com. We may suspend or terminate your access if you materially breach these terms or use the Service unlawfully.

Changes

We may update these terms; we'll post the new version here and update the date above. If a change is material, we'll make reasonable efforts to notify you. Continued use after a change takes effect means you accept the updated terms.

Governing law & contact

These terms are governed by the laws of Ukraine, without prejudice to any mandatory consumer-protection rights you have where you live. Questions? Email hello@lemmaro.com.
