Terms of sale and licence

LeoNote desktop application and the leonote.app website · Last updated: 17 September 2026

1. Who we are, and what these terms cover

“LeoNote” is a desktop application published by Olexify (“we”, “us”), an independent developer currently established in Ukraine. Contact: olexifyyy@gmail.com.

These terms cover your purchase of LeoNote, your use of the application, and your use of the website leonote.app. By buying, downloading, installing or using LeoNote you agree to them. If you do not agree, do not buy or use LeoNote; if you already bought it, section 4 explains how to get a refund.

You must be old enough to enter into a binding contract where you live, or have the consent of a parent or guardian who accepts these terms for you.

2. Buying LeoNote

Who sells it to you. Payment is handled by the payment provider or store shown at checkout. Where that provider acts as reseller or “merchant of record”, or where you buy through a store such as Steam, that provider or store is the seller of record: it takes your payment, charges any applicable tax, issues your receipt, and its own terms and refund rules apply to the transaction alongside these terms. We never receive or store your card details.

Price and tax. Prices are shown before you pay. VAT, sales tax or similar charges may be added depending on where you are. Launch prices, discounts and regular prices may change at any time; a change never affects a purchase already made.

Delivery. LeoNote is a digital product delivered by download. It is delivered when the download or licence is made available to you.

3. What your purchase includes

• A licence to the current version of LeoNote and to every update we release within the same major version (all “1.x” releases for a 1.0 purchase).
• Use on all the computers you personally own or personally use.

What it does not include. Your purchase is for the application as it exists when you buy it. Anything described on the website, in the app or elsewhere as planned, coming, “later” or “soon” — including, without limitation, versions for other operating systems, a mobile app, hosted backup (“LeoNote Cloud”), and further AI-agent features — is a statement of intention, not a promise, and is not part of what you paid for. Such features may change, arrive late, be sold separately, or never ship. Please buy LeoNote for what it does today.

We may release a new major version as a separate, paid product. Your existing version keeps working under these terms. We are not obliged to provide updates, fixes or support for any particular period, although we intend to.

4. Refunds

If you bought LeoNote through leonote.app, you may ask for a full refund within 14 days of purchase, for any reason or none. Write to olexifyyy@gmail.com from the email address you bought with, or use the refund link on your receipt. The refund goes back to the original payment method, and your licence ends when it is issued.

If you bought LeoNote through a third-party store (for example Steam), that store’s refund policy and process apply, and the refund has to be requested there.

We may refuse repeated purchase-and-refund cycles by the same person. Nothing in this section limits any right to withdraw, or any remedy for a faulty product, that the consumer law of your country gives you.

5. Your licence

LeoNote is licensed, not sold. When you buy it you receive a personal, worldwide, non-exclusive, non-transferable, revocable licence to install and use it, for your own personal or internal business purposes, on the computers you own or personally use. One purchase is for one person. An organisation needs one purchase per person using it.

You may not, and may not allow anyone else to:

• copy, distribute, publish, share or make LeoNote, its installer or any licence key available to others, other than installing it on your own computers;
• sell, resell, rent, lease, lend or sublicense it;
• modify it, create derivative works from it, or reverse engineer, decompile or disassemble it, except to the limited extent that applicable law expressly allows despite this restriction;
• remove, bypass or tamper with any licence check, notice or technical protection;
• use LeoNote, its code, design or assets to build, train or publish a competing product;
• use it in breach of any law, or of export-control or sanctions rules that apply to you.

The fact that parts of an installed application are readable on your disk does not place them in the public domain and grants no licence to reuse them. All rights not expressly granted here are reserved by Olexify.

Third-party components. LeoNote includes open-source components under their own licences, listed in the third-party notices shipped with the application. Those licences prevail for those components, and nothing here limits the rights they give you.

6. Your data and your content

It stays with you. LeoNote has no accounts and no servers of ours in the loop. Your notes, tasks, boards, sketches, documents and media are files on your own computer. We do not receive, see, or hold any of them. The Privacy Policy describes this in full.

So backups are yours to keep. Because we never have your data, we cannot restore it. LeoNote creates, edits, renames, moves, converts and deletes files in the folders you point it at — including rewriting links when a note is renamed, re-encoding pasted pictures, compressing video on request, and editing text documents and spreadsheets in place. Software has bugs, disks fail, and sync tools conflict. You are responsible for keeping independent backups of anything you cannot afford to lose, particularly before editing important office documents, which may not preserve every feature of the original file.

Encrypted backups. Backup files made by LeoNote are encrypted with a password only you know. It is never stored or sent anywhere. If you lose it, the backup cannot be opened by anyone, including us.

Your content is your responsibility. You are solely responsible for what you create, store, open, play or share using LeoNote, and for having the right to do so.

7. Third-party files, media, services and AI agents

LeoNote is a tool. It hosts no media, supplies no copyrighted content of its own, and operates no online service that content passes through. Whatever it opens or plays comes from files you provide or from addresses you give it.

Online content. If you give LeoNote a link to something on the internet, the request is made from your computer directly to that third party, as it would be from a web browser. We do not control those services, are not affiliated with them, and do not guarantee that any of them will work with LeoNote, keep working, or be presented in any particular way. You are responsible for having the right to access that material and for complying with the terms of the sites and services you choose to use LeoNote with.

File formats. Support for third-party formats (such as office documents, PDFs, canvas and drawing files, and note folders made by other applications) is provided on a best-effort basis. Formats change, and compatibility is not guaranteed.

AI agents. LeoNote lets external software, including AI agents that you install and run yourself, read and change your notes and tasks. Those agents are not ours. We do not supply, control, supervise or endorse them, and we are not responsible for anything they read, write, change, delete, send elsewhere or get wrong. What an agent may access, which provider it sends your data to, and what that costs you are matters between you and the agent’s provider. Review what agents do, and keep backups.

8. What LeoNote is not for

LeoNote is a general-purpose productivity tool. Reminders, recurring tasks, timers and habit tracking are conveniences and may fail to fire, for example when the computer is asleep or the app is closed. Do not rely on LeoNote as the only safeguard for anything where a missed reminder or lost note could cause injury, serious financial loss or legal consequences, such as medication schedules, legal deadlines or safety-critical work. Nothing in LeoNote is medical, legal, financial or other professional advice.

9. No warranty

To the maximum extent permitted by applicable law, LeoNote and this website are provided “as is” and “as available”, without warranty of any kind, express or implied, including the implied warranties of merchantability, fitness for a particular purpose, title and non-infringement. We do not warrant that LeoNote will be error-free, uninterrupted, secure, compatible with your system or other software, or that it will meet your requirements, or that any file it writes will be readable by any other program. Figures on the website about size, memory use or speed describe our own measurements on our own machines and will differ on yours. No advice or information from us creates a warranty not stated here.

10. Limitation of liability

To the maximum extent permitted by applicable law, Olexify is not liable for any indirect, incidental, special, consequential, exemplary or punitive damages, nor for any loss of or damage to data or files, loss of profits, revenue, business, goodwill or savings, cost of substitute software, or interruption of work or study, arising out of or in connection with LeoNote, this website or these terms, whether the claim is founded in contract, tort (including negligence), statute or otherwise, and even if the possibility of such damage was known.

Where liability cannot lawfully be excluded, our total liability for all claims together is limited to the amount you actually paid for LeoNote.

Nothing in these terms excludes or limits liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, for intent or gross negligence where the law does not allow it to be limited, or for anything else that applicable law does not allow to be excluded or limited. If you are a consumer, these terms do not affect your statutory rights.

11. If your use causes a claim against us

If you use LeoNote for business purposes, you agree to indemnify Olexify against third-party claims, and the reasonable costs of dealing with them, that arise from your content, your breach of these terms, or your use of LeoNote in violation of the law or of someone else’s rights. This section does not apply to consumers where the law does not permit it.

12. Ending the licence

You can stop using LeoNote at any time by uninstalling it. Your licence ends automatically, without notice, if you materially breach section 5, or when a refund or chargeback is issued for your purchase. When the licence ends you must stop using LeoNote and delete your copies. Your own files are unaffected and remain yours; sections 5 to 11 and 13 to 15 continue to apply.

13. Names and trademarks

“LeoNote”, “Olexify”, the LeoNote icon and the design of the application and this website belong to Olexify. Every third-party product, format or company name mentioned on this website or in the application are trademarks of their respective owners, used only to describe compatibility. LeoNote is an independent product and is not affiliated with, endorsed by or sponsored by any of them.

14. This website

The website is provided for information. The application window shown on the home page is an illustration drawn for the page; the real application may look and behave differently, and its features change between versions. We try to keep the site accurate but do not guarantee that it is complete, current or free of errors. Links to other sites are provided for convenience; we are not responsible for them.

15. General

Changes. We may update these terms, for example when the way LeoNote is sold changes. The version in force when you bought LeoNote continues to govern that purchase, unless the change is required by law or is to your benefit. Continuing to use a new version of LeoNote after an update to these terms means you accept the updated terms for that version.

Transfer. We may transfer our rights and obligations under these terms to a company we establish or to a successor of the LeoNote business, including in another country, provided your rights under these terms are not reduced. You may not transfer yours without our written consent.

Events beyond our control. We are not liable for any failure or delay caused by events beyond our reasonable control, including war, hostilities, power or network outages, and acts of government.

Governing law and disputes. These terms are governed by the law of the country in which Olexify is established at the time of your purchase, which is currently Ukraine, without regard to conflict-of-law rules. The courts of that country have jurisdiction. If you are a consumer, you also keep the protection of the mandatory laws of the country where you live, and you may bring proceedings in your own courts. Please write to us first; most things can be fixed with an email.

The rest. If any part of these terms is found unenforceable, that part is limited to the minimum extent necessary and the rest stays in force. Our not enforcing a right is not a waiver of it. These terms, together with the Privacy Policy and the licence file shipped with the application, are the entire agreement between you and us about LeoNote. These terms are written in English; if a translation differs, the English text prevails, unless the law where you live says otherwise.
