Terms of Service

Version 2.1. Last updated 2 September 2026. Effective on publication.

These Terms of Service (the “Terms”) constitute a binding legal agreement between you (“you”, “your”, the “Customer” or the “User”) and Lev, an individual sole proprietor trading as ThatLev (“the Provider”, “I”, “me” or “my”), governing your access to and use of the websites operated at thatlev.com and stillon.dev, together with each subdomain, page and application programming interface made available through them (collectively, the “Site”), and your download, installation, activation and use of the StillOn software application for macOS, including all updates, builds, pre-release and beta versions of it (the “Software”, and together with the Site, the “Services”).

Please read section 7 and section 9 carefully. Section 7 provides a 14-day money-back guarantee and explains what happens to a refunded licence. Section 9 limits my aggregate liability to you and excludes several categories of loss entirely. Section 12 governs the resolution of disputes. These provisions apply except to the extent that mandatory law where you reside provides otherwise.

1. Acceptance, capacity and formation of the agreement

By accessing the Site, downloading or installing the Software, activating a licence key, initiating a checkout, or otherwise using any part of the Services, you acknowledge that you have read, understood and agreed to be bound by these Terms and by the Privacy Policy and Refund Policy incorporated by reference into them. If you do not agree to any provision of these Terms in its entirety, you must not access the Site, must not install or use the Software, and must not complete a purchase.

You represent and warrant that you are at least eighteen (18) years of age, or the age of legal majority in your jurisdiction of residence if that age is greater, and that you possess the legal capacity to enter into a binding contract. Where you accept these Terms on behalf of a company, partnership, institution or other legal entity, you further represent and warrant that you hold the authority to bind that entity, in which case “you” refers to that entity and its authorised personnel.

A contract of sale is formed at the moment a payment authorisation is accepted by the payment processor and a licence key is generated for delivery to the address supplied at checkout, and not before. My display of a price, offer, discount or promotional code constitutes an invitation to treat and not a binding offer capable of acceptance.

2. Nature of the Site and status of unreleased projects

The Site is a personal index of software projects in varying states of completion. The status indicator displayed beside each project denotes its condition at the time of publication and is provided for information only. A project described as unreleased, planned, in progress or in beta may be altered in scope or specification, delayed indefinitely, withdrawn, renamed, merged into another project, or abandoned without notice, without liability, and without any obligation to publish an explanation.

Registering interest in an unreleased project, including by joining an email-backed launch list, creates no contractual right of any kind. It is not a purchase, not a pre-order, not a deposit, not a reservation, not an option, and not a promise that the project will be built, released, priced in any particular way, or made available in your territory.

Forward-looking statements published on the Site, including roadmaps, timelines, intended features and expected release windows, reflect present intention only. They are not commitments, are not warranted, and may be revised or abandoned at any time.

3. Licence grant, scope and permitted use

Subject to your continuing compliance with these Terms and to payment of all applicable fees, I grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable licence to install and use the Software in object-code form for its intended purpose (the “Licence”). The Licence is granted, not sold. All right, title and interest in and to the Software, including every copy, modification, enhancement, derivative work and update of it, remains with me and my licensors at all times.

A single Licence is issued to one identified customer and may be simultaneously activated on up to three (3) supported Macs owned or controlled by that customer. You may release an activation and reassign it to a replacement machine using the secure management facility associated with the email address supplied at checkout. Activation capacity is a technical limit on concurrent installations and is neither a quantity of goods nor a divisible entitlement capable of separate resale.

A licence described as a lifetime licence entitles you to use the version of the Software current at the date of purchase and such subsequent versions as I elect, in my sole discretion, to make available to existing licence holders. “Lifetime” refers to the commercial lifetime of the Software as a product offered by me. It does not denote your natural lifetime, does not create a perpetual obligation to develop, publish, host, support or maintain the Software, and does not guarantee compatibility with any future version of macOS or any future Apple hardware.

4. Restrictions

You shall not, and shall not permit or enable any third party to:

• reproduce, publish, distribute, rent, lease, lend, sell, resell, sublicense, assign, transfer, time-share, or otherwise make the Software or any licence key available to any third party, whether or not for charge;
• disclose, publish or expose any licence key, activation credential or management link to the public or to any person other than yourself;
• reverse engineer, decompile, disassemble, decrypt, or otherwise attempt to derive the source code, underlying ideas, algorithms, file formats, protocols or internal structure of the Software, except and only to the precise extent that such an act is expressly permitted by applicable law notwithstanding this prohibition, and then only after prior written notice to me;
• modify, adapt, translate or create derivative works of the Software, or remove, obscure or alter any proprietary notice, mark or attribution contained in it;
• circumvent, disable, tamper with or defeat any licensing, activation, entitlement, integrity or security mechanism of the Services, or use any key obtained other than through a completed purchase from me;
• access the Services by automated means, including scraping, crawling or harvesting, or transmit any malware, or impose an unreasonable or disproportionate load on my infrastructure, or probe, scan or test the vulnerability of any system or network without my prior written authorisation;
• use the Services in violation of any applicable law, including export control, sanctions, data protection and anti-corruption law, or for the benefit of any person or territory subject to comprehensive sanctions.

Each restriction in this section is a material term. I reserve the right to suspend or terminate any Licence, and to invalidate any key, upon a reasonable determination that this section has been breached.

5. Operating requirements, trial and beta software

The Software requires an Apple-silicon or Intel Mac running macOS 13 or later. It is your responsibility to verify compatibility before purchase. A free evaluation period is made available so that compatibility and suitability can be established at no cost, and the availability of that evaluation period is a material element of the commercial terms set out in section 7.

Software identified as beta or pre-release is supplied for evaluation and may contain defects, may behave unpredictably, and is furnished without any warranty whatsoever. It may be modified or withdrawn at any time. You assume the entire risk arising from use of pre-release Software.

The Software assists with power-management behaviour on a Mac. It does not, and cannot, guarantee that any particular task, process, download, build, transfer, session or automation will begin, continue or complete. Outcomes depend on hardware condition, thermal environment, battery state, network availability, operating-system behaviour, third-party software, and configuration outside my control. Any optional protective behaviour offered in the Software is a convenience measure, is not a safety system, is not a substitute for prudent handling of your hardware, and must not be relied upon as one.

6. Fees, taxes and payment processing

Prices are stated in the currency shown at checkout and, unless expressly indicated otherwise, exclude value added tax, goods and services tax, sales tax, and any other levy, duty or withholding, which shall be added where required and borne by you. Payments are collected by a third-party payment processor, and your use of the checkout is additionally subject to that processor’s own terms. I do not receive, handle or store complete payment-card details.

Promotional pricing is valid only for the period stated and may be withdrawn at any time before a contract of sale is formed. Prices may be revised prospectively; a revision does not entitle an existing licence holder to a rebate, credit or price adjustment.

You are responsible for supplying an accurate email address you control and for maintaining access to it. Delivery of a licence key to the address supplied at checkout constitutes delivery of the Licence in full. I bear no responsibility for non-receipt caused by an incorrect address, a full mailbox, or filtering by your mail provider, though I will re-send a key on request following reasonable verification.

7. 14-day money-back guarantee

Every StillOn purchase has a 14-day money-back guarantee. If StillOn is not right for you, email hello@stillon.dev within 14 days of purchase and I will refund the amount you paid in full, for any reason.

The guarantee runs from the purchase date, separately from the free evaluation period. It applies whether or not you used the trial, activated the key, installed the Software, changed your mind, or found the Software unsuitable. The request must be sent from the checkout email address or include enough receipt or order information to identify the purchase. The refund is made to the original payment method and is limited to the amount actually paid.

A full refund terminates the Licence and permanently disables the associated key. You must stop using and remove copies activated with that key. Requests after 14 days are at my discretion and may be declined, except where applicable law requires a remedy. I may decline a request that is fraudulent or clearly abusive.

This guarantee is additional to, and does not exclude, restrict or modify, any guarantee, right or remedy that applicable consumer law confers and that cannot lawfully be excluded, restricted or modified. The complete process is set out in the Refund Policy, which forms part of these Terms.

Contact me before opening a chargeback or payment dispute, as a direct refund is normally faster. A licence may be disabled while its payment is disputed and will be permanently disabled if the payment reversal becomes final.

8. Disclaimer of warranties

To the maximum extent permitted by applicable law, the Services are provided “as is” and “as available”, with all faults and without warranty of any kind. I expressly disclaim all warranties, conditions, representations and terms, whether express, implied, statutory or arising from a course of dealing or usage of trade, including any implied warranty of merchantability, satisfactory quality, fitness for a particular purpose, title, quiet enjoyment, accuracy, and non-infringement.

Without limiting the foregoing, I do not warrant that the Services will be uninterrupted, timely, secure or error-free; that defects will be corrected; that the Services will operate with any particular hardware, operating-system version or third-party software; or that any result, saving, outcome or level of performance will be achieved. No advice or information, whether oral or written, obtained from me or through the Services creates any warranty not expressly stated in these Terms.

9. Limitation of liability

To the maximum extent permitted by applicable law, in no event shall I be liable for any indirect, incidental, special, consequential, exemplary or punitive damages, nor for any loss of profits, revenue, goodwill, business opportunity, anticipated savings, or wasted expenditure, nor for any loss, corruption or inability to recover data, nor for any damage to, degradation of, or reduction in the service life of any hardware, battery or component, nor for any interruption, failure, delay or non-completion of any task, build, download, transfer, session, automation or process, howsoever caused and on any theory of liability, whether in contract, tort (including negligence), strict liability or otherwise, and whether or not I have been advised of the possibility of such damages.

To the maximum extent permitted by applicable law, my total aggregate liability arising out of or relating to these Terms or the Services, from all causes of action and under all theories of liability, shall not exceed the greater of (a) the total amount you actually paid to me for the Licence in the twelve (12) months preceding the event giving rise to the claim, and (b) fifty United States dollars (USD 50).

Nothing in these Terms excludes or limits my liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot lawfully be excluded or limited. The limitations in this section apply notwithstanding the failure of the essential purpose of any limited remedy, and reflect a reasonable allocation of risk that forms an essential basis of the bargain between us; the price charged would be materially higher in their absence.

10. Indemnity

You shall indemnify, defend and hold me harmless from and against any claim, demand, proceeding, loss, liability, damage, cost and expense, including reasonable legal fees, arising out of or relating to your use or misuse of the Services, your breach of these Terms, your violation of any applicable law, or your infringement of the rights of any third party.

11. Term, suspension and termination

These Terms take effect on your first use of the Services and continue until terminated. You may terminate at any time by ceasing all use of the Services and removing all copies of the Software. I may suspend or terminate your access, and invalidate any licence key, immediately and without notice, where I reasonably determine that you have materially breached these Terms, that a payment has been reversed, charged back or otherwise not honoured, or that continued provision would expose me to legal or security risk.

Termination for breach does not itself create a right to a refund, but it does not remove a refund otherwise available under section 7 or mandatory law. Sections 4, 7, 8, 9, 10, 12 and 13, together with every other provision that by its nature should survive, survive termination.

I may modify, suspend or discontinue any part of the Services, in whole or in part, at any time. Where a discontinuation would materially and permanently deprive existing licence holders of the core functionality of the Software, I will endeavour to give reasonable prior notice by email, but I assume no liability for any discontinuation.

12. Governing law and dispute resolution

These Terms and any non-contractual obligation arising out of or in connection with them are governed by the laws of the Republic of Cyprus, without regard to its conflict of laws rules and excluding the United Nations Convention on Contracts for the International Sale of Goods. The courts of the Republic of Cyprus shall have exclusive jurisdiction over any dispute arising out of or in connection with these Terms.

Where you contract as a consumer, this section does not deprive you of the protection of the mandatory provisions of the law of your country of habitual residence, nor of any right you may have to bring proceedings in the courts of that country. Consumers resident in the European Union may also access the European Commission’s online dispute resolution platform.

Before commencing any proceeding, you agree to contact me in writing and to allow a period of thirty (30) days for good-faith resolution of the matter. Any claim must be brought in an individual capacity and not as a plaintiff or class member in any purported class, collective, consolidated or representative proceeding.

13. Intellectual property, third-party marks and comparisons

The Site, the Software, and all text, layout, design, imagery, footage, structure and compilation contained in them are protected by copyright and other intellectual property rights and remain my property or that of my licensors. No right or licence is granted except as expressly stated in these Terms. Where an individual project is published under its own open-source or other licence, that licence governs that project to the extent of any inconsistency with these Terms.

Product names, marks and logos belonging to third parties, including those of artificial intelligence and developer tools referenced on the Site, remain the property of their respective owners and are used solely for nominative, descriptive and interoperability purposes to identify software with which the Software is commonly used. Their use does not imply, and must not be taken to imply, any affiliation with, sponsorship by, endorsement by, partnership with, or certification by those owners, and no such relationship exists.

Where a price of a category of hardware or software is referenced, it represents my own estimate of a typical market price at the time of writing, given for illustrative comparison only. It is not a statement of fact about any identified company’s product, is not warranted as accurate or current, and must not be relied upon for any purchasing decision.

14. Communications and email

You must supply a genuine email address that you control. Transactional messages relating to a purchase, a licence key, a security event or a management request are a necessary part of the Services and cannot be declined while a Licence remains active. Optional product-update messages may be discontinued at any time on request.

15. General provisions

These Terms, together with the Privacy Policy and the Refund Policy, constitute the entire agreement between us in respect of their subject matter and supersede all prior understandings, whether written or oral. If any provision is held invalid, illegal or unenforceable, it shall be modified to the minimum extent necessary to render it enforceable, or, if modification is not possible, severed; the remaining provisions continue in full force.

No failure or delay in exercising any right operates as a waiver of it. You may not assign or transfer these Terms or any Licence without my prior written consent; I may assign them freely, including in connection with a transfer of the business or assets to which they relate. Nothing in these Terms creates a partnership, joint venture, agency or employment relationship. There are no third-party beneficiaries. I am not liable for any failure or delay in performance caused by circumstances beyond my reasonable control.

I may amend these Terms at any time by publishing a revised version bearing a new effective date. Amendments apply prospectively. Your continued use of the Services after the effective date constitutes acceptance of the revised Terms. Where an amendment materially reduces the rights of existing licence holders, I will endeavour to give notice by email to the address associated with the Licence. These Terms are drafted in English; any translation is provided for convenience and the English version prevails.
