Synti AppsTerms of Service
Last updated: 12 October 2026. Written in the same plain words as the product. If anything here is unclear, that is a fault worth reporting.
What this is
Synti Apps is two applications and a small online service behind them. Synti App Creator turns what you describe into a real application on your own computer, using your own Claude or ChatGPT account. The Synti App Hub is where people find applications others chose to share, and install their own copy. The service holds accounts, subscriptions, the catalogue of shared applications and the record of which versions exist. These terms are the agreement between you and Synti Labs for all of it. Using any part of it means you accept them.
The words used here
"We", "us" and "Synti Labs" mean the maker of Synti Apps. "You" means the person or organisation using it. The "applications" are Synti App Creator and Synti App Hub; the "service" is the online part behind them - accounts, subscriptions, the catalogue and the version record. An "app" is what you make with Synti App Creator. "Publishing" is choosing to put an app in the App Hub: for everyone, for whoever has the link, or for people you name. "Your content" is everything you make, publish or write through Synti Apps - apps, their pages, ratings and notes. These four documents - these terms, the Privacy Policy, the Refund Policy and the AI Content Policy - are one agreement; where they disagree about the same thing, these terms decide, except that the Privacy Policy decides about personal data and the Refund Policy about refunds.
Who may use it
Anyone aged 16 or over, or older where your country requires it, and able to enter a contract. If you pay for a plan you confirm you are 18 or over. You may not use Synti Apps if you are subject to sanctions that forbid it, or in a country to which we are not allowed to supply software. An organisation may use it through a person who accepts these terms on its behalf; that person confirms they may.
Your account
An account exists so that a subscription and what it allows can follow you from one computer to another. You sign in with an email address and a code we send to it: there is no password to lose, and whoever can read that inbox can reach the account, so keep it safe. Tell us at once if you believe somebody else has used your account. One account is for one person; do not share it. We may suspend or close an account that breaks these terms, is used to harm others, or is used to abuse the service, and we will say why unless the law stops us.
What you make is yours
The applications you make are yours: the code, everything you keep in them, and what you do with them. We claim no ownership and take no licence in them, and we never see them unless you publish one. You are responsible for what you make, for checking it does what you need, and for anything you publish or give to somebody else.
The AI is yours too
Synti Apps does not sell, resell or include AI. Applications are made by Claude or ChatGPT running on your own computer with your own account, under your agreement with Anthropic or OpenAI, and whatever that use costs is between you and them. Their terms apply to what you send and what comes back, including their rules about what may be asked for. We are not a party to that, and we never see it.
What you may not do
Do not use Synti Apps to make, publish or distribute anything unlawful; anything designed to damage, deceive or spy on the person who installs it; malware, ransomware, cryptominers or hidden data collection; anything that infringes somebody else's copyright, trade mark, patent, trade secret or privacy; sexual material involving minors, or material that incites violence or hatred. Do not probe, overload or interfere with the service, its rate limits or the checks it runs; do not use it to send unsolicited messages; do not present somebody else's application as your own; and do not impersonate anybody. We may remove content and suspend accounts for any of this.
Publishing to the App Hub
Publishing means other people may find your application and install their own copy. Publishing is a choice you make per application, and you can publish to everyone, to whoever has the link, or to a few people by name. When you publish, you confirm you have the right to do so, that the application is yours to give, and that it does what its page says. You give Synti Labs a non-exclusive, worldwide, royalty-free licence to store your application and its page, to copy and deliver them to people who install it, to show its name, icon, description and screenshots in the catalogue and in our own material about the service, and to make the technical copies delivery needs. That licence lasts while the listing is published, and survives afterwards only for copies already delivered. You may take a listing down at any time; copies people already installed remain theirs, and we cannot recall them.
What the App Hub is, and is not
The App Hub is a place where people share what they made. Applications in it are made and published by their creators, not by us: we do not write them, do not review them line by line, and do not warrant them. Every application declares what it may reach - your files, the internet, the camera - before you install it, and anything it did not ask for is not available to it at all. Treat an application from the App Hub as you would any other software from a stranger: look at what it asks for, and try it before you depend on it. When you install an application, your licence to use it comes from its publisher, not from us, and any dispute about it is between you and them; we will help where we reasonably can.
Blocking and removing what is published
We may, at our sole discretion and at any time, block, unpublish, disable or permanently delete any application, listing, page, rating or note published through Synti Apps, refuse to publish it again, and suspend or close the account behind it. We may do so without notice and without giving a reason in advance, and we are not liable to you or to anybody else for doing it. This applies in particular where we consider that what was published breaks these terms or our policies, infringes anybody's copyright, trade mark, patent, trade secret, privacy or other rights, breaks any law that applies to us or to the person who installs it, or puts people or the service at risk - and it applies whether the complaint comes from a rights holder, an authority, another person or ourselves. We have no duty to monitor what is published and no duty to look for any of this; not acting on one thing does not stop us acting on another. Where we can, we say afterwards what was removed and why, you may reply to us at the address on this page, and if we were wrong we put it back. We may keep a copy of what was removed for as long as we may need it for a complaint or a legal claim. What we cannot do is reach copies already installed on other people's computers: those are theirs, and taking a listing down does not take them back.
Copyright complaints
If something in the App Hub infringes your rights, write to apps@synti.co with: what you own, where it is (the application and its page), enough for us to find it, your contact details, and a statement that you believe in good faith that the use is not permitted and that what you have told us is accurate. We will look at it promptly and remove or disable what is infringing where the complaint is justified. The person who published it may reply, and we will pass their reply on; if the matter is then disputed, it is between the two of you and the law. Accounts that infringe repeatedly are closed.
Ratings and notes
You can rate an application from one to five stars and write a note to whoever made it. Write only what you believe to be true, about the application and not about a person; do not include anybody's personal details, and do not use a rating or a note to abuse, threaten or advertise. A rating is kept against the copy of the application or, if you were signed in, against your account, so rating again changes what you said rather than adding a second voice. The maker of the application can read the notes left on it. We may remove a rating or a note that breaks these terms, and we may remove those left to distort an application's standing.
Subscriptions, prices and renewals
A subscription buys what the applications offer around what you make - it never buys access to what you have already made, and never takes it away. Every paid plan begins with seven days free: the plan works in full from the first day, nothing is charged until the seven days are over, and if you cancel inside them you are not charged at all. After that it renews automatically at the price shown when you subscribed, for the same period, until you cancel; you can cancel at any time, and it then runs to the end of the period you have paid for. Prices can change: a change is announced before it applies and never affects a period you have already paid for. Subscriptions are sold by Polar (polar.sh) as merchant of record on our behalf: Polar is the seller you pay, takes the payment, charges the tax your country asks for, sends the receipt and makes any refund, under its own terms of sale, which you accept when you pay. When a subscription ends, what the plan allowed stops; your applications and everything in them go on exactly as before.
Changes to the service
Synti Apps is developing, and parts of it change. We add things, improve things and sometimes remove something that did not work. If we remove or materially reduce something a paid plan promised, we will say so in advance and, where it matters, refund the part of the period you have paid for. We do not promise that the service is available without interruption, and we may take it down for maintenance or for reasons outside our control. Nothing about an application already on your computer depends on the service being up.
Updates
The applications check for new versions of themselves and of the applications you installed from the App Hub, and offer them; you decide whether to install. Updating an application replaces its code and never its data, and a change that fails leaves what you had exactly as it was.
Our own rights
The Synti Apps applications, the service, this website, our name, our marks and everything we wrote belong to Synti Labs and its licensors. You may use them to use the service and for nothing else: not to copy, resell, rent, reverse engineer beyond what the law allows you, or to build a competing service out of them. Nothing in these terms gives you rights in our marks.
Your feedback
If you send us an idea, a report or a suggestion, we may use it to improve Synti Apps without owing you anything for it. You keep whatever rights you have in it; you simply allow us to act on it.
No warranty
Synti Apps is provided as it is. Software written by an AI can be wrong in ways that are hard to see, and every application is tried out before it reaches you, which catches a great deal and cannot catch everything. To the extent the law allows, we exclude every warranty that is not written here, including warranties of merchantability, fitness for a particular purpose and non-infringement, and we do not promise that the service will be uninterrupted or error-free, or that an application will be fit for any particular use. If you are a consumer, the rights your own law gives you stand whatever this paragraph says.
What we are liable for
To the extent the law allows: we are not liable for indirect or consequential loss, for lost profits, lost business, lost goodwill, or for loss or corruption of data that you could reasonably have avoided by keeping your own backup; and our total liability to you for everything connected with Synti Apps is limited to what you have actually paid us in the twelve months before the claim - so where you have paid us nothing, which is the case for everything Synti Apps gives away free, we have no liability to you at all. Nothing here limits liability for death or personal injury caused by our negligence, for fraud, or for anything else that the law does not let us limit - including, for consumers, the rights the law of your country gives you.
If you cause us a claim
If you publish an application or anything else through Synti Apps, and somebody brings a claim against us because of it - because it infringed their rights, damaged them, or broke the law - you will cover the reasonable cost of dealing with that claim, provided we tell you about it promptly and let you take part in defending it. This does not apply to you as a consumer using Synti Apps privately, except where the claim arises from what you published.
Ending it
You may stop using Synti Apps at any time, and delete your account by writing to us; deleting it cancels any subscription at the end of the period you have paid for. We may end this agreement on notice if you break it seriously, or without notice where the law or somebody's safety requires it. When the agreement ends: everything on your computer keeps working; listings you published are taken down; and the parts of these terms that make sense afterwards - ownership, liability, law - survive.
Changes to these terms
We may change these terms as the service changes or the law requires. A material change is announced on this site, and where you have an account we write to you, at least fourteen days before it applies. If you do not accept a change, stop using the service before it applies and write to us about the part of any subscription you have paid for.
Telling each other things
We write to you at the email address on your account, or say it in the applications or on this site; a notice sent that way counts as given the day it is sent. Write to us at apps@synti.co - that address reaches us for everything, including a formal notice, a complaint about something published, and a request about your own data.
Responsible disclosure
If you find a weakness in Synti Apps, tell us at apps@synti.co before you tell anybody else, and give us a reasonable time to fix it. While you look, stay in your own account and your own data: do not read, change or keep anybody else's, do not degrade the service for others, and do not use the weakness for anything beyond showing that it exists. Report it that way and we will not treat your research as a breach of these terms, and we will thank you by name in the release that fixes it if you would like.
Where we cannot supply
You confirm that you are not in a country, and not a person or organisation, that sanctions or export rules forbid us to supply, and that you will not make Synti Apps available to one. If that changes, stop using it and tell us.
Handing the agreement on
You may not transfer this agreement, or an account, to somebody else without our agreement in writing. We may transfer it to a company that takes over the business that runs Synti Apps, provided your rights under it are unchanged; we will say so before it happens, and you may close your account and ask for the unused part of a subscription back.
Things outside anybody's control
Neither of us is liable for failing to do something because of an event beyond reasonable control - war, a natural event, a failure of the internet or of a provider we depend on, a change in the law. What we can do, we do; what is delayed, we say so about as soon as we can.
The rest of the small print
These four documents are the whole agreement between us about Synti Apps, and they replace anything said before them. Not enforcing something once does not give it up for the future. If a court finds one sentence unenforceable, the rest stands, and that sentence is read as narrowly as it can be while keeping its purpose. Nobody other than you and us has rights under this agreement. Headings are there to help you read, not to change what the paragraphs say. These documents are written in English; a translation is a courtesy, and the English decides.
Which law applies, and where disputes go
These terms are governed by the law of Ukraine, where Synti Apps is made. If you use Synti Apps as a consumer, you also keep every protection the mandatory law of your own country gives you, and nothing here takes it away. If something goes wrong, write to us first: nearly everything is settled that way. If it is not, a dispute goes to the courts of Ukraine, or to the courts of your own country where its law gives you that right. If you are in the European Union, you may also use the European Commission's online dispute resolution platform.
