Kvinta/ Terms of Use
Kvinta Terms of Use
Effective 13 November 2026.
These terms are an agreement between you and Vivienne Fosh, doing business as LanternApps, a sole proprietorship in Charlottesville, Virginia, USA (“we”, “us”). Postal address: 2105 Bond St, Apt 705, Charlottesville, VA 22901, USA. By using Kvinta you agree to them.
The service
Kvinta writes documents, answers questions and creates images and audio from your requests using AI models. It can search public sources and work from material you provide. Results can be wrong, incomplete, outdated or unsuitable: check them before you rely on them or publish them. A citation shows where a claim comes from; it does not guarantee that the claim is true, and generated content may not be unique.
Answers about medical, legal, financial or tax matters are information, not professional advice. Ask a qualified professional before a decision that matters. Kvinta is not an emergency service: in an emergency, contact your local emergency services instead of waiting for an answer.
The Privacy Policy explains how we handle personal data and the app’s AI permission. The EULA governs the licence to the app itself.
Your account
You need an account, and you must be at least 13 years old (16 in the EU). If you cannot enter a binding contract alone where you live, a parent or guardian must agree to these terms and authorise any purchase. Give an email address you can receive mail at, keep your sign-in to yourself, and tell us if you think someone else has used your account.
You can delete your account at any time: in the app (Settings, then Delete account), or with the form at kvinta.ai/delete-account, which we complete within 30 days. Save what you need first. Deleting the account or uninstalling the app does not cancel a subscription.
Subscriptions and top-ups
Where you buy. On iPhone, iPad and Android you buy in the Apple App Store or Google Play. On a computer you buy through our web checkout, run by RevenueCat (RevenueCat Web Billing), with card payments processed by Stripe. The store or checkout shows the price, the currency, any taxes and the billing period before you pay, and your account shows your balance.
Plans. A plan is a monthly subscription that renews automatically every month until you cancel. Each billing period includes a usage allowance; allowance you do not use does not carry over, and usage beyond it is never charged automatically. Usage depends on what you ask for: an allowance is not a promise of a number of answers or documents. Credits are service usage, not money: they cannot be transferred, withdrawn or exchanged for cash.
Top-ups. Subscribers can buy a top-up (US$10 in our price list; the store or checkout shows the price you pay). A top-up is a one-time, consumable purchase, not a subscription, and never renews. Its usage is spent after the period’s allowance and stays on your account until it is spent, refunded or the account is deleted. It can be used only while you have an active subscription; unrefunded top-up usage becomes available again when you subscribe again.
Managing and cancelling. In Kvinta, open Settings and tap Manage subscription: on a phone or tablet it opens your App Store or Google Play subscriptions; on a computer it opens the billing page of your web purchase. You can also cancel an Apple purchase in your App Store subscription settings, a Google Play purchase in Google Play, and a web purchase by writing to support@kvinta.ai. Cancel before the next renewal, and follow the store’s own deadline. Cancelling stops future renewals; you keep access until the end of the period you paid for, unless the purchase is refunded or access ends under these terms. Cancelling does not remove top-up usage you have not used.
Refunds and withdrawal
- App Store purchases: Apple decides refunds under its own rules. Request one at reportaproblem.apple.com.
- Google Play purchases: refunds follow Google Play’s refund policies. Request one in Google Play, or write to support@kvinta.ai.
- Web purchases: write to support@kvinta.ai with enough to identify the purchase. Never send card details.
A refunded purchase’s remaining credit is removed.
Used credit. Credits are consumed as you use them. Used credits are not refundable where the law allows. In practice we treat a purchase as non-refundable once US$5 or more of its value has been used; below that, the unused part may be refunded. We measure this separately for each subscription period and each top-up, at the price you paid, not at our cost: the share of that purchase’s allowance you used (never more than all of it), times its price. Using less than that does not guarantee a refund. We tell RevenueCat our refund preference for each purchase on this basis, with a short note; for App Store purchases RevenueCat may pass it to Apple, and Apple still decides.
If a refund or chargeback is granted after that threshold was reached, the account can no longer buy top-ups; a new subscription is still allowed. Refunding a subscription ends that period’s allowance and keeps unrefunded top-up usage. Refunding a top-up removes its usage from your top-up balance.
Starting at once. Before a web checkout you must tick:
I want Kvinta to start immediately and understand I lose my right of withdrawal for credit I use.
We record that agreement, its wording version and the time before we hand you the checkout link. It asks us to start your service at once and acknowledges that you lose the right of withdrawal for the credit you use. Neither this acknowledgement nor the used-credit policy overrides your mandatory consumer rights, a store’s refund decision, or your remedies when the service is faulty or not as described.
Your content
You keep your rights in what you type, attach and dictate. You must have the right to upload and use it, including personal information, images, documents and other people’s material. You give us only the non-exclusive licence we need to host, copy, process and transmit it, through the service providers named in the Privacy Policy, to fulfil your requests and run Kvinta. That licence does not let us advertise with your content or sell it.
As between you and us, any rights we have in what Kvinta produces for you are yours, as far as the law allows. That does not mean the output is protected by copyright or free of other people’s rights: check before you publish or use it.
Acceptable use
Do not use Kvinta to make or spread unlawful content, infringe copyright or other rights, invade someone’s privacy, impersonate people to deceive, commit fraud, or harass or harm anyone. Do not upload material you have no right to process.
Do not get around access or usage limits, attack or overload the service, try to reach other users’ data, extract our system prompts or models, or resell access to your account. Do not reverse-engineer the app or the service, except where the law expressly allows it.
Reporting content
Report an answer, document, image or audio with Report in its More actions menu, or write to us. We review every report and may open the reported item to investigate, restrict unlawful or abusive use and answer you. A report does not automatically remove content or entitle you to a refund.
Suspension and termination
We may refuse a request, or suspend or close an account, for a material breach of these terms, unlawful use, fraud, or a threat to the service or other users. Where we reasonably can, we tell you why and give you a chance to put it right; an urgent security or legal problem may need immediate action. Write to us to ask for a review.
You may stop using Kvinta, cancel renewal and delete your account at any time. Ending the agreement does not take away your mandatory refund or consumer rights.
Availability and changes
We may change features and pause the service for maintenance; we do not promise uninterrupted availability. If we stop or materially reduce a paid service, we give reasonable notice where we can and any remedy the law requires.
We post changes to these terms here with a new date and tell you in the app about material ones. Changes never take away rights from a purchase already made. Price and renewal changes follow the notice and consent rules of the law and of the store or checkout you bought through.
Liability
As far as the law allows, Kvinta is provided “as is”. Subject to your mandatory consumer rights, we are not liable for indirect or consequential loss, and our total liability is limited to what you paid for Kvinta in the twelve months before the claim. Nothing here excludes or limits liability that the law does not allow to be excluded or limited, such as liability for fraud, or for death or personal injury caused by negligence.
Governing law
These terms are governed by the laws of the Commonwealth of Virginia, USA, without regard to its conflict-of-law rules. If you are a consumer, you keep the protection of the mandatory laws of the country where you live, and you may bring a claim there where those laws allow.
Please write to support@kvinta.ai first: most problems are solved that way. Subject to your mandatory consumer rights, any dispute that goes to court is decided by the state courts in Charlottesville, Virginia, or the United States District Court for the Western District of Virginia.
