Terms of Service

Last updated 29 September 2026

Who we are

Sinua is made by Efe Barkın Köse, a sole proprietorship in Türkiye (Şehit Cengiz Karaca Mah. 1057 Cad. No: 25 Daire: 8, Çankaya, Ankara) ("we", "us"). These terms cover sinua.dev and Sinua Studio at studio.sinua.dev. By creating an account or starting a subscription you agree to them. Questions go to [email protected].

The Sinua runtime is open source

The engine and the Web, iOS, Android and React Native packages are published under the Apache License 2.0. You can use them in any project, commercial or not, without an account. Their use is governed by that license, not by these terms. The name "Sinua" and its logo are ours; the license doesn't grant rights to them.

Sinua Studio is a subscription

Studio is sold monthly or yearly. Prices are shown before you pay.
Every new customer starts with a 14-day free trial. A payment method is needed to start it; you aren't charged until the trial ends, and cancelling before then costs nothing.
After the trial, the subscription renews automatically at the start of each period until you cancel.
Payments are processed by Polar Software, Inc., our merchant of record. Polar sells the subscription to you, charges you, and handles invoices and sales tax. Polar's Checkout Buyer Terms apply to the purchase itself.

Cancelling and refunds

You can cancel any time from Manage subscription in the Studio's account menu. Access continues until the end of the period you've paid for. Refunds are described in our Refund Policy.

What you make is yours

The designs you create in Studio, the FX Spec files you save or download, and the code Studio exports for you belong to you. You can use them in personal and commercial projects, and you don't need a subscription to keep using what you've already exported. We don't claim any rights to your designs, and we use them only to store them for you.

Studio itself, its code, its interface and the presets it ships with remain ours. You may not copy or resell Studio or offer it as a service.

Your account

An account is for one person. Don't share your sign-in or your subscription.
Keep your email account secure: we sign you in with codes sent to it.
Don't try to get around the subscription or sign-in checks, overload or probe the service, scrape it, or use it for anything unlawful.

We may suspend an account that breaks these rules. If we do, we'll tell you why.

Changes

We improve Studio continuously, so features change. If we raise a price, we'll email you at least 30 days before it applies, and it takes effect from your next billing period. If we change these terms in a way that matters to you, we'll say so by email or in Studio before the change takes effect.

No warranty

Studio is provided "as is". We work to keep it available and correct, but we can't promise it will always be uninterrupted or free of errors.

Limitation of liability

To the extent the law allows, we aren't liable for indirect or consequential losses, lost profits or lost data, and our total liability to you is limited to what you paid us for Studio in the 12 months before the claim. Nothing here limits liability that can't be limited by law.
