Version 2026-09, in effect from 5 September 2026. Written by Anti in plain language, and not reviewed by a lawyer. That is said here rather than hidden so you can weigh it. Every clause means what it plainly says; if one is unclear, ask, and the answer will be given plainly rather than resolved against you.
The version matters: every purchase records which version it was made under, and that version governs that license (see "Agreement, and which version applies").
"Anti" and "Anti Tapes" mean Adi Dizdarevic, trading as Anti Tapes, in Bellevue, Washington, United States. "You" means the person using Anti Studio, or the company on whose behalf they use it; if you agree for a company, you confirm you may bind it. "The studio" means Anti Studio, the application at anti.fyi/studio. "An export" means what the studio hands out: a theme JSON, an engine snippet, or a rendered sound pack.
The Anti engine is open source under the MIT license. Use it, modify it, ship it, sell what you build with it. Nothing on this page applies to it.
The theme format is open and documented, and the schema is published as machine-readable data. A theme you write yourself, in a text editor or with your own tools, is entirely your own and outside these terms. If you never open Anti Studio, you owe Anti nothing, ever.
Anti Studio itself is free to play. Every control, every preview, every sound, no account and no payment. You can design a complete sound identity and hear it across an entire interface without buying anything.
Anti Studio is proprietary software owned by Anti Tapes. It is free to use, including its full export, for personal work. What a commercial license buys is the use of that same studio when what you make in it ships somewhere that earns money.
That is a license to use this application for a given purpose. It is not a claim over sound, over your design, or over the engine.
You designed it. Anti claims no ownership of your theme, your parameter choices, or the identity they make. These terms govern the use of the studio, not the authorship of what you made in it.
The full studio and the full export, at no cost and with no license required, for personal projects, portfolios, education, learning and experimentation. Nothing is degraded, watermarked or held back, and there is no key to enter.
A studio license for one brand: a company or product line, and the people working on that brand's products. Use a studio-made identity in one commercial product or product family under that brand, across web, mobile, desktop and games. Unlimited end users, no royalties. One license per brand; a distinct brand, or an agency's distinct client, needs its own. The price is one payment, in US dollars, with sales tax or VAT added at checkout where Anti is required to collect it.
Commercial means the product earns money, or you are being paid to build it. If a case is genuinely unclear, ask, and the answer will be given plainly rather than resolved against you.
Original identity work, tuning by ear, implementation help, and registration: an entry in the public register recording your exact theme, by fingerprint, and its signature seed, dated, with a commitment from Anti not to issue that configuration to anyone else. Bespoke work is quoted, and the quote carries its own terms; these terms cover the studio license that comes with it.
What that registration promise is, exactly. It covers the specific registered configuration and seed. It does not reserve the surrounding territory, and no honest register could: the parameters are continuous, so a value moved slightly is a different theme, and claiming a region of that space would be claiming to own a key signature or a material. Two brands can end up in adjacent territory the way two brands can both use a grotesque. Registration is a promise by Anti, not a restriction on you.
A commercial license does not expire. Retuning your theme and re-exporting it is free for as long as you hold the license. A sound identity is a long-lived asset and its license should not need renewing.
Two things, and they are the only restrictions on this page.
Do not redistribute exports as assets for others to reuse. The sounds ship inside your own products, where they play as that product's interface. What you may not do is supply them to other people as sounds: a sample pack or sound library, a UI kit, template, theme or starter with the audio bundled in, a marketplace listing, a dataset, or any product whose purpose is to hand the sounds on. A theme JSON is your work and you may share it as you like; the restriction is on the rendered audio and the packs. Sharing a pack with your own team, your agency, or a contractor working on your product is use, not redistribution.
Do not copy, host or resell the studio. The studio is proprietary. Do not mirror it, embed it in another product, offer it as a service, or remove or bypass its license gate. (The engine is MIT and none of this applies to it.)
If you break either of these in a way that matters, Anti may end your studio license by writing to the purchase address, and no refund is owed for a license ended that way. Honest mistakes get a mail first, not a termination.
You agree to these terms by pressing Get commercial, or Unlock with a key, in the studio's export gate, where a line at the foot of the dialog says so. Nothing else asks you to agree to anything, and using the free studio without buying commits you to nothing beyond the two restrictions above.
When you buy, the studio records which version you were shown and passes it to the purchase, so Anti holds its own record of what you agreed to. The version recorded on a purchase governs that license, for as long as you hold it. A later revision applies to your use of the studio from the day it is posted here, and it can never narrow a license you already bought: nothing you were granted is taken back by a new version. When you enter a key later, on another machine, pressing Unlock acknowledges the terms of use in force that day; your license itself stays under the version it was bought under.
Revisions are posted on this page with a new version and date. There is no other notice, and none is needed, because a revision cannot reach back into a purchase.
Your key is a signed statement that a purchase happened. It verifies offline, in your own browser, and Anti keeps no account for you: the only record is a purchase row holding the email, the checkout session, the tier, the brand, which terms version the purchase was made under, and the date. Lose the key and it is sent again, unchanged, to the address that bought it.
A key cannot be revoked, technically, and that is a design choice: it is a receipt, not a leash. What keeps a license honest is this agreement, not the key. The key is for the brand it names; do not publish it or hand it beyond that brand's team.
Fourteen days, in full, on request, no reason needed. Write to hello@anti.fyi from the purchase address within fourteen days of buying a commercial license and it is refunded to the card that paid. A refunded license ends: the purchase is marked, the key stops being sent again, and although the key you already hold will still verify (see above), using it after a refund is a breach of these terms.
After fourteen days there are no refunds, because the whole studio is free to audition, in full, before anything is bought. If something is genuinely broken for you after that, write anyway; it gets sorted.
Payments are taken by Stripe. Anti never sees your card details. Prices are in US dollars; Stripe shows the total, including any tax, before you pay. The checkout and your card statement show the name AD&: that is the design practice Anti Tapes is made by, and the same seller. Bespoke work is invoiced as quoted.
The studio and its exports are provided as they are. Anti does not promise that the studio will be uninterrupted or free of errors, that any sound will suit a particular purpose, or that a rendered pack matches what a given browser plays live, because browsers differ. Anti will fix what is broken as it can, and that is the whole of the warranty.
To the extent the law allows, Anti's total liability to you under these terms, for any reason, is the amount you paid for the license in question, and Anti is not liable for indirect or consequential loss: lost profit, lost data, or the cost of replacing a sound identity. Nothing here excludes liability that cannot be excluded by law, and nothing here limits any right you have as a consumer that cannot be limited by agreement.
These terms are governed by the laws of the State of Washington, United States, without regard to its conflict of law rules. Any dispute that cannot be settled by writing to each other is brought in the state or federal courts sitting in King County, Washington, and both of us agree to that venue. Write first: almost everything is sorted by mail.
What Anti keeps, and how little it is, is on the privacy page. It is part of these terms.
