Terms of service

The rules for using Kostuma, in plain words. By using the site, you agree to them.

Last updated October 4, 2026

These terms

Kostuma is a website, at kostuma.vercel.app, where horror fans find Halloween costumes, keep them in My Pumpkin Basket and try them on in the Fitting Room. These terms are an agreement between you and Kostuma (“we”, “us”) about using it.

By using Kostuma, you agree to these terms and to our Privacy policy, which says what we keep about you and why. When you create an account, you agree to both by ticking the box. If you don’t agree, please don’t use Kostuma.

These terms come in English, Spanish and Chinese. If the versions ever differ, the English one applies.

Who we are

Kostuma is made and run by its developers, a small independent team (not a registered company). You can reach us through the feedback form, or at vlad.atwok@gmail.com.

Kostuma is not affiliated with Perfect Corp. (YouCam), which provides its AI image service.

Who can use Kostuma

Kostuma shows horror imagery and is not intended for children. You must be at least 17 years old to create an account or use the Fitting Room.

Your account is yours alone. Give your real name and an email address you use, keep your password to yourself, and tell us at once if you think someone else is using your account. You’re responsible for what happens under it.

What Kostuma offers

Anyone can browse the costumes and keep the ones they like in My Pumpkin Basket, without an account. With an account, your basket follows you from device to device, and you can use the Fitting Room.

Kostuma doesn’t sell costumes or makeup: the links to buy them lead to other shops (see “Shops and other sites”).

Kostuma is free to use. We don’t take payments, and nothing on the site can charge you. Every account can try on one costume in the Fitting Room free of charge. For more, “Get Kostuma Pro” puts your account on a waitlist, and we’ll write to you about Kostuma Pro at the email you give us. Joining costs nothing and commits you to nothing.

We keep improving Kostuma, so features can change, pause or stop. We’ll try to keep what you’ve saved, such as your basket and your try-ons.

The Fitting Room

The Fitting Room puts a costume on your photos, then shows its makeup on your own face, step by step. You give it a photo of your face and, for most costumes, one of you from head to toe. The pictures are made by artificial intelligence: YouCam, a service of Perfect Corp.

  • Only photos of you. Upload photos of yourself and of no one else. Never upload photos of children, or photos with nudity.
  • One costume free. Every account can try on one costume free. Once its try-on is done, trying on another costume, or the same one with other photos, needs Kostuma Pro; deleting your photos doesn’t give it back. A try-on that fails can be tried again with other photos, within limits that stop abuse.
  • The pictures are previews. They show roughly how a costume and its makeup could look on you. Real clothes and real makeup will look different, and the AI can get things wrong.
  • Makeup is on you. The makeup guides are ideas, not professional or medical advice. Before you put on any product, read its label, test it on a small patch of skin, keep it away from your eyes unless it’s made for them, and stop if your skin reacts. You choose and use the products at your own risk.

Your photos, your pictures, your messages

Your photos and the pictures made from them stay yours. You allow us to store them, for up to 12 months or until you delete them, to send them to YouCam to make your pictures, and to show them to you, only to run the Fitting Room for you. They are shown only to you, signed in to your account. We don’t publish them, sell them, or use them to train AI. You can save your pictures to your device and share them yourself: we never share them for you.

If you send us feedback or an idea, we may use it to improve Kostuma, without owing you anything for it.

Shops and other sites

The Buy buttons and the shopping links in the makeup guides open other websites, such as Amazon. Those shops are not Kostuma: what you buy there, its price, delivery and returns are between you and the shop, under its own terms. We don’t check their products and aren’t responsible for them.

Kostuma earns nothing from these links today. If a link ever earns us a commission, it will be marked as one.

Characters, films and our work

Character names and film titles belong to their owners. Kostuma is not affiliated with, or endorsed by, any studio or retailer, and uses those names only to describe the costumes.

The rest of Kostuma is ours: its design, its writing, the costume photos and notes, and the makeup guides. Use them for your own Halloween; don’t copy or republish them.

Using Kostuma fairly

Please don’t:

  • break the law, or anyone’s rights, through Kostuma;
  • upload someone else’s photo, or pretend to be someone else;
  • copy the site in bulk, scrape it, or use bots or other automated tools on it;
  • get around the robot check, the limits on messages or try-ons, or any other protection, or try to get into accounts or systems that aren’t yours;
  • send messages that harass, threaten or spam.

Closing your account

You can stop using Kostuma whenever you like. To delete your account and everything kept with it, use “Delete my account” on your account page, or email vlad.atwok@gmail.com from the address on your account and we’ll do it within 30 days.

We may suspend or close an account that breaks these terms, or to protect Kostuma and the people who use it. Where we can, we’ll tell you why.

No guarantees

We work to keep Kostuma running and its facts right, but we provide it “as is” and “as available”, without warranties of any kind, as far as the law allows. The site can be unavailable, a try-on can fail or look wrong, and the notes about films and characters can contain mistakes.

Limits on our liability

As far as the law allows, Kostuma isn’t liable for indirect, incidental or consequential losses, such as lost data or lost profits, or for anything you buy from another shop. Our total liability for any claim about Kostuma is limited to what you paid us in the 12 months before it.

Nothing in these terms takes away the rights the law gives you as a consumer where you live.

Changes to these terms

When these terms change, the date at the top changes too. If a change matters to you, we’ll say so on Kostuma before it applies. Using Kostuma after that means you accept the new terms.
