Terms of Service

1. Purpose

These terms set the conditions for using Signature Studio (the "Service"), the website run by Apertix (the "Operator"), and the rights and duties of the Operator and members.

2. Definitions

• Service: a website where AI draws signature images from the English or Hangul name (including initials and emblem) and styles a member enters, and provides the chosen signature as PNG files and an A4 practice sheet PDF. The practice sheet is written in Korean.
• Member: a person who joined by invitation and accepted these terms.
• Try: one request that draws signature options. A try you buy draws 4 options from the 4 styles in the cart. A free try draws 1 option in one style, except where section 9 says it draws 4.
• Free try: a try the Operator gives at no charge.

4. Who and where

The Service in English is offered to people in the United States, including California. It is not offered in the European Economic Area or the United Kingdom.

You must be 14 or older to use the Service. If you are under 18, please read these terms with a parent or guardian and get their permission first. We ask for your birth month and year when you sign up and keep only your age group. If we learn that someone under 14 has an account, we close it and delete its data.

5. Posting and changing these terms

The Operator posts these terms in the Service. If the terms change, the changes and their effective date are announced in the Service 7 days before they take effect (30 days if the change is unfavorable to members). If a change reduces your rights, we ask you to accept it before it applies to you. If you don't agree, you can stop using the Service and delete your account, and you can still download your signatures first.

6. Notices

The Operator sends notices to your registered email or posts them in the Service.

7. Joining

The Service is currently invite-only. The contract is formed when an invited person accepts these terms and the handling of personal information and finishes signing up. We may refuse or end a membership that uses someone else's email or was previously restricted.

8. Your account

• Each person uses one account, and accounts can't be transferred or lent.
• You are responsible for your password. After several wrong passwords in a row, login is locked for protection and a reset link is sent to your registered email.
• Logging out or changing your password on one device logs you out on all devices.

9. Free tries

You receive free tries when you join, while free spots last. A free try draws 1 option in the one style you pick. If you joined the waitlist by November 13, 2026, 10 PM Eastern Time, the free tries you receive when you join draw 4 options from 4 styles, like a try you buy; so does a free try we gave you with a notice that it draws 4.

"Draw again" counts as one try, and so does "4 more" of a style you like; each draws as many options as the try it uses (4 or 1). Viewing results you already made doesn't count.

Free tries expire (10 days after you receive them, or the date we told you), can't be exchanged for cash and aren't refundable. The ones closest to expiry are used first. Signatures you already made can still be downloaded after you use up your free tries.

While the referral program runs, members get an invite link. A friend who joins with it gets extra free tries, and the inviter gets free tries once the friend's try produces at least one option (once per friend, with a limit per 30 days). Free tries gained by inviting yourself or by other improper means may be taken back.

10. Buying tries, payment and restoring tries

From November 17, 2026 you can buy packs of tries (see Pricing). Each pack is a one-time purchase in US dollars; nothing renews. Prices are shown before you pay, and any sales tax is added at checkout.

Our order process is conducted by our online reseller, which is the Merchant of Record for all our orders: you buy from the reseller, and it handles payment, receipts, sales tax and returns. Its name and buyer terms are shown at checkout and on your receipt, and its buyer terms also apply. We don't receive or store your card details.

Tries you buy are valid for 365 days and are used after your free tries. They can't be exchanged for cash or moved to another account. Refunds follow the Refund Policy.

If you are under 18, you may buy only with a parent or guardian's permission, up to $7.99 at a time and 3 times a day, or you can ask a parent or guardian to pay with a link we email them. A parent or guardian can ask us for a refund of a purchase made without their permission.

If a drawing error produces no options at all, the try used (free or bought) is restored. A drawing error means the AI service gave no image (refusal, timeout or outage) or only clearly unusable images such as blank images or images cut off at the edge. If at least one option appears, nothing is restored, even if you didn't pick it, don't like it, or the spelling or look differs from what you expected. Nothing is restored if you cancel after drawing starts. Restores of free tries are limited to 3 per member in the last 7 days, and a bought pack's tries can be restored twice per pack (if more of them fail, email us and we'll refund them), and an expired free try is restored as one that lasts for one day.

11. What the Service provides

The Operator provides signature drawing, comparing and choosing options, PNG files, an A4 practice sheet PDF and storage of your signatures. The practice sheet PDF is made on your device and isn't uploaded to our servers. The Service may pause for maintenance or outages; we announce it in the Service when we can.

12. AI results and disclaimer

We don't claim ownership of the signatures you make, and you may use them as your own signature. AI output may not be protected by copyright and may resemble someone else's result. The Service is provided as is, without warranties to the extent the law allows.

Results are made by AI, so spelling mistakes and unexpected shapes can occur. We don't guarantee a result can be registered as a trademark. The Service uses generative AI to draw images. Every option and signature page is marked as made with generative AI, and downloaded PNG files carry the same information.

This service creates signature images. It does not verify a signer's identity, a signature's authenticity or a document's integrity, and it does not guarantee legal effect.

13. Your duties and limits

• Enter only your own name.
• Don't use the Service to forge anyone's signature or documents. Violations lead to account suspension.
• Don't imitate the signature of a real celebrity or call the Service excessively by automated means.
• Tell us about inappropriate or wrong results with "Tell us" in the Service. The Operator will review and act.

The Operator may limit the number of tries and the request rate to prevent abuse.

14. Storage and deletion

Records and images are kept for 1 year after your last visit and then deleted. Accounts, the database and images are stored in Seoul, South Korea. You can delete records, signatures and your account yourself at any time. See the Privacy Policy and Data Trust Principles.

15. Transfer to an AI provider

To draw signatures, what you enter is sent to OpenAI in the United States. If you ask for Hangul spellings of your name, the name you enter for it is sent to Anthropic in the United States. See Who gets your data.

16. Changing or ending the Service

Changes to the Service are announced in the Service. If the Service ends, we notify you by email and in the Service 30 days ahead and let you download your signatures during that time. After it ends, member records and images are deleted.

17. Leaving

You can delete your account at any time in "My signatures", or by email (help@apertix.ai) if you can't log in. Deleting removes records, signatures and the account; only information the law requires us to keep is kept for that period. How to delete your account

18. Limits of responsibility

The Operator isn't responsible when it can't provide the Service for reasons it can't prevent, such as natural disasters, network failures or outages of an outside AI service. You are responsible for where and how you use your signatures. To the extent the law allows, our total liability to you is limited to the greater of the amount you paid us in the last 12 months or US$50, and we aren't liable for indirect or consequential damages. Nothing in these terms limits a right or liability that the law of the place where you live doesn't allow us to limit.

19. Disputes and individual arbitration

Please contact us first (help@apertix.ai) and give us 60 days to try to resolve a dispute in good faith.

If you live in the United States, you and the Operator agree to resolve disputes by binding individual arbitration, not in court, and neither of you can bring a claim as part of a class or representative action. Arbitration is run by the American Arbitration Association under its Consumer Arbitration Rules, online or in the county where you live. We pay the fees the rules assign to the business. Either of you can instead use small claims court for an individual claim that qualifies. This section doesn't stop you from seeking public injunctive relief where the law gives you that right, and if a part of it can't be enforced, that part goes to court.

You can opt out of arbitration within 30 days after you first accept these terms by emailing help@apertix.ai with the subject "Arbitration opt out". Opting out doesn't change anything else.

These terms follow the laws of the Republic of Korea, but you keep the mandatory consumer protections of the state where you live, including California. Claims not covered by arbitration go to the competent courts of the Republic of Korea, or the courts where you live if the law gives you that right.

California residents: under California Civil Code section 1789.3, the Service is provided by Apertix, 401-GA25, 454 Gangseo-ro, Gangseo-gu, Seoul, 07582, Republic of Korea, +82-10-5947-2037. There is no charge for the Service in English. For complaints, you can contact us at help@apertix.ai, or the Complaint Assistance Unit of the Division of Consumer Services, California Department of Consumer Affairs, 1625 North Market Blvd., Suite N 112, Sacramento, CA 95834, (916) 445-1254 or (800) 952-5210.
