Contour

Terms of Service

Last updated: 2026-11-11 · Liu Guangkai · https://contour.niamori.ai

These Terms of Service ("Terms") govern your use of Contour at https://contour.niamori.ai (the "Service"), operated by Liu Guangkai ("we", "us", "our"). By using the Service, creating an account, or subscribing, you confirm that you have read and agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Service.

1. Service Description

Contour is an online tool that converts raster images (such as PNG, JPG and WebP) into vector graphics (SVG, and on Pro also PDF, EPS and DXF). The conversion runs inside your web browser: your images are opened, traced and exported on your own device and are not uploaded to our servers.

The Service is a digital software-as-a-service product delivered over the internet. Paid features are available immediately after a confirmed payment. Vector results are an automatic interpretation of your image and may differ from it; review them before use.

2. Accounts and Eligibility

You can use the Free plan without an account. To subscribe to Pro you must create an account with a valid email address, verify it, and keep your login credentials confidential. You are responsible for all activity under your account. Tell us immediately at support@niamori.ai if you suspect unauthorized use.

You must be at least 18 years old, or the age of majority where you live, to create an account or subscribe. If you use the Service on behalf of an organization, you confirm that you are authorized to accept these Terms for it.

3. Plans

We offer a Free plan and a Pro subscription billed monthly. The current limits, features, and price of each plan are listed at https://contour.niamori.ai/pricing. We may change plan features or introduce new plans; a change never reduces what you have already paid for during the current billing period.

4. Billing and Payment

Our order process is conducted by our online reseller Waffo Pancake (Waffo.com Limited), which is the Merchant of Record for all orders. Waffo Pancake processes your payment, calculates and collects applicable taxes, and issues your receipts. Its own terms also apply to your purchase. Payment card data is handled by Waffo Pancake and is never stored on our servers.

Pro costs US$5 per month, plus applicable taxes such as VAT, GST, or sales tax, which are shown at checkout. By subscribing, you authorize Waffo Pancake to charge your payment method US$5 plus applicable taxes at the start of each monthly billing period. Your subscription renews automatically every month until you cancel it as described in Section 5. Waffo Pancake emails you before each renewal charge.

5. Cancellation

You can cancel your subscription at any time:

  • Online, from your account page (Cancel renewal).
  • By email: send a cancellation request from your account email to support@niamori.ai.

Cancellation stops future renewals. Pro stays active until the end of the billing period you have already paid for, and you will not be charged again.

6. Refund Policy

You can get a full refund of a Pro payment, whether it is your first payment or a renewal, if you request it within 14 days of that payment from your account page or by emailing support@niamori.ai from your account email. When the refund succeeds, the Pro access paid for by that payment ends. A refund does not cancel future renewals; cancel the subscription as well if you do not want to be charged again.

After 14 days, payments are non-refundable because the Service is delivered immediately, except that we always refund duplicate or erroneous charges, and we provide a pro-rated refund if we end your subscription for reasons other than your breach of these Terms. Any refund or withdrawal right you have under the mandatory law of your country is preserved.

Refunds are issued by Waffo Pancake to the original payment method. Depending on your bank, it can take 5–10 business days for a refund to appear.

7. Billing Questions and Disputes

If you believe a charge is wrong, please contact us at support@niamori.ai before disputing it with your bank. We reply within 2 business days and correct confirmed billing errors within 5 business days.

8. Your Images and Results

You keep all rights to the images you convert and to the vector results. Because conversion happens in your browser, we do not receive, store, or look at your images. You confirm that you have the right to convert and use every image you process, including any logos, artwork, or trademarks it contains.

9. Acceptable Use

You agree not to use the Service to:

  • process content that is illegal, sexualizes minors, infringes intellectual property or privacy rights, or is used for harassment, fraud, counterfeiting, or deception;
  • circumvent plan limits or access controls, or share a Pro account with others;
  • overload the Service, scrape it, or access it by automated means other than its normal interface;
  • resell or sublicense access to the Service without our written approval;
  • violate any applicable law, regulation, or card network rule.

10. Privacy and Data

Our Privacy Policy explains what personal data we collect and how we use it. You can delete your account from your account page at any time after cancelling an active subscription; payment records are kept as long as accounting and tax law require.

11. Disclaimers and Limitation of Liability

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. We do not guarantee that results will match your image exactly, be suitable for a particular machine or printer, or that the Service will be uninterrupted. Always review results before cutting, engraving, or printing.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE ARE NOT LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOSS OF DATA, MATERIALS, OR PROFITS. OUR TOTAL LIABILITY FOR ANY CLAIM IS LIMITED TO THE AMOUNT YOU PAID US IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM. Nothing in these Terms limits liability that cannot be limited by law.

12. Suspension and Termination

We may suspend or close your account if you materially breach these Terms, if we reasonably suspect fraud or abuse, or if the law requires it. If we close your account for any other reason, we refund the unused part of your prepaid subscription. You may stop using the Service at any time.

13. Discontinuing the Service

We may stop offering Pro or the Service. We will email subscribers at least 30 days in advance and stop all future renewals. Pro stays available until the end of the period you have already paid for; if we shut the Service down before that date, we refund the unused part of that period.

14. Governing Law and Disputes

These Terms are governed by the laws of the country where the operator of the Service resides, without regard to its conflict-of-law rules. Mandatory consumer protection laws of your country of residence still apply to you. Before starting any formal proceedings, please contact us at support@niamori.ai so we can try to resolve the issue informally.

15. Changes to These Terms

We may update these Terms. We will email subscribers, or show a notice in the Service, at least 14 days before a material change takes effect. Continuing to use the Service after the effective date means you accept the updated Terms. If any provision is unenforceable, the rest remains in effect.
