End User License Agreement

Last updated: 2026-09-29 · Version v1.2

End User License Agreement (EULA)

This End User License Agreement (“EULA”) is a binding contract between you (an individual or, where applicable, the entity you represent) and Hangzhou Wanxiang Xunsheng Technology Co., Ltd. (杭州万像循声科技有限公司) (the “Company”, “we”, “us”), a company incorporated in Mainland China (Hangzhou, Zhejiang Province). By installing, copying, activating, or using SoundSeeker (the “Software”), you agree to be bound by this EULA. If you do not agree, do not install or use the Software.

Purchases are completed through Paddle.com Market Limited (“Paddle”), our authorized reseller and Merchant of Record. Paddle is the seller of record for your payment, but the Software is licensed to you by the Company under this EULA.

Please Pay Special Attention

The following clauses materially affect your rights:

  • Section 3 — License Scope and Single-User Rule
  • Section 5 — Fees, Purchases through Paddle (Merchant of Record), and Refunds
  • Section 6 — Anti-Circumvention
  • Section 9 — Term and Termination
  • Section 10 — Warranties and Limitation of Liability
  • Section 11 — Governing Law (PRC law) and Dispute Resolution (Hangzhou courts)
  • Section 12.5 — Updates to this EULA

1. Definitions

  • “Software” means the SoundSeeker application binaries, models, configuration files, documentation, and any updates we make available.
  • “License Key” means a unique credential we issue to authenticate your right to use the Software under a specific edition.
  • “Edition” means the version of the Software you have licensed. Edition is Personal (perpetual) or Tools (perpetual). Team and enterprise use are scoped under a separate written agreement.
  • “User” means the natural person identified as the licensee for a Personal or Tools license.

2. Grant of License

2.1 Subject to your compliance with this EULA and payment of applicable fees, the Company grants you a non-exclusive, non-transferable (except as expressly permitted), revocable license to install and use the Software for your own internal creative or professional use, in accordance with the Edition you have licensed.

2.2 This is a license, not a sale. All rights not expressly granted are reserved by the Company.

3. License Scope by Edition

3.1 Personal Edition (Perpetual)

  • For one (1) named natural person only.
  • May be activated on up to one (1) primary device at a time, with a limited number of device-change re-activations as documented in the product.
  • The Personal license is strictly single-user and may not be shared. Sharing the License Key, the activated installation, or the account with any other person is a material breach of this EULA.
  • Receives free Software updates within the same major version.

3.2 Tools Edition (Perpetual)

  • For one (1) named natural person.
  • May be activated on up to one (1) primary device.
  • Provides access to a defined set of utility tools as listed on our website at the time of purchase.
  • Receives free Software updates within the same major version.

3.3 Trial / Evaluation

  • We may offer time-limited evaluation access. When the evaluation period ends, the Software downgrades to a free tier with reduced functionality. Files and projects you created during the trial remain accessible to you.

4. Restrictions

Except to the extent expressly permitted by this EULA or by applicable mandatory law that cannot be waived, you shall not:

(a) copy the Software except as necessary to install and run it under your license; (b) sell, sublicense, rent, lease, lend, or otherwise transfer the Software, any License Key, or your account, except as expressly authorized in writing; (c) reverse-engineer, decompile, disassemble, or attempt to derive the source code, algorithms, or trained model weights of the Software; (d) circumvent, disable, or attempt to circumvent any license-enforcement, authentication, integrity, or security mechanism; (e) use the Software to develop a competing product or to extract its models for use in another product; (f) remove or alter any proprietary notices, trademarks, or attributions; (g) use the Software in any way that violates applicable law, infringes any third party’s rights, or interferes with our infrastructure.

We may rate-limit, suspend, or terminate access where we observe activity inconsistent with this Section. See Section 9.

5. Fees, Purchases through Paddle, Activation, and Refunds

5.1 Fees and Merchant of Record. Fees for the Edition you have purchased are as set out at the time of purchase. Your purchase is placed with and completed through Paddle.com Market Limited (“Paddle”), our authorized reseller and Merchant of Record, which is the seller of record for the payment: Paddle collects payment, calculates and remits any applicable taxes, issues your receipt/invoice, and processes refunds. The Software is licensed to you by the Company under this EULA. Your purchase is also subject to Paddle’s Buyer Terms (https://www.paddle.com/legal/checkout-buyer-terms).

5.2 Activation. The Software requires online activation. The information processed for activation is described in the Privacy Policy.

5.3 Refunds. The free trial (Section 3.3) lets you evaluate the Software before purchase. Purchases are non-refundable, except where a refund is required by mandatory law that applies to you or by Paddle’s Buyer Terms. Refunds, where due, are processed by Paddle as Merchant of Record. To request one, contact support@soundseeker.ai or Paddle with your order details. Nothing in this EULA limits mandatory consumer rights that cannot be excluded.

6. Anti-Circumvention

6.1 You shall not bypass, disable, modify, or attempt to interfere with any technical protection measure, integrity check, license-enforcement mechanism, or update mechanism of the Software.

6.2 You shall not knowingly use, distribute, or assist others in using or distributing any tool whose primary purpose is to circumvent the measures described in 6.1.

6.3 The Software may detect tampering or unauthorized modification and may, in such cases, refuse to operate or operate in a reduced-functionality mode.

7. Your Data and Content

7.1 Your Content stays yours. All audio assets, project files, and other content you import, create, or process with the Software (“Your Content”) remain your property or that of your licensors. The Company claims no rights in Your Content beyond the limited technical processing necessary to provide the Software to you.

7.2 You are responsible for the lawfulness of Your Content. You represent and warrant that you have the rights necessary to use, store, and process Your Content with the Software. The Company does not screen or vet Your Content.

7.3 Personal information. How we process personal information is described in the Privacy Policy.

8. Intellectual Property

8.1 The Software, including its code, AI models, user interface, documentation, and trademarks, is owned by the Company or its licensors and is protected by copyright, trademark, trade-secret, and other laws.

8.2 The Software incorporates open-source components. Their notices and licenses are supplied in the LICENSES folder with the Software; that folder also contains SOURCE-OFFER.txt with instructions for obtaining covered corresponding source and build materials. Rights granted by the applicable open-source licenses prevail over conflicting restrictions in this EULA. For a work that is combined or linked with an LGPL component, you may, to the extent the applicable LGPL version requires, modify that work for your own use and reverse-engineer it to debug those modifications. This does not grant rights beyond those required by the applicable open-source licenses, including rights to redistribute proprietary code, share accounts, access unpurchased features, or exceed your licensed device allowance.

FFmpeg source and build information for the corresponding versions are available at Open-source licenses & source.

8.3 Feedback you voluntarily provide may be used by the Company without restriction.

9. Term and Termination

9.1 This EULA is effective when you accept it and continues until terminated.

9.2 You may terminate by uninstalling the Software and ceasing all use.

9.3 The Company may terminate this EULA on notice if:

  • (a) you materially breach this EULA (including Sections 3, 4, 6) and, if curable, fail to cure within a reasonable period after notice;
  • (b) you fail to pay any fees due; or
  • (c) continued provision of the Software to you would expose us to legal risk.

9.4 Effect of termination. Upon termination, the license granted to you ends. You must cease use under the terminated license and remove copies no longer licensed to you. Sections 4, 7, 8, 10, and 11 survive termination.

10. Warranties and Limitation of Liability

10.1 Mandatory rights. Your mandatory rights concerning conformity, defects, updates and remedies remain in force.

10.2 Service condition. Subject to Section 10.1 and other express purchase terms, the Software is supplied as available without an additional contractual warranty period.

10.3 AI outputs. We make no warranty as to the accuracy, completeness, or suitability of any output of the Software’s AI features.

10.4 Limitation of liability. To the maximum extent permitted by applicable law, the Company’s aggregate liability for any claim arising out of or relating to the Software or this EULA is limited to the greater of:

  • (a) the amount you paid us for the relevant Edition in the twelve (12) months preceding the event giving rise to the claim; or
  • (b) USD 100.

10.5 Excluded damages. To the maximum extent permitted by applicable law, the Company shall not be liable for any indirect, incidental, consequential, special, exemplary, or punitive damages, or for lost profits, lost data, or business interruption.

10.6 Mandatory exceptions. Nothing in this Section excludes or limits liability for: (a) death or personal injury caused by our negligence; (b) fraud or fraudulent misrepresentation; (c) any other liability that cannot be excluded under applicable mandatory law; or (d) loss caused by our intent or gross negligence — nothing in this Section limits liability for property loss caused by our intentional acts or gross negligence, which cannot be excluded under Article 506 of the PRC Civil Code.

11.4 Payments and refunds. Disputes concerning the payment transaction, billing, taxes, or refunds are, in the first instance, between you and Paddle as Merchant of Record, governed by Paddle’s Buyer Terms.

11.5 Mandatory consumer rights. Where you are a consumer in a jurisdiction whose mandatory consumer-protection law gives you the right to bring proceedings in the courts of your habitual residence, this Section does not restrict that right.

12. General

12.1 Entire agreement. This EULA, together with the Terms of Service, Privacy Policy, and Cookie Policy, constitutes the entire agreement between you and the Company concerning the Software.

12.2 Severability. If any provision is held invalid or unenforceable, the remaining provisions remain in effect.

12.3 No waiver. Failure to enforce any right is not a waiver of that right.

12.4 Assignment. You may not assign this EULA without our prior written consent. We may assign in connection with a merger, acquisition, or sale of assets.
