This Agreement constitutes a legally binding contract entered into by and between you, whether personally or on behalf of an entity ("Licensee", "User", or "you"), and VIGAM Labs, an Indian business entity having its principal office in Bengaluru, Karnataka, India ("VIGAM Labs", "Company", "we", "us", or "our"), governing your access to and use of KLANG and all associated documentation, executables, updates, and website properties.

By checking any acceptance box, downloading, installing, copying, activating, or otherwise utilizing the Software, you acknowledge that you have read, understood, and unconditionally agree to be bound by the terms and conditions set forth herein.

2. Commercial Structure and Merchant of Record

2.1 Authorized Reseller and Merchant of Record

You acknowledge and agree that all commercial order processing, payment collection, invoicing, currency conversion, and sales tax/VAT remittance for paid digital licenses of the Software (including KLANG Pro) are conducted directly by our authorized reseller and Merchant of Record, Dodo Payments Inc. ("Dodo Payments"), a Delaware corporation located at 228 Park Ave S, PMB 54407, New York, NY 10003, United States.

2.2 Dual Contractual Relationships

When placing an order for the Software:

  2. Software License & IP: Your license to install, execute, and utilize the Software is granted directly by VIGAM Labs under the terms and limitations of this Agreement.

3. License Grants, Tiers, and Device Restrictions

3.1 License Tiers

Subject to the terms and conditions of this Agreement, VIGAM Labs grants you a personal, non-exclusive, non-transferable, non-sublicensable, revocable license to install and execute the Software under one of the following applicable tiers:

  • KLANG Free Tier (Evaluation License): Provides a limited, royalty-free evaluation license to install and use the basic features of the Software to index, catalog, and query up to a maximum threshold of two thousand five hundred (2,500) local audio files. This tier is provided for evaluation, personal, and educational purposes.
  • KLANG Pro Tier (Perpetual Commercial License): Upon payment in full of the one-time license fee through our Merchant of Record, VIGAM Labs grants you a perpetual, commercial, royalty-free license to index unlimited local audio files, search and organize synthesizer sound patches (including Vital presets), and utilize the Software for commercial and non-commercial music and sound design production.

3.2 Single-Device (1 Machine) Activation Limit

A single KLANG Pro license key authorizes activation and execution on exactly one (1) unique physical computer or operating system environment at any given time.

  • You may not activate, run, or share a single license key across multiple computers simultaneously.
  • If you upgrade, replace, or transfer your hardware, you must deactivate or remove the license from your previous device prior to activating the license on the replacement machine.
  • Any unauthorized multi-workstation deployment, concurrent network execution, or automated sharing of license keys constitutes a material breach of this Agreement and will result in the immediate revocation of the associated license key without refund.

4. Intellectual Property and Absolute Content Ownership

4.1 Ownership of the Software

The Software, including its source code, compiled machine binaries, object code, algorithmic structures, digital signal processing (DSP) logic, user interfaces, branding, icons, and visual assets, is the sole and exclusive intellectual property of VIGAM Labs. The Software is licensed, not sold.

4.2 Absolute User Content Ownership Guarantee

YOU RETAIN SOLE, ABSOLUTE, AND EXCLUSIVE INTELLECTUAL PROPERTY OWNERSHIP OF ALL AUDIO SAMPLES, RECORDINGS, SOUND EFFECTS, STEMS, SYNTHESIZER PRESETS, MUSICAL COMPOSITIONS, AND METADATA INDEXED, PROCESSED, AUDITIONED, OR EXPORTED THROUGH THE SOFTWARE.

VIGAM Labs asserts zero ownership, copyright, royalty, licensing rights, or claims over your creative musical works or sample libraries. The Software operates strictly as a local productivity tool for your existing audio files.

  • Zero Software Telemetry: The desktop Software does not incorporate background analytics SDKs, session recording trackers, user behavioral monitoring, or automated error/crash reporting modules.
  • Offline Execution: Following initial license key verification, the Software operates fully disconnected from the internet.

STRICT NO-REFUND POLICY: ALL SALES OF KLANG PRO DIGITAL SOFTWARE LICENSES ARE FINAL AND STRICTLY NON-REFUNDABLE. BECAUSE VIGAM LABS PROVIDES AN UNRESTRICTED KLANG FREE EVALUATION VERSION THAT ALLOWS USERS TO TEST PERFORMANCE, COMPATIBILITY, AND SEARCH ACCURACY ON THEIR SPECIFIC HARDWARE PRIOR TO PURCHASE, NO DISCRETIONARY REFUNDS ARE GRANTED ONCE A DIGITAL LICENSE KEY HAS BEEN GENERATED.

1. General Principle and Strict No-Refund Policy

VIGAM Labs provides specialized digital audio software engineered for music production, digital signal processing (DSP), and offline sample organization.

ALL PURCHASES OF KLANG PRO DIGITAL SOFTWARE LICENSES ARE STRICTLY FINAL, BINDING, AND NON-REFUNDABLE.

Because VIGAM Labs provides an unrestricted KLANG Free evaluation version that allows any prospective customer to download, install, test, and evaluate the Software—including its local indexing speed, DAW drag-and-drop compatibility, audio search accuracy, and system resource footprint—free of charge prior to purchasing a Pro license, our sales are conducted on a firm, non-returnable basis.

By placing an order for a KLANG Pro license via our Merchant of Record (Dodo Payments Inc.), you expressly acknowledge and agree that:

  1. You have had adequate opportunity to evaluate the Free version of KLANG on your designated computer hardware;
  2. Digital software licenses are digital goods that are delivered immediately upon checkout;
  3. You waive any discretionary right of withdrawal or return once the digital license key has been generated and dispatched.

2. Non-Waivable Statutory Rights Exception

Nothing in this Policy is intended to limit, exclude, or disclaim any statutory consumer rights that cannot be lawfully waived or modified under the mandatory consumer protection laws of your jurisdiction.

For consumers in jurisdictions with statutory right-of-withdrawal mandates (e.g. EU/UK), rights are waived upon immediate delivery with prior express consent. For verified statutory defect conformity claims, VIGAM Labs provides technical remedies as detailed below.

3. Electronic Delivery and Technical Defect Remedies

3.1 Digital Fulfillment Guarantee

KLANG Pro license keys and installer links are electronically delivered to the email address entered during checkout immediately upon checkout completion (typically under 60 seconds).

If you have completed checkout but have not received your license key within two (2) hours, please check your spam filters and contact klang.help@outlook.com with your order ID.

3.2 Technical License Activation Remedies

If an electronically delivered license key is cryptographically corrupted, invalid, or fails to activate the Software on an eligible computer environment meeting our published minimum system requirements (Windows 10/11 64-bit or macOS 14+ Apple Silicon):

  • You must report the issue to klang.help@outlook.com within fourteen (14) calendar days of purchase;
  • Our engineering team will investigate and provide an active replacement key or technical fix within our standard support response SLA of 2 to 4 business days;
  • If VIGAM Labs determines that a verified technical failure on our licensing server prevents activation and cannot be resolved within seven (7) business days, VIGAM Labs will authorize our Merchant of Record to issue a full refund.

4. Subscription Cancellation (Not Applicable)

KLANG Pro is sold strictly as a one-time perpetual digital license. There are no recurring subscriptions, automatic monthly/annual renewals, or unexpected recurring fees.

5. Dispute Resolution and Chargeback Protection

We strongly urge customers to contact us directly at klang.help@outlook.com prior to initiating any payment dispute or chargeback with their bank or credit card provider.
