End User License Agreement (EULA)

MONKEY MASTERING

Last updated: 10 August 2026

BETA NOTICE — v1.2 BETA. The Software is currently in private BETA. These terms will be revised and reissued at the commercial v1 launch. Feedback from BETA users will help shape the final terms. In case of conflict between this notice and the rest of the EULA, the specific clauses of the BETA License (§2.ter) prevail for the duration of the BETA.

IMPORTANT — READ CAREFULLY BEFORE INSTALLING OR USING THE SOFTWARE.

This document constitutes a binding legal agreement (the "Agreement" or "EULA") between you (the "User" or "Licensee") and Javier J. Redondo, Spanish Tax ID 78503120A, owner of the MONKEY MASTERING brand (the "Licensor"), governing the use of the MONKEY MASTERING software (the "Software"). The Licensor's address and remaining identification details are set out in the Legal Notice.

By installing, activating, or using the Software, the User agrees to be bound by the terms of this EULA. If you do not accept them, do not install or use the Software and request a refund pursuant to the Terms of Sale.

1. Definitions

• Software: the MONKEY MASTERING audio plugin, including its binaries (VST3, AU), data files, factory presets, documentation, and all updates.
• License: a non-exclusive, non-transferable, revocable, limited right to use the Software under the terms of this EULA.
• License key: the unique alphanumeric string delivered to the User after purchase (or issued as a BETA key during the private BETA), identifying their right of use.
• System: each individual device (computer) on which the Software is installed and activated.

2. Grant of license

The Licensor grants the User a personal, non-exclusive, non-transferable, revocable, and limited license to:

• Install and activate the Software on a maximum of two (2) Systems simultaneously for the User's personal use (e.g. a main studio and a laptop).
• Use the Software for personal or professional purposes (mastering the User's own audio or for clients), provided the mastering is performed by the User.
• Make reasonable backup copies of the Software installer, exclusively for the User's own use.

2.bis Trial / Evaluation license

The Licensor may offer a free trial version of the Software with a limited duration (currently 14 calendar days from first launch, subject to changes announced on the Site).

• During the Trial, the User has access to the full functionality of the Software for personal evaluation, without requiring a paid license key.
• Trial exports carry a periodic level mark. While the Trial is active, every file written by the Software's recording/export function contains a periodic level mark: a short attenuation (approximately −12 dB) every 30 seconds, starting 15 seconds into the file. Real-time monitoring, the meters and the on-screen verdict are not affected — what the User hears during the Trial is what a licensed build produces — but a file exported under the Trial is not intended for publication. The Software discloses this before each recording (recording menu and an on-screen notice when recording starts). Files exported under a Standard or Pro license are never marked.
• The Trial license is personal, non-exclusive, non-transferable, non-commercial and time-limited. It does not authorize sustained commercial production use once the Trial period ends.
• After the Trial period expires, the Software will stop processing audio and will require a paid license to continue.
• The Licensor may modify or withdraw the Trial at any time without affecting paid licenses already acquired.
• Attempting to circumvent Trial expiration mechanisms (modifying the system clock, deleting state files, reinstalling to reset the counter, etc.) is a material breach of this EULA.

2.ter BETA License (private testing phase)

The BETA build of the Software (v1.2 BETA) is distributed under a private, limited BETA license for invited testers only:

• The BETA license auto-expires on 5 September 2026 (internal flag MM_BETA_EXPIRY_ENABLED, at 23:59:59 local time), after which the BETA build will stop processing audio.
• This expiry applies to BETA builds only. Builds distributed through the commercial sales channel do not carry the expiry check and never stop working because of a date.
• During this BETA phase the Trial modality (§2.bis) runs for the same 14 calendar days as in the commercial build; no extended trial applies.
• Use is granted solely for evaluation, stability testing, DAW compatibility validation, and feedback to the Licensor. Commercial production use of the BETA build is not authorized, without prejudice to the User's ability to use the audio produced at their own risk.
• Redistribution, publication, public commercial review, published benchmarking, or reverse engineering of the BETA build is expressly prohibited.
• BETA license keys are nominative, issued in limited numbers, and may be revoked by the Licensor at any time without compensation.
• The Licensor invites bug reports, suggestions, and feedback at support@monkeymastering.com. By submitting feedback, the User grants the Licensor a non-exclusive, perpetual, irrevocable, royalty-free, worldwide license to incorporate it into the Software.
• The full commercial launch (Standard 9,90 € · Pro 18,90 € launch price) through the official sales channel (Lemon Squeezy as Merchant of Record, planned) is pending and will be announced on the Site. Those are the prices actually charged; no higher previous price is displayed as a reference.

3. Restrictions

The User SHALL NOT:

1. Copy, distribute, resell, rent, sublicense, lend, or transfer the Software or the license key to third parties.
2. Modify, adapt, translate, create derivative works, reverse engineer, decompile, or disassemble the Software, except to the extent mandatorily permitted by applicable law (Art. 100 et seq. of the Spanish TRLPI and equivalent provisions).
3. Remove, alter, or obscure proprietary, copyright, trademark, or identifier notices in the Software, including the JUCE splash screen required by the JUCE Personal license (see §12).
4. Use the Software for illegal, fraudulent purposes, the creation of unlawful content, or in violation of third-party rights.
5. Use the Software as part of a third-party SaaS, IaaS, or "online auto-mastering" service without a specific written agreement with the Licensor.
6. Share the license key, allow it to be used simultaneously on more Systems than authorized, or disclose the key to third parties.
7. Attempt to circumvent the Software's activation, license validation, activation limit, BETA expiration, or any other protection mechanism.
8. Remove, disable, or bypass the license manager or the BETA expiration check.

Third-party components — LGPL carve-out. The restrictions in this Section 3 (in particular clause 3.2) apply only to the extent permitted by applicable law and by the licenses of the third-party components incorporated in the Software. In particular, the Software includes the LAME MP3-encoding library (libmp3lame), licensed under the GNU Lesser General Public License v2.1 ("LGPL"): nothing in this EULA limits or supersedes the rights that the LGPL grants the User with respect to that library, including modification of the library, its replacement with an interface-compatible modified version, and decompilation or reverse engineering of the Software to the extent necessary to debug such modifications or to achieve the interoperability safeguarded by law (Art. 100 TRLPI; Art. 6 Directive 2009/24/EC). Third-party components are governed by their own licenses — see §12 and the THIRDPARTY.md file; the full LGPL text is distributed with the Software (LGPL-2.1.txt).

4. Activation and license validation

• During the private BETA (§2.ter), BETA license keys are validated locally without network calls. No activation or validation data is transmitted to any server.
• After the commercial launch, the Software will require online activation on first launch, which validates the license key against the payment provider and Merchant of Record (planned: Lemon Squeezy — api.lemonsqueezy.com), acting as issuer and verifier of the keys on behalf of the Licensor.
• After initial activation, the Software does not perform periodic communication with the Licensor's servers or those of the payment provider. Subsequent validations are performed locally (integrity check at startup). Network traffic only occurs during explicit activation, deactivation, or re-validation actions initiated by the User.
• The User may deactivate an installation from within the Software or by requesting assistance at support@monkeymastering.com, to free up an activation for use on another System.
• Each paid license allows up to two (2) simultaneous activations, configured on the payment provider's platform.
• Loss or leak of the license key is the User's responsibility. If unauthorized third-party use is suspected, contact support@monkeymastering.com immediately.

5. Intellectual property

• The Software is a work protected by copyright under the Spanish Consolidated Text of the Intellectual Property Law (Royal Legislative Decree 1/1996) and applicable international treaties.
• The Licensor retains full ownership of the Software at all times, including but not limited to: source code, binaries, DSP algorithms, factory presets, user interface design, trademarks, logos, iconography, and documentation.
• The MONKEY MASTERING trademark and its graphic elements, together with the slogan "NOT A PLUGIN. AN ENGINEER.", are owned by the Licensor (and may be registered under applicable law).
• The User retains full ownership of their audio, projects, and any content produced with the Software. The Licensor makes no claim over audio processed by the User.
• No intellectual property rights are granted to the User beyond the limited right of use described in this EULA.

5.bis Third-party trademarks (nominative / descriptive use)

The Software references, solely for descriptive and interoperability purposes, names of third-party platforms — in particular Spotify®, Apple Music®, YouTube™, Tidal®, SoundCloud™, Beatport®, Amazon Music® and Deezer® (distribution/streaming platforms to which optimized masters are exported), and names of competitor products cited in comparative materials on the Site (e.g. iZotope Ozone®, FabFilter Pro-L®, Sonible smart:limit®, LANDR®).

• All such trademarks are the property of their respective owners.
• The Licensor has no affiliation, sponsorship, endorsement, or association of any kind with the owners of those trademarks.
• The use is made under the doctrine of nominative / fair use (Art. 14 Directive (EU) 2015/2436; Art. 14 EU Trade Mark Regulation 2017/1001; analogous US law on nominative fair use): (a) naming the third-party product or service is necessary to indicate the intended target of the preset or the comparative reference; (b) the use is limited to what is strictly necessary; (c) it is made in accordance with honest commercial practices; (d) it does not suggest any commercial connection.
• Factory presets and export targets named "Spotify Ready", "Apple Music Ready", "YouTube Ready", "Tidal Ready", "SoundCloud Ready", "Beatport Ready", "Amazon Music Ready", and "Deezer Ready" refer to technical loudness and ceiling targets optimized for export to those platforms in accordance with each platform's public specifications, and do not imply certification, approval, or endorsement by them.

6. User content

• All audio processing happens locally on the User's System. The Software does not transmit, store, or analyze the User's audio, projects, or content on Licensor or third-party servers.
• Presets created by the User are owned by the User. They may be shared freely with third parties.

7. Updates and support

• The Licensor may offer Software updates. The conditions (free of charge, timeframe, edition) are detailed in the Terms of Sale.
• By installing an update, this EULA is understood to apply to the new version as well. If an update materially modifies the terms, the Licensor will inform the User and require express acceptance.
• Technical support is provided by email to support@monkeymastering.com, with the limitations described in the Terms of Sale. Support is best-effort and the Licensor does not commit to a specific response time; this does not affect the statutory warranty of conformity (§8).

8. Warranty

8.1 Legal warranty of conformity

For EU consumers, the statutory warranty of conformity under the TRLGDCU and EU Directive 2019/770 applies, as detailed in the Terms of Sale. Under Spanish Law 11/2023, the conformity period for digital content is two (2) years from delivery.

8.2 "AS IS" — limitations

Beyond the mandatory statutory warranty, the Software is provided "AS IS" and "AS AVAILABLE", without any additional warranties of any kind, express or implied, including but not limited to:

• Warranties of merchantability, fitness for a particular purpose, or non-infringement.
• Warranty that the Software will operate uninterruptedly, error-free, or compatibly with any specific hardware or software configuration of the User.

The User is solely responsible for assessing whether the Software meets their needs and system.

9. Limitation of liability

To the maximum extent permitted by applicable law, and subject to the caps set by Art. 148 TRLGDCU and other mandatory consumer-protection rules, the Licensor's total liability to the User for any claim arising out of or relating to the Software shall be limited to the price actually paid by the User for the license in the twelve (12) months preceding the event giving rise to the claim.

In no event shall the Licensor be liable for indirect, incidental, special, consequential, or punitive damages, including (without limitation):

• Loss of profits, revenue, business opportunities, clients, or reputation.
• Loss or corruption of audio, projects, sessions, or any User content.
• Business interruption.
• Cost of substitute goods or services.

This limitation does not apply to: - Willful misconduct or gross negligence of the Licensor. - Personal injury. - Liabilities that cannot be excluded or limited under mandatory consumer-protection law.

The User acknowledges that the limitations in this clause are an essential element of the license price.

10. Indemnification

The User agrees to hold the Licensor harmless from any third-party claim arising from:

• Use of the Software by the User in breach of this EULA or applicable law.
• Content processed by the User that infringes the intellectual property, image, privacy, or other rights of third parties.

11. Duration and termination

• This EULA remains in force for the duration of the User's license.
• The Licensor may immediately terminate the license in case of material breach of this EULA by the User (especially piracy, redistribution, circumvention of protection measures, or BETA-expiry bypass), with deactivation of the key.
• Upon termination, the User must cease all use of the Software and delete all copies.
• Clauses on intellectual property, limitation of liability, indemnification, governing law, and jurisdiction shall survive termination.

12. Third-party software and attributions

The Software incorporates the following third-party components, whose licenses the User agrees to respect:

• JUCE Framework (Raw Material Software Ltd.) — used under the JUCE Personal license (free tier), applicable while the Licensor's gross annual revenue derived from the Software does not exceed 50,000 USD. In compliance with that license, the Software displays a JUCE splash screen at startup, which the User may not remove, hide, or disable. Full license at https://juce.com/juce-8-license/. If revenue exceeds the threshold, the Licensor will migrate to the JUCE Indie tier or higher before the next released version.
• STFT / FFT algorithms used in the DSP chain are classical public-domain algorithms (Cooley–Tukey and variants).
• LAME MP3 encoder (libmp3lame) (© The LAME Project — lame.sourceforge.io) — used, unmodified and without its GPL-licensed decoder, for the MP3 export feature, under the GNU Lesser General Public License v2.1 (LGPL). Nothing in this EULA restricts the rights granted by the LGPL with respect to this library (see the carve-out in §3). The full LGPL text is distributed with the Software (LGPL-2.1.txt) and available at gnu.org; the library's source code and build flags are available at monkeymastering.com/lame-source.html and on request at legal@monkeymastering.com.
• No other third-party runtime dependencies beyond those listed above and those shipped with JUCE. Attributions and licenses are available in the Software's "About" / "Credits" section and/or in the THIRDPARTY.md file included with the installer.

12.bis AI use and algorithmic analysis

The Software is not an "AI system" within the meaning of Article 3.1 of Regulation (EU) 2024/1689 on Artificial Intelligence (EU AI Act):

• Analysis and mastering are performed by deterministic Digital Signal Processing (DSP) algorithms: FFT, Harmonic-Percussive Source Separation (HPSS), Wiener filters, biquads, and classical spectral heuristics with preconfigured parameters.
• No trained machine-learning models (neural networks, deep learning, statistical models trained on large corpora, etc.) are used in the audio processing chain.
• No automated profiling of the User is performed within the meaning of Art. 22 GDPR, nor are decisions with legal or significant effects taken on the basis of personal data.
• No personal data of the User or User audio is used to train any model, neither the Licensor's nor third-party.

For details see AIUseDisclosure.en.html.

13. Regulatory compliance and export control

The User agrees to comply with all applicable law relating to the use of the Software, including EU, United States, and any other relevant jurisdiction's export-control rules. The Software may not be exported or re-exported to persons or countries subject to sanctions or embargoes.

14. Data protection

The processing of personal data associated with the activation and use of the Software is governed by the Privacy Policy.

15. Assignment

The User may not assign this EULA or their rights or obligations hereunder without the prior written consent of the Licensor. The Licensor may assign this EULA to third parties in connection with a corporate reorganization, merger, or sale of assets, with notice to the User.

16. Entire agreement

This EULA, together with the Terms of Sale and the Privacy Policy, constitutes the entire agreement between the parties regarding the Software and supersedes any prior agreement, oral or written.

If any provision of this EULA is held void or unenforceable by a competent court, the remaining provisions shall remain in full force.

17. Governing law, language, and jurisdiction

• This EULA is governed by Spanish and European Union law.
• For consumers: courts of the consumer's domicile (Art. 90.2 TRLGDCU).
• For non-consumers / professional users: courts of the city of the Licensor's domicile.
• This EULA is published in Spanish (original version) and English (courtesy translation). In case of discrepancy between versions, the Spanish version prevails, without prejudice to any mandatory rights of the consumer under their national law.

17.bis Modifications to this EULA

The Licensor may modify this EULA to reflect legal, technical, or operational changes. Material modifications will be communicated to the User at least 30 days before they take effect, by email to the address associated with the active license and/or by prominent notice on the Site. Continued use of the Software after the new version takes effect constitutes acceptance. If the User does not accept the new terms, they may terminate the license and, where applicable, request a proportional refund pursuant to applicable law.
