Riff Locker Beta Tester Agreement

Every beta tester accepts this agreement before an invitation is sent. It is the complete text; the sign-up flow shows exactly this wording and records which version you accepted.

Version 1.0 · Effective September 11, 2026 · Apply to the beta · Privacy Policy · App EULA

Plain-language summary. Keep the beta private: no sharing builds or invitations, no screenshots, recordings, posts or reviews. Anything you tell us about the app is ours to use; the music you make with it stays yours. The software is unfinished and may lose data, so keep backups. We can end the beta or your place in it at any time, and so can you. Typing your name is your signature. If the summary and the full text ever differ, the full text below controls.

Riff Locker Beta Tester Agreement

Version 1.0. Effective September 11, 2026.

This Beta Tester Agreement (the "Agreement") is a legal contract between Wildmann Design Studio, the business of Michael Wildmann Krauss-Lucas ("Wildmann Design Studio", "we", "us" or "our"), and you, the individual applying to test pre-release versions of the Riff Locker application ("you" or "Tester"). It governs your participation in the Riff Locker beta program (the "Beta Program"), including every pre-release build, feature, document and communication you receive as part of it.

By ticking the acceptance boxes, typing your name and pressing "I agree and sign", you accept this Agreement and confirm that you have the legal capacity to do so. If you do not agree to every term, do not apply and do not install any pre-release build.

1. Eligibility

You may take part only if all of the following are true:

  • you are at least 18 years old, or the age of majority where you live if that is higher;
  • you own or control an iPhone that meets the requirements we publish, and an Apple Account in your own name;
  • you agree to Apple's TestFlight terms and the Apple Media Services terms, which also apply to the delivery and use of pre-release builds;
  • you are not employed by, contracted to, or otherwise working on behalf of a company or project that develops or plans to develop music capture, passive listening, or audio analysis software, unless you have disclosed that to us in writing and we have accepted you anyway; and
  • you provide accurate information in your application.

We may accept or decline any application, and may remove any Tester from the Beta Program, at our sole discretion and without giving a reason.

2. Definitions

  • "Beta Software" means every pre-release version of the Riff Locker application and any related software, machine-learning models, audio-analysis components, sample content, documentation, release notes, surveys and materials that we make available to you through TestFlight or otherwise, including updates.
  • "Confidential Information" means the Beta Software and all non-public information relating to it or to us, whether disclosed in writing, orally, by demonstration or by your own use, including: unreleased features and designs; the behaviour, methods, parameters and performance of Whisper Mode, riff analytics, chord and progression detection, genre classification and any other analysis; screenshots, screen recordings, photographs and audio or video recordings of the Beta Software; defects, crash reports and test results; release plans, pricing plans and business plans; the identity of other Testers; and all communications from us in connection with the Beta Program. The existence of Riff Locker as a product and the information we publish on our website are not Confidential Information.
  • "Feedback" means every bug report, suggestion, idea, comment, survey answer, feature request, rating, description of your use, and other information you provide to us about the Beta Software or the Beta Program, in any form.
  • "Your Recordings" means the musical performances, compositions and other audio that you create or capture using the Beta Software, and the titles, notes, tags and other details you attach to them.

3. Limited license

Subject to this Agreement, we grant you a personal, non-exclusive, non-transferable, non-sublicensable, revocable license to install the Beta Software through TestFlight on iPhones that you own or control, and to use it solely to evaluate it and provide Feedback during the term of this Agreement. We reserve every right not expressly granted. No license is granted by implication, estoppel or otherwise.

4. Restrictions

Except as expressly permitted by this Agreement or by law that cannot be excluded by contract, you must not, and must not allow anyone else to:

  • copy, distribute, sell, rent, lend, sublicense, transfer or otherwise share the Beta Software, a TestFlight invitation, a build, or access to any of them;
  • install or use the Beta Software on a device you do not own or control, or allow any other person to use it;
  • reverse engineer, decompile, disassemble, decrypt, extract, or attempt to derive the source code, algorithms, thresholds, models, model weights, training data, audio-analysis parameters, file formats or protocols of the Beta Software, or otherwise attempt to discover how it works beyond ordinary use of its features;
  • extract, reuse, adapt or train on any machine-learning model, sample content, artwork, sound, text or other component of the Beta Software;
  • modify, translate, adapt or create derivative works of the Beta Software;
  • remove, obscure or alter any copyright, trademark, confidentiality or other proprietary notice;
  • circumvent or interfere with TestFlight, code signing, build expiry, device limits or any other technical control;
  • use the Beta Software, Confidential Information or Feedback to build, train, benchmark, specify or improve any product or service that competes with Riff Locker, or assist anyone else in doing so;
  • publish or share benchmarks, comparisons, accuracy measurements or performance results;
  • use the Beta Software to provide services to third parties, or for any commercial purpose other than your own music-making;
  • use the Beta Software to record any person without the consent that applicable law requires; or
  • use the Beta Software in violation of any law, or of Apple's terms.

5. Confidentiality

You must hold Confidential Information in strict confidence, use it only to take part in the Beta Program, and not disclose it to any person or entity. You must protect it with at least the care you use for your own confidential information, and never less than reasonable care. Without limiting the above, you must not post, publish, stream, present, describe, demonstrate or otherwise disclose the Beta Software or any Confidential Information on social media, in forums, chat servers, group messages, videos, podcasts, blogs, press, app-review sites, rating services, in person at gatherings, or through any other channel, and you must not take or share screenshots, screen recordings, photographs or audio or video recordings of the Beta Software.

Confidential Information does not include information that you can show, with written records: (a) was public at the time we disclosed it, or later became public through no breach of this Agreement; (b) was lawfully known to you before we disclosed it, without any obligation of confidence; (c) was lawfully received by you from a third party who had the right to disclose it without restriction; or (d) was independently developed by you without use of or reference to Confidential Information.

If you are required by law, regulation or court order to disclose Confidential Information, you must, where lawful, give us prompt written notice so that we can seek protection, disclose only what is legally required, and cooperate with us in limiting the disclosure.

Your obligations under this Section 5 continue during the Beta Program and for three years after it ends for you, and continue for as long as the relevant information remains a trade secret under applicable law. When the Beta Program ends for you, or at our request at any time, you must delete every pre-release build and every copy of Confidential Information in your possession, and confirm in writing that you have done so if we ask.

You acknowledge that a breach of this Section 5 or of Section 4 would cause us harm that money alone cannot repair, and you agree that we may seek an injunction or other equitable relief in any court of competent jurisdiction, in addition to any other remedy, without having to post a bond or prove actual damages.

6. No public statements

Until we tell you in writing that the confidentiality period has ended, you must not publish any review, rating, opinion, description or comparison of the Beta Software, and must not state publicly that you are testing it in any way that reveals Confidential Information. We may, at our discretion and in writing, permit specific public statements (for example on the day of a public launch); any such permission is limited to what it says.

7. Feedback

You agree that Feedback is given voluntarily and without expectation of payment. You hereby assign to Wildmann Design Studio all right, title and interest, including all intellectual property rights, in and to the Feedback, to the fullest extent permitted by law. To the extent any right in Feedback cannot be assigned, you grant us a perpetual, irrevocable, worldwide, royalty-free, fully paid-up, transferable and sublicensable license to use, reproduce, modify, distribute, display, perform, make, sell and otherwise exploit that Feedback for any purpose without restriction, attribution or accounting. To the extent permitted by law, you waive any moral rights in Feedback. We are under no obligation to use, keep confidential, or respond to Feedback, and we may develop products and features similar to your Feedback independently.

You represent that your Feedback is your own, that you have the right to provide it, and that it does not include confidential information or intellectual property of any third party.

Feedback does not include Your Recordings. You own Your Recordings. The Beta Software stores Your Recordings only on your device and we do not receive them unless you choose to send a recording to us. If you do send one, you grant us a non-exclusive, royalty-free, worldwide license to use it solely to test, diagnose and improve Riff Locker, and we will not publish it or use it in any other way without your written permission.

8. Ownership and intellectual property

As between you and us, Wildmann Design Studio and its licensors own all right, title and interest, including all copyrights, trade secrets, patent rights, trademark rights and other intellectual property rights, in and to Riff Locker, the Beta Software, Whisper Mode, the analysis methods and models, the designs, user interface, artwork, sounds, sample content, documentation, the Riff Locker website, and all Confidential Information and Feedback. "Riff Locker", "Whisper Mode", the guitar-pick logo and the locker artwork are trademarks of Wildmann Design Studio. Nothing in this Agreement transfers any ownership to you, and you may not use our trademarks without our prior written permission. Apple, iPhone, TestFlight, Logic Pro and GarageBand are trademarks of Apple Inc.; Apple is not a party to this Agreement and does not endorse Riff Locker.

9. Your data and privacy

The Beta Software keeps Your Recordings and related details on your device and contains no networking code that sends them to us. Apple's TestFlight service collects crash logs, usage information and feedback you submit through TestFlight and shares them with us under Apple's terms and privacy policy; you can limit that sharing in your device's TestFlight settings.

To run the Beta Program we collect, through our website, the information described in Section 15 and in our Privacy Policy: your name, email address, instrument, device details, the answers you give in your application, the IP address and browser information of the devices you use for the application and the acceptance, the times of those actions, and the acceptance record. We use this information to administer the Beta Program, to communicate with you, to protect the Beta Software and our rights, and to demonstrate that this Agreement was accepted. Our Privacy Policy at riff-locker.com/privacy.html explains your rights and how long we keep this information, and forms part of this Agreement.

10. Beta nature of the software; disclaimer of warranties

The Beta Software is pre-release. It may contain errors and defects, may be unstable, may stop working when a build expires, may change or lose features without notice, and may corrupt or lose data, including Your Recordings. It is not intended for production use or as the only copy of anything you care about. Keep independent backups.

Whisper Mode, riff analytics, chord and progression estimates, genre labels, similarity hints and every other analysis produced by the Beta Software are heuristic estimates. They may be wrong, they are provided for your information only, and they are not musical, legal or copyright opinions. You are solely responsible for how you use them.

TO THE FULLEST EXTENT PERMITTED BY LAW, THE BETA SOFTWARE, THE BETA PROGRAM AND ALL RELATED MATERIALS ARE PROVIDED "AS IS" AND "AS AVAILABLE", WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. WE DISCLAIM ALL WARRANTIES, EXPRESS, IMPLIED OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, AND THAT THE SOFTWARE WILL BE ERROR-FREE OR UNINTERRUPTED. We have no obligation to provide support, maintenance, updates, fixes or a public release, and we may end the Beta Program at any time.

11. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW, WILDMANN DESIGN STUDIO AND ITS OWNER, CONTRACTORS AND LICENSORS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF DATA, RECORDINGS, PROFITS, REVENUE, GOODWILL OR USE, ARISING OUT OF OR RELATED TO THIS AGREEMENT, THE BETA SOFTWARE OR THE BETA PROGRAM, HOWEVER CAUSED AND UNDER ANY THEORY OF LIABILITY, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. OUR TOTAL LIABILITY TO YOU FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THIS AGREEMENT WILL NOT EXCEED FIFTY UNITED STATES DOLLARS (US$50). Some jurisdictions do not allow some of these limitations; in those jurisdictions our liability is limited to the greatest extent the law permits.

12. Indemnity

You will defend, indemnify and hold harmless Wildmann Design Studio and its owner from and against any claims, damages, losses, liabilities, costs and expenses, including reasonable attorneys' fees, arising out of or related to your breach of Sections 4, 5, 6 or 7, your violation of any law or third-party right in connection with the Beta Program, or Your Recordings that you choose to send to us.

13. Term and termination

This Agreement starts when you accept it and continues until the earliest of: the date we end the Beta Program; the date we remove you from it; the date you withdraw by emailing us; or the date we tell you in writing that it has ended for you. Either party may end it at any time, for any reason, by written notice, which includes email. When it ends, your license terminates immediately, you must stop using and delete every pre-release build, and you must comply with Section 5. Sections 2, 4 through 8, and 10 through 17 survive termination.

14. Compliance with law; export

You must comply with all laws that apply to your use of the Beta Software, including United States export control and sanctions laws. You confirm that you are not located in, and are not a resident or national of, a country subject to a United States government embargo, and that you are not on any United States government list of prohibited or restricted parties.

15. Electronic acceptance and records

You agree that ticking the acceptance boxes, typing your name and pressing "I agree and sign" constitutes your electronic signature and creates a binding agreement under the United States Electronic Signatures in Global and National Commerce Act, the Uniform Electronic Transactions Act as adopted in the applicable state, and any other law that recognizes electronic signatures. We record, and you consent to our recording: the version and SHA-256 fingerprint of the agreement text you saw; the time of acceptance; the name you typed; the IP address and browser identification of the device you used; and the email address you verified. We email you a copy of the agreement and this record, and we keep the record for as long as needed to enforce this Agreement. You consent to receive all notices relating to the Beta Program electronically at the email address you verified, and you are responsible for keeping that address current.

16. Governing law and disputes

This Agreement is governed by the laws of the State of Washington, United States of America, without regard to its conflict-of-laws rules, and, to the extent applicable, the federal laws of the United States. The United Nations Convention on Contracts for the International Sale of Goods does not apply. Except where either party seeks injunctive or other equitable relief, which may be sought in any court of competent jurisdiction, the state and federal courts located in Pierce County, Washington have exclusive jurisdiction over any dispute arising out of or related to this Agreement, and each party consents to personal jurisdiction and venue there. Either party may bring an individual claim in small-claims court where permitted.

17. General

  • Entire agreement. This Agreement, together with the Privacy Policy and Apple's TestFlight terms, is the entire agreement between you and us about the Beta Program and replaces any earlier discussions or understandings.
  • Changes. We may publish a new version of this Agreement. Continued participation after we notify you by email, or after you accept the new version through the website, means you accept the new version; if you do not, you must withdraw. The version you accepted governs until then.
  • Assignment. You may not assign or transfer this Agreement or any rights under it. We may assign it, in whole or in part, to a successor of the Riff Locker business or to an entity we control.
  • Severability. If any provision is held unenforceable, it will be enforced to the maximum extent permitted and the remainder stays in effect.
  • Waiver. A failure to enforce any provision is not a waiver of it or of any other provision.
  • Relationship. You are an independent volunteer, not an employee, agent, partner or contractor of Wildmann Design Studio, and you are not entitled to any compensation.
  • Notices. Notices to you go to the email address you verified. Notices to us go to beta@riff-locker.com, with "Beta Tester Agreement" in the subject line.
  • Language. This Agreement is written in English; any translation is for convenience only.
