Terms of Use
1. Who we are and what these terms cover
ThunderYak is provided by Artur Tkachenko, trading as Climb that App, Schützenstraße 29, 83646 Bad Tölz, Germany (“we”, “us”). These terms apply to the ThunderYak iPhone app and to thunderyak.com.
You get the app from Apple’s App Store, so Apple’s Licensed Application End User License Agreement also applies. These terms add to it. Where the two differ, Apple’s agreement governs your relationship with Apple, and these terms govern your relationship with us.
2. What ThunderYak does
ThunderYak describes how the guitar tone of a recorded song was made (guitar, pickup, amp, effects, tuning and settings) and suggests settings for the gear you tell it you own.
- Song research is compiled from public sources such as interviews, rig rundowns and articles, with the help of AI models. The app shows the sources it used.
- Settings for your gear are generated with the help of AI models from that research and the gear profiles in our catalogue.
- ThunderYak doesn’t record, play or process audio, and doesn’t connect to or control your equipment.
3. Information, not a guarantee
We work to make research and settings accurate, but they are a starting point and can be incomplete or wrong. Public sources sometimes disagree, gear varies between units and years, and a guitar, amp and room never sound exactly like a studio recording. Use the settings at your own judgement and protect your hearing and your equipment, for example by starting at a low volume.
4. Free use and ThunderYak Pro
- You can download ThunderYak and try it for free, including settings for a limited number of songs on your rig. The app shows how many free songs you have left.
- ThunderYak Pro is an auto-renewing subscription that you buy through the App Store. Apple shows the price, the billing period and any free trial before you confirm.
- Apple charges your Apple Account. The subscription renews automatically unless you turn off renewal at least 24 hours before the end of the current period, in your iPhone’s Settings under your name and Subscriptions.
- To keep the service fair and affordable, free and Pro use have daily fair-use limits. If you reach one, the app tells you and you can continue the next day.
- We may change what Free and Pro include. If a change reduces what you’ve already paid for, it takes effect at your next renewal at the earliest, and we’ll tell you in advance.
5. Right of withdrawal and refunds
Apple sells the subscription to you. Apple’s terms therefore govern payment, any statutory right of withdrawal for digital content and services, and refunds. You can ask Apple for a refund at reportaproblem.apple.com.
6. Fair use of ThunderYak
Please don’t:
- copy, scrape or bulk-download research or settings, or use automated tools to access ThunderYak;
- get around usage limits, App Attest or other security measures, or pretend to be another installation;
- reverse engineer the app or our server, except where the law allows it;
- resell or publish ThunderYak content as your own collection.
We may limit or block access that breaks these rules.
7. Content and trademarks
The app, its design and its research and settings are protected by copyright. You may use them for your own playing and share individual settings with friends.
Song titles, artist names, album art and gear names and trademarks belong to their owners. ThunderYak isn’t affiliated with or endorsed by any artist, label or gear maker.
8. Other services and links
The app links to other sites, such as the sources of a song’s research, Songsterr and YouTube. We don’t control those sites and aren’t responsible for their content.
9. Availability and changes
We aim to keep ThunderYak running, but we can’t promise it will always be available or free of errors. We may improve, change or retire features. Research for a song may be updated, which can change its settings.
10. Liability
We are liable without limitation for intent and gross negligence, for injury to life, body or health, under the German Product Liability Act (Produkthaftungsgesetz) and for any guarantee we have given.
For slight negligence, we are liable only if we breach an obligation that is essential for the proper use of ThunderYak and on which you can normally rely (a cardinal obligation). In that case our liability is limited to the typical damage we could foresee when you started using ThunderYak.
Otherwise, our liability is excluded. These limits also apply to the people who work for us.
11. Ending use
You can stop using ThunderYak at any time by deleting the app. Deleting the app doesn’t cancel a subscription; cancel it in your iPhone’s Settings. We may end or suspend access if you seriously or repeatedly break these terms.
12. Changes to these terms
We may update these terms, for example when ThunderYak or the law changes. We’ll announce important changes in the app or on this page before they take effect. If you keep using ThunderYak after that, the new terms apply.
13. Applicable law
German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer, you keep the protection of the mandatory laws of the country where you live.
14. Disputes
We are neither obliged nor willing to take part in dispute resolution proceedings before a consumer arbitration board. If something goes wrong, please write to us first at hello@thunderyak.com.
