Short, and in plain language. If anything here is unclear, ask me before you apply rather than after.
20% of the sale price on every sale you refer, for ARGISH, SILT, REHEAT, THALM and the Collection. The percentage is taken on the price the customer actually pays, so if they buy at a discounted or introductory price, the commission is 20% of that.
Those five are the whole catalogue, so there is nothing on sale that you cannot earn from.
Gumroad does, directly. I never hold your money. You will need a Gumroad account with your payout details filled in, and the email address on that account is the one I use to set you up.
Gumroad pays out once your balance passes $100. That is Gumroad's threshold, not mine, and I cannot waive it. On a $29 instrument that is a few sales before your first payment arrives, so it is worth knowing at the start.
Every instrument carries a 30-day money-back guarantee. If a customer you referred takes a refund, the commission on that sale is reversed. If you have already been paid for it, Gumroad deducts it from your balance, which can put the balance into the negative until later sales clear it.
This is not a penalty, it is just how a refund works. It is also why recommending these to people they genuinely suit serves you better than volume.
Your link sets a cookie in the buyer's browser that lasts 30 days. If they buy within that window, the sale is credited to you.
Being straight about what that does not cover, because I would rather you were not surprised:
I have no way to recover a sale that did not track, and neither does Gumroad. If you think something has gone wrong at my end rather than the buyer's, tell me and I will look properly.
This one is not optional. Disclose the affiliate relationship clearly wherever you post the link, in the video, the description, or the text itself. In the US the FTC requires it, in the UK the ASA requires it, and most other places have an equivalent rule. It protects you more than it protects me, and an audience that finds out later is an audience you have lost.
You are free to be critical, to compare these unfavourably with something else, or to conclude they are not for your audience. I will not pull your account over an honest opinion. Do not invent features, quote specifications that are not real, or promise things the instruments do not do.
You may use the product names, screenshots and audio from the site in your coverage. Please do not modify the logo or make your own Tunary branding.
Either of us can end this at any time, for any reason or none, by saying so. If I end it, any commission properly earned before that point is still paid.
I may change the commission rate or which products are included. If I do, I will tell existing affiliates first, and the change will not be applied backwards to sales already made.
These terms are written in plain language deliberately. They set out how the programme works between you and Tunary Instruments, and they are not legal advice.
Your Gumroad account, your payouts and any tax you owe on what you earn are between you and Gumroad, and are covered by Gumroad's own terms. You are responsible for your own tax.
Nothing here makes you an employee, a partner or an agent of Tunary Instruments.
Questions, or something here that does not sit right with you: james@tunary.io. I answer these myself.
