Terms of Use

For event guests

How it works. Mixtape lets you request a song at an event and back your request with a charitable donation. Requests are suggestions to the event’s host or DJ, who decides what plays. Your donation supports the charity you choose whether or not the song plays. Donations never purchase queue position, priority, or a guarantee that any song will be played — this includes adding a donation to a song that’s already been requested.

Where your money goes. Donations are made to Every.org, a 501(c)(3) nonprofit organization (EIN 61-1913297), which grants funds to the charity you choose. Your tax receipt comes from Every.org. 0% platform fee on charity. Forever. — Mixtape takes nothing from charitable donations. We never hold or transmit your funds.

Refunds. Because donations are made to and processed by Every.org, refund and dispute questions are handled by Every.org, not by Mixtape. Contact Every.org support with your receipt. A refunded donation does not create any obligation regarding song requests, and a played song does not affect your rights regarding your donation.

Dedications and conduct. If you opt in, your name and message may be shown on the event screen and recap page. Keep messages appropriate for a mixed audience; the host may decline or remove any request or dedication at any time, without notice and without explanation. Don’t use Mixtape to harass anyone or to post unlawful content.

Tax. We don’t provide tax advice. Your receipt from Every.org and your own tax advisor are your sources on deductibility.

Age. You must be 13 or older to use Mixtape.

Optional event text updates

Yara via Mixtape is an optional SMS program for reminders and logistics about Yara’s September 19, 2026 event, operated through Mixtape by Efficient Frontier Labs, LLC. Check the separate SMS permission box on the event text signup page to request these messages at your own US mobile number. You can RSVP and attend without agreeing to texts. Permission is limited to this event’s logistics; donation solicitations, marketing and other events are not included.

Message frequency varies. Message and data rates may apply. When texts are active, reply STOP to unsubscribe or HELP for help. You may also use your private opt-out link at any time or contact andrew@efficientfrontierlabs.com for support or to withdraw consent. Signing up again on the web does not automatically reverse an opt-out. Wireless carriers are not liable for delayed or undelivered messages. Signup currently records permission while text delivery is being set up; it does not guarantee that a text will be sent.

For event hosts

Hosts connecting a Spotify account confirm that: the event is a private, non-commercial gathering; the Spotify account is your own (Premium) account used in accordance with Spotify’s terms; and you have whatever permissions your venue requires. You control playback and the request queue; Mixtape never plays, stores, or transmits audio. You can disconnect Spotify yourself at any time, from the account menu on your events page: disconnecting deletes the Spotify tokens we hold and ends our access to your account. Signing out is separate — it ends your session and leaves the connection in place. Disconnecting does not delete your events or your donation records; email andrew@efficientfrontierlabs.com for that.

Third-party services: Spotify

Mixtape uses the Spotify Platform so event hosts can control playback on their own Spotify account. By using Mixtape you agree that: (a) Spotify is a third-party beneficiary of these Terms and of our Privacy Policy and is entitled to directly enforce these Terms; (b) we make no warranties or representations on behalf of Spotify, and all implied warranties with respect to the Spotify Platform, Spotify Service, and Spotify Content — including implied warranties of merchantability, fitness for a particular purpose, and non-infringement — are expressly disclaimed; (c) you will not modify or create derivative works based on the Spotify Platform, Spotify Service, or Spotify Content; (d) you will not decompile, reverse-engineer, disassemble, or otherwise reduce the Spotify Platform, Spotify Service, or Spotify Content to source code or other human-perceivable form, to the fullest extent permitted by law; and (e) Mixtape — not Spotify or any other third party — is responsible for this product, and any liability of such third parties is disclaimed to the fullest extent permitted by law.

The service, plainly

Mixtape is provided “as is.” We work hard to make events run smoothly, but we don’t guarantee uninterrupted service, that any request will play, or any particular fundraising outcome. To the fullest extent permitted by law, Efficient Frontier Labs, LLC’s liability arising from use of the service is limited to the amount you paid us to use it (for guests and hosts today: zero). Nothing in these terms limits liability that cannot lawfully be limited.

These terms are governed by California law. Questions: andrew@efficientfrontierlabs.com.
