Terms and Conditions for Supporters

Last updated: 2026-09-04

§ 1 Provider and scope

The provider is Quavon UG (haftungsbeschränkt), Langbehnstraße 39, 83022 Rosenheim, Deutschland (“we”). These terms govern the supporter contract you conclude via jackpoll.org. Use of the Jackpoll application itself is governed by the terms at app.jackpoll.org.

Using Jackpoll is and remains free of charge and requires no supporter contract. Supporting is voluntary.

§ 2 What you get

In return for your contribution we list you on the supporters page in the tier your amount reaches. You also get an optional link beside your name; the higher tiers additionally allow a profile picture, a banner image and a short description. Your management page shows which fields your tier unlocks.

Your tier follows your lifetime total and is never downgraded if you later pay less. There is no claim to a particular placement, layout or duration of visibility.

§ 3 Conclusion of contract

The presentation of tiers on this website is not a binding offer. By choosing “order with obligation to pay” you make a binding offer. Directly above that button you see the essential characteristics, the total price, the billing interval and the term. The contract is concluded when your payment reaches our payment service provider; you then receive a confirmation by email.

§ 4 Prices and payment

All amounts shown are final prices in euro and include statutory VAT. No shipping or additional costs apply.

Payment is processed by Mollie B.V., Amsterdam. We never see or store card details. For monthly or yearly support we charge the amount at the start of each period using the payment method you set up. You receive an invoice for every payment at the billing address you provided.

Supporting is currently only possible with a German billing address.

§ 5 Term and cancellation

A one-time contribution creates no continuing obligation. Monthly or yearly support runs for an indefinite period and you may cancel it at any time with effect from the end of the current billing period. There is no minimum term and no notice period.

You can cancel using the cancellation button at /kuendigung, using the link in your confirmation email, or informally in text form to contact@quavon.de. Contributions already paid for a running period are not refunded pro rata; your listing remains until the end of that period.

We may terminate the contract with 30 days' notice to the end of a billing period. The right of either party to terminate for cause remains unaffected.

§ 6 Right of withdrawal

Consumers have a statutory right of withdrawal. The full withdrawal instruction and the model withdrawal form are at /widerruf.

§ 7 Your content

For the name, link, images and text you provide, you grant us the simple, revocable right to display them publicly on the supporters page. You warrant that you hold the necessary rights and that the content infringes no third-party rights and no laws.

We may remove unlawful, misleading or promotional content that plainly has nothing to do with supporting the project. Your listing then continues without the removed content, and you may terminate the contract for cause.

§ 8 Liability

We are liable without limitation for intent and gross negligence and for injury to life, body or health. In cases of simple negligence we are liable only for breach of a material contractual obligation and limited in amount to the foreseeable damage typical for this type of contract. Liability under the German Product Liability Act remains unaffected.

§ 9 Changes to these terms

We may amend these terms with effect for the future where there is a valid reason and you are not unreasonably disadvantaged. We announce the change by email at least 30 days in advance. If you do not object before it takes effect, the change is deemed accepted; we point this out separately in the announcement. If you object, the contract ends when the change takes effect.

§ 10 Final provisions

German law applies. If the supporter is a consumer habitually resident in another EU state, the mandatory consumer protection provisions of that state remain unaffected. Should a provision be invalid, the remainder of the contract stays in force.

We are neither willing nor obliged to take part in dispute-resolution proceedings before a consumer arbitration board (§ 36 (1) no. 1 VSBG).
