Eventual RSVP – Tickets Licence

Version 1.1, 2026-11-13

1. Parties and definitions

Licensor: Jaap Vermeulen, trading as Vermeulen Solutions, Chemin du Courtil 9, 1241 Puplinge, Geneva, Switzerland.

Licensee: the person or organisation that buys a licence, or on whose behalf one is bought.

“The software” means Eventual RSVP – Tickets: the EmDash plugin and the site components published with it, in source and built form, in any version.

“Site” means one EmDash installation together with the hostnames that serve it, for example club.ch and www.club.ch.

“Production host” means any hostname that serves the public, other than the development and preview hosts listed in §3.

“Release” means a version of the software published to npm or the EmDash registry, with the release date shown in its changelog or registry entry.

“Business” means a licensee that uses the software in connection with its trade, business, craft or profession.

“Consumer” means a licensee that uses the software wholly or mainly for personal or family use.

“Paddle” means Paddle.com Market Limited and its affiliates.

“Privacy Policy” means the privacy page published on the software’s website.

“Support page” means the support page published on the software’s website.

2. Acceptance

The licensee accepts this licence by completing the purchase through Paddle or by installing or using the software on a production host, whichever happens first.
If the licensee does not accept this licence, it must not use the software outside §3.
A person who buys for an organisation confirms that they have authority to bind that organisation. An agency that buys for a client site confirms that it has authority to bind the client in respect of that site.

3. Trying it without a licence

Anyone may install and use the software without a licence, free of charge, on development and preview hosts: localhost, 127.0.0.1, [::1], and any host ending in .localhost, .workers.dev or .pages.dev.
The exemption is for development, testing and preview only. A copy used under this section must not sell tickets, issue tickets to the public or take public bookings, and must not use a preview hostname to serve the public.
Every other use needs a licence. The licensor may treat a public site on an exempt host as unlicensed if it is used to sell tickets, issue tickets or take public bookings.

4. What a licence covers

A site licence covers one site.
A ten-site licence covers up to ten sites that the licensee owns, or builds or runs for clients.
An unlimited licence covers any number of sites that the licensee owns, or builds or runs for clients.
Each licence also covers any number of staging, preview and development copies of a licensed site that do not sell to the public.
A client’s site that is covered by an agency’s ten-site or unlimited licence stays covered only while that licence is active for it. If the client and the agency part ways, the client needs a licence of its own for versions released after that, and may continue to use versions released during the term under §6.5.
An agency that buys for client sites confirms that it has authority to bind each client to this licence and must give each client a copy of these terms. When the agency stops managing a client site, it must deactivate that site on its licence and tell the client to obtain its own licence for new versions. The agency remains liable for the fees for sites it added.

5. Price, Paddle and taxes

The prices are:

Licence	Price per year
Site licence	USD 30
Ten-site licence	USD 100
Unlimited licence	USD 200

Prices are in United States dollars and exclude taxes.
Licences are sold through Paddle, which acts as reseller and merchant of record: Paddle takes the payment, adds the taxes that apply in the buyer’s country, and issues the invoice. Paddle’s buyer terms apply to the payment. This licence governs the software licence. If Paddle’s terms conflict with this licence on the software licence, this licence prevails; if they conflict on payment, Paddle’s terms prevail.
Where the checkout shows an amount in another currency, that amount is a conversion of the dollar price at the time of payment.
The licensor takes no share of ticket sales. Fees charged by Stripe or any other payment provider for the licensee’s ticket sales are between the licensee and that provider.
A licence does not renew by itself. The licensee renews by buying a further year. The price at renewal is the price published at that time; an active term is not affected by a later price change.
If a payment is reversed by a chargeback or similar payment dispute, the licence ends unless the licensee pays the amount again. Access may be suspended while the dispute is investigated.

6. Term, licence keys and what happens when a licence ends

A licence runs for one year from the day of purchase. It does not renew by itself; the licensee renews by buying a further year.
For each licence the licensor issues a licence code, sent by email after the purchase. The licensee activates each licensed site with the code, from that site’s Tickets administration page. The software then receives a licence key for the site’s hostname and its www variant. A key states the hostnames it covers and the date until which the licensee receives new versions. The licensee may not have more sites active at once than the licence covers.
The licensee may deactivate a site, from that site or from the licensor’s licence page, to activate another site in its place. A key keeps working on its site after deactivation, so a licence may be moved at most three times per site it covers in any twelve months; an unlimited licence may be moved without limit. If the code does not arrive or is lost, the licensee can have it sent again to the purchase email address.
The software checks the key on the site itself. It contacts the licensor’s licence service only when an administrator activates, refreshes or deactivates the licence, and then sends only the licence code and the site’s hostname. It never sends attendee, buyer or order data. The licensee is responsible for keeping the code and keys confidential.
A licensed site keeps working after the licence ends. The licensee keeps the right to use, on the hostnames named on the key and without limit in time, every version of the software released on or before the last day of the term. Only versions released after that day need a renewed licence.
Without a valid key for its hostname, a site outside §3 cannot start new ticket orders or checkouts, including free tickets. Orders that already exist keep working in every case: buyers can open them, tickets can be checked at the door, and refunds and cancellations can be handled.
If the licensor ceases to operate, existing keys and the versions released during the term continue to work on the hostnames they name. No new activations or keys can be issued after that point.

7. Updates and support

While a licence is active the licensee may use every new version of the software.
Support is by email, in English or French, at the address shown on the Support page. The licensor aims to answer within two business days but does not guarantee a response time, and is not obliged to add features or to adapt the software to a particular site.
Support covers installation, configuration, licence-key and defect questions. It does not cover custom development, site building, theme changes, the licensee’s Stripe account, or third-party services.
The licensor may change the support channel; the Support page is the current contact.

8. What the licensee may do

Install, configure and use the software on the licensed sites.
Change the source code for use on those sites.
Let employees and contractors work on those sites on the licensee’s behalf, provided they are bound by confidentiality and use restrictions at least as protective as this licence.
Make backup copies.
Use a ten-site or unlimited licence for client sites, subject to §4.5 and §4.6.

9. What the licensee may not do

Give, sell, sublicense or publish the software or a changed version of it to anyone else, in source or built form. Installing it on a client’s site under a ten-site or unlimited licence is allowed.
Share, sell or publish a licence code or key, use a key for a site it was not issued for, or have more sites active at once than the licence covers.
Remove or change the licence check in order to use the software on a site without a licence.
Offer the software to third parties as a hosted service beyond the licensed sites. A hosted service includes any managed or subscription service that gives third parties access to the software’s ticketing functions.
Remove copyright or licence notices.
Use the Eventual RSVP name or logo to imply endorsement, partnership or sponsorship without written permission. A truthful reference to the software is allowed.
Use the software in breach of applicable law.

If the licensee materially breaches §8 or §9 and does not put it right within 30 days of being asked in writing, §13 applies.

10. Open-source and third-party components

The software includes eventual-capacity, which is published under the MIT licence. The MIT licence continues to apply to that code.
The software includes or depends on third-party components listed in THIRD_PARTY_NOTICES.md. Their licences apply to those components.
Nothing in this licence restricts rights granted by a third-party licence. If a third-party licence conflicts with this licence, the third-party licence prevails for that component.
Eventual RSVP – Core (the events plugin) and Eventual RSVP – Registrations are separate software under the MIT licence and are not covered by this licence.

11. No warranty, liability

The software is provided as it is. The licensor does not promise that it is free of errors, that it fits a particular purpose, or that it will keep working with future versions of EmDash, Stripe or any other third-party service.
The licensee is responsible for its own ticket sales: prices, taxes, invoices, refunds, its contract with its buyers and with its payment provider, and its duties under data-protection law for the personal data of its buyers. The licensor is not a party to the licensee’s ticket sales and does not receive the personal data of the licensee’s ticket buyers.
The licensee must back up its data. To the extent the law allows, the licensor is not liable for lost or corrupted data.
Business licensees. To the extent the law allows, the licensor is not liable for lost sales or profit, lost or wrong payments, refunds, chargebacks, lost data or any indirect or consequential loss. The licensor’s total liability to a Business licensee is limited to the amount the licensee paid for the licence in the twelve months before the event that gave rise to the claim.
Consumer licensees. To the extent the law allows, the licensor is not liable for indirect or consequential loss. The licensor’s total liability to a Consumer licensee for direct loss is limited to the greater of the amount the licensee paid for the licence in the twelve months before the event that gave rise to the claim, or CHF 1,000.
Carve-outs. Nothing in this section limits liability for unlawful intent, gross negligence, fraud, death or personal injury, product liability under the Swiss Product Liability Act, or any other liability that mandatory law does not allow to be excluded or limited.
Third-party claims. A contractual limitation between the licensor and the licensee does not limit the statutory rights of the licensee’s ticket buyers or other third parties. The licensor’s liability to a third party is governed by the applicable law, not by this licence.
Nothing in this licence excludes liability that Swiss law or mandatory consumer law does not allow to be excluded.

12. Refunds and chargebacks

The licensee may ask for a full refund within 30 days of a purchase, without giving a reason, by writing to the support address shown on the Support page and including the Paddle receipt or order reference.
The refund is paid back through Paddle to the payment method used. The licence ends when the refund is paid, not when it is requested.
After the refund, the licensee must stop new ticket orders and checkouts. Existing orders, tickets, door check-in, cancellations and refunds to the licensee’s own buyers continue to work.
Nothing in this section limits a statutory withdrawal or refund right. A Consumer in the EU/EEA or the UK has the statutory 14-day withdrawal right provided by Paddle’s buyer terms; the 30-day policy in this section is additional. A Swiss Consumer has the rights that Swiss law provides; Swiss law does not create a general online withdrawal right.
If a payment is reversed by a chargeback or similar dispute, the licence ends unless the licensee pays the amount again. Access may be suspended while the dispute is investigated.

13. Termination for breach

If the licensee materially breaches §5, §8 or §9 and does not cure the breach within 30 days of written notice, the licensor may terminate the licence.
Termination ends the licensee’s right to receive new versions and to start new ticket orders or checkouts.
Survival for ordinary breaches. If the breach is not a deliberate circumvention of the licence check and not a failure to pay, the licensee may continue to use the versions released on or before the termination date on the licensed hostnames, provided it complies with §8–§10 and has paid all amounts due. Existing orders, tickets, check-in and refunds continue under §6.6.
Deliberate circumvention, piracy or non-payment. If the licensee deliberately circumvents the licence check, deliberately shares or publishes the software, a licence code or a key, or fails to pay, all rights under this licence end, including the right to use versions released during the term.
Termination does not affect amounts already due, the rights of the licensee’s ticket buyers, or any provision that by its nature survives.
The licensor may suspend new ticket sales while it investigates a material breach. It must restore them if the breach is cured.

14. Data protection and records

The software runs on the licensee’s site. The licensee is the controller of attendee and ticket-buyer data. The licensor does not receive that data.
For licence purchases, Paddle provides the licensor with the buyer’s name, email address and country, the business name if the buyer gives one, and the licence bought. When a site is activated, refreshed or deactivated, the licensor’s licence service receives the licence code and the site’s hostname. The licensor uses this data to issue codes and keys, provide support and keep licence records, as described in the Privacy Policy.
The licensee is responsible for its own privacy notices, retention periods, erasure requests and data-protection duties.
The licensor keeps licence records and invoices for ten years after the end of the financial year, as required by Swiss accounting law. Other personal data is kept as described in the Privacy Policy.

15. Changes to these terms

The licensor may publish a new version of these terms. A new version applies to purchases and renewals made after its publication.
A term already paid for keeps the version it was bought under.
A price change applies to future purchases and renewals; it does not change an active term.

16. Governing law, jurisdiction and language

These terms are governed by Swiss law, to the exclusion of its conflict-of-laws rules and of the United Nations Convention on Contracts for the International Sale of Goods.
Business licensees. The courts of Geneva, Switzerland, have exclusive jurisdiction.
Consumer licensees. A Consumer may bring proceedings at the Consumer’s domicile or habitual residence or at the licensor’s seat in Geneva. Nothing in this clause prevents a Consumer from bringing a claim before a court that mandatory consumer law makes available.
Language. This licence is concluded in English. A French translation is published for convenience. For a Consumer whose habitual residence is in a French-speaking jurisdiction, the French version prevails to the extent mandatory law requires it; otherwise the English version prevails. If the versions conflict, the version that is more favourable to the Consumer applies to the extent mandatory law requires it.
For EU/EEA Consumers, the jurisdiction and consumer-protection rules of the Lugano Convention and mandatory EU consumer law are unaffected.

17. General

Entire agreement. This licence, the Privacy Policy and Paddle’s buyer terms are the entire agreement for the software licence and the purchase. If they conflict, this licence governs the software licence, Paddle’s terms govern the payment, and the Privacy Policy describes data processing.
Severability. If a provision is invalid or unenforceable, the rest of the licence remains in force.
No waiver. A failure or delay in enforcing a right is not a waiver of that right.
Assignment. The licensee may not assign or transfer the licence without the licensor’s written consent. The licensor may assign the licence with the business or to a successor.
Notices. Notices to the licensor go to the support address on the Support page. Notices to the licensee go to the email address used for the purchase.
Force majeure. Neither party is liable for a delay caused by an event beyond its reasonable control.
No third-party rights. No third party has rights under this licence. Paddle’s buyer terms are a separate agreement between Paddle and the buyer.
Survival. Sections 10 to 17 survive termination.
Electronic acceptance. The licence may be accepted electronically. The records of Paddle and the licensor are evidence of the purchase and acceptance.
