Online dispute resolution

The EU Commission provides a platform for online dispute resolution: ec.europa.eu/consumers/odr. We are neither obliged nor willing to participate in dispute-resolution proceedings before a consumer arbitration board.

01Terms of Service

1. Scope

These terms govern use of the MKV Player software and of any commercial license granted by David Schneider (“we”, “us”) via matroska.davidschneider.xyz.

2. The products

  • MKV Player for Nextcloud — a free app that plays Matroska files in the Nextcloud Viewer, shown with a small watermark.
  • Open-source engine & player — the WASM remux engine and video.js player, available under open-source licenses (see below).
  • Commercial licensing — commercial licenses (to remove the watermark, or to embed the engine/player in a closed-source product) are planned and are not currently sold online. They are arranged individually by written agreement; the terms of any such license are set out in that agreement.

3. No online sales at this time

There is currently no online checkout or payment on this site. Licensing enquiries are handled by email at licensing@davidschneider.xyz. If a paid checkout is offered in the future, the applicable purchase, payment, and delivery terms will be presented at that time.

4. License grant

Where a commercial license is granted by written agreement, we grant you a non-exclusive, non-transferable right to use it as described in that agreement. License keys (once issued) must not be shared, resold, or used on instances other than the one they were issued for.

5. Open-source components

The underlying software is available under open-source licenses (the EBML parser core under MIT; the player and remuxer under AGPL-3.0). A commercial license covers uses those licenses do not permit. Nothing in these terms limits your rights under the applicable open-source licenses.

6. Acceptable use

You are responsible for the content you play. The software runs in the viewer’s browser and we neither host nor process your media. Do not use the software to infringe third-party rights or applicable law.

7. Availability & warranty

The software is provided “as is”. Because keys validate offline, continued use does not depend on our servers. Statutory warranty rights for consumers remain unaffected.

8. Liability

We are liable without limitation for intent and gross negligence, and under mandatory law (including the Product Liability Act and for injury to life, body, or health). For slight negligence we are liable only for breach of a material contractual obligation, limited to foreseeable, typical damage. Any further liability is excluded.

9. Changes

We may update these terms; the version in force at the time of your purchase applies to that purchase.

10. Governing law

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. Mandatory consumer-protection provisions of your country of residence remain unaffected.

02Privacy Notice

Controller

David Schneider, Colmantstraße 39, 53115 Bonn, Germany — licensing@davidschneider.xyz.

1. What we process

  • Enquiry data: if you email us about licensing, we process your email address and the content of your message to respond.
  • License data: if a license key is issued to you, we process your email address and Nextcloud instance ID, generate an order ID, and issue the key. These are stored in Cloudflare Workers KV. (There is no online checkout at this time.)
  • Server logs: our hosting provider (Cloudflare) processes technical data such as IP address for security and operation.
  • On your device: if a key is issued to you, we store your order ID and key in your browser’s localStorage so you can retrieve it on a return visit. This never leaves your device and is not a tracking cookie.

2. Purposes & legal bases (Art. 6 GDPR)

  • Responding to your licensing enquiry — Art. 6(1)(b) (pre-contractual steps) / Art. 6(1)(f) (legitimate interest).
  • Issuing and delivering a license key, where applicable — Art. 6(1)(b).
  • Security and abuse prevention — Art. 6(1)(f) (legitimate interest).
  • Retention for tax/accounting, where applicable — Art. 6(1)(c) (legal obligation).

3. Recipients / processors

  • Cloudflare, Inc. — hosting, edge delivery, and KV storage.
  • Email provider (Resend / an SMTP host) — where used, to deliver a license key.

4. International transfers

Some processors are based outside the EU/EEA (e.g. the US). Transfers are safeguarded by adequacy decisions or EU Standard Contractual Clauses.

5. Retention

License records are kept in KV for up to 90 days. Any invoice and tax records are retained for the statutory period.

6. Your rights

You have the right to access, rectification, erasure, restriction, data portability, and to object. You may withdraw consent at any time and lodge a complaint with a supervisory authority (in Germany, the data-protection authority of your state). To exercise your rights, email licensing@davidschneider.xyz.

7. Cookies & tracking

We use no advertising or analytics cookies. The only client-side storage is the localStorage entry described above.

03Refund Policy

30-day money-back guarantee

If you’re not happy with your purchase, contact us within 30 days of the order and we’ll refund it in full — no questions asked. Email licensing@davidschneider.xyz from your order email address (or include your Paddle receipt).

How refunds are processed

Refunds are issued by Paddle, our Merchant of Record, back to your original payment method. Once a purchase is refunded, the associated license is void and must no longer be used.

Business subscriptions

You can cancel an annual Business subscription at any time to stop future renewals. The 30-day guarantee applies to the initial purchase of each term.

Statutory rights

For consumers in the EU, your statutory 14-day right of withdrawal for digital purchases remains unaffected and is honored in addition to this guarantee.
