These terms and conditions govern the rights and obligations between the Operator of the service DJanalyzer and the user. The Operator is Ondřej Bachurek, IČO 87344149 (hereinafter the “Operator”).

1. Subject of the service, nature of the app and independence

DJanalyzer is an independent web application (digital content / SaaS available at https://open.djanalyzer.com) for the analysis and management of the user’s own music library created with the Engine DJ software. The app works exclusively with standard database files (SQLite) that the user uploads themselves, and processes them locally in the user’s browser; the content of the library is not sent to the Operator’s servers.

It is a tool for interoperability with the user’s own data. The app does not contain, distribute or modify any program code, libraries or other protected third-party content, and does not circumvent any technical protection measures.

DJanalyzer is not created by inMusic Brands, Inc. or Denon DJ, is in no way affiliated with them, and is not authorised or endorsed by them. “Engine DJ” and “Denon DJ” are trade marks of inMusic Brands, Inc.; the Operator uses them solely to truthfully indicate compatibility (nominative use) and makes no claim to them. The Operator does not warrant compatibility with future versions of Engine DJ; the manufacturer may change the database format at any time, which may limit or interrupt the app’s functionality without this constituting a defect in the Operator’s performance.

2. Plans and licences

Free - a free-of-charge plan with no time limit.
Pro / Studio - a paid subscription (monthly or annual), or optionally a lifetime licence as a surcharge.

After payment, a unique licence key is generated for the user, which activates the relevant features in the app. The key is tied to the user’s account and may not be shared beyond the purchased number of devices.

3. Price and payment

Prices are stated in EUR (indicatively also in CZK) and are final. Payment is made through the secure Stripe payment gateway. The subscription automatically renews at the end of the period until the user cancels it.

4. Subscription, its renewal and cancellation

The paid plans (Pro / Studio) are arranged as a recurring subscription with a monthly or annual billing period. At the end of each period the subscription renews automatically and the payment method stored with the Stripe payment gateway is charged the price for the next period, until the user cancels the subscription. Any lifetime licence does not renew and is not subject to this provision.

The user may cancel the subscription at any time, namely in their account at djanalyzer.com (the subscription section, the “Cancel subscription” button), or by sending a request to podpora@djanalyzer.com.

The cancellation takes effect at the end of the current paid period: the period already running runs out in full and no further payment is charged. The cancellation therefore does not terminate the subscription immediately and does not give rise to a right to a refund of the price for the period already started (see also Article 5). After the paid period ends, the account automatically switches to the free Free plan; the user retains access to the app, only without the paid features.

Until the current period ends, the cancellation can be reversed using the “Renew subscription” button in the account — the subscription will then continue to renew automatically. The user is informed of the cancellation and its effects by a confirmation e-mail.

5. Withdrawal from the contract and digital content

DJanalyzer is a digital service that is activated immediately upon payment by generating a unique licence key. Trying the product before purchase is possible in the fully featured free Free plan - without a payment card and with no time limit.

Under Section 1829 of the Czech Civil Code, a consumer has the right to withdraw from a contract concluded by distance means within 14 days. In the case of digital content not supplied on a tangible medium and services whose performance has begun with the consumer’s prior express consent before the expiry of this period, this right ceases to exist under Section 1837(l) of the Czech Civil Code.

When completing the order at the checkout, the consumer expressly consents to the commencement of the provision of the digital service (generation and activation of the licence key) before the expiry of the 14-day withdrawal period and acknowledges that by doing so they lose the right to withdraw from the contract under Section 1837(l) of the Czech Civil Code.

The Operator does not offer a voluntary “money-back guarantee”. This does not affect the Operator’s liability for defects in performance under Section 2099 et seq. of the Czech Civil Code - the procedure and conditions for complaints are described in the Complaints Procedure.

6. Privacy and data

The app processes the user’s music database exclusively locally in the browser; the content of the library is not sent to the Operator’s servers. The processing of the account’s personal data is governed by the Personal Data Protection.

7. The user’s obligations, warranties and limitation of liability

The user undertakes and declares that they:

process exclusively their own music library, to which they have the necessary rights, and do not use the app to infringe the rights of third parties or in breach of the licence terms of the software whose data they process;
create and maintain a backup of both the database and the music files before each modification;
will not run the app at the same time as the Engine DJ software over the same library — concurrent access may corrupt the data;
will not use the app to circumvent technical protection measures or for any other unlawful conduct.

The service is provided “as is” and “as available”. To the extent permitted by law, the Operator does not provide any express or implied warranties beyond those that cannot be validly excluded against a consumer — in particular it does not warrant uninterrupted or error-free operation or lasting compatibility with the Engine DJ software.

Working with the database is a risky operation. To the extent permitted by law, the Operator is not liable for the loss, damage or corruption of data (in particular the Engine DJ library or music files) arising from use of the app, a change of format by the Engine DJ manufacturer, concurrent access or an inadequate backup; the user alone is responsible for maintaining backups.

To the extent permitted by law, the Operator is not liable for indirect, consequential or special damage (in particular lost profit, loss of data or business interruption), and its total aggregate liability arising in connection with the service is limited to the amount of the price the user paid for the service over the last 12 months.

This does not affect the consumer’s rights that under mandatory legal regulations cannot be excluded or limited, nor the Operator’s liability for damage caused intentionally or through gross negligence or to a person’s natural rights. Liability for defects in performance is governed by the Complaints Procedure.

All rights to the DJanalyzer app (program code, design and name) belong to the Operator; the user is granted a non-exclusive and non-transferable right to use the app to the extent of the purchased plan. The user’s data remains their property.

8. Final provisions

These relations are governed by the law of the Czech Republic. The Operator may amend these terms; the current wording is always on this page. Please direct any questions to podpora@djanalyzer.com.
