  • Email support for installation, configuration, and troubleshooting

4.2 After the Support Period

  • Issues arising from unsupported OJS versions

4.4 Response Time

We aim to respond to support inquiries within 2–3 business days. We do not guarantee 24/7 availability.

5. Data Collection and Privacy

5.1 Plugin Telemetry

Our Plugins may send a one-time, non-blocking request to our server upon activation. This request contains:

  • The URL of the journal where the Plugin is installed
  • Plugin name and version
  • OJS version number

This data is used solely for:

  • Verifying authorized installations
  • Providing compatibility notifications
  • Improving our products

5.2 No Personal Data

The telemetry request does not contain personal data, user credentials, submission content, reviewer information, or any data entered by journal users.

5.3 Failure Tolerance

If the telemetry request fails (e.g., due to firewall restrictions or lack of internet), the Plugin will continue to function normally. The request is non-blocking and does not affect Plugin operation.

5.4 Payment Data

All payment and personal data related to purchases is processed by Paddle in accordance with their Privacy Policy (https://www.paddle.com/legal/privacy). We do not store credit card numbers or payment credentials.

6. Intellectual Property

All Plugins, including source code, documentation, design, and associated materials, are the intellectual property of OJStack and are protected by applicable copyright laws. Your purchase grants you a usage license as described in Section 3 — it does not transfer ownership of the software.

7. Disclaimer of Warranties

THE PLUGINS ARE PROVIDED “AS IS” AND “AS AVAILABLE”, WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

We do not warrant that:

  • The Plugin will meet all of your requirements
  • The Plugin will be error-free or uninterrupted
  • The Plugin will be compatible with future versions of OJS
  • Defects will be corrected within a specific timeframe

We strongly recommend that you create a full backup of your OJS installation and database before installing or updating any Plugin.

8. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW:

  • Our total liability arising from or related to these Terms or any Plugin shall not exceed the total amount you paid for the specific Plugin giving rise to the claim.
  • We shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to loss of data, loss of revenue, loss of submissions, business interruption, or procurement of substitute services.
  • This limitation applies regardless of the legal theory (contract, tort, negligence, strict liability, or otherwise), even if we have been advised of the possibility of such damages.

9. Refund Policy

9.1 General Rule

Due to the digital nature of our products, all sales are final. Once a Plugin has been delivered (download link provided), we generally do not offer refunds.

9.2 Exceptions

We will provide a full refund within 14 days of purchase if:

  • The Plugin does not function as described on our website, and we are unable to resolve the issue within a reasonable timeframe
  • The Plugin is materially incompatible with a supported OJS version listed on the product page

9.3 Refund Process

To request a refund, contact us at hello@ojstack.dev with your order number and a description of the issue. Refunds are processed through Paddle and typically appear within 5–10 business days.

10. Termination

10.1 By You

You may stop using the Plugin at any time by uninstalling it. No refund is due upon voluntary discontinuation.

10.2 By Us

We reserve the right to revoke your license if you materially breach these Terms, including but not limited to:

  • Redistributing the Plugin to unauthorized parties
  • Using a Single Journal License on multiple journals
  • Circumventing or removing telemetry or license verification mechanisms

Before termination, we will make reasonable efforts to notify you and provide an opportunity to cure the breach within 14 days.

11. Updates to These Terms

We may update these Terms from time to time. Material changes will be communicated via our website. Continued use of the Plugin after changes constitutes acceptance of the updated Terms. We encourage you to review this page periodically.

12. Governing Law

These Terms are governed by the laws of the Republic of Poland. Any disputes arising from these Terms shall be subject to the exclusive jurisdiction of the courts in [Your City], Poland. If you are a consumer within the EU, you retain any mandatory consumer protection rights under the laws of your country of residence.
