1. Agreement to Terms

By accessing or using https://querybolt.io (the "Service"), operated by Vistra Nova Ltd ("we", "us", or "our"), you agree to be bound by these Terms of Service. If you disagree with any part of these terms, you may not access the Service.

2. Description of Service

QueryBolt provides SQL query optimization services, including:

  • Analysis of SQL queries for performance improvements

The Service is provided "as is" and we reserve the right to modify, suspend, or discontinue any aspect of the Service at any time.

  • Provide accurate and complete registration information
  • Maintain the security of your account credentials
  • Notify us immediately of any unauthorized access

3.2 Account Responsibility

You are responsible for all activities that occur under your account. We are not liable for any loss or damage arising from unauthorized use of your account.

  • Other fees are non-refundable except as required by law or expressly stated in these Terms
  • We reserve the right to change pricing with 30 days' notice

4.3 Cancellation

You may cancel your subscription at any time. Cancellation takes effect at the end of your current billing period. No refunds are provided for partial billing periods unless the 14-day money-back guarantee applies or applicable law requires otherwise.

4.4 14-Day Money-Back Guarantee

If you are not satisfied with your first Core or Max subscription purchase, contact support within 14 days of the first payment and we will refund that first subscription payment in full. The guarantee applies once per customer or organization, excludes add-ons, usage-based charges, renewals, and accounts suspended for fraud, abuse, or Terms violations.

5. Acceptable Use

You agree not to:

  • Use the Service for any illegal or unauthorized purpose
  • Upload malicious code, viruses, or harmful content
  • Attempt to gain unauthorized access to the Service or other accounts
  • Interfere with or disrupt the Service or servers
  • Use automated systems to access the Service without permission
  • Reverse engineer, decompile, or disassemble any part of the Service
  • Resell or redistribute the Service without authorization

5.1 Fair Use

Plans described as unlimited are intended for normal interactive team use. We may apply protective rate limits, concurrency limits, queueing, temporary throttling, or account review where usage materially degrades the Service, attempts to bypass quotas, resells capacity, or creates unusual infrastructure cost or security risk.

6. Intellectual Property

The Service, including all content, features, and functionality, is owned by Vistra Nova Ltd and protected by copyright, trademark, and other intellectual property laws.

You retain ownership of any SQL queries you submit. By using the Service, you grant us a license to process and analyze your queries solely for the purpose of providing optimization services.

7. Data and Privacy

Your use of the Service is also governed by our Privacy Policy. We process your data in accordance with UK GDPR and GDPR requirements.

You are responsible for ensuring that any data you submit complies with applicable data protection laws and that you have the necessary rights and permissions.

8. Service Availability

We strive to maintain high availability but do not guarantee uninterrupted or error-free service. The Service may be unavailable due to:

  • Scheduled maintenance
  • Technical issues or failures
  • Force majeure events

We are not liable for any loss or damage resulting from Service unavailability.

9. Limitation of Liability

To the maximum extent permitted by law:

  • The Service is provided "as is" without warranties of any kind
  • We are not liable for any indirect, incidental, or consequential damages
  • Our total liability is limited to the amount you paid in the 12 months preceding the claim
  • We are not responsible for any decisions made based on optimization suggestions

10. Indemnification

You agree to indemnify and hold harmless Vistra Nova Ltd, its officers, directors, employees, and agents from any claims, damages, losses, or expenses arising from:

  • Your use of the Service
  • Your violation of these Terms
  • Your violation of any third-party rights

11. Termination

We may terminate or suspend your account immediately if:

  • You violate these Terms of Service
  • You engage in fraudulent or illegal activity
  • You fail to pay subscription fees
  • We are required to do so by law

Upon termination, your right to use the Service ceases immediately. We may delete your account and data in accordance with our Privacy Policy.

12. Changes to Terms

We reserve the right to modify these Terms at any time. We will notify you of material changes by:

  • Posting the updated Terms on this page
  • Sending an email notification (for significant changes)
  • Updating the "Last updated" date

Your continued use of the Service after changes constitutes acceptance of the new Terms.

12a. Service Communications

While you hold an active subscription, we may contact you by email about the Service itself — including security and availability incidents, planned maintenance, breaking changes, deprecations, and changes to pricing or these Terms. These are part of providing the Service to you and are not marketing.

You may opt out of non-urgent product and service announcements at any time in your account settings. Security and service-critical notices cannot be opted out of while your subscription is active, because they concern the security and availability of your own account.

Marketing email is separate and is only ever sent with your prior consent. See our Privacy Policy for details.

13. Governing Law

These Terms are governed by and construed in accordance with the laws of England and Wales, without regard to conflict of law principles.

Any disputes arising from these Terms shall be subject to the exclusive jurisdiction of the courts of England and Wales.
