Acceptable use

You agree not to:

• Use automated tools, bots, or scripts to scrape or bulk-download signal data from Sonar.

Signal data

• Signals displayed in Sonar are derived from publicly available posts on Reddit and Hacker News. We do not guarantee the accuracy, completeness, or timeliness of this data.
• Signals are provided for informational purposes only. They are not business advice, market research, or investment recommendations. You are solely responsible for any decisions you make based on signal data.
• We do not claim ownership of the original posts. Original content remains the property of its respective authors and is subject to the terms of its source platform.
• Signal scores are algorithmically generated estimates of demand and should not be treated as definitive measures of market viability.

Intellectual property

The Sonar name, logo, interface design, scoring algorithms, and categorization systems are the intellectual property of 0arch. You may not copy, modify, or distribute any part of the Sonar interface or systems without written permission. Data exported via CSV may be used freely for your own purposes but may not be resold as a data product.

Availability and uptime

We strive to keep Sonar available 24/7 but do not guarantee uninterrupted service. We may perform maintenance, updates, or changes that temporarily affect availability. We are not liable for any losses resulting from service downtime or interruptions.

Limitation of liability

To the maximum extent permitted by law, 0arch and its operators shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits or revenues, whether incurred directly or indirectly, or any loss of data, use, goodwill, or other intangible losses resulting from your use of Sonar. Our total liability for any claim arising from these Terms or the service shall not exceed the amount you have paid us in the 12 months preceding the claim.

Disclaimer of warranties

Sonar is provided “as is” and “as available” without warranties of any kind, either express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the service will be error-free, secure, or uninterrupted.

Termination

We may terminate or suspend your account at any time for violation of these Terms, with or without notice. Upon termination, your right to use the service ceases immediately. If we terminate your paid account for reasons other than Terms violations, we will provide a pro-rated refund for the remainder of your billing period.

Governing law

These Terms are governed by the laws of the State of Florida, United States, without regard to conflict of law provisions. Any disputes arising from these Terms or the service shall be resolved in the courts of Miami-Dade County, Florida.

Changes to these terms

We may revise these Terms from time to time. If we make material changes, we will notify you by email or by posting a notice on the site at least 30 days before the changes take effect. Continued use of Sonar after changes become effective constitutes acceptance of the revised Terms.
