TERMS OF SERVICE
The rules of using Sonar.
1. Educational software
Sonar provides charts, pattern analysis, probability estimates, market commentary, and educational material. It does not execute trades, hold customer funds, act as a broker, guarantee results, or provide individualized financial, legal, or tax advice.
2. Eligibility and account use
You must be legally able to enter this agreement and use Sonar only where lawful. You are responsible for following the terms of every exchange, prediction market, data provider, or other service you use. Access is personal, limited to one active session, and may not be resold, credential-shared, streamed, scraped, or used to operate a competing product. Starting a new session automatically ends the previous one. Sonar records limited account, sign-in, device, network, and protected-access activity for security, fraud prevention, enforcing these terms, and payment-dispute defense as described in the Privacy Policy.
3. Plans, taxes, cancellation, lifetime access, and refunds
Sonar Pro is available through a $105 USD monthly subscription, a $1,550 USD one-time lifetime-access purchase, and, only while the limited offer is open, a $39 USD weekly subscription. Applicable taxes are calculated at checkout. Weekly and monthly subscriptions renew automatically through Stripe until canceled. Cancellation stops future renewals, and access normally continues through the paid period.
The weekly plan is a one-time signup opportunity per customer and email. Once a weekly subscription ends after cancellation, the customer permanently loses eligibility to restart or repurchase the weekly plan. Monthly and lifetime options remain available. Eligible weekly members may receive a one-time, non-transferable $20 credit toward their first monthly subscription payment. The credit has no cash value, cannot be combined with other discounts, and is considered used when the discounted monthly checkout completes. Starting that monthly plan ends the prior weekly subscription.
“Lifetime” means access for the operational lifetime of the Sonar product and service, not the purchaser's natural lifetime. It does not guarantee that the product, specific features, market-data sources, or third-party integrations will remain available forever.
Except where required by applicable law, all weekly and monthly charges, renewals, lifetime purchases, discounted purchases, and other access fees are final and non-refundable after access is provisioned. Canceling a subscription prevents future renewals but does not refund the current paid period. Sonar may approve a full or partial refund in its sole discretion. A discretionary exception for one customer does not create a continuing refund policy or obligation for other purchases. Contact support promptly if a charge was unauthorized, duplicated, or access was not delivered.
4. Market and data risk
Markets are volatile and contracts can lose their full purchase price. Data, calculations, signals, and availability may be delayed, incomplete, interrupted, or incorrect. You are solely responsible for deciding whether and how to trade.
5. Acceptable use
Do not bypass access controls, share credentials, scrape or redistribute protected output, interfere with the service, reverse engineer restricted components, or use Sonar for unlawful activity. We may suspend access for abuse, fraud, chargebacks, or a canceled or unpaid subscription.
6. Intellectual property
Sonar’s interface, lessons, annotations, scoring logic, copy, and original materials remain the property of Sonar and its licensors. Your subscription grants a limited, revocable, non-transferable right to use the service personally.
7. Service changes and liability
Features may change as Sonar develops. To the maximum extent permitted by law, Sonar is provided “as is” without warranties, and Sonar is not liable for trading losses, lost profits, data interruptions, or indirect damages arising from use of the service.
8. Account recovery
Account recovery uses email-bound, one-time links supplied by Sonar support. You are responsible for protecting your email account, password, and reset links. Sonar support will never request your password, Kalshi private key, or full payment-card number.
9. Contact and updates
Material terms changes will be posted here with a new effective date. Contact the business through the support channel shown on your Stripe receipt or the Sonar support guide.
