Terms of Service
1. What Sifaka is
Sifaka is an AI-driven research and analysis service for prediction markets — currently focused on Polymarket. We publish trading signals (entry direction, target, stop) generated by our automated pipeline to subscribers across three tiers (Free, Pro, Max).
Signals are research output, not investment advice. We are not a registered investment adviser, broker, or fund manager. You are solely responsible for your own trading decisions and any positions you take based on our content. See the Risk Disclaimer for the full disclosure.
2. Account & eligibility
You must be at least 18 years old to subscribe. By creating an account you confirm you have the legal capacity to enter into this agreement in your jurisdiction.
Geographic restrictions [LEGAL]: Polymarket itself restricts access from certain jurisdictions (including, at the time of writing, the United States). Sifaka does not transact with Polymarket on your behalf — but if your jurisdiction prohibits you from accessing Polymarket, our signals will be of no operational use to you. You are responsible for confirming that subscribing to Sifaka and acting on prediction-market research is lawful where you reside.
3. Subscription, billing & cancellation
Tiers and pricing appear on the pricing page. Pricing is denominated in USD, billed in USD via Stripe or in USDC/USDT via supported chains.
Billing cycle: Stripe subscriptions auto-renew at the
end of each billing period unless cancelled. Crypto-paid subscriptions
are one-time and do not auto-renew; they expire at current_period_end
unless you initiate a new payment.
Cancellation: You may cancel renewal at any time from
your account page.
Cancelling sets auto_renew=0; you retain full tier access
through the end of your current billing period, then drop to free tier.
Refund policy: All sales are final by default.
Refunds are issued only on case-by-case manual review where Sifaka
believes the product materially failed (e.g. extended outage that
prevented you from receiving signals you paid for). Email
support@chronax.ai with your subscription ID and
circumstances; decisions are at our sole discretion.
Chargebacks: Initiating a chargeback or payment dispute without first contacting support violates these terms. We reserve the right to terminate access pending dispute resolution.
4. Permitted use
You agree NOT to:
- Resell, republish, or systematically redistribute our signals to third parties without written permission. (Personal use across your own devices is fine.)
- Reverse-engineer, scrape, or otherwise extract our model outputs at scale for the purpose of cloning the service.
- Share account credentials. Each subscription is licensed to one person; we may detect concurrent multi-device use and suspend.
- Use Sifaka content in ways that violate Polymarket's Terms of Use or applicable law.
5. AI-generated content [LEGAL]
Sifaka's signals are produced by an automated pipeline that combines large language model inference, market-data analysis, and rule-based gates. Outputs may contain errors. We do not guarantee:
- Accuracy of any individual signal's prediction.
- Profitability of acting on any signal or sequence of signals.
- Continuous availability — service may be interrupted for maintenance, model updates, infrastructure outages, or upstream (Polymarket / RPC / news source) failures.
Historical performance shown on the public track record is not indicative of future results. Backtests, signal call P&L, and signed monthly attestations all carry the methodology disclaimers published alongside them.
6. Privacy preserves Sifaka's trading wallet
Sifaka operates its own trading capital. The wallets we use to trade are intentionally kept private so that our edge is not free-ridden by on-chain copy-traders — which would harm both Sifaka and our subscribers (whose entry/exit prices would worsen as our public wallet gets front-run). To compensate for the resulting opacity, we publish:
- SHA-256 commitments of every signal at push time, anchored to Polygon mainnet (verifiable on-chain).
- 30-day delayed plaintext of those signals, plus IPFS bundles, for independent verification.
- Monthly fund-P&L attestations signed by our public operator EOA.
See the Risk Disclaimer for the full trust model and its limitations.
7. Intellectual property
Sifaka content (signals, written commentary, dashboards, trained models) is the property of Sifaka / Chronax. Subscribers receive a non-exclusive, non-transferable license to use the content for personal trading research during their subscription period. The license terminates when the subscription does.
8. Termination
You may terminate at any time by cancelling your subscription. We may terminate or suspend your account immediately if you breach these terms, abuse the service, or initiate a payment dispute without first contacting support. Upon termination of either party, sections regarding intellectual property, disclaimers, limitation of liability, and governing law survive.
9. Limitation of liability [LEGAL]
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, SIFAKA AND CHRONAX SHALL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING LOST PROFITS, ARISING OUT OF OR RELATING TO YOUR USE OF THE SERVICE — REGARDLESS OF WHETHER THE CLAIM IS BASED ON CONTRACT, TORT, OR ANY OTHER LEGAL THEORY, AND EVEN IF SIFAKA HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
Our aggregate liability for any claim shall not exceed the greater of (a) the amount you paid Sifaka in the 12 months preceding the claim, or (b) USD 100.
10. Changes to these terms
We may update these terms from time to time. Material changes will be announced via the email on file at least 14 days before they take effect. Continued use of the service after the effective date constitutes acceptance.
11. Governing law & disputes [LEGAL]
These terms are governed by the laws of [JURISDICTION TBD — lawyer to insert]. Any dispute arising from your use of the service shall be resolved in the courts of [VENUE TBD].
