The short version
By using OPS you get a 14-day free trial. After that you're billed monthly or annually. You can cancel anytime and keep access until your paid period ends. Within 30 days of your first payment, you can email us for a full refund — no questions. Don't share your account, don't try to reverse-engineer the model, and remember OPS is a forecasting tool, not financial advice.
The long version is below.
1. Who we are & agreeing to these terms
One Proven System ("OPS," "we," "us," "our") is operated by Kaden Hesse, a sole proprietor based in the State of Tennessee, United States.
These Terms & Conditions ("Terms") govern your access to and use of the OPS website (oneprovensystem.com), the OPS Chrome extension ("One Proven System Adaptive Indicator"), and the OPS API (collectively, the "Service").
By creating an account, installing the extension, or otherwise using the Service, you agree to be bound by these Terms, our Privacy Policy, and our Risk Disclaimer. If you don't agree, don't use the Service.
2. Eligibility
You must be at least 18 years old and have the legal capacity to enter contracts in your jurisdiction to use OPS. By signing up you represent that you meet this requirement.
If we discover you are under 18, we may terminate your account and refund any unused paid time.
3. Your account
- You are responsible for keeping your password and credentials secure.
- Everything that happens under your account is your responsibility, whether or not you authorized it.
- If you suspect unauthorized use of your account, change your password immediately and email kaden@oneprovensystem.com.
- One account per person. You may not share your login credentials with anyone else, or let multiple people use the same account.
- The information you provide at signup must be accurate. Keep it up to date.
4. Subscriptions, trials & billing
Free trial
New customers get a 14-day free trial. You enter your payment details at signup but are not charged during the trial. At the end of the 14 days, your subscription automatically converts to a paid plan and your card is charged for the plan you selected (monthly or annual). You can cancel at any time during the trial to avoid being charged.
Note: if you change your plan during the free trial (e.g., switch from monthly to annual), the trial ends immediately and your card is charged for the new plan at that time.
Recurring billing
Subscriptions renew automatically at the end of each billing cycle (monthly or annually) until you cancel. Your card on file will be charged at the start of each new period. Pricing is shown at signup and may change — see Section 5.
Cancellation
You may cancel at any time from your account billing portal. Cancellation takes effect at the end of your current billing period: you keep access until then, and you are not charged again. We do not pro-rate or refund unused time on a normal cancellation (but see "Refund policy" below).
Refund policy — 30-day money-back guarantee
Within 30 days of your first payment (i.e., 30 days from the end of your free trial), if OPS isn't adding value to your trading, email kaden@oneprovensystem.com and we will refund every dollar you've paid us, no questions asked.
The guarantee window starts when you make your first payment and runs for 30 calendar days. After that window, payments are non-refundable, except as required by law or at our sole discretion.
Plan changes
You can switch between monthly and annual plans at any time from your account billing portal. Plan changes take effect immediately and are prorated:
- Upgrades (e.g., monthly to annual): the unused portion of your current plan is credited toward the new plan, and your card is charged for the difference at the time of the switch.
- Downgrades (e.g., annual to monthly): the unused portion of your current plan is added to your account as a credit balance, which is automatically applied to future invoices until it's used up. We do not refund downgrade credits to your card by default, but if you'd prefer a cash refund of unused time, email kaden@oneprovensystem.com and we'll consider it on a case-by-case basis.
Failed payments
If your card is declined, your subscription will be marked past-due and we may suspend access until payment succeeds. We use Stripe's standard retry logic. If we can't collect payment after several attempts, the subscription will be canceled.
Taxes
Subscription prices are shown exclusive of any sales tax, VAT, GST, or similar charges that may apply based on your location. Where applicable, those will be added at checkout.
5. Price changes & service changes
We reserve the right to change subscription pricing, modify features, or discontinue parts of the Service at any time. For paying subscribers, price increases take effect at your next renewal, and you can cancel before the new rate is charged if you don't want to continue.
We may add, remove, or change features in the Service without prior notice. We will typically announce significant changes, but we are not obligated to.
6. License to use OPS
Subject to these Terms and your payment of any applicable fees, we grant you a limited, personal, non-exclusive, non-transferable, revocable license to access and use the Service for your individual trading and research.
You may not:
- Reverse-engineer, decompile, disassemble, or otherwise attempt to derive the source code of the OPS extension, the underlying forecasting model, or any other part of the Service.
- Attempt to extract or reconstruct the model from its outputs, including by systematic probing of the API.
- Share, sell, sublicense, lease, or transfer your account credentials or your access to the Service to any other person.
- Use the Service in any way that violates applicable law or infringes the rights of others.
Within those limits, what you do with the forecasts is up to you. Use them for your own trades, paper trade against them, build your own analysis around them — that's why you're paying us.
7. Intellectual property
OPS, the "One Proven System" name and logo, the OPS Chrome extension, the forecasting model (including its architecture and trained weights), the website, and all associated content (text, graphics, code, design, and model outputs) are owned by Kaden Hesse and protected by U.S. copyright, trade secret, and common-law trademark rights.
The historical market data used to train the model is licensed from third-party data providers, who retain ownership of that data. OPS uses it under the terms of those licenses.
Nothing in these Terms transfers any ownership of OPS or its underlying intellectual property to you. You receive only the limited license described in Section 6.
You may not use the OPS name, logo, or branding to imply endorsement or affiliation without our written permission.
8. Model availability
Out of fairness to all our subscribers, we sell access to the OPS forecasting model through subscriptions and do not provide it as a standalone product.
If you represent an institutional buyer interested in acquiring the model outright, the price is $5,000,000 USD. Inquiries: kaden@oneprovensystem.com. We reserve the right to accept or decline any such offer at our discretion.
9. Community spaces
Some plans include access to community spaces (such as our Discord server). Conduct in those spaces is governed by their own community guidelines in addition to these Terms. We may remove you from community spaces — or your account entirely — for violating those guidelines.
10. Risk & not investment advice
OPS is a forecasting tool for informational and educational purposes only. It is not investment advice, and we are not registered as a broker-dealer or investment adviser. All trading involves risk, including loss of principal.
Your use of OPS forecasts is subject to our Risk Disclaimer, which is incorporated into these Terms by reference. Please read it.
11. Disclaimer of warranties
THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED. TO THE FULLEST EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, AND UNINTERRUPTED OR ERROR-FREE OPERATION.
WE DO NOT WARRANT THAT THE FORECASTS WILL BE ACCURATE, THAT THE SERVICE WILL ALWAYS BE AVAILABLE, OR THAT YOUR USE OF OPS WILL BE PROFITABLE.
12. Limitation of liability
TO THE FULLEST EXTENT PERMITTED BY LAW, KADEN HESSE (DOING BUSINESS AS ONE PROVEN SYSTEM) WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, OR TRADING LOSSES, ARISING OUT OF OR RELATING TO YOUR USE OF THE SERVICE, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
OUR TOTAL LIABILITY TO YOU FOR ANY CLAIM ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS IS LIMITED TO THE GREATER OF (A) THE AMOUNT YOU PAID US IN THE 12 MONTHS BEFORE THE CLAIM AROSE, OR (B) $100 USD.
Some jurisdictions don't allow these limitations, in which case they apply to you only to the extent permitted by law.
13. Indemnification
You agree to indemnify, defend, and hold harmless Kaden Hesse and any affiliates from any claims, damages, losses, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or relating to (a) your use or misuse of the Service, (b) your breach of these Terms, (c) your violation of any law or third-party right, or (d) any trades or financial decisions you make based on OPS forecasts.
14. Termination
You may stop using OPS at any time by canceling your subscription and/or deleting your account.
We may suspend or terminate your account at any time if you violate these Terms, attempt to reverse-engineer or extract the model, share credentials, abuse our refund policy, initiate a chargeback in bad faith, or otherwise misuse the Service. We may also terminate the Service entirely or for any specific user at our discretion.
If we terminate your account for a violation of these Terms, you forfeit any unused paid time and are not entitled to a refund. If we terminate your account without cause, we will refund the unused portion of your current billing period.
Sections of these Terms that by their nature should survive termination (including Sections 7, 10, 11, 12, 13, 15, and 16) will survive.
15. Governing law & dispute resolution
These Terms and any dispute arising under them are governed by the laws of the State of Tennessee, United States, without regard to its conflict-of-laws principles.
Try to resolve it informally first
Before either party files a lawsuit, the party with the complaint must give the other party written notice describing the dispute and what they want, and both parties must try in good faith to resolve it informally for at least 60 days after the notice is received. Most disputes get resolved by a couple of emails — if yours is one of them, this saves us both time and money.
Send written notice to us at kaden@oneprovensystem.com. We'll send notice to you at the email on your account.
Optional mediation
If the dispute isn't resolved during the 60-day informal period, either party may propose non-binding mediation through a mutually agreed neutral mediator before filing a lawsuit. Neither party is required to mediate, but if both agree, mediation costs are split equally.
Courts & venue
If the dispute remains unresolved, any legal action arising out of or relating to these Terms or the Service must be brought exclusively in the state or federal courts located in Tennessee. You consent to personal jurisdiction in those courts and waive any objection based on forum or venue.
Prevailing party recovers fees
In any dispute, lawsuit, or proceeding arising out of or relating to these Terms or the Service, the prevailing party is entitled to recover its reasonable attorneys' fees and costs from the non-prevailing party, in addition to any other relief awarded.
16. Miscellaneous
- Entire agreement. These Terms, together with the Privacy Policy and Risk Disclaimer, are the entire agreement between you and us regarding the Service.
- Severability. If any provision of these Terms is found to be unenforceable, the rest will remain in effect.
- No waiver. Our failure to enforce any provision is not a waiver of our right to enforce it later.
- Assignment. You may not assign or transfer these Terms or your account without our written consent. We may assign these Terms in connection with a sale, merger, or other business transaction.
- No partnership. Nothing in these Terms creates a partnership, agency, joint venture, or employment relationship between you and us.
- Notices. We may give you notice by email to the address on your account. You can give us notice by email to kaden@oneprovensystem.com.
17. Changes to these Terms
We may update these Terms from time to time. The most current version will always be at oneprovensystem.com/terms, with the "Last Updated" date at the top reflecting the most recent change.
For material changes that affect your rights, we'll notify active users by email before the changes take effect. Continued use of the Service after a change means you accept the updated Terms.
