This policy explains what Sonar Sciences refunds, what it does not, and how to ask. It sits alongside the Terms of Service and does not replace them. In one paragraph: unspent execution wallet balance is yours and comes back on request; a subscription is refundable in full within 14 days if you have not used the paid tier, and pro-rata by whole unused months on an annual plan within 30 days; billing errors are always corrected in full; trading losses are not a Sonar charge and cannot be refunded by us, because your trades happen on your own broker account and Sonar never holds the money.
Sonar Sciences is a product of Friddy, Inc., a Delaware corporation with its registered office at 8 The Green, Suite A, Dover, DE 19901, USA. Refund requests go to support@sonar-sci.com, and every request is answered by a person.
This policy was last updated on 3 August 2026 and applies to payments made on or after that date. If we change it, the version in force when you paid is the one that governs your payment.
Refund treatment differs for each, because what happens to the money differs. Knowing which one you paid for is the first step in any request.
| What | What it buys | How it is treated |
|---|---|---|
| A model access subscription | Free, Basic at $29 per month or $290 per year, Pro at $49 per month or $490 per year, Premium at $149 per month or $1,490 per year. | Earned when you pay. Refundable under sections 4 and 5. |
| An execution wallet prefund | Credit held against future execution fees on your own winning trades. | Not revenue. It is credit you have not spent, and the ledger records it as money we still owe you in service. Refundable under section 6. |
| An execution fee already charged | The platform share taken from your prefund when one of your own trades closes in profit. | Earned at the moment it is charged. Refundable only if it was charged in error, under section 8. |
The Studio, the module library, backtesting and forward testing cost nothing and never have. If you have not paid for one of the three things above, there is nothing to refund and nothing to cancel.
Sonar Sciences takes payment in stablecoin only: USDC or USDT on Base, BNB Chain, Solana or Tron. There is no card processor, no PayPal, and no bank transfer.
Three consequences follow, and they are the reason this policy is written the way it is.
If you have not used the paid tier, you get all of it back, no questions. Ask within 14 days of the payment and we refund the full amount.
"Used the paid tier" means you opened, viewed or ran a model that your subscription unlocked and the free tier does not. Signing in, building your own strategies, backtesting them and forward testing them are all free at every tier, so none of them count as use, and none of them cost you the refund.
If you have used the paid tier inside those 14 days, we refund the unused part on a daily pro-rata basis and keep the days you used. We will tell you the arithmetic rather than announce a number.
You have a statutory right to withdraw from a distance contract for digital services within 14 days. Where you ask us to begin supplying the service immediately, which is what subscribing does, that right can be lost once supply has begun, and you acknowledge that when you subscribe. We do not rely on that. The 14 day term above is offered voluntarily and is at least as good as the statutory minimum. Nothing in this policy reduces a right you have by law.
Annual plans. Within 30 days of an annual payment, we refund every whole month you have not yet entered, less the months already begun charged at the monthly rate for your tier. After 30 days an annual plan is not refundable except under sections 8 and 9. An annual plan already carries two months free, which is why the window is wider and then closes.
Cancelling. Cancelling stops the subscription from continuing. It does not take away the time you have already paid for: your tier stays active until the end of the period you bought, and then it ends. Because every period is paid by hand in stablecoin, there is nothing that automatically renews and nothing that can charge you again without you sending another payment.
Price changes. If we lower a price, the new price applies to your next payment. If we raise one, it applies only to payments you make after we tell you. We do not change the price of a period you have already paid for.
If we end the service. If Sonar Sciences discontinues a paid tier, or terminates your access for a reason that is not a breach by you, we refund the unused part of any period you have paid for, pro-rata by day.
A prefund is not a purchase. It is credit you have placed with us against fees that have not been charged yet, and our own accounting records it as an obligation rather than as income until a fee draws on it.
You can ask for your unspent balance back at any time, for any reason, with no time limit. There is no fee for doing so, and doing so does not close your account.
Two practical limits, neither of them discretionary:
If you overpay, the surplus is credited to your account balance automatically, on the same day, and shown on your balances page. It is not lost and it does not need a request. If you would rather have it back on-chain than hold it as credit, ask, and section 6 applies to it.
If you underpay, the order stays open for 24 hours so you can send the difference, and it activates as soon as the total reaches the amount owed. If you do not top it up, ask us and we return what you did send, less the network fee. We do not keep partial payments for orders that never completed.
If you pay after the quote expires, or on a different network to the one the order names, tell us with the transaction hash. Funds sent to an address we generated are recoverable and we will either apply them to the order or return them. Funds sent to an address we did not generate are not recoverable by us or by anyone.
If we charged you something you did not owe, we refund it in full, regardless of any window in this policy, and we do not require you to have noticed within any period. This covers a duplicate payment applied twice, a fee charged on a trade that did not close in profit, a fee charged at the wrong rate, and a subscription charged for a tier you did not buy.
Every fee is written to a double-entry ledger at the moment it is charged, and every entry names the trade it came from. If you think a fee is wrong, send us the date and we will show you the entry and the trade behind it. If it is wrong, we correct it and we tell you what happened.
Email support@sonar-sci.com from the address on your account, or open a support ticket from inside the console. Include:
We acknowledge every request within one business day and tell you the decision within five. If we owe you money, we send it within five business days of that decision, on the same network and in the same token you paid with unless you ask otherwise.
We send refunds to the address you paid from by default, because that address is the only thing tying the payment to you. If you ask us to send to a different address we may ask you to prove you control it, and for larger amounts we may need to verify your identity before we can pay out, which is a legal obligation rather than a preference.
Because there is no card network in the middle, there is no chargeback to file and no intermediary to escalate to. If you disagree with a decision, reply and say so, and a second person who was not involved in the first answer will look at it. If we still disagree, section 16 of the Terms of Service governs how the dispute is resolved, and your statutory rights are unaffected by anything in this policy.
We cannot send funds to an address or a person subject to sanctions, or where doing so would breach applicable law. If that applies, we will tell you that it applies, in those terms, rather than leaving a request unanswered.
