1. Overview
This Refund & Cancellation Policy forms part of the ZephirexULTRA Terms of Service and applies to all paid subscriptions purchased from Zephirex Technologies LLC ("Zephirex", "we", "us"). All payments are processed securely by our payment processor, Stripe.
We want you to subscribe with confidence. You can explore the platform first with our free Nebula plan or the public demo before paying for anything, and every first-time paid subscription is covered by the money-back guarantee described below.
2. Cancelling Your Subscription
You can cancel at any time, without a fee and without contacting us. Go to the Pricing page while signed in and choose Manage billing, or email [email protected] from the address on your account.
Cancellation takes effect at the end of your current billing period. You keep full access to your paid plan until then, and you will not be charged again. When the period ends, your account automatically moves to the free Nebula plan. Your account, journal entries, alerts, and settings are kept; exchange API keys beyond the Nebula plan limit are locked (not deleted) until you upgrade again.
Cancelling stops future charges only. It does not by itself trigger a refund for the current period; refunds are handled under the sections below.
3. First-Time Money-Back Guarantee
Monthly plans: If this is your first paid subscription with us, you may request a full refund of your first monthly payment within 7 days of the charge.
Annual plans: If this is your first paid subscription with us, you may request a full refund of your first annual payment within 14 days of the charge.
The guarantee applies once per person and per payment method. When a guarantee refund is issued, the subscription is cancelled immediately and the account moves to the free Nebula plan.
4. Renewals
Monthly renewals: Monthly renewal charges are non-refundable. Cancel before your renewal date to avoid the next charge.
Annual renewals: If an annual plan renews and you no longer want it, contact us within 7 days of the renewal charge and we will refund that renewal in full and cancel the subscription.
After the windows above have passed, payments are non-refundable and we do not issue partial or prorated refunds for unused time. You can still cancel at any time to stop future renewals.
5. Upgrades, Downgrades and Plan Changes
Upgrades take effect immediately. You are charged a prorated amount for the remainder of your current billing period, calculated automatically by Stripe.
Downgrades and billing-interval changes also take effect immediately. Any unused value from your previous plan is applied as a prorated credit toward your future invoices. Credits are not paid out as cash refunds.
Proration charges from an upgrade are covered by the guarantee in Section 3 only if they fall within the original guarantee window of your first paid subscription.
6. Billing Errors and Service Outages
Duplicate or incorrect charges: If you were charged twice, charged the wrong amount, or charged after a cancellation took effect, we will refund the error in full. Please report it within 60 days of the charge.
Extended outages: If the Service is unavailable for more than 72 consecutive hours because of a failure in our own systems, you may request a service credit proportional to the downtime, applied to your next invoice. Outages caused by connected exchanges, their APIs, or other third parties are outside our control and are not eligible.
7. What Is Not Refundable
Refunds are not provided for: (a) trading losses, missed opportunities, or market performance of any kind; (b) unused time on a plan after the refund windows above; (c) periods in which you did not use the Service; (d) exchange downtime, API changes, or other third-party issues; (e) accounts suspended or terminated for violating our Terms of Service; or (f) live data paused because two-factor authentication was not enabled after the 45-day buffer for accounts with API keys.
We may decline refund requests that show a pattern of abuse, such as repeatedly subscribing and requesting refunds.
8. How to Request a Refund
Email [email protected] from the email address on your account. Include the date and amount of the charge and a short reason for the request. We reply within 3 business days.
Approved refunds are issued through Stripe to the original payment method. Card refunds usually appear within 5–10 business days, depending on your bank. Payments made with stablecoins are refunded in the U.S. dollar amount originally charged, using the refund method Stripe supports for that payment; we do not adjust refunds for changes in the market value of digital assets.
When a full refund is issued for a billing period, paid access for that period ends immediately and the account moves to the free Nebula plan.
9. Chargebacks and Disputes
If something is wrong with a charge, please contact us first — we can usually resolve it faster than a bank dispute. If a chargeback is filed, we may suspend paid access to the account while the dispute is reviewed. Chargebacks found to be fraudulent may result in account termination.
10. Price Changes
If we change the price of your plan, we will notify you at least 14 days before the new price applies to your next renewal. If you do not agree with the change, you can cancel before the renewal date and you will not be charged the new price.
11. Your Legal Rights
Nothing in this policy limits any rights you may have under the consumer protection laws that apply to you. Where those laws give you a greater right to a refund or cancellation, those laws apply.
12. Changes to This Policy
We may update this policy from time to time. Changes apply to payments made after the updated policy is posted; the policy in effect at the time of your payment governs any refund for that payment. The "Last updated" date reflects the most recent revision.
