Sigma Foundry LLC · Effective date: September 15, 2026 · Updated: November 3, 2026
If a paid app or pass isn't what you expected, email [support@sigmafoundry.io](mailto:support@sigmafoundry.io) from your account email within 14 days of your first payment and we will refund it in full, no questions asked. This applies once per app or pass, to the first charge on a new subscription.
Practice-exam products (CCAR-F Ready Room, CCAR-P Ready Room and the Claude Architect Ready Room Bundle) can be used in full within days, so their money-back window is shorter: email [support@sigmafoundry.io](mailto:support@sigmafoundry.io) from your account email within 7 days of your purchase for a full refund. This replaces the 14-day window above for these products only, and it is stated on each product page and at checkout before you pay.
Renewal charges are generally not refundable. To avoid an unwanted renewal, cancel before your renewal date from your account page — cancellation takes effect immediately for future billing and you keep access to the end of the period you already paid for. If you were charged for a renewal you did not intend and had not used the app that period, contact us within 7 days of the charge; we review these individually and will usually refund or credit the charge.
Open your account page at account.sigmafoundry.io/account, choose Manage billing, and cancel. No phone call, no chat, no retention hoop. You will get a confirmation email from Stripe. We do not issue partial refunds for the unused part of a billing period unless the law where you live requires it.
Approved refunds go back to the original payment method through Stripe, usually within 5–10 business days depending on your bank.
If you have a billing concern, please contact us first — we can almost always resolve it faster than your bank can. Opening a chargeback without contacting us may result in the account being paused while the dispute is reviewed.
We may decline refunds in cases of clear abuse, such as repeated subscribe-refund cycles or violations of our Terms or EULA.
