Refund & Cancellation Policy

Effective 4 November 2026

This policy covers purchases of SuperNotebookLM website and extension plans, operated by Shakthi Sundar. Dodo Payments is the merchant of record for purchases processed through its checkout. Read this policy together with our Terms of Service, the terms displayed at checkout, and Dodo Payments' Buyer Terms. SuperNotebookLM is independent of Google and NotebookLM.

Request a refund or billing review

Email supernotebooklm@gmail.com from the email address associated with your purchase. Include:

• Your account email and order or payment reference from your receipt.
• The purchase date and plan.
• A short description of the problem and whether you also want to cancel future renewal.

Do not send card numbers, passwords, license keys, private research, or authentication tokens. We may ask for information needed to verify ownership and identify the transaction. There is no automatic refund button; sending a request does not itself issue a refund or cancel a subscription.

How requests are reviewed

Contact us promptly about duplicate charges, incorrect billing, or paid access that was not delivered. We review the transaction and access history with Dodo Payments. Depending on the issue, the resolution may be restoring access, correcting billing, or requesting a full or partial refund. Approval depends on the circumstances, the payment provider's applicable terms, and consumer rights; no unconditional money-back guarantee is offered.

Dodo's standard documentation asks customers to request refunds within 7 days of purchase. Please contact us within that period where possible. That provider window does not reduce any mandatory rights you have under applicable law. Requests outside it are reviewed according to those rights and the provider's applicable rules. See Dodo's refund rules.

Cancel a subscription

Sign in and open Billing & account, then choose Manage subscription to open Dodo's customer portal. Follow its cancellation steps and check the confirmation and effective date. If you cannot access the portal, email support with your order reference before renewal; Dodo's Buyer Terms request at least 48 hours' notice for cancellations handled by support.

Cancellation and refunds are separate. Cancellation stops future renewal according to its confirmed effective date; it does not automatically refund an earlier payment. We do not promise prorated refunds for unused subscription time, except where required by law or specifically approved. Paid access follows the confirmed subscription status and effective cancellation date. Uninstalling the extension or deleting local research does not cancel a subscription.

A Lifetime plan is a one-time purchase with no recurring renewal. Refund requests for that purchase use the same review process above.

After a refund is approved

Dodo processes approved refunds to the original payment method. A pending request is not a completed refund; we will confirm the provider's recorded outcome. After a successful refund, funds can take 5–10 business days to appear, depending on the bank and payment method. Refunds and cancellations can change paid feature access; they do not themselves request deletion of your research or account.

Your rights and other charges

Nothing in this policy removes mandatory refund, cancellation, or consumer rights. Charges from separate AI providers or other services you connect are governed by those providers' policies and are not SuperNotebookLM purchases. For privacy or account-deletion requests, see our Privacy Policy.
