Refund Policy

We want you to be satisfied with Mnemosyne. This policy explains when refunds are available and how to request one. It applies to subscriptions to the Mnemosyne Service operated by YHLab.

1. 14-day refund window (web purchases)

If you purchased a subscription on the web through our Merchant of Record, Paddle, you may request a full refund within 14 days of your initial purchase, for any reason. This window applies to first-time purchases of a given plan.

Renewals are eligible for a refund within 7 days of the renewal charge if the subscription has not been actively used during the new billing period (no review sessions, no AI generations, no card edits).

2. When refunds are typically granted

• You were charged twice or charged in error;
• You requested a refund within the eligibility window described above;
• A material technical defect prevented you from using paid features and we were unable to resolve it within a reasonable time;
• An unauthorized charge was made on your account.

3. When refunds are typically not granted

• The refund request is made after the eligibility window has passed;
• The subscription has been substantially used during the billing period for which the refund is requested;
• The account was terminated for a material breach of our Terms of Service;
• Partial refunds for unused time on a canceled subscription — when you cancel, you keep access until the end of the billing period already paid for, but the remaining time is not refunded as cash.

4. How to request a refund (web)

To request a refund for a web subscription:

1. Locate your Paddle receipt email (subject line typically begins with "Your receipt from Paddle on behalf of Mnemosyne").
2. Either reply to that receipt, or contact us directly at yhlab.team@gmail.com with the email address used for purchase and the order ID.
3. We aim to respond within 3 business days. Approved refunds are issued by Paddle to the original payment method, typically within 5–10 business days depending on your bank.

5. Mobile purchases (App Store / Google Play)

Subscriptions purchased through the Apple App Store or Google Play are sold and refunded by the respective store, not by us. We do not have the ability to issue refunds for mobile purchases directly. Please use:

• Apple App Store — reportaproblem.apple.com
• Google Play — Google Play refund request

We are happy to support you with documentation if needed — contact yhlab.team@gmail.com.

6. Cancellation vs. refund

Canceling a subscription stops future renewals but does not, by itself, refund the current period. You retain access to your paid features until the end of the billing period already paid for. To request a refund for the current period, follow the procedure in section 4.

7. Chargebacks

Before initiating a chargeback with your bank, we ask that you contact us first so we can try to resolve the issue. Unjustified chargebacks may result in suspension of your account.

8. Changes to this Policy

We may update this Policy from time to time. The "Last updated" date at the top reflects the most recent revision. Changes apply to purchases made after the revision date.
