Refund Policy

Last updated: April 10, 2026

Overview

We want you to be happy with your purchase. If Mermster doesn't meet your expectations, we offer a 30-day money-back guarantee on all paid licenses.

Eligibility

You may request a full refund within 30 days of your purchase date, no questions asked.

The following are always eligible for a refund regardless of timeframe:

• Duplicate purchases
• Failed license activations that cannot be resolved by our support team
• Billing errors

How to Request a Refund

Email mermster@viaelo.app with your order number or the email address used at checkout. We aim to respond within one business day.

Processing

All purchases and refunds are processed by our authorized payment provider, who acts as Merchant of Record. Refunds are issued to your original payment method and typically appear within 5–10 business days, depending on your bank or card issuer.

After a Refund

Once a refund is processed, your license key will be deactivated. You may continue using Mermster under the free tier, which includes all features with a watermark on exports.

Why We Offer This

Mermster's free tier includes every feature — the only difference is a watermark on exports. You can evaluate the full application for as long as you like before purchasing. We're confident that once you try it, you'll want clean exports. But if it doesn't work out, we'll give you your money back.
