Refund and cancellation

Last updated: 28 October 2026

Every installation of Arka Glycan includes a 30-day free trial with all features, so you can test it on your own data before you buy. We still want you to be satisfied with your purchase.

Refunds

• Within 14 days of payment, you can ask for a full refund of a new subscription or perpetual licence for any reason.
• After 14 days, payments are not refundable, except as below or where the law requires otherwise.
• Duplicate or mistaken payments are refunded in full.
• If we cannot deliver your licence key, or the software does not run on a supported system and we cannot fix it within 30 days of your report, we refund the payment in full.

When a refund is made, the licence key is cancelled and must no longer be used.

Cancelling a subscription

• Subscriptions do not renew automatically. To renew, you buy a new year; there is nothing to cancel.
• If you no longer need Arka Glycan, simply do not renew. After expiry it keeps working for 14 days, then becomes read-only: you can still open and export every past analysis.

How to ask

Write to hello@arkaglycan.com with your payment reference. Approved refunds are made to the original payment method, usually within 5–7 working days; the time your bank takes to credit it may vary.
