Subscription and refund policy

Last updated: 31 October 2026

How Monitor and Pro subscriptions are billed, renewed, cancelled and refunded.

1. Who this applies to

This policy applies to Monitor and Pro bought on aishelf.tech from MARKAPP SINGLE MEMBER P.C., as one-time access or as a recurring plan, by companies and by individuals. Managed packages follow their order form. Nothing in this policy limits rights that the consumer law of the country where you live gives you; where that law gives you more, it applies.

2. Paying

Access is paid in advance, in US dollars plus VAT where it applies. One-time access buys 1 month or 12 months and never renews; we email you 3 days before it ends. A recurring plan renews automatically at the end of each month or year until you cancel; we email you 30 days before each yearly renewal and 30 days before any price change. Your runs start once your payment reaches us, usually within one business day. Every payment and every refund gets an invoice, receipt or credit note by email. Runs not used within a period expire.

3. Cancelling a recurring plan

Cancel at any time from your account page, online, in a few clicks; you do not need to call or write to us. No further payment is taken. Your plan stays active until the end of the period you have paid for; then your results stay available to export for 90 days. One-time access never renews, so there is nothing to cancel.

4. If you buy for yourself: 14 days to change your mind

If you buy as an individual, not for a business, and you live in the European Union, the United Kingdom or another country whose law gives the same right, you can withdraw from your purchase within 14 days of it, without giving a reason. Because Shelf by Markapp is a service that starts when you ask for it, at checkout you ask us to start straight away and confirm that you understand this: if you withdraw after the service has started, we refund what you paid minus a share for the service we provided until you told us.

To withdraw, email adtech@markappmedia.site with your name, account email and the date of the payment, for example: “I withdraw from my purchase of Shelf made on [date].” We refund you within 14 days of your message, to the payment method you used, at no cost to you.

5. Refunds for everyone

  • First payment: if no run has finished on your account, you can ask for a full refund of your first payment within 14 days of it.
  • A renewal you did not mean to keep: if a recurring plan renewed and no run has started in the new period, ask within 7 days of the renewal and we refund it in full and end the plan.
  • Other renewals and one-time access: not refunded for the unused part of a period, because your access stays open until the period ends, unless the law where you live requires otherwise.
  • Our errors: if we charged you twice or charged the wrong amount, we refund the difference in full.
  • Service failures: if a run you paid for could not be completed, we re-run it at no cost, or refund that period if we cannot.

6. How refunds are paid

Ask for a refund at adtech@markappmedia.site. Refunds go back to the payment method you used, through Revolut, in US dollars; your bank may convert the amount. We send the refund within 14 days of approving it, and once your original payment has reached us; it can take up to 10 more business days to appear on your statement. We issue a credit note for every refund. Please write to us before disputing a payment with your bank, so we can fix it quickly.

7. Failed payments

If a renewal fails, Revolut retries it and we tell you by email and in the app. You have 7 days to pay, for example with another card from your account page. After that, scheduled runs pause until the amount is paid; your past results stay available.

8. Plan changes

On a recurring plan, an upgrade from Monitor to Pro applies at once; we charge the difference for the rest of the current period at once. A downgrade, or a switch between monthly and yearly billing, applies at the end of the current period, with no refund for the period already paid. With one-time access, choose the plan you want when you buy your next period.

9. Complaints

Write to us first at adtech@markappmedia.site; we answer within 5 business days. If you buy as an individual, you can also contact the consumer authority of the country where you live. In Greece this is the Consumer Ombudsman (Συνήγορος του Καταναλωτή).
