Refund Policy
How we handle deposits, milestone payments and monthly retainers if a project changes, pauses, or ends earlier than planned.
Last updated: 6 August 2026
1. Overview
Kervon LTD aims to deliver work that's worth what you paid for it. This policy sets out when a refund applies across our three services — App Development, Growth & ASO Marketing, and AI & Automation — and when it doesn't. It should be read alongside our Terms of Use, which take precedence if the two ever conflict, and applies unless a specific written agreement with a client says otherwise.
2. App Development projects
Development work is billed against milestones agreed before the project starts.
- Deposit — refundable in full if we haven't yet started scoping or design work; non-refundable once work has begun, though any milestone not yet due won't be charged.
- Delivered milestones — non-refundable once a milestone — a design file, a working build, a completed feature — has been delivered and accepted, since it reflects work already done.
- Cancelled mid-project — you're only charged for the proportion of the current milestone actually completed.
3. Growth & ASO Marketing retainers
Retainers are billed monthly, in advance.
- If you cancel with the notice period set out in our Terms of Use, you won't be billed for the following month.
- We don't refund the current month's fee once that month's work is underway — by that point our time and any live campaigns are already committed.
- Paid advertising spend passed through as part of a retainer goes directly to the ad network or platform and isn't refundable by Kervon once a campaign has gone live, in line with that platform's own terms.
4. AI & Automation engagements
Where an AI feature is delivered as part of a fixed-scope build, it follows the App Development terms in Section 2. Where it's delivered as an ongoing engagement — for example, continued tuning after launch — it follows the retainer terms in Section 3.
5. When we owe you a refund
If we fail to deliver a milestone or a month of retainer work to the standard set out in your agreement, through fault of our own, and can't put it right within a reasonable time, we'll offer a partial or full refund for the portion of work not properly delivered — assessed case by case.
6. When we don't
We don't refund for outcomes outside our control, such as an app store's own review or ranking decisions; delays caused by late feedback, missing assets, or access we didn't receive from the client; or a change of mind after a milestone has already been delivered and accepted.
7. Chargebacks
If something on an invoice looks wrong, please talk to us first — email clientservice@kervonapps.com and we'll look into it. Raising a chargeback with your bank or card provider before giving us the chance to resolve it directly may result in work being paused while the dispute is settled.
8. How to request a refund
Email clientservice@kervonapps.com with your project name and invoice reference, and what you'd like reviewed. We aim to respond within 5 business days, and where a refund is due, to process it within 10 business days to the original payment method.
9. If we can't agree
If a refund request is declined and you'd like it looked at again, you can ask for it to be reviewed by a senior member of the Kervon team, or propose mediation through an independent third party both sides agree on. We'd rather resolve a disagreement directly than let it become a longer dispute.
10. Changes to this policy
We may update this policy from time to time; changes are reflected by a new "Last updated" date above. The version in effect when your service agreement was signed governs that engagement.
