Terms of use & refunds

Last updated: 21 September 2026

The short version: MaBayn is a planning tool, your data stays with you, Pro is a one-time purchase, and you can get a full refund within 14 days.

What MaBayn is

MaBayn is a personal budgeting and planning tool. It is not financial, investment, tax or legal advice, and it does not move money. Exchange rates are indicative mid-market rates from third-party sources and may differ from what your bank or exchange house charges. You are responsible for the decisions you make using it.

Free and Pro

The core app is free and needs no account. MaBayn Pro is a one-time purchase of 49 AED (about US$13, charged in AED) that unlocks Pro features — currently, budgeting each category in its own currency. Features marked “coming” are planned without a guaranteed date. If the remittance planner or the money calendar is released, it is added to Pro and your licence includes it at no extra cost. Sync between devices is planned but not promised as part of Pro: if it needs a paid online service, it may be offered separately, and we will say so before it launches.

What “lifetime” means

A Pro licence has no expiry and no renewal fee. It covers the Pro features available when you buy and the updates to Pro we release for as long as MaBayn is offered. One licence can be active on up to three devices at a time; free a slot by removing Pro from a device in the app, or by emailing us.

Purchases and refunds

Purchases are processed by Lemon Squeezy as merchant of record, and its terms apply to payment, tax and invoicing. If MaBayn Pro isn’t right for you, email orders.mabayn@gmail.com within 14 days of purchase for a full refund — no questions asked. A refunded licence is deactivated.

Lost licence or new device

Your licence key is in your purchase email and in your Lemon Squeezy order history (app.lemonsqueezy.com/my-orders). On a new device, open MaBayn Pro and paste the key. If all three slots are taken by devices you no longer have, email us and we’ll reset them.

Your data and backups

Your records are stored only on your device (see Privacy), and we cannot recover them. Export backups regularly; keeping them is your responsibility.

If MaBayn stops operating

Your records are on your device and in your backups, not with us, so they won’t be lost. An installed copy of the app should keep working offline, but features that depend on outside services — live exchange rates, activating Pro on a new device, and updates — may stop. We’d aim to give notice on this site.

Acceptable use

Don’t attempt to bypass licensing, resell licences, or interfere with the service.

Liability

MaBayn is provided “as is”. To the extent the law allows, we are not liable for losses arising from its use, including lost data or decisions based on its figures. Nothing in these terms limits rights you have under consumer law that cannot be excluded.

Changes and contact

We may update these terms; the date above shows the current version. Questions: orders.mabayn@gmail.com.
