Privacy Policy

Last updated: 26 August 2026

The short version. The game has no accounts. We never ask for your name, your email address or your phone number, and we could not identify you if we wanted to. What we do collect is anonymous gameplay statistics and the advertising identifier your phone gives to apps — the same one every ad-supported app uses — so that ads can be shown and paid for.

Who we are

This game is published by ONELA MARKET CO., LTD. (บริษัท โอเนล่า มาร์เก็ต จำกัด), a company registered in Thailand under number 0505568000722, trading as Onela Games.

Registered address: 54/1 Traswong Road, Mueang Chiang Mai, Chiang Mai 50000, Thailand.

For any question about this policy or your data, write to onelamarket@gmail.com.

What the game collects

There is no sign-up, no login and no user profile. We collect three things, and nothing else.

WhatWhyWho processes it
Gameplay events
Which level you started, which wave you reached, gold earned, whether you won or lost, when you opened the shop.
To understand which levels are too hard or too easy, and to fix the ones that are. Google Firebase Analytics
Advertising identifier and device data
Your device's resettable advertising ID, IP address, device model, operating system version and language.
To show rewarded video ads, to avoid showing you the same ad repeatedly, and to measure what an ad earned. Unity LevelPlay, and through it ironSource, Unity Ads and Google AdMob
Purchases
Which product was bought and the price your store displayed.
To grant what you paid for, and to know which offers people actually want. Apple App Store, Google Play — we never see your card details

We do not collect your name, email address, phone number, contacts, photos, files, microphone, camera or precise GPS location. The game asks for no such permission, and you can verify that in the permission list on its store page.

Advertising, and how to say no

The game shows rewarded video ads only — the kind you choose to watch in exchange for something. There are no banners and no ads that interrupt play. You never have to watch one.

Ads are supplied through Unity LevelPlay, which requests them from ironSource, Unity Ads and Google AdMob. These partners use the advertising identifier to select ads and to count them. Their own privacy policies apply to that processing:

You can switch personalised advertising off at any time, from your phone.

Ads still appear after you opt out — they are simply less relevant to you.

Children

This game is not directed at children under 13, and we do not knowingly collect data from them. If you believe a child has provided us with data, write to us at the address above and we will delete it.

Where data goes, and for how long

Firebase Analytics data is processed on Google servers, which may be outside your country, and is retained for 14 months before being deleted automatically. Advertising partners retain data according to their own policies, linked above.

Your rights

Depending on where you live, you may have the right to ask what data we hold about you, to have it corrected, or to have it erased. Because the game holds no account and no identifier we can tie to a person, the practical way to exercise these rights is to reset or delete your advertising ID, as described above — that severs the only link between the data and your device. If you would like us to act on a request directly, write to onelamarket@gmail.com and we will answer within 30 days.

Changes to this policy

If we change what the game collects, we will update this page and change the date at the top. The date is the honest test: if it has not moved, nothing has changed.
