Privacy policy

Last updated: 18 August 2026

About this page

Mayoibi (“the app”) is an iPhone game developed and published by CSF INC. (“we”). This page explains what the app and this website do with information.

What we do not collect

There is no account. We never ask for your name, email address or phone number.
Your high score and settings stay on your device. They are never sent to our servers.
We have not built any analytics of our own into the app.

Advertising

The app shows ads through Google AdMob. To serve those ads, Google and its partners may collect and use:

Device identifiers, including the advertising identifier (IDFA)
Advertising data — which ads were shown, taps, and what followed
Coarse location — at the level of a city or region, not a precise position
Device model and OS version
Product interaction — which screens were seen, for example
Diagnostics — crashes, loading times and similar

None of this reaches us. It is collected and used by Google and its partners, and how long it is kept, and how it is deleted, follows Google’s policies.

For the details, please see Google’s own pages.

Ad content is limited to the general audience rating.

The tracking prompt

On iOS, we have to ask you before the advertising identifier (IDFA) can be used.

The game plays exactly the same if you say no. You will still see ads; they simply will not be matched to your interests.

You can change your answer at any time in iOS Settings → Privacy & Security → Tracking.

If you live in Europe, the UK, or certain US states

Depending on where you are, we may show a consent screen about advertising, as the law in your region requires.

You can change what you agreed to at any time from Privacy options inside the app’s Settings. That item only appears in regions where it is required.

Purchases

Removing ads is an in-app purchase handled by Apple through the App Store. We never receive your card number or any other payment details. The record of the purchase is held against your Apple Account.

Reaching this page from inside the app

You can open this page from Settings → Credits → Privacy policy.

Children

Mayoibi is written to be gentle enough for children — there is no blood and nothing gruesome. That said, it is not published in the Kids Category.

This website, and the contact form

This site collects nothing that identifies you as a visitor. There is no analytics tool on it.

What you send through the contact form — your name, a reply address, your setup, and your message — arrives as an email from our own server to us. It does not pass through any third-party form service. We use it to reply to you, and for nothing else.

To keep machines from flooding the form, that page may use Cloudflare Turnstile. The check means your device talks to Cloudflare, and technical information such as your IP address is processed there. None of it reaches us.

This is about the website. The app itself never talks to Cloudflare.

Changes to this policy

If we change it, we will update this page. For anything substantial we may also say so inside the app.
