This Privacy Policy explains how Hassanin Yousif, trading as Oorukai.com ("Oorukai," "we," "us," or "our") collects, uses, and shares information in connection with Vertex (the "App"), a mobile game for iOS and Android. It applies to the App itself and to no other Oorukai product or website unless that product links to this policy directly.

By downloading, installing, or using the App, you agree to the collection and use of information as described in this policy. If you do not agree, please do not use the App.

1. Summary

Because this section is a summary, the numbered sections below it are the authoritative version if anything here seems to conflict.

2. Who We Are

Vertex is developed and published by Hassanin Yousif, trading as Oorukai.com ("Oorukai"). If you have questions about this policy or about how the App handles information, you can reach us at privacy@oorukai.com or through oorukai.com.

Data controller: Hassanin Yousif, trading as Oorukai.com. For the purposes of applicable data protection law (including the EU/UK GDPR), Hassanin Yousif, trading as Oorukai.com, is the data controller for the information described in Section 3, except where a third-party service listed in Section 6 acts as an independent controller of its own data (for example, Apple's or Google's handling of your payment information, which we never receive).

3. Information We Collect

3.1 Information collected automatically

When you use the App, the following information may be collected automatically by the third-party services described in Section 6, acting on our behalf:

3.2 Information stored only on your device

The following is stored locally on your device using standard app storage and is never transmitted to us or to any third party:

If you uninstall the App, this locally stored information is deleted from your device along with everything else the App stored there, subject to your device's own backup behavior (for example, an iOS/Android system backup may include this app data unless you've excluded it).

3.3 Purchase information

The App offers optional, non-consumable in-app purchases (cosmetic skins and backgrounds; no purchase affects gameplay difficulty or outcome). All purchases are billed and processed entirely by Apple's App Store or Google Play — we never receive, see, or store your payment card details, billing address, or other payment information. When a purchase completes, we receive confirmation of which item was bought and its price, which is used only to unlock that item locally on your device and, per Section 3.1, to log a corresponding analytics event. We do not operate any server-side receipt validation; the App trusts the confirmation Apple/Google's own purchase APIs provide.

3.4 Leaderboards (Apple Game Center)

On iOS, the App's leaderboards (All-Time, Friends, and Daily Challenge) are Apple Game Center leaderboards. They are real, and they involve other real players.

On Android, no leaderboard service is connected in this version, and scores stay on your device.

3.5 Information we do not collect

The App has no account system of our own — we operate no server, and there is nothing to register for. The one sign-in the App can use is Apple's Game Center (Section 3.4), which is Apple's, not ours, and which the App never initiates on its own during play.

The App does not collect or request your name, email address, phone number, physical address, government ID, or contacts. It does not access your camera, microphone, precise location, photo library, or contacts, and it has no chat, messaging, or other feature that would let you or another player submit user-generated content. The only text another player can ever see from you is the Game Center nickname you chose with Apple.

4. How We Use Information

We use the information described in Section 3.1 only to:

We do not use this information for automated decision-making that produces legal or similarly significant effects on you, and we do not combine it with any directly-identifying information such as your name or email address, because we never collect that information in the first place.

Where the GDPR or UK GDPR applies, we (or the third-party services acting on our behalf) rely on the following legal bases:

6. Third-Party Services

The App uses the following third-party services, each of which processes information under its own privacy policy, independent of this one. We encourage you to review them:

Google's Firebase services (Crashlytics and Analytics) and AdMob are all covered under Google's own overarching privacy policy in addition to the service-specific pages linked above.

We do not sell your personal information to any third party, and we do not share it with any third party for that third party's own independent marketing purposes, other than the ad-serving activity of AdMob described in Section 3.1 and Section 7, which you can influence via the consent and opt-out controls described there.

The App also includes a "More games from Oorukai" menu option, which opens our website at oorukai.com in your device's browser. That site (and any other site or app you reach through it) is outside the App and is governed by its own privacy policy and terms, not this one.

7. Advertising and Your Consent Choices

If the App detects that you're located in the European Economic Area, the United Kingdom, or Switzerland, it runs Google's User Messaging Platform (UMP) consent flow before requesting any ads that would need your consent under those regions' rules, and it will not initialize the Google Mobile Ads SDK at all until that flow resolves. You can review or change your choice at any time from Settings → Privacy Options within the App (this option only appears where Google's UMP determines it's required).

Regardless of region, you can also limit ad personalization at the operating-system level. On iOS, the App will also show you Apple's App Tracking Transparency system prompt directly, rather than only relying on you finding this setting yourself; you can allow or decline it there, or change your choice afterwards:

As noted in Section 3.1, your answer to the App Tracking Transparency prompt is what decides whether this App's ads are personalized: allow, and ad requests may use your advertising identifier; decline, and they are sent as non-personalized. Declining does not reduce the number of ads you see, and it never affects gameplay, your score, or anything you have bought. Where the UMP flow above applies, both conditions must be satisfied before an ad is personalized.

8. Data Retention

We do not operate a backend server or database of our own, so we do not directly retain any of the information described in Section 3.1 — it is retained by Google (Firebase Crashlytics, Firebase Analytics, AdMob) under their own retention schedules and settings, which you can read about in the policies linked in Section 6. Information stored locally on your device (Section 3.2) persists until you clear the App's storage, uninstall the App, or reset the device, whichever happens first.

9. Your Rights and Choices

Depending on where you live, you may have rights to access, correct, delete, restrict, or object to the processing of your personal information, to receive a copy of it in a portable format, and to lodge a complaint with your local data protection authority. Because the App has no accounts and does not tie the information in Section 3.1 to your identity, we are often not able to look up "your" data by name — the most direct ways to exercise control are:

California residents: we do not sell or share (as those terms are defined under the CCPA/CPRA) your personal information, and we have not done so in the preceding 12 months. The categories of personal information described in Section 3.1 may be disclosed to the service providers listed in Section 6 for the business purposes described in Section 4. We do not collect "sensitive personal information" as defined by the CPRA (for example, precise geolocation, government IDs, or health information), so there is no sensitive-information use to limit. You may exercise your rights to know, delete, or correct by contacting us as described above.

Nevada residents: we do not sell personal information as defined under Nevada law (NRS 603A). If you'd still like to submit a request not to sell, you may contact us at the email above.

10. Children's Privacy

The App is not directed to children under the age of 13 (or the equivalent minimum age in your jurisdiction), and we do not knowingly collect personal information from children. The App has no account creation, chat, or other feature that would let a child submit personal information to us. If you believe a child has provided us with personal information, please contact us at privacy@oorukai.com so we can investigate and, where appropriate, arrange for its deletion via the relevant third-party service in Section 6.

11. Data Security

We rely on the security practices of the third-party services listed in Section 6 (all operated by Apple or Google) to protect the information described in Section 3.1, and on your device's own operating system to protect the information described in Section 3.2. No method of transmission or storage is completely secure, and we cannot guarantee absolute security. Because we never receive your payment details (Section 3.3) or directly-identifying information (Section 3.5), our own exposure in the event of an incident is correspondingly limited to the categories of information described in Section 3.1.

12. International Data Transfers

The third-party services described in Section 6 may process and store information on servers located outside your country of residence, including in the United States, as part of Google's and Apple's global infrastructure. Where required, those companies rely on their own safeguards for cross-border transfers (such as the EU Standard Contractual Clauses); see the policies linked in Section 6 for details of each company's own approach.

13. Changes to This Policy

We may update this Privacy Policy from time to time — for example, if we add a new feature, integrate a new third-party service, or enable personalized advertising. We will revise the "Last updated" date at the top of this policy whenever we do, and for any change we consider material, we will make reasonable efforts to call it out in the App's store listing or update notes. Your continued use of the App after a revised policy takes effect constitutes your acceptance of it.
