Owldoku — Privacy Policy

Last updated: 17 September 2026 · H&H Games (HNH CO., LTD.)

The short version. Owldoku does not ask for your name, your email, or anything else that identifies you. If you allow it, the game sends anonymous notes about which puzzles are hard — that is all. You can say no, and nothing about the game changes.

1. What we collect, and only if you agree

The first time you open Owldoku, we ask whether you are willing to send usage data. Until you say yes, nothing is sent. The app ships with collection switched off, so this is true from the very first second the app runs, not just from the moment you answer.

If you agree, the game records these events:

The two tap figures are counts, not a record of where you tapped. They exist to answer one question: whether a new player can work out the controls. Twenty taps and no owl placed means we explained the game badly.

Alongside these, Google Analytics for Firebase sends a few standard events of its own that cannot be switched off individually — the first launch of the app, the start of a session, and time spent in the app — and records a randomly generated app instance identifier, your device model and operating system version, your app version, your language setting, and a country derived from your IP address. Your IP address itself is not stored.

2. What we never collect

Owldoku has no accounts, no social features, and no way for anyone to identify you from the data above.

3. Why we collect it

Owldoku has 614 puzzles arranged so that each one builds on a technique taught by the ones before it. That ordering is our best guess, and a puzzle placed too early is indistinguishable, from the outside, from a puzzle that is simply unfair. Knowing which technique players actually needed help with, and where, is how we correct the difficulty curve. It is used for nothing else.

4. Who processes it

Data is processed by Google LLC through Google Analytics for Firebase, acting as our processor. This means it is stored on Google's servers, which are located outside the Republic of Korea and may be outside your own country. Google's handling of this data is described in the Firebase Privacy and Security documentation.

We do not sell data, and we do not share it with advertisers or any other third party.

5. How long it is kept

Event data is deleted automatically according to the retention period set in our Firebase project. Aggregate statistics — counts and averages that describe no individual — may be kept without a time limit.

6. Your choices

You can change your mind at any time: open Settings in the game and switch Usage statistics off. Collection stops immediately, including the automatic events described in section 1.

Declining, or later switching it off, changes nothing about the game. Every puzzle, every feature, and every hint stays available. We do not ask again.

If you are in the European Economic Area or the United Kingdom, our legal basis is your consent (GDPR Art. 6(1)(a)), and you may withdraw it as described above. You also have the right to request access to, correction of, or deletion of your data, and to lodge a complaint with your supervisory authority. Because we hold no identifier that connects the data to you personally, we may be unable to locate your specific records — in that case, switching collection off stops any further data being sent.

7. Children

Owldoku is not directed at children under 13, and we do not knowingly collect data from them. If you believe a child has sent us data, contact us and we will remove what we can identify.

8. Changes

If we change what we collect, we will update this page and, where the change is significant, ask again inside the app.
