Privacy Policy

This policy applies to the Egg Island (Đảo Trứng) game on Android and iOS.

1. Overview

Egg Island does not require registration with an email address or phone number. Most game progress, including currency, pets, quests, and settings, is stored locally on your device. Some online features and advertising services process data as described below.

2. Data we process

On-device data

Game progress, settings and consent choices are stored on your device. The game does not ask for your date of birth. On older installs that once entered a birth year, that value stays on the device and is never sent to any server.

Leaderboard

If you enable the leaderboard, the game sends a random player identifier, display name, scores, and technical match metrics to Supabase. This data is used to display rankings, validate scores, and limit cheating. Your display name and scores may be visible to other players.

Advertising

The game uses Google AdMob to provide interstitial and rewarded ads. Depending on your device, region, and consent choices, Google and its advertising partners may process IP address, device information, advertising identifiers, ad interaction data, and diagnostics to deliver and measure ads, prevent fraud, and comply with law.

Where required, the game uses Google User Messaging Platform (UMP) to request and store your advertising choices. You may revisit these choices under Settings → Privacy → Ad privacy options when legally required.

The game's AdMob account is linked to Firebase. Through that link AdMob shares ad impression counts and their estimated revenue with Firebase Analytics, so we can tell which ad placements are worth keeping. This is data about the ads, not a profile of you.

Analytics and diagnostics

The game may use Firebase Analytics and Firebase Crashlytics to understand feature usage and fix errors. Collection is enabled only after you make a consent choice in the game. Event data is filtered to exclude display names, email addresses, phone numbers, and precise location.

Recorded events cover: the start and end of a run (score, duration, merge count, highest pet tier, reason the run ended, and the in-game currency it yielded), skill activations, tutorial steps, ad interactions, and in-game currency transactions. This describes how you play, not anything you type.

The game also records when you move between its screens — from the island to the shop, for example — along with how long each was open, so we can find the parts that are awkward to use. These are the game's own fixed screen names, not anything you viewed.

Finally, pet upgrade milestones are recorded: levelling up, evolving, upgrading a skill, including the times you wanted an upgrade and lacked the materials for it. This is what lets us balance the difficulty.

Alongside events, a few profile attributes are stored against the pseudonymous identifier Firebase generates: the equipped pet, its evolution stage, whether the tutorial is complete, and the range of runs played and range of high score. Those numbers are grouped into bands (for example “5–19 runs”, “1,000–4,999 points”) rather than sent exactly, so the profile is never narrow enough to single you out.

If you withdraw consent, the game stops collecting and asks Firebase to delete the data already gathered on your device.

3. Why we process data

4. Service providers

We do not sell your personal information.

5. Retention and deletion

Local progress remains until you clear app data or uninstall the game. Leaderboard data is retained to maintain rankings and anti-fraud history until deleted upon request. You may delete leaderboard data in the game or follow the instructions on our data deletion page. Service providers may retain data as needed for operations, security, fraud prevention, and legal obligations.

6. Your choices and rights

7. Children

Egg Island is intended for players aged 13 and older and does not knowingly collect personal data from children under 13. Because the game does not ask for an age, advertising is treated in the most conservative way for every player. If you believe a child has provided us with data, please contact us so it can be reviewed and deleted.

8. Security and international transfers

We use reasonable technical safeguards, but no transmission or storage method is completely secure. The providers above may process data outside your country under their applicable data protection mechanisms.

9. Policy changes

We may update this policy when the game or legal requirements change. The latest revision date will appear at the top of this page.
