Privacy Policy for Coin of Ages

Last updated: April 23, 2026

Short version: Coin of Ages collects no personal data by default. All game progress is stored locally on your device. The game sends a small number of anonymous gameplay milestones (era reached, prestige) to Google Analytics. If you choose to sign in with Google Play Games, your save data is also uploaded to your Google Play account so you can restore it on other devices. Sign-in is optional — you can play the entire game without an account. No advertising networks are used.

Overview

Coin of Ages ("the game", "the app") is a single-player idle game developed as an independent title. This policy explains what data the game does and does not collect.

Data We Collect

We collect no personal data. Coin of Ages does not collect, transmit, or share:

Your name, email address, or contact information
Device identifiers or advertising IDs
Location data
Purchase history (the game has no in-app purchases)
Any other personally identifiable information

Anonymous Gameplay Analytics

To help us understand how players progress through the game and improve balance and pacing, Coin of Ages sends a small number of anonymous gameplay milestone events to Google Analytics 4.

What is sent:

The event name (for example, era_reached or prestige)
The era number associated with the event
A randomly-generated install ID that is created on first launch and stored locally — it is not your device ID, your advertising ID, or linked to any account

What is not sent: your name, email, device identifiers, advertising IDs, location, contact information, or any content you create. We do not log or store IP addresses on our end; any transient network-level information is handled by Google Analytics per their policy.

These events are fire-and-forget: failures are silently dropped and never affect gameplay. If you reset progress or uninstall the game, the install ID is regenerated on next launch. Data sent to Google Analytics is governed by Google's Privacy Policy.

Google Play Games Sign-in (Optional)

Coin of Ages offers optional sign-in with Google Play Games to enable cloud save. Sign-in is entirely optional — the game is fully playable offline without ever signing in. If you choose not to sign in, none of the data described in this section is collected.

If you sign in, the game receives the following from Google Play Games:

Your Play Games display name (your gamer tag — not necessarily your real name)
Your Play Games player ID (a Google-assigned identifier, not linked to your email or other Google services from our perspective)

This information is used only to display your name in the game's Settings panel and to associate your cloud save with your Google account on Google's servers. We do not transmit, share, or store this information ourselves outside of the device.

Cloud Save

When you are signed in with Google Play Games, the game uploads your save data to Google's Saved Games cloud storage. This save data contains the same information described in the Local Save Data section below — your era, balance, upgrade state, prestige count, relics, and preferences. It does not contain your name, email, or any other personal information.

Cloud save data is:

Stored by Google in your personal Google Play Games account, scoped to Coin of Ages
Uploaded automatically when you advance an era, prestige, or close the game
Downloaded automatically when you sign in on a new device
Subject to Google's Privacy Policy

To delete your cloud save: you can either (1) delete it through the Google Play Games app on your device (Settings → Delete Play Games account & data), or (2) email us at the address below to request deletion.

To sign out: Google Play Games does not allow apps to programmatically sign you out. To sign out, open the Google Play Games app on your device and sign out from there, or sign out of your Google account on the device.

Local Save Data

Coin of Ages saves your game progress locally on your device. This save file contains:

Your current era, currency balance, and upgrade state
Prestige count and relic collection
Audio and haptic preferences
Timestamps used to calculate offline earnings

This data never leaves your device. It is not transmitted to any server and is not accessible to us.

To delete your save data: Use the "Reset Progress" option in the Settings panel within the game, or uninstall the app.

Third-Party Services

Coin of Ages uses the following Google services:

Google Analytics 4 — receives the anonymous gameplay milestone events described above (always active)
Google Play Games Services — provides sign-in and cloud save (active only if you choose to sign in)

We do not integrate with any advertising, social media, or other data collection services.

Children

Coin of Ages does not knowingly collect information from children. As the game collects no personal data from any user, no special handling for children is required beyond this statement.

Changes to This Policy

If we add features in future versions that involve data collection (such as optional cloud save or analytics), this policy will be updated and users will be notified via an in-app notice before any new data collection begins.
