Privacy Policy for Firefly Run

Effective date: November 10 2026

Firefly Run ("the game") is published by Ezero Collective ("we", "us"). This policy explains what information is handled when you play.

Summary

• You do not need an account, and we do not collect or receive any personal information about you.
• Your game progress stays on your device.
• The game shows ads through Google AdMob: optional rewarded videos, and an occasional full-screen ad between flights. Google collects some device information to deliver those ads.

Information stored on your device

The game saves the following on your device only:

• your journey progress, scores, Glow, upgrades, spirits and stored powers
• your missions, daily gift and flight journal
• your settings (sound, music, vibration, difficulty)

This information is never sent to us or to anyone else, and it is not included in device backups. Uninstalling the game or clearing its data in your device settings deletes it permanently.

Advertising (Google AdMob)

The game shows two kinds of ads, both served by Google AdMob, a service of Google LLC:

• Rewarded videos, which play only when you choose to watch one, for example to rekindle your swarm, double your Glow or add a power to your supplies.
• Full-screen ads between flights, which can appear after a flight has ended and never during one.

To serve and measure ads, and to prevent fraud, Google may collect and process:

• your device's advertising ID
• your IP address, which can indicate your approximate location
• device information, such as model, operating system version and language
• how you interact with ads, and diagnostic and performance data

Google handles this information under its own privacy policy: https://policies.google.com/privacy. More detail on how Google uses information from apps that use its services: https://policies.google.com/technologies/partner-sites.

We do not receive this information, and we do not sell personal information for money. Under some US state privacy laws, letting Google use this information for personalised ads can count as "selling" or "sharing" it. You can opt out, as described below.

Your choices about ads

• European Economic Area, United Kingdom and Switzerland: when you first open the game you are asked whether you consent to the use of your data for advertising. You can change your choice at any time in the game under Settings > Ad choices.
• US states with privacy laws (such as California, Colorado, Connecticut, Virginia and others): you can opt out of the sale or sharing of your data for personalised ads at any time in the game under Settings > Ad choices. You will still see ads, but they won't be personalised.
• All regions: in your device settings (Settings > Google > Ads, or Settings > Privacy > Ads) you can reset or delete your advertising ID, or turn off ad personalisation.
• Rewarded videos are always optional. The whole game can be played without watching one.

Children

The game is not directed to children under 13, and we do not knowingly collect personal information from children. If you believe a child has provided personal information through the game, contact us and we will help.

Your rights

Depending on where you live, you may have rights to access, correct, delete or restrict the use of your personal information. Because we do not collect or store personal information, we hold nothing to provide or delete. Game data is on your device and under your control. For information collected by Google for advertising, use the controls described above or Google's tools at https://myaccount.google.com.

Changes to this policy

If this policy changes, the updated version will be published on this page with a new effective date.
