Icos ("we", "our", or "us") operates the Icos mobile application (the "App"), a daily puzzle game available on iOS and Android. This Privacy Policy explains how we collect, use, and protect your information when you use the App.
When you create an account, we collect:
You can use the App without creating an account (anonymous/guest mode). In this case, we assign a random anonymous identifier with no personal information attached.
To provide the game experience, we collect:
We automatically collect limited device information:
The App stores data locally on your device for offline functionality:
This local data is not transmitted to our servers and is deleted when you uninstall the App.
The App can use Firebase Analytics and Firebase Crashlytics (Google) to record which features are used (for example puzzle started or completed, group created or joined, sign-in method) and to report crashes and performance. These events, crash reports and performance data are linked to your anonymous or account user identifier (not your name or email), and are used for analytics and to keep the App working. This reporting is only active in builds where we have configured Firebase; in other builds the App sends no analytics or crash data to Firebase. Crash reporting is switched off in debug builds.
If you allow notifications, the App schedules the daily puzzle reminder and streak reminder on your device itself; these local reminders do not use a push token or send anything to a server. In builds where Firebase is configured, the App also subscribes your device to a Firebase Cloud Messaging topic for the daily puzzle announcement, which uses a Firebase-generated device registration token. You can turn notifications off in the Profile screen or in your device settings.
| Purpose | Data Used |
|---|---|
| Provide the game experience | Game data, account info |
| Maintain your streak and statistics | Puzzle completion records |

| Moderation of groups and names | Reports you send, display and group names |
The list of users you have blocked is stored with your account so that blocking works across your devices, and it is deleted with your account.
We do not sell, rent, or share your personal data with third parties for advertising or marketing purposes.
We use the following service providers to operate the App:
If you sign in with Google or Apple, those providers process your authentication according to their own privacy policies:
We may disclose information if required by law, court order, or to protect our rights and safety.
We implement industry-standard security measures:
You have the right to:
If you are in the European Economic Area (EEA), you have additional rights under GDPR, including the right to data portability and the right to lodge a complaint with your local data protection authority.
If you are a California resident, you have rights under the CCPA, including the right to know what personal information is collected and the right to request deletion.
The App is not directed to children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided us with personal information, please contact us and we will promptly delete it.
Your data may be processed and stored on servers located in the United States. By using the App, you consent to the transfer of your information to the United States, where data protection laws may differ from your country of residence.
We may update this Privacy Policy from time to time. We will notify you of material changes by updating the "Last Updated" date at the top of this page and, where appropriate, through in-app notification. Your continued use of the App after changes constitutes acceptance of the updated policy.
