4.4 Business Transfers

If Osero.gg is involved in a merger, acquisition, or sale of assets, your information may be transferred. We will provide notice before your information becomes subject to a different privacy policy.

You can request a copy of your personal data in a structured, commonly used format.

7.2 Correction

You can update your account information through your profile settings at any time.

7.3 Deletion

You can request deletion of your account and associated data by contacting us at support@osero.gg. Note that some information may be retained as required by law or for legitimate business purposes (fraud prevention, dispute resolution).

7.4 Communication Preferences & Consent

When you create an account, you may opt in to receive (a) email notifications when it is your turn in an ongoing game or when your daily streak is at risk, and (b) email about events and platform news. Both options are unchecked by default — you must affirmatively check them to consent. For each opt-in selected at signup, we record the timestamp and IP address at the moment of consent to demonstrate compliance with applicable email and privacy laws. You may withdraw consent at any time from your account settings or via the unsubscribe link in any email; we will stop sending the corresponding emails promptly. The same model applies to push notifications, which you can enable or disable at any time in your device settings or the app's notification preferences. You cannot opt out of essential service-related communications (security alerts, password resets, billing notices).

7.5 Do Not Track

Our Service does not currently respond to Do Not Track (DNT) browser signals.
