Questions about a Horizon Launcher build, a correction to a guide, or a download that misbehaved on your phone: write to us and a human who has actually run the prepare process will answer.
For download and install problems, include your phone model, your Android version, which build you picked (ARM64 or x86) and which renderer you selected in Settings. Those four details solve most mysteries in one reply.
General questions and feedback: hello@launcherhorizon.com. Build problems and safety reports: support@launcherhorizon.com. We read everything and reply to most messages within two working days.
