Astrologos stores the information needed to operate the service, such as account records, tokens, subscriptions, quota and usage accounting, job status, operational diagnostics, and contact messages you choose to send. Private data is anonymised or minimized as far as practical for running and maintaining a functioning operational service. Data is not sold, rented, or used for advertising, profiling, or unrelated purposes. Operational data may be used to keep the service working, diagnose failures, prevent abuse, enforce quotas, improve reliability, and understand aggregate system load. Anonymous contact messages are stored in dated log files so old messages can be deleted.
