A+ Sentinel records the account email, display name supplied by the authentication provider, membership level, login times, last activity time, feature paths used, alert preferences, billing identifiers supplied by Stripe, and messages submitted to customer support.

Sentinel does not store customer passwords. Google and customer email authentication are handled by the configured authentication provider. Payment-card details are handled by Stripe and are not stored by Sentinel.

Activity records are used to secure accounts, understand whether the service is being used, improve features and provide customer support. A shortened one-way hash may be made from an IP address for abuse prevention; the raw address is not intentionally retained in the platform database.

Customers may request access, correction or deletion by contacting support@aplussentinel.com. Retention periods and the legal business/controller details must be completed before accepting public customers.
