These Terms of Service govern the use of Sentry's software-as-a-service solutions for application monitoring. Users grant Sentry a non-exclusive, worldwide license to use their Service Data for providing, maintaining, and improving the service, and for developing new products, especially with non-identifying data. Sentry can unilaterally modify the terms, with continued use constituting acceptance, but users can terminate if they object to changes taking effect before renewal. Users must be at least 16 years old and are responsible for their data.
