Privacy Policy
This policy explains what data Trajectory may process on the website and in the iPhone app, and how we use and protect it.
What data we collect
On this website, we may receive your email only when you contact us. In the iPhone app, with your permission, we may process behavioral and health-related signals such as sleep, steps, activity, screen-usage categories, check-in answers, and progress metrics.
How we use data
We use data to provide product features, calculate your daily score, generate daily/weekly insights, improve reliability, and provide support. We do not sell personal data.
Permissions and control
Health and device data are used only after explicit permission. You can revoke permissions in iOS settings. You can request deletion of your account data by contacting us at hello@trajectory.app.
Retention and security
We keep data only for as long as needed to provide the service and meet legal obligations. We apply reasonable technical and organizational safeguards, but no system is guaranteed to be 100% secure.
Children and medical disclaimer
Trajectory is not intended for children under 13. Trajectory does not provide medical diagnosis or treatment and should not replace professional medical advice.
Changes to this policy
We may update this policy as the product evolves. Material changes will be reflected by updating the date above.
