Northstar is published by Roadtrip Technologies Limited. This policy explains what happens to your data when you use the app.

Your data stays on your device

Your goals, journal entries, check-ins, exercise answers and progress are stored only on your iPhone. Northstar has no account and no login, and we do not have access to this content.

On-device AI

All AI coaching runs on your device with Apple Foundation Models. Your prompts and coaching conversations are processed on the iPhone and are never sent to any server, ours or a third party's. No personal data is sent to any AI cloud service.

Purchases

In-app purchases and subscriptions are handled by Apple. To validate purchases, Northstar sends an anonymous install identifier and the App Store purchase receipt to the Roadtrip Technologies server. This is used solely to verify your entitlement to Northstar Pro. It contains no name, email or other personally identifiable information, and none of your goals, journal or check-in content.

Third parties

Northstar does not use third-party analytics, advertising or tracking SDKs, and we do not sell or share your data.

Not medical advice

Northstar is a self-improvement coaching tool and does not provide medical, psychological or therapy advice.

Deleting your data

Deleting the app removes all of its data from your device.
