SkyProfile is made by Marvin Manu. This policy explains what happens to your information when you use the SkyProfile app on iPhone or Android.
SkyProfile does not collect, store or share any of your data. There is no account and no sign-up, and nothing you enter leaves your phone.
Names, birth dates, birth times, birth places, journal notes and settings are saved only on your device. Every chart and reading is calculated on the device. We can't see this information, and it is never sent to us or anyone else.
If you choose to save a chart image, SkyProfile asks for permission to add it to your photo library. It only adds the images you make. It never reads or uploads your photos.
Daily lines, weekly recaps and sky alerts are scheduled on your device. No notification service receives your chart.
The app may check our update service (Expo) for a newer version of its own code. This check sends technical details such as the app version and platform, but no personal information or chart data.
SkyProfile has no ads, no analytics, no crash reporting and no tracking of any kind.
Images you share go only where you send them, through your phone's own share sheet.
SkyProfile does not knowingly collect information from anyone, including children.
Delete a saved chart inside the app, or delete the app to remove everything it stored.
If this policy changes, the new version will be posted on this page with a new date.
