Privacy Policy
Last updated: April 6, 2026
This Privacy Policy describes how ARIS (“we,” “us,” or “our”) collects, uses, and protects information when you use the ARIS mobile application, web application, and related services (collectively, the “Service”).
Information We Collect
Section titled “Information We Collect”Account Information
Section titled “Account Information”When you create an ARIS account, we collect:
- Email address — used for authentication and account recovery.
- Display name — optional, used within the app.
- Authentication provider — whether you signed in with Google, Apple, or email/password.
We support anonymous (guest) accounts. You can use core features without providing any personal information. Creating a full account unlocks cloud sync and additional features.
Equipment Profiles
Section titled “Equipment Profiles”Equipment profiles you create (device names, driver configurations, imaging parameters) are stored in Firebase Firestore to enable sync across your devices. These profiles contain equipment configuration data only — no personal information.
Error Reports
Section titled “Error Reports”We use Sentry for crash and error reporting. When the app encounters an error, Sentry may collect:
- Device type and operating system version.
- App version.
- Stack trace and error context.
- General device state (memory, battery level).
Sentry error reports do not include your images, location coordinates, account email, or any personal information.
Information We Do Not Collect
Section titled “Information We Do Not Collect”We want to be explicit about what we do not collect:
- Your images. Captured images are stored on your backend and your local device. We never upload, access, or process your astrophotography images.
- Your location. ARIS does not track your GPS location. Observatory coordinates that you manually enter into equipment profiles are stored only in your profile data for astronomical calculations.
- Usage analytics. We do not track which screens you visit, how long you use the app, or your interaction patterns. We collect error reports only.
- Equipment telemetry. Commands sent to your equipment and telemetry received from your equipment stay on your local network between the app and your backend.
How We Use Your Information
Section titled “How We Use Your Information”We use collected information for the following purposes:
- Authentication and account management — to let you sign in and manage your account.
- Cross-device sync — to sync your equipment profiles across your devices.
- Error diagnosis — to identify and fix bugs and crashes.
- Service communication — to contact you about critical service updates (rare, only when necessary).
We do not sell, rent, or share your personal information with third parties for marketing purposes.
