Privacy Policy — Stellar: Night Sky Journal Last updated: June 2026

Overview Stellar is a personal journaling app. Your journal entries, moods, and reflections are stored privately on your device. We do not create user accounts, and your personal writing is never transmitted to our servers.

What data we collect

On your device (local only): Your journal entries, mood selections, and app preferences are stored locally on your iPhone using your device's built-in storage. This data never leaves your device unless you explicitly choose to back it up via iCloud (managed entirely by Apple).

Subscription data: If you subscribe to Stellar Unlimited, your purchase is processed by Apple and managed through RevenueCat, our subscription management provider. RevenueCat assigns you an anonymous subscriber ID and records your subscription status. No personally identifiable information is shared with RevenueCat — they do not receive your name, email, or journal content. You can review RevenueCat's privacy policy at revenuecat.com/privacy.

Anonymous usage analytics: We use PostHog, a product analytics service, to understand how people use Stellar's onboarding and subscription flow — for example, which screens are viewed and whether a trial is started. This is limited to interaction events (screen views, button taps, mood selections) and never includes your journal entry text, which always stays on your device. PostHog assigns an anonymous device identifier and does not receive your name, email, or journal content. You can review PostHog's privacy policy at posthog.com/privacy.

What we do not collect

• We do not collect your name, email address, or any contact information
• We do not read, transmit, or store your journal entries on any server
• We do not use advertising trackers, and we never sell your data to any third party

Third parties Stellar integrates two third-party services: RevenueCat, used for subscription management, and PostHog, used for anonymous product analytics. Neither service receives your journal content, name, or email address.

Children's privacy Stellar is not directed at children under 13. We do not knowingly collect data from children.

Your rights Since your journal data is stored only on your device, you have full control over it at all times. You can delete all app data by removing the app from your iPhone. For any questions about your subscription or analytics data, you can contact us and we will assist you.

Changes to this policy We may update this policy from time to time. The current version will always be available at this URL.
