Stelo (bundle identifier com.ootssu.pawport) is published by Shin Jungsoon. This page describes what data the app does — and does not — collect.

Summary

Stelo does not collect any personal data. Everything you do stays on your device. The app contacts no servers at all in version 1 — not for analytics, not for sync, not for crash reporting. No data is ever sent to the developer or any third party.

What stays on your device

Your stars, constellations, names you've given them, and the date each one was drawn — stored locally with Apple's SwiftData framework.
Your optional birthday (month and day only, no year), if you chose to enable the birthday-star feature during onboarding.
Your streak count and last-tick date — used to space out the daily-star spawn and surface gentle milestones in Settings.
Whether you've completed onboarding — stored in iOS UserDefaults under a single key.

What we do not collect

No name, email, phone number, or any other identifier.
No location.
No analytics events. No SDKs that report app open / engagement / errors. No TelemetryDeck, no Firebase, no Crashlytics, no anything.
No advertising IDs. Stelo does not display ads and does not show any App-Tracking-Transparency prompt because there is nothing to track.
No diary text, no usernames, no photos. Stelo doesn't ask for any of that.

Third-party services

Stelo uses no third-party SDKs in version 1. There is no list of third parties because there are none.

Children

Stelo is rated 4+ and is safe for all ages. We don't knowingly collect data from anyone, of any age.

If something changes

If a future version of Stelo ever adds optional iCloud sync, telemetry, or any other feature that involves data leaving your device, this policy will be updated before that feature ships, and the change will be opt-in by default. The "Last updated" date at the top of this page reflects the current version of the policy.
