Stelo is a slow, low-stimulation drawing toy. It is not a sky-map app, not an astronomy reference, and not an educational tool. The Almanac's match-against-IAU-constellations feature is meant as gentle delight, not as star-identification or navigation. Please do not use Stelo to find your way home in the dark.
Stelo is free at launch with no ads and no in-app purchases. If a paid tier is added in a future version (for example, optional cosmetic sky themes), the new terms will be published before any charge occurs. Anything you've already drawn will stay accessible in the free tier.
Your use of Stelo is also governed by our Privacy Policy. Short version: Stelo stores everything on your device only and contacts no servers in version 1.
You can delete the app at any time to stop using the service. Because Stelo stores nothing on any server we operate, deleting the app fully removes your data. There is no separate account to close, no cloud copy to delete.
We may update these terms over time. The "Last updated" date at the top reflects the current version. Continued use after an update means you accept the new version.
These terms are governed by the laws of the Republic of Korea, without regard to conflict-of-law principles. Apple's standard EULA also applies to your use of the app as a licensed application from the App Store.
