Privacy Policy
The short version: we collect nothing.
This policy applies to all apps published by Good Faith Studio: Worship Assist and Mizar: Star Battle Puzzle.
What we collect
Nothing. Our apps do not collect, store, or transmit any personal information to us. There are no accounts and no sign-up.
Tracking and ads
None. We do not track you, we show no ads, and we include no analytics or third-party advertising or tracking software of any kind.
Data on your device
Everything an app remembers is saved on your device and never sent to us or anyone else. Removing the app removes it.
- Mizar saves your settings and puzzle progress, so it remembers where you left off.
- Worship Assist saves your settings, the songs you've downloaded, and your mixes and unsaved chart work. The library link you paste in — which includes the key to your team's storage — is kept in your device's secure storage (the Keychain on Apple devices).
Network
Mizar works fully offline and makes no network connections at all.
Worship Assist connects only to the cloud storage your team chose (such as Amazon S3 or Backblaze B2). Everyone uses it to download songs and charts, and to save what the team makes there — arrangements, set lists, mashups and charts — along with the name you give the app, so your team can see who changed what. The host also uses it to add and publish songs. That storage belongs to your team, not to us; we never see it or anything in it. Its provider's own privacy policy covers it. Once a song is downloaded, it plays offline.
On Mac, Windows and Android it also checks this website about once a day to see whether a newer version is out. That check reads one small public file and sends nothing about you.
Children
Because we collect no data at all, our apps are safe for players of any age. We never knowingly collect information from anyone, including children.
Changes
If this policy ever changes, we will update this page and revise the date below.
