PRIVACY POLICY — DEVSTADIUM
Last updated: August 22, 2026
Mochi Studio ("we," "us," "our") operates DevStadium (the "App"), a mobile trivia game for developers. This policy explains what data the App collects and how it's used.
NO ACCOUNT REQUIRED
DevStadium does not require you to create an account, sign in, or provide any personal information to play. There is no name, email, or phone number collected by the App itself.
WHAT WE COLLECT
Usage analytics. We use Firebase Analytics to understand how the App is used — for example, which game rounds are started, questions answered, and results viewed. This data is tied to your device, not to your identity, and is not used to track you across other apps or websites.
Device attestation. We use Firebase App Check to verify that requests to our servers come from a genuine install of the App, not from a bot or script. This checks your device's integrity (via Apple App Attest on iOS or Google Play Integrity on Android) and does not collect personal information.
Leaderboard scores. When you play a topic set, your score, an anonymous device identifier, and a timestamp are recorded so we can show leaderboards (e.g., "you beat X% of players on this set"). This identifier is not linked to your name, email, or any other personal information, and cannot be used to identify you.
Question reports and feedback. If you report a question or submit feedback through the App, we collect the content you provide (e.g., a description of the issue) so we can review and improve the question bank.
WHAT WE DON'T DO
We don't collect your name, email, or contact information.
We don't sell your data.
We don't use your data for third-party advertising.
We don't require or store login credentials.
DATA RETENTION
Leaderboard and analytics data is retained for as long as needed to operate the leaderboard and improve the App. You can't currently request deletion of a specific record because it isn't tied to an identifiable person — the anonymous device identifier can't be traced back to you by us or anyone else.
CHILDREN'S PRIVACY
DevStadium is not directed at children under 13. We do not knowingly collect personal information from children under 13.
CHANGES TO THIS POLICY
We may update this policy as the App changes. The "Last updated" date at the top will reflect the most recent revision.
