Chainfall Privacy Policy

Last updated: October 2026

This policy covers Chainfall, a mobile Chain Reaction game for iOS and Android. It explains what information the game collects, why, and how you can control or delete it.

Information we collect

Account and identity. Chainfall uses Unity Authentication. By default you play as a guest, which creates an anonymous player ID stored only on your device. You may optionally link a Unity Player Account (email or social sign-in through Unity’s own sign-in flow) to keep your progress across devices. We never see or store your sign-in password — that is handled entirely by Unity’s authentication service.

Gameplay and progression data. Your trophies, level, XP, coins, diamonds, match history, quest progress, season standing, and cosmetic collection are stored against your player ID in our backend (Supabase) so your progress syncs across devices and ranked results can be verified fairly.

Advertising identifiers. Chainfall shows optional rewarded video ads through Unity LevelPlay (ironSource mediation) in exchange for in-game coins or diamonds. On iOS, the game asks for App Tracking Transparency permission before requesting your advertising identifier (IDFA); you can decline this and still watch ads, just without personalized targeting. On Android, the mediation SDK may use the Android advertising ID under the same conditions. We do not control how individual ad networks mediated through LevelPlay use this data beyond showing you ads — see Unity’s and ironSource’s own privacy documentation for details on their mediation partners.

Analytics. We use first-party analytics to understand gameplay patterns (for example, which modes are played, session length, and crash/error reporting) so we can improve the game. This data is tied to your anonymous player ID, not to your real-world identity.

Local-only data. Local notification reminders, audio and display settings, and the one-time tutorial state are stored only on your device and are never transmitted to us.

What we do not collect

Chainfall does not require your real name, phone number, or physical address to play. The Shop and in-app purchases are currently preview-only and non-functional — no payment information is collected or processed by Chainfall at this time.

Children’s privacy

Chainfall is not directed at children and is configured to report itself as a non-child-directed app to its ad mediation partners (COPPA = No). If you believe a child has provided us with personal information, contact us using the details below and we will delete it.

Data deletion

You can delete your account at any time from Profile → Settings → Account → Delete account. This removes your Unity Authentication account and your synced progress from our backend, and clears saved data on that device. If you’d like to confirm deletion or request removal of data we may still hold (for example, in backups or fraud-prevention logs), email us and we’ll handle it directly.

Changes to this policy

We may update this policy as Chainfall adds features (for example, when real-money purchases are connected). Material changes will update the “Last updated” date above.
