Alchemy Codex does not maintain its own account system. Cloud-save identity is provided entirely by Google Play Games Services, tied to your Google Account.
To delete your Play Games Services data for Alchemy Codex:
1. Open the Google Play Games app.
2. Tap your profile icon → Data management.
3. Select Alchemy Codex and choose to delete your saved game data.
Alternatively, manage or delete this data anytime via your Google Account's Data & Privacy settings: https://myaccount.google.com/data-and-privacy.
Note: your discovery progress, category counts, daily streak, and hint token balance may be synced to Google Play Games Services cloud save (if you've signed in), in addition to being stored on-device. Deleting your Play Games Services data as described above removes the cloud copy; uninstalling the app removes the local copy.
Purchase records (Google Play Billing) are held entirely by Google, not by us -- we only store a local flag on your device for which items you own, so that content unlocks correctly. To view, manage, or request deletion of your purchase history, use Google's own tools: https://play.google.com/store/account/orderhistory
For any other question about your data, contact us at kalyanachakravarthyjarajapu@gmail.com.
