Privacy Policy — Alchemy Codex
Last updated: August 28, 2026
This Privacy Policy describes how Alchemy Codex ("the App"), developed by Kalyana Chakravarthy Jarajapu, collects, uses, and shares information.
Information We Collect
The App does not require account creation or collect personal information directly. It uses the following third-party services, which may collect data as described in their own privacy policies:
Google AdMob — serves rewarded video ads. May collect advertising identifiers and usage data for ad delivery and personalization, subject to your consent choices (EU/UK users see a consent prompt via Google's User Messaging Platform).
Google Firebase Analytics — collects anonymized gameplay and usage events (e.g. discoveries made, screens viewed) to help us understand how the App is used.
Google Firebase Crashlytics — collects crash and diagnostic reports to help identify and fix bugs.
Google Play Billing — processes in-app purchases. Payment information is handled entirely by Google Play and is never seen by us.
Google Play Games Services — if you choose to enable Cloud Save, your Google Account is used to store and sync your game progress across devices. This is optional and can be disabled in Settings.
How We Use Information
Collected data is used solely to operate, maintain, and improve the App — including crash diagnosis, understanding feature usage, delivering ads, processing purchases, and syncing save data (if enabled).
Data Sharing
We do not sell or share personal information with third parties beyond the service providers listed above, each of which processes data under its own privacy policy:
- Google Privacy Policy (https://policies.google.com/privacy)
Children's Privacy
The App is not directed at children under 13. We do not knowingly collect personal information from children.
Your Choices
You can control ad personalization consent and Cloud Save from within the App's Settings. You can also manage app permissions and ad settings through your device and Google Account settings.
Data Retention
Data collected by third-party services is retained according to each provider's own policies. Locally, game progress is stored on your device unless Cloud Save is enabled.
Changes to This Policy
We may update this Privacy Policy from time to time. Continued use of the App after changes constitutes acceptance of the updated policy.
