Network, Advertising, and Analytics
Chemistry Box is designed to work offline after installation. The app does not use analytics SDKs, advertising identifiers, background network requests, AdSense, Supabase, or account authentication for gameplay.
The app may include user-initiated links to wordcork.com or to email support. Those actions are handled by your browser, email app, or operating system and may be subject to those services' own policies.
Support Emails
If you choose to contact Wordcork by email, your email address and the contents of your message are processed only to read, respond to, and keep a reasonable record of the support request.
For users in regions with privacy laws requiring a legal basis, including the European Economic Area, United Kingdom, Switzerland, and countries in South America with applicable privacy laws, the legal basis is Wordcork's legitimate interest in providing support and responding to user requests, or consent where applicable.
Children
Chemistry Box is intended as an educational tool and does not require an account or collect personal information from anyone, including children. Children should use the app with parent, guardian, or teacher supervision appropriate for their age and local rules.
Deleting Local Data
You can delete local app data by uninstalling Chemistry Box, clearing app storage in Android settings, or clearing browser/site data for the app page.
Because Chemistry Box stores gameplay data locally on your device and does not send it to Wordcork, Wordcork cannot access, export, or delete that local gameplay data for you.
Regional Privacy Rights
If you are in a region with privacy rights, including U.S. states or territories with applicable privacy laws, countries in South America with applicable privacy laws, the European Economic Area, United Kingdom, or Switzerland, and you contact Wordcork by email, you may request access, correction, deletion, restriction, objection, portability, or other rights available under your local law for personal data contained in that support correspondence.
You may also lodge a complaint with your local data protection authority where available. To make a request, email wordcork@gmail.com.
Changes
Wordcork may update this policy from time to time. Material changes will be reflected in the effective date above and, where appropriate, in the in-app legal notice version.
