Privacy Policy

Moodropic · Last updated: August 2026

1. What is Moodropic

Moodropic is a free, local-only Progressive Web App (PWA) for tracking supplement intake, sleep, mood and performance, and for spotting statistical patterns between them. It is developed and maintained independently by Feym Luna.

2. Data collection

Moodropic collects no personal data of any kind. Specifically:

• No name, email address, or account is required or collected.
• No supplement, health, mood, or diary data is ever transmitted to any server.
• Moodropic collects no usage analytics and sends no crash or diagnostic reports. Separately from the app, Google Play and the web server that delivers it produce their own figures, such as install counts, request counts and crashes reported by the Android system. Those come from the platforms, not from anything the app sends.
• No cookies are used.
• No advertising networks or third-party SDKs are embedded.

3. Local storage

All data you enter (supplement modules, daily intake, sleep and ratings, mood drops, context tags, notes and app settings) is stored exclusively in your browser's IndexedDB, a standard browser feature that keeps data on your device only. Moodropic contains no code that transmits this data. A copy leaves your device only through an export you start yourself, and then only to wherever you send it.

Backups are created only when you explicitly tap "Export backup" and are handed to you as a file via your device's share or download dialog. You decide where that file goes.

You can delete all stored data at any time from within the app (Data → Delete all data) or by clearing your browser/app data through your device settings. Deletion is immediate and irreversible.

4. Notifications

The optional daily reminder is scheduled entirely on your device using the browser's background-sync mechanism. No push server is involved and no data is exchanged with any third party to deliver it. It can be switched off at any time (Data → Daily Reminder).

5. External connections

The app loads its own static code from its hosting domain and caches it for offline use. Fonts ship with the app, no external font or CDN requests are made. Beyond those files, the app requests nothing from the network. Two optional links point outside it, and both open only when you explicitly tap them:

• Buy Me a Coffee (buymeacoffee.com/feymluna), the support link at the bottom of the System tab. It is entirely voluntary and governed by Buy Me a Coffee's own privacy policy.
• Your email app, from the contact link under System → About. Writing to us is your choice, and the message goes through your own mail provider, not through Moodropic.

6. Health disclaimer

Moodropic is provided for informational purposes only. It does not constitute medical advice, diagnosis, or treatment. Supplement descriptions and benefit summaries in the built-in library are educational, mechanism-based summaries of published research; individual physiology varies significantly.

Patterns reported by the app's correlation engine are statistical associations, not causal or medical conclusions. Small personal datasets can produce spurious correlations.

Do not rely solely on this app to make health decisions. Consult a qualified healthcare professional or pharmacist before starting, stopping, or combining supplements, especially alongside prescription medication, pregnancy, or existing conditions.

7. Children

This app is intended for users aged 18 and older. We do not knowingly collect any data from children under 13. Since no data is collected from anyone, there is nothing to collect from minors either.

8. Changes to this policy

If this privacy policy changes, the updated version will be published with a revised "Last updated" date. Since no data is collected, changes are unlikely to affect users materially.
