Privacy Policy
This Privacy Policy explains how MindFeast handles information in the MindFeast Android app, including the app listed on Google Play as MindFeast: Lock Screen.
MindFeast is designed for parent-managed family devices. The app helps parents create and show learning slides, questions, art, reflection prompts, and gratitude prompts during ordinary device use.
MindFeast does not use advertising, does not sell personal information, and does not provide a MindFeast cloud account service.
Device Security
MindFeast is an educational lock screen experience. It does not replace Android's built-in device lock, password, PIN, pattern, fingerprint, face unlock, encryption, or other security features. Parents should use Android's system security settings to protect the device and the information stored on it.

Information Stored on the Device
MindFeast stores app information locally on the device so the app can work as a parent-managed learning tool. This may include:
- Parent-created slides, prompts, questions, answers, hints, accepted answers, informational text, images, and audio.
- Starter slides and installed slide packs.
- Which slides are active for a child or device.
- Basic completion history.
- Essay responses and gratitude journal responses.
- App settings, including lock screen settings, remote trigger settings, sync settings, and slide creation preferences.
- A local admin PIN hash, if the parent creates an admin PIN.
- Optional credentials or secrets entered by the parent, such as a Gemini API key, SMB/local folder sync credentials, and a remote trigger token.
- Local purchase entitlement state for installed slide packs.
This information is used to provide the app's core features. MindFeast does not operate its own server to receive or store this information.
Information Shared with Third Parties
MindFeast only sends information outside the device when a parent uses a feature that requires it or when Google Play services are used.
Google Play Billing
MindFeast uses Google Play Billing for app purchases and one-time slide pack purchases. Google processes payment information and purchase transactions. MindFeast receives purchase status information from Google Play so the app can unlock purchased content. MindFeast does not receive full credit card or bank account information.
Gemini AI Features
MindFeast includes optional Gemini AI slide creation features. These features are off unless a parent provides a Gemini API key and chooses to create or regenerate slide content with Gemini.
When a parent uses Gemini features, MindFeast sends the parent-provided API key and slide creation request to Google's Gemini API. The request may include the parent's prompt, style instructions, selected slide type, and any image URL the parent provides for context. If Gemini image generation is used, MindFeast sends an image prompt to Gemini and receives generated image data.
Parents should not include private child information in Gemini prompts unless they are comfortable sending that information to Google under the terms and privacy practices that apply to the Gemini API and the parent-provided API key.
Parent-Provided Media URLs
If a parent enters an image URL or audio URL, MindFeast downloads that file from the URL. The website or server hosting that URL may receive normal network request information, such as the device's IP address.
Local Folder or SMB Sync
MindFeast can optionally sync slides with a parent-provided shared folder on a home computer or local network file server. When this feature is configured, MindFeast connects to the server information entered by the parent and may upload or download slide files, images, audio, and slide metadata.
MindFeast does not control the parent-provided computer, file server, network share, or any backups of that shared folder.
Remote Trigger
MindFeast includes an optional remote trigger feature. If enabled by a parent, the app runs a small local web control interface on the device so another device on the same local network can trigger or manage slides. The remote trigger uses a token in the local URL and only accepts local or link-local network connections.
MindFeast does not send remote trigger activity to a MindFeast server.
Advertising and Tracking
MindFeast does not show ads.
MindFeast does not include third-party advertising SDKs.
MindFeast does not sell personal information.
MindFeast does not use information for cross-app or cross-site tracking.
Children and Family Use
MindFeast is intended to be managed by parents. Children may interact with slides, answer questions, write essay responses, or respond to gratitude prompts. These responses are stored locally in the app so parents can review them.
Parents are responsible for choosing the content shown to their children and for deciding whether to use optional features that send information outside the device, such as Gemini AI, media URL downloads, or SMB/local folder sync.
Permissions
MindFeast uses Android permissions to provide app functionality, including:
- Display over other apps, foreground service, notifications, and boot startup permissions so MindFeast can show selected learning slides during ordinary device use.
- Internet access for optional Gemini AI features, optional media downloads, Google Play Billing, optional local network sync, and optional remote trigger features.
MindFeast uses these permissions for app functionality, not for advertising or tracking.
Security
MindFeast is designed to keep family content local by default.
The local admin PIN is stored as a one-way hash, not as plain text. Sensitive settings such as SMB passwords, Gemini API keys, and remote trigger tokens are stored locally in encrypted form where supported by Android. MindFeast excludes its settings DataStore from Android cloud backup and device-transfer extraction rules.
No method of storage or transmission is perfectly secure. Parents should protect the device, choose an appropriate admin PIN, restrict any Gemini API key they create, and secure any local network file shares they configure.
Android Backup and Device Transfer
Android and Google services may provide app backup, restore, or device-transfer features depending on the user's device settings and Google account configuration. MindFeast excludes its settings DataStore from Android cloud backup and device transfer, but other app data may be handled by Android backup or transfer mechanisms according to Android and Google settings.
Data Retention and Deletion
MindFeast keeps local app data on the device until it is deleted by the parent, removed by app features, cleared through Android system settings, or removed by uninstalling the app.
Parents can delete essay responses and gratitude journal entries in the app. Parents can also remove app data by using Android's app storage controls or by uninstalling MindFeast.
If a parent syncs slides to a shared folder, copies in that shared folder must be managed or deleted separately by the parent. If a parent sends prompts or other information to Gemini, that information is handled by Google under the terms and privacy practices that apply to the Gemini API and the parent-provided API key.
MindFeast does not provide cloud accounts, so there is no MindFeast account to delete.
Changes to This Policy
MindFeast may update this Privacy Policy as the app changes. If the policy changes, the updated version will be posted at:
