NameMemory

NameMemory is a memory support app designed to help you remember people's names. It uses scientifically-based spaced repetition learning (SM-2 algorithm) to support efficient memory retention.

To add a person, follow these steps:

1. Tap the "New Registration" button on the home screen
2. Enter the person's name
3. Take a photo or select from gallery
4. Add memo or tags if needed
5. Tap the "Save" button

There are two ways to add photos:

• Take with camera: Tap "Camera" button to take directly
• Select from gallery: Tap "Gallery" button to choose existing photos

Photos are automatically compressed and optimized to save storage space.

Tags are used to categorize and organize people:

• Add tags: Enter tags in the person edit screen
• Filter by tags: Tap tag chips on the home screen
• Recommended tags: "Business", "Friends", "Family", "Colleagues", etc.

Using tags allows you to display only people in specific categories.

NameMemory has multiple search and filtering features:

• Search box: Search by name or memo content
• Quick filters: Filter by "All", "Need Review", "Business"
• Tag filters: Display only people with specific tags

Combining these features allows you to quickly find the person you're looking for.

3. Modify information and tap "Save"

To delete:

1. Tap "Delete" button on the edit screen
2. Select "Delete" in the confirmation dialog

About face detection and privacy:

• On-device processing: Face detection runs locally using Google ML Kit; photos and face data are not sent to servers
• Model download: On first use, ML models may be downloaded to your device from Google; your photos are not uploaded
• Permissions: Camera and storage are used only for capture and reading images; you can use avatars or register without photos

Follow these steps to restore purchases:

2. Tap Restore purchases
3. Confirm you’re signed in with the same Google/Apple account used for purchase
4. Restart the app after restore completes

If paid features are locked after updating:

2. Ensure the same store account is signed in
3. Restart the app
4. Update Google Play/App Store app if restore fails
5. Contact support if the issue persists

When you don't have photos or prioritize privacy, you can use the avatar feature:

1. Select "Create Avatar" on the person add screen
2. Choose hairstyle, clothing, accessories, etc.
3. Tap "Generate" button
4. Save your preferred avatar

Privacy considerations when using avatar feature:

• External service: Accesses Avataaars.io (US)
• Data sent: IP address, avatar parameters
• Alternative: Manual photo upload available

You can register people without photos:

1. Select "Skip Photo" on the person add screen
2. Create avatar or add photo later
3. Complete registration with name and memo only

You can add photos or avatars later.

The SM-2 algorithm is a scientifically-based spaced repetition learning system developed by Dr. Piotr Wozniak in 1987:

This algorithm scientifically supports efficient memory retention.

How the review system operates:

1. Automatic scheduling: App calculates optimal review timing
2. Notifications: Push notification when review time arrives
3. Quiz format: Choose correct answer from options
4. Evaluation: Automatically evaluates review results
5. Adjustment: Adjust next review date based on evaluation

Continuing reviews improves memory retention rates.

You can adjust review schedule in these ways:

• Notification time: Change daily notification time in settings
• Automatic evaluation: Intervals automatically adjust based on review accuracy rate
• Manual review: Start review anytime

Business mode is a feature that can be used when you want to record more detailed information:

• Company/Organization name: Record affiliated organization
• Relationship: Relationships like friends, colleagues, boss, clients
• Meeting place: Places like meetings, exhibitions, networking events, schools, clubs
• Keywords: Features or topics you want to remember

Enabling business mode displays more detailed information during reviews, enabling memory support in various scenes.

To create data backup, follow these steps:
