If you encounter any issues while using the app, or have any suggestions and feedback, feel free to contact us. We'll get back to you as soon as possible.
Here are answers to some common questions. If you don't find what you're looking for, feel free to contact us.
No. All features (export, import, data processing) work completely locally and don't require an internet connection. Your privacy is fully protected.
Absolutely not. All contact data reading, processing, export, and import operations happen entirely on your device. We don't have servers to store your data, and we can never access your contacts.
Three export formats are supported: Excel (.xlsx), CSV (.csv), and VCF (vCard). You can choose the format that suits your needs. Excel offers the richest features, while VCF has the best compatibility. Contact avatars can be exported as ZIP files.
Four import formats are supported: Excel (.xlsx), CSV (.csv), VCF (vCard), and ZIP (with data + avatars). The app auto-detects file formats and smartly maps fields.
We offer 2 import modes:
1. Clear then write: Clear existing contacts before importing — ideal for cross-device migration, ensuring exported contacts are fully restored
2. Merge with existing: Compare each contact, skip if it already exists (full-field match), add if new — ideal for appending contacts
Import only adds new contacts and never modifies existing contact data, so there's no risk of silent data loss.
Cross-platform migration is very simple:
1. On the source device, export an Excel file using "Full mode"
2. Transfer the Excel file to the target device (via AirDrop, email, cloud drive, etc.)
3. On the target device, open this app and import the Excel file using "Clear then write" mode
The app automatically handles field differences between platforms to ensure complete data migration. "Clear then write" mode ensures the exact number of contacts exported are restored — no more, no less.
Currently supports 4 languages: Chinese (Simplified), English, Japanese, and Spanish. The app automatically follows the system language setting, or you can manually switch in Settings.
Exported files can be saved to:
• The app's folder in the Files app
• iCloud Drive
• Other third-party cloud drive apps (if supported)
You can also share directly to other apps via the share function.
You can download a standard template file from the Settings or Import page in the app. The template includes all supported fields — just fill in the data according to the template to import.
Yes. The app automatically follows the system's dark/light mode setting. You can also manually select light or dark mode in app settings.
If import fails, try the following:
1. Make sure the file format is correct (.xlsx, .csv, .vcf, or .zip)
2. Check if the file is corrupted, try re-exporting or re-downloading
3. Confirm the file contains valid contact data
4. Make sure you've granted contacts access permission
If the problem persists, please send the file and error screenshot to hcyanli@gmail.com and we'll help you resolve it as soon as possible.
Yes. When exporting, you can:
