Troubleshooting

The App Won't Start

Desktop

1. Quit once and restart
2. End any leftover processes in Activity Monitor / Task Manager, then restart
3. Reinstall the app (your data is retained)
4. If it still does not resolve: send the logs from ~/Library/Application Support/niyase/logs (macOS) or %APPDATA%\niyase\logs (Windows) to support@niyase.com

Mobile

1. Fully quit the app and restart
2. Update the OS to the latest version
3. Reinstall the app (caution: local data will be erased, so back it up first)

Can't Log In

Symptom	What to do
Password not accepted	Send a password reset email
Email not arriving	Check your spam folder; allow the domain @niyase.com
Two-factor code not accepted	Check your device's clock sync / use a backup code
Passkey not responding	Check your OS biometric settings / log in with another method, then re-register the passkey

Sync Isn't Working

1. Click the sync status in the app bar to view details
2. Check your network connection
3. Space settings → Sync → "Retry sync"
4. Check whether the relevant space's plan has changed to FREE (FREE cannot sync)
5. If it still does not resolve, check the error records in the audit log screen and send them to support

My Data Disappeared

• First, don't panic — open the same space on another device to check (if cloud sync is ON)
• You can identify deleted records from the audit log
• The local DB may be recoverable, so stop the app and contact support@niyase.com (do not perform any operation that overwrites the DB)

Printing / PDF Looks Broken

• PDF: Update to the latest version, then regenerate
• Printing: Check with the preview function → instead of browser printing, we recommend the in-app "Save as PDF → Print"
