Note, Calculator, Timer — How can we help?
All your notes, calculator history, and timer presets are stored locally on your device. NCT does not upload any data to external servers. Your data stays private and under your control.
Notes are stored in your device's app documents directory. On iOS, they are included in iCloud backups if enabled. On Android, they are included in your device backup. We recommend keeping regular device backups to protect your data.
NCT is available in English, Spanish, and French. The app follows your device's language setting automatically.
Go to the Timer tab, tap the duration chips to set your desired time, then press Start. You can customize the alarm sound and vibration mode in Settings > Timer Settings.
Make sure notifications are enabled for NCT in your device settings. On Android, you may also need to grant the Exact Alarm permission. Go to Settings > About in the app to check your notification permission status.
Yes. In the Notes tab, you can create folders, move notes between folders, and rename folders using the file explorer on the left side of the screen.
The ANS button inserts the result of your most recent calculation into the current expression. This lets you chain calculations without retyping previous results.
