Frequently Asked Questions

Does Utilio require an internet connection?

No. Utilio is designed as an offline-first app, and most features work without internet access. The only feature that needs network access is currency conversion, which downloads the latest rates when online and caches them locally.

Will my data be uploaded to the cloud?

No. Utilio does not collect, store, or transmit personal data. All data stays inside your device’s app sandbox. There are no analytics trackers, no third-party SDKs, and no ad networks. See our Privacy Policy for more details.

How secure are encrypted notes?

Secure notes use AES-256-GCM encryption. The encryption key is stored in the device Keychain with ThisDeviceOnly access, so it is never synced to iCloud. You can also set a separate note password for extra protection.

Will my data remain after deleting the app?

No. Deleting Utilio permanently removes all local data, including encrypted notes, keys, history, and preferences. This action cannot be undone.

How can I reorder tools on the home screen?

Open the home screen and tap the Reorder button in the top-right corner. Then drag and drop the tool cards to your preferred order. Tap Done to save it. You can also add tools to favorites from the detail view.

Is the decibel meter accurate?

The decibel meter uses your device microphone to estimate environmental noise levels. Because it is not calibrated with professional equipment, readings are approximate and intended for reference only.

How do I use the color picker?

Open the Color Picker, choose a photo from your library, and tap the area you want to sample. Utilio will show the full color information, including HEX, RGB, HSL, HSV, and CMYK, and you can copy it with one tap.

How do I change or reset the note password?

Go to Settings > Security > Note Password to set a new password, change an existing one, or clear it. Password hashes are stored locally and cannot be reversed.

Which iOS versions are supported?

Utilio supports iOS 15.0 and later. We recommend using the latest iOS version for the best experience.

🔧 Troubleshooting

Camera is not working

Go to Settings > Utilio > Camera and enable camera access. If it still doesn’t work, close and reopen the app.

No sound from the decibel meter

Make sure microphone access is allowed in Settings > Utilio > Microphone.

Compass is inaccurate

Enable location access in Settings > Utilio > Location. If the reading is off, wave the device in a figure-8 motion to calibrate it.

Currency rates are not updating

Make sure your device is online. Rates update when there is a connection and then remain available offline from the cache.

Forgotten note password

For security reasons, note passwords cannot be recovered. You can clear the password in Settings > Security > Note Password after verifying the old one. If verification fails, deleting the app is the only reset option.

The app crashes

Make sure you are using the latest version. If the issue persists, contact us by email and describe the steps to reproduce it.
