Frequently Asked Questions

How do I change the language?

Open Settings inside Oxyn and tap "Language". You can pick English, Turkish, Spanish, Portuguese, or Arabic. By default the app follows your device language.

How do I switch between dark and light theme?

Settings → Appearance → Theme. Choose Light, Dark, or System Default.

Why does Oxyn ask for photo library access?

Photo access is only used to scan for duplicate and large photos so you can free up storage. Your photos never leave your device.

How do I cancel my Oxyn Plus subscription?

Open the iPhone Settings app → tap your name at the top → Subscriptions → find Oxyn Plus → Cancel Subscription. Your subscription will remain active until the end of the current period.

My battery health reading looks different from iPhone settings — why?

Oxyn's battery health is an estimate based on charge cycles and patterns we can measure from the app. The official maximum capacity in iPhone Settings is calculated by iOS with hardware-level data. Both are useful, but the iOS value is the authoritative one.

How can I report a bug or request a feature?

Email us at support@oxynapp.net with a short description and (if possible) a screenshot. We read every message.

Troubleshooting

Optimization is stuck or not finishing

Close Oxyn (swipe up from the bottom of the home screen, then swipe Oxyn off the App Switcher), reopen, and try again. If the issue continues, contact support.

App crashes on launch

Make sure you are on iOS 16.0 or later. If the issue persists, please email us with your iPhone model and iOS version.
