Need a hand?

Email is our main support channel. Write to the address above and we'll answer in the order messages arrive.

It helps if you include your device (for example iPhone 15 Pro), your iOS version, a short description of the problem and, if you can, a screenshot.

Weekday messages usually get an answer within 1 to 2 business days. Weekends and holidays can take longer. If it's urgent, write URGENT in the subject line and we'll look at it first.

Subscriptions bought through the App Store are managed by Apple. To ask for a refund, go to reportaproblem.apple.com, find the purchase and send your request to Apple.

To cancel, open Settings on your iPhone, tap your name, then Subscriptions > Prevena.

For anything outside Apple's refund rules, email us and we'll see what we can do together.

Not seeing your sleep or steps? Open the Health app, tap your profile picture, then Apps > Prevena, and turn on the data you want to share. Apple doesn't tell apps which data you chose not to share, so Prevena can only say it sees no data.

To delete only your Apple Health data, go to Profile > Apple Health, tap Disconnect and choose Disconnect and delete. It's removed from our live database immediately.

The Apple Watch app works with Prevena on your paired iPhone. If an attack you logged on the watch hasn't shown up on your phone yet, it's waiting for a connection and will sync on its own.

To delete your account and all your data, go to Profile > Delete My Account. Deleting your account in the app removes your data from our live database within 24 hours and from backups within 14 days.

If you can't reach the app anymore (for example, you lost your phone), email us from any address and we'll help.

For the details of what we collect, how we store it and your rights, read our Privacy Policy.
