EMAIL SUPPORT

Still need a hand?

Tell us what happened and what you expected. We can help diagnose an app issue, but we cannot view your vault or retrieve passcodes and backup passwords.

Include the essentials

Your iPhone model and iOS version
HiCalculator app version
A short description of what you expected and what happened
Steps we can follow to reproduce the issue
A screenshot with private information removed, if useful

Never send secrets

Vault or decoy passcodes
Backup passwords or encryption keys
Security answers
Private photos, passwords, or other vault content

Purchases and billing

For Restore Purchases, tell us which product you bought and what the app currently shows. Billing, cancellations, and refunds are managed by Apple through your App Store account. For a refund request, use Apple’s Report a Problem service.

Data recovery limits

We do not hold a master key or a copy of your vault. A forgotten passcode or backup password cannot be reset or recovered by support. For a device move, verify a restore before erasing your old device.
