Strike Vault™ for Android
Everything you need to buy, install, and start using Strike Vault™ on your Android phone or tablet. No technical experience required — just follow the steps.
Buy a LicensePart 1 · How to Buy
Choose your plan
Go to strikevault.app/buy/android. Pick the plan that fits you: Individual (1 device), Team (2 devices per user), or Organization (3 devices per licensee).
Enter your email and pay
Type the email address where you want your license sent, then continue to the secure Stripe checkout. Enter your card details and confirm. Your payment is processed safely by Stripe — we never see your card number.
Get your license code by email
Within a minute of paying, you'll receive an email from support@strikevault.us containing your license code (it looks like SV-XXXX-XXXX-XXXX). Keep this email — the app verifies the code against the same email address during registration.
Part 2 · How to Install
Download the app file
Open the email and tap the Download Strike Vault link. This downloads the app installer (an .apk file) to your phone. When your browser asks, tap Download to confirm.
Allow installs from your browser (one time)
Because Strike Vault is delivered directly to you (not through the Play Store), Android asks permission the first time. When prompted, tap Settings, turn on Allow from this source, then tap back. You only do this once.
Open and install
Tap the downloaded file (find it in your Downloads or the notification bar). Tap Install, wait a few seconds, then tap Open.
Part 3 · How to Activate & Use
Open Strike Vault and verify your license
Launch the app. On first run, enter the license code from your email (SV-XXXX-XXXX-XXXX) and the same email address used for purchase, then tap Verify license.
Confirm username and display name
After the license matches, Strike Vault fills in the holder, email, and plan details. Confirm or enter your username, choose the display name other users will see, then continue registration.
Set up your secure unlock
Follow the prompts to enable biometric unlock (fingerprint or face). This protects your data so only you can open it.
You're ready
That's it. You can now create and open secure Data Capsules, message contacts, and use the map — all protected with post-quantum encryption, even with no internet connection.
Common Questions
How many devices can I use one license on?
Individual = 1 device, Team = 2 devices per named user, Organization = 3 devices per named licensee. Each device redeems the same code until the seats are used up.
I didn't get my license email.
Check your spam/junk folder for a message from support@strikevault.us. If it's not there after a few minutes, email support@strikevault.us with your purchase email and we'll resend it.
Is it safe to install an app this way?
Yes. Strike Vault is delivered directly to licensed customers and is digitally signed by CyCrypt, Inc. The "allow from this source" step is a standard Android prompt for any app installed outside the Play Store.
Can I move my license to a new phone?
Yes. Install the app on the new device and register with the same license code and email. If all seats are in use, contact support to release an old device.
What about the Desktop and iOS apps?
Desktop (Windows/macOS/Linux) releases June 30, 2026 and is available for pre-order now. iOS is coming in Q4 2026. See strikevault.app.
