Questions about testing

What do I need to become a KEYLUN tester?

An Android phone and a Google account. Use the same account in all three steps: in the testers group, on the Google Play testing page and in Google Play on your phone.

Is testing KEYLUN free?

Yes. Closed testing is free: you install KEYLUN from Google Play like any other app and get updates earlier. We don't promise paid perks for taking part — just early access and a say in how the app develops.

Can I leave the test?

Yes, at any time. Open the testing page play.google.com/apps/testing/com.keylune.vault and leave the program, or leave the testers group. You can then uninstall the app or wait for the public version.

What data does the developer see?

The developer can see the email address of the Google account you used to join the group and the test (it is shown in Google Play Console), plus any feedback you send. How the app handles data on your phone is described in its privacy policy.

Why can't I find or install KEYLUN on Google Play?

During closed testing the app is available only to test participants. Make sure the group, the testing page and Google Play on your phone all use the same Google account, and give it a little time — access sometimes takes a while.

Can I lose data in the test version?

It is a test version, so bugs are possible. For important data make a backup or export if the app supports it.

03Data, price, languages

Your vault lives only on your phone

Vault entries are stored only in the app's private storage on your device, and only in encrypted form. There is no sign-up, no cloud sync, no ads, no analytics and no network requests of its own, and Android's system backup doesn't include the vault. We can't see your data, so we can't recover your vault or a forgotten backup passphrase.

Frequently asked questions

Write to us
Is it safe to store passwords on your phone?

Safer than notes or paper, as long as the vault is encrypted and your phone has a screen lock. KEYLUN encrypts the vault with AES-256-GCM, and the key sits in Android Keystore, working only on an unlocked phone after you confirm. No password manager can promise full protection on a rooted or compromised device.

Where should I store passwords if not in the cloud?

In a local password manager. KEYLUN keeps the vault on your phone only — no account, no sync and no servers of ours. The contents of your vault never travel over the network.

Does KEYLUN work offline?

Yes. The vault, the generator and unlocking all work fully offline. The network is used only by Google Play, to buy KEYLUN Pro or support the developer.

Do I need a master password?

There's no separate master password. The vault opens with whatever unlocks your phone: biometrics, PIN, pattern or password. You can also set a backup passphrase of at least 12 characters as a fallback.

Does KEYLUN autofill passwords in other apps?

No, KEYLUN has no autofill service. You can view a password in SAFE mode or copy it briefly in COPY mode — KEYLUN then tries to clear the clipboard after 15 seconds.

How do I move my passwords to a new phone?

Export the vault to an encrypted .klx file and import it on the new device — this is a KEYLUN Pro feature. The file is protected by an export password of at least 10 characters. Android's system backup doesn't carry the vault over.

What happens if I reset my phone or turn off the screen lock?

The vault key is tied to your phone's security. If that becomes unavailable, the vault opens only with your backup passphrase or from an export file. Without them your passwords can't be recovered — we have no access to your data or keys.

How do I create a strong password?

Open a new entry and use the generator: choose a length from 12 to 48 characters and the character sets — upper and lower case, digits, symbols. Use a different password for every site; KEYLUN remembers them all for you.
