Privacy Policy

This policy covers the Unlike Authenticator app for Android, published by Adamanture Private Limited, Kanchipuram, Tamil Nadu, India. Its registered office and contact details are on the Contact page.

In short: the app collects no data and cannot reach the internet, so it sends nothing you add to it to us or to anyone else. This website is covered separately, by the Adamanture Privacy Policy.

The app stores the accounts you add: for each, the service name, your account name and its secret key. It also stores its own settings, such as how soon it locks. All of it sits in one encrypted file in the app’s private storage on your phone.

The file is encrypted with AES-256-GCM. A key derived from your password with Argon2id protects the key that opens it. The app stores nothing off your phone.

None of these exist in the app:

• Network accessNo internet permission
• AccountsNo sign-up and no sign-in
• AnalyticsNone
• Crash reportingNone
• AdvertisingNone
• Third-party SDKsNone that collect data

The camera is used only to scan a QR code, when you add an account or import from Google Authenticator. The picture is read on your phone, is not saved and does not leave it. The app keeps only the account details the code contains, in the encrypted vault.

Android asks for camera permission the first time you scan. The app works without it: you can paste a link, type a key in by hand or import a file.

Biometric unlock is optional and stays off until you turn it on. Android does the fingerprint or face check and tells the app only whether it passed. The app never sees, stores or sends fingerprint or face data.

If you turn it on, a key held in Android’s Keystore opens the vault after the check. The key stays on your phone. Your password always still works.

The app’s data is excluded from Android and Google cloud backup and from device-to-device transfer, so a new phone starts empty. To move your accounts, make an export: a file you create, protect with a password you choose, and keep wherever you like.

An export is yours to look after. If you save it to a cloud service or copy it into another app, that service or app handles it under its own terms. A plain-text export is not encrypted and shows every secret key, so the app asks you to confirm before it makes one.

When you copy a code, the app marks it sensitive and clears the clipboard after 45 seconds, if the code is still there. If the app is in the background at that moment, it clears the clipboard when you return to it.

The app blocks screenshots and screen recording by default. You can allow them in Settings, after a warning.

Everything the app holds is on your phone. Uninstalling the app, or clearing its storage in Android’s settings, deletes the vault and every account in it. Adamanture keeps no copy, so there is nothing for us to delete.

Exports you made are separate files. Delete them yourself, wherever you saved them.

Unlike Authenticator is a general-purpose security tool and is not directed at children. It collects no data from anyone, so it collects none from children.

If we change this policy, the new version replaces this page and carries its own effective date. The app has no internet access, so it cannot tell you about a change; check the date at the top of this page. This version takes effect on 25 October 2026.
