Privacy Policy

Overview

NexKey is an authenticator application for iOS, Android and macOS. It generates one-time passwords on your device. This policy describes what data NexKey processes, why, and what choices you have.

Two things are true of NexKey by design, and the rest of this policy follows from them:

• One-time codes are generated on your device, not on a server.
• If you turn on synchronization, your authenticator data is encrypted on your device before it leaves it.

Data we process

We process the smallest amount of data needed to run the service:

• Account data — if you create a NexKey account for synchronization, the identifier you register with and the credentials needed to authenticate you.
• Encrypted vault data — if synchronization is enabled, the ciphertext of your authenticator vault.
• Device records — the trusted devices you have enrolled, so you can review and revoke them.
• Diagnostics — if you opt in, technical information about crashes and errors.
• Website data — standard server request logs and, when enabled, Google Analytics usage data for this website.

Authentication data

Your authenticator secrets — the shared keys that produce your one-time codes — are stored in platform secure storage on your device: Keychain on Apple platforms and the Android Keystore on Android.

We do not receive readable authenticator secrets, and we do not receive the one-time codes NexKey generates.

This website does not generate one-time codes, does not accept authenticator secrets, and stores no authentication data in your browser.

Device information

When you enroll a device for synchronization we record what is needed to manage that relationship: a device identifier, a device name you can recognise, the platform, and the time it last synchronized. This exists so that you can review your trusted devices and revoke any of them.

Diagnostics

Diagnostic reporting is optional and off unless you enable it. When enabled, it is limited to technical information about failures.

Diagnostics never include authenticator secrets, generated one-time codes, the names of the services you hold accounts with, or the contents of your vault.

Encrypted synchronization

Synchronization is optional.

When it is enabled, your authenticator data is encrypted on your device before upload. Our backend stores and transfers that ciphertext. Decryption happens on your trusted devices.

You can disable synchronization at any time, which keeps your authenticator data local to each device.

Website

This site is a product and marketing website. The production configuration enables Google Analytics to measure visits and website usage. Google Analytics uses cookies and processes information about page visits, browser and device characteristics, and interactions with the website.

The website does not send authenticator secrets or generated one-time codes to Google Analytics.

If you contact support through this website, we process the name, email address and message you send in order to answer you.

Retention

To be confirmed in legal review. Retention periods must be stated per data category — account data, encrypted vault data, device records, diagnostics, support correspondence and server logs — before publication.

Your rights

Depending on where you live, you may have rights to access, correct, export or delete your personal data, and to object to or restrict certain processing.

To be confirmed in legal review: the exact rights, the response window and the supervisory authority to which complaints may be directed.

Changes to this policy

If we make material changes to this policy we will update the effective date above and, where appropriate, notify you in the app.
