About

This extension only works with the KEEPSER® app available for free on Google Play. You must also have at least one NFC KEEPSER® device. It is a highly secure card that works for life contactless via a phone with NFC technology.

It makes it possible to secure end-to-end from the device the use of encrypted sensitive data contained in the device called "Keeps" via a computer web browser. 

It works with any desktop or laptop using a Chromium-compatible web browser and other operating systems. Computers and NFC phones paired with devices should only be on the same local network. The latter is also encrypted by the solution.

The device is also a "Cold Wallet". It allows its user to securely manage and share, from the device, the private keys and public addresses of cryptocurrencies, as well as recovery phrases for private keys, BIP39 standard, "Seed Phrases".

Advantageously, it performs autofill and automatic connection on any computer and / or laptop present in the same local network. They just need to be paired with at least one phone. Thus, the user can connect a guest user, for example, without the latter physically needing to own a device.

It leaves no digital trace in computers. In fact, a computer can have multiple users with their own devices.

Everything is outsourced to the device, which fits in your pocket.

PORTABILITY OF GREEN TECHNOLOGIES FOR SECURITY AND CYBERSECURITY
It does not collect or store any personal data. Its use is completely anonymized. You will not be asked for any information about yourself and/or the Device.

It can work without being connected to a cloud server or the internet.

DATA SOVEREIGNTY
Only you can access your data. Neither we nor anyone else can access the secrets you store encrypted in the device.
