Features

Control over a message, even after sending

For every message you set when and how many times the recipient may open it.

Message validity

Set the period in which the message can be opened, for example only on the day of a meeting. Outside it, the message will not open even though it is in the recipient’s mailbox.

Open limit

Set how many times the recipient may open the message. Once the limit is reached, it is destroyed on their side automatically.

Destroy after reading

After opening, the message closes and is destroyed after the time you set, for example ten seconds. Ideal for passwords and credentials.

No forwarding

The recipient cannot forward the message from Talkey or quote it in a reply. The content stays with them only.

Message recall

Sent a message by mistake, or circumstances changed? Invalidate it even after delivery and it will no longer open for the recipient.

Applies to your copy too

Apply the same rules to your own copy in Sent. It then behaves exactly like the recipient’s, including destruction.

TLP classification

Every message carries a confidentiality level under the international Traffic Light Protocol standard. The recipient sees at a glance who they may share it with.

RED

For the recipient only. Not shared further without the sender’s consent.

AMBER+STRICT

Recipient’s organisation only, strictly need-to-know.

AMBER

Recipient’s organisation and its partners, need-to-know.

GREEN

Recipient’s community, not via publicly accessible channels.

CLEAR

No restrictions on sharing.

Security

How Talkey protects message content

Encryption happens on your device, decryption only at the recipient’s. Nobody else has access to the keys or content, not even TALKEY a.s.

Encryption: Double: symmetric AES-256-GCM and asymmetric ECDH 384.
Signature: Every message is signed with ECDSA-384.
End-to-end: The message is encrypted on the sender’s device and decrypted only on the recipient’s device.
Algorithms: Meet the requirements of the Czech National Cyber and Information Security Agency (NÚKIB).
Keys: Created and kept on your device, in a database protected by the application password. There is no master key.
Supplier access: TALKEY a.s. has no access to your keys, application password or message content.
Key backup: An encrypted backup is created on first launch. Use it to restore keys or move them to a new device.
Transport: Text and attachments travel in a Talkey.mtm container attached to an ordinary e-mail. Mail servers see only the covering note.
Sender verification: Every message is signed. The recipient sees that the signature is valid and the fingerprint of the key used.
Usage data: The application does not collect or record any data about how you use it.
Supplier: Developed and operated in the Czech Republic. TALKEY a.s. holds NBÚ security clearance.

FAQ

Frequently asked questions

Does the recipient need a paid licence?

No. Only the sender needs a licence. The recipient downloads Talkey free of charge, creates a key on first launch and opens the message.

Do we have to change our mail server or addresses?

No. Talkey sits on top of your existing mail. It sends through your own mailbox — either connecting to it directly or handing the message to your mail program.

What does the mail provider see?

An ordinary e-mail with a covering note and one attachment. Neither the body nor the attachments are in it — they are inside the container, and the provider has no key.

Where are the keys stored?

On your device, in a database protected by your application password. You create a key backup on first launch — without it you will not reach old messages after changing computers.

What if I lose my phone or computer?

You restore the keys from the backup. You can also transfer them to a new device straight from an application you are already signed in to.

Is Talkey a mail client?

No. It does not replace Outlook or Apple Mail and it does not fetch your mail. It is the application in which you write an encrypted message and in which it opens when one arrives.

How does this relate to DORA, NIS2 and the Czech Cybersecurity Act?

Encryption alone satisfies no obligation. The rules for who may send what and through which channel are covered by the secure communication policy by riscare; Talkey is the tool that carries them out.
