Kex terms of use

Published: 30 September 2026. These terms describe use of the Kex desktop application, its optional modules and the services at kex.eu.com. Kex is developed and operated by Krzywy. Contact the developer through the contact form or Telegram.

Kex is developed and operated as a private project based in Germany by Kacper Kreft (Krzywy). For privacy questions and requests, you can email admin@kex.eu.com without a Telegram account. This contact also covers data held by Kex services, not only files stored on your computer.

Updated 28 October 2026: clarified the operator, computer identifiers, reCAPTCHA, privacy requests and the limits of existing deletion procedures. The Google data sharing and Limited Use commitments remain unchanged.

1. What Kex provides

Kex is an independent Windows client for communicating through supported third-party services and using optional features such as media playback and email. Available functions depend on the installed version, enabled modules, provider authorization and the external service. A feature described as planned or under preparation is not a promise that it is already available.

Updated 12 October 2026: public betas, starting with 0.16, and private test builds have separate release lists. The download page identifies the published public version. Private test access does not guarantee a particular release schedule. Beta software may contain defects. Update notifications offer a choice to download or postpone; they do not promise immediate delivery when offline.

Kex is not an official product of Google, Microsoft, Telegram or the other services it connects to. Their names identify integrations and do not imply endorsement.

2. Accounts and authorization

Connect only accounts and servers you own or are authorized to use. Follow the applicable provider's terms, access restrictions and age requirements. You are responsible for choosing the correct recipients and for protecting your device, vault password and account access. Do not share login codes or authorization tokens with support.

For Gmail and Microsoft mail, authorization takes place on the provider's sign-in page. Kex uses the permissions you grant to provide its mail functions. You may revoke access using the provider's account controls. An organization's administrator may restrict access or require approval.

3. Permitted use and content

You may install and use the official Kex distribution for its intended functions. Separate licenses supplied with third-party components continue to apply. These terms do not grant rights to other people's messages, recordings, streams or software.

Do not use Kex for unlawful access, fraud, harassment, spam, distributing malicious software or interfering with other people's accounts or services. Obtain the necessary rights and permissions before sharing content or recording others. You retain your rights to your own content; using Kex does not transfer ownership of your messages or email to the developer.

4. Privacy and optional services

The privacy policy explains data processing, local storage, authorization tokens, diagnostics, backups and user choices. Sending support files or using cloud backup is optional. Review attachments before sending them. Removing an account from Kex does not itself delete that account or its messages at the external provider, nor does it remove earlier backups.

5. External services and costs

External providers control their own availability, account decisions, limits and prices. Internet access and third-party subscriptions may incur charges under your agreements with those providers. These terms do not authorize Kex to charge a payment card or enroll you in a paid service. Any paid Kex offering would need clearly stated pricing and a separate affirmative order.

6. Updates, reliability and support

Kex and its modules receive fixes and may change as external services evolve. Software errors, maintenance and provider outages can interrupt a feature. No specific uninterrupted availability or support response time is promised here. Keep appropriate backups of important data and check delivery with the provider if a send operation has an uncertain outcome.

Report problems or complaints using the contact options above, describing the affected version, the issue and the outcome you seek. Include a reply address if you want a response. Do not include passwords or a complete account vault.

7. Stopping use and service restrictions

You can stop using Kex, disconnect accounts, revoke provider permissions and remove local files at any time. Contact the developer about deleting data held by Kex services, as described in the privacy policy. To protect users or comply with law, access to Kex-operated online services may be restricted where necessary in response to abuse or a security incident. You may contact the developer to ask for a review. External providers make their own access decisions.

8. Your rights and changes to these terms

Nothing in these terms excludes liability or limits consumer rights or other rights that cannot lawfully be excluded or limited. Applicable law determines responsibility for faults and any remedies. These terms do not require you to give up access to courts or statutory complaint procedures.

Revisions will be published at this address with a new date and a description of material changes. Where the law requires notice or consent, publication alone does not replace it. Changes do not retroactively remove accrued rights.
