Terms of Service

1. Who We Are

Qaxa is operated by Qaxa Labs s. r. o., a company registered in the Czech Republic under ID No. 232 43 279, with its registered office at Křižíkova 213/44, 186 00 Prague 8 – Karlín, Czech Republic.

Qaxa is made available internationally, subject to applicable laws and regulations.

2. Eligibility and Accounts

You must be at least 16 years old, or the minimum age required to validly consent to digital services in your jurisdiction, to use Qaxa.

To create an account, you must provide a valid email address and set a password.

Your email address is used for authentication, service-related notifications, and communications regarding your account.

Workspace content, including messages, files, notes, and tasks, is designed to be end-to-end encrypted. Your email address, screen name, and billing information, are stored unencrypted where necessary for operational purposes, such as authentication, account recovery, invitations, payment processing, and billing receipts.

You are responsible for maintaining the confidentiality of your login credentials and for all activities that occur under your account.

3. Plans

Qaxa may offer different service plans, including free and paid plans.

The Guest Plan is a free plan and may provide limited access to selected Qaxa features.

The Solo Plan is a paid plan intended for individual users and may include additional features, storage, or usage limits beyond those available under the Guest Plan.

The Firm Plan is a paid plan intended for teams, firms, or other organizations and may include additional features, administrative controls, storage, or multi-user functionality.

The features, limits, availability, and pricing of each plan may change from time to time. All plans remain subject to these Terms.

4. Payments, Renewals, and Refunds

Payments may be processed through third-party payment providers, including Stripe for credit card payments.

Credit card payments are offered as recurring subscriptions only.

By purchasing a paid plan, you authorize Qaxa and its payment processors to charge your selected payment method for the applicable fees and taxes and, in the case of credit card subscriptions, any recurring renewal charges corresponding to your selected plan and billing cycle.

You may cancel a recurring credit card subscription at any time through your account settings. Unless otherwise stated, cancellation will take effect at the end of the current billing period, and you will retain access to the paid plan until that period ends.

Except where required by applicable law, fees paid for credit card subscriptions are also non-refundable. Qaxa may, in its sole discretion, grant refunds for credit card payments in individual cases.

If you downgrade from a paid plan to the Guest Plan, or otherwise change your plan, certain features, limits, or storage capacity may change or become unavailable.

5. Privacy and Security

Qaxa is designed with privacy and encryption in mind.

Workspace content, including messages, files, tasks, and notes, is intended to be end-to-end encrypted. Your email address, screen name, and billing data are not end-to-end encrypted where operationally necessary.

Qaxa does not use your content for advertising purposes.

Qaxa may use privacy-respecting, self-hosted analytics tools to collect limited service usage information in aggregate form. Qaxa does not use third-party advertising analytics services such as Google Analytics.

For more information, please review our Privacy Policy and, where applicable, our Data Processing Agreement (DPA).

6. Acceptable Use

You agree not to:

• violate any applicable law or regulation;
• use Qaxa to send spam or abusive, fraudulent, or unlawful content;
• upload, transmit, or share content that is illegal or infringes the rights of others;
• attempt to bypass, disable, probe, or interfere with encryption, authentication, security features, or access controls;
• interfere with or disrupt the operation of Qaxa or other users’ use of the service.

We may investigate suspected violations and may suspend or terminate accounts that violate these Terms or create risk for Qaxa, its users, or third parties.

7. Content and Intellectual Property

As between you and Qaxa, you retain ownership of the content you upload, submit, store, or share through Qaxa.

You grant Qaxa a limited, non-exclusive license to host, process, encrypt, transmit, and display your content only as necessary to operate, maintain, secure, and provide the service to you.

Qaxa and its software, interface, branding, logos, and related materials are owned by Qaxa Labs s. r. o. or its licensors and are protected by applicable intellectual property laws. These Terms do not grant you any right to use Qaxa’s trademarks, branding, or proprietary materials except as necessary for your permitted use of the service.

8. Open Source Software

Qaxa may include, use, or rely on third-party open source software components in connection with the operation and delivery of the service.

These components are licensed under their respective open source licenses, which may include, among others, the GNU Lesser General Public License (LGPL), the MIT License, the Apache License, the BSD License, and other applicable open source license terms.

A list of open source components used by Qaxa, together with applicable copyright notices, attribution information, and license terms where required, will be made available in Qaxa’s open source notices, third-party notices, technical documentation, or another appropriate location designated by Qaxa.

The current list of such components includes, without limitation, the following:

• openpgp.js — licensed under the GNU Lesser General Public License, version 3.0 or later (LGPL-3.0-or-later)

Qaxa may update this list from time to time as components are added, removed, replaced, or updated.

Where required by an applicable open source license, Qaxa will preserve relevant notices and provide access to the corresponding license text and other required attribution information.

Nothing in these Terms limits your rights under any applicable open source license with respect to third-party software distributed with or used as part of Qaxa.

9. Data Storage and Availability

Qaxa seeks to provide reliable access to the service, but we do not guarantee uninterrupted or error-free operation.

We may perform maintenance, updates, upgrades, or changes that temporarily affect availability.

Because encrypted systems depend on account credentials, keys, and client-side access, certain encrypted content may become permanently inaccessible if required credentials, keys, or recovery materials are lost.

You are responsible for maintaining your own backups or exports of important data where appropriate.

10. Termination

You may stop using Qaxa at any time and may delete your account.

We may suspend or terminate your access to Qaxa, with or without notice, if:

• you violate these Terms;
• you misuse or abuse the service;
• your use creates security, legal, or operational risk for Qaxa or others; or
• we are required to do so by law.

Upon termination, your right to use Qaxa will end. We may delete, disable, or render inaccessible associated data, subject to applicable law and our internal retention practices.

11. Warranty Disclaimer

To the maximum extent permitted by applicable law, Qaxa is provided “as is” and “as available.”

Qaxa disclaims all warranties, whether express, implied, statutory, or otherwise, including any implied warranties of merchantability, fitness for a particular purpose, title, non-infringement, availability, or that the service will be uninterrupted, secure, or error-free.

Your use of Qaxa is at your own risk.

12. Limitation of Liability

To the maximum extent permitted by applicable law, Qaxa Labs s. r. o., and its directors, officers, employees, contractors, affiliates, and partners, will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenues, goodwill, use, business opportunity, or data.

To the maximum extent permitted by applicable law, Qaxa’s total aggregate liability arising out of or relating to the service or these Terms will not exceed the greater of:

• EUR 50, or
• the amount you paid to Qaxa for the service during the 12 months preceding the event giving rise to the claim.

Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law.

13. Dispute Resolution, Arbitration, and Class Action Waiver

If you have a dispute with Qaxa, you agree to first contact us and attempt to resolve the dispute informally.

If the dispute cannot be resolved informally, then, to the extent permitted by applicable law, any dispute, controversy, or claim arising out of or relating to these Terms or the use of Qaxa shall be finally resolved by binding arbitration.

Unless otherwise required by applicable law, arbitration shall be conducted by the Arbitration Court attached to the Economic Chamber of the Czech Republic and Agricultural Chamber of the Czech Republic, or another neutral arbitration body agreed by the parties.

The arbitration shall be conducted in English or Czech. The seat or place of arbitration shall be determined in accordance with the applicable arbitration rules, unless the parties agree otherwise.

To the extent permitted by applicable law, you and Qaxa agree that each may bring claims only in an individual capacity and not as a plaintiff or class member in any purported class, collective, consolidated, or representative proceeding.

Nothing in this section limits any mandatory rights you may have under applicable consumer protection law, including mandatory rights under Czech or EU law where applicable.

This section survives termination of these Terms.

14. Governing Law

These Terms are governed by the laws of the Czech Republic, excluding its conflict of law principles, except to the extent that mandatory consumer protection laws of your country of residence apply and cannot be contractually excluded.

15. Changes to These Terms

We may update these Terms from time to time.

If we make material changes, we may provide notice by email, through the service, or by other reasonable means before the updated Terms become effective.

Your continued use of Qaxa after the effective date of the updated Terms constitutes your acceptance of the revised Terms.
