Terms of Service

Last updated: March 2026

1. Agreement to Terms

These Terms of Service ("Terms") constitute a legally binding agreement between you ("User", "you") and Oynux ("Company", "we", "us", "our") governing your access to and use of the oynux.com website and all associated services, including email, cloud storage, photos, notes, calendar, and contacts (collectively, the "Service").

By creating an account, accessing, or using any part of the Service, you acknowledge that you have read, understood, and agree to be bound by these Terms and our Privacy Policy. If you do not agree to these Terms, you must not use the Service.

2. Description of Service

Oynux provides a suite of end-to-end encrypted digital services, including but not limited to encrypted email, cloud file storage, photo management, note-taking, calendar, and contact management. All user content is encrypted on the client device prior to transmission to our servers using OpenPGP encryption (AES-256). Communication is facilitated via standard protocols including IMAP, SMTP, and JMAP.

The Service is designed on a zero-knowledge architecture, meaning the Company does not possess the technical means to decrypt, access, or view your stored content.

3. Account eligibility and responsibilities

  • You must be at least 16 years of age to create an account
  • You must provide accurate and complete registration information
  • You are solely responsible for maintaining the confidentiality and security of your account credentials, password, and recovery phrase
  • You may not sell, transfer, license, or assign your account to any other party
  • Each individual is limited to one free account. Creating multiple free accounts to circumvent service limitations constitutes a violation of these Terms
  • You are responsible for all activity that occurs under your account, whether or not authorized by you

4. Acceptable use

You agree to use the Service only for lawful purposes and in accordance with these Terms. The following activities are strictly prohibited:

  • Sending spam, phishing messages, or unsolicited bulk communications
  • Distributing malware, viruses, ransomware, or other malicious software
  • Accessing, storing, or distributing child sexual abuse material (CSAM) or any content depicting the exploitation of minors
  • Harassing, threatening, defaming, or intimidating any person
  • Infringing upon the intellectual property rights, privacy, or other rights of third parties
  • Attempting to circumvent, disable, or interfere with security features, rate limits, or access controls
  • Using automated systems, bots, or scrapers to access the Service without prior written authorization
  • Engaging in fraudulent activity, including the use of stolen payment credentials
  • Any activity that violates applicable local, national, or international law

Any account found to be in violation of these restrictions is subject to immediate suspension or permanent termination at our sole discretion, without prior notice or refund.

5. Subscription, payment, and refunds

Free accounts are available without payment and are subject to the usage limits of the Free tier. Paid subscription plans are billed monthly in advance at the rates displayed on our pricing page. All prices are in Canadian Dollars (CAD) unless otherwise specified. Applicable taxes may be added depending on your jurisdiction.

Payments are processed by Stripe, Inc. Subscriptions renew automatically at the then-current rate unless cancelled before the next billing date. You may cancel your subscription at any time through your account settings.

Refund policy: We offer a 30-day money-back guarantee for initial paid subscription purchases. Refunds are prorated based on unused days. After the initial 30-day period, no refunds will be issued for any reason, including unused portions of a billing cycle. Refund requests may only be submitted once per user. Refunds are issued at the Company's discretion.

Delinquent accounts: If a paid subscription lapses due to non-payment, your account will be downgraded to the Free tier. If your stored data exceeds Free tier limits, certain functionality (such as sending emails, uploading files, or creating new content) may be restricted until you reduce your usage or reactivate a paid plan. Your existing data will not be immediately deleted, giving you reasonable time to export it.

6. Your content and intellectual property

You retain full ownership of all content you create, upload, store, or transmit through the Service. Because your content is end-to-end encrypted, we cannot access, review, moderate, or verify it. You are solely responsible for the legality and appropriateness of all content associated with your account.

You grant us a limited, non-exclusive, royalty-free license to store and transmit your encrypted data solely for the purpose of operating and delivering the Service. This license terminates upon deletion of your account. We claim no ownership interest in your content.

7. Password, recovery, and data loss

Due to the encrypted nature of the Service, you acknowledge that the Company has no ability or obligation to recover your data if you lose or forget your password and recovery phrase. There is no password reset mechanism. Your 12-word BIP-39 recovery phrase is the sole means of account recovery. We strongly recommend storing it securely offline in multiple physical locations.

Upon account deletion — whether initiated by you, triggered by inactivity (see Section 8), or resulting from Terms of Service enforcement — all associated data is permanently and irreversibly erased from our servers within 30 days. This includes all emails, files, photos, notes, calendar events, and contacts. This deletion cannot be undone.

You acknowledge and accept that the Company shall not be held liable for any loss of data resulting from your failure to maintain your credentials, from account termination, from service interruptions, from security incidents, or from any other cause whatsoever.

8. Inactive accounts

Free accounts that have been inactive for a period of 3 consecutive months may be scheduled for deletion. Inactivity is defined as no login to any Oynux service (web, desktop, or mobile) and no use of any Oynux product during that period.

Before deletion, we will attempt to notify the account holder at their registered email address at 30 days, 15 days, and 7 days prior to the scheduled deletion date. Paid subscription accounts are exempt from this policy and remain active regardless of usage for the duration of the paid subscription.

9. Service availability

We endeavor to maintain high availability of the Service but do not guarantee uninterrupted, timely, or error-free operation. The Service may be temporarily unavailable due to scheduled maintenance, software updates, infrastructure upgrades, or circumstances beyond our reasonable control (including but not limited to natural disasters, power outages, network failures, denial-of-service attacks, or acts of government).

We will make reasonable efforts to provide advance notice of planned maintenance. We shall not be liable for any damages, losses, or consequences arising from service interruptions or unavailability.

10. Disclaimer of warranties

THE SERVICE IS PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS, WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.

The Company does not warrant or represent that:

  • The Service will meet your specific requirements or expectations
  • The Service will be uninterrupted, timely, secure, or error-free
  • The results obtained from the use of the Service will be accurate or reliable
  • Any defects or errors in the Service will be corrected
  • The Service will be free from viruses, malware, or other harmful components

The Company does not make any warranty about the reliability of the Service or the security of user data, despite best efforts. Any material downloaded, uploaded, or otherwise obtained through the use of the Service is done at your own discretion and risk. You are solely responsible for any damage to your devices or loss of data that results from the use of the Service.

11. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL THE COMPANY, ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, OR AFFILIATES BE LIABLE TO YOU OR ANY THIRD PARTY FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, including but not limited to:

  • Loss of data, revenue, profits, or business opportunities
  • Loss of goodwill or reputation
  • Cost of procurement of substitute services
  • Unauthorized access to, alteration of, or destruction of your data
  • Any interruption of service or inability to access the Service

regardless of the cause of action or the theory of liability (whether in contract, tort, strict liability, or otherwise), and even if the Company has been advised of the possibility of such damages.

The Company's total cumulative liability to you for all claims arising out of or related to the Service shall not exceed the greater of (a) one hundred Canadian dollars (CAD $100) or (b) the aggregate amount paid by you to the Company for the Service during the twelve (12) months immediately preceding the event giving rise to the claim.

12. Indemnification

You agree to indemnify, defend, and hold harmless the Company and its officers, directors, employees, agents, and affiliates from and against any and all claims, demands, actions, damages, losses, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or related to:

  • Your use of or access to the Service
  • Your violation of these Terms
  • Your violation of any rights of any third party
  • Any content you store, transmit, or make available through the Service

13. Intellectual property

The Oynux name, logo, trademarks, website design, and all associated visual and textual elements are the exclusive property of the Company. You may not reproduce, duplicate, copy, modify, sell, or exploit any portion of the Service or its branding without express written permission from the Company.

14. Modifications to these Terms

The Company reserves the right to modify, amend, or replace these Terms at any time. If a revision is material, we will make reasonable efforts to provide at least 30 days' notice prior to the new terms taking effect, by sending an email to the address associated with your account.

Your continued use of the Service after the effective date of the revised Terms constitutes your acceptance of and agreement to the changes. If you do not agree to the revised Terms, you must discontinue use of the Service and delete your account.

In the event of any conflict between translated versions of these Terms, the English version shall prevail.

15. Governing law and dispute resolution

These Terms shall be governed by and construed in accordance with the laws of the Province of Québec and the federal laws of Canada applicable therein, without regard to conflict of law principles.

Any dispute, claim, or controversy arising out of or relating to these Terms or the Service shall first be attempted to be resolved through good-faith negotiation. If negotiation is unsuccessful within 30 days, the dispute shall be submitted to the exclusive jurisdiction of the courts of the judicial district of Montréal, Québec, Canada.

You agree to waive any right to participate in a class action lawsuit or class-wide arbitration against the Company.

16. Severability

If any provision of these Terms is held to be invalid, illegal, or unenforceable by a court of competent jurisdiction, such provision shall be modified to the minimum extent necessary to make it enforceable, and the remaining provisions shall continue in full force and effect.

17. Entire agreement

These Terms, together with the Privacy Policy and any other policies referenced herein, constitute the entire agreement between you and the Company regarding the use of the Service, and supersede all prior and contemporaneous understandings, agreements, representations, and warranties, whether written or oral.

The failure of the Company to exercise or enforce any right or provision of these Terms shall not operate as a waiver of such right or provision.
