The service
Plexus Mail is a local-first mail service provided by Unsync Software. It provides passkey-based access and relays separately encrypted packages between registered devices. The service may change as security, compatibility, and operational requirements evolve.
Who may use Plexus
You must be at least 13 years old and legally permitted to use the service where you live. If you are below the age of legal majority, you must have permission from a parent or legal guardian. Organizations are responsible for authorizing their users and complying with laws that apply to their deployment.
Your account and recovery
- Choose a handle you are permitted to use and do not impersonate another person or organization.
- Protect your passkeys, devices, recovery codes, and exported backups. Plexus cannot recover a lost local mailbox or forgotten backup passphrase.
- Tell us promptly if you believe an account or device has been compromised.
- An account may be removed after 365 days without a successful passkey unlock, as described in the Privacy Policy.
Your content
You retain rights in the messages and other content you create. You give Plexus only the limited permission needed to encrypt, route, store temporarily, deliver, and—when you deliberately submit a safety report—review the selected reported content. You are responsible for your content and for having the right to send it.
Acceptable use and enforcement
You must follow the Acceptable Use Policy. We may rate-limit, restrict, suspend, or terminate access when reasonably necessary to protect users, investigate abuse, comply with law, or maintain service security. We will consider context and proportionality where practical.
Availability and updates
We work to keep Plexus available and secure, but do not promise uninterrupted or error-free operation. Maintenance, outages, provider failures, security incidents, or changes to browsers and operating systems may affect the service. Install updates when they become available because older versions may lose compatibility or security support.
No warranty
To the maximum extent permitted by law, Plexus is provided “as is” and “as available,” without warranties of uninterrupted availability, fitness for a particular purpose, or preservation of device-local data. Nothing in these terms excludes a warranty or consumer right that cannot lawfully be excluded.
Limitation of liability
To the maximum extent permitted by law, Plexus and its operator are not liable for indirect, incidental, special, consequential, or punitive loss, or for loss caused by a user’s device, credentials, recipients, third-party services, or failure to maintain backups. Nothing limits liability where doing so would be unlawful, including liability for fraud or willful misconduct.
Ending use
You may stop using Plexus at any time and delete local application data through your device or browser. Contact us to request deletion of eligible server-held account information. Some limited records may remain where required for security, legal compliance, retired-handle protection, or backup rotation.
Governing law and contact
These terms do not take away mandatory consumer protections that apply where you live. Before starting a formal dispute, please contact [email protected] so we can try to resolve it.
