Terms of service

The agreement between you and OSL Privacy.

Acceptance of terms #

By downloading, installing, or using OSL Privacy ("OSL", "the service"), you agree to these terms. If you don't agree, don't use the service.

Description of service #

OSL is a desktop application that wraps the Discord client and adds end-to-end encryption to messages exchanged between users who both have OSL installed and have whitelisted each other.

OSL is not affiliated with, endorsed by, or operated by Discord Inc. Use of OSL is at your own risk with respect to Discord's terms of service.

Account and subscription terms #

OSL offers two tiers:

• Free tier — unlimited encrypted text messaging at no cost. Free users can receive but not send encrypted attachments.
• Paid tier — $5/month or $50/year — unlocks encrypted attachment sending and early access to new features through the beta channel. Subscriptions auto-renew at the end of each billing period unless cancelled.

You may cancel your subscription at any time. No refunds are provided for partial billing periods. Cancellation takes effect at the end of the current period.

Acceptable use #

You agree not to use OSL for any illegal activity. You acknowledge that:

• Discord's terms of service still apply to your use of Discord through OSL. We are not affiliated with Discord and cannot represent or guarantee anything about Discord's actions, including potential account suspensions.
• OSL is a tool for private communication, not a shield for illegal conduct.
• You will not attempt to reverse-engineer, decompile, or extract our license-validation system. The cryptographic primitives are published for audit; the rest of OSL — including the Discord integration and licensing infrastructure — is not open source.

Disclaimers #

OSL is provided "AS IS" without warranty of any kind. We make no representations or warranties about:

• Whether Discord will tolerate OSL or take action against accounts using it.
• Whether future cryptographic attacks may compromise OSL's protections. We use widely-trusted, peer-reviewed algorithms, but cryptography evolves and we make no guarantee against future attacks.
• Whether the service will be uninterrupted or error-free.
• Whether OSL is suitable for your specific use case, including high-risk threat models. See our threat model.

Limitation of liability #

To the maximum extent permitted by law, OSL Privacy and its operators are not liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of OSL — including loss of data, loss of access, account suspension, or any other harm caused by use of the service.

Our total liability for any claim is limited to the amount you paid us in the 12 months preceding the claim, or $50, whichever is greater.

Intellectual property #

The cryptographic primitives are published for public audit at /audit. The rest of OSL is proprietary.

The OSL Privacy name, brand, and marketing materials are not covered by the Apache-2.0 license. Don't ship a fork called "OSL Privacy" — fork the code and use a different name.

Your messages and the data you create using OSL remain entirely yours. We have no copy of them, no claim on them, and no ability to access them.

Termination #

You may stop using OSL at any time. Uninstall the application and your local data stays on your device.

We may terminate or suspend your paid subscription if you violate these terms. If we do, we'll explain why.

Governing law #

These terms are governed by the laws of California, United States, without regard to conflict-of-law principles.

Changes to these terms #

We may update these terms over time. If we make material changes, we'll notify subscribers by email and post a notice on the website. Continued use of OSL after changes constitutes acceptance.
