Terms of service

Working draft. These terms are a draft prepared for legal review. Final language will be reviewed by counsel before launch and may change. Last updated: May 2026.

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 privacy hub for supported social media and email services. OSL Protected mode adds end-to-end encryption to supported messages exchanged between approved users who both have OSL.

OSL is not affiliated with, endorsed by, or operated by the services it connects to. Use of each connected service remains subject to that provider's terms.

Account and purchase terms #

OSL offers two tiers:

  • Free tier: protected text on supported connectors, with no message limit.
  • Pro tier: the intended price is $5 for one month of Pro. Checkout is paused until one-month redemption and expiry are implemented. Pro is an early-access purchase. Today it unlocks early access to new privacy tools as they reach the beta channel — not the v1 feature set, which is still being finished. This is not a subscription: nothing renews automatically, we do not store your payment details, no OSL account is required, and there is nothing to cancel.
  • Processing credits: Planned and not currently offered for sale. If they are introduced, they will be bought separately from Pro, will never renew, and will not be required for encryption to work.

Purchase checkout is currently paused. The intended card, Bitcoin and Monero offer is one payment for one month, with no recurring subscription or stored payment method. Automatic one-month expiry and return to Free are not implemented yet. Refund requests for any earlier transaction are handled according to applicable law and the payment provider's rules.

Acceptable use #

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

  • Each connected provider's terms still apply. We cannot represent or guarantee a provider's actions, including potential account restrictions.
  • OSL is a tool for private communication, not a shield for illegal conduct.
  • The source licenses allow inspection, modification, and redistribution under their stated terms. They do not grant permission to misuse OSL infrastructure, payment services, or another person's account.

Disclaimers #

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

  • Whether a connected provider will tolerate a particular OSL integration 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 desktop client and backend repository are published under Apache 2.0. The website repository is published under AGPL 3.0. Each repository includes the controlling license text.

Those source licenses do not grant rights to impersonate OSL Privacy or suggest that a fork is an official OSL release. Use a different name and branding for an independent fork.

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 revoke access to OSL operated services if you violate these terms. If we do, we will explain why when legally permitted.

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. Material changes will be posted on the website. Continued use of OSL after changes constitutes acceptance.
