Terms of Use

1. Acceptance of these terms

These Terms of Use ("Terms") form a binding agreement between you and f0x.it LLC ("we", "us", "our"), the operator of Muxr. They govern your use of the App, the Site, and Muxr Push, and they serve as the end-user licence agreement for the App.

By downloading, installing, or using the App, or by using the Site or Muxr Push, you accept these Terms. If you do not accept them, do not install or use the App and do not use Muxr Push.

You must be old enough to enter into a binding contract where you live in order to use Muxr.

2. Definitions

3. Licence to the app

The App is licensed to you, not sold. Subject to these Terms and to your payment of any applicable fees, we grant you a personal, non-exclusive, non-transferable, revocable licence to install and use the App on devices that you own or control, for your own use.

On Apple devices, that licence is limited to Apple-branded products you own or control and is subject to the Usage Rules in the Apple Media Services Terms and Conditions, including the Family Sharing provisions. On Android devices, the equivalent Google Play terms apply.

Except as permitted by these Terms or by mandatory law, you may not:

• copy, redistribute, sell, rent, lease, sublicense, or otherwise make the App available to third parties;
• reverse engineer, decompile, or disassemble the App, or attempt to derive its source code;
• modify the App, or create derivative works of it;
• remove or obscure any proprietary notices; or
• circumvent purchase, licensing, subscription, or rate-limiting controls.

We retain all right, title, and interest in the App, the Site, and the Muxr name and marks. Nothing in these Terms transfers ownership of anything to you.

4. Open-source components

The server side of Muxr is separate, open-source software. muxr-core — including muxrd, muxrctl, and muxr-notify — is published under the MIT licence, and your use of it is governed by that licence rather than by section 3 of these Terms. Where the MIT licence and these Terms conflict in respect of muxr-core, the MIT licence prevails.

muxr-core, like all software provided under the MIT licence, is provided "as is", without warranty of any kind. The App may also include third-party open-source components, each under its own licence.

5. Your server, your responsibility

Muxr is a self-hosted system: you provide and operate the server that the App connects to. Accordingly, you are solely responsible for:

• installing, configuring, updating, and securing your muxrd server and the machine it runs on, including its network exposure and TLS configuration;
• the bearer tokens and certificates you mint, and for keeping them confidential — anyone holding a token can act on your server within its scope;
• everything that is executed, transmitted, or destroyed through the terminal sessions you connect to, whether by you or by anyone using your credentials;
• having authorisation to access the systems you connect to, and complying with the policies and laws that apply to them; and
• your own backups. Muxr is a control surface for your terminal, not a backup service.

We have no access to your server, cannot recover your tokens or data, and cannot undo commands run through a session. A terminal executes what it is given — including destructive commands.

6. Purchases and subscriptions

All purchases are made and billed through your Apple App Store or Google Play account, under that store's terms. We do not process or store payment details.

Pro unlock (one-time purchase)

Pro is a non-consumable in-app purchase: you pay once and the paid features are unlocked for the store account that bought it. It can be restored on your devices through the store's normal restore-purchases mechanism. It does not renew, and there is nothing to cancel.

Muxr Push (auto-renewable subscription)

Access to the hosted Muxr Push relay is sold as an auto-renewable subscription. The following applies:

• The subscription title, duration, and price are shown in the App before you confirm the purchase. Payment is charged to your store account when you confirm.
• The subscription renews automatically for the same period at the then-current price unless you cancel it at least 24 hours before the end of the current period. Your store account is charged for the renewal within the 24 hours before the current period ends.
• You manage and cancel the subscription in your store account settings — Settings › your name › Subscriptions on iOS, or the Subscriptions section of the Google Play app on Android. We cannot cancel it for you.
• Deleting the App does not cancel the subscription.
• Where a free trial or introductory offer is made available, any unused portion is forfeited when you purchase the subscription, to the extent the store's rules so provide.
• Refunds are handled by Apple or Google under their own policies; we are not able to issue store refunds directly.
• Prices may change. Changes apply only to future billing periods, and the store will notify you and seek any consent required before a changed price is charged.

7. Acceptable use

You agree not to use the App, the Site, or Muxr Push:

• for any unlawful purpose, or to access any system you are not authorised to access;
• to send notifications that are unlawful, deceptive, harassing, or that constitute spam or malware distribution;
• to overload, flood, or otherwise abuse the hosted relay or the Site, to evade rate limits or registration limits, or to register devices you do not control;
• to resell, redistribute, or provide relay capacity to third parties as a service; or
• to interfere with, probe, or attempt to defeat the security of our infrastructure.

We may rate-limit, suspend, or terminate access to the hosted relay if we reasonably believe it is being used in breach of this section. Self-hosting remains available in all cases.

8. App Store and Google Play terms

The App is distributed through the Apple App Store and Google Play. The following terms are required by, and apply in respect of, those stores.

• Acknowledgement. These Terms are concluded between you and f0x.it LLC only, and not with Apple Inc. or Google LLC. f0x.it LLC alone is responsible for the App and its content.
• Scope of licence. The licence granted in section 3 is non-transferable and limited to use of the App on Apple-branded products that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions; the corresponding Google Play terms apply to Android devices.
• Maintenance and support. f0x.it LLC is solely responsible for providing any maintenance and support for the App. Apple and Google have no obligation whatsoever to furnish any maintenance or support services for it.
• Warranty. To the maximum extent permitted by applicable law, Apple has no warranty obligation with respect to the App. If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the App to you; any other claims, losses, liabilities, damages, costs, or expenses attributable to a failure to conform to a warranty are the sole responsibility of f0x.it LLC.
• Product claims. f0x.it LLC, and not Apple or Google, is responsible for addressing any claims relating to the App or your possession or use of it, including product-liability claims, claims that the App fails to conform to any applicable legal or regulatory requirement, and claims arising under consumer-protection, privacy, or similar legislation.
• Intellectual property. If a third party claims that the App or your possession and use of it infringes that third party's intellectual property rights, f0x.it LLC is solely responsible for the investigation, defence, settlement, and discharge of that claim.
• Legal compliance. You represent and warrant that you are not located in a country subject to a U.S. Government embargo or designated by the U.S. Government as a "terrorist supporting" country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
• Third-party terms. You must comply with any applicable third-party terms of agreement when using the App — including the App Store or Google Play terms and your wireless data-plan terms.
• Third-party beneficiary. Apple and its subsidiaries are third-party beneficiaries of these Terms and, upon your acceptance of them, have the right (and are deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary. Google has equivalent rights in respect of the App as distributed through Google Play, to the extent the Google Play terms so provide.
• Contact. Questions, complaints, and claims relating to the App should be directed to f0x.it LLC at [email protected].

9. Privacy

Our handling of data is described in the Privacy Policy, which forms part of these Terms. In short: there are no accounts, no analytics, and no advertising; your terminal traffic flows only between your device and your own server; and the hosted relay stores only the minimal registration record described there.

10. Disclaimer of warranties

The App, the Site, and Muxr Push are provided "as is" and "as available", without warranties of any kind. To the maximum extent permitted by applicable law, we disclaim all warranties, express or implied, including the implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement.

We do not warrant that the App, the Site, or Muxr Push will be uninterrupted, timely, secure, or error-free, or that defects will be corrected. Notification delivery is best-effort: it depends on Google's Firebase Cloud Messaging and any platform push infrastructure downstream of it, on your network, and on your device's own settings, and notifications may be delayed, deduplicated, or not delivered at all. Do not rely on Muxr Push for emergencies, medical or safety-critical alerting, or any situation where a missed or delayed notification could cause harm or loss.

Some jurisdictions do not allow the exclusion of certain warranties, so some of these exclusions may not apply to you; in that case they apply to the fullest extent permitted.

11. Limitation of liability

To the maximum extent permitted by applicable law, f0x.it LLC will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, nor for any loss of profits, revenue, goodwill, or data, business interruption, or the cost of substitute services, arising out of or in connection with the App, the Site, Muxr Push, or these Terms — including any damage caused by commands executed through a terminal session, by an undelivered or delayed notification, or by the loss or compromise of a token — even if we have been advised of the possibility of such damages.

To the maximum extent permitted by applicable law, our total aggregate liability arising out of or relating to these Terms is limited to the greater of (a) the amounts you actually paid us or the applicable store for the App, Pro, or the Muxr Push subscription in the twelve months preceding the event giving rise to the claim, and (b) USD 50.

You agree to indemnify and hold f0x.it LLC harmless from claims, losses, and expenses arising out of your use of the App, your operation of your own server, the systems you connect to, or your breach of these Terms.

Some jurisdictions do not allow the limitation or exclusion of liability for certain damages, so some of the above may not apply to you. Nothing in these Terms limits liability that cannot lawfully be limited, including liability for fraud, death, or personal injury caused by negligence.

12. Termination

These Terms apply until terminated. You may terminate them at any time by ceasing to use the App and the Site, deleting the App from your devices, and — if you subscribe to Muxr Push — cancelling the subscription in your store account settings.

We may suspend or terminate your access to the hosted relay, or terminate this licence, if you materially breach these Terms. On termination, the licence granted in section 3 ends and you must stop using and delete the App. Termination does not entitle you to a refund of amounts already paid, except where required by law or granted by the store under its own policies.

Sections that by their nature should survive — including sections 4, 5, and 10 through 15 — survive termination.

13. General

• Changes to these Terms. We may update these Terms. The revised version will be posted on this page with an updated effective date, and — where the change is material — announced in the App or on the Site. Continued use after the effective date means you accept the revised Terms; for subscriptions, changes apply from the next renewal period.
• Severability. If any provision is held unenforceable, it is modified to the minimum extent necessary, or severed, and the remaining provisions stay in full force.
• No waiver. Our failure to enforce any provision is not a waiver of it.
• Assignment. You may not assign or transfer these Terms without our written consent. We may assign them in connection with a merger, acquisition, or sale of assets.
• Entire agreement. These Terms and the Privacy Policy are the entire agreement between you and f0x.it LLC regarding the App, the Site, and Muxr Push, and supersede any prior understandings — except that the MIT licence governs muxr-core, and the applicable store's terms govern your relationship with Apple or Google.

14. Governing law

These Terms are governed by the laws of [JURISDICTION — to be confirmed with counsel], without regard to its conflict-of-laws rules. The courts of [JURISDICTION — to be confirmed with counsel] will have exclusive jurisdiction over any dispute arising out of or relating to these Terms.

Nothing in this section deprives you of the protection of any mandatory consumer-law provisions of the country in which you reside, or of your right to bring proceedings in the courts of that country where the law gives you that right.
