Terms & Conditions

Last updated: September 22, 2026

These Terms & Conditions (also referred to as the "Terms", "Agreement", or "EULA") are a legal agreement between you ("you" or "User") and Binary Work, LLC ("we", "us", "our" or "Company"), governing your access to and use of the Rubber macOS application (the "App") and related services, websites, and content (collectively, the "Service"). By downloading, installing, accessing, or using the App or Service you agree to be bound by these Terms. If you do not agree, do not use the App.

1. License Grant

Subject to your compliance with these Terms and payment of any applicable fees, Binary Work, LLC grants you a limited, non-exclusive, non-transferable, non-sublicensable license to use the App on devices you own or control, strictly in accordance with the functionality provided. The license is granted on a per-user basis and not as an unlimited or enterprise license, unless you obtain a separate written agreement from us.

The scope of the license depends on the edition you use. The free edition is licensed for personal, non-commercial use only. Commercial use requires Rubber Pro — an active subscription or a lifetime purchase — as described in section 2.

A Rubber Pro purchase covers one person: the user of the Apple ID that made it. An organization whose people use the App commercially needs Rubber Pro for each of them; contact us if you need several licenses at once.

2. Editions, Pricing & Subscriptions

Free Tier

Rubber is available as a free edition, licensed for personal, non-commercial use. It includes the Viewer, the REST console, the cluster dashboard and the JSON diff, with limits — currently one connection window, three tabs per tool, documents opened in a dialog rather than a tab, built-in themes only, and no comments or trailing commas in request bodies. Feature availability, limits, and behavior for the free edition are determined by us and may change over time.

Rubber Pro

Rubber Pro is the paid edition: it lifts the limits of the free edition and grants the right to use the App commercially. It is bought inside the App through the Apple App Store, currently as a monthly or a yearly auto-renewing subscription, or as a one-time lifetime purchase; all of them unlock the same Rubber Pro. The plans on offer, their prices and what they include are the ones presented at the point of sale at the time you buy, and may change for future purchases.

Commercial use means any use in the course of employment, of freelance or contract work, or of the business of a company or other organization — including use against a cluster that belongs to an employer or a client. Such use requires Rubber Pro — an active subscription or a lifetime purchase. The free edition is for personal projects, evaluation and learning.

Subscriptions

If you subscribe to a paid plan, your subscription will automatically renew at the end of each billing period unless you cancel it before the renewal date. Subscriptions purchased through the App Store are billed by Apple and are subject to Apple's terms, including auto-renewal and cancellation procedures. You can manage or cancel your subscription through your Apple ID account settings. Refunds for purchases made through the App Store are handled by Apple in accordance with Apple’s policies.

A cancellation takes effect at the end of the billing period already paid for; until then Rubber Pro stays active. If the price of a subscription changes, Apple notifies you in advance and, where the law or Apple's rules require it, asks for your consent before the new price applies.

If a subscription lapses, the App keeps working as the free edition — within the limits of that edition and for personal, non-commercial use. Nothing you created in the App is deleted when it does.

A Rubber Pro subscription bought in an earlier version of the App carries over to this version on the same Apple ID.

Lifetime Purchase

A lifetime purchase is a single payment that unlocks Rubber Pro for the App it was bought for, on the Apple ID that bought it, without a recurring charge and without an expiry date, and it includes the updates we publish for that App. "Lifetime" refers to the lifetime of the App, not of the purchaser: it does not oblige us to keep publishing updates, to keep the App available on the App Store, or to support every future version of macOS. On another Mac signed in to the same Apple ID, use Restore Purchases in the App to unlock it again.

A lifetime purchase is granted to the purchasing user and is not transferable except as we permit in writing. It does not extend to a different application we may publish in the future, even one that succeeds this App; whether Rubber Pro bought this way carries over to such an application, and on what terms, would be stated at that time. Like any other App Store purchase, it is billed by Apple and refunded by Apple under Apple's policies (section 3).

Free Trials, Offer Codes and Promotions

We may offer free trials, introductory prices, or promotional and offer codes for Rubber Pro. When a free or discounted period of a subscription ends, the subscription renews automatically at its then-current regular price unless you cancel it at least 24 hours before the period ends. Codes have no cash value, cannot be sold or exchanged, may be limited to one per Apple ID, may expire, and are redeemed through the App Store subject to Apple's terms. A code that was obtained fraudulently or in breach of the rules of the promotion that issued it may be refused or revoked.

A giveaway, contest or other promotion we run is governed by the rules we publish with it, in addition to these Terms; where the two differ, the promotion's rules prevail for that promotion.

3. Payment & Refunds

All prices, taxes and payment terms are as presented at the time of purchase. For App Store purchases and subscriptions, Apple processes payments and handles receipts. Any refund requests for purchases made through the App Store must be submitted to Apple; we may assist but cannot directly issue refunds for App Store transactions. For purchases made directly from us (if offered), refund terms will be displayed at the point of sale.

4. Functionality & Use

Rubber is a GUI tool for connecting to and managing Elasticsearch and OpenSearch clusters. It is intended to assist with debugging, development, and administrative tasks such as running requests (including exporting as cURL), viewing and editing documents, bulk operations, templates, and index management. The App supports features including (but not limited to): multiple connections, tabs, pinned indices and aliases, a table view of documents, large JSON handling, bulk requests, export of requests as cURL, saved templates, a cluster dashboard, a JSON diff, read-only connections, Mutual TLS, SSH tunnels, HTTP and SOCKS5 proxies, and themes. It works with Elasticsearch 6 through 9 and with OpenSearch. Features may be added, changed or removed over time.

The App requires either an internet connection or local network connectivity to reach your targets. You may connect to remote clusters over the internet or to local clusters on your LAN. All connectivity and data access are initiated by you; we do not connect to your clusters on our own.

5. User Responsibilities

• Cluster Control: You are solely responsible for the configuration, security, integrity, backup, and content of any Elasticsearch / OpenSearch clusters you connect to using the App.

• Credentials: You are responsible for safeguarding credentials, keys, and certificates used by the App. Do not share credentials with others unless authorized by you.

• Safe Use: Use caution when performing write or destructive operations. The App provides tools that can modify or delete data—these actions are irreversible within the target system unless you have backups.

6. No Hosting, No Data Collection of Database Content

We do not host, receive, store, or have access to your database contents, queries, or connection details as part of normal operation. All interactions with your Elasticsearch or OpenSearch environments occur directly between your device and the target cluster. The limited information the Service does handle — purchase records, feedback you send us, and website analytics — is described in our Privacy Policy.

7. Restrictions

You agree not to, and will not permit others to:

• Reverse engineer, decompile, disassemble, or attempt to derive the source code of the App, except to the extent expressly permitted by applicable law;

• Modify, adapt, translate, or create derivative works of the App;

• Redistribute, resell, rent, lease, sublicense, or provide the App as a service to third parties without our express written permission;

• Remove or alter any proprietary notices, labels, or marks in the App;

• Use the free edition for commercial purposes without Rubber Pro.

8. Third-Party Components & Services

The App may use or integrate with third-party services and open-source components. Your use of those services may be subject to additional terms and privacy policies. We are not responsible for third-party services and have no control over their content or practices.

9. Updates

We may provide updates, upgrades, or patches to the App. Updates are delivered through the App Store, according to your update settings, and may be needed to keep using some features or to keep purchases working. Updates may be subject to additional terms which will be provided when applicable.

10. Warranty Disclaimer

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND. BINARY WORK, LLC DISCLAIMS ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, INCLUDING WITHOUT LIMITATION ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, OR THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, OR FREE FROM HARMFUL COMPONENTS.

11. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL BINARY WORK, LLC, ITS AFFILIATES, SUPPLIERS, OR LICENSORS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, OR DATA USE, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF OR INABILITY TO USE THE APP, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. OUR AGGREGATE LIABILITY ARISING OUT OF OR RELATED TO THESE TERMS SHALL NOT EXCEED THE AMOUNTS PAID BY YOU FOR THE APP IN THE SIX (6) MONTHS PRECEDING THE CLAIM (OR ONE HUNDRED U.S. DOLLARS (US$100) IF NO AMOUNTS WERE PAID).

12. Indemnification

You agree to indemnify, defend and hold harmless Binary Work, LLC and its officers, directors, employees, agents, affiliates and partners from and against any claims, liabilities, damages, losses and expenses (including reasonable attorneys' fees and costs) arising out of or in any way connected with: (a) your misuse of the App; (b) your violation of these Terms; (c) your violation of applicable laws; or (d) any activity conducted through your use of the App.

13. Termination

We may suspend or terminate your access to the App or Services, with or without notice, if you breach these Terms. Upon termination, your license to use the App will terminate and you must stop all use of the App. Provisions which by their nature are intended to survive termination (including sections on Restrictions, Warranty Disclaimer, Limitation of Liability, Indemnification, and Governing Law) will survive.

14. Export Compliance

You agree to comply with all export and import laws and regulations that apply to the App. You shall not directly or indirectly export, re-export, transfer or otherwise dispose of the App to any country, entity or person prohibited by applicable law.

15. Governing Law & Dispute Resolution

These Terms will be governed by and construed in accordance with the laws of the State of California, United States, without regard to its conflict of law provisions. Any dispute, claim or controversy arising out of or relating in any way to these Terms shall be resolved exclusively in the state or federal courts located in San Luis Obispo County, California, and you submit to the personal jurisdiction of those courts.

16. Changes to These Terms

We may modify these Terms from time to time. If we make material changes, we will provide notice via the App, our website, or email to the address you provide. Your continued use of the App after the effective date of changes constitutes your acceptance of the updated Terms.

17. Severability

If any provision of these Terms is held to be invalid or unenforceable, that provision will be struck and the remaining provisions will remain in full force and effect.

18. Assignment

You may not assign or transfer these Terms, by operation of law or otherwise, without our prior written consent. We may assign these Terms without restriction.

19. Entire Agreement

These Terms, together with any documents they expressly incorporate (including the Privacy Policy), constitute the entire agreement between you and Binary Work, LLC regarding the App and supersede any prior agreements between you and Binary Work, LLC relating to the App.

20. App Store Terms

If you obtained the App through the Apple App Store, the following also applies:

• Parties. These Terms are concluded between you and Binary Work, LLC only, and not with Apple Inc. ("Apple"). We, not Apple, are solely responsible for the App and its content.

• Scope of license. Your license is limited to using the App on Apple-branded products that you own or control, as permitted by the Usage Rules set out in Apple's Media Services Terms and Conditions, except that the App may be accessed by other accounts associated with you through Family Sharing or volume purchasing, where Apple makes it available.

• Maintenance and support. We are solely responsible for providing any maintenance and support for the App, as specified in these Terms or as required by applicable law. Apple has no obligation to furnish any maintenance or support services for the App.

• Warranty. We are solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price for the App to you; to the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App, and any other claims, losses, liabilities, damages, costs or expenses attributable to a failure to conform to a warranty are our responsibility.

• Product claims. We, not Apple, are responsible for addressing any claims by you or a third party relating to the App or your possession or use of it, including product liability claims, claims that the App fails to conform to a 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, we, not Apple, are solely responsible for the investigation, defense, settlement and discharge of that claim.

• Legal compliance. You represent and warrant that you are not located in a country that is subject to a U.S. Government embargo or that has been 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.

• Developer contact. Questions, complaints or claims about the App should be directed to Binary Work, LLC, 6890 Avila Valley Dr., San Luis Obispo, CA 93405, United States, or to the email address in section 21.

• Third-party terms. You must comply with any applicable third-party terms when using the App, such as the terms of the services that host the clusters you connect to.

• Third-party beneficiary. Apple and its subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce them against you as a third-party beneficiary.
