1Acceptance of these Terms
By downloading, installing, or using Jumpstash (the "Service"), you agree to be bound by these Terms of Service ("Terms") and our Privacy Policy, which is incorporated by reference. If you do not agree, do not install or use the Service.
The Service is provided by Danger Close Security Co., a New Jersey corporation, doing business as Jumpstash ("Jumpstash", "we", "us", "our").
2The Service
Jumpstash is a native authenticator application for Apple platforms that generates time-based one-time passwords (TOTP) on your device from secrets you supply. The Service includes the Jumpstash iOS, iPadOS, macOS, and watchOS applications, the Jumpstash AutoFill credential provider extension, watch complications, and any related documentation or assets distributed under the Jumpstash name.
Jumpstash is a single-purpose tool. It does not provide hosting, backup, recovery, or customer-data storage services. Your TOTP secrets are stored in Apple's iCloud Keychain on your own devices; see the Privacy Policy for details.
3Your license to use Jumpstash
Subject to these Terms, we grant you a limited, personal, non-exclusive, non-transferable, revocable license to install and use Jumpstash on Apple-branded devices that you own or control, for personal or internal business purposes.
You may not:
- copy, modify, or create derivative works of the Service;
- reverse engineer, decompile, or disassemble the Service, except to the extent applicable law permits despite this restriction;
- rent, lease, lend, sell, sublicense, or otherwise commercially exploit the Service;
- remove, alter, or obscure any proprietary notices contained in the Service; or
- use the Service to violate any law or the rights of any third party.
4Your responsibilities
Two-factor authentication secrets are sensitive. You are responsible for:
- Securing your Apple ID and devices. Because your codes are stored in iCloud Keychain, anyone who can unlock your devices or sign in as you can access them.
- Backups and exports. If you use the export feature
to write codes to a file (JSON,
otpauth://URIs, or QR images), that file contains your TOTP secrets in cleartext. Storing or sharing it is at your own risk. - Keeping recovery options elsewhere. Jumpstash does not store the recovery codes the underlying services issue. Keep those somewhere you can access if you lose your devices.
You agree not to use the Service in any manner that could damage, disable, overburden, or impair Apple's systems, or interfere with any other party's use of the Service.
5Apple App Store terms
You acquired Jumpstash through the Apple App Store. The following provisions apply with respect to that distribution channel and are in addition to anything stated elsewhere in these Terms:
- These Terms are between you and Jumpstash only, not with Apple. Apple is not responsible for the Service or its content.
- Your license to use Jumpstash is limited to use on an Apple-branded device that you own or control, as permitted by Apple's Licensed Application End User License Agreement (the "Apple LEULA"). To the extent the Apple LEULA and these Terms conflict on the topics it covers, the Apple LEULA applies.
- Apple has no obligation to provide any maintenance or support for the Service. Maintenance and support, where provided, are provided by us.
- If the Service fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price (if any). To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the Service.
- You and Jumpstash acknowledge that Apple is a third-party beneficiary of these Terms and, upon your acceptance, will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary thereof.
- 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.
6Intellectual property
The Service, including its source code, design, brand, name, and logo, is owned by Danger Close Security Co. and is protected by copyright, trademark, and other laws. Nothing in these Terms transfers any intellectual property rights to you other than the limited license granted in section 3.
7Third-party components
Jumpstash includes the following open-source components, each licensed under its own terms:
- CryptoSwift — used for HMAC computation within the TOTP algorithm.
- SwiftOTP — used for TOTP code generation.
- SwiftBase32 — used for decoding base32-encoded secrets.
These components run entirely on-device and do not make network requests. Their respective licenses are reproduced inside the Service and govern your use of those components.
8Availability & updates
We may release updates to the Service from time to time, including changes to features, supported platforms, and required operating-system versions. We may also discontinue the Service at any time. Because the Service operates entirely on your device against iCloud Keychain, your existing codes will continue to function within other compatible authenticator apps even if Jumpstash itself becomes unavailable — provided you have an export.
9Disclaimer of warranties
THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, NON-INFRINGEMENT, OR THAT THE SERVICE WILL BE UNINTERRUPTED OR ERROR-FREE. YOU USE THE SERVICE AT YOUR OWN RISK.
We do not warrant that the Service will meet your requirements, that it will be compatible with any particular hardware or software configuration, or that any defects will be corrected.
10Limitation of liability
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL DANGER CLOSE SECURITY CO. OR ITS OFFICERS, DIRECTORS, EMPLOYEES, OR AGENTS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, DATA, USE, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR RELATING TO YOUR USE OF — OR INABILITY TO USE — THE SERVICE.
To the extent any liability cannot be excluded under applicable law, our total cumulative liability to you for all claims arising out of or relating to the Service will not exceed the greater of (a) the amount you paid us for the Service in the twelve months preceding the event giving rise to the claim, or (b) USD $25.
Jumpstash is a free download and we do not collect payment from you directly. The cap above exists to make the limit concrete, not to suggest there is a typical refund pathway.
11Indemnification
You agree to indemnify and hold harmless Danger Close Security Co. and its officers, directors, employees, and agents from any claim, demand, loss, liability, or expense (including reasonable attorneys' fees) arising out of or related to (a) your use of the Service in violation of these Terms, (b) your violation of any law or third-party right, or (c) any content you choose to store in or export from the Service.
12Termination
You may terminate these Terms at any time by uninstalling the Service. We may terminate or suspend your access to the Service at any time, with or without cause, including if we believe you have violated these Terms. Sections 6 (Intellectual property), 9 (Disclaimer), 10 (Limitation of liability), 11 (Indemnification), 13 (Governing law), and 15 (Severability & entire agreement) survive termination.
13Governing law
These Terms are governed by the laws of the State of New Jersey, United States, without regard to its conflict-of-laws principles. To the extent permitted by applicable law, the exclusive forum for any dispute relating to the Service is the state and federal courts located in the State of New Jersey, and you consent to the personal jurisdiction of those courts.
If you are a consumer located outside the United States, applicable local consumer-protection laws may provide you with rights in addition to those granted here, and nothing in these Terms limits those rights.
14Changes to these Terms
We may update these Terms from time to time. Material changes will be reflected by updating the "Last updated" date at the top of this page. Continued use of the Service after the changes take effect constitutes acceptance of the revised Terms.
15Severability & entire agreement
If any provision of these Terms is held to be unenforceable, that provision will be modified to the minimum extent necessary to make it enforceable, and the remaining provisions will remain in full force and effect. These Terms, together with the Privacy Policy and the Apple LEULA where applicable, constitute the entire agreement between you and Jumpstash with respect to the Service and supersede any prior agreements on the same subject.
16Assignment
You may not assign or transfer these Terms, by operation of law or otherwise, without our prior written consent. We may assign these Terms at any time without notice, including in connection with a merger, acquisition, or sale of substantially all of our assets.
