3.3 The Licensor may change the pricing of the Software at any time. Price changes do not affect licenses already purchased.

4. SEPARATELY LICENSED COMPONENTS

4.1 The quantum-crypto library included in the Software is licensed under the Business Source License (BSL). Your use of quantum-crypto is governed solely by the terms of the BSL license, which can be found in the LICENSE file within the quantum-crypto repository on GitHub.

4.2 Nothing in this Agreement restricts, limits, or otherwise modifies your rights under the BSL license with respect to the quantum-crypto library. In the event of a conflict between this Agreement and the BSL license regarding quantum-crypto, the BSL license shall prevail.

4.3 All other components of the Software are Proprietary Components and are governed exclusively by this Agreement.

5. RESTRICTIONS ON PROPRIETARY COMPONENTS

5.1 Except to the extent that the following restrictions are prohibited by applicable law that cannot be excluded by agreement (including any non-waivable right to observe, study, test, or decompile software solely to achieve interoperability), you shall not reverse-engineer, decompile, disassemble, or otherwise attempt to derive the source code, underlying algorithms, data structures, or architectural design of any Proprietary Component of the Software, whether in whole or in part, by any means.

5.2 You shall not modify, adapt, translate, or create derivative works based on any Proprietary Component of the Software.

6. INTELLECTUAL PROPERTY

6.1 The Proprietary Components, including all source code, object code, user interface designs, algorithms, architecture, documentation, trademarks, trade names, and trade secrets embodied therein, are and shall remain the exclusive property of TURBOBOOSTTECHNOLOGIES.

6.2 No title or ownership interest in any Proprietary Component is transferred to you under this Agreement. All rights not expressly granted herein are reserved by the Licensor.

6.3 You acknowledge that the Proprietary Components contain valuable trade secrets and confidential information belonging to the Licensor, and you agree to maintain the confidentiality thereof.

7. VAULT DATA, PRIVACY, AND DATA RESPONSIBILITY

7.1 The Software is designed to operate locally on your devices. It does not require account creation, does not collect personal data, and does not transmit any Vault Data to the Licensor. The only network communications initiated by the Software are: (a) local-network synchronization directly between your own devices, as described in Section 8, which does not involve any server operated by the Licensor; and (b) the optional Sentinel compromise check described in Section 9, which communicates with a third-party breach database. The handling of information in connection with the Software is further described in the Privacy Policy.

7.2 All Vault Data is stored locally on your device and encrypted using the cryptographic methods provided by the quantum-crypto library.

7.3 YOU ARE SOLELY RESPONSIBLE FOR REMEMBERING AND SAFEGUARDING YOUR MASTER PASSWORD OR BIOMETRIC CREDENTIALS USED TO UNLOCK 9KEYRING. THE LICENSOR DOES NOT HAVE ACCESS TO YOUR MASTER PASSWORD, DOES NOT STORE IT, AND CANNOT RECOVER OR RESET IT UNDER ANY CIRCUMSTANCES.

7.4 YOU ARE SOLELY RESPONSIBLE FOR MAINTAINING BACKUPS OF YOUR VAULT DATA. THE LICENSOR SHALL NOT BE LIABLE FOR ANY LOSS, CORRUPTION, OR INACCESSIBILITY OF VAULT DATA, REGARDLESS OF CAUSE, INCLUDING BUT NOT LIMITED TO DEVICE FAILURE, SOFTWARE MALFUNCTION, FORGOTTEN CREDENTIALS, OR FAILED SYNCHRONIZATION.

7.5 The Licensor makes no representation or guarantee that any password, credential, or data stored in the Software will remain accessible, intact, or recoverable at any time.

8. SYNCHRONIZATION

8.1 The Software synchronizes Vault Data directly between your devices over your local network, using local network discovery (mDNS). Synchronization occurs device-to-device: no Vault Data is transmitted to, routed through, or stored on any server operated by the Licensor.

8.2 All Vault Data transmitted during synchronization is end-to-end encrypted before leaving your device.

8.3 The Licensor may introduce additional synchronization or connectivity methods in future updates. Any such methods will be subject to additional or revised terms presented to you at that time in accordance with Section 19.

8.4 The Licensor does not guarantee the availability or reliability of any synchronization feature, and shall not be liable for any data loss, corruption, synchronization failure, or any other issue arising from the use of mDNS or any other synchronization method.

9. SENTINEL AND VAULTLIGHT

9.1 Sentinel, the credential monitoring feature, provides informational alerts regarding the strength, age, reuse, or potential compromise of stored credentials, and other security-related characteristics of stored items (such as insecure website URLs). Sentinel's assessments are provided on an as-is basis and do not constitute security advice or a guarantee of security.

9.2 To check whether a stored credential appears in known data breaches, Sentinel queries the Have I Been Pwned ("HIBP") service, an independent third-party breach database. These checks use a k-anonymity protocol: only a short, truncated prefix of a one-way cryptographic hash of the credential is transmitted, and matching is completed locally on your device. Your plaintext passwords, full password hashes, and Vault Data never leave your device. When Sentinel performs a check, HIBP and its infrastructure providers necessarily receive your device's IP address and standard connection metadata. HIBP is not operated by the Licensor, and its availability and accuracy are not guaranteed. Sentinel's breach checks can be disabled in the Software's settings. If a breach check cannot be completed, Sentinel falls back to local, offline strength heuristics. All Sentinel analysis other than HIBP breach checks is performed entirely on your device and involves no network communication.

9.3 VaultLight provides in-app search functionality. The Licensor makes no warranty regarding the completeness or accuracy of VaultLight search results.

10. THIRD-PARTY SOFTWARE AND PLATFORM REQUIREMENTS

10.1 The Software may incorporate third-party libraries and frameworks, including but not limited to the Qt framework (used under applicable license). Such components are subject to their own respective licenses, which are provided within the Software or its documentation.

10.2 Apple App Store. If you obtained the Software through the Apple App Store, the following additional terms apply:

(a) This Agreement is concluded between you and the Licensor only, and not with Apple Inc. ("Apple"). The Licensor, not Apple, is solely responsible for the Software and its content.

(b) The Licensor, not Apple, is solely responsible for providing any maintenance and support services with respect to the Software. Apple has no obligation whatsoever to furnish any maintenance or support services.

(c) Apple is not responsible for addressing any claims by you or any third party relating to the Software, including product liability claims, claims that the Software fails to conform to legal or regulatory requirements, and claims arising under consumer protection or similar legislation.

(d) In the event of any failure of the Software to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the Software to you. To the maximum extent permitted by applicable law, Apple has no other warranty obligation whatsoever with respect to the Software.

(e) You represent and warrant that you are not located in a country subject to a U.S. Government embargo or designated as a "terrorist supporting" country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.

(f) Apple and Apple's subsidiaries are third-party beneficiaries of this Agreement and, upon your acceptance of this Agreement, Apple will have the right (and will be deemed to have accepted the right) to enforce this Agreement against you as a third-party beneficiary hereof.

10.3 Your use of the Software on Android is also subject to the Google Play Terms of Service. In the event of a conflict, the Google Play Terms shall prevail to the extent required by Google.

11. EXPORT COMPLIANCE

The Software contains cryptographic functionality and may be subject to export control and import laws and regulations of Canada, the United States, and other jurisdictions.

THE SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE LICENSOR DISCLAIMS ALL WARRANTIES, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, AND SECURITY.

THE LICENSOR DOES NOT WARRANT THAT: (A) THE SOFTWARE WILL BE UNINTERRUPTED, ERROR-FREE, OR FREE OF VIRUSES OR OTHER HARMFUL COMPONENTS; (B) THE SOFTWARE WILL MEET YOUR REQUIREMENTS OR EXPECTATIONS; (C) ANY STORED DATA WILL REMAIN SECURE, INTACT, OR RECOVERABLE; OR (D) ANY DEFECTS IN THE SOFTWARE WILL BE CORRECTED.

YOU ACKNOWLEDGE THAT THE USE OF THE SOFTWARE FOR STORING SENSITIVE CREDENTIALS AND DATA IS AT YOUR OWN RISK.

13. LIMITATION OF LIABILITY

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL THE LICENSOR, ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, OR AFFILIATES BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO:

(A) LOSS OF PASSWORDS, CREDENTIALS, OR OTHER VAULT DATA; (B) LOSS OF PROFITS, REVENUE, OR BUSINESS OPPORTUNITIES; (C) LOSS OF DATA OR DATA CORRUPTION; (D) COST OF PROCUREMENT OF SUBSTITUTE SERVICES; (E) UNAUTHORIZED ACCESS TO OR ALTERATION OF YOUR DATA; (F) BUSINESS INTERRUPTION; (G) ANY OTHER PECUNIARY LOSS;

ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT OR THE USE OR INABILITY TO USE THE SOFTWARE, WHETHER BASED ON WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR ANY OTHER LEGAL THEORY, EVEN IF THE LICENSOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

IN NO EVENT SHALL THE LICENSOR'S TOTAL AGGREGATE LIABILITY UNDER THIS AGREEMENT EXCEED THE AMOUNT YOU ACTUALLY PAID FOR THE SOFTWARE IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM, OR TEN CANADIAN DOLLARS (CAD $10.00), WHICHEVER IS GREATER.

14. CONSUMER PROTECTION

Some jurisdictions do not allow the exclusion of certain warranties, the limitation of liability for certain types of damages, or restrictions on where consumers may bring legal proceedings. If you are a consumer, nothing in this Agreement excludes, limits, or modifies any right or remedy, or any guarantee, warranty, or other term or condition, implied or imposed by applicable consumer protection law (including, without limitation, the Consumer Protection Act (Ontario), the Consumer Protection Act (Quebec), and applicable consumer protection laws of the European Union, the United Kingdom, and Australia) that cannot lawfully be excluded, limited, or modified. In such cases, the disclaimers and limitations in Sections 12, 13, and 17 apply only to the maximum extent permitted by such law.

15. INDEMNIFICATION

You agree to indemnify, defend, and hold harmless the Licensor from and against any and all claims, liabilities, damages, losses, costs, and expenses (including reasonable legal fees) arising from or related to: (a) your use or misuse of the Software; (b) your breach of this Agreement; or (c) your violation of any applicable law or regulation.
