Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to download, install, and use the App on Apple-branded devices that you own or control, solely for your personal, non-commercial use, in accordance with these Terms and the Apple App Store Terms of Service.

7. Disclaimer of Warranties

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE APP IS PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE. WE SPECIFICALLY DISCLAIM ALL IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.

Without limiting the foregoing, we do not warrant or represent that:

• The App will meet your specific requirements or expectations.
• The App will be uninterrupted, timely, secure, or error-free.
• The 2FA codes generated by the App will always be accurate or accepted by third-party services.
• The breach detection feature will identify all compromised or weak passwords.

• Any defects or errors in the App will be corrected.
• iCloud Sync or iCloud Backup will function without interruption or data loss.
• The App's encryption implementation is impervious to all current or future attacks.

You acknowledge that the security of any system depends on multiple factors, many of which are outside our control (e.g., operating system vulnerabilities, device compromises, user behavior). The App is one component of a broader security strategy, and you should not rely on it as your sole security measure.

8. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW:

• IN NO EVENT SHALL THE DEVELOPER, ITS AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, LICENSORS, OR SUPPLIERS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, including but not limited to: loss of data, loss of revenue, loss of profits, loss of business, loss of goodwill, business interruption, cost of procurement of substitute goods or services, unauthorized access to or alteration of your data, or any other intangible losses, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
• IN NO EVENT SHALL OUR TOTAL AGGREGATE LIABILITY to you for all claims arising out of or relating to these Terms or the use of the App EXCEED THE GREATER OF: (A) THE AMOUNT YOU ACTUALLY PAID US FOR THE APP IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM, OR (B) FIFTY US DOLLARS (USD $50.00).

10. Data and Privacy

Your use of Keyfort is also governed by our Privacy Policy, which is incorporated into these Terms by reference. By using the App, you consent to the practices described in the Privacy Policy.

Key points:

• We operate with a zero-knowledge architecture — we cannot access, recover, or reset your data.
• If you lose your device, your PIN, your Apple ID, and have no backups, your data is permanently lost. We cannot help you recover it.
• You are solely responsible for maintaining access to your data through backups and device security.

11. Account Deletion & Data Removal

You may delete all your data at any time:

• Within the App: Settings > Data > Delete All Data permanently removes all App data from your device.
• iCloud Data: Disabling iCloud Sync removes synced data from your iCloud container.
• Uninstalling: Removing the App deletes all locally stored data. Note that some Keychain items may persist until explicitly deleted or the device is factory reset.
• Apple Account: You can also manage or delete iCloud data through your Apple ID settings.

12. Updates & Changes to the App

• We may release updates to the App from time to time. Updates may add, modify, or remove features.
• We are not obligated to provide updates, maintenance, support, or new features.
• Continued use of the App after updates constitutes acceptance of any changes.
• We recommend keeping the App updated to the latest version for security and compatibility reasons.

13. Availability & Discontinuation

• We do not guarantee that the App will be available at all times or in all regions.
• We reserve the right to discontinue the App or any feature at any time, with or without notice.
• In the event of discontinuation, we will make reasonable efforts to provide advance notice through the App or App Store listing to allow you to export your data.

• We reserve the right to terminate or suspend your access to the App at our discretion, without prior notice, for conduct that we believe violates these Terms, is harmful to other users, or is otherwise objectionable.
• Upon termination, all licenses granted herein immediately expire. Sections 5, 7, 8, 9, 15, 16, 17, and 18 shall survive termination.

15. Dispute Resolution

15.1 Informal Resolution

Before initiating any formal dispute resolution, you agree to first contact us at [email protected] and attempt to resolve the dispute informally for at least 30 days.

15.2 Binding Arbitration

If we cannot resolve the dispute informally, you and we agree that any dispute, claim, or controversy arising out of or relating to these Terms or the App shall be resolved through binding individual arbitration rather than in court, except that either party may seek equitable relief in court for intellectual property infringement or misappropriation.

15.3 Class Action Waiver

YOU AND THE DEVELOPER AGREE THAT EACH PARTY MAY BRING CLAIMS AGAINST THE OTHER ONLY IN YOUR OR ITS INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, CONSOLIDATED, OR REPRESENTATIVE ACTION OR PROCEEDING. If this provision is found to be unenforceable, then the entirety of this arbitration section shall be null and void.

15.4 Small Claims Exception

Notwithstanding the above, either party may bring an individual action in small claims court for disputes within the court's jurisdictional limits.

16. Governing Law

These Terms shall be governed by and construed in accordance with the laws of the jurisdiction in which the Developer is located, without regard to its conflict of law provisions. If you are a consumer located in the European Union, you may also benefit from mandatory provisions of the law of your country of residence.

17. Severability

If any provision of these Terms is held to be invalid, illegal, or unenforceable by a court of competent jurisdiction, such provision shall be modified to the minimum extent necessary to make it enforceable, or if modification is not possible, shall be severed from these Terms. The invalidity of any provision shall not affect the validity and enforceability of the remaining provisions.

18. General Provisions

18.1 Entire Agreement

These Terms, together with the Privacy Policy, constitute the entire agreement between you and the Developer regarding your use of the App and supersede all prior or contemporaneous communications, agreements, and understandings, whether oral or written.

18.2 Waiver

The failure of the Developer to enforce any right or provision of these Terms shall not constitute a waiver of such right or provision. Any waiver must be in writing and signed by the Developer to be effective.

18.3 Assignment

You may not assign or transfer these Terms or any rights or obligations hereunder without our prior written consent. We may assign these Terms without restriction.

18.4 Force Majeure

We shall not be liable for any failure or delay in performance resulting from causes beyond our reasonable control, including but not limited to: acts of God, natural disasters, pandemic, war, terrorism, government actions, power or internet failures, Apple service disruptions, or other events beyond our control.

18.5 No Third-Party Beneficiaries

These Terms are for the benefit of you and the Developer only. No third party shall have any right to enforce any provision of these Terms, except that Apple and its subsidiaries are third-party beneficiaries of these Terms as set forth in the Apple App Store Terms of Service.

18.6 Apple-Specific Terms

These Terms are between you and the Developer, not Apple. The Developer, not Apple, is solely responsible for the App and its content. Apple has no obligation to furnish maintenance or support services for the App. In the event of any failure of the App to conform to applicable warranties, you may notify Apple, and Apple will refund the purchase price (if any); to the maximum extent permitted by applicable law, Apple has no other warranty obligation. Apple is not responsible for addressing any claims by you or third parties relating to the App.

19. Modifications to Terms

We reserve the right to modify these Terms at any time. When we make material changes:

• The updated Terms will be posted at this URL with a new "Last Updated" date.
• Material changes may be communicated through the App or App Store release notes.
• Your continued use of the App after the effective date of revised Terms constitutes your acceptance of the changes.
• If you do not agree to the revised Terms, you must stop using the App and delete it from your device.
