Terms and Conditions
Effective Date: March 1, 2026 • Last Updated: March 2026 • Application ID: io.securitylab.ciphernote
1. Acceptance of Terms
By installing, copying, accessing, or utilizing the CipherNote application (“Application” or “Software”), you enter into a legally binding agreement with the development team (“we,” “our,” or “us”). If you do not consent to every provision within these Terms and Conditions, you are strictly prohibited from downloading, installing, or executing the Software and must uninstall it immediately.
2. Description of Application & License Grant
CipherNote is a standalone, client-side utility built for the Android platform, designed to provide a 100% offline, zero-permission note taking and encryption studio with client-side caesar and base64 cipher utilities, markdown tools, and secure vaults.
We grant you a revocable, non-exclusive, non-transferable, limited license to download, install, and execute the Application strictly for personal, non-commercial, and lawful purposes in accordance with these Terms.
3. 100% Offline Architecture & Local Data Responsibility
CipherNote operates with a strict 100% Offline Architecture. The Software does not communicate with external servers, cloud databases, or third-party storage infrastructure. Consequently:
- All user configurations, entries, records, and databases are stored exclusively within your local hardware device sandbox.
- We possess no server-side access to your data and are physically incapable of inspecting, recovering, restoring, or reconstructing any records deleted or corrupted by hardware failure, operating system clearing, or accidental uninstallation.
- You are solely responsible for executing periodic on-device backups and safeguarding your physical device.
4. Intellectual Property Rights
The Application, including its underlying source code, visual components, graphical assets, algorithms, documentation, and trade dress, is the intellectual property of the developers and is protected under international copyright, trademark, and trade secret laws. You shall not reverse-engineer, decompile, disassemble, or derive source code from compiled binaries except where permitted by applicable statutory law.
5. User Conduct & Permissible Use
You agree not to use the Application to:
- Violate any local, national, or international statute, ordinance, or administrative regulation.
- Attempt to circumvent device-level Android sandbox security controls.
- Redistribute modified, tampered, or repackaged binaries bearing the package identifier
io.securitylab.ciphernotewithout explicit authorization.
6. Cryptographic & Key Recovery Disclaimer
CipherNote implements local client-side cipher algorithms (including Caesar shift and Base64 encoding). You acknowledge that CipherNote is designed for personal obfuscation and offline note management. Because CipherNote operates completely offline with zero master key recovery servers, the developer cannot recover, decrypt, or restore any notes if you forget your cipher key or discard your device. CipherNote is provided as-is and is not certified for enterprise cryptographic compliance, national defense secrets, or classified communications.
7. Disclaimer of Warranties (“AS IS”)
THE APPLICATION IS PROVIDED ON AN “AS IS” AND “AS AVAILABLE” BASIS WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, WORKMANSHIP, TITLE, ACCURACY, QUIET ENJOYMENT, OR NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APPLICATION WILL OPERATE ERROR-FREE, UNINTERRUPTED, OR COMPATIBLE WITH EVERY FUTURE VERSION OF ANDROID.
8. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL THE DEVELOPERS, CONTRIBUTORS, OR AFFILIATES BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES (INCLUDING LOSS OF PROFITS, DATA CORRUPTION, DEVICE DAMAGE, WORK INTERRUPTION, HEALTH OR FINANCIAL MISJUDGMENTS) ARISING OUT OF OR IN CONNECTION WITH THE USE OR INABILITY TO USE THE APPLICATION, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
9. Zero OS Permissions Verification
You acknowledge that CipherNote deliberately omits network (android.permission.INTERNET), camera, external storage, and location permissions. The Application relies on local storage mechanisms provided directly by Android. Any perceived lack of remote synchronization or real-time cloud backup is an intentional architectural privacy feature.
10. Modifications to Software & Terms
We reserve the right to revise or modify these Terms and Conditions periodically. Updated terms will be published at this web address. Your continued retention or usage of the Application subsequent to any modifications constitutes explicit acceptance of the revised Terms.
11. Governing Law & Severability
These Terms shall be interpreted, construed, and enforced in accordance with applicable general commercial principles and the laws of the developer's jurisdiction, without regard to conflicts of law rules. If any provision of these Terms is deemed invalid or unenforceable, the remaining provisions shall remain in full force and effect.
