This End User License Agreement ("Agreement") is a binding contract between you ("you") and Nir Nagar ("we", "us", "our"), the developer of the PresenceLock software and its documentation ("the App"). By downloading, installing, or using the App, you confirm that you have read, understood, and agree to this Agreement, and that you are of legal age to enter into it. If you do not agree, do not install or use the App, and uninstall it.
PLEASE READ THIS AGREEMENT CAREFULLY. It contains important provisions that disclaim warranties, limit and cap our liability, place responsibility for your data and devices on you, require you to use the App lawfully and only from official sources, and require you to indemnify us in certain cases. These provisions apply to the maximum extent permitted by the law that applies to you, and they survive even after you stop using the App.
We grant you a personal, limited, non-exclusive, non-transferable, non-sublicensable, revocable license to install and use the App on devices you own or control, for your personal or internal business use, in accordance with this Agreement. The App is licensed, not sold. We and our licensors retain all right, title, and interest in and to the App, and all rights not expressly granted to you are reserved.
You may not, and may not permit anyone else to: (a) copy, distribute, resell, rent, lease, sublicense, publish, or otherwise make the App available to others, except installing it on your own devices as intended; (b) modify, adapt, translate, or create derivative works of the App; (c) reverse engineer, decompile, or disassemble the App, or attempt to derive its source code, except to the limited extent this restriction cannot be excluded under applicable law; (d) remove, alter, or obscure any proprietary notice; (e) use the App to develop a competing product; or (f) bypass, disable, or tamper with any security, licensing, or technical-protection feature of the App.
You understand and agree that the App:
%LOCALAPPDATA%\PresenceLock.All of this stays on your device. See the Privacy Policy for details.
The App is a privacy and convenience lock that operates while the App is running. It is not encryption, account-level access control, or a guaranteed security measure. It can be bypassed by a technical user, for example by ending the App's process, by using Safe Mode, or by accessing files or apps through other means. Do not use it as your only protection for confidential or sensitive information. You are solely responsible for protecting sensitive data by other means, such as disk encryption and a locked operating-system account.
Your PINs (master and per-app "friend" PINs) are stored only as one-way hashes and cannot be recovered by us or by the App. If you forget a PIN, your options are to use another enabled unlock method or to reset by removing the App's data folder, which clears your methods and codes.
When you choose "Close app" at a lock prompt, the App asks the locked application to close. The App may also attempt to confirm that application's own exit dialog on your behalf. You are responsible for any unsaved work in an application you choose to close.
Install PresenceLock only from our official page or the Microsoft Store. A tampered or "cracked" copy of a lock app is especially dangerous: people who pirate this kind of app often hide malware inside it, and a fake lock screen can capture what you type. Downloading, installing, or distributing a cracked, pirated, or otherwise unauthorized copy is a breach of this Agreement, may be illegal, and is done entirely at your own risk. This Agreement, including the no-warranty and limitation-of-liability terms, and any responsibility on our part, apply only to genuine copies you obtain from our official channels; we are not responsible for any copy obtained elsewhere or for any harm such a copy causes.
THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE", WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, WE DISCLAIM ALL WARRANTIES AND CONDITIONS, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING ANY IMPLIED WARRANTIES OR CONDITIONS OF MERCHANTABILITY, SATISFACTORY QUALITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, ACCURACY, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE, THAT ANY APP WILL BE LOCKED OR UNLOCKED AT ANY PARTICULAR MOMENT, THAT THE LOCK CANNOT BE BYPASSED, OR THAT THE APP WILL MEET YOUR REQUIREMENTS. NO ADVICE OR INFORMATION, WHETHER ORAL OR WRITTEN, CREATES ANY WARRANTY.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL WE BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE, OR CONSEQUENTIAL DAMAGES, OR FOR ANY LOSS OR CORRUPTION OF DATA, LOSS OF WORK IN A CLOSED APPLICATION, LOSS OF PROFITS, REVENUE, GOODWILL, OR BUSINESS, BUSINESS INTERRUPTION, COST OF SUBSTITUTE PRODUCTS, DAMAGE TO DEVICES, ACCESS TO A PROTECTED APP BY ANOTHER PERSON, OR LOSS OF PRIVACY, ARISING OUT OF OR RELATED TO THE APP OR THIS AGREEMENT, WHETHER BASED ON CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR ANY OTHER THEORY, AND EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THE APP OR THIS AGREEMENT WILL NOT EXCEED THE GREATER OF (a) THE AMOUNT YOU ACTUALLY PAID FOR THE APP IN THE TWELVE MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (b) USD 10.
Some jurisdictions do not allow the exclusion or limitation of certain warranties or damages, so some of the above may not apply to you. Nothing in this Agreement excludes or limits any liability or right that cannot be excluded or limited under the law that applies to you, including your non-waivable rights as a consumer.
To the maximum extent permitted by applicable law, you agree to defend, indemnify, and hold us harmless from and against any claims, damages, losses, liabilities, costs, and expenses (including reasonable legal fees) arising out of or related to: (a) your use or misuse of the App; (b) your breach of this Agreement or of any law or third-party right; or (c) your use of the App on a device or against an application you were not authorized to control.
The App runs on Microsoft Windows and relies on components we do not provide or control, including Windows Hello, your Bluetooth and WiFi hardware and drivers, and the Microsoft Store. We are not responsible for those components, or for any act, omission, failure, or change in them. Your use of Windows and the Microsoft Store is also governed by the terms of their respective providers.
You agree not to misuse the App, including not to: use it to conceal information unlawfully, to evade legal obligations, or in violation of the rights of others; use it to lock or control a computer or an application without the permission of the person entitled to use it; or use it in violation of any applicable law.
You represent that you are not located in, and will not use or export the App in violation of, any applicable export-control or sanctions laws, and that you are not on any restricted-party list under such laws.
We may release updates that add, change, or remove features, and we may update this Agreement. The current version will be posted at this address with a new "Last updated" date. Your continued use of the App after a change takes effect means you accept the updated Agreement; if you do not agree, stop using and uninstall the App.
This license ends automatically if you breach this Agreement, and we may suspend or end it where permitted by law. You may end it at any time by uninstalling the App. The provisions that by their nature should survive (including the license restrictions, disclaimers, limitations and cap on liability, indemnification, and governing law) survive termination.
This Agreement, together with the Privacy Policy, is the entire agreement between you and us about the App and supersedes any prior understanding on its subject. If any provision is held unenforceable, it will be modified to the minimum extent necessary to make it enforceable, or severed, and the remaining provisions will stay in full force. Our failure to enforce a provision is not a waiver of it. You may not assign this Agreement without our prior written consent; we may assign it in connection with a merger, acquisition, or sale of assets. Section headings are for convenience only.
This Agreement is governed by the laws of the State of Israel, without regard to its conflict-of-laws rules, and the competent courts located in Tel Aviv-Yafo, Israel will have exclusive jurisdiction over any dispute arising out of or related to it. This does not deprive you of the protection of any mandatory consumer-protection law of your country of residence, where such law applies.
If you choose to send us suggestions, ideas, bug reports, or other feedback about the App, you grant us a perpetual, irrevocable, worldwide, transferable, royalty-free right to use, modify, and incorporate that feedback for any purpose, without any obligation, attribution, or compensation to you, and we are equally free not to use it.
The App is a consumer application intended for ordinary home use. It is not designed, tested, certified, or licensed for use in any high-risk or safety-critical environment or activity, including medical or life-support systems, emergency services, aviation, nuclear facilities, or any other setting in which a failure, error, or delay of the App could lead to death, personal injury, or severe physical, property, or environmental damage. You must not use the App in any such environment, and, to the maximum extent permitted by applicable law, we accept no responsibility or liability for any such use.
To the maximum extent permitted by applicable law, any claim arising out of or relating to the App or this Agreement must be brought within twelve (12) months after the event giving rise to the claim first occurred; otherwise, the claim is permanently barred. Where the law that applies to you does not permit such a limitation, the shortest limitation period that it does permit applies instead.
This Agreement was drafted in English. Translations, including the German version, are provided for convenience only. To the extent permitted by applicable law, if there is any inconsistency between the English version and a translation, the English version prevails.
This Agreement is between you and us only, and creates no rights for, and may not be enforced by, any other person. Microsoft and other platform, store, or component providers are not parties to this Agreement and owe you no obligations under it. We will not be liable for any failure or delay caused by circumstances beyond our reasonable control.
