1.4 Obfuscation & Code Protection

The Software contains proprietary obfuscation, code protection, and anti-reverse-engineering measures ("Code Armor").

• The localhost REST API (port 7777) is provided for local use only. You may not expose it to public networks, the internet, or any remote systems.
• Session tokens are generated per unlock and must be treated as confidential credentials. ProTusk is not responsible for unauthorized access resulting from your failure to protect session tokens.
• ProTusk is not responsible for any actions taken by third-party AI tools that access the API, including but not limited to data modification, deletion, or corruption.

1.6 Updates & Modifications

ProTusk may release updates, patches, or new versions of the Software at its sole discretion. This EULA applies to all such updates unless a separate agreement accompanies the update. ProTusk has no obligation to provide updates, support, or maintenance.

Section 2

Privacy Policy

ProTusk is committed to protecting your privacy. This Privacy Policy describes what information we collect (and do not collect), how we handle it, and your rights under California law, including the California Consumer Privacy Act (CCPA/CPRA) and the California Online Privacy Protection Act (CalOPPA).

2.1 Data We Do NOT Collect

The Software does not collect, transmit, or share any of the following:

• Personal information (name, email, address, phone number, government identifiers)
• Device information (hardware ID, OS version, IP address, MAC address)
• Usage data, analytics, or telemetry of any kind
• API keys, tokens, secrets, passwords, or any data you store in the vault
• Crash reports, error logs, or diagnostic data
• Cookies, tracking pixels, or browser fingerprints
• Location data

The Software makes zero network requests. It does not connect to the internet, phone home, check for updates automatically, or communicate with any server. All encryption, decryption, and storage operations occur entirely on your local device.

2.2 Local Data Storage

The Software stores your encrypted vault file locally on your device using your operating system's standard application data directory. This file is encrypted with AES-256-GCM and can only be decrypted with your master password. ProTusk has no ability to access, read, recover, or decrypt your vault data. If you lose your master password, your data is permanently unrecoverable.

2.3 AI Edition API (Personal-AI & Customer-AI)

The AI editions include a localhost-only REST API on port 7777. This API operates exclusively on your local machine (127.0.0.1) and does not transmit data over any network. Communication between the API and external AI tools occurs entirely within your local system. ProTusk does not receive, intercept, log, or have any access to API requests or responses.

2.4 Purchase Transactions

Purchases are processed by our third-party payment processor, LemonSqueezy (Lemon Squeezy, LLC). ProTusk does not directly collect or store your payment information (credit card numbers, billing addresses, etc.). LemonSqueezy's handling of your payment data is governed by their own Privacy Policy. We may receive limited transaction information from LemonSqueezy (e.g., order confirmation, license key, email address used for purchase) solely for the purpose of fulfilling your order and providing customer support.

2.5 Marketing Website (protusk.com)

Our marketing website hosted on GitHub Pages may use standard GitHub Pages infrastructure, which may log IP addresses as part of standard web server operations. ProTusk does not add any additional tracking, analytics, cookies, or third-party scripts beyond LemonSqueezy's checkout overlay. We do not use Google Analytics, Facebook Pixel, or any other tracking service.

2.6 Children's Privacy

The Software is not directed at children under the age of 13. We do not knowingly collect personal information from children. Since the Software collects no data, this provision is included for regulatory completeness.

2.7 Your Rights Under California Law (CCPA/CPRA)

Under the California Consumer Privacy Act and the California Privacy Rights Act, California residents have the right to know what personal information is collected, request deletion, and opt out of the sale or sharing of personal information. Because ProTusk collects no personal information whatsoever from the Software, there is no data to disclose, delete, or opt out of. If you believe we hold any personal information about you, you may contact us at the address below, and we will respond within 45 days as required by law.

2.8 Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last Updated" date. Your continued use of the Software after any changes constitutes acceptance of the revised policy.

3.3 Maximum Aggregate Liability

IN NO EVENT SHALL PROTUSK'S TOTAL CUMULATIVE LIABILITY TO YOU FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THIS EULA OR THE SOFTWARE EXCEED THE AMOUNT YOU ACTUALLY PAID TO PROTUSK FOR THE SOFTWARE IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR TEN UNITED STATES DOLLARS ($10.00 USD), WHICHEVER IS GREATER.

3.5 Essential Basis of the Bargain

You acknowledge that ProTusk has set its prices and entered into this EULA in reliance upon the disclaimers of warranty and the limitations of liability set forth herein, that the same reflect an allocation of risk between the parties (including the risk that a contract remedy may fail of its essential purpose and cause consequential loss), and that the same form an essential basis of the bargain between the parties.

Section 4

Indemnification

You agree to indemnify, defend, and hold harmless ProTusk and its officers, directors, employees, agents, affiliates, successors, and assigns from and against any and all claims, damages, obligations, losses, liabilities, costs, and expenses (including reasonable attorneys' fees) arising from or related to:

• Your use or misuse of the Software;
• Your violation of this EULA or any applicable law or regulation;
• Your violation of any third-party rights, including intellectual property, privacy, or contractual rights;

• Any third-party claims arising from your use of the AI edition REST API;
• Your failure to maintain the confidentiality of your master password or session tokens;
• Any unauthorized access to your vault or API resulting from your negligence.

This indemnification obligation shall survive the termination of this EULA and your use of the Software.

5.6 Severability

If any provision of this EULA is held to be unenforceable or invalid under any applicable law, such unenforceability or invalidity shall not render this EULA unenforceable or invalid as a whole.
