End User License Agreement

License Grant

Copyright © 2026 Paige Julianne Sullivan.

This End-User License Agreement ("EULA") is a legal agreement between you and Paige Julianne Sullivan ("Company") for the TuneBit software product ("Software"). By installing, copying, or otherwise using the Software, you agree to be bound by the terms of this EULA.

Upon purchase of a license, TuneBit grants you a non-exclusive, non-transferable right to use the Software on the number of computers permitted by your subscription plan (5 PCs on the Personal plan, unlimited PCs via a USB-bound license on the Technician plan) for a term of one (1) year. A 7-Day Free Trial is available to evaluate the Software before purchase.

Restrictions

• You may not reverse engineer, decompile, or disassemble the Software.
• You may not rent, lease, or lend the Software.
• You may not distribute, sublicense, or sell copies of the Software.

THE SOFTWARE IS PROVIDED “AS IS”, WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. IN NO EVENT SHALL THE COMPANY OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.

Assumption of Risk

The Software is designed to modify system settings, registry entries, services, installed applications, drivers, and other operating system components. The Software requires Administrator privileges to perform its functions.

BY USING THIS SOFTWARE, YOU EXPRESSLY UNDERSTAND AND AGREE THAT YOU ASSUME ALL RISK ARISING FROM YOUR USE OF THE SOFTWARE.

This includes, without limitation, risk of:

• Data loss or corruption
• System instability or failure
• Loss of installed applications or user settings
• Registry damage
• Boot failure or inability to start Windows
• Driver incompatibility or hardware malfunction
• Loss of network connectivity
• Degraded system performance
• Security vulnerabilities introduced by changes to system configuration

You are solely responsible for maintaining adequate backups of your data and system state before using the Software. The Company has no obligation to assist in recovering from any system changes made by the Software.

YOU EXPRESSLY ACKNOWLEDGE AND AGREE THAT USE OF THE SOFTWARE IS AT YOUR SOLE AND EXCLUSIVE RISK. THE COMPANY SHALL NOT BE LIABLE FOR ANY DAMAGE TO YOUR SYSTEM, DATA, OR FILES RESULTING FROM YOUR USE OF THE SOFTWARE.

Network Behavior and Data Handling

The Software is designed to operate locally on your device. It does not transmit telemetry, analytics, crash reports, usage tracking, or inventory data to the Company. Diagnostic information surfaced inside the Software — including hardware inventory, event logs, registry scan results, BSOD minidump analysis, license codes, and any other data displayed by individual tools — remains on your device and is not transmitted to the Company or any third party.

The complete list of outbound network operations the Software performs is enumerated below. Each call uses HTTPS over the standard TLS port. All endpoints listed below are operated by the Company except where explicitly noted.

License validation

• Endpoint: https://tunebit.app/api/validate-license.php
• Method: HTTPS POST, JSON body.
• Frequency: Once per launch when online. If the server is unreachable, the locally cached license remains valid for up to three (3) days before re-validation is required.
• Data transmitted: Your signed license code (which contains only your hardware fingerprint and the license expiry date — both values the Software already possesses locally).
• Data received: A JSON response indicating whether the license is valid, revoked, expired, or unknown.

Trial license issuance

• Endpoint: https://tunebit.app/register.php
• Method: HTTPS POST, form-encoded.
• Frequency: Once per device, on the first launch of a new install that has no existing license, only if the Software has not been previously deactivated on the device.
• Data transmitted: The device's hardware fingerprint — a SHA-256 hash derived locally from immutable hardware identifiers. The fingerprint is not a serial number, MAC address, or other identifier capable of being correlated to you outside of the Company's own license database.
• Data received: A signed seven (7)-day trial license code bound to the submitted fingerprint.

Update check and download

• Endpoints: https://dist.tunebit.app/VERSION and https://dist.tunebit.app/TuneBit.exe
• Method: HTTPS GET.
• Frequency: The version probe runs once per launch when online. The binary download executes only after you explicitly click Yes on the update-available prompt.
• Data transmitted: Standard HTTPS request metadata (the .NET runtime's default User-Agent and the URL). No identifying information is added by the Software.
• Data received: Either the current version string (text/plain) or the new signed Software binary.

VirusTotal file hash lookup (opt-in, bring-your-own-key)

• Endpoint: https://www.virustotal.com/api/v3/files/{sha256} — operated by Google / Chronicle, not by the Company.
• Method: HTTPS GET, authenticated with an x-apikey header.
• API key: The Software does not include a VirusTotal API key. Sign up for a free (or paid) account at virustotal.com and paste your personal API key into the VirusTotal module before using the feature. Your key is stored locally — in the Windows registry at HKCU\Software\TuneBit\VirusTotal\ApiKey on fixed-drive installs, or in a virustotal.ini file next to TuneBit.exe on portable / USB-bound installs — and is sent only to VirusTotal's own servers as the x-apikey HTTP header. It is never transmitted to the Company.
• Frequency: Only when you explicitly invoke the Scan File control inside the VirusTotal module against a specific file.
• Data transmitted: The SHA-256 hash of the selected file, plus your VirusTotal API key as authentication. The contents of the file are never transmitted — only the hash. The Company has no visibility into these requests; they are subject to VirusTotal's own privacy policy, terms of service, and rate limits.

No other network activity

Aside from the four operations above, the Software performs no outbound network communication. In particular, the Software does not:

• Send analytics or telemetry of any kind
• Send crash reports or stack traces
• Transmit hardware inventory, registry contents, event logs, BSOD minidumps, scan results, or any other diagnostic data
• Maintain a persistent connection to any server
• Include any third-party advertising or tracking SDKs
• Modify outbound traffic generated by other applications on your device

Network traffic to the Company's domains (tunebit.app, dist.tunebit.app) may be safely blocked at the firewall level. In that case the Software relies on the locally cached license through its three (3)-day offline grace period and otherwise operates with full functionality, save for update notifications and the opt-in VirusTotal lookups.

Stripe billing (web portal only)

Payment processing for subscriptions is handled exclusively through the Company's website at tunebit.app and the Stripe-hosted billing portal. The Software itself does not initiate billing-related network calls and does not receive, process, or store your payment-method data. Stripe's processing of payment information is governed by Stripe's own privacy policy.
