Subject to these Terms and the access level associated with your account, MBP grants you a personal, non-exclusive, non-transferable license to use MBP Drone.

5. Accounts

You are responsible for maintaining control of that email account and for activity performed through your MBP Drone account.
We may restrict or terminate access where we reasonably believe an account is being abused, shared improperly, used fraudulently, used to circumvent access controls, or used in violation of these Terms.
6. Plans & Purchases
MBP Drone may offer free, monthly, lifetime, or other access plans. Available features and prices are shown before purchase.
A monthly plan renews and is billed on a recurring monthly basis until cancelled.
Cancellation stops future recurring charges. Access already paid for may continue until the end of the applicable paid period unless otherwise stated.
A lifetime plan means a one-time payment for continued access to the applicable MBP Drone plan for as long as MBP Drone is operated and that plan remains supported. It does not mean the lifetime of the purchaser and does not constitute a promise that MBP Drone will be operated indefinitely.
Payments are processed through third-party payment providers such as PayPal.
Refunds, cancellations, charge disputes, and other payment matters are handled according to the terms presented at purchase, applicable payment-provider rules, and applicable law.

MBP Drone may be made available as beta or pre-release software.
Beta software may contain defects, incompatibilities, incomplete features, or behavior that changes during development.
We may add, modify, replace, or remove features as MBP Drone develops. We may also modify technical requirements, supported browsers, audio packages, or other aspects of the service.
We will not intentionally remove paid access solely to require the same customer to purchase the same access again, but particular features and technical implementations may change over time.

Availability may be affected by maintenance, hosting providers, browsers, operating systems, network connectivity, third-party services, security incidents, or circumstances outside our control.
Offline functionality is provided where supported but is not guaranteed to work indefinitely or on every browser or device.
