3. IMPORTANT DISCLAIMER - Recreational Purposes Only

4. Eligibility and Age Requirements

4.1 Age Requirement

You must be at least 18 years of age to use the Service in the UK and Europe. By using the Service, you represent that you meet this age requirement.

United States Users: If you are in the US, you must be at least 13 years of age. Users between 13 and 18 should have parental or guardian consent.

5. Personal Use Only

5.1 General Rule

The Service is made available to you under the right to access set out in Section 8.2, for your personal, non-commercial use only. You may use the Service for your own personal practice, but you must not use it to provide training or instruction to others, to operate a training program, to debrief, or for any commercial or revenue-generating purpose without our prior written permission.

5.2 Instructor and Examiner Limited Use

Where we grant prior written permission for instructor, examiner, or similar professional use (including use of the Service as a visual aid), that permission is subject to the following terms, which apply in addition to, and do not replace, the rest of these Terms:

• The permission is personal to the named recipient, non-transferable, and revocable by us at any time by written notice (including by email)
• The Service may be used only as a visual aid or illustration tool; it must not be presented to any student, candidate, or third party as authoritative, certified, approved, or as a source that can be relied upon without independent verification
• The Service is not, and must not be held out as, aviation training, examination content, or any part of a flight test, skill test, proficiency check, or licence revalidation (see Section 3.2)
• The recipient or user remains solely responsible, in both a professional and personal capacity, for the correctness of anything shown to, or discussed with, a student, trainee, cadet, candidate or other third party
• Before using the Service in the presence of, or with reference to, any student, trainee, cadet, candidate, or other third party, the recipient must expressly inform that person (a) that the Service is a simulator for personal practice only, (b) that it is not training, examination, or assessment material and does not form part of any lesson, test, check, or record, and (c) that nothing shown by the Service may be relied upon as authoritative, accurate, or as a record of any kind
• The recipient must not include any output, screenshot, recording, score, or result from the Service in any formal training record, logbook entry, test report, examination document, or licensing submission
• The recipient warrants that their use of the Service with any third party complies with all applicable aviation regulations and with the rules of any approved training organisation, declared training organisation, flight training organisation, employer, or regulatory or licensing authority under whose authority they operate or to whom they are accountable
• All disclaimers, warranty exclusions, liability caps, and indemnities in these Terms (including Sections 3, 9, 10, and 11) continue to apply in full to the recipient and to the recipient's use of the Service with third parties
• The recipient must hold a current Pro Tier Subscription for the duration of such use, unless we agree otherwise in writing

Written permission under this Section is only valid if given by an email sent from an @radionavigator.app address by RHBA, and must expressly identify the named recipient, the scope of permitted use, and any duration or conditions. Nothing else constitutes written permission, including (without limitation) verbal statements, telephone calls, messages on social media, chat, or third-party platforms, emails from any other address, discount codes, promotional offers, pricing arrangements, or prior conduct. Nothing in this Section 5.2 grants any licence, approval, endorsement, or accreditation.

6. Subscriptions and Payments

6.1 Free Tier

The Free Tier provides limited access at no cost. Features may be changed without notice.

6.2 Pro Tier Subscription

The Pro Tier requires a paid Subscription providing access to advanced navigation instruments and extended functionality.

6.3 Payment Processing

All payments are processed through Paddle (paddle.com). By subscribing, you will be required to agree to their Terms of Service and Privacy Policy.

6.4 Account Creation via Checkout

When you purchase a Pro subscription:

• An account will be automatically created using your payment email address
• You consent to this account creation by completing the checkout process
• This account allows you to access Pro features and manage your subscription
• You can set a password later via the "Set Password" prompt in your account settings

6.5 Automatic Renewal

6.6 Free Trial

United States users (FTC ROSCA Rule, California ARL, New York GBL §527-a): The Free Trial is one (1) day. After the trial ends your payment method will be charged the recurring Subscription price shown at checkout, and will continue to be charged on the recurring billing cycle until you cancel. The recurring charge amount, billing frequency, and trial-end date are shown to you at checkout, and a confirmation containing the same information is emailed to you by Paddle. You may cancel at any time, online and without speaking to anyone, through any of the methods in Section 6.9. These Terms together with the disclosures shown at the Paddle checkout constitute your express informed consent to the auto-conversion and to recurring billing.

6.7 Refunds and Right of Withdrawal

If you are a UK or EU/EEA consumer, you have a statutory 14-day right to withdraw from your subscription. Radio Navigator Pro is supplied to you as both a digital service (the interactive simulator, trainers and account features) and as digital content (the lessons, courses, trainers), and these Terms apply to both elements of the supply together.

The 14-day cancellation period runs from the day you complete checkout. For users who started with a Free Trial, the period runs concurrently with the trial and continues into the paid subscription that follows. You may additionally cancel during the Free Trial itself at any time, at no charge.

By accepting these Terms at checkout you (a) expressly request that we begin supplying Radio Navigator Pro to you immediately, without waiting for the 14-day cancellation period to expire, and (b) give your express consent and acknowledgement that, once you have accessed Pro features, you thereby lose your right of withdrawal. Pro features and Pro content are delivered to you immediately on checkout completion (and immediately at trial start, for trial users), so performance of the contract begins at that point. Once you have accessed any Pro feature, the right of withdrawal is extinguished and no refund is available under it.

To exercise the right of withdrawal before you have accessed Pro features, email accounts@radionavigator.app indicating that you wish to invoke your 14-day right of withdrawal. A clear statement in writing is sufficient; no specific form is required. Where this right is validly exercised, we will refund the full subscription price paid for the current term to your original payment method within 14 days of receiving your notice.

If you cancel during the Free Trial before the trial ends, no charge is taken and there is nothing to refund.

Where any other refund is due (for example, where a charge has been taken in error), we will refund you using the same payment method you used for the original payment, unless you expressly agree otherwise.

For refund requests beyond statutory rights, please contact accounts@radionavigator.app. All refund requests are handled on a case-by-case basis.

6.8 Device Limits

Each Pro Subscription is licensed for use by a single individual on up to 2 devices simultaneously. If you sign in on a third device, the oldest active session will be automatically signed out. Account sharing is prohibited under Section 7 of these Terms, and repeated violations may result in account suspension or termination under Section 13.

6.9 How to Cancel

You may cancel your Subscription anytime by:

1. Account Settings - Log in and navigate to Subscription settings
2. Email - Send cancellation request to support@radionavigator.app
3. Paddle Portal - Use subscription management link (sent in confirmation email)

Upon cancellation, you retain access to Pro features until the end of your current billing period.

You acknowledge that simulation results may differ from real-world conditions and must never be relied upon for actual navigation or flight operations.

Consumer Rights: If you are a consumer in the UK or EU/EEA, your statutory rights under consumer protection laws are not affected by these disclaimers to the extent they cannot be excluded by law.

10.0 Risk Allocation

You acknowledge that the restrictions on use in Section 3 (Recreational Purposes Only) and Section 5 (Personal Use Only), together with the warranty disclaimers in Section 9, the liability limits in this Section 10, and the indemnity in Section 11, together allocate the risks of using the Service between you and us. These provisions are a fundamental part of the commercial basis on which the Service is offered at its current price (including any Free Trial under Section 6.6), and we would not make the Service available on these terms without them.

This exclusion applies regardless of the legal theory (contract, tort, negligence, strict liability, or otherwise) and whether or not we were advised of the possibility of such damages.

This cap applies in aggregate to all claims, regardless of the number of events or causes of action.

We use third-party service providers for authentication, payments, hosting, security, and related functions. A full list of these providers, their roles, and the legal bases on which they process your personal data is set out in our Privacy Policy.
