TAFCast — Terms of Service & User Agreement

Version 1.2 · Effective 2026-10-12

1. Operator and scope

TAFCast (“we”, “us” and “our”) provides the Service from Lisbon, Portugal. Contact: tafcast@outlook.com.

These Terms cover the TAFCast website, browser and installed web apps (including iOS), Android app, widgets, notifications, and associated backend services, together the “Service”.

2. Acceptance and eligibility

Select “I agree” to accept these Terms and the Safety Disclaimer. You can read them before accepting. Closing a screen, pressing Back, or reading a document is not acceptance. If you do not agree, do not use the Service. The Privacy Notice explains how personal data are processed; acknowledging it does not provide blanket consent.

The Service is available free of charge to individuals and organisations worldwide, for personal, educational, and professional reference, subject to these Terms and applicable law. No pilot licence or account is required. If local law requires a parent or guardian's authorisation for your use, obtain it. If accepting for an organisation, you must have authority to bind it. Professional access does not permit operational aviation use prohibited below.

3. Permission to use

We grant you a non-exclusive, worldwide, royalty-free permission to access and use the Service for the reference purposes described here while you comply with these Terms. Access is free; your own connectivity and device charges remain your responsibility.

This permission does not transfer ownership of our software or branding or allow you to sell, sublicense, impersonate, or commercially redistribute the Service without permission. Rights granted under applicable open-source or data licences remain unaffected. Any restrictions on reverse engineering or interoperability are subject to rights that applicable law does not allow us to restrict.

4. Aviation safety and intended use

The Safety Disclaimer forms part of these Terms. The Service is not an official MET/AIS source and must not be used for navigation, flight planning, dispatch, or flight-safety decisions. Always obtain the appropriate current official briefing. The Service does not assess airworthiness, aircraft limitations, pilot qualifications, runway suitability, or legal operating minima.

Synthetic Airfield Outlooks are illustrative model output, not official forecasts. Data gaps, stale caches, filtered notices, estimated wind components, and missed notifications are inherent limitations to consider. A displayed category, colour, threshold, or runway indicator is not a clearance, recommendation to fly, or assurance of safety.

5. Service quality and mandatory rights

We do not promise uninterrupted availability, complete geographic coverage, delivery of every alert, or that third-party data, translations, decoding, forecasts, or calculations will always be accurate or current. The Service is offered on an “as available” basis to the extent applicable law permits.

These descriptions of limitations do not exclude statutory guarantees, duties of care, or remedies that cannot lawfully be excluded. Any mandatory consumer rights concerning supply, conformity, updates, or remedies remain available where applicable.

6. Responsibility and liability

Responsibility for loss or damage is determined under applicable law. These Terms do not exclude or limit liability for death, personal injury, harm to health or moral integrity, fraud, intentional misconduct, gross negligence, or any other liability that cannot lawfully be excluded or limited, including applicable non-contractual liability for property damage.

You remain responsible for your own use and aviation decisions. That responsibility does not release us from our own legal obligations. We do not guarantee the conduct or availability of independent providers, but their involvement does not remove rights you have against us under mandatory law. Stopping use is not your exclusive legal remedy.

7. Acceptable use

Do not use the Service unlawfully, interfere with its operation, introduce malicious code, bypass access controls, or access systems without authorisation. Do not make automated or bulk requests that disrupt the Service or exceed published limits. Contact us to discuss bulk access.

Third-party data remain subject to their applicable licences. These Terms do not grant redistribution rights we do not hold. Applicable licences may independently give you rights to use underlying data; restrictions on access to our servers do not take those rights away.

8. Third-party sources and platforms

The Service uses sources including NOAA Aviation Weather Center, FAA, Open-Meteo, autorouter, IPMA, and OurAirports, depending on feature and availability. Attribution and source identification do not imply endorsement. Providers may change data, coverage, or availability.

Google Play, your browser, operating system, and any independently selected backend have their own terms for their services. They are not parties to this agreement. These Terms do not override applicable open-source licences or mandatory platform rights.

9. Changes, suspension and discontinuation

We may change the Service for maintenance, security, legal compliance, data-provider changes, or sustainable operation. For significant reductions or discontinuation, we will provide reasonable advance notice in the Service or on the website where practicable. Urgent security, legal, or abuse issues may require immediate restrictions. Restrictions will be proportionate to their reason.

Material changes to these Terms will be explained before they take effect and presented for renewed agreement. They do not retrospectively change rights relating to earlier events. Merely changing a date or continuing use will not be treated as renewed agreement. You may stop using the Service at any time. Applicable notice, termination, and other mandatory rights are preserved.

10. Portuguese law and disputes

These Terms are governed by Portuguese law. If you are a consumer, this choice does not deprive you of mandatory protections of the law of your habitual residence where those protections apply. Courts with jurisdiction are determined by applicable law; these Terms do not require consumers to bring claims exclusively in Portugal or waive applicable local court rights.

Please contact tafcast@outlook.com about a concern. Contacting us first is encouraged, not a condition for exercising legal rights. No compulsory arbitration or class-action waiver is imposed by these Terms.

11. Contact and interpretation

Contact: tafcast@outlook.com. If a provision is invalid or unenforceable, its treatment and the effect on the rest of the agreement are determined by applicable law. No provision is intended to reduce mandatory legal protections. These Terms do not create rights for independent data providers or app stores to enforce unrelated obligations against you.
