Dispute Resolution

Informal Negotiations

To expedite resolution and control the cost of any dispute, controversy, or claim related to these Legal Terms (each a “Dispute” and collectively, the “Disputes”) brought by either you or us (individually, a “Party” and collectively, the “Parties”), the Parties agree to first attempt to negotiate any Dispute (except those Disputes expressly provided below) informally for at least 30 days before initiating arbitration.

Binding Arbitration

Any dispute arising out of or in connection with these Legal Terms, including any question regarding its existence, validity, or termination, shall be referred to and finally resolved by the International Commercial Arbitration Court under the European Arbitration Chamber (Belgium, Brussels, Avenue Louise, 146) according to the Rules of this ICAC, which, as a result of referring to it, is considered as the part of this clause. The language of the proceedings shall be Portuguese. The governing law of these Legal Terms shall be substantive law of Portugal.

Restrictions

The Parties agree that any arbitration shall be limited to the Dispute between the Parties individually. To the full extent permitted by law, (a) no arbitration shall be joined with any other proceeding; (b) there is no right or authority for any Dispute to be arbitrated on a class-action basis or to utilize class action procedures; and (c) there is no right or authority for any Dispute to be brought in a purported representative capacity on behalf of the general public or any other persons.

Exceptions to Informal Negotiations and Arbitration

The Parties agree that the following Disputes are not subject to the above provisions concerning informal negotiations binding arbitration: (a) any Disputes seeking to enforce or protect, or concerning the validity of, any of the intellectual property rights of a Party; (b) any Dispute related to, or arising from, allegations of theft, piracy, invasion of privacy, or unauthorized use; and (c) any claim for injunctive relief. If this provision is found to be illegal or unenforceable, then neither Party will elect to arbitrate any Dispute falling within that portion of this provision found to be illegal or unenforceable and such Dispute shall be decided by a court of competent jurisdiction within the courts listed for jurisdiction above, and the Parties agree to submit to the personal jurisdiction of that court.

Corrections

There may be information on the Services that contains typographical errors, inaccuracies, or omissions, including descriptions, pricing, availability, and various other information.

Where applicable law does not permit the complete exclusion of liability, our total aggregate liability for all such claims shall be limited to the smallest amount permitted by that law and shall in no event exceed the total amount you paid us, if any, for the Services in the twelve (12) months preceding the event giving rise to the claim.

WEB APPLICATIONS

This section contains additional terms that apply specifically to our web application How High Am I?, a free online GPS altimeter.

Client-Side Processing

How High Am I? is a free, client-side web application that displays your current altitude using your device’s GPS. All processing happens entirely in your browser — your location and altitude are never uploaded to our servers.

Measurement Accuracy (Web Application)

We make no warranties about the accuracy, reliability, or precision of the elevation shown. GPS-derived altitude is an estimate and is typically less accurate than GPS horizontal position. It depends on your device’s GPS hardware, satellite signal quality, and environmental conditions such as buildings, tunnels, and tree cover. GPS altitude is measured against a reference model of the Earth and may differ from surveyed height above sea level. The reading should be treated as approximate.

Safety Warning: The altitude shown is an estimate for informational purposes only. It must NOT be used for aviation, skydiving, paragliding, diving decompression planning, mountaineering safety decisions, or any activity where an incorrect altitude reading could lead to injury, loss, or death. Do not use it as evidence in legal proceedings, insurance claims, or official documentation.

Third-Party Services (Web Application)

When you use How High Am I?, your browser interacts with the following third-party services:

  • Formspree: Processes contact form submissions when you use the contact page.
  • OpenPanel: Self-hosted analytics for anonymous usage statistics.
