The software is not guaranteed to be:

• error-free
• secure
• continuously available
• compatible with your hardware, operating system, browser, files, sensors, or data formats
• complete, current, or accurate in its results

2. Informational Use Only

All outputs, calculations, visualizations, statistics, analyses, maps, comparisons, and derived values generated by the software are provided for informational and convenience purposes only.

This includes, without limitation:

• GPS positions
• timestamps
• distance
• speed
• pace
• ascent / descent
• elevation
• gradients
• energy or calorie estimates
• route matching
• activity classification
• historical comparisons
• map overlays
• imported or converted track data

Such values may be incomplete, estimated, delayed, distorted, or incorrect.

3. Not for Safety-Critical or High-Risk Use

This software is not a certified navigation, rescue, dispatch, safety, or mission-critical system.

It must not be used as the sole basis for:

• navigation or route-finding in hazardous environments
• terrain, weather, avalanche, flood, traffic, or other environmental risk assessment
• emergency response or rescue operations
• safety-critical tracking of persons, vehicles, or assets
• operational decisions where failure, downtime, or inaccurate output could cause injury, death, property damage, regulatory issues, or major business disruption

Real-world conditions may differ substantially from what is shown in the software.

Always verify important information independently using appropriate official, professional, or safety-grade sources.

4. Not Medical, Health, or Training Advice

This software does not provide medical, health, rehabilitation, coaching, or professional sports science advice.

Any estimated metrics relating to performance, exertion, energy expenditure, recovery, fatigue, fitness, or similar topics are approximate and may be incorrect.

Do not use this software as a substitute for qualified medical or professional advice.

5. Data Import, Export, and Integrity

The software may import, parse, convert, transform, merge, export, or display data from files and services such as GPX, FIT, TCX, sensors, maps, APIs, and other third-party or user-provided sources.

The authors make no representation that:

• imported files will be interpreted correctly
• metadata will be preserved
• exports will be lossless
• timestamps or coordinates will remain correct
• calculations will match those of devices or third-party platforms
• conversions will preserve all fields or semantics

Data corruption, parser differences, coordinate drift, rounding differences, timezone issues, missing metadata, duplication, truncation, and other inconsistencies can occur.

You are solely responsible for verifying important results and keeping backups of your original data.

• installation and configuration
• updates and patching
• backups and restore procedures
• firewalling and reverse proxy setup
• access control and authentication
• encryption and secrets management
• monitoring and operational security
• data retention and legal compliance

The authors are not responsible for damage, outages, data exposure, security incidents, account compromise, or loss arising from self-hosting or deployment choices.

7. Third-Party Services, Maps, and Data Sources

This project may depend on or interoperate with third-party services, APIs, map providers, tile servers, geocoding services, elevation sources, package registries, or other external components.

Such services and data sources may:

• change without notice
• impose separate terms or licenses
• become unavailable
• contain errors or omissions
• rate-limit, block, throttle, or charge for access

The authors are not responsible for the legality, availability, performance, licensing status, or correctness of third-party services or content.

• use of the software
• inability to use the software
• incorrect calculations, analyses, or visualizations
• incorrect or incomplete GPS, map, or elevation data
• import, export, parsing, or conversion errors
• data loss or corruption
• downtime, bugs, or vulnerabilities
• third-party services or dependencies
• self-hosting or deployment errors
• reliance on software output

however caused and on any theory of liability, whether in contract, tort (including negligence), strict liability, or otherwise.

This limitation applies even if the possibility of such damages was known or should have been known.
