1. XTide includes a harmonics file (tide data) for the United States only due to legal issues with the data from other countries, but supports custom harmonics files.
2. You should not use this program or any data files that might be distributed with it if anyone or anything could come to harm as a result of an incorrect tide prediction.
3. The author assumes no liability for damages arising from use of this program OR of any 'harmonics data' that might be distributed with it.
4. (Accurate tide predictions can only be made if the 'harmonics data' for the relevant location are good.
5. Unfortunately, the only way the maintainer of those data has of knowing when they are bad is when someone with access to authoritative tide predictions or observations reports a problem.
6. XTide's predictions do not incorporate the effects of tropical storms, El Niño, seismic events, subsidence, uplift, or changes in global sea level.
7. XTide provides tide and current predictions in a wide variety of formats.
