Terms of use

These terms apply to tailnav.com, its pages and any software we provide to connect a receiver (together, "TailNav"). TailNav is operated by TailNav ("we", "us"). By using the site you agree to these terms. If you don't agree, please don't use it.

1. The service

TailNav shows aircraft positions and flight information gathered by a network of ADS-B and MLAT receivers, combined with information from public registers and other sources. The live map is free to view without an account. We may add, change or remove features at any time.

2. Not for navigation or safety

Positions are received from the ground and can be delayed, incomplete or wrong. Routes, schedules, aircraft details and photos come from third-party sources and may be out of date. Don't use TailNav for navigation, flight planning, air traffic control, search and rescue or any purpose where an error could put someone at risk.

3. Accounts

• You must be 13 or over to create an account.
• One account per person. Give us a real email address and keep it up to date.
• Keep your password and feeder keys private. You're responsible for anything done with them.
• Tell us straight away at privacy@tailnav.com if you think someone else has access to your account.

4. Acceptable use

You may use TailNav for personal, non-commercial purposes. You must not:

• access the site with scrapers, bots or other automated tools, or collect data from it in bulk, except through an API we provide for that purpose and under its terms
• copy, resell, republish or build a competing service from data taken from the site
• interfere with the site, test its security without our written permission, or try to get round rate limits or restrictions
• use the site to harass, stalk or track a person, or for anything unlawful
• frame the site or present our content as your own

If you'd like to use TailNav data commercially, get in touch.

5. Feeding data

If you connect a receiver ("station") to TailNav:

• You must own or have permission to use the receiver, and only send data it has genuinely received. Don't send replayed, copied, generated or altered data, or data taken from another network.
• The location you give for each station must be accurate to within a few hundred metres. We need it to check your data and calculate MLAT positions. We won't publish it exactly.
• You give us a worldwide, non-exclusive, royalty-free, perpetual licence to use, combine, store, display and share the data your station sends, including in products we offer. You can still share your data with any other network.
• You can stop feeding at any time by disconnecting your receiver or removing the station. Data already received stays part of the service.
• Our feeder software runs on your own equipment. Read any command before you run it. We aren't responsible for damage to your equipment or data, or for your internet or electricity costs.

6. TailTokens

• TailTokens are the reward points of TailNav. Stations earn them for data that passes our checks. Rates and checks are described on the feeding page and may change.
• New TailTokens are held for 14 days while we check the data before you can spend them.
• We may withhold, reverse or cancel TailTokens, and suspend stations or accounts, if we reasonably believe data has been faked, a station's location is wrong, or these terms have been broken.
• TailTokens have no cash value. They can't be sold, transferred, exchanged for money or combined between accounts, and they are not property or a financial product.
• If someone joins with your invite link, you both get bonus TailTokens once their station passes our checks and their first TailTokens are confirmed. Invites between accounts on the same internet connection, or between accounts of the same person, don't qualify, and there is a monthly limit.
• TailTokens are lost when an account is closed. If we end the TailTokens scheme, we'll give at least 30 days' notice so you can spend them.

7. Aircraft owners and operators

If you own or operate an aircraft and want its details limited or hidden, see the privacy policy or email privacy@tailnav.com.

8. Our content and other people's

The site's design, software, text, logo and the combined database of flights and aircraft belong to us or our licensors. Aircraft photos belong to their photographers and are shown under the licence each one gives. Map data is © OpenStreetMap contributors. Nothing in these terms gives you rights to our name or logo.

9. Availability

We work to keep TailNav running but don't promise it will always be available, complete or free of errors. We may suspend it for maintenance or if something goes wrong.

10. Our liability

The site is provided free of charge "as is". To the extent the law allows, we aren't liable for any indirect or consequential loss, loss of profit, revenue, data or opportunity, or for any loss caused by relying on information shown on the site. Our total liability to you for anything arising from your use of the site is limited to £50.

Nothing in these terms limits liability for death or personal injury caused by negligence, for fraud, or for anything else that can't be limited by law, and nothing affects your statutory rights as a consumer.

11. Suspension and closing accounts

You can close your account at any time from your account page. We may suspend or close an account, or block access to the site, if these terms are broken or to protect the service or other users. Where reasonable we'll tell you why.

12. Changes to these terms

We may update these terms. The date at the top shows when they last changed, and if a change is significant we'll email account holders before it takes effect. Continuing to use the site after that means you accept the new terms.

13. Law

These terms are governed by the law of England and Wales, and the courts of England and Wales have jurisdiction. If you live elsewhere in the UK, you may also bring proceedings in your local courts.
