These terms apply when you sign in to manta, publish trips or a profile on the web, or use live tracking. Keeping your logbook in the app needs no account and isn't covered here: the app itself is licensed under Apple's standard licence agreement, and purchases like manta Pro are made and billed through the App Store under Apple's terms.
Who we are
manta is run by Funkhaus Creative GmbH, Strandstraße 91, 18055 Rostock, Germany (see the imprint). Questions about these terms: support@sailwithmanta.com.
Your account
An account is free and optional. You need one to publish to the web. You sign in with Apple, Google or a code sent to your e-mail address. There is no password. You must be at least 13 years old to create an account. An account is for one person; keep access to your Apple ID, Google account and mailbox to yourself, because whoever controls them controls your manta account. You can delete your account at any time in the app (Settings → Web profile → Delete account). This removes your profile, your shared trips and their photos from our servers.
Your content
What you publish (trips, tracks, log entries, photos, your profile) stays yours. To show it on the web, you give us a free, non-exclusive, worldwide right to store, copy, resize and display it on share pages, your profile, live views, link previews and the Discover section, for as long as it is published. The right ends when you unpublish the content or delete your account; copies in backups disappear in the normal backup cycle. You decide what you publish. Before publishing, make sure you are allowed to: you need the rights to the photos and texts, and the people shown or named in them should agree to it.
What isn't allowed
We have no tolerance for objectionable content or abusive behaviour. Don't publish or use manta for anything that: • is illegal, or infringes someone else's rights (copyright, trademarks, privacy, personality rights); • is hateful, harassing, threatening, violent, sexually explicit or discriminatory; • shows or names people who haven't agreed to it, or shares other people's personal data; • pretends to be someone else, or another organisation; • is advertising, spam, or has nothing to do with sailing and boating; • interferes with the service: automated scraping, getting around limits, probing for vulnerabilities, or overloading our servers.
Usernames
A username can be changed every 30 days; the old one forwards to the new one for 90 days and is then free again. We may change or take back a username that breaks these terms, infringes a trademark or name, misleads others about who is behind it, or is offensive.
Reports and moderation
If you see content that breaks these terms or the law, send us the link at support@sailwithmanta.com (in English or German). We review every report promptly. We may remove content, make a profile private, or suspend or close an account that breaks these terms or the law. If we do, we tell you why, unless the law doesn't allow it, and you can reply to us at the same address if you think we got it wrong.
Public by design
A shared trip can be seen by anyone who has its link. Public profiles and their trips can also be listed in Discover and found by search engines; you can make your profile private in the app. Live tracking shows your boat's position in near real time to anyone with the link. Think about who you share it with, for example when your home or your boat is unattended.
Not a navigation or safety system
manta is a logbook. Positions, speeds, weather, automatic log entries, trip stories written by AI and certificates are generated from your devices' and your boat's data and from third-party services. They can be incomplete or wrong. Never use manta for navigation, collision avoidance or safety decisions: the skipper stays responsible. We don't check or verify what you record, publish or certify.
Availability and changes to the service
Web sharing is free. We work to keep it running, but we can't promise that it is always available or free of errors. We may change features and set reasonable limits (for example on the number of shared trips or photos). If we ever shut the web service down, we will tell you in good time so that you can save your data. Your logbook in the app is not affected either way.
Liability
We are fully liable for intent and gross negligence, for injury to life, body or health, and under the German Product Liability Act. For slight negligence we are liable only for breaches of obligations that are essential for the service to work and that you may rely on, and then only for the typical, foreseeable damage. Beyond that, our liability is excluded. These limits also apply to our employees and agents.
Changes to these terms
We may update these terms, for example when we add features or the law changes. We will tell you about important changes in the app or by e-mail before they take effect. If you don't agree, you can delete your account at any time.
Law
German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer, you keep the protection of the mandatory laws of the country you live in. We are neither obliged nor willing to take part in dispute-resolution proceedings before a consumer arbitration board (§ 36 VSBG).
