Terms of Use

1. Scope

These terms govern the relationship between you and the Service Provider regarding the SeaMemo app and its related services. The app is provided as a commercial service; use is currently free of charge. Our Privacy Policy applies in addition.

2. Rights in the app

Unauthorised copying or modification of the app, any part of it, or our trademarks is strictly prohibited. Attempts to extract the source code, translate the app into other languages or create derivative versions are not permitted. All trademarks, copyrights, database rights and other intellectual property rights related to the app remain the property of the Service Provider.

We are committed to making SeaMemo as useful and efficient as possible. We therefore reserve the right to modify the app or to charge for its services at any time. Any charges for the app or its services will be communicated to you clearly beforehand; features you already use will not be billed retroactively.

3. Account and use

To use the app you must create an account with a valid email address and password. You are responsible for keeping your credentials confidential and for all activity that occurs under your account. Please notify us immediately of any unauthorised use.

You may delete your account at any time through the app's settings. On deletion, your account and all associated data are permanently removed from our servers; the action cannot be undone. Details are on the Delete account page.

We reserve the right to suspend or terminate accounts that violate these terms, applicable law or the rights of third parties.

The app stores and processes personal data you provide in order to deliver the service. It is your responsibility to maintain the security of your phone, your credentials and access to the app. We strongly advise against jailbreaking or rooting your phone – removing the restrictions imposed by your device's official operating system. Such actions could expose your phone to malware, viruses and malicious programs, compromise its security features, and may result in the app not functioning correctly or at all.

4. Your content

Trips, journal entries, photos, voice memos and other content you add to the app remain yours. You grant us a non-exclusive, worldwide, royalty-free licence to store, process and display that content within the app, solely for the purpose of providing the service to you and the people you choose to share with.

You represent and warrant that you have the right to share any content you upload and that it infringes no third-party rights and no applicable law. You are solely responsible for the content you create and share through the app.

5. Important safety notice

The sea-miles certificates SeaMemo produces are likewise a documentation aid based on your GPS recording. Whether a certificate is accepted in an individual case is decided solely by the relevant examination board or authority; we cannot guarantee acceptance.

6. Availability and connectivity

Some functions of the app require an active internet connection to sync data – via Wi-Fi or your mobile network provider. We cannot be held responsible if the app does not function at full capacity because Wi-Fi is unavailable or you have exhausted your data allowance.

If you use the app outside a Wi-Fi area, your mobile network provider's agreement terms still apply. You may therefore incur charges from your provider for data usage, or other third-party charges, including roaming data charges if you use the app outside your home territory without disabling data roaming. By using the app you accept responsibility for such charges. If you are not the bill payer for the device you use, we assume you have obtained the bill payer's permission.

Similarly, we cannot assume responsibility for every situation in which you use the app. Keeping your device charged, for example, is your responsibility. If your device runs out of battery and you cannot access the service, that is not attributable to us.

While we strive to keep the app updated and accurate at all times, we rely in part on third parties to supply information (map or weather data, for example). We accept no liability for any loss, direct or indirect, that you experience as a result of relying entirely on that functionality.

7. Liability

To the maximum extent permitted by applicable law, we shall not be liable for any direct, indirect, incidental, special, consequential or punitive damages, including but not limited to personal injury, property damage, loss of data or interruption of service, arising out of or in connection with your use of the app.

This does not affect liability for intent or gross negligence, for damage arising from injury to life, body or health, or under mandatory statutory provisions such as product liability law. Mandatory consumer rights in your country of residence are not restricted by these terms.

8. Changes to these terms

We may update these terms from time to time. The current version always lives on this page; material changes will additionally be announced in the app. Please review this page occasionally. These terms apply in this version as of 14 May 2026.
