Terms of Use
Plain terms for using Vessel. By creating a vessel you agree to these.
Last updated September 2026.
The service
Vessel is a private app for two people to reflect and stay connected. It is offered as-is, without warranties, and may change, pause, or end. We will give notice before any planned shutdown and let you export your data.
Your account
Keep your login details safe; you are responsible for activity on your seat. One vessel is meant for one couple. Vessel is for adults.
Your content
Whatever you write and upload stays yours. You give us only the permission needed to store it and show it to you and your partner so the app can work. We do not use your content to train models, advertise, or share with third parties.
Acceptable use
Use Vessel for your own relationship. Do not upload unlawful content, impersonate someone, or try to access another couple's vessel or break the service. We may suspend or remove a vessel that is used abusively.
Not medical advice
Cycle tracking and the daily reading are for reflection only. They are not medical, legal, or relationship advice, and not a method of contraception. Use your own judgment and consult a professional when it matters.
Ending it
You can delete your vessel and both accounts at any time in Settings. To the extent the law allows, Vessel and its maker are not liable for indirect or incidental losses arising from use of the app.
