Terms of Service

These terms govern your use of Tsunava - the mobile app and the services available at tsunava.com. By creating an account or using the app, you agree to these terms. If you do not agree, please do not use the service.

Tsunava helps groups track shared expenses on trips, split costs, and settle balances. It is a record-keeping tool: Tsunava does not hold, transfer, or process money between users. Settling a balance in the app records the payment; the actual transfer of money happens outside Tsunava, between you and your friends.

Balances and conversions are calculated carefully, but exchange rates come from third-party sources and are indicative. You are responsible for verifying amounts before making real payments based on them.

You need an account to use Tsunava. You are responsible for the activity on your account and for keeping your sign-in method secure. You must provide accurate information and be at least 13 years old (or the minimum age in your jurisdiction).

On the free plan you can own one active trip at a time; joining trips created by others is unlimited and free. Tsunava Pro is a one-time in-app purchase that removes the active trip limit permanently. It is not a subscription and does not renew.

Purchases are processed by Apple or Google under their store terms, and refunds are handled through their standard policies. Your unlock can be restored on any device signed into the same store account.

The trips, expenses, and other content you add remain yours. By adding content to a trip you grant us the license needed to store it, sync it, and display it to the other members of that trip - that is what the service does. Members of a trip can see that trip's expenses and balances; invite links grant access to anyone who has them.

You agree not to:

• use the service for anything unlawful, deceptive, or fraudulent;
• attempt to gain unauthorized access to accounts, trips, or our systems;
• interfere with or disrupt the service, or circumvent its limits;
• harass or harm other users.

We may suspend or terminate accounts that violate these terms.

You can stop using Tsunava and delete your account at any time from the Profile screen in the app. Deleting your account permanently removes your account and the trips you own. Expenses you added to other people's trips remain part of those trips' shared records.

Tsunava is provided "as is" and "as available". We work hard to keep it reliable, including offline, but we cannot guarantee the service will be uninterrupted or error-free. To the maximum extent permitted by law, we disclaim all warranties, and our total liability for any claim arising from the service is limited to the amount you paid us in the twelve months before the claim.

We may update these terms as the service evolves. If we make material changes we will update the date above and, where appropriate, notify you in the app. Continuing to use Tsunava after changes take effect means you accept the updated terms.
