Privacy Policy

Tsunava is a group expense tracker for trips, available as a mobile app and at tsunava.com. This policy explains what data we collect, why we collect it, and the choices you have. The short version: we collect what is needed to run the service, we do not sell your data, and you can delete your account and its data at any time.

Account information. When you sign up we collect your name, email address, and profile picture. Authentication is handled by our sign-in provider, Clerk, which processes your credentials on our behalf.

Trip and expense data. The trips, expenses, participants, and settlements you create are stored on our servers so they can sync across devices and be shared with the members of your trips. Guest participants you add (people without an account) exist only as a name inside your trip.

Purchase information. If you buy the Pro unlock, the purchase is processed by Apple or Google and managed through RevenueCat. We receive a confirmation of your entitlement, not your payment details. We never see your card number.

Diagnostics. We use Sentry to collect crash reports and error diagnostics so we can fix problems. These reports may include device model, operating system version, and the state of the app at the time of the error.

Website analytics. The tsunava.com website uses Google Analytics to count visits and see which pages people use. We remove the private parts of a web address before it is sent - invite links and trip identifiers are replaced with a placeholder, so Google never receives them. The mobile app does not use Google Analytics.

Support messages. If you contact us through the app or the website, we keep your message and email address so we can reply.

We do not collect your precise location, your contacts, or advertising identifiers, and we do not show ads. Exchange rates are fetched from a public rates service without sending any of your personal data along with the request.

We use the data above to:

• provide the service - syncing trips, splitting expenses, settling balances;
• share trip data with the other members of trips you join or create;
• verify your Pro unlock across your devices;
• diagnose and fix crashes and bugs;
• respond to your support requests.

We do not sell your personal data or share it with third parties for advertising.

Trip data is shared with the people in that trip: every member of a trip can see its expenses, who paid, and the resulting balances. Invite links grant access to the trip they belong to, so share them only with people you want in the trip.

We rely on a small number of processors to run Tsunava: Clerk (authentication), RevenueCat (purchase management), Apple and Google (payment processing), Sentry (crash reporting), Google Analytics (website statistics), and our hosting providers. Each receives only the data needed for its function.

Your data is kept for as long as your account exists. You can delete your account from the Profile screen in the app, which permanently removes your account and the trips you own. Expenses you added to trips owned by others remain visible to those trips' members, since they are part of the group's shared records.

Depending on where you live, you may have the right to access, correct, export, or delete your personal data, and to object to or restrict certain processing. To exercise any of these rights, contact us at the address below and we will respond within the timeframe required by applicable law.

Tsunava is not directed at children under 13 (or the equivalent minimum age in your jurisdiction), and we do not knowingly collect data from them.

If we make material changes to this policy we will update the date above and, where appropriate, notify you in the app.
