Kongvene Privacy Policy

Effective Date: July 27, 2026

CircleRootTech LLC ("CircleRootTech LLC," "we," "us," or "our") operates Kongvene, a mobile application that helps mahjong circles schedule play days, coordinate hosting, and keep informal records of shared dues (the "App"). This Privacy Policy explains what information we collect, how we use it, and the choices you have. By creating an account or otherwise using the App, you agree to the practices described here.

1. Information We Collect

Account Information

When you create an account, we collect your email address and the display name you choose. This information is used to identify you within your circles and to let other members recognize you.

Circle and Activity Information

The App stores the information you and your circle members generate while using it, including:

• Circles you create or join, and their invite codes
• Play day dates, notes, and RSVP status (seated at a table, on the subs list, etc.)
• Host rotation order and whose turn it is to host
• Dues amounts and paid/unpaid status that you or your circle organizer enter
• A Venmo or Cash App username, if an organizer chooses to add one to their circle settings

Information We Do Not Collect

We do not collect or have access to any payment card numbers, bank account details, or Venmo/Cash App account credentials. Dues amounts and paid/unpaid status shown in the App are self-reported or organizer-reported records only — see Section 5 for more detail on how this works.

Automatically Collected Information

Our infrastructure provider (Firebase, operated by Google) may automatically log limited technical information, such as device type and crash diagnostics, to help us keep the App running reliably.

2. How We Use Information

We use the information described above to:

• Operate the core features of the App (scheduling, RSVPs, host rotation, dues tracking)
• Let circle members see who is participating in a play day and who is hosting
• Maintain the security of accounts and circles
• Respond to support requests
• Improve and maintain the App

We do not use your information for advertising, and we do not sell your personal information to third parties.

3. How Information Is Shared

Information within a circle (such as your display name, RSVP status, and dues status) is visible to other members of that circle, and in some cases only to the circle organizer, consistent with how each feature is described in the App.

We share information with the following categories of third parties only as necessary to operate the App:

• Firebase/Google Cloud — our hosting and database provider, which stores App data on our behalf

We do not share your information with Venmo, Cash App, or any other payment service. When you tap a "Pay via Venmo" button in the App, your device opens a link directly to Venmo using information already stored in your circle (the organizer's Venmo username and a dues amount) — this happens on your own device, not through our servers, and we do not receive any information back from Venmo about whether a payment was completed.

4. Your Choices

• You can update your display name and circle settings at any time within the App.
• You can leave a circle at any time.
• You can delete your account at any time from Settings. This permanently removes your account. Circles you created remain available to their other members, consistent with the confirmation shown in the App when you delete your account.

5. Dues Tracking Is Not a Payment Service

Kongvene is a coordination and record-keeping tool, not a payment processor. Dues amounts and "paid"/"unpaid" statuses shown in the App reflect what a circle organizer or member has manually entered — the App does not verify that any money has actually changed hands, and does not process, hold, or transmit funds. Any actual payment happens entirely within Venmo, Cash App, or another service the members choose to use, outside of the App.

6. Data Security

We use commercially reasonable safeguards, including database access rules, to protect the information stored in the App. No method of storage or transmission is completely secure, and we cannot guarantee absolute security.

7. Children's Privacy

Kongvene is not directed at children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us at thecircleroottechllc@gmail.com so we can remove it.

8. Changes to This Policy

We may update this Privacy Policy from time to time. If we make material changes, we will update the effective date at the top of this document. Continued use of the App after changes take effect means you accept the revised policy.
