Privacy Policy

Tripeppi Echo Builder — Last updated: July 7, 2026

This Privacy Policy explains what information the Tripeppi Echo Builder ("the App", "we", "us") collects when you use it, how that information is used, and the choices you have. The App is a free, fan-made tool that helps players manage Wuthering Waves echo builds using Google Sheets. The App is operated by Tripeppi ("the operator"), who acts as the data controller.

By signing in and using the App, you agree to this Policy. If you do not agree, please do not use the App.

1. Information we collect

Your Google account email address. When you sign in with Google, we receive your email address so we can identify you and connect you to your own personal copy of the build spreadsheet.
The build data you create. Character builds, echo stats, settings and similar content that you enter are stored in a Google Sheets spreadsheet that is copied to your own Google Drive under your Google account.

We do not collect your Google password (Google handles all authentication), and we do not knowingly collect any other personal information.

2. How we use your information

To identify you and route you to your personal copy of the spreadsheet.
To create, read, edit and display your build data.
To run background calculations (for example echo probability computations) through Google Apps Script.

3. Google API Services and permissions

The App uses Google APIs and requests only the permissions (OAuth scopes) needed to work:

.../auth/spreadsheets — to create, read and edit your personal build spreadsheet.
.../auth/script.scriptapp — to schedule and manage the background processing used to compute your builds.
.../auth/userinfo.email — to read your email address so we can identify you.

Limited Use. Tripeppi Echo Builder's use and transfer of information received from Google APIs to any other app will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

4. Where your data is stored

Your build data lives in a Google Sheets file inside your own Google Drive. We do not operate separate servers or databases and do not keep a copy of your builds outside of Google's infrastructure. Data is processed and stored by Google in accordance with Google's own privacy terms.

5. Data sharing

We do not sell, rent or trade your personal data. We do not share it with third parties for advertising or marketing, and the App does not display third-party ads. Data may only be processed by Google as the underlying platform provider.

6. Data retention and your choices

Your build spreadsheet remains in your Google Drive for as long as you keep it. You can delete it at any time from your Drive.
You can revoke the App's access to your Google account at any time from your Google Account permissions page.

7. Your rights (EU/EEA — GDPR)

If you are located in the European Union or European Economic Area, you have the right to access, rectify, erase, restrict or object to the processing of your personal data, and the right to data portability. Because your data is stored in your own Google Drive, you can exercise most of these rights directly (by viewing, editing or deleting your spreadsheet, and by revoking access). For any other request, contact us using the details below. You also have the right to lodge a complaint with your local data protection authority (in France, the CNIL).

8. Children's privacy

The App is not directed to children under the age of 13 (or the minimum age required in your country), and we do not knowingly collect personal data from them.

9. Changes to this Policy

We may update this Policy from time to time. The "Last updated" date at the top will reflect the latest revision. Continued use of the App after changes take effect constitutes acceptance of the updated Policy.

10. Contact
