Resonance Handpan Reporting App - Privacy Policy

Last updated: 27 September 2026

This privacy policy explains how the Resonance Handpan reporting app (the "app") collects, uses, stores and protects data, including data received from Google APIs. The app is a private tool used only by the owner of Resonance Handpan to measure the shop's advertising. It is not offered to the public.

1. Information the app accesses

With the explicit permission of the Google account owner, given through Google's OAuth consent screen, the app uses the Google Ads API (scope https://www.googleapis.com/auth/adwords) to read the following data of the Resonance Handpan Google Ads account:

  • campaign, ad group, keyword and ad settings;
  • performance metrics: impressions, clicks, costs, conversions and conversion values;
  • search terms that triggered the shop's ads;
  • keyword search volumes from the Keyword Planner.

The app also reads the orders and products of the Resonance Handpan online store to calculate margins. It does not access Gmail, Google Drive, contacts or any other Google service.

2. How the information is used

The data is used only to show the owner of Resonance Handpan reports and recommendations about the shop's advertising: sales, margins, campaign results and market sizes. It is not used for any other purpose, and it is never used to serve, target or personalize advertising.

3. How the information is stored and protected

The app runs on the owner's computer. The data is stored in a local database on that computer. The access tokens are stored in a local file that only the computer's owner can read. Data travels between the computer and Google over encrypted HTTPS connections. No data is uploaded to a third-party server.

4. Sharing and disclosure

Google user data is never sold, rented, shared or transferred to third parties. The only exception would be a legal obligation, such as a valid court order.

5. Google API Services User Data Policy

The app's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

6. Retention and deletion

The data is kept only as long as it is needed for the owner's reports. The owner can delete the local data at any time. Access to the Google Ads account can be revoked at any time at https://myaccount.google.com/permissions; the app then stops reading any new data.

7. Changes to this policy

Any change to this policy will be published on this page with a new date.
