Privacy Policy

Last updated: March 30, 2026

Introduction

Brainstem Design Insights ("the app") is a personal tool that connects to the Pinterest API to help the user search and browse their own Pinterest boards and pins. This policy describes how the app collects, uses, and protects information accessed through the Pinterest API.

Information We Access

When you authorize the app with your Pinterest account, we access the following data through the Pinterest API:

  • Board information — Board names, descriptions, and metadata from your Pinterest account

  • Pin information — Pin titles, descriptions, image URLs, source links, and board assignments

  • Account profile — Your Pinterest username and account ID, used solely for authentication

We only access data from the authenticated user's own account. We do not access data from other Pinterest users.

How We Use Your Information

Your Pinterest data is used exclusively to:

  • Display and search your boards and pins within the app

  • Help you identify design patterns and style preferences across your saved pins

We do not use your data for advertising, analytics, model training, or any purpose beyond the functionality described above.

Read-Only Access

This app operates in a strictly read-only capacity. We do not create, modify, or delete any pins, boards, or other content on your Pinterest account. We do not take any actions on your behalf.

Data Storage

Pinterest data is accessed via the Pinterest API at the time of use. OAuth access tokens are stored locally on your device and are not transmitted to third-party servers.

Data Sharing

We do not sell, rent, or share your Pinterest data with any third party. Your data is only accessed by you through the app and by Pinterest as the API provider (subject to Pinterest's Privacy Policy).

Your Controls

  • Revoke access at any time — Remove the app's access from your Pinterest security settings

  • Data deletion — When you revoke access, the app can no longer access any of your Pinterest data. Locally stored tokens are invalidated.

Children's Privacy

This app is not intended for use by anyone under the age of 13. We do not knowingly collect personal information from children under 13.

Third-Party Disclaimer

This application is not affiliated with, endorsed by, or sponsored by Pinterest, Inc. Pinterest is a trademark of Pinterest, Inc. Our use of the Pinterest API is governed by the Pinterest Developer Terms of Service.

Changes to This Policy

We may update this policy from time to time. Changes will be posted on this page with an updated date.
