Privacy Policy

Pin Library Organizer — a single-user Pinterest organization tool by Yvan Castonguay.
Effective date: October 3, 2026.

1. What this tool is

Pin Library Organizer is a personal productivity application used exclusively by its owner (Yvan Castonguay) to organize their own Pinterest account. It is not offered to the public and has no other users. It connects to Pinterest through the official Pinterest API (v5) using OAuth 2.0.

2. Data we access

With the owner's explicit OAuth authorization, the application accesses the owner's own Pinterest data:

• Boards: board names, descriptions, privacy settings, and pin counts.
• Pins: pin titles, descriptions, destination links, board assignments, and image URLs.
• Account: basic profile information needed to confirm the authorized account identity.

The application does not access any other person's data, and performs no automated posting, following, commenting, messaging, or advertising activity.

3. How data is used and stored

• Organization only. Data is used solely to inventory the owner's library, identify misfiled or duplicate pins, and — only after the owner's explicit confirmation of each planned change — move pins between the owner's own boards.
• Transient image processing. To detect duplicates, pin images are downloaded, converted into compact perceptual hashes, and then immediately discarded. Full image files are never retained. Only the hashes (short numeric fingerprints) are kept, and only for duplicate detection.
• Minimal retention. Board and pin metadata needed for the organization task is kept only for the duration of the task. OAuth tokens are stored securely and used only to maintain the owner's authorized session; they are never shared.
• No deletion. The application never permanently deletes pins or boards. Duplicates are moved to a private holding board for the owner's review.

4. Data sharing

We do not sell, rent, or share your data with any third party. Data accessed through the Pinterest API is used only within this application for the purposes described above. The only external service involved is Pinterest itself, whose own Privacy Policy governs data held on its platform.

5. Data security

Access credentials (OAuth tokens, application secrets) are stored in encrypted secure storage and never exposed in logs, messages, or source code. All communication with Pinterest uses encrypted HTTPS connections.

6. Your rights

Because this application serves only its owner, data inquiries are straightforward: the owner may revoke the application's access at any time via Pinterest's authorized-apps settings, which immediately ends all data access. Requests to delete locally retained hashes or metadata are honored promptly.

7. Changes to this policy

If this policy changes materially, the updated policy will be posted at this same address with a revised effective date.
