Privacy Policy

Effective Date: February 18, 2026

1. Overview

thinksn is designed to minimize data collection. We collect only the information necessary to operate the service, generate semantic networks, and provide optional account access.

2. Information We Collect

• Authentication Data: If you choose to sign in, we collect your email address solely to deliver passwordless login links. If you register a Passkey, we store the associated public credential data required for authentication.
• Query & Network Data: We store the queries you submit and the resulting semantic networks, associated with an anonymous or authenticated User ID. Queries are automatically screened by a filter designed to detect and exclude personal or sensitive content. Queries that pass this filter — those that are generic and contain no personal information — may be made publicly accessible as part of thinksn's knowledge base. Queries that do not pass the filter are used only to generate your session's network and are not stored beyond that purpose.
• Technical Data: Limited technical information (such as browser type or device category) may be processed to ensure the application functions correctly.

3. How We Use This Information

• To generate, display, and store semantic networks.
• To provide secure, passwordless authentication.
• To maintain service reliability and prevent abuse.
• To maintain and expand thinksn's public knowledge base, using only generic, non-personal queries that have passed our automated privacy filter.

4. Sponsored Links & External Sites

thinksn may display clearly labeled sponsored or recommended links. We do not run third-party advertising scripts and do not set advertising cookies.

• No behavioral tracking is performed on thinksn.
• We do not share personal data with advertisers.
• If you click a sponsored link, you leave thinksn and are subject to the destination site’s privacy practices.

5. Data Storage & International Transfers

Our servers and databases are located in the United States. By using thinksn, you acknowledge that your information may be processed and stored in the U.S., subject to applicable safeguards.

6. Data Retention & The 30-Day Rule

• Account Data: Email addresses and Passkey credentials are retained until you delete your account.
• Library Data: Networks stored in your personal library are retained as long as they remain associated with your active account.
• Shared & Disassociated Data: If you share a network via a link or remove it from your library, that data is subject to "Natural Expiration." To ensure data minimization, any network that has not been accessed by any user for 30 consecutive days is automatically and permanently deleted from our servers.

7. Your Rights

Regardless of your location, you have the right to access, export, correct, or delete your personal data.

• You may manage or delete private semantic networks from your dashboard.
• You may request a full data export or account deletion via our Contact Page.
• Where applicable, you may lodge a complaint with a data protection authority.

8. Legal Basis for Processing (EEA/UK Users)

For users in the European Economic Area or United Kingdom, thinksn processes query data for the purpose of building a public knowledge base on the basis of legitimate interests. Our filter is the primary safeguard: it is designed to ensure that only non-personal, generic queries are used for this purpose. You have the right to object to this processing by contacting us via our Contact Page.

9. Account & Data Deletion

When you delete your account:

• Your email address and authentication credentials are immediately purged.
• The link between your identity and your generated networks is severed.
• Networks previously in your library enter a "disassociated" state. These networks will remain accessible via their unique links only until they hit the 30-day inactivity threshold, at which point they are permanently deleted.

Note: To exercise data rights tied to your User ID, you must be logged in. For assistance, please contact us.
