1. Google AdSense & Advertising Cookie Disclosures

Mandatory Google AdSense Partner Disclosures:

Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to our website or other websites across the Internet.
Google's use of advertising cookies enables it and its partners to serve personalized and non-personalized advertisements to your device based on your browsing history on this site and other websites.
Users may opt out of personalized advertising at any time by visiting Google Ads Settings.
Alternatively, you can opt out of a third-party vendor's use of cookies for personalized advertising by visiting the Network Advertising Initiative opt-out page at www.aboutads.info.

2. Information We Collect

We believe in data minimization. When you interact with our website and tools, we collect only the information necessary to provide high-quality services:

Voluntary Account & Transaction Information: When you purchase an Ed25519 Capability Passkey or license via Stripe, our payment processor collects payment information under PCI-DSS compliance. We receive transaction status, email addresses for license delivery, and timestamp records.
Interactive Tool Usage: Prompts entered into PromptSmith AI or our in-browser AST validators are processed locally in your client environment or through zero-retention stateless API gateways. We do not store, catalog, or train models on user prompt text.
Log Files & Technical Telemetry: Like most standard web servers, we maintain server logs including IP addresses, browser user-agent strings, referral sources, and visit timestamps to prevent denial-of-service attacks and ensure infrastructure stability.

3. How We Use Information

We use the collected information exclusively to:

Operate, maintain, and enhance the performance of bartholomew.info and associated developer tools.
Deliver cryptographically signed Ed25519 clearance tokens and passkey licenses.
Detect, investigate, and prevent unauthorized security breaches, fraudulent activity, and abuse of API services.
Serve relevant contextual advertisements in accordance with Google AdSense program policies.

4. Cookies and Web Beacons

bartholomew.info uses standard cookies, local storage, and session tokens to preserve user preferences (such as light/dark mode and screen companion positioning) and to measure website traffic. Third-party advertising partners (including Google) may place and read cookies on your browser or use web beacons to collect information as a result of ad serving on this website.

5. CCPA & California Consumer Privacy Rights

Under the California Consumer Privacy Act (CCPA), California residents have the right to request disclosure of the categories and specific pieces of personal information collected, request deletion of personal information, and opt out of the sale or sharing of personal information. Bartholomew does not sell your personal information to third parties. To exercise your privacy rights, contact us at privacy@bartholomew.info.

6. GDPR Compliance & European User Rights

If you are located within the European Economic Area (EEA) or the United Kingdom, you possess statutory rights under the General Data Protection Regulation (GDPR), including rights of access, rectification, erasure, restriction of processing, data portability, and the right to object to automated processing. Our lawful basis for collecting transaction and diagnostic telemetry is our legitimate interest in providing reliable developer tooling and contractual necessity for passkey delivery.

7. Data Security & Retention

We employ robust cryptographic security measures, including HTTPS encryption in transit, strict access control, and automated AST inspection to safeguard all server environments. Payment data is processed entirely by Stripe under Level 1 PCI-DSS certification.
