Privacy Policy

Effective Date: November 11, 2026 · Publisher: Seventh Domain (hello@seventhdomain.in)

1. Zero-Server / Local-First Data Guarantee

Marginalia operates with zero backend servers owned by Seventh Domain. All sticky note content, URLs, coordinates, and preferences are stored 100% locally on the user's device via Chrome's chrome.storage.local API and (if enabled by the user) written directly to a user-selected local folder on their hard drive via the browser's native FileSystemAccess API. Seventh Domain never reads, transmits, sells, or stores user notes on any external server.

2. Exact Chrome Permission Disclosures

3. Third-Party Payment & License Verification (Polar.sh)

If a user purchases the optional $19 Lifetime Studio Pass, checkout is processed securely by Polar.sh (Merchant of Record). When activating a license key inside the extension, the extension sends only the license key string and an anonymous browser instance label to https://api.polar.sh/v1/customer-portal/license-keys/ to verify validity.

4. Google Chrome Web Store "Limited Use" Disclosure

"The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements."
