Privacy and cookie policy
Last technically reviewed: July 2026
Mintline uses necessary first-party storage to operate the site. Optional analytics remains disabled until you consent. Advertising storage, ad personalization, and ad user-data consent are always denied by Mintline's Google Consent Mode configuration.
| Cookie or storage | Provider | Purpose | Category | Duration |
|---|---|---|---|---|
| mintline_consent | Mintline | Stores your analytics and preference choices. | Necessary | 1 year |
| better-auth session cookies | Mintline / Better Auth | Keeps your Google-authenticated Mintline session secure. | Necessary | Session policy |
| mintline_analytics_id | Mintline | Random identifier for first-party page-view counts. It is not your Google account ID. | Analytics | 1 year |
| _ga, _ga_* | Google Analytics | Distinguishes browsers and sessions for aggregate product analytics. | Analytics | Up to 2 years |
Necessary storage
Consent storage records your choice. Better Auth uses secure, HTTP-only session cookies after Google sign-in. The theme preference is stored in local storage only after you change the theme. Guest collections and alerts are also stored locally so those features work without an account.
Analytics
If accepted, Mintline records first-party page views using a random browser identifier and may load Google Analytics 4 when a measurement ID is configured. Google receives page URLs, page titles, interaction events, and technical browser information under Google's terms. Mintline does not send names, email addresses, card collection contents, or Google account identifiers to analytics.
Google Analytics is configured without advertising signals or ad personalization and with manual single-page-app page views. Configure the GA4 property's event-data retention to the shortest period appropriate for the business, preferably 14 months or less.
Changing or withdrawing consent
Use “Manage cookie choices” at any time. Withdrawing analytics consent stops future analytics collection, updates Google Consent Mode to denied, and attempts to remove Mintline and Google Analytics cookies from this host. Necessary storage remains active because the site cannot securely provide account and consent features without it.
Third parties and disclosures
Google provides authentication and, after analytics consent, analytics processing. Sponsored eBay links may earn Mintline a commission, but Mintline does not load an eBay marketing pixel. CardSight supplies catalog and pricing data through server-side background jobs and does not receive visitor analytics from the browser.
Contact and legal review
This page documents Mintline's current technical behavior and is not legal advice. Before public launch, the site owner should add a privacy contact address, identify the legal entity and jurisdiction, and have counsel review the policy for every market where Mintline operates.
