Privacy policy

We collect your email when you request a magic link or purchase access. Stripe handles payment details. We receive the payment status and transaction metadata needed to provide the service.

Domains submitted for future lookups may be cached for up to 30 days to make repeated requests faster. Dated editions are read-only public artifacts. LinkCensus does not collect or provide traffic data.

When you create an API key, we store a one-way hash of it, never the key itself, together with its label, its first characters, its scope and tier, and when it was created, first and last used, and revoked. The full key is shown to you once and cannot be shown again. We count admitted API neighborhood lookups per account and calendar month to apply the API allowance.

Before a free key is issued, we record which revision of the terms of service you accepted and which revision of this privacy policy you acknowledged, with the time, and link that record to the keys issued under it. We keep an exact copy of each revision. We use these records to operate and secure your account, to apply the allowance, and to show which terms applied to a key.

Optional Google Analytics loads only after you accept analytics in the consent banner. The consent choice is stored in lc_consent_v1. With consent, campaign details may be kept in lc_attribution_v1 and recorded with relevant product events.

We use lc_token for authentication and the consent and attribution names above. You can withdraw analytics consent by clearing site data in your browser.

We use Stripe for payments, Postmark for transactional email, and hosting providers to operate the service. Account and transaction records are retained as needed for service delivery, security, and legal obligations. We do not sell personal data.

You may ask for access, correction, export, or deletion of personal data by emailing [email protected]. You may also object to optional analytics.

Each edition is an immutable snapshot with its own date. We promise no future edition cadence, and a later edition does not rewrite an earlier one.
