Privacy

Legal identity not yet registered. This product is operated by an individual who has not yet registered a legal entity, registered address, or jurisdiction for this business. No company name, postal address, or registered contact is available. The operator must supply these details before this policy can bind anyone. Until then, this document states the data practices of the service as it currently operates.

Data collected by this service

Previewcard does not collect, store, or share any personal data. The service operates entirely in the browser and on a stateless Cloudflare Worker. When you paste a URL and click Check, the Worker fetches that URL, parses its HTML for meta tags, fetches any referenced images to verify dimensions, and returns the results to your browser. The results exist only in your browser's memory — they are not saved, logged, or transmitted anywhere else.

URLs you submit

The URLs you submit to the checker are processed only for the purpose of returning the diagnostic report. They are not stored, indexed, cached, or logged after the response is sent. No database, queue, or long-term storage exists on the server side.

Fetched page content

The HTML content of pages you check is fetched and parsed in the Worker's memory during your request. It is discarded immediately after the response is returned. Previewcard does not cache pages, archive content, or extract data beyond the meta tags needed for the social preview report.

Cookies and tracking

This site does not set cookies, use fingerprinting, load third-party tracking scripts, or employ analytics services. No personal identifiers are collected at any point.

Cloudflare infrastructure

This site is served through Cloudflare's content delivery network. Cloudflare may process standard HTTP request metadata (IP address, User-Agent, request timestamps) as part of its normal operation. Their handling of this data is governed by Cloudflare's Privacy Policy. Previewcard does not access or store any of this infrastructure-level data.
