Privacy

Short version: what you render is not stored or logged.

The chart maker, card maker, Markdown and invoice previews run in your browser.
When you download a PNG or make a PDF or screenshot, your input is sent to the Render API once, the file is streamed back, and nothing is kept.
For the free limits, we keep per-day counters keyed by a salted SHA-256 hash of your IP address. The raw address isn't stored.
Chart and card image URLs contain their data in the link. Anyone with the link can see it, and Cloudflare caches the image.
PDFs and screenshots are rendered by Cloudflare Browser Rendering. Cloudflare processes requests as our infrastructure provider.
There are no ads, no analytics cookies and no tracking pixels.
