Licenses & Third-Party Notices
Last updated: 2026-10-10
This page lists every font, library and service the site relies on, together with its license and where to find the full license text. jsonversal's own assets are self-hosted; the only third party that receives a request at runtime is our advertising partner, described below.
Fonts
This site uses Geist and Geist Mono, served from this domain. The font files are self-hosted — the page does not contact Google Fonts, Adobe Fonts, Bunny Fonts or any other font CDN.
| Asset | Copyright | License | Full text |
|---|---|---|---|
| Geist · Geist Mono | © 2023 Vercel, in collaboration with basement.studio | SIL Open Font License 1.1 | LICENSE-Geist-OFL.txt |
The SIL OFL 1.1 permits commercial use, self-hosting, web embedding and redistribution. It requires that this copyright notice and the license text accompany the fonts, and prohibits selling the fonts on their own.
Third-party code
Every library below is bundled or self-hosted and served from this origin. None of them is fetched from a public CDN at runtime.
| Component | Version | Copyright | License | Full text |
|---|---|---|---|---|
| yaml | 2.5.0 | © Eemeli Aro | ISC | LICENSE-yaml.txt |
| bcryptjs | ^3.0.3 | © Daniel Wirtz | MIT | see package |
| Astro | 4.x | © Astro contributors | MIT | build-time only |
Infrastructure and advertising
| Service | Purpose | Data involved |
|---|---|---|
| Cloudflare Pages | Hosting and content delivery | Connection metadata (IP) processed to serve the request |
| Google AdSense | Advertising — funds the free tools | IP address, page URL, device and browser, and coarse location inferred from IP, used by Google and its partners to serve and measure ads. Never your tool input. |
Cloudflare acts as our hosting provider and Google AdSense as our advertising partner. Ad serving is subject to Google's own privacy policies and to the opt-out links in the Privacy Policy. We do not receive your name, email address, or the contents of anything you enter into a tool.
What this site does and does not send
- No external font CDN — fonts are served from this domain.
- No third-party JavaScript CDN — libraries are bundled or self-hosted.
- No analytics beacon of our own — the site runs no first-party analytics.
- No social widgets and no embedded third-party media.
- Advertising is served by Google AdSense; see the table above for exactly what that involves.
This matters beyond performance: loading an asset from a third-party CDN discloses the visitor's IP address to that provider. Under the GDPR that is a personal-data transfer requiring a legal basis — which is why we keep our own assets self-hosted and limit third-party contact to the advertising we disclose. The tools themselves run entirely in your browser, so the data you paste never leaves your device and is never sent to us, to Google, or to any ad partner.
