Privacy Policy
Effective date: 2026-09-10 · Last updated: 2026-09-10
Summary
- All tools run 100% on your device. We do not collect, log, or transmit the data you process.
- We use Cloudflare Web Analytics (no cookies, no personal identifiers) to count page views.
- We set only strictly necessary cookies (consent state) by default.
- Fonts and code libraries are served from our own domain — no third-party CDN receives your IP address.
- We do not sell or share your personal information.
Information collected
None of the data you submit to our tools leaves your browser. We have no server-side processing for tool inputs. There are no accounts, no sign-up and no user profiles.
Analytics
We use Cloudflare Web Analytics, which is cookieless and aggregated. It does not fingerprint visitors, does not track you across sites, and does not build a profile of you. It reports only aggregate metrics such as page views and referrers.
Cookies and local storage
We do not set advertising or tracking cookies. We store a single item in your browser's local storage to remember that you have dismissed the consent notice, and one to remember your light/dark theme preference. Both stay on your device and are never transmitted to us.
Third-party requests
Loading an asset from a third-party CDN discloses your IP address to that provider. We avoid this wherever possible:
- Fonts — Geist and Geist Mono are self-hosted from this domain. We do not use Google Fonts or any other font CDN.
- JavaScript libraries — bundled or self-hosted; none are fetched from a public CDN at runtime.
- Cloudflare Web Analytics — the one external request, described above.
See Licenses & Third-Party Notices for the full attribution list.
Where data is processed
The site is hosted on Cloudflare Pages. Cloudflare is a US-headquartered provider, so serving a page involves processing connection metadata (including your IP address) on infrastructure that may be located outside your country. For transfers out of the EEA/UK we rely on Cloudflare's data processing addendum incorporating the European Commission's Standard Contractual Clauses, together with the technical measures described above. We do not sell personal data and do not use it for advertising.
Your rights
If you are in the European Economic Area, the UK or Switzerland, you have the right to access, rectify or erase your personal data, to restrict or object to processing, and to data portability. If you are a California resident, you have the right to know what personal information is collected and to opt out of its sale or sharing — we do neither. Because we hold no personal data about you beyond aggregate analytics, most requests resolve to confirming we hold nothing. You may contact us at any time to exercise these rights, and you may lodge a complaint with your local supervisory authority.
Children
This site is a developer tool aimed at a professional audience and is not directed at children under 16.
Changes to this policy
If we change this policy we will update the "Last updated" date above. Material changes will be noted on the homepage.
