At DKIM Studio, we respect your privacy and are committed to protecting your personal information. This site is deliberately built so that there is very little to protect: the tools run in your browser, and we operate no backend that could store what you check.
Data We Collect
Domains and Selectors You Check
When you use the DKIM checker or selector finder, the domain and selector you enter are used to build DNS queries. These queries are:
- Sent directly from your browser to Google Public DNS over HTTPS (
dns.google) — they never pass through our servers - Not stored by us — we have no server-side component that could receive them
- Not logged or retained by us in any form
- Only used to perform the check you asked for
Google processes those DNS queries as the resolver operator, under its own Google Public DNS privacy policy.
Generated Keys
The record generator creates key pairs with your browser's built-in WebCrypto API. Both the public and private keys are generated locally and never leave the page. We cannot see them, we do not transmit them, and we cannot recover them for you — if you lose a private key, generate a new one and rotate.
Automatically Collected Information
dkim.studio runs no analytics and sets no tracking cookies. Our hosting provider may record standard technical logs (IP address, requested URL, browser type) to serve the site and defend against abuse, as virtually all web hosting does.
How We Use Your Data
- Service Provision: to perform the DKIM checks and key generation you request — entirely in your browser
- Security: hosting-level logs may be used to detect and prevent abuse of the site
- Legal Compliance: to comply with applicable laws and regulations
Data Protection
- Encryption — the site and all DNS-over-HTTPS queries are encrypted in transit using HTTPS/TLS.
- No Storage — checks are processed in real time in your browser; nothing you enter is stored by us.
- Local Keys — generated private keys exist only in your browser's memory until you download them.
- Minimal Surface — no accounts, no databases, no analytics scripts.
Third-Party Services
We use the following third-party services:
- Google Public DNS (dns.google): resolves the DNS queries the tools make from your browser
- CDN / Hosting: serves the static site files
These services have their own privacy policies. We encourage you to review them.
Local Storage
DKIM Studio uses your browser's local storage for two small preferences: your theme choice (light or dark) and your result mode (Easy or Tech). These values stay on your device, are not transmitted anywhere, and can be cleared at any time through your browser settings. We set no advertising or analytics cookies.
Your Rights
You have the right to:
- Access information about how your data is used
- Request deletion of any stored personal data (we hold none, but you may always ask)
- Clear the local preferences the site stores in your browser
- Contact us with privacy concerns
