Privacy Policy
What SignMyMail does and does not collect. Short version - your signature stays in your browser.
The short version
SignMyMail is a free email signature generator that runs entirely in your browser. The details you type, the photo or logo you upload, and the signature you copy are never sent to us. There is no account, no database of users, and no cookie banner because we set no cookies.
Operator and data controller
SignMyMail is operated by Huihang Zhong (钟汇杭), an individual operator based in mainland China who publishes under the name Andy Chung. He is the service operator and data controller for the limited information described in this policy.
What stays on your device
- Signature details. Name, title, company, contact lines, links, colours, and template choice are saved in your browser's local storage (
localStorage) so the signature is still there when you come back. You can remove it at any time with "Clear all" in the editor or by clearing site data in your browser. - Photos and logos. An uploaded image is cropped and resized on your device and embedded in the signature as data. It is not uploaded to any server. If you paste an image URL instead, the email clients of your recipients load the image from that URL, not from us.
What we do collect
- Anonymous usage statistics. We use a self-hosted instance of Umami, a cookieless analytics tool that does not build personal profiles or store IP addresses. It records page views, page loading performance, and a few whitelisted product events (for example "signature copied" or "template selected") together with the country, browser type, and screen size derived from the request. Any URL query parameters other than attribution parameters (such as
utm_sourceandref) and any URL fragments are removed before sending. Event data never includes the content of your signature. - Cloudflare Web Analytics. Our hosting provider, Cloudflare, provides aggregate performance and traffic metrics. It does not use cookies or track individuals across sites. See Cloudflare's privacy policy.
- Server logs. Cloudflare Workers keeps short-lived request logs (URL, status, timing) for error diagnosis. They are not used to identify individuals.
Images referenced by your signature
Signatures that use social icons reference small image files hosted on this website. When a recipient opens an email containing your signature, their email client may request those icon images from our server. That request contains the recipient's IP address and user agent, as any image request does. We do not use these requests for tracking, do not set cookies, and do not log them beyond the standard short-lived server logs above.
Contact
If you email us, we receive your email address and whatever you write. We use it only to reply. We do not add you to any list.
Third-party services
Your signature may contain links to third-party websites (your own website, LinkedIn, X, and so on). Those sites have their own privacy policies. We have no control over them.
Children
The service is not directed to children under 13 and we knowingly collect no information from them.
Changes
If this policy changes, the new version is posted on this page with an updated date at the top.
