Privacy Policy
Effective October 5, 2026
Sigmate (“we”, “us”) is an email signature maker on the web (getsigmate.com) and on iPhone and iPad. This policy explains what we collect and why. The short version: your signature lives in your browser or on your device, we host the images you choose to upload, we keep a server copy of your signature only when you have Pro, and we do not sell or share personal data.
What we collect
- Signature content. The details you type (name, title, phone, links, and so on) are stored in your browser (web) or on your device (app). With Pro, a copy of the signature is also saved on our servers (Cloudflare, United States and global edge locations) so you can restore it on another device. Free signatures are never sent to us.
- Uploaded images (Pro). If you add a headshot, logo or brand photo, the image and the cuts we make from it are uploaded to our servers (Cloudflare R2) so email apps can display them. Each file gets a random, unguessable URL. Anyone who receives your email can view the image at that URL; that is how email images work.
- Signature links (Pro). If you create a signature link, the signature HTML is stored at a random URL so you can open it on another device. Signature links are not indexed by search engines.
- Click analytics (Pro, optional). If you switch on click analytics, links in your signature point to a Sigmate redirect address. When someone taps a link we count the click (which link, which day) and send them straight to your destination. We do not record who clicked, their IP address, or their location; there are no tracking pixels and nothing is placed in the recipient’s inbox.
- Sigmate Assist. When you use the assistant, what you give it (typed text, a website address, an uploaded business card, screenshot or logo) is sent to our servers and to Anthropic’s API to read it and fill in your signature. Anthropic processes it to generate the response and does not use it to train models. We keep a daily usage count per team or address to prevent abuse; we do not keep the conversation. Giving the assistant a website makes our server fetch that site’s public pages once.
- Purchases on the web. Payments are processed by Stripe. We receive your checkout email, the plan you bought and its status so we can unlock Pro and send you a recovery link; Stripe holds your card details under Stripe’s privacy policy. Recovery emails are sent through Resend to the email you used at checkout.
- Purchases in the iOS app. Subscriptions are processed by Apple. Our purchase provider, RevenueCat, receives an anonymous app user ID and your purchase status so we can unlock Pro. We never see your payment details.
- Team links. If your company gives you a team link, the company’s branding and details are prefilled; what you add is stored like any other signature. The company does not see your signature.
- Technical data. Our servers log standard request data (IP address, user agent, timestamps) for security and abuse prevention. Logs are retained for up to 30 days.
What we do not do
- No passwords, no accounts; Pro is tied to your checkout email.
- No advertising SDKs, no third-party ad tracking, no data brokers.
- No tracking pixels in your signature.
- No selling or sharing of personal data.
Your choices
- Remove an image or signature link in the app and it stops being used in new signatures. To have hosted files or your server copy deleted, email support@getsigmate.com with the URL or your checkout email and we delete them within 7 days.
- Clear your browser’s site data or delete the app to remove all locally stored signatures.
- Manage or cancel a web subscription from the app: click your plan badge (for example “Pro · yearly”) to open your Stripe billing portal. Manage App Store subscriptions in your Apple ID settings.
- Do not use the assistant if you prefer that nothing you type is sent to our servers; every field can be filled by hand.
Children
Sigmate is not directed to children under 13 and we do not knowingly collect data from them.
Changes
We will post updates here and change the effective date above.
