Privacy Policy

Last updated: 15 November 2026

1. Who we are

This website, Mailsinger (mailsinger.com), is operated by Mailsinger ("we", "us", "our") from India. We are responsible for the personal information described in this policy. You can contact us at hello@mailsinger.com.

2. Information we do not collect

The email signature generator and the newsletter builder work entirely in your web browser. The names, job titles, phone numbers, email addresses, text, designs and images you enter are processed and saved only on your own device (in your browser's local storage and IndexedDB) so your work is there when you come back. They are not uploaded to our servers, and we cannot see them. You can delete them at any time by clearing this site's data in your browser, or with the reset option in each builder.

We do not offer accounts, so we do not collect passwords or profile information.

3. Information collected automatically

Hosting and security (Cloudflare)

The site is hosted on Cloudflare. To deliver pages and protect the site from abuse, Cloudflare processes technical information such as your IP address, browser type, the page requested and the time of the request, and may keep short-lived security logs. See Cloudflare's privacy policy.

Analytics (Google Analytics)

We use Google Analytics 4 to understand how visitors use the site, so we can improve the tools and content. It collects information such as pages viewed, how you arrived (for example from a search engine), approximate location (country or city, derived from your IP address), device and browser type, and how you interact with the site. We also record which tool actions are used, for example copying a signature, downloading a newsletter, choosing a template or clicking a link to a partner. These events never include the content you type into the builders.

Google Analytics uses cookies (see our Cookie Policy). Google may process this data on servers outside your country. Google Analytics keeps event-level data for 2 months (the standard setting); aggregated reports are kept longer. You can opt out with the Google Analytics opt-out browser add-on.

Advertising (Google AdSense)

We show ads served by Google AdSense. Google and its partners use cookies and similar technologies to show ads, limit how often you see the same ad, measure ad performance and prevent fraud. Where you have agreed (or where consent is not required by law), ads may be personalised based on your visits to this and other websites. You can control personalised advertising in Google's Ad Settings, and learn more at How Google uses information from sites that use its services. Some third-party ad vendors may also use cookies; you can opt out of many of them at aboutads.info or youronlinechoices.eu.

Fonts (Google Fonts)

Pages load the Inter font from Google Fonts, so your browser connects to Google's servers and Google receives your IP address. Google states it does not use this to profile you.

4. Information you give us

If you email us, we receive your email address, your message and anything you attach. Messages to hello@mailsinger.com are forwarded to our inbox by Cloudflare Email Routing. We use them only to reply and to keep a record of the conversation.

5. Affiliate links and partner websites

Some links to email platforms and other tools are affiliate links. When you click one, the partner's website may set its own cookies to record that you came from us, so we can earn a commission if you sign up. Partner websites have their own privacy policies, which we do not control. See our Affiliate Disclosure.

6. Why we use your information (legal bases)

• To run and secure the site (hosting, security logs): our legitimate interest in providing a working, safe website.
• Analytics and advertising cookies: your consent, where the law requires it (for example in the EEA, UK and Switzerland). Elsewhere, our legitimate interest in understanding usage and funding the free tools through ads.
• Replying to your emails: our legitimate interest in answering you, or taking steps you ask for.
• Legal obligations: where we must keep or disclose information by law.

Under India's Digital Personal Data Protection Act, 2023, we process personal data for the purposes above with your consent or for legitimate uses permitted by the Act.

7. Who we share information with

We share information only with service providers that help us run the site, mainly Cloudflare (hosting, email forwarding) and Google (analytics, advertising, fonts), and when required by law or to protect our rights. We do not sell personal information for money.

US state privacy laws: advertising cookies may count as "sharing" personal information for cross-context behavioural advertising under some US state laws (such as California's). You can opt out by declining personalised ads in the consent message where shown, through Google's Ad Settings, or by turning on Global Privacy Control in your browser.

8. International transfers

Our service providers may process information in countries other than yours, including the United States. Where required, they use safeguards recognised by law, such as standard contractual clauses.

9. How long we keep information

• Your designs and settings: on your device until you delete them. We never hold a copy.
• Google Analytics: event-level data for 2 months; aggregated reports longer.
• Advertising and analytics cookies: see the durations in our Cookie Policy.
• Emails you send us: as long as needed to deal with your message, and then for a reasonable period for our records.

10. Your rights

Depending on where you live, you may have the right to:

• access the personal information we hold about you, and get a copy;
• correct information that is wrong or incomplete;
• ask us to delete your information;
• object to or restrict certain processing, including for direct marketing;
• withdraw consent at any time (this does not affect processing before you withdrew it);
• data portability;
• under India's DPDP Act, have your grievances addressed and nominate another person to exercise your rights if you die or become unable to;
• complain to your data protection authority (for example, in India the Data Protection Board of India, in the UK the ICO, or your local authority in the EU).

Because we do not run accounts and the builders keep your content on your device, we usually hold very little information that identifies you. Most analytics and advertising data is held by Google; you can manage it through the links above. To make a request, email hello@mailsinger.com. We will reply within 30 days. We may need to ask for information to confirm the request is yours.

Grievances: for any concern about how we handle personal data, including under India's DPDP Act, contact our grievance contact at hello@mailsinger.com.

11. Your choices

• Cookie settings: change your consent at any time with the Cookie settings link in the footer (shown where consent applies).
• Browser controls: block or delete cookies in your browser settings.
• Saved designs: clear this site's data in your browser to remove them.
• Analytics: install the Google Analytics opt-out add-on.

12. Children

The site is not directed at children, and we do not knowingly collect personal information from anyone under 18. If you believe a child has sent us personal information, contact us and we will delete it.

13. Security

The site is served only over encrypted HTTPS connections. Because your designs never leave your device, they cannot be exposed by a breach of our systems. No method of transmission or storage is completely secure, but we use reputable providers and keep the information we handle to a minimum.

14. Changes to this policy

We may update this policy when the site or the law changes. The "last updated" date at the top shows the latest version. Significant changes will be highlighted on this page.
