Privacy policy

Effective November 11, 2026

Who we are

This policy covers the MailToChat mobile app and the website mailtochatapp.com ("MailToChat", "we", "us"). Questions about privacy can be sent to support@mailtochatapp.com.

What the app does with your emails

MailToChat only sees text you choose to give it: text you share to the app from another app, or text you paste into it. The app then:

• cleans up that text (removing signatures, earlier replies, images, menus and footers) on your phone;
• shows you the result so you can edit it; and
• when you tap a send button, opens WhatsApp or your phone's Messages app with the text filled in.

For Key points and Full, the email text is not sent to us or to any server we operate. MailToChat never asks for your email password and never signs in to your email account.

AI summaries (iPhone app, optional)

The iPhone app offers an optional AI option. It is used only when you tap it, one email at a time. When you do:

• the cleaned-up text of that email (with its sender name and subject) is sent over an encrypted connection to the MailToChat server, which passes it to our AI provider, Anthropic, to write the summary;
• the MailToChat server does not store or log the email text or the summary. It keeps only a count of how many AI summaries an anonymous app ID has used this month, to apply the free limit, for up to 40 days;
• Anthropic processes the text only to provide the summary. Under its commercial terms it does not use this text to train its models, and it may keep it for a limited time for safety and abuse monitoring, as described in Anthropic's privacy policy.

AI summaries are never used by the Gmail or Outlook add-ons, and never run unless you choose them.

Subscriptions (MailToChat Pro)

MailToChat Pro is bought through Apple. Apple handles payment, and we never see your name, Apple ID, email or card details. To know whether you have Pro, the app uses RevenueCat, a subscription service, which receives an anonymous app ID and your purchase record (product, dates and status) from Apple. See RevenueCat's privacy policy. You can cancel anytime in Settings → Apple ID → Subscriptions.

MailToChat for Gmail

If you install the MailToChat add-on for Gmail, Google asks for your permission to let it read the email you have open. The add-on uses that permission only to show the cleaned-up message while the email is open. It runs inside Google's Apps Script service, does not store your emails, does not send them to any MailToChat server, and cannot read other emails or send email on your behalf. When you tap "Send as text message", the message is passed to a page on mailtochatapp.com in the part of the address after "#", which your browser never sends to our server; the page only hands it to your phone's Messages app.

MailToChat for Outlook

The MailToChat add-in for Outlook works like the Gmail add-on: when you open it on an email, it reads that email's sender, subject and text inside Outlook to show the cleaned-up message. It runs in your mailbox from a page on mailtochatapp.com, does not send the email to any MailToChat server, does not store it, and cannot read other emails or send email on your behalf.

Google user data and Limited Use

MailToChat for Gmail requests only these Google permissions: running as a Gmail add-on (gmail.addons.execute) and viewing the email you have open while the add-on is running (gmail.addons.current.message.readonly). The add-on uses the sender, subject and text of that one email only to show you a cleaned-up message to send, inside the add-on, at your request.

MailToChat's use and transfer of information received from Google APIs to any other app will adhere to the Google API Services User Data Policy, including the Limited Use requirements. We do not sell Google user data, use it for advertising, or transfer it to anyone, and no person at MailToChat reads it.

No AI or machine learning training

MailToChat does not use Google Workspace data, including Gmail content, or any email content you share with the app, to develop, improve or train generalized or non-personalized AI or machine learning models. The Gmail add-on's clean-up is done with fixed rules and no AI model, and Gmail content is never sent to any AI service. The optional AI summary in the iPhone app is described above; neither we nor our AI provider use that text for training.

How your data is protected

• Data minimization: the add-on can read only the email that is open, only while it runs. It cannot read other emails, change your mailbox or send email.
• No storage: email content is processed in memory to build the message and is not stored, logged, cached or backed up by MailToChat, on any server or database. This includes text sent for an AI summary.
• Google's secure infrastructure: the Gmail add-on runs entirely within Google Apps Script, protected by Google's security and access controls. No MailToChat server receives your Gmail content.
• Encryption in transit: all connections, including to Google and to mailtochatapp.com, use HTTPS (TLS) encryption.
• Text passed through our website stays private: when you choose "Send as text message", the message is placed after "#" in the web address, a part browsers never send to any server, so it never reaches our website.
• On your iPhone: history is kept in the app's private storage, which iOS isolates from other apps and encrypts when your phone is locked with a passcode. It never leaves the phone.
• Access control: the MailToChat developer accounts (Apple, Google, Microsoft, Anthropic, RevenueCat and website hosting) are protected with two-step verification and are accessible only to the developer.
• Revoking access: you can remove the add-on's access at any time at myaccount.google.com/connections, and delete the iPhone app's history with Clear or by deleting the app.
• Security issues: report suspected vulnerabilities to support@mailtochatapp.com. If we learn of an incident affecting your information, we will notify affected users and the relevant authorities as required by law.

Information stored on your phone

To show your History screen, the app keeps a short record of messages you forwarded: the subject and sender name (when the email had them), the first part of the message, whether you used WhatsApp or text, and when. This record is stored only on your phone, is limited to your 50 most recent forwards, and can be deleted at any time with Clear on the History screen. Deleting the app also deletes it.

Clipboard

The app reads your clipboard only when you tap Paste, and copies to your clipboard only when you tap Copy.

Contacts

MailToChat does not access your contacts. You choose who receives a message inside WhatsApp or Messages.

WhatsApp and Messages

When you send a message, it is sent by WhatsApp or your phone's messaging app, not by MailToChat. Those services handle the message under their own privacy policies. Standard carrier rates may apply to text messages.

Information we collect

We do not collect personal information through the app, other than the anonymous app ID, AI usage count and purchase status described above. The app has no analytics, advertising or tracking tools. If you choose to share crash reports with developers in your iPhone's settings, Apple may provide us with anonymous crash data, which we use only to fix problems.

If you email us, we receive your email address and whatever you write, and use it only to reply to you.

Sharing and selling

We don't sell or rent personal information. We share data only with the service providers named above (Anthropic for AI summaries you request, RevenueCat and Apple for subscriptions), only to provide those features.

Children

MailToChat is not directed to children under 13, and we do not knowingly collect information from children.

Your choices and rights

Because your information stays on your device, you control it directly: edit messages before sending, clear History in the app, or delete the app. If you have a question or a request about your privacy, email support@mailtochatapp.com.

Changes to this policy

If we add features that change how information is handled, we will update this policy before releasing them, change the date above, and ask for your permission in the app where required.
