What does the MailMergic Offline app send over the internet?
by Meelika Kivi · Customer Support
In normal use, the only automatic network calls go to MailMergic and Google infrastructure, and none of them carry document or recipient data:
- License validation sends your license key together with a device fingerprint, hostname, and operating system.
- An anti-tamper time check sends the platform and app version only.
- Update checks retrieve release metadata only.
The one feature that intentionally transmits recipient details and rendered content is email sending, and only if you configure a sender and choose to send. That traffic is routed through your own SMTP server, not through MailMergic.
