Privacy Policy
Effective July 5, 2026
What we store
Your mail. Messages you receive and send are stored on our mail server so that you can read them — that is the product. They stay until you delete them or close your account.
Account data. Your MailHow address, a hash of your password (we never store the password itself), the domains you connect, your storage usage, and standard technical logs (connection times, IP addresses, delivery logs) kept for abuse prevention and debugging, retained for at most 30 days.
Cookies. One session cookie that keeps you signed in. No analytics trackers, no advertising cookies, no third-party scripts on any page.
What we never do
We do not read your mail except when strictly required to operate the service (e.g. automated spam filtering, or investigating a delivery failure you report). We do not sell, rent, or share your data with advertisers or data brokers. We do not train AI models on your mail.
Where your data lives
Mail is stored on our servers at Hetzner (Germany, EU). The web application runs on Vercel, and account metadata (not message content) is stored in a Neon PostgreSQL database. DNS for mailhow.com is served by Cloudflare. Each of these providers processes data on our behalf under their own data-processing agreements.
Email is email
Honest caveat: email as a protocol travels between servers, and while MailHow uses TLS for every connection it can, delivery to and from other providers is only as private as those providers make it. Mail stored on our server is protected by access controls and per-account isolation; it is not end-to-end encrypted.
Your rights
You can access all your mail at any time over IMAP or the web app (that is your export, in standard formats). Email hello@mailhow.com to request a copy of your account data, correct it, or delete your account — deletion removes your mailbox, messages, and account records within 30 days, except minimal records we must keep for legal reasons. If you are in the EU/EEA, these are your GDPR rights to access, rectification, erasure, and portability; you also have the right to complain to your local supervisory authority.
Contact
Privacy questions: hello@mailhow.com. We will update this policy as the service evolves and announce material changes by email before they take effect.
