Privacy policy · Effective November 10, 2026
What we collect, and what we leave alone.
Alien Tech Services LLC runs EndPaper Mail. This policy covers the hosted mail service, the webmail at mail.endpapermail.com, and the EndPaper Mail apps for Windows and Android.
What the service keeps
Your account
Your email address, the display name you enter, your plan, your storage limit and the date you signed up.
Your mail
Messages, folders, contacts and settings you store in your mailbox. We keep them to deliver and show your mail. Mail sealed for your address opens only with keys on your devices.
Your password
Sign-in uses the OPAQUE protocol, so your password never reaches our servers. We keep what OPAQUE needs to check it, plus your passkeys and authenticator settings.
Payments
Stripe takes paid-plan payments. We keep the Stripe customer and subscription IDs. Your card number goes to Stripe and never to us.
Abuse limits
The sign-up page records the IP address of each attempt to stop automated sign-ups. We delete these records after 2 days.
Server logs
Our mail servers log deliveries and sign-ins to stop spam, viruses and break-ins, and to fix problems.
The apps
The Windows and Android apps send no analytics, advertising or tracking data. They contain no ad or tracking code.
On your device
The Windows app keeps your saved sign-in in the Windows Credential Locker and its settings in your user folder. The Android app seals saved secrets with AES-256-GCM in the phone's hardware keystore.
Other mail providers
When you add Gmail, Yahoo, iCloud or another IMAP mailbox, the app connects straight to that provider. That mail and that password never pass through EndPaper servers. The provider's own privacy policy covers that mailbox.
Remote images and links
Remote images stay blocked until you allow them for a message. The app warns you before it opens a link that looks unsafe.
What we never do
We do not sell your data, show ads, or read your mail to profile you. We share data only with Stripe for payments, or when the law requires it.
Your choices
You can export your mail, delete messages, or ask us to close your account and delete your mailbox. Write to support@endpapermail.com from your EndPaper address. Cancel a paid plan anytime from the Manage billing link at the bottom of every page.
