Postboi PRE-RELEASE
Form PB-01 Privacy policy Revised 25 September 2026 Postboi · United Kingdom

What we keep, and what we don't.

Postboi ("we") is a messaging service operated from the United Kingdom. This policy explains what we collect when you use postboi.app, the dashboard, the sending API and hosted form endpoints, and what we do with it.

The manifest

What we collect

  • Account details. Your name and email address, used to sign you in (we send magic links; there are no passwords) and to contact you about your account.
  • Product news. Now and then we email customers about what's new in Postboi. You can say no when you sign up, and every one of these emails has an unsubscribe link; you can also switch them off or on under Account. We keep your answer, and when and where you gave it. These are separate from sign-in links, invites and the notifications you choose, which you get either way.
  • Session data. IP address and browser user agent for active sign-in sessions, used for security.
  • Send log. For every email sent through the service we log the sender address, recipient addresses, subject line, delivery status (sent, bounced, complained) and the message body. The body is stored to power the message preview in your dashboard; it stays inside your account's log, is never used for anything else, and is deleted with your account.
  • Form submissions. Messages posted to your hosted form endpoints are processed the same way as sent email: rendered, delivered to the team member you chose, and stored in your send log. Submissions are spam-checked (and rate-limited) before anything is stored or sent.
  • API keys. Stored as one-way hashes; we cannot read them back.
  • Usage and billing. Monthly send counts, your plan, and Stripe customer and subscription identifiers. Card details go directly to Stripe and never touch our servers.
  • Custom domains. Domain names and DNS verification records you add for sending.

On your behalf

Your recipients' data

When you send email through Postboi, you are responsible for having a lawful basis to contact your recipients. We process their email addresses and your subject lines on your behalf, solely to deliver mail and to track delivery status and abuse (bounces and complaints).

Subprocessors

Not for sale

Who we share it with

We use a small number of processors, only for what the service needs to function:

Processors · the whole list

Amazon Web Services (SES)
email delivery
Stripe
payments and subscription billing
Cloudflare
hosting and data storage
Google Analytics
website analytics Only if you accept cookies

Until you accept cookies, analytics runs in cookieless consent mode and sets nothing. We do not sell your data or share it with anyone else.

The jar

Cookies

We use a session cookie to keep you signed in (strictly necessary), a cookie on the sign-in page that remembers your answer about product news until your account is created, and, only with your consent, Google Analytics cookies to understand how the site is used. You can decline these in the cookie banner and the site works identically.

How long we hold it

Retention

We keep your data while your account is active. Send metadata is retained to power your message log and to prevent abuse. If you delete your account, we remove your personal data, keeping only what we must for legal, billing or anti-abuse reasons.

Return to sender

Your rights

Under UK GDPR you can ask for a copy of your data, ask us to correct or delete it, or object to how we use it. Email support@postboi.app and we'll sort it out. You can also complain to the ICO (ico.org.uk).

Revisions

Changes

If this policy changes materially we'll note it here and update the date above. Questions? support@postboi.app.
