Nebulosa

A private document & notification service

Nebulosa is a small, self-hosted application that delivers documents and notifications, on request, to a fixed set of personal accounts. It is not a public service and has no sign-up.

What this is

Nebulosa is operated privately for the owner and a few immediate family members. Through the application, an authorized person requests a document they own and the application delivers it to their own email-enabled devices. It also sends occasional system notifications about that activity.

There is no public registration, no newsletter, and no marketing of any kind. The set of recipients is small, known, and managed by hand.

Email practices

All email Nebulosa sends is transactional. Specifically:

  • Transactional only — every message is triggered by an explicit action in the application or is a system notification. No bulk or promotional mail is sent.
  • Opt-in recipients — messages go only to the owner's and family members' own accounts, all of whom have asked to receive them. Addresses are never purchased, rented, or scraped.
  • Bounces and complaints — delivery events are monitored; any address that hard-bounces or reports a complaint is removed immediately and not contacted again.
  • Removal — any recipient may ask to be removed at any time and is removed promptly.

Nebulosa's outbound mail is authenticated with SPF, DKIM, and DMARC, and is sent through a reputable email service provider in compliance with that provider's acceptable-use policy.

Privacy policy

Nebulosa is a private service and collects as little information as possible.

  • What is handled — the email addresses of the owner and the small number of family recipients, and the documents they request through the application.
  • How it is used — solely to deliver requested documents and related system notifications to those recipients.
  • Sharing — information is never sold, rented, or shared with third parties, except the email service provider used to transmit messages.
  • Tracking — this website sets no cookies, runs no analytics, and loads no third-party scripts. Emails contain no open- or click-tracking.
  • Retention — recipient details are kept only while a person remains an active recipient, and are deleted on request.
