Every photo app asks for trust: trust that it won’t look at your photos, won’t train on them, won’t change the terms later.

Stream is built so that there is nothing to trust us with.

Photos are personal data. They are also personal memory.

Stream starts from a clear belief:

Users should not have to depend on one cloud platform just to get a good photo experience.

(Without Uploading Everything to the Cloud)

TL;DR: This guide shows how to merge and deduplicate photos across your phone and NAS (WebDAV), plus self-hosted libraries like Immich/PhotoPrism—without uploading everything to a cloud service. You’ll connect sources in place, review duplicates, and clean up safely on the original storage.

If you store photos both on your phone and on a NAS, you’ve probably run into this problem:

• The same photos exist on your phone, your NAS, and backups
• Files were copied multiple times over the years
• Storage keeps growing, but you’re not sure what’s safe to delete
• Most photo apps assume one cloud library, not multiple sources

What is Stream app?

Stream is a personal photo management tool designed for NAS users. It is just a management interface and does not store your photo data, so using Stream will not affect your original data. You can stop using Stream at any time without losing any data.
