About Viallo
What Viallo Is
Viallo is a private photo sharing platform for travelers and families. People upload their photos into albums and share them through a private link. The link recipient opens a full-quality gallery in any browser, with a lightbox, an interactive map, and photos grouped by location. There is no account requirement on the viewing side, no app to install, and no compression applied to the original files.
Viallo runs as a web application, so the same experience works on a phone, a tablet, or a desktop. The platform is offered on a freemium model: a free tier covers casual use, and paid tiers add password-protected links, view analytics, user-to-user sharing, and larger storage.
Why We Built It
Most popular ways to send photos make trade-offs the sender rarely chooses. Group chats and social platforms strip resolution and metadata. Cloud galleries usually require the recipient to create an account or install an app to see anything meaningful. Larger platforms reserve the right to use uploaded images to train models or to power advertising.
Viallo was built around a different default. The viewer should not have to sign up to look at someone's holiday photos. The original file should reach them at full resolution. The owner should keep control of who can see what, and should be able to revoke that access at any time. None of the photos should ever be used for AI training, data mining, or advertising.
How It Works
A user creates an album and uploads photos. Viallo extracts EXIF metadata, including GPS coordinates, camera model, and the time each photo was taken. When GPS data is present, photos are grouped by geographic proximity using the DBSCAN clustering algorithm. Each cluster is reverse-geocoded to a readable place name, so an album organizes itself into recognizable stops on a trip without manual tagging. Photos without GPS data are attached to the nearest cluster by timestamp.
Sharing produces a unique link per album. The link can be password-protected, downloads can be enabled or disabled, and the link can be revoked at any time. On paid tiers, the album owner sees analytics for that link: total views, unique visitors, devices, browsers, and approximate location.
Privacy & Data
Viallo does not use uploaded photos for AI training, data mining, or advertising. The platform sends only transactional email — password resets, share notifications, new photo notifications — and does not run a marketing newsletter.
Users can export their data at any time as a machine-readable JSON file that includes account information, album metadata, photo metadata, places, and sharing information. Account deletion is immediate and irreversible: photos are removed from storage and account records are removed from the database in the same operation. The full data handling practices are documented in the Privacy Policy and GDPR page.
