HoardDen is a small app for keeping a personal stash of the anime, shows, movies, manga, comics, games, and music you collect — and for sharing as much (or as little) of that as you choose with friends. This page explains, in plain language, what information the app keeps and what happens to it.
Your account. When you create an account we store your email address, the username you pick, and your password — kept only as a secure, scrambled hash by our sign-in provider; we never see or store the plain password. If you turn on the optional authenticator app security, we store what's needed to verify your sign-in codes. If you link a Google account for faster sign-in, Google tells us that account's name, email, and picture; we never receive your Google password.
Your profile. Your profile picture, bio, appearance choices (wallpaper, banner, a profile video link), a showcase of favorites, and your status setting (online / stepped away / do not disturb / appear offline) are stored so your profile works the way you set it up. While the app is open, it also keeps your "last seen" time up to date.
Your stash. The titles you add — with your statuses, ratings, notes, collection details (format, condition, what you paid and what it's worth), and where-to-watch links — are stored so your list works. You can export your list as a file at any time from inside the app.
Things you post and send. Feed posts, comments, likes, favorites, and follows are stored so the Feed works. Photos you add to your gallery, attach to posts, or send are stored as image files. Direct messages you send to friends are stored so the conversation is there when you come back.
Your profile has a visibility setting you choose. New profiles start hidden. You can set yours to Hidden (nobody sees your profile or list), Friends only, Friends and their friends, or Everyone. Anyone who can't view your profile sees only your name, profile picture, and badges, with a note that the profile is private. Separately, your personal share link shows your list to anyone who has it — treat it like a key.
The Feed is for members. Posts, comments, and likes in the Feed are visible to other signed-in HoardDen members, along with your username and profile picture. Photos you upload are stored as public image files: anyone who has a photo's web address can view that photo, even if they aren't signed in — so only upload pictures you're comfortable being public.
Friends and activity. People who aren't your friends see only your username and picture where you've posted in the Feed. If you set your status to "appear offline," that's how you're shown even while you're using the app.
Direct messages are between two people. Only you and the friend you're messaging can read your conversation — it's enforced by the database, not just hidden in the app. Messages are stored on our servers (they are not end-to-end encrypted), so please don't send anything in a message that you need to keep secret from a server. If you make a voice or video call inside a conversation, the sound and picture travel directly between the two devices and are never recorded or stored. A short note that the call happened is kept in the conversation, the same as a message.
Some features check outside services when you use them, and those services receive the thing being looked up: scanning a barcode sends the code to barcode/product databases; searching for a title sends the title to the catalog for that kind of media (for example TMDB for movies, TVmaze for shows, and public game catalogs for games); identifying something from a photo sends that photo to Google's Gemini AI for recognition; linking a title for release alerts sends its name to AniList, AnimeSchedule, or MangaDex; and an automatic hourly check asks those same services whether new episodes or chapters of your tracked titles have appeared, so it can put an alert in your bell. Release alerts are off unless you switch them on.
We do not sell your information. We do not show ads. We do not track you across other websites or apps, and we don't use advertising or analytics trackers.
HoardDen runs on Supabase (accounts and database) and our own server (website hosting and the small server helpers behind photo identification, search, and release alerts). Depending on the features you use, title information also passes through Google (sign-in and photo identification), AniList, AnimeSchedule, MangaDex, TMDB, TVmaze, and public catalogs such as Wikipedia, CheapShark, SteamSpy, and MusicBrainz — each under its own privacy policy.
You can change your picture, bio, status, sharing, and notification settings at any time inside the app. You can delete your account yourself in Profile → Danger zone: type your username to confirm, and your list, posts, photos, comments, messages, and account are removed. Deleting can't be undone. Data is kept on reputable hosted services, but no system is perfect — the export button is there if you want your own copy of your list.
