Activity status (green dot)

A small green dot on a friend’s avatar means they’ve been active in Manga Vault recently. It’s a low-fidelity online indicator — not a “they’re using the app right now” signal, but a “they’ve been active in the last 24 hours” signal.

How activity is tracked

Manga Vault sends a lightweight “I’m here” heartbeat to our servers when:

You open the app.
You return the app to foreground after being in background for more than ~5 minutes.

Each heartbeat updates a lastActiveAt timestamp on your profile. The green dot appears for friends whose timestamp is within the last 24 hours.

Where the dot appears

On a friend’s avatar in your Friends list
On a friend’s avatar on their profile page
On a friend’s avatar in the Lending modal friend picker (when you’re choosing who to lend to)

Privacy

You control whether friends can see your activity status:

Open Edit Profile.
Find Show Activity Status in privacy toggles.
Toggle off to hide your activity from friends.

When off:

Friends viewing your profile won’t see the green dot.
Your lastActiveAt is still updated on the server, but it’s filtered out of friend-facing API responses.

What the dot is not

Not a “currently online” indicator. We don’t track real-time presence.
Not a “they’ve read your message” indicator. Manga Vault doesn’t have direct messaging.
Not based on specific actions (it doesn’t matter what you did — opening the app counts).

I see all my friends as inactive

Most likely they haven’t opened the app in 24+ hours. This is normal. Manga Vault is the kind of app many users open less frequently than their messaging apps — that’s fine, not concerning.

Why 24 hours?

Shorter windows would surface as “barely anyone is online” since most users aren’t in the app every hour. 24 hours captures “active users this week” reliably without giving away minute-by-minute presence — a balance between useful and respectful of privacy.

Coordinating with friends

If you want to lend a manga or chat about a series and want to know when a friend is around, the activity dot is a rough heuristic. For real coordination, message them outside the app.
