description: How Sellu automates aggressively without looking like a bot.

<FeatureVideo src="/videos/account-safety.mp4" title="Account safety demo" />

Automation is only worth it if your account survives it. Everything Sellu does runs
inside **your own browser session** — no shared bots, no server-side logins — and every
action goes through a safety layer designed to look like a fast human, not a script.

## Human-like pacing

- Every write action (message, offer, repost, follow…) is queued with a per-action
  minimum delay plus **random jitter** — typically several seconds between actions.
- **Quantity-scaled slowdowns**: the bigger the batch, the longer the gaps (large jobs
  run up to 2.5× slower per action). A 200-item job spreads naturally over hours.
- **Daily caps** are enforced per action type — for example 80 messages, 60 offers,
  100 follows, and 100 reposts per day.

## Graceful failure handling

- **Rate limits & captchas** — on a 429 or an unsolved challenge, the entire queue pauses
  (about a minute) and you get a visible banner and toast, instead of the extension
  hammering the marketplace. DataDome and Cloudflare challenges are solved silently in
  the background when possible.
- **Blocked requests** — if the marketplace blocks a request from the extension, it's
  transparently re-issued through the real page context.
- **Expired sessions** — a 401 triggers an automatic session refresh and one retry;
  logging out is detected and handled cleanly.

## Where your data lives

Listings, orders, conversations, notes, and SKUs are cached in your browser's local
storage and IndexedDB. Your stock, publications, and sales sync to **your own Sellu
dashboard** so you can manage them from anywhere — but your **Vinted credentials never
leave your browser**, and no marketplace action is ever performed from our servers. AI
generation runs on Sellu's servers using the credits in your plan; only the photos and
listing fields you're generating from are sent.

<Callout type="warn" title="No safety layer makes automation risk-free">
  These protections dramatically reduce risk, but any automation is used at your own
  discretion. Start with conservative intervals and small batches, especially on a
  seasoned account you care about.
