- free tier: Free tier: 5 GB per transfer (registered, free), 2 GB per transfer (Light, no registration). '1回の転送容量' is 無制限 only on the 330/550-yen business plan. The site's own headline says 無料無制限 — the plan table contradicts it. No total storage: '転送容量は1回に転送できる最大容量となり、何度でもご利用いただけます'. | unit: GB | metered on: stored-bytes | read on: 2026-10-21 | source: [1]

- limits:
  - retention-clamped: Retention 3 days [1]

- limits note: per-object-cap 5 GB (free) / 2 GB (guest). Retention 3 days guest, 7 days free registered, 30 days business. Free tier gets throttled transfer speed (`△` vs `〇`).
- interface detail: rest
- tooling: Web form; no API, no rclone backend.
- composes with: 5 GB x unlimited sends, but 7-day retention on free means chaining is strictly a re-send loop, not accumulation.
- reliability: Running since 2004, ~3M users/month, run by 株式会社ファルコ. Stable, but the 無料無制限 headline on the marketing page is marketing — the plan table is the truth.
- notes: the same as the free tier
