Support

Particle is made by one person, and support is by email. Write tosupport@particle-reader.com and you get a reply within a few days.

For a bug, include the device and system version, the app version (Settings → About) and what you did before it went wrong. If crash reports are on, the report ID shown in Settings lets the crash be matched to your message.

Reading without an account

Particle reads EPUB and PDF files on your device without an account or a subscription, and stays that way. An account is only needed for Particle Sync.

Account

• Sign in or create an account under Menu → Account. "Forgot password?" on the sign-in form sends a reset link.
• Delete your account under Menu → Account → Delete account. This removes the account and everything synced with it — books, progress, highlights, bookshelves and files — and cannot be undone. It does not cancel a subscription; see below.

Particle Sync subscription

• Particle Sync is an optional auto-renewing subscription, billed by the app store you bought it from. Menu → Account → Subscription shows its status and opens the store's management page.
• To cancel, use the store's subscription settings — on an iPhone or iPad, Settings → Apple Account → Subscriptions. Sync stops at the end of the paid period; your books stay on your devices.
• Bought it before? Sign in with the same Particle account. If the subscription does not show, open Menu → Account → Subscription and tap Restore purchases.
• Refunds are handled by the store, not by Particle.
