Terms of service

DiffBell is provided as is. We work hard to check pages on schedule and deliver every alert, but we can't guarantee that no change will be missed or delayed. Don't use DiffBell for anything where a missed alert could cause serious harm.

Only watch pages you're allowed to access. Don't use DiffBell to overload websites or break their terms. We may suspend monitors that cause problems.

Pro subscriptions renew automatically, and you can cancel any time. If you're unhappy within 14 days of paying, email us for a full refund.
