Olympus Browser is free, with ad blocking built in. Premium turns the full engine on: the complete filter lists — more ad sources, more trackers, more annoyance rules — and the aggressive redirect defenses, kept current as sites change their tricks. On top of the free tier's standard lists, Premium adds the extended rule sets and priority updates. Same promise as the free tier — real, maintained blocking — with everything we've got switched on.
Every subscription starts with a 3-day free trial. Full Premium from the first minute — not a reduced demo. Cancel during the trial and you pay nothing.
One monthly price, shown at checkout before you confirm. Cancel in a couple of taps from your account page; Premium stays on until the end of the paid month, and the free browser keeps working either way.
Premium is sold here, not through an app store. After checkout you get a license key: paste it into the app (⋮ → Premium → Enter license key) and Premium unlocks on your phone. One key covers your own devices.
