Local Spam Filter & Block Anonymous Callers (100% Privacy)

Block annoying telemarketers, scammers, and anonymous callers without sharing your contacts with commercial parties. Because PaSS does nothing by itself, you have full control. Create smart incoming rules yourself and decide who is still allowed to call you.

Discover why the local PaSS spam filter is the safest choice:

100% Privacy (No cloud uploads)

With many other spam apps, you have to upload your entire address book to their servers, after which your data is shared. PaSS works fundamentally differently: the app runs completely offline on your device. Your contacts and call data never leave your phone. Total privacy guaranteed.

Stop anonymous and hidden callers

Do you often get calls from numbers without caller ID? Just easily create an incoming rule in PaSS. You choose the condition that the number is 'unknown / hidden', and the app will then automatically reject the call. This way, you will never be bothered by anonymous callers again.

Download spam lists or make your own

In PaSS, you can easily download ready-made spam lists and add them to your rules. You can also easily keep your own list of annoying numbers. Link such a list as a condition to an incoming rule, and you will instantly be rid of unwanted phone calls.

Exceptions and smart combinations

The spam filter isn't a simple on/off switch; you build the rules yourself. For example, block all incoming calls from a certain country, but instantly add a second condition as an exception. Is someone from that country in your contacts? Then your phone will ring as usual, so you always remain reachable to people you know.

Silence or reject immediately? You choose

What should happen when a spammer or anonymous caller calls? You decide that completely yourself per rule with a handy action. Let PaSS firmly reject the call, so the caller hears a busy signal. Or choose the 'Silence call' action, so your phone doesn't ring but you can quietly see the call later in your log.
