How to use SinSpam

Install the app, activate protection and choose the peace of mind you need. SinSpam is one Android app with four levels: Low, Medium, High and Extreme.

How do I install and activate SinSpam?

1. Install SinSpam from Google Play and open the app.
2. Set SinSpam as your call screening app. Return to the app and tap Continue.
3. Allow access to Contacts and tap Continue.
4. Enable display over other apps, return to SinSpam and tap Continue.
5. Allow notifications and tap Continue to finish activation.
6. New installations start in Extreme Mode. Once setup is complete, that level is already active.

The app guides you through one access at a time. Keep all four active to use SinSpam. If any access is missing, open the app: it shows the step needed to restore it before filtering resumes.

How do I use Extreme Mode?

Tap Enable Extreme Mode on Home or choose Extreme in Blocking. It activates as soon as you tap it. You do not need another app or a payment.

In Extreme Mode, your contacts can call you and numbers outside your contacts are rejected. Save the numbers you want to hear from in Contacts. You can choose another level in Blocking.

Which protection level can I choose?

• Low: For business phones.
• Medium: For work and personal life.
• High: For your personal phone.
• Extreme: Your circle, your peace of mind.

Change the level in Blocking. Low, Medium and High use community information downloaded to your phone.

Is SinSpam free? Does it have ads?

SinSpam is 100% free. There are no subscriptions, in-app purchases or paid features. Extreme Mode is free and has no ads.

In Low, Medium and High, the caller windows SinSpam displays include a mercax.combanner. The banner does not appear on Home or while using Extreme Mode. The app keeps a link acknowledging its sponsor.

Revenue from the mercax.com store covers the infrastructure and project expenses so SinSpam can be offered for free.

Where can I see my calls and vote?

Open Calls. It groups your latest 1500 observed calls by number, including blocked calls. Open a number to see individual calls, vote Annoying or Not annoying, or change your vote.

How do I return a call?

Tap a visible phone number to open the dialer, then start the call there.

How do I allow or reject a number?

Open My rules, enter the number and tap Allow or Reject. You can review and remove saved rules on the same screen. These actions are also available in a number’s details.

Can I turn off the block sound?

Yes. Open Blocking → Controls and change Sound when blocking. The app remembers your choice.

What is the Extreme Mode daily summary?

With Extreme Mode active, a notification scheduled for 10 p.m. shows today’s blocked calls. Keep SinSpam notifications allowed to receive it.

Does it work without a connection?

Yes. SinSpam uses the information already on your phone to filter calls. Connect to receive community updates and send pending contributions.

Which Android versions and languages are supported?

SinSpam works on Android 10 or later. The interface supports English, Spanish, Portuguese and Hindi. It uses the first supported language in your phone’s preferences, including regional variants; if none match, it uses English. The country used to interpret national phone numbers does not change the language.

What data does SinSpam process?

Using the filter shares observed callers’ numbers, call dates and votes, linked to a random installation identifier. Contacts are checked on your phone; names and your address book are not sent. The app privacy notice explains the data, its purposes and retention periods.

What does Google check with Play Integrity?

Google checks the app and device to help detect tampering or emulation. This check does not verify the person or the accuracy of each vote.

How do I delete my server contributions?

Open Help → My server contributions → Delete my server contributions and confirm. This deletes this installation’s calls and votes from the server and clears its old pending uploads. Your phone’s history, rules and personal votes remain. Continued use creates new contributions. Community figures already distributed do not change immediately.
