Zirah: Stop Scams & Collectors

Zirah is a protective layer against scams and collection harassment: calls from online-loan collectors, scam texts and chats, phishing links, dangerous APK files, transfer scams, and intimidation. Every check runs on your phone. No account, no server, no ads. Message content never leaves the device. SCAM AND COLLECTOR CALLS • Reject calls from blocked numbers and number prefixes before the phone rings. • Reject, silence, or label every number outside your contacts. Schedule it, for example nights only. • Burst detection: when several similar numbers call within a short time, Zirah suggests a one-tap prefix block. • Emergency and short service numbers are never rejected. A repeat-caller exception lets couriers or doctors through. SCAM TEXTS AND CHATS • SMS and WhatsApp notifications are scored with weighted keywords and a small on-device model. Scam, threat, and loan-promotion messages are hidden with a written reason. The original message stays in its app. • Saved contacts, senders you allow, OTP codes, and bank SMS are never hidden. • "Not spam" and "This is spam" re-weight the categories on your phone. PHISHING LINKS AND DANGEROUS APKS • Links that imitate banks, e-wallets, couriers, or government sites are recognised without opening them: lookalike domains, punycode, IP addresses, and fake login paths. • APK files or .apk links sent in chats trigger a warning. • Apps installed from outside official stores that ask for Contacts or SMS are flagged, with an Uninstall button. PAYMENT SCAMS • "Wrong transfer" messages, transfer requests, account numbers, or QRIS codes from unknown numbers trigger a "Don't transfer yet" warning, with a link to cekrekening.id. LENDER CHECK (INDONESIA) • Match an app or company name against the list of OJK-licensed lenders bundled in the app. The data date is always shown. • A loan tracker for legitimate loans with due-date reminders. QUIET MODE • One tap, also from Quick Settings: hold calls and notifications from numbers outside your contacts for 1, 8, or 24 hours. • A message template asking family and friends to ignore collectors who mention your name. EVIDENCE AND YOUR RIGHTS • A chronology of rejected calls and held messages becomes a PDF on your phone, hash-chained so changes are visible. A complaint letter for OJK, Satgas PASTI, the police, or Komdigi is pre-filled. • A consumer-rights guide: what collectors may not do and where to report. SETTINGS • Low, Balanced, or Strict sensitivity. Your own weighted keywords. • Per-group actions: hide, label only, or leave. • App lock with fingerprint, face, or phone PIN. Disguise icon. Dark theme. Indonesian or English. • Password-encrypted backup. Delete all data with one confirmation. • 7- and 30-day trend charts, weekly report, home screen widget. PRIVACY • No account, no ads, no server. The app does not use the internet. • Contacts are read only to recognise callers and senders, never copied. • Notification access is used only to recognise and hide scam and collector messages, as you choose. Zirah does not erase legitimate loan obligations and cannot guarantee that every scam is detected. It helps you stop harassment, recognise dangerous messages, and keep evidence. Zirah is not an official OJK or government app.
