Semak Dulu Privacy Policy

Last updated: 7 October 2026

Developer: Ticherhaz
Privacy contact: ticherhaz@gmail.com

1. Scope

This Privacy Policy explains how Semak Dulu handles information when you use the Android app. It applies to the app and its optional cloud analysis, advertising, consent, sharing, and Google Play billing features.

2. Information you provide

You may enter or explicitly share messages, links, phone numbers, email addresses, payment identifiers, QR codes, APK metadata, and images. Images are processed on-device to extract text or QR content. Do not submit passwords, PINs, OTPs, TACs, recovery phrases, card security codes (CVV/CVC), or other secrets.

3. Local processing and storage

Local checks are performed on your device. Payment card formats (Luhn check) and QR code payloads (including EMVCo DuitNow QR payee extraction) are analyzed strictly on-device without transmission. If you keep check history, the app stores the input, check type, risk signals, result, timestamp, optional cloud response, and a reference to a selected image in app-local storage. Full payment card numbers and secrets are redacted and never stored or sent off-device. App settings store your legal acceptance, age confirmation, language, country/region preference, theme, history-retention choice, cloud-check quota, and subscription-status cache.

The app does not require an account, profile, password, or direct user registration.

4. Optional cloud analysis

Cloud analysis is optional and is disabled while Local-Only Analysis is on. When you choose cloud analysis, the app sends the text being checked, after applying available redaction rules (stripping passwords, OTPs, CVVs, and payment card numbers) and a length limit, to Google Firebase AI / Gemini to generate an assessment. Redaction is not guaranteed to remove every sensitive detail. Do not use cloud analysis for sensitive financial or personal information.

Images and APK files are not uploaded by the app for cloud analysis. However, text extracted on-device from an image or QR code may be sent if you choose cloud analysis for that content.

5. Google services, advertising, and purchases

The Google distribution of Semak Dulu uses Google User Messaging Platform for advertising consent, Google Mobile Ads for banner, interstitial, and rewarded ads, Google Play Billing for Premium purchases, Firebase Realtime Database for public safety configuration, and Firebase AI / Gemini for optional cloud analysis.

These providers may process technical, device, network, advertising, purchase, and service-operation information under their own terms and privacy policies. Your submitted check content and check results are not used by Semak Dulu to build advertising audiences. Subscription purchases and restoration are handled by Google Play; Semak Dulu does not receive or store your full payment-card details.

6. Sharing and disclosure

We do not sell your personal information. We share information only when needed to provide a feature you choose, such as cloud analysis, advertising, consent, billing, or Android sharing; when required by law; or to protect rights, safety, and security. If you use the sharing feature, you choose the recipient and are responsible for the information you share.

7. Retention, deletion, and backups

Check history stays on your device until you delete it, clear history, or select the 7-, 30-, or 90-day auto-delete setting. Files copied into the app for image processing are deleted when related history is removed where possible.

Uninstalling normally removes app-local data. If Android backup or device transfer is enabled, some app data may be included in an operating-system-managed backup or transfer and may remain there according to your backup provider's retention practices. Uninstalling does not remove data you exported or shared, information retained by Google services, or data in backups outside the app's control.

8. Security

The app uses HTTPS for network connections and limits processing to what is needed for the feature you select. No method of storage or transmission is completely secure. Avoid entering secrets, delete sensitive history promptly, and use Local-Only Analysis when appropriate.

9. Children

Semak Dulu is intended for people aged 18 and over. Do not use the app if you are under 18. If you believe a child has provided personal information through the app, contact Ticherhaz at ticherhaz@gmail.com.

10. Your choices and privacy requests

You can use Local-Only Analysis, decline or manage advertising consent where available, clear history, choose an auto-delete period, and avoid cloud analysis. To ask a privacy question or make a request, contact Ticherhaz at ticherhaz@gmail.com. We may need information to verify and process a request.

11. Changes to this policy

We may update this policy to reflect changes to the app, services, or law. The current version and its last-updated date will be available in the app and on this published page. Continued use after an update means you accept the updated policy to the extent permitted by law.
