Summary

Multi-DNS Adblock does not collect, store, or sell your personal data. The app requires no account, uses no advertising or analytics SDKs, and does not send your browsing history to us. The only data that leaves your device is the DNS queries you request, which are forwarded to the DNS providers of your choice — as explained below.

1. Data we collect

None. We do not collect your name, email address, phone number, location, or device identifiers. There is no account, no registration, and no behavioral tracking.

The following data stays on your own device and is never sent to us:

DNS query logs in memory (RAM) while the app is running, to display the Sniffer and statistics. These logs disappear when the app is closed.
Optional disk log — off by default. If you enable it, logs are stored encrypted on the device and automatically deleted after 7 days.
App settings — your chosen DNS providers, per-app profiles, and preferences.
Optional log export — only if you export it yourself; the file is encrypted (AES-256-GCM via AndroidKeyStore).

2. Where your DNS queries go

When an app on your device requests the address of a domain, Multi-DNS Adblock forwards that query to the DNS providers you selected in settings (up to 3 voters, according to the quorum mode). Those providers receive the requested domain name and your IP address, because that is how DNS works.

DNS providers available in the app:

Provider	Role
AdGuard DNS Default	Ad-blocking voter
Control D Ads and Tracking (p2)	Ad-blocking voter
LibreDNS NoAds	Ad-blocking voter
CleanBrowsing Security Filter	Security voter
DNSForge	Ad-blocking voter
Quad9	Security only (malware/phishing), not an ad voter
AhaDNS (India)	Backup (activated after live verification)
Alternate DNS	Backup (activated after live verification)
RethinkDNS Sky (Modular)	Backup
Custom AdGuard Private / Custom NextDNS	Your own custom slots

We cannot control or guarantee the logging practices of those DNS providers. Each provider has its own privacy policy that applies to the data it receives. You are free to change or disable any provider in the app settings.

While the 60-second Reward Claim Mode is active (at your initiative), queries are forwarded to your network DNS instead of the providers above.

3. App and data updates

The app checks for updates (manifest, DNS provider list, and blocklist) at mrr.ai.id. This check sends no personal data — only a version request. Update files are verified with a digital signature (ECDSA P-256) before use. APK updates are downloaded from the same website.

4. Donations

Donations are voluntary and made via QRIS. Payment is processed entirely by the bank or e-wallet app you use to scan the QR code. We do not receive, process, or store any payment data.

5. Crash reports

Crash reports are opt-in (off by default). If you enable them, reports are sent without domain names and without IP addresses.

6. Children

This service is not directed specifically at children. Because we do not collect any personal data, no children's data is processed by us.

7. Security

Data on the device is protected by device encryption (File-Based Encryption).
Log exports are encrypted (AES-256-GCM via AndroidKeyStore).
All update files are verified with a digital signature before use; files that fail verification are rejected.
No server of ours stores your data, so there is no user database on our side that could leak.

8. Legal basis and your rights (Law No. 27 of 2022 on Personal Data Protection, "UU PDP")

The legal basis for processing DNS queries is your consent, given during onboarding (before the VPN permission is requested) and withdrawable at any time by turning off protection or uninstalling the app.

Because we do not store your personal data on any server, most rights can be exercised directly on your device:

Right to erasure: delete logs in the app, or uninstall the app — all data stored on the device is deleted with it.
Right to withdraw consent: turn off protection or uninstall the app.
Right of access and rectification: there is no data of yours on our servers; data on the device can be viewed on the Sniffer and Settings screens.
Complaints: you may raise objections or complaints with us at me@mrr.ai.id, and with the personal data protection authority under the UU PDP.

9. Retention and deletion

We do not store your personal data on any server. Logs on the device are automatically deleted after 7 days (if disk logging is enabled). Uninstalling the app deletes all data stored on the device.

10. Changes to this policy

Changes to this policy will be announced through app updates or the mrr.ai.id website. Continued use of the app after a change means you accept the new policy.
