AdSlayer Privacy Policy
AdSlayer has no account, no analytics, and no servers of its own. Everything it does — the rules it matches, the statistics it counts, the activity it logs — happens on your device and stays on your device. There is nothing to sync, nothing to back up to a cloud, and nothing for anyone else, including the developer, to see.
What the VPN permission is for
AdSlayer asks for VPN permission because that is the only sanctioned way for an Android app to inspect DNS requests device-wide without root access. It uses this permission for exactly one purpose: reading the domain name in each DNS query so it can be checked against your block rules, and forwarding allowed queries to your network's own resolver unchanged.
AdSlayer does not decrypt HTTPS traffic, does not install any certificate, and cannot read the content of your web browsing, messages, or any other app's traffic. Only the DNS query itself — a domain name — is ever inspected. Every other network request bypasses the tunnel entirely and takes its normal path.
What is stored, and where
All of the following live in a local database on your device and are never transmitted anywhere:
- Custom block rules and whitelist entries you add
- Category toggles and app-level protect/bypass choices
- Aggregated statistics — counts of blocked and allowed requests
- The activity log — domain, category, and verdict for recent filtering decisions
The activity log is deliberately temporary: detailed events are deleted after a retention window you control in Settings (7 days by default). Allowed requests are counted but not logged individually unless you turn that on yourself — allowed traffic vastly outnumbers blocked traffic, and logging all of it would mean storing a near-complete record of every domain your device visits, which this app does not do by default.
What leaves your device
Two things, and nothing else:
- Your normal DNS queries, forwarded to whichever resolver your network already uses — the same resolver your device would use without this app installed.
- Periodic block list downloads from their public publishers (AdAway, AdGuard, EasyList and Phishing Army). These are plain HTTP requests for a text file. They carry no account identifier, no advertising ID, and no device information beyond what any HTTP request inherently exposes to a server, such as your IP address.
AdSlayer contains no analytics software development kit, no crash-reporting service, and no third-party tracking library of any kind. Nothing about your use of the app is reported to the developer, because there is no channel built for that to happen through.
Third-party block lists
The domains AdSlayer blocks come from public lists maintained by AdAway, AdGuard, EasyList (distributed via The Firebog) and Phishing Army. AdSlayer downloads these lists directly from each publisher and is not affiliated with, and does not share data with, any of them.
Children's privacy
AdSlayer is not directed at children and does not knowingly collect personal information from anyone, of any age — it does not collect personal information from anyone at all, as described above.
Changes to this policy
If AdSlayer's data practices ever change, this page will be updated to describe them accurately before that change ships.
