Question 1

Will ad-blocking break apps I actually use?

Accepted Answer

Sometimes — and we test every blocked domain with you before finalising. The most common breakage is "free" apps that refuse to load if their ad SDK does not phone home (we whitelist those if you want to keep using them) and some shopping/banking apps that use the same analytics SDK as the trackers (we whitelist by domain). The whitelist becomes part of your written setup so you do not have to redo the testing later.

Question 2

Do I need to root my phone for this to work?

Accepted Answer

No. The non-root tiers (Light and Standard) get you about 70-85% of the benefit using only Private DNS, app-level blockers like Blokada, and tightened permissions. Root unlocks the Advanced and Maximum tiers because the system hosts file and Magisk modules can intercept traffic before it leaves the phone — but root is not required to make a meaningful privacy improvement. We will recommend the lowest tier that meets your goal.

Question 3

How is this different from just installing a VPN?

Accepted Answer

A VPN hides your IP from websites and your traffic from your ISP, which is one specific privacy concern. Privacy hardening tackles the much larger surface: the dozens of trackers and ad SDKs inside apps you use every day, the manufacturer telemetry that runs constantly in the background, the apps with location and microphone permission you forgot you granted, the manufacturer cloud sync you never opted into. A VPN does nothing about any of that. We can pair the hardening with a VPN if you want both layers.

Question 4

Will my battery life improve after this?

Accepted Answer

Usually a noticeable improvement — typically 5-15% better screen-on battery — because trackers and analytics SDKs make a surprising number of background network calls. The Maximum tier on a debloated GrapheneOS install commonly extends standby battery by 30%+ vs stock OEM Android. Performance also improves on lower-end devices because there is just less running in the background.

Question 5

Is this legal? Could it void my warranty?

Accepted Answer

The non-root tiers (Light, Standard) are entirely standard user-level configuration — no warranty implications, no legal grey area. The Advanced and Maximum tiers require root or a custom ROM, which voids the manufacturer warranty in the same way our standard rooting service does. We always disclose this before any work that affects warranty, and we keep your original boot image so you can revert if needed for a warranty repair.
