Frequently asked questions

Start here. Follow the details.

Where should I start with online privacy?

Pick a service you use often. Check what data it asks for, the permissions you granted and what you can decline without losing a useful feature. That gives you one practical change to make and check, rather than an endless list of settings.

Is a long password enough to protect an account?

It also needs to be unpredictable and unique to that account. A famous quote can be long and easy to guess. Use a password manager’s generator for everyday accounts, then enable a second factor where the service supports it.

Does a VPN make me anonymous online?

No. A VPN protects the connection between your device and its server for the traffic it handles. It moves some trust to the provider. Signed-in accounts, cookies and your browser fingerprint can still identify you.

What does private browsing actually hide?

It limits what the browser keeps after the session, such as local history and session cookies. It does not hide your IP address from websites or make you invisible on the network. Downloaded files remain on your device.

Does encrypted email protect every message I send?

Protection depends on the recipient and the sending method. A message between accounts using compatible end-to-end encryption follows a different path from ordinary email sent to another provider. Check how you would recover old messages before changing addresses.

How can I keep cloud files confidential?

You can encrypt files before syncing them, using a vault whose key you keep. The provider then receives encrypted files. You still need to protect the device that opens the vault, keep recovery information and maintain an independent backup.

What should I avoid sharing with an AI service?

Do not share passwords, private keys or confidential documents without checking that the service and intended use are appropriate. For an everyday request, replace names, remove contact details and include only the relevant passage. A redacted copy is often enough.

Which phone settings help reduce data collection?

Start by removing apps you no longer use. Then review access to location, the microphone, contacts and photos. Access limited to when you use the app is often enough. Histories stored in online accounts have separate controls.

Is my router’s firewall enough for my computer?

It protects a network boundary. The computer’s own firewall still helps against other local devices and when you join a different Wi-Fi network. Review allowed applications, network profiles and exceptions left behind by old software.

Do Pi-hole and AdGuard Home remove every ad?

No. They can block domains on their lists when devices actually use their DNS service. Ads served from the same domain as the content may remain. A device using another DNS service can also bypass the filter.

Is hosting data at home always safer?

You gain control, but you take responsibility for updates, access, backups and failures. A poorly maintained server can expose more data than a managed service. Decide one use case at a time, based on the time and skills available.

How can I avoid losing my accounts with my phone?

Prepare recovery methods that do not all depend on that phone: recovery codes, a spare second factor or the service’s recovery process. Keep them somewhere safe and check that you can reach them without signing in to the account you are trying to recover.
