## Frequently asked questions

### Are these guides written for beginners?

Yes. Every guide assumes no technical background and explains each step in plain language, with separate instructions for Windows, Mac, iPhone, and Android where it matters.

### Are the guides up to date?

They were written and reviewed in 2026 against current versions of Windows, macOS, iOS, and Android. Interfaces change over time, so menu names may shift slightly.

### Do I need to install anything?

No. All eight guides cover tasks you can do with the software already on your device, plus free built-in options. Where a free app helps, such as a password manager, the guide names one.

### Can I share these guides with family?

Yes. They are free to read and share, and they are written to be forwarded to parents, grandparents, or anyone who asks you for tech help.
