Privacy

Seems like a mixed guide generally. It's fine, just some complaints:

8-12 random characters that are easy to remember and type in when you unlock your device.

Ironic that this comes from the EFF. Passphrases are much better for this type of stuff, and diceware is practically the gold standard to generate https://en.wikipedia.org/wiki/Diceware

Install Signal

More of a small complaint, but SimpleX is probably better if you're aiming for as much security/privacy as possible.

However if you will, use https://molly.im/ and torbot for android.

Back up your data regularly and store that backup in a safe place to save yourself from a headache later on. If you're storing your iPhone's backups online, we strongly suggest enabling the optional Advanced Data Protection feature, which turns on end-to-end encryption for most of the data stored in iCloud

I don't know too much about iCloud but i wouldn't trust apple with anything.

Here's some good alternatives: https://www.privacyguides.org/en/cloud

Dress for Anonymity and Safety

No criticism, just FYI this is called https://en.wikipedia.org/wiki/Black_bloc if you'd like to know more.

I'm pretty tired so i may have missed or written BS on top, please correct me if i am.
