# 💻 Digital Hygiene 2025

**The Step-by-Step Guide to Cleaning, Securing & Hardening Your Online Life**

If you breathe internet for a living, this is your shower.  
You’ll dig up every old account, wipe trackers, encrypt your stuff, and end with a setup so clean it squeaks.  
No vague “just use a VPN” nonsense — real steps, real commands, zero fluff.

* * *

## 🎯 Goal

By the end, your devices, browsers, and clouds will be **clean, encrypted, minimal, and easy to recover**.  
You’ll _actually_ be private — not just pretending.

* * *

## 👥 Who’s It For

Freelancers, devs, creators, researchers — anyone with sensitive data or who uses AI or cloud tools daily.

* * *

## 🧩 Overview

You’ll go through six phases:

1. **Scan & Inventory** – find what exists.
2. **Purge & Clean** – delete junk and risk.
3. **Secure** – lock accounts and devices.
4. **Encrypt** – protect what stays.
5. **Automate & Backup** – set safety nets.
6. **Harden & Maintain** – build lasting privacy habits.

* * *

## 🧠 PHASE 1: Scan & Inventory Everything

**Step 1 – Build Your “Digital Map”**

Create `Digital-Inventory.md`:

```auto
| Category | Account/Service | Last Active | Data Stored | Risk | Notes |

```

List emails, clouds, socials, dev platforms, payment sites, subscriptions, AI tools.  
💡 Tip: export account lists from your password manager for speed.

* * *

**Step 2 – Scan Local + Cloud Storage**

**Windows**

```auto
Get-ChildItem -Recurse C:\Users\<you>\Documents | Sort-Object Length -Descending | Select -First 20

```

**macOS/Linux**

```auto
du -ah ~/Documents | sort -rh | head -20

```

Search Drive/Dropbox/iCloud for `.zip`, `.csv`, `.pdf`, `backup`, `password` — flag sensitive files.

* * *

**Step 3 – List Devices**  
Check each major account → _Security / Devices_ → sign out of everything except your current ones.  
Copy device list into your inventory.

* * *

## 🧹 PHASE 2: Purge & Clean

**Step 4 – Delete Stale Accounts**

Unused \> 12 months?  
Export → Delete → Mark “Purged.”  
👉 [JustDelete.me](https://justdelete.me) gives direct links.

* * *

**Step 5 – Clean Inbox + Tracking**

Use **Cleanfox** , **LeaveMeAlone** , or **[Unroll.me](http://Unroll.me)** to mass-unsubscribe.  
In Gmail:

```auto
has:attachment older_than:1y

```

Delete or archive old junk.  
Optional: auto-archive `older_than:2y`.

* * *

**Step 6 – Browser Detox**

1. Clear cookies & cache.
2. Add **uBlock Origin** , **Privacy Badger** , **ClearURLs** , **Decentraleyes**.
3. Search via **DuckDuckGo** , **Startpage** , or **Brave Search**.
4. Block third-party cookies.
5. Delete saved passwords → import into a manager.  
💡 Separate profiles (Work / Personal / Banking) or Firefox Containers.

* * *

## 🧱 PHASE 3: Secure Everything

**Step 7 – Password Fortress**

Use **Bitwarden** , **1Password** , or **Proton Pass**.  
Import creds → run audit → fix weak ones → enable 2FA → store recovery codes offline.

* * *

**Step 8 – Hardware Security & Passkeys**

Passwords are so 2020s.

- Get **2 FIDO2 keys** (YubiKey, Token2, Thales).
- Register with Google, Microsoft, GitHub, banks.
- Keep the backup key in a fireproof safe.
- Prefer **device-bound passkeys** over cloud-synced ones for max safety.

* * *

**Step 9 – Phone Number Privacy**

Your SIM is your skeleton key.

- Use virtual numbers ( **MySudo** , **Hushed** , **Google Voice** ) for sign-ups + 2FA.
- Keep real number only for banks / gov / family.
- Ask carrier for SIM-swap protection or port freeze.
- Pick VoIP providers with TLS/SRTP encryption.

* * *

**Step 10 – Social Engineering Defense**

Humans are the weakest link.

- Watch for urgency / fear / authority traps.
- Verify requests via known channels, not the caller’s.
- Run monthly phishing drills (KnowBe4, Cofense).
- Golden rule: **“Verify then trust.”**
- Practice saying _“I’ll call you back.”_

* * *

## 🔒 PHASE 4: Encrypt Everything

**Step 11 – Encrypt Local Files**

Use **VeraCrypt** or **Cryptomator**.

```auto
Name: Personal_Secure
Size: 5 GB
Encryption: AES-Twofish-Serpent

```

Keep IDs, contracts, recovery codes, seeds, taxes inside.  
Mount → use → unmount.

* * *

**Step 12 – Encrypt Cloud Data**

Encrypt before upload with **Cryptomator** or **rclone + encryption** :

```auto
Drive/
 └─ Encrypted_Vault/ (mounted via Cryptomator)

```

Everything stays encrypted in transit and at rest.

* * *

**Step 13 – Metadata Scrubbing**

Every photo or PDF tattles on you.  
Use **ExifTool** , **ExifCleaner** , or **Scrambled Exif** to strip GPS, timestamps, and device data.  
Also clean PDFs (author names, revisions).  
💡 Automate via Hazel / Automator before upload.

* * *

## ⚙ PHASE 5: Automate & Backup

**Step 14 – Local Backups**

Use **Duplicati** , **Restic** , or **BorgBackup**.

```auto
restic init --repo /mnt/backup_drive
restic backup ~/Documents
restic forget --keep-last 5 --keep-monthly 3

```

Schedule weekly.

* * *

**Step 15 – Cloud Backups**

Pick one for redundancy:  
**Backblaze** , **Proton Drive** , or **pCloud** (with versioning + zero-knowledge).

* * *

**Step 16 – Auto Data Exports**

- **Google Takeout** – every 3 months
- **GitHub** – mirror via cron/Actions
- **Socials** – export quarterly
- Store in your encrypted vault (date-labeled).

* * *

## 🧰 PHASE 6: Harden & Maintain

**Step 17 – Secure Network**

- Update router firmware.
- Change admin password.
- Enable WPA3 + guest network.
- Use DNS: **NextDNS** , **Quad9** , **Cloudflare 1.1.1.1**.
- Disable UPnP / WPS.
- Test leaks → [dnsleaktest.com](https://dnsleaktest.com).  
💡 Bonus: Pi-hole or AdGuard Home = LAN-wide ad-block.

* * *

**Step 18 – Harden Devices**

**Windows:** BitLocker, O&O ShutUp10, Full Scan  
**macOS:** FileVault, disable web Spotlight, audit LaunchAgents (KnockKnock)  
**Linux:** UFW / Firewalld, encrypt /home  
**Mobile:**  
Android – full-disk encryption + F-Droid  
iOS – Lockdown Mode + disable ad tracking

* * *

**Step 19 – AI-Specific Privacy Risks**

Your prompts are not private.

- Opt out of AI training (OpenAI, Anthropic, Google).
- Use local LLMs ( **Ollama** , **LM Studio** ) for sensitive work.
- Never paste proprietary code or PII into web AIs.
- Review provider retention policies quarterly.
- Be aware: AIs can “remember” your inputs months later.

* * *

**Step 20 – Supply Chain & Hardware Risks**

- Never plug unknown USBs or “found” drives.
- Buy hardware direct from manufacturers.
- Check Device Manager for unknown input devices quarterly.
- Confirm TPM / Secure Boot enabled in BIOS.
- Avoid cheap cables that hide malware chips.

* * *

**Step 21 – Privacy-Enhancing Tech (PETs)**  
(For power users)

- **Zero-knowledge proofs** – prove without revealing.
- **Homomorphic encryption** – compute on encrypted data.
- **Federated learning** – train AIs without centralizing data.  
Worth knowing as they go mainstream.

* * *

**Step 22 – Continuous Monitoring**

- [Have I Been Pwned](https://haveibeenpwned.com)
- **Firefox Monitor**
- **Bitwarden/1Password Watchtower**
- **Cloudflare Radar**  
📅 Reminder: “Digital Checkup – 1st Sunday Monthly.”

* * *

## 🗓 Maintenance Routine

| Frequency | Action | Tool | Time |
| --- | --- | --- | --- |
| Daily | Close tabs, sign out | Browser | 5 min |
| Weekly | Delete downloads, run AV | OS Tools | 15 min |
| Monthly | Audit passwords + verify backups | Bitwarden / Duplicati | 30 min |
| Quarterly | Revoke app access + data minimization review | Browser + API | 1 hr |
| Bi-Annual | Check privacy policy updates (ToS;DR) | Browser | 30 min |
| Yearly | Threat model review – “Who wants my data & why?” | Notebook | 1 hr |

* * *

## 🤖 Automation Extras

**Auto-Delete Junk Downloads**

Windows:

```auto
Get-ChildItem "$env:USERPROFILE\Downloads" -Include *.crdownload,*.tmp,*.part -Recurse | Remove-Item -Force

```

macOS/Linux:

```auto
find ~/Downloads -type f \( -name "*.crdownload" -o -name "*.tmp" -o -name "*.part" \) -delete

```

**Email Yourself a Monthly “Privacy Report Card”**  
Use Make or Zapier → trigger monthly → pull weak-password + 2FA stats → send:

> “Privacy Score 8/10 – 5 weak passwords left.”

* * *

## 🧰 Real-World Example

**Before:**  
Freelancer with 4 clouds, 7 AI tools, weak passwords, auto-login everywhere, trackers galore.

**After:**

- 2 clouds + encrypted vaults
- Unique passwords + 2FA
- Local + cloud backups automated
- Browser sandboxed
- Monthly privacy report

➡ 90 % less exposure, 0 credential leaks in 6 months.

* * *
