How to Set Up a 'Dead Man's Switch' Text Archive for Personal Safety

Here's a scenario that isn't hypothetical — it happens every day:

A woman is receiving increasingly threatening texts from an ex. She's documenting everything, saving screenshots on her phone. She's told friends about the situation. She's filed a police report.

Then her phone is stolen. Or confiscated. Or smashed. And every piece of evidence she'd collected goes with it.

A "dead man's switch" text archive solves this. It's a simple concept: every text message you receive is automatically, silently, and continuously forwarded to an email address controlled by someone you trust. If your phone is taken, destroyed, or you're unable to use it — the record already exists somewhere else. And it's been building itself, silently, every single day.

What Is a Dead Man's Switch (In This Context)?

The term comes from industrial safety: a mechanism that activates when the operator fails to take action. In personal safety, the concept is similar — you create a system that preserves evidence continuously, so that if you're incapacitated, the evidence doesn't die with your phone.

Your SMS dead man's switch:

• Runs silently — the person threatening you has no idea it exists
• Runs continuously — every text, from everyone, is archived
• Lives off-device — the archive exists on someone else's email, inaccessible to your attacker
• Requires no daily action — once set up, it works forever

Who Needs This

How to Set It Up (5 Minutes)

Step 1: Choose Your Trusted Recipient

This is the most important decision. Pick ONE person:

• A close friend you trust absolutely
• Your attorney
• A family member in a different city
• A domestic violence advocate or case worker
• Yourself — a secondary email on a separate device that your attacker doesn't know about

Critical: This person should understand what they're receiving and why. Brief them: "I'm setting up an automatic archive of my text messages. If anything happens to me, this inbox contains every text I've received. Don't delete anything."

Step 2: Create a Dedicated Email

Don't use their everyday inbox — the volume will be overwhelming. Create a new address:

• [yourname][email protected]
• [yourname][email protected] (end-to-end encrypted — recommended)

ProtonMail is strongly recommended for safety situations — even if someone gains access to your Google account, they can't read ProtonMail emails stored in your trusted person's inbox.

Give this email's login credentials to your trusted person. Or set up forwarding from this inbox to their personal email.

Step 3: Install SMS to Email Forwarder

Download SMS to Email Forwarder on your iPhone.

1. Enter the safety archive email address
2. Complete the Shortcuts setup — 2 minutes
3. Once configured, the app works silently in the background

The app does not show any on-screen notifications when forwarding. There is no visual indicator that messages are being archived. This is by design.

Step 4: Verify It Works

Have a friend send you a test text. Check the archive email — it should arrive within seconds. Then delete the test to keep the inbox clean.

Step 5: Lock Down the App

• Move the app into a folder where it won't be noticed (Utilities, or a second screen)
• If you're concerned about someone checking your phone: iOS allows you to hide apps from the Home Screen entirely (long press → "Remove App" → "Remove from Home Screen"). The app continues running.

Operational Security: Keeping the Archive Secret

If you're in a dangerous situation, the person threatening you must not discover the forwarding. Here are precautions:

On Your Phone

• Hide the app from Home Screen (it still runs via Shortcuts)
• Don't name the Shortcuts automation anything obvious — rename it to something innocuous like "Focus Mode" or "Battery Saver"
• Turn off mail notifications for the archive email if it's installed on your phone
• Don't tell anyone except your designated trusted person

On the Email Side

• Use a separate email not linked to any account your attacker might access
• ProtonMail is preferred — free, end-to-end encrypted, based in Switzerland
• Don't access the archive email from your phone if possible — your trusted person should be the one checking it
• Enable 2FA on the archive email account

If Your Phone Is Inspected

The Shortcuts automation will show up in the Shortcuts app. If you're worried about inspection:

• The automation appears as "When I receive a message" → "Run Forward SMS"
• You can rename the action label to something less descriptive
• The email address you're forwarding to is visible in the Shortcut action — this is the most exposing element
• Consider using a code-name email address that doesn't reveal the recipient (e.g., [email protected])

What to Do When Something Happens

If the situation escalates and you need to use the archive:

For Law Enforcement

1. Your trusted person logs into the archive email
2. They can export all emails as PDF or print them
3. Each email contains: sender's phone number, message content, timestamp
4. Email headers provide additional authentication metadata
5. Present to law enforcement as a continuous, unedited record

For Your Attorney

1. Grant your attorney read access to the archive inbox
2. They can filter by date range, sender number, or keywords
3. The continuous, automatic nature of the archive demonstrates that evidence wasn't selectively collected

For a Restraining Order

• Show the judge the archive inbox with months of continuous forwarding
• The fact that ALL texts were forwarded (not just threatening ones) proves you weren't cherry-picking
• Email timestamps are independently verifiable, unlike screenshots

Set It Up Before You Need It

The hardest truth about personal safety tools: they only work if you set them up before the crisis.

No one thinks they'll need a text archive until the phone is already gone. No one plans for evidence until the court date is already on the calendar.

Five minutes. One app. One trusted email address. A continuous, silent, unbreakable record that survives anything that happens to your phone.

For specific legal situations, see our guides on documenting harassment texts, domestic violence evidence, and stalker documentation.

Your safety shouldn't depend on your phone surviving.
