Why not just turn on "Disappearing Messages" in WhatsApp or Signal?

Built-in disappearing messages are a great feature, but they usually apply to the entire conversation thread for both people, rather than a single sensitive piece of text. Also, if the timer is set to 7 days or 24 hours, the message still remains visible and readable during that window. A single-view secret link burns immediately after reading without changing your conversation settings.

Does the recipient need to download an app or create an account to view the link?

No. The recipient simply taps the link to open it in their standard phone or computer browser (Safari, Chrome, Firefox, etc.). No account creation, software download, or registration is required.

What kinds of private information are best suited for expiring links?

Anything you want someone to see right now but don't want saved in your conversation history: surprise gift ideas, personal Wi-Fi passwords, lockbox codes, medical notes, temporary access PINs, or private instructions.

Can I add an extra password or PIN to my secret link?

Yes. You can optionally require a separate passphrase to unlock the secret. You can tell your recipient the passphrase over a quick phone call, ensuring that only they can decrypt and open the message even if someone else intercepted the link.

How do I know the private information is really gone from your servers?

Paste & Purge uses zero-knowledge browser-side encryption (AES-256-GCM). The decryption key is in the URL hash fragment after the # symbol, which is never sent to our servers. Once the secret is viewed or the expiration timer elapses, the encrypted database record is permanently purged from memory and storage.

What is the easiest way to share a private note right now?

1) Paste your text into the box on the home page, 2) Choose your expiration time (e.g. 1 hour or 1 view), 3) Click "Create Secret Link", 4) Copy the link and paste it into your normal chat. Done.

Everyday Privacy Guide

How to Send Private Information Without Leaving It in Your Messages

Published by Paste & Purge·Communication Privacy·7 min read

Sometimes you need to share something personal with a friend, family member, or coworker:

A temporary door or lockbox code for an afternoon visit.
A private surprise birthday plan or gift idea.
A home Wi-Fi password or streaming account login.
A sensitive medical question or personal instruction.

You want them to read it right away. But you don't want those words sitting in your permanent text history for the next three years.

Why Normal Messages Linger Forever

Standard messaging apps are designed for archiving. They want you to be able to scroll back to 2019 to find an old recipe or remember a restaurant recommendation.

While that is great for everyday banter, it means anything sensitive you type into a chat thread gets preserved across:

Chat History

Searchable by anyone who holds either unlocked phone.

Linked Devices

Synced to laptops, tablets, and smartwatches automatically.

Cloud Backups

Stored in phone backup archives indefinitely.

The Cleaner Alternative: Single-View Secret Links

Instead of typing the sensitive information directly into the chat box, you use an expiring link. Here is how it works in four simple steps:

1Paste Your Text on Paste & Purge

Type your private note or password into the box. Choose an expiration (like 1 hour or 1 view).

2Encrypted in Your Browser

Your browser encrypts the secret before it leaves your device. The server only sees an unreadable scrambled string.

3Send the Link in Your Chat

Copy the generated link and text it to your recipient. Your chat thread only contains an expiring URL, never your actual secret.

4Revealed Once, Then Burned

The recipient opens the link in their web browser, reads your message, and the secret is immediately deleted from the database.
