Create a link that reveals a secret message only once. Perfect for private confessions or surprises.
A secret message link carries words you cannot un-send. An anonymous valentine to a coworker. A pregnancy reveal you want a partner to read at the moment they choose, not when their lock-screen pings mid-meeting. An apology to an estranged sibling. A disclosure to a counselor that the patient-portal cannot carry with the right tone. Each must reach one person, and after they read it the artifact has to stop existing.
Everyday channels betray that quietly. iMessage syncs to every device on a shared Apple ID, including the iPad any houseguest can wake. WhatsApp media auto-saves to the Android camera roll by default. Snapchat notifies on screenshot only after the capture has happened. An iMessage tap-back resurfaces the quoted line in later threads. Email keeps a copy in the sent folder as long as the account lives.
PasteOnce makes the message a single event, not a record. You write the note, generate a link, send it via whatever app the recipient uses, and the moment they open it the ciphertext is destroyed. Pair the TTL to the emotional half-life — an hour for a same-evening reveal, a day for a letter to find when they wake.
Client-side encrypted. We can't see your data.
Your data is encrypted in your browser before it leaves your device.
Messages are automatically deleted after being read once.
We never see your data. Only encrypted blobs pass through our servers.
Links work exactly once. Refresh the page and it's gone forever.
Your sensitive data is encrypted in your browser using AES-256-GCM. The encryption key is generated randomly and never sent to our servers.
Only the encrypted blob is stored in our database, with an automatic expiration time. We literally cannot read your data.
When your recipient opens the link, the encrypted data is fetched and immediately deleted from our servers using an atomic Redis GETDEL. The key in the URL hash decrypts the message in their browser.
Pick 1 hour when the recipient is awake and expecting to hear from you. Choose 6 hours for a surprise meant to land after dinner, 24 hours when you cannot predict pickup. Avoid 7 days — long links invite second readings that dilute the moment.
Avoid joint inboxes, shared streaming-account messages, or family group chats. A direct iMessage to the recipient's personal Apple ID, a one-to-one Signal thread, or a DM with disappearing mode all work. The routing channel leaks the context the link does not.
Ask the recipient to set Show Previews to When Unlocked on iOS, or hide sensitive content for messaging apps on Android. Carrier text becomes invisible to anyone glancing at the phone — which matters most for surprise reveals.
The note will not exist after they read it. There is no transcript to revisit, no evidence trail to lean on. Choose words you want them to carry; the version in their head is the one that survives.
You want to leave a Valentine without a paper trail or a Slack DM an admin can later export. Hand the coworker an envelope with only the link printed inside; the words exist for one reading, then are gone.
Your partner is on a work trip in another time zone. You want them to read alone in the hotel room, not when the phone pings at dinner with colleagues. PasteOnce the news with a 24-hour TTL: open when you are back tonight.
After a fight, you want the unguarded version — admitting things you would never say if you knew they could be forwarded around the family group chat. The link gives you room to be honest, knowing the artifact will not survive.
You want your counselor to know the gist of a hard topic before Tuesday's appointment, but the practice's patient-portal routes messages through an inbox shared with billing staff. PasteOnce delivers it out-of-band; they walk in already informed.
Not from the link — the URL has no identifying information, and our server cannot attribute it to you. Anonymity rides on the delivery channel. A printed note, a fresh email account, or a burner number carries it.
No read receipt by design — receipts would require tying the link to your identity. If you need to know, send a follow-up on your normal channel asking whether they got it. Trust beats telemetry for emotional content.
Nothing in any messaging app prevents a screenshot taken from a second device, and Snapchat only notifies after capture. Assume any reader who wants to keep the words can; the link removes default copy-and-archive behavior, not deliberate preservation.
No — for a keepsake, write it on paper or in a card. PasteOnce is the opposite of a keepsake; the message is gone the moment they read it. Use it for words meant to land once and dissolve.
