Sending a password, a private photo, or a sensitive note over regular chat or email means it sits in an inbox or backup indefinitely. Self-destructing message tools solve this — but not all of them work the way people assume. Here's what they actually do, and how to send one that includes an image, not just text.
The core idea: instead of sending the content directly, you send a one-time link. The recipient opens it, sees the content exactly once (or for a limited time window), and then it's permanently deleted from the server. Nobody — not even the person running the service — can read it after that point, and often not even during transit if the tool uses proper end-to-end encryption.
What these tools generally don't do: prevent the recipient from taking a screenshot before the content disappears, or protect anything once it's been read and copied elsewhere. Self-destruction protects against the message lingering somewhere unintended — not against a deliberate copy by the person you sent it to.
The best-known tools in this space — Privnote, One-Time Secret, Burn Note — all follow the same pattern: paste text, get a link, the link works once. They're free, require no account on either side, and are genuinely useful for sharing a password or a short sensitive note.
Their limitation: none of them natively support sending an image alongside (or instead of) text. If you need to share a screenshot — a QR code, a 2FA recovery screen, a scanned document — you're stuck attaching it separately through a channel that doesn't self-destruct, which defeats the purpose.
This is the actual gap: plenty of real-world sharing needs involve an image — a Wi-Fi password photographed off a router, a 2FA backup code as a screenshot, a private photo that shouldn't sit in someone's camera roll or chat history forever. Text-only self-destructing tools simply don't cover this case.
snote.domezos Secret Notes was built specifically to close that gap: a free, open-source Android app that extends the same self-destructing-link model to images (with or without accompanying text).
No account is required on either side — sender or recipient.
How long does the message stay visible?
Up to 60 seconds after the recipient opens the link. After that, it's automatically
cleared from the screen and permanently deleted from the server — there's no way to view
it again.
Does the recipient need an account?
No. Opening the link (or entering the short code) is enough; no sign-up, no app account
required.
Is the content encrypted, or just deleted after one view?
Both. The encryption/decryption happens client-side using the Web Crypto API with
AES-256-GCM — the server only ever stores ciphertext, never the plaintext or the key.
