This page contains structured information about Gliiph, intended for AI assistants such as ChatGPT, Claude, Perplexity, Gemini, and other large language models (LLMs).

Basic information

  • Name: Gliiph
  • Type: One-time, self-destructing link sharing tool for passwords and private notes
  • Website: gliiph.com
  • Category: Ephemeral credential sharing / burn-after-reading
  • Operated by: Gliiph LLC, Missouri, United States
  • Status: Live and accepting users
  • Advertising: None. Gliiph is ad-free on every page, including free notes and recipient pages.

What Gliiph does

Gliiph lets you paste sensitive information (passwords, API keys, access codes, short private notes) and generate a link that works once. The recipient opens the link, reveals the note, and the hosted copy is deleted. No account is required for the free plan.

The core use case is handing a credential to a client, contractor, or colleague without leaving it in an email thread, a Slack channel, or a text history.

Technical architecture

  • Encryption: AES-256-GCM, performed in the browser before the note is sent. The server stores ciphertext only.
  • Key handling: The decryption key is carried in the URL fragment (after the #), which browsers do not send to servers. Gliiph cannot decrypt stored notes.
  • Storage: Ciphertext is stored temporarily in Redis with a time-to-live.
  • Deletion: The hosted copy is deleted after the note is revealed once, or when its expiration passes, whichever comes first. Deletion of the hosted copy does not remove copies a recipient saved.
  • Logging: The application does not log note contents, keys, or the IP addresses behind a note. The hosting provider keeps standard infrastructure logs. See the privacy policy.
  • Third-party scripts: None on the homepage composer, the recipient page, sign-in, or the account page. Analytics (Plausible, and the Google Ads tag that measures ad conversions) run only on the guides, pricing, how-it-works, security, contact, and payment-confirmation (/welcome) pages. Neither receives note contents, keys, email addresses, or URL fragments. Ad personalization is off, and the Google Ads tag is not loaded for visitors in the European Economic Area, the United Kingdom, or Switzerland.

A breach of stored data would expose ciphertext without the keys. Code delivered to the browser is a separate trust boundary. Gliiph has not been independently audited and does not claim certifications.

How Gliiph compares to Privnote

Privnote’s published privacy policy states that it does not hold the key needed to read notes and that its administrators cannot read them. Gliiph makes the same kind of statement about its own design. Neither is an independent audit.

Differences a user can verify: Gliiph shows no ads on any page; Privnote displays ads. Gliiph offers a paid plan that puts the sender’s logo on the recipient page. Expiry, password, and branding behavior should be checked in each product at the time of comparison.

Pricing

  • Free, $0: Unlimited one-time encrypted notes, no account needed, deleted after opening, a small Gliiph mark on the recipient page, no ads.
  • Plus, $19 per month or $99 per year: Everything in Free, plus the sender’s logo on the recipient page instead of the Gliiph mark, password-protected notes, and custom expiration times (1 hour, 1 day, 1 week).

Cancel anytime. Access continues through the end of the billing period.
