promptLib privacy

Live at promptlib.llab08.com. A prompt library served from the studio server behind Cloudflare. The public gallery is read-only; the Studio is a private tool that only llab08 can unlock.

This service is operated by llab08, Hong Kong, and these terms are governed by the laws of Hong Kong. The section below explains this product’s data handling and current availability.

Data this product handles

• The public gallery has no accounts, no sign-in and no forms. It only answers read requests and stores nothing you send; a search term travels in the page address and therefore appears in the access log like any other request.
• The public gallery sets no cookies. The page keeps one localStorage key on your device, promptlib.uiLocale, holding the interface language you picked. Clearing the site’s data in your browser removes it.
• Server logs: the application container keeps standard access logs (request path, time, status and the client address as seen by the server). They rotate automatically and are used only to run the service and to investigate abuse. Cloudflare proxies the hostname and processes connection data under its own privacy policy.
• Rate limiting keeps a short-lived, in-memory count of requests per client address (about one minute). It is never written to disk.
• No analytics scripts. As of the date below the site loads no Google Analytics, gtag, Umami, Plausible or any other third-party analytics script or font. If that ever changes, this section is updated first.
• Images: available example images are served from our gallery host. Loading them sends ordinary image requests to that host; it does not upload images from your device or call an image-generation model. Source and attribution links accompany the prompts. Attribution does not grant permission to reuse an image; check the rights stated by its source.
• Links to upstream galleries, repositories and original posts lead to third-party sites with their own policies.

Studio (private, llab08 only)

• The Studio page (/studio, linked from the gallery) is llab08’s own tool for writing image prompts and translations. It shows an access-code form and does nothing until a valid code is entered. There are no Studio accounts and no sign-up.
• Access-code form: the code you type is sent to our server, compared with the configured code and not stored. To slow down guessing, sign-in attempts are counted per client address in memory for five minutes; the count is never written to disk.
• Session cookie: a correct code sets one cookie, promptlib_studio (HttpOnly, Secure, SameSite=Strict, sent only to /api/studio). It holds an expiry time, a random value and a signature, no personal data, and lasts 24 hours or until the Studio is locked. While the Studio is open, the tab also keeps the ID of the job being watched in sessionStorage (promptlib.studio.job), which the browser clears when the tab closes.
• AI processing: images uploaded to the Studio, catalog images and prompt text it is pointed at, and any instructions typed there are sent to an AI model provider (Grok models from xAI) through a relay that llab08 runs on its own server. The provider processes them under its own terms.
• Studio history: each job’s inputs, including uploaded images, and its results are kept in the Studio’s database on our server so they can be reviewed and retried. There is no automatic deletion yet: they stay until llab08 deletes them. Studio output reaches the public site only when llab08 publishes it, for example prompt translations and the Examples page.

Advertising

The site shows no advertising today and loads no advertising script. When advertising is added it will appear only on list and gallery pages, and this section is updated to name the ad provider and describe the consent step before the first ad request is made.

Prompt licences

Prompt text is mirrored from community libraries and keeps the licence or terms of the source it came from:

• CC BY 4.0 for the curated repositories;
• MIT for the pinned full-corpus repositories;
• the curator’s Attribution Required License v1.0 for the Shuixian collection (水仙的AI提示词): non-commercial use with credit and a link to the source, and commercial use only with the curator’s written permission. The curator claims no rights over the collected texts and images, which remain with their original authors;
• no stated licence for the PixelForge catalog snapshot or the NewBananaPrompts 3D Render gallery.

Every source, with the pinned commit where the source is a repository, is listed on the attribution page, and the licence of a single prompt is printed on that prompt’s page.
