Welcome to PromptLib! Our app gives you access to a curated gallery of AI image prompts and a Workspace where you can test them out on your own photos. We want you to create with complete peace of mind: PromptLib does not use user accounts and contains no tracking or analytics SDKs. The only external service we rely on is Google AdMob to show ads (more details below).
When you hit Generate, your photo is first resized locally on your device (keeping the longest edge at 512 px) so it travels quickly and securely over HTTPS alongside your prompt text. Our server immediately forwards everything to Cloudflare Workers AI (powered by the FLUX.2 [klein] model from Black Forest Labs) to create your edited image, and sends it straight back to your device. Rest assured: our server never saves your photo, your prompt, or the final result. Cloudflare handles these requests strictly under its own terms and privacy policy.
Your newly created image lives temporarily in the app's cache. It will only ever be written to your device gallery if you explicitly tap Save, and it leaves your device only if you choose to share it.
To keep PromptLib free and accessible for everyone, we display banner ads, full-screen ads, and rewarded videos via Google AdMob. To serve and measure these ads properly, Google may collect and use your device's advertising ID, IP address, and standard usage information, and may personalize ads where permitted. Whenever required by local laws (such as in the EEA, the UK, and Switzerland), the app will present a consent form when you first open it. You can update your choices at any time directly from the menu at the top of the Gallery (under Ad privacy choices) or via your device settings. For more information on how Google manages this data, please check out policies.google.com/technologies/ads.
PromptLib does not sell your personal information for money. However, letting Google use your device's advertising ID and related data to personalize ads may count as a "sale" or "sharing" of personal information, or as "targeted advertising", under the privacy laws of some US states (for example California, Colorado, Connecticut, Virginia and Utah). If you live in one of these states, you can opt out at any time with Ad privacy choices in the menu at the top of the Gallery, which opens Google's opt-out form; you can also delete or reset your advertising ID in your device's settings. PromptLib keeps no personal data on its servers, so there is nothing else to access or delete; for any request, contact us at the address below. You will not be treated differently for using these rights.
To give you a smooth experience, the app stores a few lightweight items locally on your phone: your daily generation counter (along with any extra bonuses earned from rewarded videos), a pacing counter for full-screen ads, a cached copy of the prompt gallery so you can browse offline, timestamps for your unlocked prompts (each unlock lasts 24 hours), and a local history log containing small thumbnails of your successful generations, the prompts used, and dates. This history stays strictly on your device, is never uploaded anywhere, and can be cleared or managed item-by-item directly from the History screen. Nothing else is kept behind.
Our prompt gallery is fetched dynamically from a public GitHub repository. Whenever the app loads or refreshes the gallery, GitHub naturally receives your IP address and standard request data.
If you choose to use our contributor feature to submit a new prompt, the image, title, category, tags, and text you provide are uploaded for review. If approved, they will be published publicly in that same GitHub repository. Please make sure not to submit anything you wouldn't want to be public!
We only ask for device permissions when you need them: Camera access is used only when you tap the Camera button; photo selection uses the system picker so PromptLib only sees the single image you explicitly choose; and gallery write access is requested only when you tap Save.
PromptLib is not designed for children under 13, and we do not knowingly collect any data from them.
We may occasionally update this policy to reflect new features or changes. The date at the top always shows the latest version. If you have any questions, we'd love to hear from you at Toavina.supportclient@gmail.com.
