HERAZUR LLC / PROMPT LIBRARY

Prompt Library privacy policy

Effective October 20, 2026

This policy explains how Herazur LLC (“we”, “us”) handles information in Prompt Library, our app of ready-to-use AI prompt templates and short lessons on writing prompts, where you can run a prompt with a real AI model and compare the answers. The app was previously called Prompt Academy. It is published on Google Play (package com.herazur.promptacademy).

Summary

• There is no account and no sign-in. We do not ask for your name or email address.
• When you run or improve a prompt, its text is sent through our server to Google’s Gemini API to generate the answer. Our server does not save your prompts or the answers.
• There are no ads, and the app has no analytics, crash-reporting, or advertising tools.
• Your progress and recent runs are stored on your device.

Information we collect

Prompts you run with AI

When you tap Run with AI or Improve, the app sends the prompt text (up to 4,000 characters), the mode, the selected template, any output options you chose, and the app language to our server. The server passes this to Google’s Gemini API and returns the answer to you. Our server does not store the prompt or the answer. Your last eight runs are kept on your device so you can see them again.

Install identifier and daily limits

On first launch the app creates a random install identifier. It is sent with each AI request so that we can count your daily free runs. Our server stores the number of runs per install identifier and day. To stop one network from using up the free service, it also counts runs per network using a salted, one-way hash of your IP address (for IPv6, of the network prefix); the IP address itself is not stored.

Reports about AI answers

If you report an AI answer as offensive, harmful, inaccurate, or other, we receive the prompt, the answer, the reason you chose, the app language, the app version, and your install identifier, so that we can review the report.

Purchases

If you buy Premium, Google Play processes the payment and we never see your card details. RevenueCat manages your subscription under a random identifier created by the app. When you run a prompt, our server asks RevenueCat whether that identifier has an active subscription so it can apply the Premium daily limit.

Support emails

If you contact support from the app, your email app opens with a message to us that already contains the app version, your device platform, and your install identifier, so we can find your reports or usage records. We receive whatever you send, including your email address.

Information that stays on your device

Your onboarding choices, lesson and quiz progress, daily goal and streak, your recent AI runs, purchase status, and settings are stored only on your device.

What we do not collect

We do not ask for your location, contacts, camera, microphone, or photos, and we do not use analytics, crash-reporting, or advertising tools.

AI-generated answers

Answers are generated by an AI model (currently Google Gemini) and can be inaccurate or incomplete. Check important facts before you rely on them. Do not enter passwords, payment details, health information, or other sensitive personal information in prompts, because the text is sent to the AI provider. You can report an answer from inside the app.

Permissions

Prompt Library does not request any device permissions such as camera, microphone, location, contacts, or photos. It uses the internet connection to run prompts and to check purchases.

How we use information

We use information to generate the AI answers you request; apply daily free and Premium limits and prevent abuse; provide and restore Premium; review reports about AI answers; respond to support requests; and meet legal obligations.

Service providers

We share information only with providers that process it on our behalf to run the app:

• Cloudflare (Workers and Durable Objects): hosts our server, receives your requests and IP address, and stores the daily run counters and reports described above.
• Google Gemini API: the prompts you run or improve, and the options sent with them.
• RevenueCat: subscription status and purchase history, linked to a random identifier.
• Google Play: app distribution, in-app purchases, and the in-app review prompt.

We may also disclose information if required by law or to protect the rights, safety, or security of our users or others. We do not sell personal information or share it for cross-context behavioral advertising.

Where data is processed

Our server runs on Cloudflare’s global network, and our service providers may process data in the United States and other countries. Where required, transfers rely on appropriate safeguards such as the providers’ standard contractual clauses.

Retention

• Prompts and answers are not stored on our server. Google may keep Gemini API requests for a limited period under its own terms.
• Daily run counters are deleted after about 3 days. The record of which days an install identifier used live AI is deleted after about 35 days.
• The cached Premium check for a RevenueCat identifier is deleted within a day.
• Reports about AI answers are deleted after one year.
• Cloudflare keeps short-term technical request logs for its standard retention period.
• Data on your device stays there until you clear the app’s storage or uninstall it. Purchase records held by Google Play or RevenueCat may be retained as the law requires.

Deleting your data

Prompt Library has no accounts, so there is no account to delete. To remove everything stored on your phone, open your device’s Settings → Apps → Prompt Library → Storage → Clear storage, or uninstall the app. The run counters on our server are linked only to a random install identifier and expire on their own as described above.

To have reports you sent, or any other data linked to your install identifier, deleted sooner, email support@herazur.us with the subject “Prompt Library data deletion”. Include your install identifier, which appears in the email the app prepares when you tap the support email link. Earlier versions of the app offered sign-in with an email address; if you created an account then, write to the same address from that email address and we will delete it.

Deleting your data does not cancel a Premium subscription: cancel it in Google Play under Payments & subscriptions → Subscriptions.

Your rights

Depending on where you live, you may have the right to access, correct, export, or delete your personal information, to object to or restrict certain processing, and to withdraw consent. You can view and edit most of your information in the app. For other requests, contact us at the address below. We aim to respond within 30 days and will not discriminate against you for exercising your rights. You may also complain to your local data protection authority.

Security

Data is encrypted in transit. The AI provider key is kept on our server and is never included in the app, and IP addresses are stored only as salted hashes. No method of transmission or storage is completely secure.

Children

Prompt Library is intended for users aged 18 and over and is not directed to children. We do not knowingly collect personal information from children. If you believe a child has provided us information, contact us and we will delete it.

Changes to this policy

If we change how we handle information, we will update this page and its effective date and, for significant changes, tell you in the app.
