Privacy Commitment
PromptEngine is built to help you write better prompts without treating your ideas as a product to resell or mine for advertising. We collect only what we need to run the service, protect your account, and improve reliability. This page describes how we handle information when you use our website and Chrome extension.
Data Storage
We do not log or retain the full text of your prompts for analytics, model training, or resale. When you use optimization features, your input may be processed in real time to return a result; it is not kept as a permanent log tied to your identity for those purposes. Operational safeguards (such as short-lived error diagnostics) are limited to what is necessary to keep the service secure and stable.
Account Data
If you create an account, we store only what is needed to identify you and manage your subscription: for example, your email address and plan or billing status supplied by our payment provider. We do not use this information for unrelated profiling.
Email Marketing
When you create an account, you can choose to receive product updates, tips, and occasional offers from PromptEngine. If you opt in and verify your email, we sync your address to our email provider (Lemon Squeezy) so we can send those messages. You can unsubscribe from any marketing email using the link in that message.
Marketing emails are separate from transactional messages (such as email verification or password reset). We do not sell your email address to third-party advertisers.
No Third-Party Advertising
We do not run third-party advertising networks on PromptEngine, and we do not sell your personal information to data brokers. If we ever introduce optional integrations that share data outside this policy, we will update this page and, where required, ask for your consent.
Local Processing
Parts of the experience—such as UI state, preferences, or draft text you have not yet sent—may remain on your device in browser storage until you clear it. Our Chrome extension operates in the context of supported AI sites only for the features you trigger; it does not silently read unrelated tabs or harvest browsing history for marketing.
