Privacy Policy

Promptron is built so your content does not reach Promptron's servers. Generation uses Bring Your Own Key (BYOK): when you choose to use AI features with an Anthropic API key, requests are sent directly from your device to Anthropic under your own API key. We do not collect, transmit to ourselves, sell, share for advertising, or use your content for Promptron training.

What Is Stored and Where

• Anthropic API key: stored in the iOS/macOS Keychain using this-device-only accessibility where available. It leaves the device only as the x-api-key header in requests to Anthropic.
• Workspace: stored locally on your device, including account display name, projects, conversations, prompt text, generated prompt text, scores, and local account metadata.
• Local account password: stored locally as a derived hash, not plaintext.
• Sign in with Apple account record: stored locally when you use Apple authentication, including Apple's account identifier and any name or email Apple returns.
• Generation cache: stored locally to avoid repeated identical calls.
• Subscription state: cached locally; real purchase status is handled by Apple when App Store purchases are configured.
• AI data sharing consent: stored locally so the App knows you have agreed before AI requests are sent to Anthropic.

What May Be Sent to Anthropic

Before the App sends AI requests to Anthropic, it shows an in-app permission notice. If you agree and use AI features, the following data may be sent directly from your device to Anthropic:

• The text you type into the composer.
• Relevant local conversation context and any standing context you saved.
• Text extracted locally from attachments you choose, such as txt, markdown, HTML, PDF, docx, or xlsx files.
• Image attachment data when BYOK Vision is available and you choose to include images.
• Generated prompt candidates and evaluation candidates needed to produce or score the result.

How Data Is Collected and Used

The App reads the content above only from your on-device workspace, text you enter, files or images you explicitly select, links you paste, and account/authentication actions you initiate. It uses this data to generate prompts, ask clarifying questions, read selected references, evaluate results when enabled, maintain local conversations, authenticate the local account, and unlock App Store purchases. Promptron does not receive this data on a Promptron server.

What We Do Not Do

We do not run analytics, advertising, tracking, third-party SDKs, or server-side content storage. We do not log your Anthropic API key or prompt content.

Third-Party Processing

Anthropic receives AI request data directly from your device only after your in-app permission and only when an Anthropic-backed AI feature is used. Anthropic's handling of that data is governed by Anthropic's privacy policy and terms; Anthropic states its API services are designed to provide confidentiality and security protections for customer content. Purchases and Sign in with Apple are handled by Apple.

Your Rights and Choices

You can access and delete local workspace data from your device by using in-app controls where provided or deleting the App. You can remove your local API key in settings. Where GDPR, UK GDPR, CCPA/CPRA, the Australian Privacy Act 1988, or other privacy laws apply, contact us about access, deletion, correction, portability, objection, or complaint rights. You can decline the AI data sharing permission; in that case the App will not continue the AI action that would send data to Anthropic.

Children

Promptron is not directed to children under the age of digital consent in their jurisdiction and is not intended for users under 16 unless local law permits a lower age with valid consent.
