Privacy Policy

Last updated: October 13, 2026

1. Introduction & Scope

Welcome to PromptGPT.io (operated by Monetiscope Services LLP). We respect your privacy and are committed to protecting your personal information. This Privacy Policy discloses our data collection, processing, and retention practices across our website, Chrome Extension, MCP connectors, and OpenAI Plugin integrations.

2. Specific Data Collected by OpenAI Plugin & MCP Tools

When you interact with our OpenAI Plugin, Custom GPT, or Model Context Protocol (MCP) server, we process the following data:

  • Tool Inputs: The prompt drafts, rough ideas, task instructions, and format parameters (e.g., target model, style, depth) that you explicitly provide to the optimizePrompt or generatePrompt actions.
  • Tool Outputs: The enhanced, structured, and formatted prompt text generated in response to your input.
  • Authentication & Session Data: Secure OAuth tokens or session identifiers used exclusively to verify active user status and manage unified credit balances.
  • Technical Diagnostics: Anonymized timestamps, latency metrics, and HTTP status codes for system reliability monitoring.

3. Purposes of Data Processing

We process collected data exclusively for the following purposes:

  • Prompt Engineering & Generation: To transform, expand, format, and optimize user instructions into structured prompts.
  • Credit Accounting: To accurately calculate and deduct unified credit balances per request.
  • Service Reliability: To diagnose errors, prevent abuse, and maintain server availability.

No Model Training: We do not sell your data, nor do we use your prompt inputs or generated outputs to train foundational machine learning models without your explicit, opt-in consent.

4. Data Recipients & Third-Party Processors

Data provided through PromptGPT tools is shared only with trusted, secure infrastructure providers necessary to fulfill your request:

  • AI Inference APIs: Leading enterprise AI providers (including Google Cloud / Gemini API and OpenAI APIs) via encrypted enterprise endpoints that uphold strict zero-data-retention or non-training agreements.
  • Cloud Infrastructure: Secure cloud hosting, database, and caching servers equipped with TLS 1.3 encryption in transit and AES-256 encryption at rest.

5. Data Retention & Deletion Policy

  • Prompt Processing In-Flight: Prompts submitted via MCP and plugin endpoints are processed in real-time in memory and returned immediately.
  • Account History: If you are a signed-in user, your generation history is saved to your personal dashboard for your convenience.
  • Retention Period: History logs are retained for as long as your account remains active, or until you choose to delete them. Technical server error logs are purged automatically every 30 days.

6. User Controls & Privacy Rights

You have complete control over your personal data:

  • Access & Export: You can view all saved prompts and generation logs directly from your PromptGPT dashboard at any time.
  • Right to Erasure (Delete Data): You can delete individual prompts from your history or delete your entire account and all associated data at promptgpt.io/delete-account.
  • Revoking Plugin Access: You can disconnect or revoke OAuth permissions for the PromptGPT plugin at any time via your OpenAI account settings.

7. Security Measures

We enforce strict organizational and technical measures to protect your data, including HTTPS/TLS 1.3 encryption across all API endpoints, parameterized SQL queries, strict SameSite cookies, and role-based access controls.
