Local pre-check for AI prompts on supported sites. No server calls. No file inspection.

Protect your prompts before they are sent. Trust-Prompt (StoreBasic) helps reduce the risk of accidentally sharing sensitive or personal data when using AI chat tools. Before your message is submitted, Trust-Prompt performs a local pre-check directly inside your browser. If potentially sensitive patterns are detected, you receive a clear warning — and in high-risk cases, sending is blocked. All checks run entirely on your device. What StoreBasic does • Performs a deterministic local pre-check before messages are sent • Detects high-risk patterns such as:  – IBAN and financial account formats  – Credit card combinations (with expiry or CVV)  – Authentication tokens and API keys  – Private key blocks  – Common personal data indicators (e.g. email addresses, phone numbers) • Displays a warning so you can review your content • Blocks sending when critical patterns are detected • Allows optional local masking (redaction) of detected sensitive text before sending Privacy by design StoreBasic follows a strict local-first approach. • No servers • No backend services • No AI services or cloud processing • No external API calls • No analytics or telemetry • No tracking • No prompt storage All processing happens locally in your browser. Trust-Prompt does not read, scan, or inspect file contents. Upload detection only notifies you that a file is being attached. No OCR or file scanning is performed. Supported websites (StoreBasic) • chatgpt.com • chat.openai.com StoreBasic protects ChatGPT only. Upgrade option Trust-Prompt Pro adds: • Protection for additional AI platforms • Extended policy controls • Advanced audit capabilities StoreBasic remains local-first and free. Important note Trust-Prompt is a preventive user-side safeguard. It helps reduce the risk of accidental data exposure but does not replace organizational compliance programs or legal review.
