Privacy Policy

Prompt Cost Calculator is built to keep prompt analysis lightweight and privacy-conscious. This page explains what the app processes locally, what limited analytics may be stored, and what users should keep in mind before pasting content into the tool.

Local prompt processing

Prompt Cost Calculator processes prompts locally in the browser. The estimator, token heuristics, scenario logic, and comparison views are designed so the app does not need to intentionally send raw prompt text to a backend just to generate the on-page estimates.

Uploaded .txt files are read locally in the browser and used to populate the existing prompt field. The app is not designed to upload file contents as files or store the original text as part of its analytics records.

What the app does not intentionally store

The app does not intentionally store prompt text, uploaded file contents, filenames, or exact character counts in its application analytics table.

The app is designed to use privacy-safe bucketed analytics values instead of raw prompt data. Those limited metrics help the site understand usage patterns without storing the full substance of what a user pasted.

Privacy-safe analytics and service providers

The app may store privacy-safe analytics events using bucketed values such as character count bucket, scenario, and event type. Examples include events like estimate calculated, scenario changed, and text file uploaded.

Prompt Cost Calculator uses hosting and analytics-related services such as Vercel and Supabase. While the application itself is built to avoid intentionally storing prompt text in its analytics table, users should understand that browser-based tools and hosting platforms can still involve normal infrastructure logging or request handling outside the prompt-estimation table itself.

User discretion

Users should not paste sensitive, confidential, or regulated information into the tool if they are uncomfortable using a browser-based estimator. Even when a tool is designed to minimize storage, the safest default is to avoid sharing material that should remain strictly private.

If your workflow requires stronger confidentiality guarantees, internal review, or formal data-handling commitments, treat this MVP as an informational estimator rather than a secure processing environment.

Informational use only

Prompt Cost Calculator is for informational use only and does not provide legal, financial, tax, security, or other professional advice.

If you need legally binding privacy terms, regulated data guidance, or production-grade governance decisions, consult qualified professionals and the official documentation from the relevant providers.
