Privacy Policy
Last updated: 2026-09-08.
This is the short version, because the long version is also short: AI Token Calculator runs entirely in your browser. There is no server-side processing of any text you paste, no account creation, no API key collection, and no IP address logging on our side. The details below explain what that means in practice.
1. What data the tool collects
None. The page is a static site. When you paste text into the calculator, the token count and the cost estimate happen inside your browser tab using locally-loaded JavaScript and tokenizer files. The text is not transmitted anywhere. Refresh the page and the text is gone.
2. What data third-party services collect
The site loads two third-party JavaScript libraries from the jsDelivr CDN:
- gpt-tokenizer (OpenAI's tiktoken, WASM-compiled) — used for exact token counts on OpenAI models.
- @huggingface/transformers — used for approximate token counts on open-weight models (Llama, Mistral, DeepSeek, Qwen, etc.).
Loading those files means your browser makes a request to jsDelivr's CDN. jsDelivr may log the request (URL, IP, user-agent) per its own privacy policy. We have no control over that and no visibility into it from our side. If you do not want jsDelivr to see your IP, you can block the CDN at the network level or use a browser extension that filters third-party requests — the tool will then fail to load.
3. Cookies and local storage
The site uses your browser's localStorage and IndexedDB only for tokenizer caching — so the HF tokenizer file does not have to re-download on every visit. No cookies are set. No tracking pixels. No fingerprinting.
4. Analytics
The site may load Google Analytics (GA4) on each page view. GA4 records page-view events (URL, referrer, browser type, country) but does not see the text you paste. If you want to opt out, install the Google Analytics Opt-out Browser Add-on, or block googletagmanager.com at the network level.
5. What we do not do
- We do not store the text you paste.
- We do not require you to log in.
- We do not ask for your API key.
- We do not sell data to anyone.
- We do not run ads.
- We do not embed social-media tracking pixels.
6. Children's privacy
The site is not directed at children under 13. We do not knowingly collect data from children.
7. Changes to this policy
If we change this policy in a material way, we will update the date at the top and add a short note in the blog. Material changes are limited to: adding a third-party service, adding analytics, or changing what is stored locally.
