Droplet
Privacy Policy
Effective 7 July 2026
The short version: Droplet does everything on your own device.
It has no account, no servers, no analytics and no ads, and it sends none of your
browsing anywhere. The text of your web pages and AI prompts is never read, stored
or transmitted.
What Droplet stores
All of the following is kept locally in your browser's extension storage and never leaves your device:
- Your running water totals and the counts behind them (pages loaded, prompts sent), for today and all-time.
- Your settings, such as the chosen estimate basis.
- A short, capped detection log used for troubleshooting, which may include the request URLs of AI services you used and the estimated length of a prompt. You can clear this at any time, and discovery logging is off by default.
What Droplet does not do
- It does not collect, transmit or sell any data.
- It does not use analytics, tracking, advertising or third-party services.
- It does not require an account or any sign-in.
- It does not read the content of the web pages you visit.
- It does not read, store or transmit the text of your AI prompts or the replies you receive.
Permissions, and why they're used
- Storage — to save your totals and settings locally.
- Web request access — to notice that a prompt was submitted by observing that a request went to an AI service. This is observation only: Droplet never blocks, redirects or alters any request, and does not read request or response contents.
- Access to AI sites (ChatGPT, Claude, Gemini, Perplexity) — required only to count prompts on those services.
- Access to all sites — used solely to read the browser's own timing data for how many bytes a page transferred, which is the basis for the page estimate. No page content is read.
How AI prompts are handled
To position a prompt within its estimate range, Droplet reads the length of what you typed in the composer and converts it to an approximate token count on your device. Only that number is used; the prompt text itself never leaves the page and is not stored.
Your control over your data
You can reset all totals and clear the detection log from Droplet's methodology page at any time. Removing the extension deletes all of its locally stored data from your browser.
