What Poko does
Poko counts the prompts that you submit on AI websites that you explicitly choose to enable (ChatGPT, Claude, Gemini and Perplexity). It displays activity charts, prompt counts, locally calculated prompt-structure heuristics, estimated input token counts, streaks and illustrative input-token API-equivalent costs.
What information is processed
On an enabled AI site, the extension temporarily reads the text within the prompt input when a send-like action is detected, only to calculate: an approximate token count, a numerical prompt-structure score, and a transient in-page duplicate-detection fingerprint. The submitted prompt text is never stored in extension storage, transmitted to the background service worker, uploaded, logged, or included in exports.
Saved local activity records contain: time of submission, the platform name, estimated input token count, numerical prompt-structure score, and (where reliably identified) a model label. The extension also stores user-set permissions, tracking preferences and illustrative price rates. Poko does not access or store complete chat conversations, AI responses, payment details, browser history, passwords, or authentication credentials.
Where data is stored
All activity and settings stay in Chrome's local extension storage on the user's device. Poko has no servers, user accounts, cloud synchronization, remote tracking, advertising SDK, analytics service or outside data-sharing. The extension does not make network requests. Data may be exported by user action to local JSON or CSV files.
Access and consent
Before recording any prompt, Poko asks for affirmative consent. Each supported site is disabled by default; enabling it triggers a site-specific Chrome permission request. Access can be paused or removed in Poko or from Chrome's Extensions settings. No <all_urls> access is requested.
User controls and retention
The user can pause tracking, disable individual sites, adjust historical retention (30/90/180/365 days), export activity or permanently clear activity. Activity is retained locally for the chosen duration, subject to an upper cap of 20,000 records; the default retention is 180 days.
Measurement limitations
Poko estimates input tokens based on prompt text length and calculates an illustrative price by multiplying these estimates by user-adjustable per-platform example rates. It does not measure provider-reported tokens, output tokens, actual API bills, monthly subscription charges or financial savings. Changes to supported websites can affect tracking accuracy and send-action detection.
Children and contact
Poko is a general productivity tracker, not directed toward children. Questions about this policy or the extension: eurolitre@gmail.com.
