Restrictions on original DouTok AI code do not change third-party library or public-model licenses, or valid earlier grants. Those exceptions take precedence for the material they cover.

Optional website speed measurement

Help us measure this website’s loading speed and response time (LCP, INP, CLS). With your permission, Vercel Speed Insights and our server receive timing values, a general device category and the app section. Chat text and account identifiers are excluded. URL parameters, fragments and document IDs are removed. You can turn this off anytime. Servers receive your IP address during transmission. Our own metrics do not store IP addresses. Our local summaries expire after 15 minutes; exported metrics use the retention settings of the operator and Vercel.

I agree to measuring website speed

1. What is stored

A sign-in cookie, which keeps you signed in and is removed when you sign out. Your language, colour scheme and workspace wallpaper, stored in the browser rather than sent anywhere. Nothing else is written without your agreement.

2. Why it is stored

The sign-in cookie is what tells the server the request is yours; without it the protected part of the service cannot work at all. The preferences exist so the app opens the way you left it.

3. Third parties

Signing in goes through Supabase and paying goes through Stripe, and each sets its own cookie on its own page while you are there. Neither is used to follow you around the web, and DouTok AI embeds no advertising scripts. Optional first-party performance measurement is off until separately enabled in the controls on this page.

4. Your choice

You are asked once, on your first visit, and your answer is remembered. Declining leaves the public pages fully usable; the sign-in cookie is still required to sign in, because there is no way to be signed in without it. Your browser can clear all of it at any time.
