A short list, on purpose.
Last updated 7 October 2026
This covers chupke.app in your browser. The Chupke app doesn’t use cookies; what it keeps on your phone is described in our Privacy Policy.
Needed to work
These keep Chupke working and safe, so they can’t be switched off. Most are kept in your browser’s storage rather than as cookies.
| What | Why | How long |
|---|---|---|
| Sign-in (Firebase) | Keeps you signed in on pages that need it, like deleting your account | Until you sign out |
| Sender key | A random key that lets a recipient’s block follow a sender, and keeps limits fair. Only its fingerprint reaches us | Until you clear your browser |
| Your notes and rounds | Remembers the notes you sent and the games you joined on this browser, so you can come back to them | Until you clear your browser |
| Email for sign-in | Remembers the email you asked a sign-in link for, so the link can finish signing you in | Until the link is used |
| Small reminders | Remembers things like a tip you closed, so it doesn’t show again | Until you clear your browser |
| Razorpay or Stripe | When you pay for a Golden Note or Gift Plus, you pay on Razorpay’s page (or Stripe’s, our backup). That page sets its own cookies to process the payment and prevent fraud. They aren’t set on chupke.app | Set by Razorpay or Stripe |
Counting visits
We count website visits with Cloudflare Web Analytics, which sets no cookies and builds no profile of you: we only see totals like which pages were visited, where visitors came from, and their country and device type.
We don’t use analytics cookies. Some game and note pages send our own server a short count, like “a guest joined a game” or “a share card was saved”. It has no cookie, no install key, no account and nothing anyone wrote. It never goes to Google or any other company.
Your control
Every browser lets you see and delete cookies and site storage. Clearing them signs you out and forgets the notes and rounds this browser remembered. Questions: support@chupke.app. More in our Privacy Policy.
